Avoid avoid avoid! For months now I have been trying to get in contact regarding dangerous work they completed. My gas boiler was wired completely wrong which caused the pcb board to blow. I was left with no paperwork and the boiler was not even condemned! Gas safety have been informed. The rest of the work is faulty - air vents do not work and the smart plugs for the radiators now when I use them on the app turn on the heating for different rooms so I’ve no idea what’s happened. I’m in the process of going to court as they cannot be allowed to get away with this. They left myself and my children in a dangerous situation. They then claimed on my boiler warranty without my permission which means my account is now chargeable! I wish I had never used this company I do not know how they are still operating. They should not be allowed to.

Avoid this company. I was asked repeatedly (over 10 times) to provide information about my elderly parents’ property. I supplied the requested details on three separate occasions, yet the company still failed to carry out the work they had promised. Months later, I began receiving WhatsApp messages requesting extremely sensitive personal documents belonging to my parents, including copies of their passports, birth certificates, and marriage certificate. This felt completely inappropriate and unnecessary. Some time later, representatives turned up again wanting to install external wall cavity insulation. I explained that this had already been done and asked them to leave. After I left, a workman returned to my parents’ home and demanded to see their passports, which unfortunately my mother felt pressured into showing. To make matters worse, emails sent by the company stated that my parents had been provided with a new boiler, which was completely untrue and was never installed.

DO NOT USE! If you have a nice home and don’t want it trashed by terrible workmanship don’t go with these people! They never turned up for the first appointment. When they came the second time they turned up at 4pm and stayed late into darkness. Wearing flip flops whilst doing manual labour up ladders. My guess is they setup to just try and claim some of the government contracts. They have no experience and are cowboys. They left brick dust everywhere and there making good looked like Stevie wonder did it. When someone then came to quality assure the work it failed miserably, it turns out they installed the wrong fan in the bathroom and didn’t bother in the kitchen or upstairs bathroom at all. Also no electrical sign off cert was issued. They installed vents in the windows which didn’t work as they never cut the gaskets out to allow for airflow. They were made to re-attend which I didn’t really want but they sent a threatening email. They eventually came back but on the wrong day as they can’t read a calendar and tried to put right the mess. I had to go to work so couldn’t stay but my partner did. Once I returned I checked the vents to which 3 were broken and fell down as soon as I opened the window. I emailed Britain energy as this is beyond a joke and I offered to install the vents myself as I don’t want them back. They sent 2 vents out and refuse to send a 3rd as apparently it’s not possible to break 3….. Absolute clowns. Keep well clear.

Wouldn't use company. Insulation Staff spoke limited english and when i asked a question they spoke amongst themselves in their own language , then were constantly on their phone on loud speaker in their own language. Felt under pressure as i stated i didnt want one of the services the tricke vents as they were not needed on all windows and they were wanting to place them on the side of the window not the top. They said i couldnt get insulation and boiler , then stated we have come all the way from blackburn when i said i think i will leave it . I eventually gave in and had boiler men come the next day again english was limited and spoke in their own language . Gave me a few minutes guide on the app to use for the radiator valves and left me to put some of them to put on myself !! The pressure in the boiler has gone twice in the 2 days ive had it and nobody has come back to me about issues after chasing it a number of times!!
