Services
Boiler Installation
We install energy-efficient boilers from leading brands like Viessmann and Ideal, ensuring compliance with Gas Safe standards. Our engineers provide tailored advice to select the right boiler for your property size and needs. With a 12-year warranty available on Ideal Max models, we guarantee long-term performance and safety. The process includes a site assessment, removal of old units, and seamless integration with existing systems. Our team prioritises minimal disruption, completing installations efficiently while maintaining clear communication throughout.
Boiler Servicing
Regular boiler servicing ensures safety, efficiency, and warranty validity. Our Gas Safe engineers conduct comprehensive checks, including flue analysis, pressure testing, and component inspections. We identify potential issues before they escalate, reducing breakdown risks. The service includes cleaning internal parts, checking gas pressure, and providing a detailed report. Landlords benefit from compliance with legal requirements, while homeowners enjoy lower energy bills and extended boiler lifespan through preventative maintenance.
Central Heating Installation
We design and install custom central heating systems to improve home comfort and energy efficiency. Services include radiator upgrades, underfloor heating, and smart thermostat integration. Our engineers assess property requirements to recommend optimal configurations, ensuring even heat distribution. Upgrades often reduce energy bills by enhancing system efficiency. We also offer powerflushing to remove sludge, extending system longevity. All installations comply with building regulations, with a focus on minimising disruption during the process.
Smart Thermostats
Smart thermostat installations enable remote heating management via smartphone apps, improving energy efficiency and convenience. Compatible with existing boilers, these systems allow scheduling and adaptive learning to reduce waste. We install leading brands like Hive and Nest, ensuring seamless integration. Customers benefit from real-time energy monitoring and cost savings. Our engineers demonstrate usage features, ensuring clients maximise the technologys potential while maintaining system compatibility and performance.
Powerflushing
Powerflushing restores heating efficiency by removing sludge and limescale buildup. Using high-velocity water and specialist chemicals, we clear blockages to improve radiator performance and boiler longevity. The process includes descaling, inhibitor application, and debris removal. Ideal for systems with cold spots or rising energy bills, it prevents costly breakdowns. We assess system condition beforehand and provide post-service maintenance advice to sustain results, ensuring long-term reliability and efficiency gains.
