Worst company I've ever dealt with. I am a landlord with a substantial portfolio and had to use them as my usual gas Safe Engineer was unable to make it. Their Engineer did absolutely nothing. All he did was pointed out a bunch of faults that did not exist then when asked to fix it he said he first has to physically disconnect the gas supply. He waited for a couple of hours to have national grid come in and disconnect it. Charged us for the time and left. Later on the company contacted my tenants directly and said we were intentionally putting in a dangerous situation. This company and its people are the very definition of cowboys. Avoid at all cost.
