Just scrounge a bit of their green ducting and lay it in the ground
where you, want it to run. Just make sure the route is not too
tortuous and include some sort of draw wire inside, so they can use it
to pull their cable through the duct.

I did just that when I was having the drive done. Ran a 4" duct under
it from the side of the road up to the outside of the lounge window
where there is an air brick. Then had the good luck to meet the NTL
surveyor who was marking the pavement prior to installing the ducting
for cable. Not only got him to mark a spot next to my duct for his
access but also to put in an extra one for the annexe. When the install
guy arrived he was quite happy, very happy in fact, to use my duct. So
was I, no way was he going to cut up my new tarmac!!
