I had a very disappointing experience with UK Gas Plumbers. At first, things appeared professional: they asked for photos of the installation area and provided a quote based on that. I accepted the quote informally and followed up with a call to ask which boiler model they intended to fit, as I wanted to ensure we aligned our flow and return correctly in advance. Essentially he responded was saying that only an idiot would want to get the flow and return aligned correctly in advance. His tone was really unexpected and unnecessarily condescending. I’m always very polite and helpful, he could have responded in the same way regardless of his answer. Then, just two days before the scheduled work, he asked for a video of the same location we had already photographed — and then increased the price by about 30% with no explanation. He had not previously asked for a video. When I raised concerns about this last-minute change and how we were being treated, I received no response at all.
