4 FAQs about Heat networks

What is a heat network?

A heat network is a shared system for providing multiple properties with hot water and/or space heating (and sometimes, but much more rarely, cooling). It uses a heat source, or sources, to power an energy centre. That energy centre then transfers heat to connected properties in the form of hot water, through a network of insulated pipes.

How many heat networks are there in the UK?

At least half a million households are connected to one of 14,000 heat networks across the UK. From April 2025, all heat network consumers will have access to an official complaints and advice service, and from 2026, new regulations will be in place to better protect those connected to a heat network.

How does a heat network work?

Another set of pipes returns cooler water from the properties to the energy centre. Sometimes a heat network just provides hot water for space heating (e.g. by heating radiators), with the hot water from taps provided separately by an in-property electric immersion heater and water tank.

Why do we need a heat network?

Heat networks are vital to making net zero a reality in the UK. In high density urban areas, they are often the lowest cost, low carbon heating option. This is because they offer a communal solution that can provide heat to a range of homes and businesses by capturing or generating heat locally.
