Coverage, clearly.
PowerLogs records the power cuts that network operators publish under open licences. What it can show depends on what each operator publishes.

Past power cuts: who publishes them
Every operator records every power cut and reports yearly totals to Ofgem. Whether the details are published, and how easy they are to get, varies widely. Where they are published, they come as technical data files rather than a record you can look up. Checked 1 November 2026.
| Network operator | What is published | How to get it | How PowerLogs uses it |
|---|---|---|---|
| Northern Powergrid | No history published. Its open data portal shows live power cuts only. | Not available | Recorded live by PowerLogs only |
| UK Power Networks | Every unplanned cut from April 2021 to March 2025, with start and end times, homes affected and cause. The location given is the substation that supplies the area, not individual streets. | Free account on its open data portal | Not used yet: nothing after March 2025, and too broad for a postcode record |
| National Grid Electricity Distribution | No history published. Its data portal shows live power cuts only. | Not available | Recorded live by PowerLogs only |
| SP Electricity North West | Every unplanned cut since 1997, with start and end times, homes affected, cause and a location point. Updated monthly. | Free account on its open data portal | Imported from 1 April 2026; shown as possibly affecting the nearest postcode sector |
| SP Energy Networks | Faults since April 2010, with start times, homes affected, cause and substation, but no end times. | Free account on its open data portal | Not used: without end times, a cut’s length is unknown |
| Scottish and Southern Electricity Networks | Faults on its higher-voltage network, updated weekly, with report times, homes affected, cause and average time off supply. Each fault is located by an internal network reference, not a place. | Free account on its data portal | Not used: it can’t be matched to postcodes, and smaller local cuts aren’t included |
| NIE Networks | Not checked yet. | – | Not yet collected |
The limits matter
PowerLogs can only keep cuts it has seen, or that an operator has published, so each operator’s record starts on the date shown above. Periods when an operator’s data could not be read are shown as missing.
Some operators leave out cuts that affect only a few homes. Homes on independent networks, often newer estates, may not appear at all. Network boundaries are approximate; if you are unsure who runs your network, call 105.

Your postcode is enough to start
Full postcodes only appear on the page for that postcode; area pages use districts and sectors. Email alerts store your email address and one postcode, nothing else. A name and address typed into a claim email stay in your browser and are never saved. Privacy notice
