Part F building control notification

[Aaron b]

Hello, I understand that from the 15th of June testing and commissioning of vents and fans is now compulsory and that also since last year any works regarding fans needs to be notified to building control under part F.
I assume that this can be done as a NAPIT contractor registered with EAS. I've had a look through napits Ventilation Certificate, the details in appendix C of part F and the Domestic Ventilation Compliance Guide and the commissioning seems overly onerous and requires specialist equipment. Is anyone here doing part F notifications, commissioning or the full ventilation survey that appears to be required? I'm either thinking of blaming the plumber or offering it as a separate service...

I was vaguely aware there were now more onerous requirements regarding ventilation & fans, but haven't looked into it as yet. NICIEC has this 2-page summary:

I don't do that much in the way of ventilation, so personally I'm inclined to check exactly what needs notifying, and make sure I decline any such work!

Testing and the fan airflow is a specialist job.
In a new build it would normally be done when the air pressure / airtightness test is done and arranged by the main contractor / developer.

Is this just for new builds >?
Or any job where a new fan is installed ?

No; see the last paragraph of page 1 of the link in post #2.

No, that only measures air speed. Ventilation is about the volume of air being moved,

Surely if it can hold a piece of toilet roll in place it's doing its job correctly

I would say 8 out of 10 fans I come across will hold a single sheet of andrex up , however 7 of those 8 fans are just sucking air into the the loft space

Classic example of the gulf between what the powers that be are concentrating on, and what they should be concentrating on.

@Dustydazzler I'd say I've only fitted around 20 bathroom fans in my time, all for friends and family, about 5 new and the rest replacements and I've only came across it once. Incredibly lazy approach probably speaks volumes for the rest of their work.

 

[Dustydazzler]

In 25+ years of doing Domestics I have probably replaced around 500 fans and I would say a huge chunk were never vented properly, either straight into the loft (no ducting) or a short bit of plastic duct just buried under some insulation. I know its not the end of the world just shoddy

I'v ducted the shower ceiling fan into the top of the cold water tank, seems a waste to vent it to air through the roof.

It’s not just water vapour being sucked away. There will be smells, gasses, ahem

You’ll be using that water to clean your teeth…..

Just remember not to swallow.

I think manufacturers should certify and test their fans. They should give a certifcate with the fan you buy to show it complies. It seems once again we are being asked to do manufacturers work. /sigh!

 

[Mike Johnson]

Would that require the manufacturer to test with different ducting systems and length?

It's the installation that is being tested, not the fan.

 

[Vortigern]

It's the installation

...of what?
