MK fan isolators are lockable I know that for sure.
True, got one at home.
Seem pretty crappy though, Two tiny plastic pins to lock the switch off.

So does mean that the BGB, is in a roundabout way, law?
you are saying that no isolation is required close to the fan and then that no 3 pole device is required for isolation.
Just because you interpret the regs your way doesn't make it correct does it?
I really can't believe some of the comments here concerning providing BS fuses protection to both permanent live and switched live, I would consider that wiring knowledge as 1st year stuff...
"If you follow the wiring logic above would that not do away with the need for the triple pole? Both feeds for the fan are through the fuse which can be removed and the fuse carrier locked open for safe isolation so regardless of location safe isolation is satisfied? "
I would think so...
Sorry I didn't read all your post, before posting again...
Find me some regulations then that prove me incorrect. If you can, I'll happy eat humble pie, until then why not keep your arrogant remarks to yourself.
And guess what, the beauty of non-statutory regulations is that they ARE often open to interpretation.
Arrogant? do you know what it means?
Aren't you the one that decided to give all of us the bennifit of your regs advice? the regs are minimum and they are are for interpretation but not for making installations less safe.
You are attempting to give advice in a special area which could provide or give some readers incorrect advice. If the readers have to rely on this forum for knowledge you should be promoting safety and not scraping the regs for quick get outs.
It is common practice to install an FCU to comply with the manufactures requirements for maximum fuse requirements, it does mention manufactures requirements several times in the regs doesn't it?
and anyone not installing a 3 pole switch doesn't understand the RCD requirements.
As I mentioned many here don't understand how to wire a BS 1362 fuse into a system let alone follow your " A source of much controversy" there's no controversy and safety is paramount not the regs.
Switching an mcb off is not isolating, unless it's a double pole mcb. Therefore the fan or item of equipment being "ISOLATED" by an mcb, technically is not.

since when does a domestic bathroom fan require D.P. isolation ?
This one is a Newlec, and from my google search for the phrase "triple pole isolator with lock" it seems MK do one as well. They come with a little key to operate the locking device, which I imagine disappears without trace after 10 minutes of the installer leaving the buildingStroppy, what make is this? Never seen one before and not in my wholesaler, I do use on line and may have never picked this up being a small catch/ screw on the bottom."
i recon that the hse would require safe isolation[ie; not working in the dark, with half the lights in the house off, and a torch in your mouth
my solution is going to be to fit a DP secret key switch with fuse on a grid switch with the faceplate engraved "Bathroom Ventilation"
Head torch.So what do you use for illumination when you're working on a lighting circuit?
Freaking heck i'm gonna get my hard hat on ! Thought it was a forum not a boxing ring lol
Just had an issue about ventilation fans in bathrooms and looks like my solution is going to be to fit a DP secret key switch with fuse on a grid switch with the faceplate engraved "Bathroom Ventilation" it's going to be located in the adjacent store cupboard and wired onto the lighting circuit so tenants are disuaded from turning the CB off.
The fan has humidistat and pull cord overide so no issues with over run.
