Which? Trusted Trader — independently vetted & approvedUpgrade to an efficient A-rated boiler with a free site survey and honest advice on what actually suits your home — from a Vaillant Advanced Installer and Worcester Bosch Accredited business.
Based in Brentford TW8 — fast response across West London.
Every home is different. We survey your property for free, talk through how you use your heating and hot water, and recommend the boiler that genuinely fits — whether that's Vaillant, Worcester Bosch, Baxi, Main or Potterton.
Your new boiler is installed to current Gas Safe regulations, commissioned and registered, with the system flushed and inhibitor added so your warranty is valid from day one.
Combi, system or regular; the right output for your rads and hot-water demand; the best flue route — it all matters, and getting it wrong means a boiler that short-cycles or can't keep up. We survey your home for free, ask how you actually live, and recommend what genuinely fits, whether that's Vaillant, Worcester Bosch, Baxi, Main or Potterton.
A new boiler is only as good as the system it sits on. We flush the system, fit a magnetic filter, add inhibitor, and install to current Gas Safe standards — then commission, register the warranty and hand over the paperwork. That's what keeps the manufacturer guarantee valid from day one.
In a hard-water area like West London, a magnetic filter and an annual service protect your investment, and a water softener keeps limescale off the heat exchanger for the long haul. Small measures, but they're the difference between a boiler that lasts and one that struggles.
Gas leak, burst pipe or no heating? We're available around the clock.
A straightforward swap usually takes one day. A conversion or relocation typically takes two to three days. We'll confirm the timescale in your free survey.
We install A-rated boilers from Vaillant, Worcester Bosch, Main, Baxi and Potterton. As an accredited installer we can offer extended manufacturer warranties on selected models.
If your boiler is under 10 years old and the fault is minor, repair usually makes sense. Older boilers needing major parts are often better replaced. We give an honest recommendation either way, and the survey is free.
A straight swap is usually a day; a conversion or a move takes two to three. We confirm the timescale at your free survey so there are no surprises.
Yes — removal and responsible disposal of the old boiler is included as standard.
