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

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.

Quite. I'd rather have a boiler fed via a plug and socket - single or DP
switched - than an FCU, since you can unplug it. A definite air gap is
more confidence building than any switch.
