Services
Central Heating Installation
We design and install custom central heating systems tailored to your property's requirements. Our Gas Safe engineers assess your home's heating needs and recommend efficient boiler and radiator configurations. All installations include a free quotation, manufacturer warranties, and energy-saving advice to reduce long-term running costs.
Boiler Servicing
Regular boiler servicing ensures safe, efficient operation and extends equipment lifespan. Our engineers perform comprehensive checks on gas pressure, combustion efficiency, and component condition. We service all boiler types including combi, system, and conventional models, providing detailed reports and maintenance recommendations.
Power Flushing
Power flushing removes sludge and debris from central heating systems to improve efficiency and reliability. This process restores even heat distribution, reduces noise, and prevents breakdowns. We use professional equipment to clean pipes and radiators thoroughly, with visible results and lasting performance improvements.
Gas Safety Checks
We conduct thorough gas safety inspections to ensure compliance and occupant safety. Our checks cover appliance operation, flue integrity, and gas pressure. Landlords receive detailed safety certificates as required by law, with records maintained for two years as proof of compliance.
Landlords' Certificates
We provide legally required annual gas safety certificates for rental properties. Our engineers inspect all gas appliances and issue documentation within statutory deadlines. Landlords receive copies for tenant records and regulatory compliance, with reminders available for future inspection scheduling.
