01/ the role

What interim chief of staff services cover

An interim chief of staff works full-time for a fixed term to cover a gap, lead a change or see a transaction through, then hands over.

Interim executives are hired for immediate impact: they expect to take decisions from the first week.

The service covers the leadership team’s operating rhythm and meetings, tracking company priorities and decisions to completion, special projects the CEO cannot run personally, and board preparation and internal communication and acting as a trusted adviser and sounding board to the CEO.

If you are weighing the options, the same seat is also bought as fractional chief of staff services, part-time chief of staff services, or a permanent hire, set out on the chief of staff services hub.

02/ scope

What is in scope — and what is not

In scope

The leadership team’s operating rhythm and meetings; tracking company priorities and decisions to completion; special projects the CEO cannot run personally; board preparation and internal communication; acting as a trusted adviser and sounding board to the CEO.

Not in scope

The chief of staff does not replace functional leaders; they coordinate and unblock.

Diary and inbox management belong to an executive assistant.

Chief of staff or a neighbouring seat?

A chief of staff manages priorities and projects; an executive assistant manages the CEO’s time; a COO owns operations.

The scoping test: write down the three decisions you need the chief of staff to own in the next ninety days. If you cannot, you are not ready to brief.

07/ how it runs

How an interim chief of staff engagement runs from brief to hand-over

Brief.

You tell us the scope, the start date and the length of the mandate, and what success looks like in the first ninety days.

A clear brief names the decisions the chief of staff will own.

Shortlist.

We come back with 3–5 interim chief of staffs against the brief, each with day rate, availability and IR35 position set out, assessed through our five-stage vetting.

Mandate.

The interim chief of staff starts with a written mandate and a review point.

Interim executives are judged on the outcome of the mandate, and the good ones plan their hand-over from the first week.

Hand-over.

When the mandate ends the interim chief of staff hands over to the permanent appointment, often having helped to choose them.

08/ before you sign

Before you buy interim chief of staff services three checks

Standing.

Check professional standing and references before you sign: directors stay legally responsible whoever they bring in; see GOV.UK guidance on being a company director.

Status.

Agree how the engagement will run in practice, because that decides its IR35 status; HMRC’s guidance for clients sets out who makes the status determination.

Scope.

Write down what is out of scope.

The chief of staff does not replace functional leaders; they coordinate and unblock.

Diary and inbox management belong to an executive assistant.

09/ questions

Interim Chief of Staff services FAQ

The questions people ask before bringing in an interim chief of staff.

The chief of staff seat’s full scope: the leadership team’s operating rhythm and meetings; tracking company priorities and decisions to completion; special projects the CEO cannot run personally; board preparation and internal communication; acting as a trusted adviser and sounding board to the CEO. The chief of staff does not replace functional leaders; they coordinate and unblock. Diary and inbox management belong to an executive assistant.
It depends on scope, sector and days. We do not publish a band for this seat because no source we can verify publishes one; each candidate on our shortlist states their own rate, so you compare like with like.
An interim chief of staff works full-time for a fixed term, usually to cover a gap or lead a change. A fractional chief of staff works a standing number of days each week, often for several clients, for as long as the business needs it.
A CEO who is the bottleneck, decisions that do not get followed through, a leadership team without a rhythm, or a big change programme with no owner. Interim is the right shape when the work is full-time and time-bound.
It depends on how the engagement runs in practice — control, substitution and whether the chief of staff is part and parcel of your organisation. For medium and large private-sector clients, the client makes the status determination. Each candidate on our shortlist states their IR35 position.
You brief us on the scope, the days and the start date. We come back with a shortlist of 3–5 interim chief of staffs, each with day rate or salary, availability and IR35 position set out, assessed through our five-stage vetting.
