Expenses

MPs claim back money for running an office and working in two places. An independent body, IPSA, publishes every claim. This is what was paid in 2025-26.

PAID IN 2025-26
£10,711
Office costs · claims for running an office£9,485
Accommodation · claims for somewhere to stay£1,226

52 claims. For comparison, across the 657 MPs in IPSA’s file the middle MP was paid £18,469 and the average was £19,699.

Costs depend on many things, such as where an MP’s area is, what premises and staff they need, and whether they joined or left part-way through the year. This page does not say whether any amount is right or wrong. It covers the claims in IPSA’s individual business costs file, so it is not the full cost of an MP’s office.

Siân Berry voted the same way as their party in 204 of the 205 votes where parties gave instructions (100%), and went the other way in 1.

What does this mean?

Parties tell their MPs how to vote. Most MPs usually follow that. A high or low count says nothing on its own about whether an MP is good or bad, and we do not rank MPs by it. We only count votes where parties gave instructions, not free votes. How we count it
