Extract Ventilation Testing Liverpool
Professional extract ventilation testing for new-build homes, residential conversions and housing developments throughout Liverpool, Merseyside and surrounding areas. We measure installed airflow rates and provide the documentation required to support Building Regulations compliance.
What Is Extract Ventilation Testing?
Extract ventilation testing measures the airflow performance of mechanical ventilation systems installed within a property. This commonly includes extract fans serving kitchens, bathrooms, shower rooms, utility rooms and other wet areas.
The test confirms whether the installed system is delivering suitable airflow rates and operating as intended. The results can be provided to the relevant Building Control body as part of the evidence required before project completion.
We can coordinate the testing at the appropriate stage of your development and provide clear feedback where the installed ventilation system does not initially achieve the expected performance.
Our Testing Service
Ventilation Systems We Can Test
Our service can cover the most common forms of mechanical ventilation installed within domestic properties and residential developments.
01
Kitchen Extract Systems
Measurement of mechanical extract airflow serving kitchens, including applicable continuous and intermittent systems.
02
Bathroom Extract Fans
Airflow testing for extract fans installed within bathrooms, shower rooms, WC areas and other wet rooms.
03
Utility Room Ventilation
Performance testing of mechanical extract ventilation serving utility rooms and other moisture-producing spaces.
04
Continuous Extract Systems
Testing of decentralised or centralised systems operating continuously at background and boost airflow rates.
05
MVHR Airflow Rates
Measurement and balancing support for mechanical ventilation with heat recovery systems where applicable to the project.
06
Retesting and Support
Where the system does not achieve the expected performance, retesting can be arranged following adjustment or remedial works.
Preparing for Your Ventilation Test

Frequently Asked Questions
Extract Ventilation Testing FAQs
At what stage should extract ventilation testing be completed?
Testing should normally be completed once the ventilation installation is fully finished, powered and operational. All extract terminals, ductwork, controls and external grilles should be installed before the engineer attends.
What happens if the ventilation system does not achieve the required airflow?
Low airflow can be caused by restricted ductwork, incorrect fan settings, unsuitable terminals, excessive duct lengths or other installation issues. The system can usually be adjusted or corrected before a retest is arranged.
Is ventilation testing the same as air tightness testing?
No. Ventilation testing measures the performance of the installed mechanical ventilation system. Air tightness testing measures uncontrolled air leakage through the building envelope.
Can several properties be tested during the same visit?
Yes. Several plots or apartments can often be tested during the same attendance, provided each property is complete, accessible, powered and ready for testing.
What information is needed for a quotation?
We would normally require the site address, number and type of properties, ventilation system details, expected testing date and any relevant plans or specification information.
Can you help with other Building Regulations testing services?
Yes. One Stop Consult can coordinate a range of related services including air tightness testing, sound insulation testing, SAP calculations, water efficiency calculations and Energy Performance Certificates.
