For passing through the UK to another country. DATV (no border control) or Visitor in Transit (through border control).
A UK transit visa may be needed if you are changing flights in the UK on your way to another country.
You may not need a transit visa if you already hold certain UK permissions (for example, a valid Standard Visitor visa) — always verify based on your route and documents.
Comparison: Transit rules can be stricter than you expect. If you are also planning transit through Canada or USA, check each country’s transit rules separately — the fact you have a visa for the final destination does not always remove the need for a transit permission.
