I've decided to gove Sodium Chlorate a go. Do you have any idea
whether I should apply it once the shoots have started to appear or if
perhaps, applying some right now might prevent the shoots appearing at
all?

Are you sure you want to render your soil unusable for a whole season?
I doubt that sodium chlorate on its own will do the job either.

Moving house is probably easier for a quick fix.

The trouble is this...

The problem patch is under my patio slabs and grows up inbetween them
making access to the roots rather difficult. The bits in the lawn and
in the borders I can live with! I'm only planning on pouring the SC
down the gaps between the slabs, keeping my distance from the lawn of
course.

In those specific circumstances it might just work. But it is rather
water soluble and inclined to migrate sideways so be wary near the lawn
edge.

And the coy warning on the package "may promote combustion" needs to be
taken seriously. Do not get it onto wooden fence or decking.

But hitting them regularly with just about any weed killer ought to do
it if they are mostly trapped under concrete paving. You need to lop all
the tops off for a couple of seasons (eg by strimming regularly).
