Written question asked by Rachel Blake (Labour) on Tuesday, 24 March 2026, in the House of Commons. It was due for an answer on Thursday, 26 March 2026. It was answered by Martin McCluskey (Labour) on Wednesday, 1 April 2026 on behalf of the Department for Energy Security and Net Zero.


Heat Networks: Outages

Question

To ask the Secretary of State for Energy Security and Net Zero, whether his Department holds data on the frequency and duration of outages affecting heat network customers.

Answer

Historically, heat network performance, including outage duration and frequency has been unregulated in Great Britain, and as such the Department does not hold this data.

As the newly appointed market regulator for heat networks, Ofgem now have powers to collect performance data, and they will be consulting on introducing Guaranteed Standards of Performance.

The Heat Trust operate a voluntary scheme for heat networks, and participating heat networks are required to submit data to demonstrate their compliance with the scheme’s service standards.

The most recent report is available on their website.
