Company left me with a faulty part which was fitted in July 2018. I paid over £200 for a visit, including valve itself. Leak outside of the house re-appeared after few months. Issue was reported. Engineer came in and confirmed it was a problem on their part (but said someone else was to come in and fix it). Yet, I had to pay additional £90 'deposit' for his visit, luckily received £90 refund. As a follow up, I was said that 'part was ordered in and someone is to come to fix it' in Dec 2018, which never took place. Every time I phone in since then to follow up - no-one is ever able to assist. All that happens every time: I am promised a call back, and no-one ever does. I now reported this matter to CIPHE. I now am facing Health and Safety issues due to having a leak outside as a result of their lack of care (with -temperatures and it turning into ice). I paid £200 for services which were of unacceptable quality. Company offers a year guarantee on services/ parts - this is why I did not mind paying higher prices, but do not believe it, it is just another empty promise. I do not recommend the company, and I regret not reading some reviews on their website before ordering them.
