One of our members, David Groome in Wood Vale N10, has just replaced his boiler through our Low Carbon Buying Group. Here’s what he said ” We have just had our central heating boiler replaced by John Sleeman, who was recommended to us by the Muswell Hill Sustainability Group (MHSG). I am happy to say that John did an absolutely first class job. It was clear from the outset that he has the knowledge and experience to overcome any problem he encountered, and he carried out the work in a very competent and thorough manner. We were very impressed with all of John’s work, and his prices were also very reasonable. It may be possible to find someone who would offer to do the job slightly more cheaply, but they definitely will not do the work as thoroughly. John is also a very pleasant guy to have around the house, keeping noise and intrusion to an absolute minimum. If you are thinking of replacing your boiler then we would recommend John Sleeman without the slightest hesitation.
