strung together this:

I think he said it was a 'Clipseal'

Clipsal

one? It has a little hinged
sideways opening door and seems water restistant (rubber seals
everywhere).

1 x RCD (30A? 30mA)
1 x 16 MCB
1 x 6 MCB.

If I was to get the Screwfix one for *my* garage could I replace the
16A MCB for a 32A one?

Yep, assuming you've got the correct power into the unit and a 40A
RCD, you can change it. I'd check what you've got though, Clipsal do
25A and 40A units.
I've found that Proteus, (CEF's own brand), MCB's fit the Clipsal
garage units if the Clipsal MCB's prove troublesome to source.
