MPs’ business costs
Andy Slaughter
IPSA paid £3,009,489 against 1,167 published rows for Andy Slaughter between 2010-11 and 2025-26 as the member for Hammersmith BC, then Hammersmith and Chiswick BC. These are the costs of running an office and employing staff under IPSA’s rules. They are not salary, and the largest part of them is wages IPSA pays to the member’s employees rather than money the member receives.
By category, 2024-25
80 claims, £286,001 paid. The headings are IPSA’s own categories grouped; the categories inside each are named on the register page.
| Category | What it covers | Claims | Paid | Share |
|---|---|---|---|---|
| Staffing | The salaries and employment costs of the people an MP employs to run their office and casework. IPSA pays these directly; they are not money an MP receives. | 1 | £257,728 | 90.1% |
| Office costs | Renting and running a constituency office: rent, utilities, equipment, stationery and postage. | 77 | £28,199 | 9.9% |
| Travel | Journeys between the constituency and Westminster and within the constituency. Until 2018-19 IPSA published one travel category; from 2019-20 it publishes travel by the MP, by staff and by a dependant separately. | 2 | £74 | 0.0% |
Every year in the register
Andy Slaughter’s own years, not the register’s: the first is 2010-11 and the last is 2025-26. Figures are not adjusted for inflation, so a rise between two distant years is partly a rise in prices. Select a year to read it on its own.

Largest claims, 2024-25
The 15 rows IPSA paid most against, with IPSA’s own description of each. Read the description before the amount: IPSA publishes most of a member’s staffing as one row for the whole year — “Total Staffing budget payroll costs for the ⟨year⟩ year” — so the largest row here is usually a year of wages for the member’s employees and not something bought.

What this page does not show
Whether any of it was justified. IPSA accepted these claims under its own rules and the register records what was paid, not whether it should have been. A large total is not a finding about the member.
Nor how Andy Slaughter compares with another member. After staffing the largest headings are accommodation and travel, and both are decided mostly by where a constituency is: a member several hundred miles from Westminster is eligible for costs a member with a London seat is not. Two members’ totals are two sets of rules as much as two sets of choices, and the length of service differs too.
It is also not pay. IPSA sets and publishes MPs’ salaries separately and they are not in this register; the staffing figure here is the salaries of the member’s employees.
