What changes in January 2027
A new regulator for heat networks
From January 2027, Ofgem becomes the regulator for heat networks across England, Scotland and Wales. This brings rules similar to those for gas and electricity. A communal heat network serves one block of flats. A district heat network serves several buildings. Most London blocks built since 2010 have a heat network, with a Heat Interface Unit in each flat.
What heat suppliers need to demonstrate
Heat suppliers will need records for audits. The supplier is often the freeholder, resident management company or managing agent. The records need to show that:
- HIUs are serviced and maintained on a documented schedule
- Repairs and engineer attendance are recorded with audit-grade detail
- Engineers are trained on the specific HIU brands installed in the network
- Billing is grounded in accurate metering and proper unit performance
- Residents have clear prices and a way to put things right if service falls short
How Heat-Plex supports compliance
We provide planned servicing and the records your heat supplier needs. These include digital service certificates after each visit and records of manufacturer-approved engineer training. You have one contact for the whole contract. If you change contractors, we check your service history for gaps. The freeholder, resident management company or managing agent keeps the heat supplier role.
