Who Sends Letters from the House of Commons
MPs are given House of Commons stationery and postage-paid envelopes for their parliamentary work. That includes representing individual constituents and taking up their problems. So a letter in a House of Commons envelope almost always comes from an MP or their office, usually your own.
The Most Common Reasons
- A reply to you. You, or someone in your household, wrote, emailed or filled in a contact form, and this is the answer.
- A casework update. Your MP took up your issue with a council, government department or agency, and is passing on their reply.
- A reply to a campaign email or petition. If you signed one through a campaign group, it may have gone to your MP, and some MPs reply by post.
- A letter about a local issue. MPs sometimes write to people in their area about something local, or to ask their views.
What It Is Not
A letter from the House of Commons is not a court summons, a fine or a tax demand. Jury summonses come from the Jury Central Summoning Bureau in Bradford, not from Parliament. House of Commons stationery cannot be used for party political campaigning, so it should not be an election leaflet either.
Not Sure Why You Got It?
Check the letterhead for your MP's name and any reference number, and ask anyone you live with whether they contacted your MP. Still unsure? Call the House of Commons on 020 7219 3000 and ask for your MP's office. Be wary of any letter that asks for payment or bank details, and check it through that number before doing anything.
How to Reply to Your MP
Quote any reference number from their letter and include your full address, so they know you live in their constituency. A posted reply is a proper, dated record. With PostRight you type your reply online, and we print it and post it to House of Commons, London SW1A 0AA, from £2.79.
