BESA Double Guarantee

Peace of mind guarantee for work done in your client's home.

When a client employs a BESA contractor to install, replace, upgrade, extend or repair the heating or air conditioning system in their home, they will automatically be covered by the BESA's Double Guarantee at no additional cost.

The BESA Double Guarantee applies to domestic heating, plumbing, air conditioning and solar PV installations only with an installed value over £500 up to £50,000. It will be invalidated should any third party carry out work on the installation carried out by the BESA member.

Clients can even pass the remainder of the guarantee on if they sell their home.

We have created a BESA Double Guarantee flyer you can give to your clients, showcasing all the great benefits of employing a BESA member and what is included in their warranty.
