We have used British Gas to service our central heating since 1992. We have consistently found that the BG engineers are excellent. They really know their stuff and are good at their jobs. By contrast, a few years ago, BG started contracting out some of the service work to other plumbers. That was a big mistake. We had to have some work re-done and we complained to BG as we had never had that trouble with BG engineers. Today, we had a BG engineer and he was excellent. So I would say to BG, please just focus on quality rather than convenience or cheapness. I know BG rightly comes in for criticism at times, but when it comes to servicing central heating, our experience has been all good.
