Green Gas have done 3 jobs for me in 2023: a boiler service, a minor plumbing repair and changing a heating zone valve. Udo and his team are transparent on pricing, work cleanly and professionally, and are a pleasure to have in the house. They have also been fair e.g., for the zone valve job, Udo first aimed to repair the valve. When it became clear a day or so later that it was beyond repair, he came straight back to replace it, charging just for the new valve on the second visit.
