Free health check for your communal heat network

Thousands of communal heat and hot water networks in the UK are old or operating inefficiently.
The carbon and cost implications of these inefficiencies can be significant.


To help housing providers assess the efficiency of their heat network(s) Sustain, part of the Anthesis Group, are offering a free heat network health check service. Simply complete Sustain’s online form and one of their engineers will undertake a free of charge review, analyzing your data and calculating your network performance.

Sustain’s free heat network health check report includes:

  • An overview of your network energy usage.
  • Current performance against industry benchmarks.
  • Advice regarding next steps and how to improve network performance.

Please note that Sustain can only review up to three heat networks free of charge and these must be connected with housing. Analysis of more than three networks or subsequent analysis will be chargeable.

Not a housing provider?

If you’re operating a heat network which isn’t connected to housing, please contact Sustain and they’ll be happy to assist.
