There is only one way to find out and that is to visit the town and do a lot of internet searching on were surgeries, dentists, shops, services are. Ais there a station where do the trains go, whatabout buses. Thenw what interests do you have are they catered for.
We moved 70 miles last year to a town we were not familiar with, but was nearer our children. We made three or four visits to the area, located services, walked round the town centre. We are in our early 80s.
We surveyed about half a dozen towns in the area we wanted to move to. Towns got rejected for all kinds of reasons, from a lack of town centre parking, poor train service, didn't cater for our interests or limited food shops.
We have been in our new house for nearly six months and are really happy with our decision. there are several doctor surgeries, dental surgeries, opticians and podiatrists within 300 yards of our home. Also 4 supermarkets that cover the market from Waitrose and M&S at one end to Iceland and Lidl at the other There is a Cine Center, lots of cafes and friendly people everywhere.
