Quality work done with care.
QAS have done two lots of work for us. One a boiler removal/replacement from an ancient tank system, to a modern combi boiler, involving resituating the boiler and upgrading the pipework. Second was a heat loss calculation, which made a convincing argument for swapping and upgrading most of the radiators in the property. Prices were competitive, work was of an excellent quality and communication was clear and articulate. They dealt with several significant obstacles emerging from the age of the property, existing infrastructure, and a dash of modern software issues from "smart" technology. All discussed, explored and resolved in a satisfactory manner. Pleasure to meet someone who is genuinely passionate about their trade (self-proclaimed heat geek), generous with their advice on ongoing works, and helpful to a tee in presenting solutions to issues. Timelines provided we're often on the more optimistic side, but as long as you are reasonable and realistic in planning and allow for remedial or where issues arise, you're not going to be disappointed with any of the work done. Would happily recommend for anyone looking for a professional who clearly takes pride in their work.
