Permanent, Interim or Fractional: Which Compliance Hire Does Your Firm Actually Need?

One of the most consequential decisions in a compliance search happens before the search itself starts: deciding whether the firm needs a permanent compliance hire, an interim appointment, or a fractional engagement. Most firms make this decision quickly, often by default, and then find six months later that they chose the wrong engagement type for the actual problem they were trying to solve.

The cost of getting this wrong is real. A permanent hire into a role that did not need long-term ownership is an expensive correction. An interim appointment when the firm needed durable capability creates the same gap a year later. A fractional engagement that the firm scales beyond what the model was designed to handle ends in friction on both sides.

This article works through the decision properly: when permanent is the right answer, when interim makes sense, when fractional fits, how the 2026 changes to the Senior Managers and Certification Regime (SM&CR) affect the choice, and the practical questions that should drive it. It is written for boards, CEOs and hiring leaders at FCA-regulated firms who are about to brief a compliance and risk recruitment search and want to get the engagement model right first.

When permanent is the right answer

Permanent appointment is the default position for most compliance roles at most firms, and for good reason. The compliance function depends on long-term relationships across the business, accumulated knowledge of the firm’s regulatory history, and stable accountability through the conduct rules regime. A senior compliance professional who has been in the role for three years carries institutional context that no incoming interim can match.

The case for permanent is strongest in the following situations.

The role requires a senior manager function that the firm intends to keep stable for the foreseeable future. SMF16 (Compliance Oversight) and SMF17 (Money Laundering Reporting Officer) are both approved functions under the Senior Managers and Certification Regime, which means the FCA must approve the individual as fit and proper before they take up the role on a permanent basis. The regulator can see who holds these functions at each firm, and frequent turnover tends to prompt supervisory questions. A permanent appointment gives the firm a stable answer to the question of who is accountable for compliance oversight.

The compliance function is being built from scratch or scaled up. Firms preparing for FCA authorisation, moving from Limited Scope to Core SM&CR, or growing the compliance team from one person to four, need a permanent leader who will own the design of the function over years rather than months. Interim appointments can fill execution gaps inside this build, but the architect should usually be permanent. For firms at that stage, our Head of Compliance (SMF16) recruitment work starts with the shape of the function before the profile of the person.

The firm is large enough and the role senior enough that the candidate pool genuinely wants a permanent commitment. A Chief Compliance Officer at a large asset manager, or a Head of Compliance at an established bank or insurer, is rarely interested in interim or fractional structures. These candidates expect permanent appointments with full board exposure and a clear career path inside the firm, and a brief that offers anything less will narrow the field.

The role carries personal regulatory accountability that the firm wants concentrated in one individual over time. Where the compliance leader will engage regularly with the regulator, sign off regulatory returns, and be accountable under the conduct rules for a defined scope, permanent appointment gives both the firm and the regulator a stable counterparty.

The cost question: a permanent appointment carries salary, bonus, employer pension, National Insurance and benefits, plus the time and effort of a full search and the regulatory approval process. That is the right cost when the firm needs durable capability, and the wrong cost when the firm needs short-term coverage. Pay for senior compliance roles varies widely by firm size, sector and whether the role carries an SMF, so benchmark against current market data rather than a rule of thumb; our SMF salary guide is a starting point.

When interim makes sense

An interim compliance appointment is the right answer in a defined set of situations that share a common feature: the firm has a real and urgent need for senior compliance capability, but that need is bounded by time, scope or visibility.

The most common interim trigger is a gap in cover. The permanent Head of Compliance has resigned or been promoted out of the function, and the search and FCA approval timeline for the replacement will leave a gap of several months. The firm cannot afford to be without senior compliance leadership during that window. An interim with the right SMF history fills the gap while the permanent search runs in parallel, and the 12-week rule (covered below) gives the firm a defined route to put that person in place quickly.

The second pattern is a regulatory project. The firm is responding to a skilled person review under section 166, building remediation capability after an enforcement action, or implementing a major regulatory change such as the Consumer Duty. These engagements have a definable scope and end-point, and require senior compliance experience that the permanent team does not have. An interim with a specific track record on similar projects is the right answer, and that person often works alongside the permanent Head of Compliance rather than replacing them.

The third pattern is FCA-driven urgency. The regulator has flagged compliance function capability as a supervisory concern, a voluntary requirement is in place, or the firm is preparing for an imminent regulatory visit, and it needs senior compliance experience inside the firm faster than a permanent search can deliver. Experienced interims are usually available on far shorter notice than permanent candidates, who typically have notice periods to serve before an approval application can even be finalised. Our guide to interim SMF16 and SMF17 cover during FCA supervision covers that scenario in more detail.

