Extract fan test and commissioning certificate

[Ajm]

We have come to completion on our extension which included relocating kitchen and a new en-suite bathroom

 

Building control have asked for:

 

Extract fan test and commissioning certificate

 

I've never heard of this being needed before. Anyone else come across this and how we go about getting this?

 

The kitchen has an off the shelf extractor (Airflow ICON 60) and the bathrooms are connected to a self-installed MHVR.

 

Thanks for any input

A load of nonsense that has been introduced.  I had these done on some flats.  It is mostly a paper exercise, but the firm were doing airtightness testing so this bumped up their money for the half day to £600 plus VAT.

 

Your MVHR will need proper commissioning but you can DIY this with an anemometer.

Thanks @Mr Punter - will BC accept DIY commission since there won't be a 'certificate' with someones name on it!
