The challenge
The challenge.
The estate's ventilation hadn't been cleaned in over five years, restricting airflow and putting the trust at risk of failing its TR19® compliance audit — and all work had to happen around live clinical areas with zero disruption.
Our approach
Our approach.
We surveyed every system, agreed an out-of-hours programme, and cleaned to TR19® standard with full before/after photographic reporting.
- Phased, out-of-hours working around clinical areas
- Access panels installed where needed
- Post-clean airflow verification
The results
The results.
Airflow was restored across all three sites, the trust passed its compliance audit, and every job was backed by a complete photographic record.
