To ask the Secretary of State for Energy Security and Net Zero, what recent assessment his Department has made of the performance and reliability of heat networks operating in residential developments in England; and what steps he is taking to ensure consistent service standards for consumers.

We are aware that some existing heat networks are not delivering to the standard they should be. We have and will continue to take steps to protect consumers: We have already taken action by introducing Ofgem as the market regulator who have the powers to tackle poor service standards. In the first year of regulation, they will be collecting performance data and consulting on Guaranteed Standards of Performance.

Heat network consumers who suffer a service outage can also seek redress through the Energy Ombudsman.

DESNZ is also consulting on mandatory technical standards for heat networks, that include proposals to ensure new and existing heat networks are designed, built, and operated to a standard, that will deliver good outcomes for consumers.
