School project
The Diocese of Guildford has taken a significant first step towards decarbonising its entire school estate, by installing low carbon heating systems at 11 schools across Surrey.
The move is part of a long-term sustainability programme supported by funding from the government’s Public Sector Decarbonisation Scheme (PSDS), which is administered by Salix Finance.
The project – from heat loss calculations and energy efficiency audits to grant applications and management of the installations – was overseen by ReEnergise. Following a competitive tender process, Viessmann Climate Solutions was selected as the heat pump technology supplier, providing air source heat pump systems tailored to each school’s requirements.
The units ranged from the compact 10kW Viessmann Vitocal 150A heat pump at Newdigate Pre-School to a 384kW system using three Vitocal 200A Pro units at The Priory School in Dorking. In total, 15 individual systems were installed across 11 schools, with the works carried out by Aston Cord Energy Services between July 2024 and March 2025.
Now fully commissioned and operational, the new systems are expected to save over 466 tonnes of CO2 annually due to the removal of fossil fuel heating.
