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.
