British Email Format

British uses the first.last format, so Jane Smith would be jane.smith@gov.uk.

HMRC is the British tax, payments, and customs authority responsible for collecting the revenue that funds public services. From April 2026, sole traders and landlords earning over 50,000 pounds annually must use Making Tax Digital for Income Tax, replacing the traditional annual self-assessment return with quarterly digital reporting.

GOV.UK One Login is the British government's single sign-in and identity verification system, used by over 13 million people to access more than 120 government services. It is designed to become the only way to sign in to all central government services by 2027.

Yes, Clay can help you enrich a list of British government contacts by looking up verified email addresses using the first.last@gov.uk pattern. This is useful when you need to reach civil servants across specific departments and want to confirm addresses before outreach.

The British government lists over 600 departments, agencies, and public bodies on GOV.UK in 2026, including 24 ministerial departments such as the Cabinet Office, HM Treasury, the Home Office, and the Foreign, Commonwealth and Development Office.
