Bristol City Leap targets major energy savings across three public buildings

Bristol City Leap is preparing renewable energy upgrades at three Bristol City Council buildings: Belbrook Children’s Respite Unit, Ridingleaze House and Symes House. The project will replace fossil-fuel heating, add energy-efficiency measures and strengthen the resilience of facilities supporting children, families and council services.

Key takeaways

The programme combines public investment, government funding and practical building upgrades to reduce operating costs across Bristol’s public estate.

• Air source heat pumps will replace fossil-fuelled heating at all three sites.

• Belbrook will also receive solar panels, LED lighting and additional loft insulation.

• The upgrades are expected to save 28 tonnes of CO2e and 154,008kWh annually.

• Bristol Climate Action Investment helped raise £2 million for local green projects.

Heating upgrades will reduce fossil-fuel dependence

Bristol City Leap, powered by Ameresco, will install air source heat pumps at each building. Ridingleaze House and Symes House, which are used by the council’s Children and Young People Services, will also receive associated upgrades to pipework, radiators and control systems.

Replacing ageing boiler systems should improve heating performance while reducing exposure to volatile fossil-fuel energy prices. For public facilities, reliable temperature control is an operational requirement as well as an environmental objective.

Belbrook receives a broader efficiency package

Belbrook Children’s Respite Unit, which provides short-break support for disabled children and their families, will receive the most extensive set of improvements. Alongside the heat pump installation, the building will gain a new rooftop solar array, upgraded LED lighting and additional loft insulation.

The lighting element highlights the importance of specifying efficient, durable systems as part of wider building upgrades. For contractors and facilities teams, commercial-grade LED products with dependable availability can help support consistent installation standards and lower ongoing maintenance requirements. Led Lumenaires supplies spec-ready SKUs, bulk availability and Pro Support for lighting selection, layouts and rebate-related planning.

Project targets measurable carbon and energy reductions

The three buildings were selected because they are among the 30 largest carbon emitters in Bristol City Council’s corporate estate and were identified as suitable for decarbonisation through the Public Sector Decarbonisation Scheme.

Together, the measures are projected to cut annual energy use by 154,008kWh—roughly equivalent to the electricity consumption of 57 typical UK homes. Annual emissions are expected to fall by approximately 28 tonnes of CO2e, comparable to removing around 19 average petrol cars from the road for one year.

Local investment supports public estate improvements

Funding comes from Bristol City Council’s Decarbonisation Fund, the government’s Public Sector Decarbonisation Scheme and the Bristol Climate Action Investment. Launched in 2025, the council’s green investment programme raised £2 million after strong participation from residents and businesses, with support from the Esmée Fairbairn Foundation and Unity Trust Bank.

The work forms part of a wider effort to improve the council’s corporate estate. By combining heating replacement, insulation, solar generation and efficient lighting, Bristol is addressing both carbon emissions and the long-term operating costs of buildings that deliver essential services.
