Decarbonisation Training, Qualifications, PAS and TrustMark

GN Group Ltd facilitated the creation of Wales’s first TrustMark Scheme Provider, NetRet Group Ltd (NetRet).

Collaborating with 6 leading Housing Associations, and considering the observations put forth by Welsh Government and TrustMark, GN Group brought together the necessary resources and skills to establish a central decarbonisation certification and training company (NetRet). 

NetRet was formed to assist contractors, surveyors, the social housing sector, the wider public and private sectors, as well as helping to upskill local communities and build a strong foundational economy i.e. all deliverers and stakeholders connected with decarbonisation. GN Group continue to work with and support NetRet as a key partner, working with LA’s, HA’s and contractors to develop the strategic elements of their decarbonisation journey.
