OK, sockets mounted in kitchen base units is an accepted technique it
seems.
Which of the following is workable / the best:
1. Actually mounted on the wall behind with a cut-out in the back
panel (may have to mount socket on a plinth to make it span the
service void behind, looks a bit of a bodge).
2. Mount a surface box inside the cupboard (sticks out into cupboard,
back panel could be flimsy).
3. Mount a plasterboard-style hollow wall box into the back panel of
the base unit (back panel could be flimsy)

Those all work fine. Flimsiness can be countered reasonably well by
mounting it near the edge of the back, if you go that route.

This is the corect way.

No and no. My interpretation is that such cupboards do not count as
"building fabric" for the purposes of mounting fixed electrical accessories
or wiring on.

Although some may argue the other way as striplights are often mounted on
wall units and hard wired in - though at least the link-light version of
those is unpluggable.

I just used a very deep surface box to bring the socket forward.

My cooker socket is on the side panel of the carcass. The sparks who
fitted it seemed to think it was ok

Although I mount the sockets on the side wall of the cupboard right at the
back (unless otherwise instructed by a customer)

Who is that notice addressed to ?
I guess its the accessibility rules, to avoid the sockets being buried
behind pans etc.
I'd agree with mounting them near the top though, for that same
reason.

are not integrated types so I won't have a back panel in most places where

I have seen it where the first time someone trys to use the socket the back
of the cupboard falls off!

There really ought to be a clear guidance of the use of sockets in cupboards
by the IET.

Its quite common to fix the sockets in the next cabinet in that case,
and have the cable and plug going through a hole. I'll try to avoid
stuff (plumbing / electrics) behind e.g. washing machines, since they
need to be pushed back quiet far. I've seen many washing machines
sticking out quite a bit for presumably this reason.

Wow, that's fugly.

Presumably at least part of the reason for side mounting is because
their kitchens have very flimsy backs rather than 18mm (and it's
quicker and easier than messing about with non-surface mount stuff on
plinths etc).

I do mine the metal backbox on plinth on wall way, based on the 'must
be attached to building fabric' rule oft-quoted on here.

Someone tried to get such guidance a while back but the IET declined to
give it. See
http://www.kitchensfitted.co.uk/KitchenForum/building-regs-part-p-t253-15.html

I have been wasting the odd few minutes looking for further guidance on
this issue about kitchen fixtures since it was raised a few days ago.
The best I've found is (as in that link) that it is "good practice" to
fix to the fabric of the building but that fixing to kitchen worktops,
carcases etc is not against the regs. Which I think is what you've
said.

I would have been inclinded to use the surface mount boxes on a plinth
(white plastic ones), but I guess why not use a metal back box, since
it will not be visible.

> Simon.- Hide quoted text -

Surface mount boxes are bigger so the socket plates do not overhang.
So, if used recessed, show the raggedy edges on the hole.

So stopping a metal backbox a mm or so short of the face of the back
is neater for a flush socketplate.

That was my rationale anyway.

There's a recommendation (I think from NICEIC) not to do it, but it's
not against the wiring regs. I guess it depends if you think your
wiring will last longer than your kitchen. In practice, most kitchens
are rewired when the kitchen units are changed, so the units can be
considered as permanent as the wiring.

For IKEA cupboards with backs flush to the wall, you just fit a standard
flush wall socket and cutout the rear panel. I usually do it as a close
fit to the back box, and refit the socket flush inside the cupboard, so
the rear cutout is invisible behind the socket plate.

I have one behind every floor standing cupboard, in case it't ever
replaced by some appliance. In most cases, I feed the appliance plug into
the adjacent cupboard's socket, so it can be accessed without having to
move the appliance.

For sockets under the sink, they are in surface mount waterproof
enclosures so that a spill or leak into the cupboard is not
electrically unsafe.

If I need to install a socket outlet inside a floor unit, I
mount it on the wall and use a floor unit without a back
panel.

Indeed - although its usually harder to get the plumbing slim enough
rather than the electrics.

One area where the "mount on the fabric of the building" argument fails
is when you have either an island or a long "return" of worktop. For
example we have a return section that has a double corner cupboard, then
a set of drawers, and then a built in under worktop fridge. Hence the
socket has to be in the adjacent drawer unit at the back since there is
now way to easily get back to a real wall.

Which is odd as you would think that it is part or their job:-)

The IEE really needs to think about the problems that an electrician is
faced with when wiring a kitchen. The customer tells you what they want but
have no practical idea on how to do it (the same applies to architects). It
is all very well saying "feed a single socket from a FCU for the washing
machine" and actually finding out that the socket stops the washer being
pushed back flush with the worktop. Add to that the number of people who are
paying lots of money for splashbacks and do not want FCUs on the wall above
the worktop. There cannot be a "standard" as customers want different things
and as long as the work is safe I do not see why a socket cannot be in a
kitchen cupboard (but not under the washing machine plumbing connectors)
