What is included?
Drainage for block paving makes sure rain leaves the surface in a controlled way: falls in the paving direct it, channel drains collect it across openings, and a soakaway or approved connection takes it away. Standard block paving sheds most of its rain, so a drive without a plan for the water ends up with puddles, wet thresholds or water running onto the pavement.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.
- Soakaway crates or rubble soakaways where ground allows
- Linear channel drains with gratings rated for cars
- Threshold drainage at doors and garages
- Connection to an existing surface water gully where permitted
- Levels survey and a falls plan
What the survey covers
- Load ratings needed for covers and gratings
- How the new work ties into the paving
- Access and working space
- Who must approve the work and how long that takes
- Levels of the pavement, kerb and drive
Rules for front drives in West Glamorgan
In Wales, any new or replacement hard surface at the front of a house should be permeable or drain to a permeable area within the property to avoid needing planning permission. Unlike England, there is no 5 m² allowance for new paving; only repairs of up to 5 m² of existing surface are exempt.
Since January 2019, construction work covering 100 m² or more with drainage implications, including drives and patios, needs approval from the local SuDS Approving Body (SAB) before work starts, even where planning permission is not needed.
A dropped kerb needs your council's approval as highway authority, and a new access onto a classified road needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
