Before, During, After - We’ve Got You

We support you before, during, and after purchase with practical, on-site know-how. From selecting the right kit to commissioning and aftercare, our advice comes from real jobs, not copy-and-paste manuals

Our Services

From design-stage SAP to as-built and EPC lodgement, we handle the full new-build compliance path. Expect clear guidance, fast turnaround, and Part L-ready documentation—so you can secure approvals and complete on time.

SAPs & EPC
Our UK & Ireland airtightness service uses blower-door pressurised and depressurised tests to verify leakage and pinpoint issues. We give practical, on-site guidance and fast certification, helping you meet Building Regulations and deliver better comfort, efficiency, and performance.

Airtightness Testing
Our engineers commission and balance your MVHR to the design: room-by-room airflow verification, quietness checks, controls setup, and filter guidance. We deliver clear handover and Part F documentation - ensuring healthy air, real comfort, and efficient operation from day one. As well as commissioning new MVHR, we service existing systems: inspections, deep cleans, filter replacements, rebalancing, and controls optimisation - restoring quiet, efficient, Part F–ready performance.

Commissioning & Servicing
From design to supply, installation, and commissioning, we deliver MVHR systems across NI and Ireland that are quiet, efficient, and compliant. Expect room-by-room balancing, Part F/TGD F documentation, and practical aftercare - plus servicing for existing units when needed.
