Driveway Drainage and SuDS Rules, Explained Simply

When you need planning permission for a driveway, when you don't, and how to stay the right side of the rules without spending more.

The rule in one paragraph

Since 2008, you need planning permission to lay a non-permeable surface over 5m² in your front garden, unless the water drains to a permeable area within your own boundary. Permeable surfaces — resin bound, gravel, permeable block — are exempt regardless of size. That's genuinely the whole rule.

What counts as permeable

Resin bound is permeable. Resin bonded is not. Standard block paving is not, but permeable block paving with wider joints and a clean stone sub-base is. Tarmac is not permeable, so a tarmac front drive over 5m² needs either permission or somewhere for the water to go.

The cheap, legal way round it

You don't have to change surface. Falling the driveway towards a border, a soakaway or a permeable strip along one edge satisfies the rule perfectly well, and usually costs less than upgrading the whole surface. We design this in as standard — it's not an extra.

Why it matters beyond the paperwork

Rugby has a fair amount of clay subsoil, which drains slowly. A driveway that ponds will fail faster, ice over in winter and push water toward your damp course. Getting the drainage right is worth doing for your own sake, never mind the regulations.
