Sierra Leone, in the early 2000s British forces went in with the UN, and were wildly popular, Tony Blair is still a hero over there, polling showing 70-80% wouldn't mind restored British rule.
How about Singapore?
Singapore, or it makes a deal with China, maybe not communists, to hang on to Hong Kong?
Singapore and HK are islands. HK includes areas on the mainland but the core city is an island.
Not sure if that really counts or matters, but it was a stipulation of the OP that the colony is not an island.
/nit-picking.
What's the largest thing they could keep? If things really go bad in India, could they keep a part of India but the rest becomes independent as multiple states?
Wow, thats weird

Not really. The place is an utter hell-hole. If you had endured 10 years of brutal civil war, you'd probably want the British back too.
Somewhat understandable when one remembers that the UK rolled into town during a decade long civil war, captured the rebel leader within ten days and were completely done with their operation within a month, then proceeded to stay for a while, keep the peace and ensure the return of freedom, democracy and all that lovely stuff.
Not in the Pacific or Caribbean though.
/nit-picking.
Is there any way Britain can retain one of their non-settler colonies that isn't a small island in the Pacific or Caribbean?
Bonus points if the POD is after WWII.
