St Peter Mancroft Church in Norwich city centre has dramatically reduced its carbon footprint and energy use by replacing its entire interior lighting system, installing OCHSNER heat pumps as well as batteries and solar panels. Through this work, the church expects to see an 84% reduction in emissions by saving 60 tonnes of CO2 each year. St Peter Mancroft is now recognised by The Church of England as a Demonstrator Church as an example for all churches striving to meet the CofE's Net Zero 2030 ambition
