Your MP is paid to represent you, but that does not mean every letter lands well. The ones that get replies tend to share the same qualities: they are clear, local, specific and easy to answer. A rant may make you feel better; a well-built letter is more likely to make something happen.
Know who you are writing to, and why it matters
MPs represent everyone in their constituency, including people who did not vote for them. That is the first practical point. If you live outside their constituency, you are not their constituent, and they are unlikely to take up your case. Check your postcode on Parliament’s website or the MP’s own site if you are unsure.
If you are writing about someone else, make sure you have their permission to share personal details. For casework, the MP’s office will usually ask for consent before acting.
Policy or casework?
Most letters fall into two types. A policy letter asks your MP to take a position, vote a certain way, raise an issue or write to a minister. A casework letter asks for help with a specific problem: benefits, immigration, housing, NHS waits, tax or a council decision. Be honest about which one you are writing. It changes the tone, the evidence and the ask.
Decide your ask before you write
Before you type a word, finish this sentence: “I want my MP to…” If you cannot complete it, the letter will drift. One issue per letter works best. If you care about three things, write three letters or choose the most urgent. MPs and their staff triage correspondence, and a focused request is easier to act on.
Your ask should be something an MP can actually do. They can raise a debate, write to a minister, sign a motion, attend a meeting, refer you to a service, or explain their position. They cannot overturn a court judgment, approve a visa or fix a hospital appointment by snapping their fingers. Ask for the right thing and you are more likely to get a useful answer.
The shape of a letter that gets read
Short letters are not rude. They are respectful of time. Aim for one side of A4, or roughly 300 to 500 words. Use this structure:
- Subject line. Make it specific: “Constituent request: support for the Renters’ Reform Bill” or “Casework: housing repair delays, reference 12345”. Avoid vague subjects like “Important issue”.
- Your details. Full name, full postal address including postcode, email and phone number. If you are writing on someone else’s behalf, include their details and a line confirming they consent.
- Opening. Say who you are, that you are a constituent, and why you are writing. One or two sentences. “I live in [road or area] and I am writing about…” is enough.
- Context. Give the facts in plain English. If it is personal, explain the impact on you or your family. If it is policy, say why it matters locally. Use dates, reference numbers and a short timeline if relevant.
- The ask. Be direct. “Please write to the minister asking for…” or “Please raise my case with the council and ask them to…” If you want a reply by a certain date, say so and explain why.
- Close. Thank them for their time. If you know their name, end with “Yours sincerely”. If you do not, “Yours faithfully” is the traditional form. Include your contact details again if they are not in the letterhead.
Keep paragraphs short. Use headings or bullet points if they make your case clearer. Do not bury the ask at the bottom of page two.
Tone: polite, personal, persuasive
You can be angry and still be effective. The trick is to aim the anger at the problem, not the person reading it. Insults, sarcasm and party-political lectures give an office a reason to file your letter under “no action”. A calm, firm letter is harder to dismiss.
Write in your own words. Campaign templates have their place, but a copied-and-pasted email is easy to spot and easy to answer with a standard reply. Add one or two sentences about your own experience. That is what makes your letter different from the hundreds of others.
If you have relevant expertise, mention it briefly. If you are a nurse, a landlord, a small business owner or a carer, say so. If you are writing about a local issue, name the street, school, hospital or service. MPs respond to constituents, not abstract causes.
Do not threaten. Do not say you will never vote for them again unless you mean it, and even then it rarely helps. Do not demand a meeting the next day unless it is genuinely urgent. And do not send the same letter every day. Persistence is useful; harassment is not.
Timing and practical details
Email is usually faster. Most MPs have a contact form or a parliamentary email address. If you post a letter, use the correct address: House of Commons, London SW1A 0AA, or their constituency office. Check their website first. Some MPs ask for casework to go to the constituency office and policy letters to Westminster.
Parliament goes into recess at points in the year. MPs still work in their constituencies, but votes and debates pause. If your letter is about a bill, send it before the relevant debate if you can. If it is urgent, say why. Do not mark everything urgent.
Keep a copy. Note the date you sent it and how. If you need a reply before a deadline, give a reasonable date and explain the reason. “I would be grateful for a reply by 14 March, as the committee is meeting on 18 March” is clear. It also gives the office something to work with.
If you do not hear back
MPs receive a lot of correspondence, and offices vary. If you have not heard anything after a few weeks, send a short follow-up. Attach or forward your original letter. Do not rewrite it from scratch. A polite nudge is often enough.
If you still hear nothing, phone the constituency office. Ask for the caseworker or the person who deals with your issue. Keep a note of who you spoke to and when. If your matter is urgent, ask about the MP’s next advice surgery. These are usually advertised on their website or in local newspapers.
If you need specialist advice on benefits, immigration, housing or legal matters, contact a qualified adviser or solicitor as well. An MP can raise a problem and ask questions, but they are not a substitute for professional casework.
A simple template to adapt
Dear [MP’s name],
I am a constituent living at [your full address and postcode]. I am writing about [one issue].
[Two or three sentences of context. Include dates, reference numbers and the impact on you or your community.]
I would like you to [specific action]. Please let me know what you are able to do.
I would be grateful for a reply by [date] because [reason]. Thank you for your time.
Yours sincerely,
[Your name]
[Email and phone number]
A final checklist before you send
- Are you writing to your own MP?
- Have you included your full address and postcode?
- Is there one clear issue and one clear ask?
- Have you kept it short and factual?
- Would you be happy for a member of staff to read it aloud?
- Have you kept a copy and noted the date?
Send it, then be patient. A good letter does not guarantee the answer you want, but it gives you the best chance of a reply that engages with your point. That is what representation is for.
