Briefly, UK agent was ShipMyCar.com and they arranged pretty much everything.
UAE to UK plus all UK paperwork, and tax/MOT/plates/service was about £3300. Only thing you have to do is get the Car export test certificate in the UAE and fill it with all your stuff! (Contents will not be insured however)
They were very polite and did a great job, but the comms eg progress reports were a bit lacking.
Bottom line, well worth it overall and I'm driving my beloved Mustang again over here.
