Thanks. If I put a 3-pin plug on the boiler's cable and plug it into a
regular socket connected to the ring main, is that satisfactory,

The fact that the boiler is a bit of fixed equipment means that the
wiring you do for it also counts as fixed wiring, even if you do use a
plug and socket.

something more exotic required? There is already a standard socket
near the planned boiler location that I could use.

If you look at part pee he

See the additional notes section on page 10, section (h). (also have a
look at (n) while you are there).

That introduces an exemption if the socket you are connecting to is
already there. So in this case although the boiler is fixed equipment
the work is not notifiable if no new wiring is done to facilitate its
connection.
