The UK’s space programme was built around hydrogen peroxide. Initially it was used to assist jet aircraft off of the ground by direct decomposition with a silver catalyst to produce high pressure steam and oxygen. When rockets were required, they used kerosene as a fuel. The hydrogen peroxide was decomposed with a catalyst and the exhaust was used to spin the pumps. The hot, oxygen rich exhaust was then combined with kerosene to drive the main engine.
If you look at the British rockets they were TINY and their exhaust is near invisible.
Sadly the programme was cancelled before the first satellite launch. The UK did launch one satellite (Prospero - still up there and still transmitting), but then everything was broken up and the expertise lost.
