Retained vs Contingent Executive Search — When Each Fits

Retained executive search is an exclusive engagement in which the search firm is paid in stages as the work progresses and, in return, researches the whole market and approaches people who are not looking for a new role. Contingent search is paid only if the firm’s candidate is hired, is usually non-exclusive, and works mainly from candidates who are already active or already known to the recruiter. The short answer to “which should we use?” is this: use retained search when the best candidates are employed and not looking, when the appointment is confidential, or when a failed hire would be expensive — which covers most C-suite, board and senior director roles. Use contingent search when the candidate pool is large and active, and when speed and cost matter more than reaching the whole market. For employers hiring in the capital, see our London executive recruitment service.

Those two models are different services, not two prices for the same service. Retained search buys a managed, research-based process with one accountable firm. Contingent search buys access to a recruiter’s existing network with no upfront cost and no commitment. Both work well in the right situation, and both produce consistently poor results when used in the wrong one.

This guide sets out the structural differences between retained and contingent search, the middle-ground options (engaged and container search), the situations in which each approach fits, how exclusivity, fees and guarantees usually work, how interim and fractional searches are priced, and the mistakes organisations most often make when choosing a model. It is written from the perspective of a firm that runs retained executive search for senior executive and board appointments, and that also places interim and fractional executives.

The choice is not simply a cost question, though the fee structures differ. It is a question about what the appointment requires, which candidate pool needs to be reached, and what level of partnership between client and search firm is appropriate. Getting the choice wrong tends to produce one of two outcomes: paying contingent fees for a process that never reaches the candidates the role needs, or paying retained fees for a transactional role that could have been filled through contingent recruitment or a direct advertisement.

Retained vs Contingent Search at a Glance

The table below compares the three main commercial models side by side. The terms vary from firm to firm, so treat it as a description of common practice rather than a fixed rule — the engagement letter is what governs any individual search.

How Retained Search Works

Retained executive search is a professional services engagement, normally paid in three stages: an instalment at engagement, a second on delivery of the shortlist and a final instalment on appointment. The fee is usually calculated as a percentage of the successful candidate’s first-year remuneration, though some firms charge a fixed fee agreed at the outset. Fixed fees are more common among advisory boutiques; percentage fees remain the norm for traditional headhunting firms. VAT is charged on top in the usual way.

The retained engagement gives the search firm the economic stability to invest in the assignment — to build a thorough market map, to identify the best-qualified candidates regardless of whether they are actively looking, to approach those candidates directly, and to manage the slow and careful process of engaging someone who was not thinking about moving. The fee structure ties the firm’s incentive to quality (finding the best candidate, not the fastest one) rather than speed alone.

Exclusivity — one firm on the assignment — allows the opportunity to be represented consistently and credibly. Candidates take a retained approach more seriously than a multi-firm contingent approach, because an exclusive engagement signals that the opportunity is genuine and that the firm truly represents the client. When several firms approach the same candidate about the same role at the same time, it signals either that the role is hard to fill or that the client lacks a coherent search strategy — neither of which helps.

The retained process typically follows a defined structure: a brief development session with the key stakeholders to understand the role’s requirements, culture and candidate profile; a market mapping phase that identifies the universe of qualified candidates; a direct outreach phase in which the search team approaches candidates individually; a longlist presentation with brief profiles; structured assessment of the longlisted candidates; a shortlist presentation; final-stage interviews managed by the client; reference checking; and offer support. Our executive reference checking guide covers the referencing stage in detail. This end-to-end managed process is qualitatively different from receiving a batch of CVs.

How Contingent Search Works

Contingent search operates on a success-fee-only basis — the firm is paid only on placement. The fee is normally a percentage of first-year base salary and is generally lower than a retained fee, reflecting the different service model and the fact that the recruiter carries all of the risk of not being paid. The client may work with several contingent firms at once, and often advertises the role directly at the same time.

The contingent model’s economics create a specific incentive: the firm needs to limit the time spent on any one assignment, because it may earn nothing for it. Contingent firms therefore work predominantly from their existing candidate database, supplemented by job boards, LinkedIn and network sourcing. The research investment needed to identify the best passive candidates — people who are employed, not looking, and who need a careful approach from a credible source — rarely makes economic sense in the contingent model.

This is not a criticism of contingent recruitment as such; it is a description of how rational firms behave within a particular commercial model. The best contingent recruiters are excellent within it: fast access to an established candidate pool, efficient processing of active candidates, and competitive pricing for transactional appointments. The model’s limits are structural, not failures of execution — and for many roles below director level they do not matter at all.

