Anyhow do you have any links to some isp's in the area?
The UK doesn't really have a concept of local ISPs like the US does. The locality only becomes important when you are talking about DSL or cable modem access.
Are you aiming for dialup or DSL/cable ?
If you want DSL then there are lots of ISP, but in the end the company who actually installs and runs the network is BT (British Telecoms) I wouldn't recommend BT as an ISP through.
You can check whether he is likely to get DSL by going here:
http://www.aaisp.net.uk/
Enter his phone number or postcode to check availability.
If you go for DSL then I would recommend:
- A&A
http://www.aaisp.net.uk/
- Plusnet
http://www.plus.net/
If he is going to be the one phoning the ISP when things go wrong then Plusnet would probably be best. If you are going to be the one contacting them then A&A are good because they are a small ISP who are good at dealing with techies, without resorting to "reinstall your drivers" at every turn. Plusnet are a little cheaper, both will supply a pre configured router.
If you want to go for cable then you need to work out which cable company covers his area

Again you need to enter his postcode to work out whether he is covered.
If you want dialup then there are plenty of ISPs to choose from. There are all sorts of complicated packages that will give him certain amounts of toll free Internet access, but I've been out of touch with dialup for years now so someone else will have to fill in the details on that...
...but taking a quick look, for £14.99 a month he can get unlimited access from Freeserve:

...and Plusnet do something similar:
