If it’s just for access, I’d expect ~£1k depending on how many lifts required. If you want the roof handrailed, significantly more.
My site is complicated though, it’s probably cheaper for residential but you’ll pay VAT.
A cherry picker would be significantly cheaper if there is access.
Anyone got an idea how much a roof inspection via scaffolding should cost?
Got a roofer coming tomorrow and no costs have been mentioned yet and I'm hoping any such bill is reasonable. But how much is reasonable?
