Permissions and groundwork 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.
Many private-land installations in Thornhill need no planning application, but the rules don't clearly cover bollards, so listed buildings, conservation areas and prominent frontages are worth raising with the planning team at Cardiff Council before posts go in.
Clay soils and high water tables mean a gravel base alone will not drain the cassette; a connection to a surface water drain or a separate soakaway is then needed, and foul drains are not used. Reinstatement matches the drive, whether block paving, tarmac, resin-bound or imprinted concrete.
- Confirm the bollard is on your land; bollards on a public footway or dropped kerb need the highway authority's agreement.
- If the drive is shared, agree positions and keys with the other users first.
Installation, step by step
Check depth and drainage
The free site survey checks how far down we can dig, where services run under the drive and how the ground drains. If water will stand, a drain connection is priced into the fixed written quote.
Form the drainage
A gravel soakaway is placed beneath the cassette, or a pipe is laid to a surface water drain or new soakaway.
Reinstate and test
The surface is made good to match. The post is raised, locked, lowered and locked several times to confirm smooth operation, and keys are handed over.
Options to consider
| Option | Detail |
|---|---|
| Lid and head designs | Flush hinged lids, removable caps or integrated heads that close the cassette top when lowered. |
| Standard or lift-assisted | Lift-assisted models use a spring or counterweight so the post rises with little effort, useful for daily domestic use. |
| Diameter and height | Commonly around 90–140 mm diameter and 600–900 mm raised height, with larger posts for commercial use. |
What affects the quote
Our Wales guide prices are a starting point; the survey in Thornhill firms them up. What tends to move them:
- Post size and whether lift assistance is wanted
- Drainage: simple soakaway or a connection to a drain
- Stainless or powder-coated finish
Keeping them working
Lower and raise the bollard regularly, even if you rarely need to, so the mechanism stays free. If the post becomes stiff or will not lower fully, the usual causes are debris in the cassette or a blocked drain, both of which are easier to fix early than after the post has seized.
If posts in Thornhill are later hit or damaged, we can repair or replace them — see bollard repairs.
Common questions
Do you install telescopic bollards in Thornhill?
We cover all of Thornhill (CF14) and the rest of Cardiff. We also work in Caerphilly, Cardiff and Risca.
Do I need consent for telescopic bollards on a public footway in Thornhill?
In Thornhill the highway authority for local roads is Cardiff Council. We confirm whether the ground is adopted highway before quoting, because telescopic bollards on a public footway need its agreement first.
What's a typical price for telescopic bollards in Thornhill?
In Thornhill, typically £335–£1,145 per bollard with cassette, supplied and installed, plus VAT (£395–£1,345 including VAT for homeowners), with a minimum job of £625 plus VAT, using our Wales guide prices. The fixed figure comes in writing after we've seen the site.
Can a telescopic bollard be fitted into a resin or imprinted drive?
Yes, though the cut has to be made cleanly and the surface patched around the lid. Resin and imprinted finishes are hard to match exactly, so we plan positions to keep visible patching small.
Will a telescopic bollard stop my car being stolen?
It adds a physical barrier that a thief has to defeat before driving away, which slows them down and makes the car a less attractive target. It is one layer of protection, not a complete answer to keyless car theft.
