Two addresses? Make your vote count where it matters

If you are registered to vote at two addresses — a second home, or home and university — you choose where to cast your general election vote. Enter both postcodes and we will show you where a tactical right-of-centre vote makes the bigger difference.

The rules

General elections: one vote only. You may be registered at two addresses, but you can vote in only one constituency. Voting twice at a general election is a criminal offence.
Local elections are different. If your two addresses are in different council areas, you can vote in both councils’ elections.
Students can be registered at both their home and term-time addresses — the same one-vote rule applies at a general election.
Not registered at your second address? You can register on GOV.UK in about five minutes.

“Impact” measures how close the projected race is between the strongest right-of-centre party and the strongest party that is not. The closer the race, the more likely a single vote is to decide it. Where the right is projected to lose only because its vote is split, the seat is scored on the result a united right would get. Postcodes are looked up to find the constituency and are not stored.
