Everyone in England and Wales who is on the electoral register receives a polling card several weeks before any election. You are allocated a local polling station and you can't vote anywhere else. You can vote by post without giving a reason but you must apply several weeks in advance. You can get a proxy to vote for you, again which must be arranged in advance, but there's provision for last-minute hitches such as illness. You don't have to take the polling card with you to vote and you don't need any ID. When you arrive at be polling station, the officer in charge takes your details and ticks you off his list. You're then given a ballot paper which bears a unique number, which cannot be used to identify you but which may be used at the count to ensure that there's no fraudulent voting going on.

Polling stations are open from 7 AM TO 10 PM. If there is a queue close to closing time, you will still be allowed to vote even after 10 PM. Polling stations are abundant and no-one has to travel very far. The officer in charge at the polling station must show the empty ballot box at the start of polling to others present in the polling station. The ballot box must be sealed in front of witnesses immediately the voting has ended.

Accusations of fraud are very infrequent, demonstrated fraud even less so.
