What Our Customers Say
★★★★★
From start to finish, a very professional company. I had a new boiler fitted after a very cold New Year’s Eve. I was kept in the loop at every stage of the process; deciding on budget, convenience and quality and finally the timeline. I would definitely use them again. I am so pleased to have hot water and heating again.

Harmeen and his team were very helpful throughout the renovation of my 2 bed flat. Changing the boiler, radiators and pipe work. He did things to a high standard and was very quick in responding to any extra requests I made. I’d definitely recommend

★★★★★
Harmeen and his team did a marvellous job changing my new boiler on the 16/2/26.
He came on time and the job was completed the same day. I’m extremely impressed with the work carried out.
I will recommend his company Gx7 Ltd to anyone.
