Hi Andrew,

Thanks for your reply. I have decided to do the following:

Install a 13A socket behind the cooker hood which will be completely hidden.
The cooker hood will be plugged into this. The socket will be connected to a
visible FCU at worktop level. The FCU being on the kitchen ring circuit.

Does this sound as if it is in line with the regulations?

Thanks,

John

What are the options available to me to wire up a cooker hood, I can
think
of three ways but whether these are allowed/legal I do not know:

1. Wire it into the lighting circuit, but then there is no accessible
isolating switch.

Neither is there for most lights. It presumably has its own on off
switch?

...but you need a means of isolating appliances containing
motors.

You could use an FCU or an unfused double pole switch,
or a bathroom fan isolating switch (ignoring the 3rd
pole, but it will have an appropriate legend on it).
Some cooker hoods have quite high power fans nowadays,
so check the loading on your lighting circuit first.

2. Wire it into an FCU hidden behind the hood, but then do I also need
an
accessible isolating switch?

You need to be able to operate it for maintenance of the
cooker hood, i.e. before you open or take the hood down.
It doesn't need to be accessible for normal day-to-day use.
If it's far enough away (or out of sight) of the cooker hood
such that someone working on the hood could not be said to
be in direct control of it, it needs to be a type of switch
which can be locked off. Bathroom fan isolating switches
are often of this type, although they don't come with the
lock (it engages in two tiny holes either side of the
rocker, which you probably haven't noticed unless you looked
for them, holding it in the off position).

BTW, and plug and socket is also acceptable means of
isolation.

3. Wire it into the big red cooker switch.

Not a good idea, IMHO.

My cooker circuit has been turned into a switched radial
circuit by fitting 3 socket outlets in place of the
original hardwired cooker outlet. One has the oven plugged
in, another has the gas hob ignition plugged in and the
third was for some appliance previous occupant must have
had in the cupboard under the oven. If your oven plugs
into a 13A socket and you don't have electric hob, I see
nothing wrong in doing this.
