Which? Trusted Trader — independently vetted & approvedAnnual servicing keeps your boiler safe, efficient and under warranty — and landlords get their Gas Safe CP12 certificates sorted without fuss.
Based in Brentford TW8 — fast response across West London.
Pick a time that suits you and book your annual boiler service in seconds — your booking drops straight into our diary, no phone call needed.
An annual service catches small faults before they become winter breakdowns, keeps your manufacturer warranty valid, and keeps the boiler burning efficiently. That sludge-covered filter in the photo? That's what we pull out of neglected systems — regular servicing and a clean magnetic filter protect your boiler's heat exchanger and pump.
If you let a property, you're legally required to have a Gas Safe registered engineer inspect the gas appliances every 12 months. We handle CP12 inspections and certificates across West London, with reminders when yours is due.
A proper service is more than a glance. We check combustion and gas pressure, inspect the heat exchanger, burner and seals, test all safety devices, check the flue and ventilation, and look for corrosion or leaks — then give you a clear report on the boiler's health, not just a tick in a box.
If you let a property, an annual Gas Safe (CP12) check on every gas appliance is a legal duty. We carry them out across West London, turn the certificate around quickly, and — if you'd like — set an annual reminder so a renewal never slips through the cracks.
Servicing keeps your manufacturer warranty valid, keeps the boiler running efficiently (a furred-up or poorly-set boiler burns more gas), and catches small faults before they become a no-heat emergency. It's also your carbon-monoxide safety check — reason enough on its own.
Gas leak, burst pipe or no heating? Emergencies go straight to the front of our queue. Outside working hours, leave a message or send us a WhatsApp and we'll come back to you first thing.
Once a year. Annual servicing keeps your boiler safe and efficient, prevents breakdowns, prolongs its life and is required to keep most manufacturer warranties valid.
A CP12 (Landlord Gas Safety Record) is the legal certificate landlords must obtain every 12 months from a Gas Safe registered engineer, covering every gas appliance in a rental property.
We inspect and clean key components, run a flue gas analysis, check gas pressure and safety devices, clean the magnetic filter and confirm the boiler is operating to manufacturer specification.
Once a year. It keeps the manufacturer warranty valid, keeps the boiler safe and efficient, and catches faults early.
A service is a full health check of your boiler; a CP12 is the landlord's legal gas safety certificate covering every gas appliance in a let property. We do both.
