Semi-automatic bollards in Greenwich: common uses
Common uses in a place like Greenwich:
- Sites where telescopic posts are too heavy for regular users
- Private roads and courtyards with a small number of key holders
- Driveways where the owner wants minimal effort
Consents, ground and services in Greenwich
Greenwich Council is the highway authority covering Greenwich's local roads. Red routes are managed by Transport for London. 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 Greenwich 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 Greenwich Council before posts go in.
Buried services across the entrance are traced and the position adjusted if needed, as the cassette cannot simply be made shallower. 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.
- Agree how emergency services will gain access if the post is locked up.
- Warn users and passers-by that the post rises on its own; fit reflective bands and consider a sign at busy sites.
Installation, step by step
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.
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.
Specification choices
| Option | Detail |
|---|---|
| Gas strut or spring assist | Most models use a gas strut; some use springs. Both store energy to raise the post when unlocked. |
| Finishes | Galvanised and powder-coated or stainless steel, with reflective bands for visibility. |
| Height and diameter | Raised heights commonly around 500–900 mm and diameters around 100–200 mm, depending on model and duty. |
What affects the quote
Our London guide prices are a starting point; the survey in Greenwich firms them up. What tends to move them:
- Drainage method
- Number of posts and keyed-alike locks
- Surface reinstatement
Looking after them
Operate the bollard regularly and keep the head and lid clear of grit. 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.
If posts in Greenwich are later hit or damaged, we can repair or replace them — see bollard repairs.

Do you install semi-automatic bollards in Greenwich?

Who gives permission for bollards on the pavement in Greenwich?
In Greenwich, work on adopted pavements and verges needs consent from Greenwich Council, the local highway authority. Red routes are managed by Transport for London. Car parks, forecourts and other private land only need the owner's permission.
What's a typical price for semi-automatic bollards in Greenwich?
In Greenwich, typically £1,245–£3,995 per bollard, supplied and installed, plus VAT (£1,495–£4,795 including VAT for homeowners), with a minimum job of £1,345 plus VAT, using our London 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.
Can a semi-automatic bollard injure someone as it rises?
It rises with some force, so nobody should stand over it or put a hand on the head when releasing it. Users should be shown how to operate it safely. On busy sites, a sign and reflective bands help.
