District heating in the UK continues to gather momentum as the country looks for practical ways to cut carbon emissions from buildings. With heating still one of the largest contributors to UK emissions, heat networks are increasingly being viewed as a scalable, long-term solution — particularly in dense urban areas and large public estates.

Investment and Project Activity Picking Up Pace

Major utilities are stepping up their commitments. Veolia has confirmed a £1 billion pipeline of UK heat network projects planned through to 2030, with around £210 million already committed for delivery during 2025. These schemes span London, the South West, Yorkshire, and parts of the East of England and are focused on expanding low-carbon district heating using waste heat, energy-from-waste plants, and other sustainable sources.

An example of an expanding heating district would be St Ann's Site in north London, where the regeneration project will supply heat to more than 995 homes. Further phases are expected to follow in the future, eventually connecting several thousand more properties. The project uses a steel pre-insulated pipe system that connects all the housing to one heating network, making the system completely sustainable.

Policy Direction and Public Funding

At a national level, district heating remains firmly embedded in the UK’s clean energy strategy. Government modelling still points to heat networks supplying around 20% of England’s heat demand by 2050, compared with just 2–3% today — highlighting both the opportunity and the scale of infrastructure still required.

The government’s recently announced Local Power Plan is also expected to have an indirect impact on the sector. With £1 billion earmarked for community-led clean energy and storage projects, local authorities and community groups may find new routes to support district-scale heating alongside renewable generation.

Meanwhile, councils are reviewing the future of long-established networks. Westminster City Council’s ongoing review of the Pimlico District Heat Undertaking, one of the UK’s oldest schemes, reflects a wider challenge across the sector: ageing infrastructure needs modernisation if networks are to remain reliable and cost-effective.

Regulation and Consumer Protection

Consumer protection remains a key issue. From January 2026, Ofgem has introduced new rules for heat networks, bringing clearer requirements around billing transparency, price change notices, and limits on back-billing. These changes follow public concern over unexpected price rises and opaque tariffs on some networks.

However, campaigners point out that heat networks are still not subject to a formal price cap, unlike gas and electricity. While regulation is moving in the right direction, pressure is building for stronger safeguards as more households are connected.

Technical Developments and Innovation

On the technical side, the sector is becoming more diverse. New and planned schemes increasingly use waste heat from data centres, industrial processes, and energy-from-waste facilities, improving overall system efficiency and reducing reliance on fossil fuels.

There is also continued innovation in pre-insulated pipe systems, which are critical to minimising heat losses across networks. Manufacturers are focusing on improved insulation performance, faster installation, and longer design life — all aimed at reducing whole-life costs and improving reliability.

The Reality for End Users

Experiences with district heating still vary widely. Well-run schemes can offer residents predictable heating, fewer maintenance responsibilities, and lower emissions. Poorly managed networks, however, can lead to high standing charges, billing disputes, and frustration — reinforcing the importance of good governance and transparent operation.

Industry bodies increasingly stress that how a network is managed is just as important as how it is designed.

What Happens Next

The direction of travel is clear. District heating is moving from niche to mainstream as the UK tackles the challenge of decarbonising heat. Strong investment pipelines, growing policy support, and improving regulation all point to continued expansion.

The next phase will depend on striking the right balance — scaling infrastructure quickly while ensuring networks are affordable, reliable, and fair for the people who rely on them every day.
