If your home is in Ealing
Ealing's residential extensions guidance (SPD 4) uses a general limit of 3m deep and 3m high for single-storey rear extensions, with more possible on detached houses or where neighbours are well separated. The guidance is old, so how much weight it now carries should be checked case by case.
