Continuous extract systems where MVHR is not specified.
Extensions and lofts
Extract for new bathrooms and kitchens, background ventilation for new rooms.
Commissioning only
Testing and paperwork for systems installed by others.

Questions about ventilation for new builds, extensions and lofts in County Armagh
Which rules apply to ventilation in County Armagh?
In Northern Ireland, ventilation is covered by Technical Booklet K of the Building Regulations (Northern Ireland). Workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993.
Do loft conversions need ventilation?
Yes. New bedrooms need background ventilation, and a new en-suite or bathroom needs extract to outside.
When should MVHR be fitted in a new build?
MVHR ducts should go in at first fix, after the structure and before plasterboard. Planning it at design stage avoids clashes with joists and steels.
