Just had a solar installation done by these guys. All of the people involved (electricians, scaffolders, panel fitters, etc.) were polite and professional; the install was arranged through OVO and their people onsite were also great. When the planned approach was determined to be slightly wrong -- two strings where one was more appropriate -- they very quickly agreed to the needed changes and got the design updated. Very professional work that is neat and tidy, with my need to work from home being taken into account -- power was only off for about 20 minutes. Scaffolding went up on Monday, installation was done on Wednesday and Thursday, Scaffolding removed on Friday. Overall very pleased and would happily have more work done by Gas Tech Wales.

Initial contact with the office was good. However our straight forward Solar Panel (on behalf of EON) install started off with the first team turning up at 11am. After running out if time, they left with a second team returning 3 days later. The first team, left the electrical work that had to be installed in a downstairs bedroom, in a messy state. Little consideration was given to the appearance as the newly painted room that was left very dirty and the Isolator and Control box was fitted a distance away from where it could have been fitted. We now have to appoint a carpenter to build a box around the boxes. The second team arrived early enough and completed the work fine. However, I felt that more time could have been spent showing us around the equipment to explain how it all worked and what to do with the software perhaps. An update. The system did not work correctly from installation and after speaking with the Battery/Inverter manufacturers, it was found the system was incorrectly fitted, hence the reversed readings. After a few weeks, they returned to repair, only to have damaged one of the sensor wires, requiring yet another visit. After over a month, it is now working fine.

Gas Tech came to my home in October 2020 to fit a boiler on behalf of Eon Energy. Whilst fitting the boiler the engineers melted a water pipe and an electrical cable whilst joining new pipework to old (a protective gauze should have been used) . This has caused a water leak spanning over 14 months which started to come through in December 2021. Currently I have over £1500 worth of damage still not attended too in my kitchen (see photos). Neither Gas Tech or Eon want to address the problem now, neither are answering their emails or phonecalls and a formal complaint has been rejected by Eon. Gas Tech are for some reason saying their not responsible for the work. Stay very clear of this company if you want work done by them. Their nothing more than a bunch of cowboys that think it's acceptable to come into someone's home, cause extensive damage and walk away. If looking for a boiler stay clear of Eon, as aftercare service is non existant. The matter is being taken further now through the ombudsmans service and court action.

Excellent company. I have been using them for a number of years, initially to install a new boiler and since to carry out it's annual service. Their engineers are always very professional, helpful and explain everything in layman's terms. Plus, they offer real value for money compared to some more nationally recognised household brands.

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.
