SMD Energy is a specialist air source heat pump installer serving homes and businesses across London, Kent and Essex. As experienced heating engineers, we design and fit energy-efficient heat pump systems that cut running costs and reduce your home’s carbon footprint compared with traditional gas central heating.
Our team handles the whole process — from an initial heat loss survey and system sizing, through installation and commissioning, to ongoing central heating services that keep your system running efficiently for years. Whether you need a full central heating system replacement, a heat pump alongside your existing setup, or general fault-finding and maintenance, our local gas and heat pump engineers cover the South East.
As trusted heat pump installers in London and central heating installation specialists in Kent, we help you weigh up a heat pump against a traditional boiler based on your property, insulation and budget, and can advise on grants that may apply.