The fourth pattern is post-acquisition or change of control. The firm has just been acquired by a regulated parent, or sold to a private equity sponsor with different compliance expectations, and needs interim compliance leadership while the new ownership decides what the long-term function should look like. Permanent appointment ahead of that strategic decision is premature; interim cover is the right bridge.

The cost question: interims are paid a day rate with no employer pension, no bonus scheme and no long-term commitment, and the engagement ends when the work does. Day rates are higher than the equivalent daily cost of a permanent employee, so the model is cost-competitive when the engagement is properly scoped and time-limited, and poor value when it drifts on for years because nobody has started the permanent search.

When fractional fits

Fractional compliance is the engagement type firms most often misunderstand. It is not interim by another name. It is not a discount permanent hire. It is a deliberately different model: a senior compliance professional engaged for a defined fraction of their time on an ongoing basis, often one to three days a week, who usually holds similar roles at other firms at the same time.

The case for fractional is strongest in three situations.

Smaller authorised firms where the compliance workload genuinely does not need a full-time senior. A small AIFM, a payment institution with a focused activity, or a Limited Scope firm with a stable book of business may all have meaningful but bounded compliance needs. A full-time Head of Compliance would be over-engineered. A fractional compliance officer two days a week gives the firm proper senior compliance leadership at proportionate cost.

Growth-stage firms still developing the compliance function. A fintech that has just been authorised but is still pre-revenue, or a new wealth management business that wants senior compliance experience without a senior compliance salary on the cost base, can use a fractional engagement to access experienced leadership during the formative period. The model often transitions to a permanent appointment as the firm scales and the workload becomes full-time.

Firms that benefit from cross-firm experience. Fractional compliance professionals who work across several firms see live supervisory patterns, peer firms’ responses to regulatory developments, and how other firms are handling new obligations. That cross-firm view is valuable in itself, and is one of the reasons established firms sometimes choose fractional even when permanent is affordable.

Fractional does not work for every firm or every role. Where the firm needs full-time presence, where the compliance leader needs to be in the office daily, where the workload is genuinely full-time, or where the FCA is likely to expect a more time-committed SMF16 holder given the firm’s size and risk profile, fractional is the wrong model. A fractional SMF holder still needs FCA approval, still carries personal accountability under the conduct rules, and must be able to show the regulator they have enough time to discharge the role. Honest advisers will say this rather than fit the engagement to whatever model their commercial structure rewards.

The cost question: fractional engagements are usually priced as a monthly retainer or an agreed number of days, so the firm pays for senior judgement in proportion to the time it actually needs. That makes it considerably cheaper than a full-time permanent hire of comparable seniority, but only the right choice when the workload genuinely fits the model.

What the 2026 SM&CR changes mean for the choice

The regulatory timetable around senior manager appointments has shifted this year, and it changes the practical calculation, particularly for interim cover.

The 12-week rule is now a submission deadline. Under FCA Policy Statement PS26/6, which took effect on 24 April 2026, a firm covering a temporary or unforeseen SMF absence has 12 weeks to submit an approval application, rather than 12 weeks to submit and receive approval. The person covering can continue to act in the role until the FCA makes its determination, and the Senior Manager Conduct Rules apply to them while they do. The application can be for a permanent or an interim candidate. In practice this takes much of the pressure out of the gap between a departure and an approved replacement, and makes a well-chosen interim a more straightforward bridge than it was.

Approval is still required, and timing still matters. SMF16 and SMF17 remain approved functions. The FCA’s statutory deadline for deciding a complete application is three months, and it has set itself a target of deciding at least half of senior manager applications in 35 days or fewer, measured from January 2026. That is a target, not a guarantee: an incomplete application, a request for more information or an interview stops the clock. Our guide to how long FCA SMF approval takes sets out a realistic timeline.

Further changes are proposed, not yet in force. On 22 October 2026 the FCA published CP26/37, the second phase of its SM&CR review. Among its proposals are extending the period to submit an application for temporary cover from 12 to 18 weeks, replacing the “reasonably unforeseen” condition with a reasonable-use standard for FCA solo-regulated firms, making some senior manager functions notified rather than approved, and removing the Certification Regime entirely. The paper indicates that compliance oversight and money laundering reporting would remain approved functions. The consultation closes on 22 January 2027 and the FCA expects final rules in the first half of 2027, so firms should plan on today’s rules and treat these as proposals only.

None of this removes the underlying question. A firm still needs to decide whether its compliance leadership should be permanent, interim or fractional. What has changed is that the cost of a short gap is lower than it was, which makes interim-then-permanent a more practical route for firms that need time to get the permanent hire right.

A practical decision framework

The decision between permanent, interim and fractional rarely turns on a single factor. The questions that drive the answer most reliably are these.

