We're helping the UK achieve its net zero ambitions by developing large, city-scale low carbon heat networks.

What we do

We design, build and operate low carbon, city-scale heat networks. 

We're proud to partner with like-minded and forward thinking local authorities and developers and support them on their decarbonisation journey.

Our heat networks

The Bristol heat network

We're expanding the heat network to support Bristol City Council's city-scale decarbonisation. The network currently serves almost 6,000 customers.

The MEL heat network

Through our joint venture with Midlothian Council, the MEL heat network will intitially supply 3,000 customers and welcomed its first customers in 2024.

The Brent Cross Town heat network

We're working in partnership with Related Argent and Barnet Council to deliver a heat network for 6,700 new homes and three million square feet of commercial space.

Why heat networks?

Listen to our team to learn how heat networks are a core part of the Vattenfall vision and mission, and how they are supporting the UK to meet its climate targets.

Our vision

For more than 100 years we have electrified industries, supplied energy to people's homes and modernised our way of living through innovation and cooperation. 

Our purpose is to enable the fossil freedom that drives society forward. We believe that fossil freedom is the only way society can progress. It's what we're working towards: a future where everyone can choose fossil free ways to move, make and live.

To succeed we must become fossil free ourselves. Vattenfall is aiming for net zero by 2040 across its own operations, suppliers and customers.

Vattenfall has been in the UK for more than 15 years, supporting this vision and making a key contribution towards enabling the UK to reach net zero. We have around 500 employees working for fossil freedom in the UK through our four businesses: onshore wind, offshore wind, electricity networks and heat networks.
