Primary Flow provides a complete gas central heating service, including planning the heating system for maximum performance and value, installing your boiler, pipes, and radiators in a neat and tidy manner, and continuing to service your boiler as needed. 

All central heating systems are custom-designed to fit your home, meet your needs, and reflect your preferences. I also understand that you may have a particular brand or manufacturer in mind, but I  recommend specific brands because of their dependability, performance, value, and serviceability, and I can offer extended warranties on Baxi, Worcester-Bosch, and Vaillant boilers. I also adhere to the highest industry safety standards, and as a gas engineer, I am fully Gas Safe registered.

I am also a fully qualified bathroom fitter, on hand to give your bathroom a refresh.  I am an approved installer for Stuart Turner pumps & Surestop stopcocks.  Get a quote for my bathroom installations today!
