Hello and (an early) welcome.
There are three Doctors practices in Downham Market. We use 'The Howdale Surgery' and would recommend them to anyone.
http://howdalesurgery.co.uk/There are two dental practices in Downham Market, you may even be able to register as an NHS patient with one or other if you are really lucky! You need to visit them in person to register if at all possible.
Our pet rabbit was always cared for by 'The Hollies' vet clinic (Downham Market), which is a part of the London Road practice of King's Lynn. I am happy to recommend their service based on my experience.
http://www.lrvc.co.uk/index.htmlThere are two pet shops in Downham (Downham seems to have two of everything!).
'Claws and Paws' is in 'Fairfield Road', next to the railway line on the opposite side from the main station building.
'Animal Magic' is in the High Street, near to the Nationwide Building Society office.
'Bearts' at Stowbridge ( a couple of miles away) do all things horsey (I know nothing about heese).
http://www.bearts.co.uk/If you are new to things like oil fired heating, septic tank emptying and the like, be sure to ask advice of a neighbour or on here before appointing anyone to do or supply anything. It is easy to be ripped off when you first arrive here, by, for instance, being charged £150 to empty the septic tank when you ought to be paying no more than about £60.
This forum is a good place to seek advice, do not be shy about asking.
