Choosing an NIA member helps to ensure that all products, systems, and installations are delivered to a high standard, in line with industry best practices.
It’s a condition of joining us that each member adheres to best practice guidelines and commits to complying with all relevant industry standards. These standards, on retrofit projects, include PAS2030 and PAS2035 (see below), which are referenced in the government-endorsed TrustMark certification scheme.
Installer members also commit to undertaking regular training to keep their skills and knowledge up to date. Accordingly, work carried out by NIA members is generally eligible to be supported by OFGEM / TrustMark approved guarantees, as provided by our associate members.