Engaged and Container Search: The Middle Ground

Between fully retained and purely contingent search sits a group of hybrid models, usually called engaged search, container search or exclusive contingent search. The labels are used loosely and the terms differ between firms, but the common features are an upfront commitment fee (smaller than a first retained instalment), exclusivity for a defined period, and the balance of the fee payable on appointment. In many arrangements the upfront element is credited against the final fee, so the client pays no more in total than under a contingent agreement if the search succeeds.

The commitment fee changes behaviour on both sides. The search firm can justify proper research rather than a database trawl, and the client has a reason to give the brief real attention instead of treating the search as one of several speculative options. Exclusivity means candidates hear about the role from one source, so the opportunity is presented consistently.

Engaged search suits roles where the candidate pool is partly active and partly passive — senior finance, operations or commercial roles below the C-suite, or a first senior hire in a growing business where the budget is limited. It is less suited to board appointments, CEO successions and highly confidential searches, where the full retained process and its staged accountability are worth the cost. If you are offered an engaged arrangement, check three points in the terms: how long the exclusivity lasts, whether the commitment fee is refundable or credited, and exactly what research the firm commits to doing in return.

The Core Difference: Passive vs Active Candidates

The question that decides whether retained or contingent search is appropriate is simple: where does the best candidate for this role sit today? If the best candidate is actively searching — they have registered with recruiters, they respond to calls and they can interview promptly — contingent search can find them efficiently. If the best candidate is employed, performing well and not looking, which is the usual situation for senior executive roles, only a research-and-outreach method will find and engage them reliably.

Executives who are performing well in their current roles are often the strongest candidates for a new opportunity, and they are the least likely to be applying for jobs or responding to generic recruiter messages. The retained firm’s advantage is the ability to identify these people through systematic market mapping and to approach them with a well-briefed, specific conversation about an opportunity that is compelling enough to make them listen.

The implication for seniority is clear: the more senior and specialised the role, the more likely the best candidates are passive, and the more the retained method matters. At C-suite and director level in organisations of any real size, retained search is the norm. Lower down, the deciding factor is less the salary than the shape of the candidate pool — a specialist role with a small, employed talent pool can justify retained search well below board level.

When to Use Retained Search

Retained search is the appropriate model when any of the following conditions apply. First, when the best candidates are predominantly employed and not actively looking, which is true for almost all senior executive and board appointments. Second, when the role is specialised enough that the candidate pool is small and needs careful research to map — a CFO with regulated financial services experience, a Chief Medical Officer for a pharmaceutical business, a COO with a renewable energy background. Third, when confidentiality requires that the search is managed through a single trusted intermediary rather than disclosed to several competing firms; our confidential executive search guide explains how that is run in practice. Fourth, when the appointment is consequential enough that the organisation wants a managed partnership rather than a database-driven response.

The cost comparison should be made on a total-cost-of-appointment basis, not on the fee alone. A contingent hire that is cheaper at the outset but leaves or underperforms within eighteen months costs the original fee, plus the disruption of a failed appointment, plus a second search. The retained model’s better outcomes at senior level are where its value lies, even at a higher headline fee. That does not mean the retained fee is always justified; it means the comparison has to include the cost of getting the hire wrong.

When to Use Contingent Search

Contingent search works well for roles where the candidate pool is well defined, large and contains active job-seekers; for roles below director level where a retained fee is out of proportion to the commercial significance of the appointment; for volume hiring where speed and database access are the main requirements; and for organisations with strong employer brands, where inbound candidate flow makes a passive-candidate campaign unnecessary.

Mid-level commercial, technical and operational roles at well-known employers — where the employer’s reputation generates strong interest and the hiring volume justifies a fast, efficient process — are the strongest use case. Roles where a retained fee would add disproportionate cost relative to the hire are also natural contingent territory, and many businesses run their general executive recruitment below board level on a contingent or advertised basis while reserving retained search for the top team.

The key diagnostic question is: “If I advertised this role on LinkedIn and the main job boards today, would the people who apply include the best available candidates?” If yes, contingent recruitment or a direct hire may be enough. If no — because the best candidates are employed, their track record is not publicly visible, or they would never respond to an advertisement — retained search is needed to reach them.

The Multi-Firm Contingent Failure Mode

One of the most common senior hiring failures happens when an organisation briefs three or four firms at once on a contingent basis for a senior appointment. The client, wanting maximum coverage, assumes the competition will produce better results. In practice the outcome is usually worse than a single retained search.

