Northern Gas Heating (NGH) recently came to put in a new Boiler and shower and a couple of radiators. Firstly, the day works were scheduled to begin, 'NGH' rang us to cancel the job on the basis boiler was not delivered. Very lousy as should have done checks. Second issues, works eventually scheduled again, on day of works my husband received a call from 'NGH' to say he would need to sign some Completion of Works agreement. My husband stated he will only sign when if satisfied with job carried out. He was then told, agreement must be signed or works won't be carried out but we should have no problem as 'NGH' workers are very professional and know their job. Works eventually carried out. To date, no heating, no hot water, leaking shower from the pipes. Also, they have somehow managed to effect the toilet so when it flushes, there is no water to flush away waste. Our whole house is now affected. Called them, wrote a letter to 'NGH' company, same workers came back to us arranging for the same person to rectify job even though we wanted different people. You would have thought they would want to rectify mistakes and extremely shoddy work as soon as possible, not 'NGH' despite our concerns, they could told us works to fix problem could only be towards the end of this month (October). We have read some bad reviews about 'NGH' but thought they must be few and far between. Now it has happened to us. We would say to anyone reading this, don't take the chance with 'NGH'. I have never experienced a company with such bad customer service and the worst ever piece of professional (if you can call it that) work done. Ofgem, if you are reading this look into 'NGH'. They need to be regulated as they are providing nothing more than a scam to customers. They take your money and after that, put up with what you get from them. I am absolutely disappointed and won't recommend them to anyone ever.
