Press & methodology
The Milton Project is a free, independent database of who funds UK MPs. Journalists, researchers and students are welcome to use the figures, charts and downloads on this site.
Where the data comes from
Every figure on this site is derived from the House of Commons Register of Members’ Financial Interests, published by the UK Parliament and accessed through the official Members API. We do not add, estimate or infer any donation that is not in the register.
The register is checked automatically each day. New entries appear on the latest declarations feed shortly after Parliament publishes them.
How donors are identified
Register entries are free text. We parse the standard fields Parliament uses — “Name of donor”, “Address of donor”, “Value”, “Date received” and, for outside earnings, “Payer” and “Payment”.
Donor names are normalised (titles such as “Rt Hon” and suffixes such as “Ltd” are stripped) so the same donor giving to several MPs is grouped into a single profile. This is how we can show that one donor funds multiple MPs.
Sector labels on donor profiles are assigned by automated classification and reviewed where contested. They are descriptive, not authoritative — always check the underlying register wording, which we reproduce in full on every entry.
Known limitations
Amounts are taken from the register as declared. Where an entry states a value in a non-standard format, no amount is recorded rather than a guessed one — so totals are conservative.
The register covers sitting MPs only. Former members, peers and party-level donations reported to the Electoral Commission are outside its scope and therefore outside ours.

Corrections and contact
If a figure looks wrong, it is almost always because the underlying register entry is ambiguous — tell us and we will look at the parsing. Corrections, data requests and interview enquiries are welcome via the details on the about page.
