My crit air cert came through a couple of days ago. Annoys me to admit it, but this French site seemed to work rather better than anything from the DVLA would - even the English was good.

As for file size, I scanned the V5 whatsit and then used the free graphics program Paint that comes with W10 to reduce file size.

Its not clear where in froggyland the cert is needed but for the small amount of money involved and because I didnt want frog marching ( see what I did there! ) off to a cash point for not having one when I should have one, I got one.
