Broadband Speed

This data includes the average fixed-line broadband speed by output area, based on 2016-2022 data released by Ofcom. The source data file is linked below.

For 2016-2017, CDRC aggregated the supplied postcode data by OA11. For 2018-2021, Ofcom now itself aggregates by OA11, on its Connected Nations data downloads website. For 2022, some data was aggregated by Ofcom by OA21 and some by OA11. CDRC has allocated the OA21 to OA11 geographies on a best-fit basis to allow for continued comparison.

Data files include measures of data coverage and performance with the following variables:

Combined 2016-2022 file (used for all the CDRC Mapmaker maps):

  • (_uf) Ultrafast (UFBB) availability (300mbs+) by % of premises.
  • (_sfu) Superfast (SFBB) availability (30mbs+) by % of premises. This is not mapped on CDRC Mapmaker.
  • (_dow) Average download speed by Mbit/s

Single Year Files by OA11 (For more recent years, download direct from the Ofcom website):

SFBB availability (% premises), UFBB availability (% premises), [for 2016 only NGA availability (% premises)], % of premises unable to receive 2Mbit/s, % of premises unable to receive 5Mbit/s, % of premises unable to receive 10Mbit/s, % of premises unable to receive 30Mbit/s, Median download speed (Mbit/s), Average download speed (Mbit/s), Minimum download speed (Mbit/s), Maximum download speed (Mbit/s), Average download speed (Mbit/s) for lines < 10Mbit/s, Average download speed (Mbit/s) for Basic BB lines, Average download speed (Mbit/s) for SFBB lines, Average download speed (Mbit/s) for UFBB lines, Median upload speed (Mbit/s), Average upload speed (Mbit/s), Minimum upload speed (Mbit/s), Maximum upload speed (Mbit/s), Average upload speed (Mbit/s) for lines <10Mbit/s, Average upload speed (Mbit/s) for Basic BB lines, Average upload speed (Mbit/s) for SFBB lines, Average upload speed (Mbit/s) for UFBB lines, Number of connections < 2 Mbit/s (number of lines), Number of connections 2<5 Mbit/s (number of lines), Number of connections 5<10 Mbit/s (number of lines), Number of connections 10= 30 Mbit/s (number of lines), Number of connections >= 300 Mbit/s (number of lines), Average data usage (GB), Average data usage (GB) for lines <10Mbit/s, Average data usage (GB) for Basic BB lines, Average data usage (GB) for SFBB lines, Average data usage (GB) for UFBB lines, [for 2017 only - FTTP Availability %] [OA11 code].
