Next year I'm going to the UK. Shortly after that my passport expires. Is this a problem? I know that for some countries, the passport has to be valid for at least 1 year more. How is it in the UK?

Your passport must be valid for at least 6 months beyond the date of return from your trip. It cannot be damaged and any alterations/extensions must be endorsed by the Home Office or relevant Embassy.
