Planning and drainage go together

For front gardens, whether you need planning permission can depend on whether water drains to a lawn or border on your property, or the surface lets water through. The design must also protect your home and the road.

02 / 06

Measure all the water that arrives

Your drive may take water from paths, roofs, next door or a slope above. Look at the whole area that drains onto it, not just the new paving.

Door levels set the limits

Garage and front door thresholds, the damp-proof course and the pavement edge decide how much slope you have. Channels only work if they have an outlet, enough capacity and can be cleaned.

04 / 06

Permeable paving needs the right base

Wider joints over a solid base do not make paving permeable. The base layer, bedding, edging and ground below must all let water through.

Do not assume a soakaway will work

The position, how fast the ground drains, groundwater and space all need checking. If the ground will not take water, you may need a storage tank or another approved route.

06 / 06

Keep rainwater on your property

Finished levels should stop water running onto the pavement, road or next door. Check this at design stage and again before the final surface goes down.

Driveway Drainage Rules in Surrey

Questions about driveway drainage rules

Straight answers before you commit. If yours is not here, ask us directly.

01

Do I need planning permission for a new driveway?

It depends on the size, where the water drains and any other limits. The Planning Portal and your local council set out the rules.

02

Can a channel drain empty onto the road?

No. A channel only collects water. It needs a proper, legal outlet. Sending water onto the road is not an acceptable plan.

03

Does a resin-bound surface always let water through?

Only if the whole build-up lets water through and deals with it. A permeable-looking surface on a solid or unsuitable base may not drain.
