The Benefits


NetRet - TrustMark Overview

What is Licence Plus

The Licence Plus Scheme provides a key route in supporting TrustMark Registered Businesses to engage in a transitional adoption of fabric-first, whole house retrofit. This additional aspect of the licence has been created to support the achievement of the UK’s Net Zero targets and aid homes in reducing their household energy bills.

The Licence Plus Scheme showcases the competency and quality workmanship of TrustMark Registered Businesses who can join the Licence Plus Scheme through participating TrustMark licensed Scheme Providers. The delivery structure is adaptable so that onsite audits of Licence Plus businesses can be carried out by Scheme Providers who opt to do so, or by TrustMark where required.
