The health system in England is a bit different than in other places. As a UK tax payer you will be able to make use of the NHS (National Health Service). It is a very straightforward registration process, instead of going to the central service, you find the GP (general practitioner) closest to you and register there. You will require proof of address and some form of identification; we would suggest taking your passport and visa.
