Stroma Built Environment’s experienced Part F ventilation assessors can guide you through your legal responsibilities, identify potential issues early on, and ensure your ventilation systems are up to standard with minimal disruption to your projects.
Part F Ventilation Testing
For all new build developments in the UK, it is now a legal requirement to assess the performance of ventilation systems. Proper ventilation is crucial for preventing condensation, poor indoor air quality, and mould growth – issues that may lead to health problems and structural damage if not addressed.
At Stroma, we provide professional Part F ventilation testing and consultancy fully aligned with Building Regulations Part F to inform the best strategies for ventilation design, installation, and maintenance in commercial and residential properties.
Using approved methods, including pressure testing, smoke testing, and thermographic surveys, we deliver rapid, highly accurate results and reports to help you achieve your ventilation targets and ensure compliance.
Building Regulations Part F Ventilation Requirements
Building Regulations Part F provides essential guidance on ventilation standards for both domestic and non-domestic new build dwellings. Ventilation involves the removal of indoor air and its replacement with fresh outdoor air to dilute airborne pollutants, control excess humidity, ensure adequate air for breathing, and supply air for fuel-burning appliances.
Part F ventilation requirements aim to create safe, comfortable environments for occupants by covering the use and performance of both natural and mechanical ventilation systems under the following conditions:
- Minimum Ventilation Levels: Rooms must have a minimum level of purge ventilation or mechanical extract ventilation.
- Ventilation for Less Airtight Rooms: Less airtight rooms should achieve minimum ventilation through natural means, such as background ventilators and trickle vents.
- Ventilation for Airtight Rooms: Airtight rooms must be equipped with mechanical ventilation systems.
- Ventilation for Kitchens & Bathrooms: Kitchens and bathrooms must provide adequate extract ventilation.
- Ventilation for Windows: When replacing windows, any existing trickle vents must be replaced. For windows without trickle vents, it must be demonstrated that the replacement windows will not worsen ventilation due to changes in airtightness.

Frequently Asked Questions
What is Part F of the Building Regulations?
Part F Building Regulations outlines the ventilation requirements necessary to ensure good indoor air quality in both domestic and non-domestic new build dwellings. It sets standards for natural and mechanical systems, covering aspects such as ventilation rates, design, installation, and maintenance.
Part F ventilation testing is essential for verifying that ventilation systems comply with these standards, preventing issues like mould growth, condensation, and poor air quality. By adhering to Building Regulations Part F ventilation requirements, buildings can provide a healthy and comfortable environment for occupants.
What information do you need to complete Part F testing?
To complete Part F testing, we require the following:
- Floor plans of the property
- Details of the ventilation system (including design & plans)
- Standard Assessment Procedure (SAP) calculations
- Ventilation systems must be installed & fully operational
How do I avoid failing Part F ventilation testing?
There are several steps you can take to help prevent failing Part F ventilation testing, including:
- Avoid sharp bends or long runs in your ductwork
- Don’t kink or squash flexible ducts to fit tight spaces
- Ensure ducts aren’t excessively long to maintain efficiency
- Properly seal joints & insulate ducts to prevent air leaks
- Inspect & maintain ducts to keep them clear & in good condition
