  • Full boiler service with all seals changed

    9.5Verified Review

    Tony was really helpful when explaining what the full gas boiler service would entail, reasons for changing the seals, and was flexible in arranging the engineer appointment at a convenient time. On the day he was punctual, polite and very tidy in the home. I will definitely use his services again, and would recommend to anyone looking for a quality and fair priced plumber.

  • Radiator change to a larger output

    10Verified Review

    Tony Jacobs was efficient in his work drained the system and replaced the new radiator checking all radiators are working efficiently. Carpet was protected with sheets before he started the job in hand. We also called on Tony Jacobs late in the evening on a separate occasion as the boiler was not working. He returned the next day after hours and replaced the part on the boiler. All very efficient and trust worthy. We have no problem in recommending Tony to other people as we have done in the past, very satisfied clients.

    10Verified Review

    I highly recommend Tony for his outstanding plumbing work! He efficiently installed a new boiler system, added radiators throughout the house, and expertly handled waste pipe removal. His attention to detail during bathroom and shower insulation was impressive. Tony's professionalism and skill made our experience seamless and worry-free. I would highly recommend Tony to friends and family.

Company info

Primary Flow can offer a full gas central heating service, from designing the heating system for optimum performance and value, installing the boiler, pipework and radiators in a neat and tidy manner and finally continued servicing of the system if required. 

All central heating systems are individually designed to suit your property, match your needs and include your choices. I also recognise that you may have your own preferred make or manufacturer although I would also recommend certain manufacturers because of their reliability, performance, value, and serviceability. 

I am honest and reliable, I believe in helping my customer with any questions they have, and to explain the whole process of the service that they require, whether it is for a new boiler replacement or a complete bathroom re-fit, my aim is to provide you with a service that you are happy with and to make the whole process as smooth as possible.
