Services
Boiler Installation
We specialise in installing high-efficiency Worcester Bosch and Vaillant boilers, ensuring reliable heating and hot water systems. Our engineers provide expert advice on model selection, handle all pipework and controls, and offer warranties up to 12 years. All installations comply with Gas Safe standards and include system flushing to maximise efficiency and longevity.
Gas Safety Checks
We conduct annual gas safety inspections for rental properties, issuing Landlord Gas Safety Certificates as required by law. Our checks cover all gas appliances, pipework, and ventilation to ensure compliance and tenant safety. We also offer combined boiler servicing during inspections to maintain system efficiency and identify potential issues early.
Boiler Servicing
Regular boiler servicing prevents breakdowns and extends system lifespan. Our comprehensive service includes combustion analysis, flue gas testing, component inspection, and system pressure checks. We use manufacturer-recommended parts and provide detailed reports to ensure transparency. Annual servicing also maintains warranty validity for most boiler brands.
Emergency Repairs
We offer urgent boiler and heating repairs seven days a week, including evenings and weekends. Our engineers carry common replacement parts to resolve issues promptly, from pilot light failures to complete system breakdowns. Emergency call-outs include a free initial assessment, with no additional charges for out-of-hours service.
Power Flushing
Power flushing removes sludge and scale from central heating systems, improving efficiency and preventing boiler damage. We use high-velocity water flow and specialist chemicals to clean radiators, pipes, and heat exchangers. This service restores even heat distribution, reduces energy bills, and extends system lifespan, particularly for older installations.