Each firm invests little in the assignment, because its expected return is a fraction of a fee if it gets lucky. Candidates receive several approaches about the same role from different firms — a red flag that suggests either that others have turned the role down or that the client is disorganised. Each firm picks from its existing database rather than doing the research the assignment needs. The candidate who hears about the same opportunity from three different firms in a week is not receiving a professional, compelling representation of the client; they are receiving noise. There is also a practical problem: when two firms submit the same candidate, the question of who “owns” the introduction can turn into a fee dispute.

The firms that succeed in this environment are those with the most actively searching candidates on their books — which is precisely not the population that produces the best senior appointments. Organisations that have had a disappointing retained search sometimes switch to multi-firm contingent recruitment for senior roles. This is usually a mistake: the right response to a poor retained search is to choose a better retained firm and a better brief, not to adopt a model that is structurally unsuited to senior hiring.

Exclusivity: What It Means and When to Grant It

Exclusivity means the client agrees that one firm will handle the search for an agreed period and will not brief other agencies on the same role. It is standard in retained and engaged search, and it is the main thing a client gives up in return for the firm’s commitment. It is worth understanding what exclusivity does and does not cover before signing.

Exclusivity normally covers other search firms and recruitment agencies. It does not usually stop the client considering internal candidates, but the engagement letter should say whether a fee is payable if an internal candidate or someone the client already knew is appointed. Many retained firms charge the full fee whoever is appointed, on the basis that they have run the market test that makes the internal appointment credible; others exclude named internal candidates. Neither approach is wrong, but it needs to be agreed at the start, not argued about at the end.

Grant exclusivity when the role needs a consistent message to the market, when confidentiality matters, or when you want the firm to invest in research. Keep the period realistic — long enough for a proper search, with a review point if progress stalls. And pair exclusivity with clear service commitments in return: a named consultant, a defined process, agreed reporting and an honest update if the market is telling the firm something the brief does not want to hear.

Evaluating and Selecting Retained Search Firms

The criteria for evaluating a retained search firm for a senior appointment should cover: sector and function expertise — does the firm know the talent market for this role? Research method — how does it identify passive candidates who are not already in its network? Off-limits policy — which companies can it not approach because of existing client relationships, and does that meaningfully constrain the candidate pool? Diversity approach — does it routinely produce diverse longlists, or does diversity appear as an afterthought? And the team — who will actually run the assignment day to day, not just who pitches for the business?

Reference conversations with clients who have used the firm for comparable appointments are the most valuable input. Ask specifically: did the firm produce candidates who were not in its network at the start? Did the shortlist meet diversity expectations? Did the search run to the agreed timetable? Was the consultant accessible? What happened when the preferred candidate declined — did the firm solve the problem or simply report it? These questions reveal actual performance rather than the pitch.

Off-limits policies deserve particular attention. A search firm with many existing client relationships in a sector may be unable to approach a large share of the best candidates, because those candidates work for clients it has agreed not to recruit from. A firm with deep sector expertise but a long off-limits list may, paradoxically, be less effective than a firm with slightly less sector depth but fewer restrictions on the candidate pool.

Fee Structures, Payment Terms, and Guarantees

Retained fees are most commonly expressed as a percentage of the appointee’s first-year remuneration. Firms define remuneration differently — some use base salary only, others include guaranteed bonus or other fixed elements — so check the definition rather than comparing headline percentages. Some firms charge a fixed fee agreed at engagement that does not vary with the final package. Fixed fees work well when the salary range is known precisely; percentage fees are more common where there is real flexibility in the package. Expenses such as advertising, travel or psychometric assessment may be charged separately, and the engagement letter should say so.

The payment schedule is commonly split into thirds against engagement, shortlist and appointment, though some firms use two stages for shorter searches. The engagement instalment is normally non-refundable if the client cancels — it pays for research already done — but reputable firms will usually discuss a fair arrangement if the role is cancelled for genuine business reasons rather than because the client wants to change firms mid-search. Contingent fees, by contrast, become payable on the candidate’s acceptance or start date, as the terms specify.

The replacement guarantee — what happens if the appointee leaves within an agreed period — varies by firm. In retained search the usual remedy is a free replacement search if the appointee leaves within the first few months; some firms offer longer protection for very senior roles. Contingent terms more often provide a sliding-scale refund. Either way, the guarantee should be written into the terms along with its exclusions — it typically does not apply if the appointee is made redundant, if the role changes materially after appointment, or if invoices have not been paid on time.

