  • Our boilers have manufacturer warranties of up to 10 years for your peace of mind.
  • All Engineers are respectful to your property – they use dust sheets, feet covers and vacuum cleaners to ensure we leave your home the way we found it, only warmer!!

Quality Check

Our work is only complete when we know you are 100% satisfied with your installation.

As part of our aftercare service we will ensure your boiler is registered with Gas Safe and with the manufacturer to ensure you receive the full warranty with your product.

Power FlushPower Flushing

We provide a full range of power flushing services to ensure your system is operating as efficiently as possible.

Sludge in your heating system can cause blockages and corrosion which can lead to both inefficiency and breakdown. In extreme cases, it can be so damaging that a complete boiler replacement is needed. It can also mean that the radiators on the current system will not heat up correctly, you will notice cold spots and the radiator would be cold at the bottom.

The process includes a chemical that will remove sludge and rust, a descaler to remove limescale and a corrosion inhibitor to help prevent future rust from forming. Our engineer will collect and dispose of any contaminated water, debris or particles that they remove from the system. If a filter isn’t fitted, we will fit one to help protect the current boiler.

Boiler Service, Maintenance & Repair

It is very important and indeed a condition precedent to maintaining a manufacturer's warranty, to have your appliance serviced annually. It can help identify problems before they get out of control and it gives you an idea on how efficient your appliance is.  Poorly maintained or faulty boilers can present a serious health risk to you and your family, because they can cause fatal carbon monoxide poisoning.
