Consents, ground and services in Gerrards Cross
The highway authority for local roads in Gerrards Cross is Buckinghamshire Council; motorways and trunk roads sit with National Highways. Semi-automatic bollards on the adopted footway are a matter for the highway authority, so we only install there with its written agreement.
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 (Buckinghamshire Council) first — we flag this at survey.
Because the cassette houses both the post and its strut mechanism, the pit is deep and must stay dry. Buried services across the entrance are traced and the position adjusted if needed, as the cassette cannot simply be made shallower.
- Check land ownership; bollards on public highway need the highway authority's agreement.
- Warn users and passers-by that the post rises on its own; fit reflective bands and consider a sign at busy sites.
How the job runs
Survey use and ground
At the free site survey we look at how often the post will be used, who will operate it and what is under the surface. A fixed written quote follows, including drainage.
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.
Test and show users
The post is cycled several times to check it rises fully, locks at both heights and lowers smoothly. Users are shown how to operate it and to keep clear of the head when it rises.
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. |
| Height and diameter | Raised heights commonly around 500–900 mm and diameters around 100–200 mm, depending on model and duty. |
Pricing semi-automatic bollards in Gerrards Cross
Our South East guide prices are a starting point; the survey in Gerrards Cross firms them up. What tends to move them:
- Drainage method
- Domestic or commercial duty model
- Excavation depth and services in the way
Looking after them
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. Watch the rising speed: when it slows or the post no longer reaches full height, the strut is losing pressure and should be replaced before it fails altogether.
For damaged or loose posts in Gerrards Cross, repairs and replacements are priced in writing first.

What's a typical price for semi-automatic bollards in Gerrards Cross?
In Gerrards Cross, typically £1,145–£3,695 per bollard, supplied and installed, plus VAT (£1,345–£4,445 including VAT for homeowners), with a minimum job of £1,245 plus VAT, using our South East guide prices. The fixed figure comes in writing after we've seen the site.
What makes a semi-automatic bollard rise without power?
A gas strut or spring inside the cassette. Pushing the post down compresses it and a latch holds the post below ground. Turning the key releases the latch and the stored energy lifts the post.
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.
