I had to unfortunately use this company as the insurance company I was dealing with put them in place. They had to replace my heating system due to bad weather earlier in year. The quality of their work was dreadful lots of issues but one that stunned me was when they replaced a radiator and thought it was OK to.get the wrong size and put it in which overlapped the door . Luckily I stopped them before it went in. It took them months to get any repair done and when they finally did the pipes they replaced are half plastic half bent half not straight, radiators sticking out and reconditioned fit for the scrap heap.
Worst customer service I've ever had and rude and incompetent office staff.
Please do yourself a favour research them and make sure you are there to watch them all the time do not leave them alone in your house .
