Welcome to the Independent Parliamentary Standards Authority Publication website.

On this site you can search for details of the business costs and expenses claimed for by each MP.

You can use the filters to find exactly what you are interested in such as a breakdown of particular costs or expense types or by individual MPs. You can also search for everything claimed by every MP.

In the interests of transparency, we also publish claims which have not been paid or not paid in full.

We publish new information every two months.

Once a year we also publish a summary of the total costs incurred by each MP during the financial year, including staffing costs and details of any connected parties (such as partners or relatives) they employ.
