Extract fan testing ensures that the installed fans in rooms such as Bathrooms, Utility and Kitchens are performing the required air-flow rates to meet compliance with Part F of Building Regulations and to guarantee a healthy and comfortable internal environment for the dwelling’s occupants.
The Domestic Ventilation Compliance Guide (DVCG) published in 2010 gives the approved procedures for measuring air-flows and reporting the results for Systems 1 to 4 described in Approved Document F 2010. Our BPEC qualified engineers use a calibrated hooded anemometer to measure and record the air-flow rates from the extractor fans.
Following the fan testing procedure we will provide you with an Inspection Checklist and Part F Air-flow Measurement Test Sheet for each dwelling as required by Building Control to demonstrate compliance with the required air-flow rates in Approved Document Part F.
The main task of ventilation is to remove polluted indoor air from a building and replace it with fresh outdoor air. Polluted air includes moisture from washing and cooking, Carbon Monoxide from combustion appliances and smoking, Volatile Organic Compounds from aerosols, furniture and carpets and Allergens from house dust mites. On average each household member produces 5 litres of moisture per day.
Regulation 42 of the Building Regulations 2010 requires builders and developers to provide evidence of the testing of all fans to the Building Control Body (BCB) within 5 days of the test being carried out.
