Yes all our products come with a guarantee.
Guarantees or warranties vary, by product and manufacturer.
All our products are guaranteed for a minimum of 1 year (radiators 10 years, copper tube 25 years) but many offer longer warranties from the manufacturer, which you may need to register for.
On each product, under the specification tab, you will find more information on the guarantee or Warranty.
Follow links through to various manufacturers sites, as each manufacturer will have its own terms and conditions for qualifying for longer warranties.
You do not want to miss out by getting the wrong installer for some boilers etc.
As Boilers and radiators are installed by third parties, they do have to install in compliance with regulations and manufacturer standards to get the full benefit of the warranty.
As long as these ar fulfilled, you will get the maximum life and support from your new purchase.
