What we check first in Trowbridge
Wiltshire Council is the highway authority covering Trowbridge's local roads. If any post would stand on adopted highway rather than your land, that consent is the first thing we sort out.
Many private-land installations in Trowbridge 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 Wiltshire Council before posts go in.
Because the cassette houses both the post and its strut mechanism, the pit is deep and must stay dry. On sandy or gravel ground a soakaway beneath the cassette often drains it adequately; on clay, chalk with poor drainage or where groundwater rises, a pipe to a surface water drain or a dedicated soakaway is needed.
- Keep clear gaps of typically at least 1,000–1,200 mm where pedestrians pass between posts, referring to Inclusive Mobility guidance.
- Agree how emergency services will gain access if the post is locked up.
Installation, step by step
Excavate the pit
The surface is cut and the pit dug to the cassette depth plus a drainage layer, by hand near services.
Set the cassette
The cassette is set plumb and flush with the finished surface, connected to drainage and concreted in. The strut is fitted or released only as the manufacturer instructs.
Reinstate the surface
Paving or surfacing is made good tight to the cassette collar so there is no lip for tyres or feet to catch.
Choosing the right spec
| Option | Detail |
|---|---|
| Lock types | Keyed cylinder locks, typically operating at ground level, with keyed-alike options for multi-post sites. |
| Head lighting | Some models include battery or solar LEDs in the head to improve visibility on unlit sites. |
| Duty level | Light-duty domestic models and heavier commercial versions with stronger cassettes and posts. |
Pricing semi-automatic bollards in Trowbridge
Our South West guide prices are a starting point; the survey in Trowbridge firms them up. What tends to move them:
- Finish and any head lighting
- Number of posts and keyed-alike locks
- Domestic or commercial duty model
Looking after them
Look into the cassette periodically for water or debris, and lubricate the lock and latch as the manufacturer suggests. If several posts on one site were installed at the same time, their struts tend to wear at a similar rate, so it can make sense to replace them together.
We can also service, repair or replace existing posts anywhere in Trowbridge.

Who gives permission for bollards on the pavement in Trowbridge?
In Trowbridge, work on adopted pavements and verges needs consent from Wiltshire Council, the local highway authority. Car parks, forecourts and other private land only need the owner's permission.
How much do semi-automatic bollards cost in Trowbridge?
In Trowbridge, typically £1,095–£3,495 per bollard, supplied and installed, plus VAT (£1,295–£4,195 including VAT for homeowners), with a minimum job of £1,195 plus VAT, using our South West guide prices. The fixed figure comes in writing after we've seen the site.
Why has my semi-automatic bollard stopped rising fully?
Usually because the gas strut has lost pressure, or debris and water in the cassette are slowing it. Check and clean the cassette first. If it still stops short, the strut needs replacing.
Is it hard to push the bollard back down?
Not usually; most users press it down with a hand or foot. The strut resists, so it needs a steady push rather than a sharp kick. Heavier commercial models take more effort than domestic ones.