In the UK, recruitment firms that introduce candidates to clients are subject to the Conduct of Employment Agencies and Employment Businesses Regulations 2003, which set requirements on matters such as agreeing terms with clients before services are provided. The government’s overview of the Conduct Regulations is a useful plain-English summary. Whatever model you choose, make sure the fee basis, payment triggers, exclusivity terms and guarantee are all agreed in writing before the search begins.

How Fractional and Interim Searches Are Priced

Interim and fractional appointments are priced differently from permanent search. Instead of a placement fee based on salary, the client usually pays a day rate for as long as the executive works. The day rate covers the executive’s own fee and the firm’s margin; in most arrangements the firm invoices the client, pays the executive (often through the executive’s own limited company or an umbrella company) and keeps the difference. Some firms quote the client an all-inclusive day rate; others show the executive’s rate and the firm’s margin separately. Ask which basis is being used, so that you are comparing like with like between providers.

An interim executive typically works full time for a defined period — covering a vacancy, running a turnaround or delivering a project — and is billed for the days worked. A fractional executive works a set number of days a week or month on a longer-term basis, and the same day-rate principle applies to a smaller number of days. Because the firm is paid as the executive works, there is usually no upfront retainer for interim and fractional searches, and speed matters: these searches depend on an existing network of available executives rather than a long research campaign. For a fuller comparison of the three engagement types, see our guide to fractional, interim and permanent hiring.

Three points in interim terms deserve attention. First, the notice period on both sides, which is often short. Second, the conversion fee if you decide to take the interim on permanently: where the executive is supplied through an employment business, the Conduct Regulations restrict when such a transfer fee can be charged, although limited-company contractors can in some circumstances opt out of the Regulations, so read the clause carefully. Third, employment status: if the executive works through their own company and your organisation is medium or large, you are responsible for deciding whether the off-payroll working rules apply. HMRC’s guidance on understanding off-payroll working (IR35) explains who makes the determination.

Retained Search for Specific Appointment Categories

Board and NED appointments are almost always run on a retained basis, for three reasons. First, the candidate pool — serving non-executives and executives with board experience — is small and has to be researched. Second, board appointments, particularly successions involving sitting directors, need the confidentiality of single-firm management. Third, listed companies are expected to run a formal, rigorous and transparent appointment process: the UK Corporate Governance Code expects open advertising and/or an external search consultancy to be used generally for chair and non-executive appointments, and any consultancy used to be identified in the annual report. Our board construction guide for listed companies covers the governance requirements in more detail.

CEO and CFO appointments are almost always retained, reflecting both the seniority of the roles and the confidentiality most of these searches involve. A CEO search in particular is often run while the incumbent is still in post, which demands the controlled process that retained search provides. Our guide to hiring a CEO sets out the full appointment framework.

Scale-up and venture-backed businesses making their first professional C-suite hires — a first professional CFO, a first VP Sales or a first Chief Product Officer — benefit particularly from retained search, because the brief for these roles is often underdeveloped (the founder may not have hired at this level before) and the candidate profile is nuanced (the executive needs to complement the founder, not replicate them). A search firm that invests in brief development, helping the founder set out what the business actually needs from the appointment, adds disproportionate value here.

Appointments at FCA-regulated firms add a further layer. Where the role is a senior management function, the firm must be satisfied that the candidate is fit and proper and, for most such roles, obtain regulatory approval before the person takes up the function. That makes the depth of the search and the quality of referencing more important, and it lengthens the overall timetable — another reason regulated firms tend to use retained search for senior roles.

How Exec Capital Approaches Retained Search

Exec Capital runs retained executive search for CEO, CFO, COO and senior director appointments, and for board roles, across financial services, technology, professional services, industrial and consumer sectors. We work with large corporates and growing businesses, and with boards and investors as well as executive teams. Our retained process covers brief development, market mapping, direct candidate outreach, structured assessment, diverse longlist construction and referencing before offer. Interim and fractional appointments are handled on a day-rate basis rather than a retainer. Our sister firm FD Capital specialises in CFO, FD and finance leadership appointments, and NED Capital handles non-executive director and chair search. If a role would be better served by a contingent arrangement or a direct advertisement, we will say so.

Internal Sourcing and Direct Hire as Alternatives

Beyond retained and contingent search, organisations have two further options: internal sourcing (using the HR or talent acquisition team to run the search directly) and direct hire through advertising (posting on LinkedIn, job boards and specialist sector sites without a search firm). Both are viable for some roles and should be considered honestly before commissioning a search.

