Retrofit & PAS 2035

PAS 2035 is the over-arching document in the retrofit standards framework, with which users of the TrustMark Government endorsed quality scheme are required to comply when carrying out domestic
retrofit work.

To be eligible for public funding, projects must be delivered in strict compliance with PAS 2035. The specification is fully supported by BEIS. Compliance is a mandatory requirement of schemes wanting to operate under the TrustMark – the new quality mark for the Retrofit Sector.
