Good service from competent heating engineers.
Customer Service
I called Mannix to attend a faulty Worcester Combi boiler for a tenant, because they are on the recommended list of the manufacturers. The fault turned out to be a jammed diverter valve which they freed.They came very promptly, did the work without any fuss, the boiler has remained in operation and the sum charged was reasonable.I intend to use them in future for all my work. They are due to return for a flat conversion.

New Combi Boiler
Customer Service
Had a combi boiler installed. I believe the work was completed to a very high standard. The workmen were polite and professional at all times. From the initial contact to the estimate to the date of installation everything was dealt with in a prompt professional manner. The company worked tidily and arrived each morning on time and work wascompleted on schedule. Would highly recommend them.

Broken toilet, fitted a new syphon. Good clean workmanship by the engineer who was very knowledgeable as he answered a number of questions I had about plumbing and heating. I would definitely use again.
