The BT Wholesale checker provides details of the services apparently available for your line from BT Wholesale via various service providers, including services expected soon. The FTTC section should give a speed estimate for most Ewhurst and Cranleigh telephone lines, possibly with an estimated RFS (Ready For Service) date (but this date is only updated quarterly, and connection speeds are subject to actual line quality). If your telephone number is not recognised, then use the address checker. The two links below appear to be alternative interfaces to the same tests; if one fails please try the other.
Many ISP web sites include their own availability checkers, although in most cases these will be less informative than the BT Wholesale check. Once FTTC services are available, the ISP checkers may be helpful, by showing which of their products is suitable for your line speed, e.g. the BT Retail checker.
