You will need a rear fog light fitted. I guessing the only way to keep the rear end looking nice is to get one of the rare clusters converted to a UK one with the fog light in. Otherwise you will have to stick a third party on somewhere. The good news is you can leave your steering wheel on the wrong side. ;-)

I've bowled at Lakenheath a few years back. Lakenheath is in the county on Suffolk which is where Ipswich is.
