Your exchange is ADSL enabled, and our initial check on your postcode indicates that your line should be able to have an ADSL broadband service that provides a fixed line speed up to 2Mbps.
Our check also indicates that your line currently supports an estimated ADSL Max broadband line speed of 7Mbps; typically the line speed would range between 6Mbps and 8Mbps.
Our check also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 15Mbps; typically the line speed would range between 8.5Mbps and 19Mbps.
The actual stable line speed supportable will be determined during the first 10 days of use. This speed may change over time, to ensure line stability is maintained.
