What is SUDS Compliance?
A Complete Guide to Sustainable Drainage for Driveways & Patios
Have you ever noticed how quickly water builds up on roads or driveways during heavy rain? As more homes and developments replace grass and soil with hard surfaces like concrete and tarmac, the risk of flooding in urban areas continues to grow. That’s where Sustainable Drainage Systems (SUDS) come in.
SUDS compliance is all about managing water in a smarter, more natural way. It reduces the pressure on the existing drainage network, helps avoid flooding, and keeps surface water under control, especially on driveways, patios, and front gardens.
But what exactly does it mean to be SUDS compliant? And how can you make sure your property meets these drainage requirements??
What is SUDS?
SUDS stands for Sustainable Drainage Systems. These systems are designed to mimic natural processes, meaning they let rainwater soak into the ground slowly, just like it would if the surface were grass or soil.
Standard driveways made from concrete or asphalt don’t allow water through. Instead, they send water straight into the sewers, which can lead to blockages, overflow, and flooding.
SUDS solutions help avoid these problems by managing surface water runoff more effectively.
How SUDS Benefits Driveways
- Reduces the impact of heavy rainfall by slowing water flow
- Helps avoid flooding by easing pressure on the local drainage network
- Filters out pollutants, improving water quality
- Minimises maintenance, as permeable surfaces reduce standing water and weed growth
- Can add value to your home by offering a modern, eco-conscious upgrade
SUDS-Compliant Materials for Driveways
Several types of permeable paving meet SUDS guidelines. These include:
- Resin-bound surfacing – attractive, durable and fully permeable
- Permeable blocks – small gaps allow water to drain through
- Porous asphalt – allows water to pass through its open structure
- Gravel or crushed stone – a traditional permeable option (can shift without edging)
Some homes also combine SUDS driveways with green roofs, rain gardens, or swales to further support water management across the property.
Why Resin Bound Driveways Are a Top Choice
Resin-bound drivewaysare one of the most effective and visually appealing SUDS-compliant options. Here’s why:
- Fully Permeable – Water flows through the surface into the ground below
- Durable – Designed to handle regular use without cracking or breaking
- Low Maintenance – Smooth finish prevents weed growth and puddles
- Aesthetic Appeal – Comes in a range of colours and styles to suit your home
- Space Efficient – Ideal forfront gardens under 5 (avoiding planning permission in many cases)
Resin Bound vs Resin Bonded, What the Difference?
| Driveway Type | SUDS Compliant | Why |
|---|---|---|
| Resin Bound | Yes | Fully permeable; allows water to drain through |
| Resin Bonded | No | Sealed surface; prevents water infiltration |
Resin bound systems mix stone and resin before laying, creating a breathable surface. Resin bonded systems spread resin first, then apply stones on top — which seals the surface and prevents water from soaking in.
Do You Need Planning Permission?
In many cases,SUDS-compliant driveways don’t require planning permission, especially if:
- The area is less than 5 square metres
- Any runoff drains into a permeable area, like a lawn or soakaway
However, if you’re using non-permeable materials like concrete, tarmac, or resin-bonded surfacing, you may need permission, especially in urban areas where water has fewer places to go/
Choosing the Right Contractor
Installing a SUDS-compliant surface properly is key. Make sure your installer:
- Has experience with resin-bound systems or other permeable options
- Uses quality, UV-stable resin that won’t fade or crack
- Follows SUDS best practices to support local water management
