The recent House of Commons debate on superfast broadband tabled by the new MP Matt Warman revealed to us that MPs are using data from the summer of 2014 when talking about superfast coverage, which is woefully out of date given the pace of the roll-outs. Our own Broadband Availability Tool lets you search through the 650 UK constituencies but we thought it worthwhile publishing the full list of 650 and updating this periodically.

While many will be familiar with the data and terms involved it would be irresponsible to not include some explanatory notes.

  • The data represents fibre based coverage we were aware of as of 24th June 2015.
  • While the phase 1 target is 90% superfast coverage, this is a NATIONAL target, not a per constituency target, thus those constituencies with more than 90% coverage subsidise those under the target.
  • The overall UK Superfast Coverage is 83.6%, with fibre based coverage at 88.5%.
  • Ranking gives the order from 1 to 650 with respect to superfast coverage.
  • We use a definition of 30 Mbps or faster to define superfast. For those constituencies where the project is working towards a 24 Mbps definition you can usually add an extra 1 to 3% in terms of coverage.
  • The difference between fibre based superfast based is because of the line distance variability of VDSL2. We use a fairly pessimistic prediction that takes into account a lot of cross-talk i.e. speeds likely once take-up is high.
  • We update our availability tool data weekly, sometimes more often.
  • FTTP refers to availablilty of GEA-FTTP from Openreach, i.e. where 40, 80, 200 and 300 Mbps options are available. This is sometimes called native FTTP or native FTTH, this is NOT FTTP on Demand (FoD)
  • The USC, USO and 15 Mbps columns utilise ADSL/ADSL2+ data to predict an overall result.
  • The Universal Service Commitment target is meant to 2 Mbps for all in 2015, and some areas are pretty much there. Note: Figures listed are at 0.1% resolution, so there may still be a few premises missing out.
  • USO – the 5 Mbps figure is only a proposal by the Government at this time, but this gives an idea of the work needed.
  • Under 15 Mbps figure is given since some projects have a coverage at this speed clause, and it also represents the speed at which a household can usually stream multiple HD streams at the same time.
  • Mbps = Mega bits per second

    I hope you’ve drawn the attention of the HoC Library to this data.
