Proper ventilation is vital for protecting your home’s health, comfort, and energy performance. Efficient Energy Homes Ltd offers certified Ventilation Flow Rate Testing to ensure your systems comply with Building Regulations Part F and PAS 2035.

 

What is ventilation flow rate testing?

We measure how well your mechanical extract systems remove moisture and stale air. This test is a legal requirement for all new builds, retrofits, and refurbishments-and ensures your home avoids problems like damp, mould, and poor indoor air quality.

 

Why ventilation testing is essential

Without effective ventilation:

  • Condensation, damp, and mould become serious risks
  • Air quality deteriorates, aggravating respiratory issues
  • Retrofit and building control sign-off can fail
  • Compliance with Part F and PAS 2035 is at risk

 

What we test

Our certified ventilation testers assess:

  • Intermittent fans (bathroom, kitchen)
  • Continuous Mechanical Extract Ventilation (MEV)
  • Mechanical Ventilation with Heat Recovery (MVHR)
  • Cooker hoods and specialist systems

 

We use calibrated equipment (e.g., Testo 417) to measure extract rates in litres per second (l/s) and provide a Part F Compliance Certificate.

 

Approved ventilation strategies we support

  • Natural Ventilation – Vents and openable windows
  • Intermittent Mechanical Ventilation – Fans for specific rooms
  • MEV Systems – Continuous extraction from wet zones
  • MVHR Systems – Balanced airflow with heat recovery

Each solution is tested for flow rates, performance, and compliance.

 

What you receive

  • On-site testing by certified technicians
  • Full digital report with performance results
  • Part F Compliance Certificate for Building Control
  • Advice on remedials and retesting (if needed)

 

Who needs ventilation testing?

  • New Build Developers
  • Retrofit Coordinators and PAS 2035 Projects
  • Housing Associations (ECO4 & SHDF compliance)
  • Builders, Installers, and Contractors
  • Homeowners upgrading ventilation systems
