Might be a lot cheaper and easier to use a UPS rather than a genny.
That way you've got battery backed up CH 24x7 and never need to worry
about switching over.

Power the UPS from a 13A socket - and if the UPS battery gets a bit
short then unplug and connect the UPS to the genny so that it has an
incoming 240v supply from which to recharge - you can run the genny
for a few hours to recharge the UPS, then off for another few hours,

The UPS is a good idea, although I would just stick it inline between the
FCU/isolator and the wiring centre, not sure it would consider the genny
feed as 'in-spec' power.

One point with the sort of UPS for PCs such as the APC ones, are they won't
power something from cold.
That is, if you've got one charged up but not plugged in, then just plug an
item into one of the outlets you won't get any power provided. If it's
receiving a mains input and you subsequently remove it, then the power is
maintained at the outlets.
