Boiler Installation

We’ll make sure your new boiler is the boiler that your house needs. We always carry out a full site survey before installation. Knowing the demands of your house and listening to your specific requirements means we can get the right boiler for you.

Central Heating

We offer installations of all kinds of modern heating systems, providing a complete service from initial design ideas through to the finished job. Our experienced team will carry out a free survey and estimate and offer you advice on the best system for your property space. 

Power Flushing

Over time corrosion deposits from radiators and lime scale can collect in your heating system which will reduce fuel efficiency by up to 30%. Controls like pumps and motorized valves will get clogged up and fail, leading to costly breakdown repairs.
