Don't worry, the UK will increase road and fuel tax to fix them
I've noticed here in Luxembourg they're taking a bit longer to come out to repair some holes, but generally it's still only a few days if the location is a dangerous spot.
I actually reported one the other week to the bus company where they had resurfaced the road alongside the bus shelter, but the parts surrounding a couple of man covers had sunk causing quite large dips (not really a pot-hole, but just as bad). When it was raining cars where simply soaking anyone standing in the shelter - including me when I didn't realise. Two days later it was fixed.
