You can use the valid visa in your expired passport when you're travelling to and from the UK. You'll need to travel with your expired and your new passport.

In 2026, the rules for UK visas have shifted significantly due to the mandatory transition to eVisas. As of February 2026, the UK government no longer issues physical visa stickers (vignettes) or BRP cards. Your "visa" is now a digital record linked to your passport. If your passport expires, your permission to enter the UK remains valid, but you must update your UKVI (UK Visas and Immigration) account to link your new passport to your digital status before you travel. If you still have an old-style physical sticker in an expired passport, you generally must carry both the old and new passports together, but in 2026, transport carriers (airlines) are increasingly required to verify your status digitally. Furthermore, for non-visa nationals, the new Electronic Travel Authorisation (ETA), which became mandatory for all visitors in early 2026, officially expires when your passport does, requiring a new application.