What is the long-term workload? If the role would genuinely keep a senior compliance professional busy five days a week for the foreseeable future, permanent or interim are the realistic options; fractional will not fit. If the genuine workload is two to three days a week, fractional becomes the most cost-efficient answer.

Is the need bounded by time or scope? If the engagement has a definable end-point, such as a project, a transition or a gap before the permanent hire arrives, interim is the natural answer. If the need is open-ended, interim is rarely the right structure.

Does the role require SMF designation, and how stable should that designation be? Permanent appointments give the firm a stable SMF holder. Interim appointments can be approved for SMF roles, but the firm should be open with the regulator about the time-bounded nature of the appointment and its plan for a permanent successor. Fractional appointments to SMF roles are possible, but the firm must be ready to show that the individual has the time and authority to do the job properly.

Is the firm at a stage where it would benefit from cross-firm regulatory perspective? Firms going through their first regulatory review, building compliance for the first time, or entering a newly regulated sector often benefit from the multi-firm view that a fractional engagement provides. Firms with established compliance functions usually benefit more from concentrated permanent attention.

What is the cost envelope, and how confident is the firm in the workload assumption? If the workload is uncertain and the budget is tight, fractional or interim are lower-risk options than committing to a permanent appointment that may prove over-engineered for the actual need.

Put simply:

• Permanent when the workload is full-time, the need is open-ended and the firm wants a stable SMF holder for years.
• Interim when the need is urgent and bounded: a gap in cover, a remediation project, a supervisory concern or a change of ownership.
• Fractional when the senior workload is real but part-time, and the firm is small, early-stage or values a cross-firm view.

The hybrid path

The decision is not always either-or. Some of the most effective compliance arrangements combine engagement types. A common pattern is interim cover during the permanent search, with the interim either handing over cleanly on the permanent hire’s start date or, in some cases, becoming the permanent appointment themselves. The PS26/6 change to the 12-week rule makes this pattern easier to run, because the firm no longer needs approval in hand within 12 weeks.

Another is fractional leadership at the senior level combined with a permanent compliance officer or analyst at the execution level. This is particularly common at smaller firms where the senior workload is bounded but the day-to-day monitoring, reporting and advisory work is full-time. A third is a permanent Head of Compliance supported by an interim specialist for a specific project, such as a section 166 remediation, so that business-as-usual compliance does not stall while the project runs.

Smaller firms also need to think about combined roles. Where one person holds both SMF16 and SMF17, the choice of engagement model applies to both functions at once, and the time commitment needs to be assessed accordingly.

The hybrid path requires a recruiter that can advise honestly across all three engagement types rather than just the one its commercial model rewards. That is the test for whether a firm is genuinely a compliance recruitment specialist or simply a generalist with a compliance label.

How Exec Capital approaches the question

Exec Capital recruits senior compliance professionals for FCA-regulated firms across permanent, interim and fractional engagement types, from Head of Compliance and MLRO roles up to Chief Compliance Officer recruitment. Every search is run by our specialist team, with Adrian Lawrence FCA, an ICAEW Fellow, overseeing each mandate.

Our first conversation on a compliance brief is rarely about candidates; it is about engagement type. We walk through the workload assumption, the timeline, the SMF question, the cost envelope and the stage of the firm with the hiring leader before deciding what the search should actually look like. Where the right answer is interim or fractional, we say so. Where the right answer is permanent, we run the permanent search end to end, including preparing the candidate for the FCA approval process.

Frequently asked questions

Can an interim compliance officer hold SMF16?

Yes. An interim can be approved as SMF16 in the same way as a permanent hire. Under the 12-week rule, as amended by PS26/6, a firm covering an absence has 12 weeks to submit the application, and the person can act in the role until the FCA decides.

Can a fractional compliance officer be the firm’s SMF16?

It is possible, particularly at smaller firms, but the firm must show the FCA that the individual has enough time and authority to carry out the function. The more complex the firm, the harder that case is to make.

Has the FCA changed the 12-week rule?

Yes. Since 24 April 2026 the 12 weeks is the deadline to submit an application, not to receive approval. CP26/37 proposes extending it to 18 weeks, but that is a consultation proposal and not yet in force.

Is fractional compliance cheaper than permanent?

For the same seniority, usually yes, because the firm pays only for the time it uses. It is only good value if the workload genuinely is part-time; a fractional engagement stretched to cover full-time work tends to cost more and deliver less.

Should we hire an interim while we search for a permanent Head of Compliance?

Often, yes. Interim cover keeps the function running and the regulator informed while the permanent search and approval run their course, and it stops the firm rushing a permanent appointment to close a gap.
