Last time I left the UK from Heathrow, I noticed there was no passport control? On my way back into the UK though, there was? I am very confused. Is it the same with Gatwick as well ? I am a British national so don't need any stamps, but if you are a foreigner who stamps your passport now? How long has it been like this? I have a disability and often have assistance to the gate, so maybe it has been the case for a long time and I never noticed?
