If the boiler is connected by plug and socket it must be an unswitched

Surely it would also be ok to use a DP switched socket then? They're
pretty universal these days with SP only saving a few pennies at the
extreme budget end of the market...

Then I suppose there's the question of whether it'd be best to isolate
the boiler from the circuit earth when working on it...

Hwyl!
