Parking while away?

I live near the edge of the controlled parking zone and usually leave my car just outside of it, in a place that’s not inconveniencing anyone (I’m not directly outside anyone’s home). Not had issues but I do regularly check on it and have had to move it a couple times where cones have been put up around it.

I’m going away for 2 weeks and so I’m mainly a little concerned what happens if this occurs while I’m not here, I assume the car gets towed but if it’s for something like roadworks etc. would I still be subject to a £300 fine as if I’d just left it in the middle of princes street?
