Horsham is one of West Sussex's most desirable market towns, known for its historic Carfax and mix of Victorian terraces, inter-war semis, and modern developments. The town's wide variety of property ages means our engineers regularly work on everything from traditional gravity-fed systems to the latest high-efficiency combi boilers.
We cover central Horsham, Roffey, Broadbridge Heath, Southwater, and the surrounding villages. As a busy market town with a growing population, we prioritise rapid response to keep homes warm and hot water flowing.
We supply and install all leading boiler brands at competitive prices. We'll recommend the right boiler type and output for your home in Horsham – whether that's a combi, system, or heat-only boiler – based on your property size, hot water demand, and budget.
Every new boiler installation includes: removal of the old boiler, full system flush with inhibitor, installation and commissioning of the new boiler, new thermostat and controls where required, and all Gas Safe paperwork. We register your new boiler warranty with the manufacturer as standard.
