Its about 1.1 miles to the cab from your postcode, so about 1,770 meters so at that distance FTTC can be slower than asdl as you have found out- if their is alot of cross talk this will reduce speeds as well.
Cab 5 on the Bughfield Common exchange was upgraded commercially so no public funding was spent on it.
Phase 1 of the project has a target of 92.3% superfast coverage by the end of 2015, Phase 2 will extend this to 95% or higher by the end of 2017. West Berks will have only reached 82.9% superfast coverage by the end of 2015, so combined with the 95% target their is 12.1% of coverage to upgrade by 2017.
So its a case of waiting to see if Ufton Nervet will be covered by phase 2 of the project, details should be known by Summer.
