What is a Heat Network?

Heat networks are part of the UK’s plan to cut carbon emissions from heating. By connecting buildings into shared systems, we can make better use of local renewable energy, reduce reliance on fossil fuels, and build a more efficient and resilient energy future.

What is Communal Block Heating?

Communal heating, also known as block heating, is where a single central energy system provides heating & hot water to all the homes in one building. Instead of every flat having its own boiler, heat is produced in a central plant room and distributed through insulated pipes to each home. Inside each flat, a Heat Interface Unit (HIU) gives residents control over their own heating and hot water, just like a boiler would, but with fewer parts to maintain.

What is District Heating?

District heating is a type of heat network that connects multiple buildings across a wider area.  Heat is generated in a central location and distributed through insulated pipes. Instead of each building having its own boiler, they are supplied with ready-to-use hot water from a shared system. This makes it much more efficient and cost-effective, especially when the heat comes from sources that would otherwise go to waste.

How Does It Benefit Me?

For residents, communal heating means improved reliability, lower maintenance, and often lower energy bills, especially when paired with smart meters and fair billing.

Over time, it’s also easier to upgrade the central plant to use cleaner, cheaper energy sources, like heat pumps or waste heat from nearby industry, without needing to change anything inside individual homes.
