Services
Boiler Service
Our comprehensive boiler servicing includes safety checks, component cleaning, gas pressure testing, and carbon monoxide detection. Engineers perform visual inspections for leaks or corrosion, clean critical parts like heat exchangers, and verify safety device functionality. Regular servicing extends boiler lifespan, maintains warranty validity, and ensures safe operation while improving energy efficiency through early fault detection.
Boiler Installation
We specialise in combi boiler installations with A-rated energy efficiency. Our process includes system assessment, boiler selection from leading brands, and complete installation with old unit disposal. All installations include 10-year warranties, magnetic filter fitting, and system efficiency optimisation. We handle LPG systems, unvented cylinders, and provide smart thermostat integration for enhanced control.
Emergency Repairs
Available 24/7 for urgent boiler failures, our rapid response service prioritises same-day repairs. Engineers carry extensive spare parts inventories to resolve 90% of issues immediately. We handle thermostat faults, pressure issues, and component failures while providing clear cost breakdowns before work commences. Emergency call-outs cover North Tyneside and surrounding areas within 2-4 hour response windows.
Powerflush
This process removes sludge and limescale buildup using high-pressure chemical flushing. We employ Kamco CF90 equipment to restore system efficiency, typically completing residential jobs in one day. The service includes inhibitor treatment, magnetic filter installation, and BS7593 compliance certification. Powerflushing reduces fuel bills by improving heat transfer and prevents premature boiler failure from internal corrosion.
Landlord Services
Specialist packages for rental properties include annual gas safety checks, boiler servicing, and Legionella risk assessments. We manage compliance documentation, provide tenant communication, and offer multi-property discounts. Our service plans cover statutory requirements with automatic reminders and priority emergency response, ensuring landlords meet legal obligations while maintaining tenant comfort.
