The only thing I can see in part F is that for intermittent fan controls in a room without natural light a 15 minute overrun is required and the fan could be controlled with the main light but not must be controlled by the main light.
I could be looking in the wrong place but I can’t see a rule saying must come on with the light.

I just had a looky look too - I agree. And it says the fan should be able to be manually operated. So I think the planners have made an interpretation of the regs that isn't what was actually written :)

Like I say I have never been pulled by the building inspector.
As long as he turns the switch on (2 gang separate switch for fan) and turns it off and the fan runs off the timer he’s happy for window less rooms be it utilities and bathroom/toilets.
I don’t think he timed them tho :)

The planning portal ref @Midwest has provided above implies the fan should come on with the light and says it should run 15mins after the light is turned off :) .

And people wonder why the Grenfell disaster happened.

The Planning Regs are the responsibility of the DCLG - they write AWFUL documents and need to be held accoutantable ......

I have been giving a pursue of the approved document F, as opposed to the Planning Portal statement, always ready to correct myself.

Firstly it does state that extraction to the outside is required for kitchens, bathrooms, utility rooms & sanity accommodation (5.5), simples.

As to the control of said ventilation, it slightly less clear (for me). For a room without opening window, an intermittent extraction should have a fifteen minutes overrun. In rooms with no natural light, the fans should be controlled by the operation of the main room light switch (Table 5.2A) (not a direct quote, but all I can be arsed to type).

Why the dumb Adam? I did say it was possibly correct and that I had never used one, quite what's dumb about that reply is a dumb response on your part, but hey ho we are all allowed to respond how we feel however dumb it may be to the dumb person responding with a dumb reply.

I believe so
I’d have thought if it was a must then it would’ve be worded as such.
To me it’s just giving an opinion if you wanted to do it this way.

As I said before the DCLG are responsible for these badly worded documents ....

So back to the OP .............my post #2 was correct.

If the sparky won't change it, (you may have to pay) then get somebody else in afterwards ........................ BUT depending on how its been wired, the changes may be messy.
 
In simple words "if you want it you can have it"

I would definatly say its fine i have dobe it a few times as it is ob the spec for the new install and it have never been pulled by any one. Tell your spark you want it if not get another electrician to do it.

Oh no! not another one, this post should make it 3 in a row from Adam:tongue::handfist:
 
Part F says that in a room without an opening window, an intermittent fan should have a 15 minute overrun. It mentions that in rooms with no natural light, if MAY be appropriate for the fan to be controlled by the operation of the main light in the room.

To the OP: you can have your fan on a separate switch, but if the room doesn't have an opening window, your fan should be a timer model that is set to run on for 15 minutes after you have turned the fan off.

Wiring a new 2 gang switch from a single two way switch.
"It works" and "it's safe" are not necessarily the same thing. With DIY work, they are often far from the same thing.
