What is on this site
One question, "heat network regulation", answered with a checker that works on the page with no account, 3 guides on the questions around it, a data table you can cite (the figures and their method), and the sources every figure rests on.
- Registering a heat network with Ofgem: who, what and by when: Existing heat networks must be registered by 26 January 2027, through Ofgem's Comply service. What Ofgem asks for, and why new networks register before supplying.
- What changed for the 2014 metering and billing regulations: The GB notification duty and the cost-effectiveness tool were revoked on 27 January 2026. Metering obligations narrowed but did not disappear, and NI is unchanged.
- Heat network customer rights under Ofgem regulation: Ofgem regulates heat networks for service, reliability, transparent bills and fair pricing, and every GB network must be in the Energy Ombudsman redress scheme.
