Gas and Central Heating Installations

We are Gas Safe Registered, qualified to offer a full range of gas appliances installations. We install all makes and are Vaillant Advance approved engineers.

Boiler Maintenance and Servicing

Unlike many Plumbing companies who simply use a gas analyzer, our service includes a physical check of the boiler and all safety components as well as cleaning inside.

Green Solutions

Our choice of planet friendly options include solar thermal hot water, rainwater harvesting systems, and bespoke wood burning central heating. Please contact us for more information and examples of our work.


Powerflushing cleans away the sludge and scale from inside your heating system, leaving it more efficient, reducing your heating bills and prolonging its life.

Landlords' Certification

Commercial Service

No commercial heating job is too large for Acorn Plumbing. We are qualified commercial gas engineers able to work on unlimited size industrial gas pipes. 

I found Acorn Plumbing to be professional & considerate, and would highly recommend these guys.
