Consents, ground and services in Thornhill
In Thornhill the highway authority for local roads is Cardiff Council. We confirm whether the ground is adopted highway before quoting, because driveway security posts on a public footway need its agreement first.
Bollards on private land often don't need planning permission, but it depends on the council's view, the height and the location; in a conservation area, next to a listed building or under an Article 4 direction, ask the local planning authority (Cardiff Council) first — we flag this at survey.
Clay soils hold water, so a telescopic or semi-automatic cassette there needs a proper soakaway or a connection to a surface water drain, never the foul drain. We scan and hand-dig before cutting deep for a telescopic cassette.
- In conservation areas or at listed buildings, check with the local planning authority before fitting visible posts.
- Connect any cassette drainage to surface water or a soakaway, not to the foul drain.
Installation, step by step
Free home survey
We look at your drive, how and where you park, the surface and what might be under it, such as the water pipe or a gas service. You receive a fixed written quote with the post type and position marked.
Fit the post
Telescopic cassettes and removable sockets are set flush in concrete with drainage beneath. Fold-down posts are anchored to concrete or a small new pad.
Make good and show you
The surface is reinstated and cleaned. We show you how to lock, lower and raise the post and hand over the keys.
Finishes and options
| Option | Detail |
|---|---|
| Telescopic posts | Retract into a cassette with a flush lid when lowered. Tidy and secure, but need depth and drainage under the drive. |
| Fold-down posts | Hinged posts bolted down with resin anchors. Quick to fit and no digging, but need a solid base to fix into. |
| Removable posts | Lift out of a shallow socket and lock in place. Simple and low cost to fit, but must be stored when out. |

Do I need two posts for two cars?
Not always. On a narrow drive where one car parks behind the other, one post at the front may be enough. On a wide drive with cars side by side, two posts are usually needed to block both.
Does a driveway post stop keyless car theft?
It cannot stop a thief opening or starting the car electronically, but it stops the car being driven off the drive until the post is unlocked. That makes your car a slower, riskier target. Use it alongside a signal-blocking pouch and the car's own security.
