Consents, ground and services in Thornhill
Local roads and pavements in Thornhill are the responsibility of Cardiff Council as highway authority, with the Welsh Government's trunk road agents handling trunk roads. Posts on the public highway need that authority's consent; private land does not.
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.
Turf around new posts is reinstated and, on sites used by mowers, posts are spaced so equipment can pass. Timber bollards usually go into soft landscape, so the ground varies more than with paved sites.
- Check whether the verge is highway land; posts there usually need the highway authority's agreement.
- Keep emergency vehicle access available, using a removable or hinged post where a route must open.
Installation, step by step
Survey the setting
A free site survey looks at the ground, drainage, tree roots, how vehicles currently get onto the land and how the site looks. You receive a fixed written quote with species, size and fixing.
Set the posts
Posts are set plumb and to a consistent height, backfilled with compacted stone or concreted with a shaped top. Cut softwood ends are re-treated.
Finish and tidy
Reflective bands are fitted, turf is reinstated around the posts and spoil is removed or spread as agreed.
Specification choices
| Option | Detail |
|---|---|
| Tropical hardwood | Very dense and long-lasting in ground contact. Specify certified sustainable sources. |
| Fixing methods | Direct burial in compacted stone, set in concrete with a shaped collar, or mounted on a steel shoe or socket. |
| Oak | Naturally durable heartwood that weathers to silver-grey. Suits parks, heritage settings and visible frontages. |
What affects the quote
Two Thornhill jobs with the same number of posts can price quite differently. The usual reasons:
- Fixing method: stone, concrete or steel shoe
- Number of posts and length of the line
- Post size and length
Keeping them working
Inspect posts at ground level, where rot starts, by probing for soft wood. Re-treat cut or damaged softwood, keep grass and soil from building up around the base, and replace posts that are soft at the ground line before they snap.
For damaged or loose posts in Thornhill, repairs and replacements are priced in writing first.
Timber bollards in Thornhill: FAQs
Which parts of Thornhill do you cover for timber bollards?
We cover all of Thornhill (CF14) and the rest of Cardiff. We also work in Caerphilly, Cardiff and Risca.
Who gives permission for bollards on the pavement in Thornhill?
Local roads and pavements in Thornhill are the responsibility of Cardiff Council as highway authority, with the Welsh Government's trunk road agents handling trunk roads. Posts on the public highway need that authority's consent; private land does not.
How much do timber bollards cost in Thornhill?
In Thornhill, typically £95–£335 per post, supplied and installed, plus VAT (£105–£395 including VAT for homeowners), with a minimum job of £425 plus VAT, using our Wales guide prices. The fixed figure comes in writing after we've seen the site.
Why is my new oak bollard cracking?
Oak shrinks as it dries, and surface checks and splits are a normal part of that. They rarely affect the post's strength. Deep splits that run right through, or soft wood at the base, are a different matter.
Do timber bollards stop vehicles?
They stop most drivers deliberately mounting a verge and resist low-speed knocks, especially in dense hardwood. They are not tested barriers and should not be relied on against a vehicle driven at them deliberately.
