What is included?
We design the falls first, then add channels only where they are needed, typically across a garage door, at the bottom of a drive sloping to the house, or where the drive meets the pavement. Where the rules require water to be dealt with on site, a soakaway or a permeable build is the usual answer.
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.
- Threshold drainage at doors and garages
- Linear channel drains with gratings rated for cars
- Soakaway crates or rubble soakaways where ground allows
- Levels survey and a falls plan
- Connection to an existing surface water gully where permitted
What the survey covers
- Levels of the pavement, kerb and drive
- Access and working space
- Where water collects now and where it can go
- Buried services near the crossing or channel
- Load ratings needed for covers and gratings
Rules for front drives in Gwent
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.
