Services
Boiler Servicing
Annual servicing of oil-fired boilers ensures safety, efficiency, and compliance. Our engineers perform CO2 and efficiency testing, component inspections, and adjustments to optimise performance. Regular maintenance prevents carbon monoxide risks and reduces fuel costs by maintaining peak operational efficiency.
New Boiler Installation
Professional installation of high-efficiency condensing boilers tailored to property requirements. We handle both new-build and replacement systems, including programmer and motorised valve integration. Our solutions prioritise energy efficiency while complying with current environmental regulations and manufacturer specifications.
Power Flushing
High-velocity water flushing removes sludge and debris from central heating systems. This process prevents boiler damage during upgrades and ensures optimal performance of new installations. We use Kamco Clearflow CF30 equipment to maintain system integrity without causing physical damage to pipework or components.
Tank Installation
Compliant installation of single-skinned and bunded oil tanks with Watchman Sonic monitoring systems. We replace outdated steel tanks with durable plastic alternatives, ensuring environmental safety and adherence to current legislation while providing reliable fuel storage solutions for residential properties.
Range Cooker Re-enamelling
Cosmetic refurbishment of Aga, Rayburn, and Stanley ranges using professional re-enamelling techniques. We replace damaged components and upgrade solid fuel systems to vapourising or pressure jet models, extending appliance lifespan and improving functionality at a fraction of the cost of new units.
