I have recently purchased a flat which has the plumbing for the
washing machine and a RCD power point in the bathroom,(an RCD plug
Socket) its in a old airing cupboard with the door removed (Washing to
big to fit in with door). Is this legal. Should the washing be hard
wired to the RCD output ?
Any advice appreciated
Take a look at zoning.
You are allowed RCDed sockets at a certain large distance away from the
shower/bath (2.4m I think), provided the room isn't a dedicated bathroom. I
suspect you could get away with saying it is a utility room and thus
I think you could install in Zone 3 (0.6m to 2.4m away) if it is hard wired
into a FCU protected by a 30mA RCD. I'm not sure, though, and I don't have
the regs with me to check.
The RCD out let would come under Zone 2. The valliant boiler which is
mounted in the same cupboard specifies connection to the mains supply
shall be made via a fused 3 pin plug to a unswitched shuttered socket,
both complying with BS1363 (Alternatively, connection may be made via
a 3amp fused double isolator having a contact seperation of at least
3mm in all poles amd supplying the boiler and controls only). Why
cannot the same apply to the washing machine ?

That's acceptable from the boiler manufacturer's point of view, but the
boiler manufacturer can't rewrite the IEE Wiring Regs that say you can't
have sockets in a bathroom (and I think Christian's suggestion that putting
a washing machine in it makes it a utility room a little bit naughty :-)) so
in a bathroom you must use

^ one of them.

The same does apply to the washing machine.
So if I Put in a inline RCD followed by two fused double pole
isolators, one for the Boiler 93A) and one for the washing machine
(13A) that would be acceptable ?
Is there some way that the washing machine could be disconnected
quickly in a emergency, say some sort of screw in plug? That would be
better but if there isn't I could use the switched Isolators.
1m from the bath is Zone 3. However, I don't think that (I'm not quite sure)
the outlets may be positioned here, even if the appliance may be. The
outlets can be made outside the zones by 3 methods:
1. Move > 2.4m from bath/shower.
2. Move outside the room.
3. Box them in such that a tool is needed for access.
I found the following document which makes it all clear
Basically Washing machines should be fitted in Zone 3 with a 30mA RCD
to a fused outlet or switch out let plate. If they have to be in zone
2 they should be IPX4 rated but there has to be good justification for
placing them here.
I still haven't got the regs with me, so I'm not speaking with any
confidence. This is all from my rather hazy memory.
However, my understanding is that the boiler probably wouldn't be compliant
either. I would have though it should be in Zone 3 or outside the zones. I
seem to recall that the socket or FCU (which must be 30mA RCDed somewhere)
should be outside the zones. The boiler must also be room sealed. Open flue
is not allowed in a bathroom.
The zones are basically:
Zone 0 = under water
Zone 1 = wet
Zone 2 = dry, but within reach of shower/bath
Zone 3 = dry, but you might still be wet and undressed
Outside = dry, probably towelled yourself off and got dressed by now
You can make any area outside the zones if you box it in and require tools
(i.e. a key) to gain entry. The regs consider it unlikely that you will
remove the inspection panel in the nod. So, the FCUs could be in the airing
cupboard with a small MDF cabinet surrounding them with a removable panel
that requires a key to remove (or just screwed down so you need a
