Cooker hood wiring (help!)

[Markray73]

Hi to everyone
I’m trying to fit a new cooker hood and need to wire it, unfortunately I have just moved to a new build and they have fitted a modern ceiling extractor that is supplied from a duel switch 3 core + earth ( one switch is on and second switch is boost) I need to wire in the new cooker hood which has a 3 pin plug fitted, my question is can I fit a single socket from the 3 core or should I fit a junction box only and cut off the plug and wire it in and if I can do either of these what do I do with the black switch wire? Thanks in advance

There is no reason not to fit a socket, except it may then be used for some thing else, if the hood is wired into for example lights, then plugging something else in could cause the overload to trip/fuse. I clearly don't know how it is wired, so there may be some thing I have missed. Up to you to do inspection and testing as when doing any electrical work.

Is there a way to spur from the extractor supply and fit a single socket ?

Why do you want to remove the ceiling extractor?

It sounds like the ceiling extractor has a switched live plus a permanent live (along with a neutral and earth). It may be the case that the perm live is there to power a humidistat sensor.

Why can't you use the supply to power both devices?

Hi Opps, I have a new cooker hood so I don’t need the fitted extractor, I didn’t want to keep both as it seems unnecessary. It’s starting to look like I may need to take a spur from a nearby socket, although I was trying not to do too much damage to the walls/ceiling as it’s a new build

This is what I have

Apropos minimal damage, I would be tempted to keep the extractor, but to run a supply back to the cooker hood. I assume that you don't have concrete ceilings.

Keep the existing fan, and supply the new hood from there.

Presumably you won't be bothering to fit an extraction duct for the new hood?

New build regs require kitchens and other rooms to have extractors to the outside.

If your planned cooker hood isn’t extracting to the outside then you really need to keep the ceiling fan too - which I suspect has a humidity option in it too

New build regs require kitchens and other rooms to have extractors to the outside.

Do you mean IF there is a fan it must vent to outside or

do you mean that there must be a fan (other rooms?) and it must vent to the outside?


What is this regulation?

Current regs on kitchen extractor fan

Hi Everyone, When I moved into my current house in 2017 I removed the extractor fan in the kitchen along with the elevated wall cupboards. I don’t need a fan as I don’t fry or boil anything on the stove, in fact I cook as little as possible. A friend recently told me that I am required...
