Part F – Ventilation Testing

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.

If you appoint Gladwood to carry out your Part F and Air Pressure testing during the same site visit, you will save over £200.00!
