A difficult job replacing a very old boiler, but Gadi was extremely professional, tidy and helpful. Many thanks.

Outstanding service at an affordable rate. The engineers demonstrated expertise and arrived promptly as promised. They worked diligently late into the evening to finish the job on the same day and tidied up afterwards.

Great service. Matt the engineer came quickly and helped diagnose a complex wiring problem for my central heating system. You can see from the attached photo how many wires needed to be looked at. An hour later I have hot water, underfloor heating and central heating. I found Matt to be knowledgable and very capable. Thanks so much guys. Really appreciate the work. Highly recomended.

Report
After a challenging couple of days with a blocked kitchen sink and a grumbling boiler (so no hot water or central heating), I finally called Gas Weiss. Within ten minutes, (not the two hours guaranteed by the office), two highly competent plumbers arrived and sorted both problems out, which turned out to be inter-related . They were clean, tidy, reassuring and knowledgeable. I am very happy to recommend this company.
