How Much Does an Interim Headteacher Cost?

A practical guide to interim headteacher costs for proprietors, boards and school business leaders

This is usually the second question a board asks, and it’s an entirely reasonable one. Budgets in independent special schools and alternative provision are tight, often tied directly to pupil numbers, and nobody should feel awkward about wanting a straight answer on cost.

The difficulty is that a single figure, given without context, tends to mislead. Interim leadership is priced differently from a permanent appointment, and comparing the two side by side will almost always make the interim look expensive when it may not be at all.

What we can do is explain how the cost is built, what pushes it up and down, and how to work out what you’re actually committing to before you pick up the phone.

How much does an interim headteacher cost?

Interim school leadership is charged as a day rate, and that rate varies considerably depending on the role and the setting.

Deputy headteacher, assistant headteacher, SENCo, designated safeguarding lead and compliance leadership placements sit at the lower end of whatever range you’re quoted. Headship, executive headship and placements into complex, residential or regulated settings sit meaningfully higher, because the interim is carrying significant risk and accountability from the first morning.

If a quote comes in well below the market, it’s worth asking what’s included. In our experience something is usually being left out, and most often it’s the vetting or the support around the placement once it starts.

How is interim leadership priced?

Interim leaders are almost always engaged on a day rate rather than a salary. You pay for the days worked, and the engagement ends when the brief is complete.

That structure has consequences worth understanding. There’s no pension liability, no notice period beyond what you agree, no redundancy exposure, no recruitment advertising cost, and no cost of a failed permanent appointment. There’s also no cost during school holidays unless you specifically ask for them.

Set against that, the daily figure is higher than a permanent head’s salary divided by working days. It carries the interim’s own costs, the absence of employment security, and the provider’s cost of finding, vetting and supporting them properly.

What drives the day rate?

Seniority. A headteacher or principal costs more than a deputy or a compliance lead.

Complexity of the setting. A residential independent special school under regulatory action needs a different calibre of leader from a settled forty pupil AP, and the market prices that difference.

Length of engagement. Longer, more certain engagements usually attract a better rate than open ended or short notice cover.

Urgency. Emergency cover starting next week costs more than an appointment planned for September.

Days per week. Rates aren’t always linear. A leader giving you five days will often price differently per day from one giving you two.

Location and travel. Where a setting is remote or requires accommodation, that will show up somewhere in the figure.

What are the contracting options?

Through a provider. The provider engages the interim and invoices you. This is simplest for the school, and the provider carries the vetting, the contracting and usually the cover if the placement doesn’t work out.

Direct engagement. You contract with the interim or their limited company yourself, sometimes after an introduction fee. Cheaper on paper, but you carry the safer recruitment responsibility, the IR35 assessment and the risk.

Umbrella arrangements. Common where the interim isn’t operating through their own company.

Whichever route you take, be clear about IR35 status from the outset. For genuine interim headship arrangements the assessment needs to be made carefully, and getting it wrong is an avoidable problem that lands months later.

What does interim deputy and specialist cover cost?

Boards often assume interim cover is only worth commissioning at headship level. On cost grounds the opposite is frequently true.

An interim deputy at the lower end of the range, two days a week for a term, is a modest commitment against what it protects. A headteacher covering their own deputy’s role for two terms is doing two jobs badly, and the cost of that shows up later as staff turnover, a slipped improvement plan, or an inspection outcome nobody wanted.

The same applies to specialist appointments. An interim SENCo or designated safeguarding lead for a term costs considerably less than headship cover and often addresses the actual problem more directly.

A worked example

A forty pupil independent special school loses its deputy head, who held behaviour and safeguarding.

Option one. The head absorbs it. The cost on paper is nothing. The cost in practice is a head working sixty hour weeks, a safeguarding function held by someone with no time to hold it properly, and a permanent recruitment run by an exhausted leader.

Option two. An interim deputy, three days a week for one term. There’s a real invoice attached to that. The head keeps their own job, safeguarding stays properly held, and the permanent recruitment is run well rather than under pressure.

Neither option is automatically right, and for some settings the first genuinely is the better call. But boards that only ever compare the second figure against zero aren’t comparing the real alternatives. The first option has a cost too. It just arrives later, and it lands somewhere other than the budget line, usually on staff and on children.

How do you compare fairly against a permanent salary?

If you want a genuine comparison, build both sides properly.

On the permanent side, include salary, on costs, pension, recruitment advertising, the cost of the search process, and the realistic risk that the first appointment doesn’t work out. On the interim side, include the day rate multiplied by the days you actually need, and nothing else.

Boards that do this exercise honestly are often surprised. For a two term engagement covering a genuine gap, the difference is smaller than the headline rate suggests. For a three year appointment it isn’t, which is exactly why interim leadership is a bridge rather than a destination.

From our experience

The most expensive decision we see is under commissioning. A board worried about cost appoints two days a week when the setting needs five. Six weeks later nothing has moved, because there was never enough leadership time to move it. The engagement then extends by a term to catch up, and the cheaper option has quietly become the more expensive one.

Many leaders tell us afterwards that they knew at the time it wasn’t enough. The board wanted a number it could defend, and two days felt defensible in a way that five didn’t.

The second pattern is conversion fees discovered late. A board is impressed by an interim, decides to appoint them permanently, and finds a substantial fee they hadn’t budgeted for. It’s easily avoided by asking at the start.

A common misconception

“Interim leadership is a premium product for schools with money.”

It’s understandable that boards see it this way, because the day rate is visible in a way that most other costs aren’t. But interim leadership is one of the few things a setting commissions where the cost of getting it wrong is measured in terms rather than pounds.

An underpowered placement in a specialist school can cost you staff, pupils, commissioner confidence and a regulatory outcome. More importantly, it costs children a period of stable education they don’t get back. Those are the expensive numbers, and they rarely appear on an invoice.

Questions for boards and proprietors

• Have we worked out how many days the role genuinely needs, rather than how many we’d like to pay for?
• Do we have the rate, notice, conversion and failure terms in writing?
• Have we made the IR35 assessment, and can we evidence it?
• Are we comparing like with like against a permanent appointment?
• What would it cost us, in money and in time, if this placement doesn’t work?

Our perspective

Cost matters, and asking about it early is a sign of a board doing its job properly.

The point is to ask it alongside the other question. Not just what does this cost, but what does this need to achieve for it to have been worth it. Settings that hold both questions together tend to commission well, and they tend to end the interim period stronger than they started it, with the children in the school having noticed very little disruption at all.
