Whether you’re looking for an installation or user service manual or some simple guidance on how to use your appliance, we hope you’ll find what you’re looking in our boiler diagram section.

We never sell cheap copy parts.

We are the number one company when it comes to the delivery of genuine spares. We guarantee that each  product on our website is 100% genuine. They are tested and approved by Manufactures - we recommend you fit genuine boiler spares.

Because a copy part fits your boiler it doesn't mean they are manufactured to the same high standards that manufacturers expect from manufacturers. Counterfeit parts are very poor quality, unreliable and extremely dangerous.

Seems good value to opt for low-cost spares but consider the impact that this may have on the life expectancy of your boiler. Non-genuine parts are typically substandard and manufactured from poor quality materials.  spares are fully compliant with Gas Safe Regulations, protecting installers and consumers from the impact of installing non-genuine parts. All parts meet rigorous quality control standards and come with a 12-month warranty. 

We don't sell cheap copies! Should you find any cheaper parts online, then the chances are that they're non-genuine or reconditioned.
