Which? Local Review

Extremely helpful with respect to central heating servicing, gas cooker installation and electrical advice. We will definitely call up Justin and Peter , his electrician, again. Prompt, courteous and reliable service in a very busy area.

Prompt professional and tidy

Our 22 year old condenser boiler failed beyond economical repair. I obtained several quotes (including the big nationals) for replacement and installation of a Worcester Bosch 24I system boiler (Which best buy) and Justin Fishwick quote was fair and reasonable. Chose J. Fishwick Heating because they are local and could start within the next few days. Installation was completed on time and on budget, I requested a system valve to be replaced also which was done. They were professional and tidy, removed and disposed old boiler and associated hardware. I have two neighbours who are interested to use J. Fishwick to replace their aging boilers. We intend to use J.Fishwick for routine annual boiler service.

Excellent Central Heating Installation

After having only electricity for many years I decided to have gas central heating installed. After calling 3 plumbers for comparative quotes I was pleased to meet Justin from J Fishwick Plumbing & Heating Engineers. He gave me the best advice on the most cost effective & efficient system for my property. The price of the whole system was cheaper than that quoted from his competitors with a longer guarantee and professional back up. Very clean & punctual I would highly recommend


Great Service

Justin and his team spent just 3 days, removing my old fireplace boiler, hot, cold, heating water tanks, installing a new condensing boiler, new gas feed, water softener, heating filter. I highly recommend J. Fishwick, and would use them again.
