"Avoid Gast Tech Wales"

We have a leak in the piping system after an installation of a new boiler (through E.ON) done 4 weeks ago. Leak is not their fault, but they came back to assess the repair straight away. Engineers are good and competent but the back office is just ridiculous. Since then, I have chased multiple times to get a quotation (even through E.ON). Despite saying they were going to send a quotation the same day, NOBODY sent us a quotation and they left us with no heating nor hot water in the coldest time of the year. Umbelievably unprofessional behaviour. Avoid this company

"Boiler replacement"

Friendly and efficient staff fitted new boiler would highly recommend this company

"Had. sources heat pump installed …"

Had air sourced heat pump installed last winter. The owner of GT failed to measure my airing cupboard/the boiler would not fit into the cupboard. Consequently I was without any heating for 10 of the coldest days of the winter and also had to have the obtrusive controls sticking out into my bedroom rather than in the cupboard due to lack of space).The technicians were absolutely wonderful (though constantly frustrated) and had the additional inconvenience of having to put the pump in the loft.
The technicians were very careful about not making a mess but GT’s electrician ruined my carpet.
I am still awaiting radiator valves and compensation for my carpet- both promised for 8 months now.
Basically I think this company would benefit by the top manager and electrician developing better communication skills.

"Despite 32C teperatures, 15 solar panels installed and working."

The weather was unbelievably hot on the roof, locally recorded at 32C. The team of three, an Electrician and two roofers worked tirelessly throughout the day to install 15 panels on the South and East facing sides.
I would use again and recommend Gas Tech (Wales)

"All the teams of workman extremely…"

All the teams of workman extremely friendly, yet professional and polite. A real asset to the company. But let down by the company’s organisational skills. Had to take two and a half days off work for a days job!

"Gas Tech Wales Eon Solar contracts…"

Gas Tech Wales have a contract with EON Solar to put solar panels and batteries into businesses and houses. The lead team arrived, scaffolders and deemed the job too hard for them. I had a meeting a couple of days later, sorting access on a Saturday in the hospital next door. A sensible solution and made it easier for them to install. The boys then refused to work a Saturday due to Rugby Internationals and Bank Holidays. Totally unhelpful in the office, even though a solution was there. Teams work together to sort problems but unfortunately they all work for themselves.

"Pleased with the service"

They just Fitted my new panels and stored battery, all works fine
Surprised how much power they produce , app works great
They always answer phone when you call

"None existent customer service"

On friends' recommendation we had solar panels fitted by this company. No problem doing the job...the blokes turned up on time and did the business on 4th January. However there was absolutely no, zilch, instructions about the workings of the system, which is the least you'd expect for £8.5k worth of hardware. I had to call them a few days later to see if the system was up and running and got instructions over phone to connect it to app. I then had to call them to get system connected to grid for feed-in, as they seemed to have gone to sleep on the job.

A few weeks back I had to get back in touch with them as the app had disconnected from system…3 times I called but am still waiting for return call. I had to get a friend in to sort it.
Our 4.8khw battery has not charged to more than 10% since its installation – 10 weeks ago- despite the fact our panels are producing twice the amount of electricity we are using in the house. I emailed a few days back to report this….still haven’t heard from them. Yesterday the app informed me that the battery was 18% full, which went to 19% and then instantly dropped back to 10%. At this point half of the electricity in the house went off. I saw a trip switch had gone to off and turned it back on …that then blew again within minutes. Eventually I turned it back on again and it appears to be ok now. Whether the battery situation is cause or correlation, I don’t know. However, my battery is not delivering what it is supposed to do.

Dreadful customer service

"All the Gas Tech installers were a joy…"

All the Gas Tech installers were a joy to have on our property except for one electrician whose attitude, manner, and general demeanor were offensive to me and my wife. He wanted to walk on our light beige carpeted staircase in his work shoes until I told him he could not and that I wanted the number of his head office. I was asked to sign three separate documents that were not shown to me. I still have no idea what I signed. This is highly irregular. The Givenergy battery was mounted crooked and the next day when some errors in the electrical connections had to be rectified, I pointed this out to their staff that came out and an attempt was made to straighten the inverter. This electrician did not even have pride in how the labels were placed on the inverter and battery. They were put on crooked. We got the impression that he thought he was doing us a favour. Really disappointed. Because of this one offensive individual, I would have great difficulty in recommending Gas Tech. Finally, they did not link up my Zappi charger even though I offered to call the Zappi engineer to explain to them what needed to be done. I’m not sure they know what to do. This is not a unique request as the internet is full of what the correct procedure is to link my Zappi charger. No one explained how the software works nor what my preferences are as I installed the system to charge my car via solar only. Sad how one individual can undo the work of his colleagues and employer by poor attitude. I cannot recommend Gas Tech Wales to anyone.

"Boiler Installation"

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.
