I was watching 'Working Lunch' where it featured a guy turning his
modelling hobby into a business. The business was based in his attic
which was accessed solely by a pull-down ladder.
How illegal is this?

It's not
How much use can you put an attic to that only has a pull-down ladder
as access?

It will be classed as occasional use/storage, which doesn't require any
planning regs.
