Services
Boiler Servicing
Regular boiler servicing prolongs appliance lifespan by identifying early faults. Our Gas Safe engineers perform flue-gas analysis and safety checks, ensuring compliance with annual legal requirements for landlords. Servicing maintains efficiency and prevents unexpected breakdowns.
Gas Safety Inspections
We conduct comprehensive gas safety inspections for tenanted properties, examining boilers, cookers, and flues. Our certified engineers identify leaks and ensure appliances meet Gas Safe standards, providing landlords with legally required documentation.
Central Heating Installations
From radiator replacements to full system installations, we design efficient heating solutions tailored to property needs. Our team handles pipework, boiler integration, and system balancing to ensure optimal performance and energy efficiency.
Powerflushing
Powerflushing removes sludge buildup from pipes and components, restoring water flow and preventing boiler overheating. This service resolves temperature fluctuations in combination boilers and extends system longevity through thorough internal cleaning.
Kitchen Plumbing
We specialise in kitchen plumbing installations using durable copper pipework. Services include tap fitting, dishwasher connections, and waste pipe repairs, ensuring watertight, code-compliant solutions for residential and commercial properties.
