A boiler that won't fire up, keeps cutting out or is simply past its best doesn't have to mean days without heating or hot water. HGH Plumbing & Heating installs and repairs boilers across Barnet, Brent, Harrow and North London — and as a Baxi approved installer, we fit reliable, efficient boilers backed by strong manufacturer warranties.
New boiler installation
We help you choose the right size and model for your home, remove the old unit and install the new one cleanly, with everything tested and certified by a Gas Safe registered engineer (no. 947635). Ask us about upgrading from an old conventional system to a modern combi.
