I've been offered a yard to house my timber kiln, it is adjacent to a
road with an electricity supply and I'm deciding whether to go with a
generator 11 hours a day or the grid supply. SEEboard deem it a
business connection and are asking for details of welders, motors,
cranes etc. as well as the total load (about 15kW(e)max) before they
will quote.

They are wanting to know how much surge capacity you need.
I assume it's mostly a refrigeration plant, to do water removal?
Those can use quite large amounts of electricity.
If its insulated very well ~500mm, I would imagine you could do most of
the heating, from recovering waste heat.
