Heat networks in plain terms
Heat networks pipe hot water from a central plant to flats and houses, replacing individual boilers. The £90 million investment aims to cut costs by upgrading old systems and expanding new ones that use waste heat or large heat pumps. We expect many households to see lower unit rates once efficiency improves, though bills still split into a usage charge and a standing charge.
New rules and your rights
Ofgem became the statutory regulator on 27 January 2026, giving heat-network customers the same protections as gas and electricity users. Operators must register by January 2027 or face penalties. The voluntary Heat Trust scheme continues during the handover, offering an independent ombudsman route for complaints. We think this shift should reduce past problems with opaque pricing and poor service.
Who benefits and what to check
The money forms part of the Heat Network Transformation Programme and should help homes move away from volatile gas prices. It suits residents in blocks or estates already connected or due to join soon, but savings depend on network efficiency and your property’s insulation. Before signing for a property on a heat network, ask for recent bills, the heat source and whether the operator is Heat Trust registered.
