On or over the public highway: A scaffold that occupies or encroaches over a road or pavement needs a licence from the relevant highway authority. The proposal may also need arrangements for people passing the site. Tell the scaffold supplier about the pavement, verge, parking and any overhang, even when the planned work is on your own building.
Wholly within private space: A highway scaffold licence may not be relevant, but that does not settle land access, planning or safety duties. Confirm the proposed position with the supplier; a paved area may still be highway.
Who applies?
Government guidance says the builder or scaffolding company is responsible for getting a highway licence for scaffold they put up there, and the customer should check that it is in place and covers the period of the work. Ask your chosen supplier who will apply and how the licence and any conditions affect the proposed dates and quote.
