Some researchers at the University of Edinburgh have carried out a detailed investigation by postcode and local authority sector for Scotland - see
The cut-off is 1.2 km from the cabinet for 30 Mbps. In addition, the study allows for exchange-only lines. There are two sources of potential error:
(a) It is not possible to take account of the quality of local (copper) network or of lines that do not follow the most direct route to a cabinet. This means that the "true" proportions of the population not able to get SFBB are higher than the estimates suggest.
(b) Details of VM coverage are confidential, so that there will be some areas that can get SFBB from VM that lie outside the cutoff for FTTC.
It seems likely that the poor state of the copper network outweighs the availability of VM service outside FTTC areas.
The estimated percentages of the population not able to get SFBB vary from a minimum of 14% in East Ayrshire, East Lothian & Fife to 30%+ in 9 local authorities. It would be interesting to learn what similar investigations come up with for other countries/regions of the UK.
There is a serious point here. The estimates suggest that the stated targets for the BDUK Step Change and HIE projects in Scotland for coverage of SFBB (even allowing for an adjustment to the 24 Mbps threshold) cannot be met other by some creative reinterpretation of the statistics. If the pattern in urban and suburban areas of Scotland - e.g. local authorities such as Glasgow City (26%) or West Lothian (21%) - is replicated in the rest of the UK, it is equally impossible to meet the DCMS targets for large parts of England.
