Jamie and Pat replaced my old Alpha combi boiler. Replaced most of the gas supply pipe from where it enters the flat because the diameter of the existing pipe was too small. The old boiler had not been condensing, so they replaced the flue and added plume management kit which takes fumes away from my bedroom window. They installed a pump within boiler cupboard to pump condensate water around the kitchen at skirting board/plinth level, into the kitchen sink waste pipe. Jamie explained this would make an occasional humming noise but so far I haven't heard it at all. Installed a wireless thermostat in my living room. Magna cleanse of all the rads. Budget: It was done exactly to budget as in the quote. I had obtained a second quote for installation of a Vaillant combi, which was £1,000+ more. 2nd quote did not need me to clear half of living room and bedroom out. Well worth clearing out for £1,000 difference! First impressions: Jamie was unfazed by all my questions, clearly knew his stuff and calmly explained what was needed. Later I emailed questions and he responded promptly and straightforwardly. He and Pat were polite, tidy and efficient, and disposed of the old boiler straight away. The immediate difference is warmth in every room, and quietness. Am very pleased with the result, they did a brilliant job. Schedule: The day before, Jamie contacted me to delay the work by a day. This was OK for me on this occasion.
