Permeable block paving in Swanley: the local picture
Swanley is a smaller town, and many of its homes have more frontage to work with than city houses, which leaves room for borders and planting.
Planning-sensitive towns and conservation areas are common in the South East, so we check the front-garden rules before quoting.
How much does a permeable block drive cost in Swanley?
In the South East, a permeable block drive usually costs £115–£185 per m² including VAT. For a 50 m² drive, that is roughly £5,650–£9,200. Your exact price depends on what the survey or your photos show, and is fixed in writing before anything is booked.

What does a permeable block drive involve?
It is the straightforward way to pave a front garden without sending rain into the road, which matters because in England a non-permeable front surface over 5 m² that does not drain to a permeable area within the property needs planning permission, and in Wales any new front surface must be permeable or drain within the property. The build is different from a standard drive from the ground up, so it has to be designed as permeable rather than just using different blocks.
- Grit laying course and permeable blocks with grit-filled joints
- Open-graded crushed stone (no fines) laid and compacted in layers
- Deeper dig-out for the open-graded sub-base
- Geotextile layer where the design needs one
- Ground check: how well the soil drains and how high the water table sits
What the survey covers
- Block range, thickness, colour and pattern to suit the house
- Existing manhole and inspection covers, and whether to recess them
- Whether front-garden planning rules apply
- Where rain will go: falls, lawn, border, channel or soakaway
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
Do you need permission in Swanley?
Swanley is in England, so these rules apply:
In England, paving in front of the house that covers more than 5 m² needs planning permission unless it is permeable or drains to a lawn, border or soakaway inside your boundary. Permeable block paving, or standard blocks laid to fall onto a planted strip, avoid the need for permission in most cases.
Flats and maisonettes, listed buildings, and homes covered by an Article 4 direction can have tighter rules, and conservation areas, National Parks and National Landscapes restrict some permitted development.
A dropped kerb needs your local highway authority's approval (usually the county, unitary, metropolitan or London borough council), and a new access onto an A, B or C classified road also needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
