New dwellings now require post-completion testing of ventilation equipment to comply with Part F of the Building Regulations.
All domestic ventilation systems should be tested, from basic extract fans to whole house mechanical supply and extract systems.
Ventilation testing comprises of the following:
- Checking the correct size and number of background ventilators
- Ensure internal doors have sufficient undercut to allow air transfer between rooms, i.e. 10mm over and above the final floor finish
- Ducted systems have been installed to reduce air resistance and leakage.
- Ensure there is sufficient access to routine maintenance
- Confirmation that each fan unit meets the minimum flow rate standards in the Domestic Ventilation compliance guide.
- A report is required for each installed address for Building Control approval.
- Ensuring ventilation ductwork within unvented spaces is suitably insulated.
