Background Ventilation Testing
(Cyfieithiad i ddod yn fuan)
Thorough, reliable testing every time
Egni Energy Solutions provides professional Background Ventilation Testing (BVT) for PAS 2035 retrofit projects across North Wales.
As retrofit measures improve airtightness and thermal performance, ensuring adequate background ventilation becomes a key compliance requirement. Our role is to provide clear, independent verification that the dwelling can adequately breathe following improvement works.
This service is separate from extractor fan flow rate testing. It focuses specifically on whole-dwelling background ventilation provision within retrofit environments.
We work alongside retrofit installers to help projects progress smoothly to sign-off.
How We Support Your PAS 2035 Projects
We understand the pressures of retrofit delivery — funding timelines, scheme requirements, and audit scrutiny.
Our Background Ventilation Testing service provides:
- Independent verification for PAS 2035 documentation
- Clear reporting suitable for Retrofit Coordinators and scheme audits
- Prompt scheduling to avoid delays
- Straightforward communication if improvements are required
If rooms have previously experienced mould or condensation issues, our assessment helps demonstrate that ventilation has been properly considered following retrofit works.
Our approach is practical and proportionate — focused on keeping your project compliant and moving forward.
Early Booking Keeps Projects on Track
Engaging us early helps:
- Avoid last-minute compliance issues
- Prevent delays at project sign-off
- Provide reassurance to Retrofit Coordinators
- Protect installers from avoidable call-backs
We regularly coordinate this service alongside airtightness testing where required, offering a streamlined compliance package for retrofit schemes.
