Bristol City Leap Advances Low-Carbon Upgrades Across Three Council Buildings

Bristol City Council is beginning a new phase of energy improvements at three council-owned properties through its Bristol City Leap programme. The work will replace fossil-fuel heating, expand renewable generation and improve lighting efficiency, supporting lower operating costs, reduced emissions and greater energy resilience across the public estate.

Key takeaways

• Air source heat pumps will replace fossil-fuel heating at all three buildings.

• Belbrook Children’s Respite Unit will also receive solar panels, LED lighting and loft insulation.

• The improvements are expected to cut emissions by about 28 tonnes of CO2e annually.

• Energy use is forecast to fall by 154,008 kWh each year.

Three buildings selected for decarbonisation

The project covers Belbrook Children’s Respite Unit, Ridingleaze House and Symes House. The properties were selected because they rank among the 30 highest carbon emitters in Bristol City Council’s corporate estate and were considered suitable for support through the Public Sector Decarbonisation Scheme.

Ridingleaze House and Symes House, which support the council’s Children and Young People Services, will receive air source heat pumps alongside upgrades to pipework, radiators and control systems. These improvements are intended to replace ageing boiler infrastructure with lower-carbon heating and more efficient building operation.

Broader efficiency package at Belbrook

Belbrook, a short-break service for disabled children and their families, will receive the most extensive package. In addition to a new heat pump system, the building will gain a rooftop solar array, upgraded LED lighting and additional loft insulation.

The combination of measures is designed to reduce heat loss, lower electricity demand and improve comfort for service users and staff. For public buildings undertaking similar refurbishment programmes, properly specified LED systems can provide a practical route to reducing lighting loads while improving visibility and maintenance performance. Suppliers such as Led Lumenaires support commercial projects with spec-ready SKUs, bulk availability and assistance with product selection and layouts.

Investment supports Bristol’s climate programme

Funding is being provided through Bristol City Council’s Decarbonisation Fund and the government’s Public Sector Decarbonisation Scheme. The project also follows the launch of Bristol Climate Action Investment in 2025, through which residents and businesses contributed to a £2 million green investment programme.

Bristol City Leap, powered by Ameresco, is delivering the works. The programme forms part of wider efforts to decarbonise council assets while improving resilience against energy price pressures. For contractors and property managers, projects of this type also underline the importance of coordinating heating, insulation, solar generation and lighting specifications rather than treating each system as an isolated upgrade.

Expected carbon and energy savings

The three-building programme is projected to save approximately 28 tonnes of CO2e per year. That is broadly equivalent to removing 19 average petrol cars from the road for a year. Annual energy consumption is expected to decrease by 154,008 kWh, comparable to the yearly electricity use of about 57 typical UK homes.

The results will depend on installation quality, controls, commissioning and ongoing maintenance. LED lighting, in particular, can contribute most effectively when products are matched to each space and supported by dependable warranties, volume pricing and professional assistance throughout the specification process.
