Almost certainly, but you'll need to call us as soon as you are aware you'll need the van longer!
In most cases we are able and happy to do this, we'll adjust your payments accordingly which we'll settle up with you when you return the vehicle. (Don't forget this may affect excess waiver payments too!)
Very rarely we may have to refuse*, in which case we'd ask that the van is returned at the agreed time.
*We would only refuse if we need the vehicle back for another customer and no other vehicles are available.
