Find Your MP

Knowing who your Member of Parliament is the first step in almost every form of civic participation. Your MP is determined by where you live, not where you work or were born, and they have a duty to represent every constituent in their seat — regardless of how, or whether, that person voted. The lookup above resolves your postcode to your constituency and current MP through an independent public service, so the result is always up to date, including after a general election or by-election.

A constituency is the geographic area that elects a single MP to the House of Commons. Boundaries are reviewed periodically to keep the number of voters in each seat roughly equal, and a review can move individual streets — sometimes whole neighbourhoods — from one constituency to another. That is why the seat a postcode falls within is occasionally not the one a long-standing resident expects, and why a lookup tied to the current boundaries is more reliable than memory. There are 650 constituencies in total, each returning one Member at a general election.

What your MP can do for you

An MP's work falls broadly into two kinds. The first is policy: how they speak and vote on national questions, which your correspondence can inform. The second is casework: taking up an individual constituent's problem — housing, immigration, benefits, the health service — directly with the relevant authority. There are limits to this: an MP cannot overturn a court ruling, take up a matter that belongs to another representative, or compel an independent body to change its decision. What they can do is ask questions that have to be answered, escalate a case that has stalled, and press a department on a constituent's behalf in ways an individual rarely can. Both kinds of work begin with knowing who represents you and how to reach them.

Once you have found them

With your MP identified, there are several established ways to be heard, each suited to a different purpose:

• Write to them. A clear, specific letter or email remains one of the highest-legitimacy channels available. Our guide to writing to your MP explains what to include and how the correspondence is handled.
• Meet them in person. MPs hold regular local surgeries, and constituents sometimes coordinate larger visits to Westminster. Our report on mass lobbying explains how in-person lobbying works and why it carries weight.
• Contribute to Parliament directly. Beyond your MP, select committees invite written and oral evidence from the public. See our guide to submitting evidence to a select committee.

Why this lookup is always current

This page does not keep its own copy of who represents each constituency. Instead, it hands your search to an independent service that maintains the data live. That means the result reflects the present membership of the House of Commons — so when seats change hands at an election, the answer changes with them, without anything needing to be updated here.
