strung together this:

If position 10 is unavailable then provided the central heating on No7 is
only a pump and controls (i.e. NOT immersion heater as well) you could wire
it through a FCU fused at 3A and and supply the FCU from one of the power
rings.

Rather than any one, use the upstairs ring as this isn't covered by an
RCBO. That way the heating will still work if there is an earth fault
on the downstairs ring.
