Services
Boiler Installation
We specialise in condensing boiler installations for improved energy efficiency. Our Worcester Bosch accredited engineers ensure modern systems achieving over 90% efficiency, potentially reducing annual heating bills by 30%. All installations include powerflushing recommendations and magna clean filter fitting for long-term reliability.
Gas Safety Inspections
Certified Gas Safe engineers conduct comprehensive appliance inspections. Services include pressure testing, flue gas analysis, and ventilation checks to meet legal requirements for landlords and commercial properties. We provide Landlord Gas Safety Certificates (CP12) and commercial gas main certifications.
Powerflushing
Our powerflushing service removes 95% of system sludge and scale buildup. This restores heating efficiency, reduces fuel consumption by up to 25%, and extends boiler lifespan. Recommended for existing systems during boiler replacements or when experiencing cold radiators and boiler noise.
Renewable Energy
We integrate solar thermal systems, ground source heat pumps, and air-to-water heat pumps with existing heating infrastructure. Our experts provide tailored energy-efficient solutions that reduce carbon footprints while maintaining heating performance for domestic and commercial properties.
Commercial Heating
Specialist installations for commercial premises exceeding 70kW gas input. Services include warm air heaters, radiant tube systems, and complete plant room installations. We offer maintenance contracts and safety certifications for hotels, schools, factories, and commercial kitchens.

Left phone message once for quote. Another time filled in their contact form to request a quote for boiler servicing. They didn't have the courtesy to respond on either occasion.

Terrible communications and poor work. Called another plumber and they fixed the issues pretty simple. Musson hadnt even done a basic service.

We chose Mussons to install our new boiler because of how much a of nice chap Andy is and his excellent and friendly communication. Our task was a tricky one (it's not your typical house) but Andy was patient with us and did an outstanding job. The copper pipework was art! A true craftsman.
