Measures#

Each measure is one kind of value you can request, using its id.

“Adds up” means you can total it over areas or convert it to other areas. See Measures and periods for why some can't be combined.

Areas and years#

Request each of these with its geography and code year as geography and boundaryYear.

Things to know#

• Premises able to receive download speeds of at least 30 Mbit/s.
• Availability, not take-up: a premises counts where the service can be ordered, whether or not anyone there has it.
• This is a share of premises, so it does not add over areas. Combining authorities needs a mean weighted by premises, which the source publishes but this measure does not serve; averaging the percentages flat would weigh a small authority as heavily as a city.
• Ofcom's July 2025 Connected Nations snapshot, on local authority codes shared by every release from May 2023 to December 2024.
• Premises able to receive download speeds of at least 100 Mbit/s.
• Premises where a full fibre connection, fibre all the way to the premises, is available.

Corrections and improvements#

These reviewed changes apply to what the API serves for this data. The publisher's source files are not changed; when a code correction applies, the served record retains the publisher's code as sourceAreaCode.

Downloads#

Download complete publisher-observation files instead of paging through the API. Each file has a stable hash and covers one measure, period set and source geography. Any reviewed served code correction is documented and retains its publisher code on the affected record. The source and licence information above applies to these files too; preserve the attribution and note any cleaning or reformatting when you redistribute one.
