Planning permission is one of the first things people ask us about. The good news is that most driveways don’t need it. The rules are about rainwater, not the driveway itself: councils want to stop water running off paved front gardens into the drains and the road.
What are the rules in England?
Chester, Ellesmere Port, Frodsham, Neston and the whole of the Wirral are in England. Here, according to the Planning Portal, you don’t need planning permission for a new or replacement driveway of any size if:
- it uses a permeable (porous) surface, such as permeable block paving, resin bound or gravel, or
- the rainwater is directed to a lawn or border so it can soak away naturally.
You do need planning permission if the driveway is more than 5m², uses a traditional non-permeable surface like standard tarmac or concrete, and the water has nowhere to drain except the road.
What are the rules in Wales?
Deeside, Buckley, Mold, Flint and the rest of Flintshire are in Wales, where the Welsh Government’s rules are stricter. To lay or replace a hard surface at the front of the house without planning permission, you must use permeable materials, or direct the run-off from a non-permeable surface to a permeable area at the front of the home.
The 5m² figure in Wales only applies to repairing or replacing existing hard surfacing, such as fixing a pothole or replacing a few slabs. It doesn’t give you a 5m² allowance for a new non-permeable driveway.
What about SuDS approval in Wales?
Wales has a separate system called SuDS (sustainable drainage) approval. The Welsh Government says SAB applications are required by law for construction work adding up to 100m² or more where it affects how the ground absorbs rainwater. Driveways, patios and parking areas can count towards that total.
Most single driveways are well under 100m², but big drives, or a driveway and patio built together, can get close. SAB approval is separate from planning and can be needed even when planning permission isn’t. If you’re unsure, check with Flintshire County Council’s SuDS Approving Body before work starts.
Which surfaces count as permeable?
| Surface | Permeable? | Notes |
|---|---|---|
| Resin bound | Yes | Water drains through the resin and into the base. |
| Permeable block paving | Yes | Looks like standard block paving but with wider joints and a free-draining base. |
| Gravel | Yes | Permeable, but loose stones can move, especially on slopes. |
| Standard block paving | Not usually | Fine if the water drains onto a lawn or border. |
| Tarmac | No (standard) | Fine if the water drains onto a lawn or border, or into a soakaway. |
| Imprinted concrete | No | Needs drainage to a permeable area. |
When might you need planning permission anyway?
Even with a permeable surface, check with your council if:
- you live in a flat or maisonette (permitted development rights apply to houses only),
- the house is listed or in a conservation area,
- a planning condition or Article 4 direction has removed your permitted development rights,
- you’re raising or terracing the ground significantly, or
- you need a new dropped kerb, especially on an A, B or C road. That’s a separate approval from the highways team. See our guide to getting a dropped kerb.
What we do on the survey
When we come out to measure up, we look at where the water will go and tell you whether your design is likely to need permission. Most of the time the answer is a permeable surface, or simple falls towards a lawn or border, and no application is needed.
This is general guidance based on the Planning Portal (England) and Welsh Government pages. Rules can change, so if you’re in any doubt, check with your local council before work starts.
