Sustainable Drainage in Hampshire: How a Permeable Driveway Keeps You Compliant
If you are replacing a driveway anywhere in Hampshire, sustainable drainage is one of the first things worth understanding — it decides whether you need planning permission and how your property copes with heavy rain. A resin-bound driveway is fully permeable and SuDS-compliant, priced at £65–£110 per m² fully installed and covered by our 10-year installation guarantee.
The Rules Behind SuDS — and Why They Matter Locally
The Sustainable Drainage Systems rules were introduced in 2008 to stop rainwater from impermeable driveways overwhelming public drains and causing flash flooding. In practice they mean that a new front driveway over 5m² must either use a permeable surface or drain to a soft area within your boundary. Across Hampshire — where clay soils in towns like Alton and Totton hold water, and coastal districts like Havant sit at low elevation — this is more than red tape: poorly drained driveways are a real contributor to surface water flooding after storms.
How Water Actually Moves Through a Resin-Bound Surface
A resin-bound driveway is not sealed like tarmac. The mix of aggregate and UV-stable resin leaves an open matrix of tiny voids, so rainwater drains straight down through the surface into a free-draining sub-base and then into the ground. Nothing pools, nothing runs off, and there is no need for a soakaway or drainage channel on most Hampshire sites. This is completely different from resin-bonded surfaces, which look similar but seal the base and shed water — and stones — like any impermeable finish.
Flood Risk, Article 4 Areas and When to Check With the Council
For the vast majority of Hampshire homeowners a permeable driveway needs no planning permission, because SuDS compliance places it under permitted development. The exceptions to watch for are listed buildings and conservation areas carrying an Article 4 direction, common in historic centres like Winchester, Petersfield and Wickham. If your home sits in an Environment Agency flood zone near the Test, Itchen or the Solent coast, a SuDS-compliant surface is the sensible specification — it keeps rainfall on your own land instead of adding to the problem downstream.
Frequently Asked Questions
Is a resin-bound driveway automatically SuDS-compliant?
Yes, when installed correctly over a permeable, free-draining sub-base. The open matrix of a resin-bound surface allows water to drain through it, which is exactly what SuDS requires.
Do I still need planning permission if my driveway is permeable?
Generally no. A permeable front driveway falls under permitted development in Hampshire. Only listed buildings and Article 4 conservation areas need a check with the local authority first.
Does SuDS compliance add cost to a Hampshire driveway?
Rarely. Because the whole surface drains, most projects avoid extra drainage works, keeping the price within £65–£110 per m² fully installed.
