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.
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? We're available around the clock.
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.
