Hi
You'll get many responses saying where they live and why they love it as examples !
Take a look at your current and expected lifestyle and choices you have or might perhaps be wanting to make and then begin to shortlist potential suitable villages, towns and cities you think may suit. Research those some more and narrow the ones which are best until you have perhaps 3/4 places?
The 'larger' airport helps narrow it down already though - Heathrow (Gatwick, Luton & City for the London area), Birmingham, Manchester, Glasgow perhaps being the best choices for flights that regularly serve the US which also give you the best choices and availability.
Very recently, I've been very pleasantly surprised at the area called Finchhampstead which is near/around the Reading, Camberly and Bracknell areas - wouldn't mind living around there!
