We’re based in Patchway and our engineers work throughout Bristol and the surrounding areas, including Bath, Clevedon, Nailsea, Portishead, Weston-super-Mare, Dursley, Yate and Corsham. See all the areas we cover.

As Gas Safe and OFTEC registered engineers, we offer gas, oil and LPG boiler installation; gas, oil and LPG boiler servicing and repairs; landlord servicing and gas safety checks; underfloor heating; and plumbing.

Yes. Work on gas and LPG appliances is carried out by Gas Safe registered engineers, and work on oil-fired systems by OFTEC registered engineers. We’re also Worcester Bosch accredited partners. You can ask to see your engineer’s Gas Safe ID card on arrival. Our accreditations.

We install gas, oil and LPG boilers throughout Bristol and the surrounding areas, including combi, system and regular boilers. We’ll recommend the right one for your home and budget. See boiler installations.

Our engineers will assess your home and talk you through the options so you can make an informed choice. Or answer a few simple questions with our online boiler quote for a recommendation, and compare the boiler makes and models we install.

It depends on the boiler, the work involved and whether it’s moving or you’re changing system, so we give you a clear quote rather than a figure over the phone. Our guide to new boiler costs in the UK explains what affects the price.

A like-for-like replacement usually takes a day. Moving the boiler or converting your system takes longer, and we’ll confirm the timings before the work is booked. Read what to expect in a boiler installation.

As Worcester Bosch accredited partners, we can offer guarantees of up to 12 years on selected Worcester Bosch boilers. Terms depend on the model and include an annual service. See Worcester Bosch boilers.

At least once a year. An annual service keeps your boiler safe and efficient, catches small faults before they become big problems and keeps any guarantee or warranty valid. See boiler servicing.

Usually around 30 to 40 minutes for a gas boiler. Oil boilers take longer because of the extra cleaning and checks. See gas boiler servicing and oil boiler servicing.

If your boiler needs repairs often and they’re getting costly, replacing it with a modern, efficient model is usually better value. Our engineers will always give you an honest recommendation. Read should I repair or replace my boiler?

Typically around 10 to 20 years when it’s properly maintained. Consider replacing it when faults keep coming back and repairs cost more than a replacement. Here are the signs it’s time to replace your old boiler.

Check the pressure gauge, any fault code on the display, that the thermostat is calling for heat and that the power and fuel supply are on. Low pressure is common: here’s how to re-pressurise your boiler. Still stuck? Book a boiler repair.

Don’t use electrical switches or naked flames. Open doors and windows, turn off the gas at the meter if you can, leave the property and call the National Gas Emergency Service on 0800 111 999.

If your rental has gas appliances, you need a gas safety check by a Gas Safe registered engineer every 12 months and a Landlord Gas Safety Record (CP12). We can service the boiler in the same visit. See landlord boiler servicing and landlord boiler cover.

Yes. Low-profile warm water systems can go on top of an existing floor, and electric systems suit smaller rooms such as kitchens and bathrooms. See underfloor heating installations.

Yes. Our team fixes leaks, fits radiators, valves and showers, and repairs pipework, as well as looking after your boiler. See plumbers in Bristol.
