Services
Boiler Servicing
Regular boiler servicing ensures safe, efficient operation and extends system lifespan. Our Gas Safe engineers perform comprehensive safety checks, combustion analysis, and component inspections. Annual servicing helps maintain manufacturer warranties and reduces breakdown risks, particularly for older systems. Homeowners benefit from improved energy efficiency and lower heating bills.
Boiler Installations
We install energy-efficient gas, LPG, and oil boilers from trusted brands like Worcester Bosch and Vaillant. Our team assesses property needs to recommend optimal boiler types, including combi, system, and regular models. All installations include Gas Safe certification, manufacturer warranties, and clear post-installation guidance for maximum system performance.
Emergency Plumbing
Our 24/7 emergency service addresses urgent plumbing issues including burst pipes, heating failures, and severe leaks. Fully equipped engineers respond promptly across Mid Sussex, prioritising damage prevention and rapid system restoration. No call-out fees apply, with transparent pricing for all emergency interventions.
Powerflushing
Professional powerflushing removes sludge and debris from central heating systems. Using high-pressure equipment and chemical cleaners, we restore circulation efficiency, eliminate cold radiator spots, and reduce boiler strain. Most systems see up to 40% improved efficiency, with recommended intervals of 10-15 years or before new boiler installations.
Gas Safety Certificates
We provide CP12 gas safety certificates for landlords, covering boilers, cookers, and fires. Our engineers conduct pressure tests, flue safety checks, and appliance inspections. Digital certificates with photographic evidence are issued immediately, with annual reminders available to maintain compliance for rental properties.
