MPs’ business costs

David Mundell

IPSA paid £3,428,223 against 4,070 published rows for David Mundell between 2010-11 and 2025-26 as the member for Dumfriesshire, Clydesdale and Tweeddale CC. 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, 2025-26

141 claims, £28,924 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	£491	1.7%
Office costs	Renting and running a constituency office: rent, utilities, equipment, stationery and postage.	128	£25,068	86.7%
Accommodation	The cost of somewhere to stay for an MP whose constituency is far enough from Westminster that IPSA's rules allow it. An MP representing a London seat is not eligible on the same terms.	12	£3,365	11.6%

Every year in the register

David Mundell’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.

A year in which David Mundell joined or left the House part-way through is a part year, and is not comparable with a full one.

Largest claims, 2025-26

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 David Mundell 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.
