Services
Boiler Service
Our comprehensive boiler servicing includes safety checks, component cleaning, gas pressure testing, and carbon monoxide detection. Engineers perform visual inspections for corrosion, internal part examinations, and efficiency assessments. Regular maintenance extends boiler lifespan while identifying potential issues before they escalate. All services conducted by Gas Safe registered professionals with full system diagnostics provided post-service.
Boiler Installation
We specialise in combi boiler installations from leading brands including Baxi, Worcester, and Vaillant. The process includes system assessment, removal of old units, and efficiency optimisation. All installations include 5-10 year manufacturer warranties with energy efficiency improvements typically reducing annual bills by 30%. Smart thermostat integration available for enhanced temperature control.
Boiler Repair
Available 24/7 for urgent heating failures, our repair service addresses common issues like thermostat faults, pressure problems, and component failures. Engineers carry extensive spare parts inventories for same-visit resolutions. Emergency call-outs prioritised with typical response times under four hours during standard operating hours.
Smart Thermostats
We install programmable smart thermostats enabling remote temperature management via smartphone apps. Systems feature geolocation tracking, weather adaptation, and energy usage monitoring. Compatible with existing heating systems, these controls typically reduce energy consumption through automated scheduling and zone-specific temperature management.
Powerflush
Our powerflush service removes sludge and limescale buildup from central heating systems using high-pressure chemical solutions. The process restores system efficiency, reduces boiler strain, and extends component lifespans. Includes magnetic filter installation and corrosion inhibitor application for long-term protection against recurring deposits.
