I see that many suppliers now offer both SP and DP versions of switched

What governs which version one should use?
You can't use a switched one of any variety for supplying a boiler.
I think you mean "may not" rather than "cannot", since my boiler's been
plugged into a switched socket for 21 years to my knowledge, and it works
just fine.
That means you can just unplug your boiler from the socket for electrical
isolation and you do not have to give a give a **** about the socket having
single or double pole switching.
FWIW I don't think I ever use a socket switch to turn something off for
any purpose, never mind maintenance where safety might be involved.
I'd wager that in this house, every switched socket is either switched
on with a plug inserted, or switched off with no plug inserted.
Perhaps that's just me. But I suspect not.
