Damp footwell - air con leak?

[Gromit2012]

Our passenger footwell is really damp from a water leak coming from the right hand side front corner as you look forwards in the van. A little bit in left hand side driver's footwell too. Hasn't rained in yonks and it's a Beach so we don't have a water tank to be leaking, so I'm assuming probably something to do with the air con? When we first parked up after an hour driving, it was dripping about once a second (see photo), now slowed down to very gradual. Any advice or tips? (Have looked at other posts but they all seem to be rain-related.) Thank you!

Update: fixed. If anyone has a similar problem, it was indeed the air con system. The drain which takes away the condensation was blocked. A five minute repair by Absolute VW, who are brilliant specialists based near the M1 in Derbyshire - v much recommend for any van work.
