I needed a new boiler and central heating system. After getting a couple of quotes, I chose Lee from Pierson Heating. He took the time to explain the different options and helped me choose what would work best for my home. The installation of the new combi boiler, radiators, and pipework was done exactly as I wanted. I’ve already recommended him to friends and family.

Pierson heating installed our combi boiler, after many years of service and repair work for us it was time for our new boiler replacement. Great job, would highly recommend.
Pierson Heating were recommended to us by our son who had a boiler installed by them earlier in the year. The job took 3 days, which involved power flushing system, renewing 4 radiators, thermostat valves, changing some pipework, fitting new pump and wall thermostat, also installing a new boiler. Lee and Ewan worked very hard, they were friendly, competent and tidy, we have no hesitation in recommending Pierson Heating.

Boiler replacement FAQs
How do I know if I need a repair or a full replacement?
This depends on the age and condition of your boiler and how often it has needed repairs. An engineer can assess your system and advise whether a repair or replacement makes more sense.
How long does a boiler last?
It varies by make, model, usage and how well it has been maintained, but boilers are generally considered for replacement somewhere in the 10 to 15 year range.
Do I get to choose the boiler brand?
We are an accredited installer for both Worcester Bosch and Vaillant, so those are the brands we are accredited to install. Get in touch to discuss what would suit your property.
Is a Gas Safe certificate included?
All gas work is carried out by Gas Safe registered engineers, in line with the legal requirement for gas work in the UK.
