Great pre sales service, and instillation great. Even took everything away ols water cylinder, boiler and water tank! Only issue is they need to come back as we can see small holes of daylight, as pipes outside just need a bit more sealer. Overall very good service. Also just waiting to be contacted to check all is ok, and details of the monthly service plan they offer, please!

GWE are an excellent company who deliver high quality customer service and professionally install heating products. Scott and his team Jamie and Cullum, know exactly how to deliver customer requirements to a very high level. For my new boiler and new radiators installation the work was completed efficiently and to a high standard. The team are very focused on getting the job done and meeting expectations from start to finish, including quotes, billing and customer support. I would high recommend GWE as you rarely come across a trade company of such quality..

Fantastic Boiler Service – Highly Recommend GWE! I had my annual boiler service done by GWE and I couldn't be more impressed with the experience. The engineer arrived right on time, was friendly and professional and clearly knew exactly what he was doing. He explained everything he was checking and even gave me a few helpful tips to keep the system running efficiently. The service was thorough and tidy and I really appreciated the attention to detail. It’s clear GWE takes pride in their work and values their customers. Booking was easy, communication was great throughout and the pricing was very fair for the quality of service. Highly recommend GWE for anyone needing boiler servicing or heating support—reliable, efficient, and a pleasure to deal with!

I've used GWE for boiler servicing and minor plumbing work for several years. Nice people to deal with, always prompt, and they leave things clean and tidy. Their engineer spotted a problem with our new boiler that had been causing central heating failures and had not been noticed by the original installer. (Now fixed under warranty). Recommended.

New boiler fitted, old one removed and flush of our heating system carried out today. Competitive price and very impressed with our installer who I unfortunately didn't get the name of. He was friendly, polite, conscientious, tidy, knowledgeable and very professional. Fantastic representative of his company. Tidied as he went, lay dust sheets, wiped his feet in the house and worked very hard despite this hot weather and having to test have the heating on for testing! Fully explained all the work he had carried out after he had finished, walking me through the house explaining bit by bit. Very happy with the level of service I have received from this company as a whole, from arriving to provide us a quote, to the correspondence from all their team leading up to the installation. And the installation itself. Would thoroughly recommend and so lovely to find great trades people. Thank you GWE.

We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
