Elmhurst hosts TrustMark team for Airtightness and Background Ventilation Training
Elmhurst Energy recently welcomed members of the TrustMark compliance team to its Combined Level 1 Airtightness and Background Ventilation Testing course, reinforcing the importance of technical competence in auditing retrofit standards.
Who are TrustMark?
As the UK’s government-endorsed quality scheme for work carried out in and around existing homes, TrustMark plays a pivotal role in auditing Retrofit Coordinators and Installers under PAS 2035.
Why does Airtightness and Background Ventilation matter?
Recent updates to standards and guidance, including Elmhurst’s own clarification on airtightness and BVT for retrofit projects, have highlighted the need for accurate, consistent testing to support compliance with PAS 2035 and Approved Documents F and L. While some measures, like air pressure testing in RdSAP 10, remain optional, their impact on retrofit outcomes is significant.
Poor ventilation has been linked to damp and mould issues, which are now under greater scrutiny following the confirmed introduction of Awaab’s Law on the 27th October 2025. This legislation mandates faster action on damp and mould in social housing and is expected to drive higher ventilation standards across the sector.
Elmhurst’s Head of Training, Josh Wakeling, commented:
“It’s fantastic to see TrustMark leading by example. Their presence on this course shows a real commitment to understanding the technical detail behind the standards they audit and that’s a win for the whole industry. Airtightness and ventilation are no longer niche concerns, they are central to delivering safe and compliant retrofit projects and we look forward to working with others in the industry to upskill in this area.”
Paul Phillips, TrustMark’s Technical Director said:
“Airtightness and ventilation are central to delivering safe, efficient, and compliant retrofit projects. We are happy to be working with our scheme partners and are working with our team to improve technical skills.”
