We aim to respond within 24 hours across Essex and North London, and often attend the same day for emergencies such as no heating or hot water. See our emergency callout page for more.

We work on all major boiler brands including Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann, Glow-worm and Potterton. Our engineers carry a wide range of parts to fix most faults on the first visit.

Note down the exact error code displayed and call us. Many error codes can help us diagnose the issue before we arrive, allowing us to bring the right parts for a faster fix.

A power flush removes sludge, rust and debris from your central heating system. You may need one if you have cold spots on radiators, noisy pipes, or your boiler seems to be working harder than usual.

A straightforward like-for-like replacement typically takes 4-6 hours. A full system upgrade including new pipework may take 1-2 days.

Signs include frequent breakdowns, rising energy bills, a boiler over 10-15 years old, or repairs becoming increasingly expensive. Our engineers can assess your boiler and give honest advice on repair versus replacement.

We supply and install Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann and other leading brands. We'll recommend the best option based on your home and budget.
