I don't dial up for internet access from the UK but I know of a few
companies offering this facility to private users. The main company
is Demon Internet Services. Here are the details
Demon Internet Service tel: 081-349-0063 (a London number)
Price: stlg12.50 to sign up and a flat rate of stlg10.00 per month
You can also send and receive Internet mail through Compuserv but, by
all accounts, it is quite expensive.
