[About fixed appliances being plugged in]

I was asked to PIR a large Edwardian villa that had been converted
into eight flats. In each case the flat's combi boiler had been
located in a bathroom cupboard.

This should not have been a problem as all the controls had been
positioned elsewhere. Unfortunately the installer had used a plug and
socket to connect the boiler rather than a FCU, with the result that
the tenants had used the "handy" socket to plug in other appliances.

I really can't see why this is "dangerous" !

No, sorry, you're missing the point.

I'm not concerned about the socket being overloaded. The MCB would
protect the cable assuming it had been specified correctly at the
design stage. Like fuses, MCBs protect the cable and not the
appliance.

What I am concerned about is there being (in the example I gave) a
socket installed in a bathroom. This is definitely a bad idea - as
well as being prohibited by the regs. In this case there was not even
a RCD as a backup safety device.

One flat had a hairdryer plugged into the socket and lying on the
glass shelf over the basin. Sooner or later somebody will knock it
into the basin, and then reach into the water to pull it out...

If the boiler was wired into a FCU then the socket would not have been
available to be abused in the first place.

On a PIR I would (and did) flag up such an installation as being
unsafe and requiring immediate attention.
