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


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

It seems reasonable 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 inferior quality materials. HSP 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.
