Case Studies
Real-world heat pump and renewable energy case studies showing how low-carbon technologies perform in UK homes, businesses and public buildings.
Each case study explores a completed project, from air source and ground source heat pump installations in off-gas-grid homes and listed buildings to solar PV, battery storage and EV charging systems for commercial sites, social housing and new-build developments. We look at system design, heat loss calculations, product selection, installation challenges, running costs, carbon savings and customer feedback, so you can see what worked and why.
These installation examples are written for installers, specifiers, housing providers, architects and homeowners who want evidence that heat pumps and renewables deliver in practice, including in older, hard-to-heat properties.
