Interim project manager salary · contract day rates, 2026
What an interim project manager earns, by the day and by the contract
An interim project manager is paid a day rate, not a salary.
IT Jobs Watch’s median contract day rate for a project manager is £538, from 1,242 rates advertised in the six months to 5 October 2026, with London at £575.
Robert Walters puts London project managers in commerce and industry at £650–£1,000 a day on a PAYE contract.
An interim project manager salary is really the day rate times the days sold.
The rate covers full-time work for the life of a project, with no salary, pension or paid holiday behind it.
When you hire an interim project manager through us, we send a shortlist of 3–5, each with day rate, availability and IR35 position set out.

Interim project manager jobs on the board
Interim delivery and operations roles on the board
How fractional recruitment agencies compare is set out in one place, including how we work: a Interim Project Manager brief and a shortlist of three to five.
01/ the role
How an interim project manager is paid, and why the unit is the day
An interim project manager runs one project full-time, from a fixed start to a fixed end: a systems rollout, a migration, a regulatory change, an office move.
They are paid for the days worked, either invoiced through their own company or through a payroll on a PAYE contract.
The APM defines project management by its final deliverables, constrained to a finite timescale and budget.
Project work is the biggest single part of the interim market.
The Institute of Interim Management’s 2026 survey puts project and programme roles at the top of its role types, with about a quarter of all roles.
Across all functions, the IIM puts the average assignment at 10.0 months, the average gap between assignments at 3.2 months and the average days billed in a year at 148.
That makes the day rate the real unit of pay.
There is no salary, no employer pension and no paid holiday, and the interim carries the gaps between contracts.
An interim who works through their own company pays themselves through salary and dividends from what the company earns, after its costs and Corporation Tax.
02/ scope
How to hire an interim project manager
1. Define the project and its end
Say what the project must deliver, by when and within what budget.
A defined deliverable with an end date is what lets you hire by the day.
In central government, the Project Delivery Functional Standard sets the expectations for how projects and programmes are directed and managed.
2. Decide IR35 status at the start
If your business is medium or large, you make the status determination for the engagement and give the contractor your reasons.
Settle it before you go to market, because it changes the rate candidates quote.
3. Check whether it is a project or a programme
Several linked projects that only pay off together need a programme manager.
The APM describes programme management as the coordinated management of projects and business-as-usual work to achieve beneficial change.
Robert Walters puts a London programme manager in commerce and industry at £800–£1,200 a day on a PAYE contract, against £650–£1,000 for a project manager.
What we do on an interim brief
We recruit interim, fractional, part-time, temporary and permanent delivery leaders, and non-executive directors.
We send a shortlist of 3–5, each with day rate, availability and IR35 position set out, and every candidate goes through our five-stage vetting first.
If the project only needs part of a week, hire a fractional project manager instead.

Four taps. The answer names the route for the seat and the page that covers it.

05/ rates by stage
Interim project manager salary day rates by region and sector
Day rates as each publisher states them, all 2026. IT Jobs Watch reports contract day rates advertised in IT job vacancies over the six months to 5 October 2026. Robert Walters publishes PAYE contract day rates with its own averages. Both are contract rates, not rates labelled interim. The IIM figures cover interim managers in every function, not project managers alone. Robert Walters is a recruiter.
06/ economics
Interim pay and IR35: who decides, and what it changes
Tax status turns on how the engagement runs, not on the title or the contract alone.
Under the off-payroll working rules (IR35), a medium or large client makes the status determination; for a small client outside the public sector, the contractor’s own company decides.
The rules apply contract by contract, so one project manager can have engagements on both sides.
It shows in the rates.
The IIM’s 2026 survey puts the average interim day rate at £949 outside IR35 and £830 inside, across all functions.
Robert Walters labels its contract rates PAYE: paid through a payroll with tax deducted, not invoiced by the contractor’s own company.
HMRC’s CEST tool gives its view on a specific engagement, and our IR35 guide sets out the tests.

08/ interim project manager day rate
Interim project manager day rate by region
The interim project manager day rate depends most on where the project is.
IT Jobs Watch’s London median is £575, against £513 for the rest of the UK.
Its regional medians run from £464 in Scotland to £550 in the Midlands.
Robert Walters’ PAYE bands show the same pattern.
London project managers in commerce and industry earn £650–£1,000 a day.
In the regions the bands are £400–£750 in the Midlands, £350–£700 in the North and £400–£650 in the South, with Robert Walters averages of £505, £525 and £560.
Sector adds to the rate.
Robert Walters puts London project managers in financial services at £700–£1,000 a day, and £800–£1,000 in financial services technology.
09/ project manager day rate
Contract project manager day rate, and what it comes to in a year
The contract project manager day rate on IT Jobs Watch has a median of £538, from 1,242 rates advertised in the six months to 5 October 2026.
The range runs from £400 to £700, with the middle half between £456 and £625.
A year earlier the median was £525.
No contractor is paid a salary, but the day rate can be compared with one.
At £538, 220 days would bill £118,360, and the IIM’s all-function average of 148 days billed would bill £79,624.
In London, at £575, the same days bill £126,500 and £85,100.
All four are our arithmetic, a comparison and not a salary.
For scale, Robert Half’s 2026 median for a permanent project manager is £57,000 in base salary, before pension and employer’s National Insurance.

10/ the other routes
Interim, permanent or fractional: which pay basis fits
Interim cover buys a full-time project manager for the life of one project.
A permanent hire is paid a salary for every project that follows; see project manager salary.
If the project needs steady control rather than daily coordination, a fractional project manager on part of the week may cost less over the same months; see fractional project manager jobs.
For the permanent salary spread across part-week days (our arithmetic, not a market rate), see fractional project manager salary.
