Flying back to Blighty is good fun and an interesting challenge but you will probably find it considerably cheaper to fly it to an East coast airfield and put it in a container for shipping.
Don't forget that you will need at least one VHF with 8.33 spacing. That plus any other upgrades (perhaps a repaint?) are much cheaper in the USA, we have to pay import duty plus VAT at 20% on everything here so take advantage of your personal goods and chattels exemption!
Whatever you do don't put the aircraft on the UK register.....it's still a very costly and frustrating paperwork nightmare however EASA would like you to think.
