Our central heating boiler broke down, we had no heat or hot water and it was very cold weather. We rang round a few people to get a quote but most seemed disinterested or couldn't come for a couple of weeks. John came the next day, gave us a fair price and explained what our options were. We ended up replacing the boiler for a more efficient one, and John came to do it just 4 days later, so we weren't in the cold for too long. he did a great job, fitted an energy efficient boiler and explained everything as he went along. He was very tidy and worked hard to get it all done in a day. Highly recommended.
