A reliable heating and hot water system is essential for every home and business. At The Watkins Hamilton Group, we provide professional boiler installation, replacement, servicing, and repair services across Surrey, Sussex, Kent and London, helping to keep properties warm, efficient, and comfortable throughout the year.

Our qualified heating engineers work with leading boiler manufacturers to install high-performance systems that deliver dependable heating while helping to reduce energy consumption and running costs. Whether you’re replacing an ageing boiler, upgrading to a more efficient model, or installing a completely new system, we can recommend the right solution for your property’s requirements.

Regular servicing plays a vital role in maintaining efficiency, extending equipment lifespan, and identifying potential issues before they become costly repairs. Our comprehensive servicing packages help ensure your boiler continues to operate safely and efficiently while maintaining manufacturer warranties where applicable.

In addition to boiler installations and servicing, we also undertake heating system upgrades, radiator replacements, smart heating controls, magnetic filtration, power flushing, and hot water cylinder maintenance. Our team can diagnose and repair faults quickly, helping to minimise disruption and restore heating and hot water as soon as possible.

We pride ourselves on honest advice, transparent pricing, and high-quality workmanship delivered by experienced professionals. Every installation is completed to current industry standards, with customer satisfaction and long-term reliability at the heart of everything we do.

From annual servicing to complete heating system upgrades, The Watkins Hamilton Group provides heating solutions you can depend on.
