Mobile coverage datasets
Measures
Each measure is one kind of value you can request, using its id.
| Measure | Unit | Combining areas |
|---|---|---|
4G mobile coveragemobile-4g-coverage | % of premises | Not combined |
5G mobile coveragemobile-5g-coverage | % of premises | Not combined |
“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.
| Areas | Code year | Periods | Covers | Records |

Things to know
- Premises with an indoor 4G signal from all four mobile network operators. Indoor coverage is modelled by the publisher, not measured at each premises.
- This is a share of premises, so it does not add over areas. Combining authorities needs a premises-weighted mean, and the weight is not served here; averaging the percentages flat would weigh the Isles of Scilly as heavily as Birmingham.
- Premises with an outdoor 5G signal from all four mobile network operators, at the publisher's high-confidence threshold. 5G is reported outdoors only.
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.
| Change | What the API serves | Applies when |
|---|---|---|
| Opt-in canonical measure-unit presentation | On the explicit canonical request, each numeric value and any publisher-supplied interval bound is multiplied by the measure's declared scale; the response names the resulting unit and calculation. | GET /v1/data/{measure-id}?units=canonical |

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.