Internal sourcing works best where the talent acquisition team has deep relationships in the specific talent market, the employer brand is strong enough to attract strong applicants, and the HR function has the capacity to give a senior search the time it needs. Large organisations with dedicated executive talent teams can run credible internal searches for senior functional roles. At smaller organisations without that infrastructure, the team typically lacks the specialist market knowledge and the senior credibility with passive candidates that the most senior appointments require.

Advertised direct hire — posting the role and screening applicants — works for roles where the candidate pool is large and actively searching. An advertised senior role can attract a large volume of applications, which creates a screening burden that needs either real HR capacity or a disciplined screening method. The quality of the applicant pool is usually lower than a retained search would produce, because the best employed candidates rarely apply to job postings; but where a strong pool of active candidates exists at the required level, an advertised process can produce excellent results at low cost.

Hybrid Models: Advertised Process within Retained Search

Many rigorous retained searches include an advertised element alongside research and direct approach. Advertising the role — even when the expectation is that the best candidates will come from research — serves two purposes. It gives access to active candidates who may be excellent despite being on the market. And it supports governance expectations at public bodies, regulated firms and listed companies, where the appointment process has to show that it was open and competitive.

For public sector appointments, open competition is often a formal requirement rather than good practice: Civil Service appointments, for example, must be made on merit on the basis of fair and open competition. At regulated firms the emphasis is different — the firm has to be able to show that it assessed the candidate’s fitness and propriety properly — but a well-documented, competitive process helps with that too. Retained firms working with these organisations build the advertising and open-access requirements into the retained method rather than treating them as alternatives to it.

Getting the Most from Your Retained Search Partnership

The quality of a retained search is decided by the client as much as by the search firm. Organisations that invest in the partnership — thorough briefing, responsive engagement throughout and clear decisions at each stage — consistently achieve better outcomes than those that commission the search and then become passive recipients of candidate presentations.

The brief development stage is the most important investment the client can make. A brief grounded in a genuine understanding of what the organisation needs — what the role requires, what the culture demands, what success looks like, and what is essential versus desirable — gives the search team a candidate profile it can work from consistently. A brief that is vague, internally inconsistent, or that changes materially after research has begun wastes the early work and extends the timetable.

Feedback on longlisted candidates should be prompt and specific. The search team uses it to refine its understanding of the client’s preferences and to redirect the research if the first market map has not produced candidates who fully meet the requirement. Feedback that is delayed by two or three weeks, or that is generic rather than specific about what the presented candidates lack, prevents that iteration and produces a shortlist that is less well targeted than it should be.

Interview scheduling should be managed to avoid calendar drift. Senior candidates balance a search process against demanding day jobs. Long gaps between stages consistently cause candidates to lose interest, accept other opportunities that have moved faster, or conclude that the client’s indecision signals deeper problems. Moving promptly through the stages — while taking the time needed for good decisions — is the most important timing discipline a client can impose on itself. Finally, plan the offer before you reach it, so that the package for the preferred candidate is agreed internally before the final interview.

Frequently asked questions

What is the main difference between retained and contingent search?

Retained search is exclusive and paid in stages as the work progresses, so the firm can research the whole market and approach people who are not looking. Contingent search is paid only on placement, is usually non-exclusive, and relies mainly on active candidates and the recruiter’s existing network.

Is retained search more expensive than contingent?

The headline fee is usually higher and part of it is payable whether or not an appointment is made. Contingent fees are generally lower and only payable on success. The fairer comparison is total cost of appointment, including the cost of a failed hire or a second search.

What is container or engaged search?

A hybrid model with a smaller upfront commitment fee, a period of exclusivity and the balance of the fee on appointment. The upfront element is often credited against the final fee. It suits senior roles below the C-suite where some research is needed but a full retained process is not.

Do I pay a retained fee if the role is cancelled?

Instalments already invoiced are normally non-refundable, because they pay for work already done. Later instalments are not usually payable if the search stops. Check the cancellation clause before you sign.

How are interim and fractional executives charged?

Usually on a day rate for the days worked, which covers the executive’s fee and the firm’s margin, rather than a placement fee based on salary. Ask whether the rate quoted is all-inclusive and what applies if you later take the executive on permanently.

Should I use more than one search firm for a senior role?

For senior appointments, rarely. Several firms approaching the same candidates dilutes the message, compromises confidentiality and reduces each firm’s investment. One well-chosen retained firm with a clear brief usually produces a better shortlist.
