Semi-automatic bollards in Barnet: common uses
Typical reasons Barnet sites choose semi-automatic bollards:
- Driveways where the owner wants minimal effort
- Locations where automatic bollards are not justified
- Delivery entrances without a power supply nearby
What we check first in Barnet
The highway authority for local roads in Barnet is Barnet Council; motorways and trunk roads sit with National Highways. Red routes are managed by Transport for London. Semi-automatic bollards on the adopted footway are a matter for the highway authority, so we only install there with its written agreement.
Many private-land installations in Barnet 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 Barnet Council before posts go in.
Reinstatement around the collar has to be firm, because the post is pushed down by foot and any movement in the surround soon shows as cracking. 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.
Installation, step by step
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.
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.
Options to consider
| Option | Detail |
|---|---|
| Head lighting | Some models include battery or solar LEDs in the head to improve visibility on unlit sites. |
| Lock types | Keyed cylinder locks, typically operating at ground level, with keyed-alike options for multi-post sites. |
| Duty level | Light-duty domestic models and heavier commercial versions with stronger cassettes and posts. |
What affects the quote
Our London guide prices are a starting point; the survey in Barnet firms them up. What tends to move them:
- Excavation depth and services in the way
- Surface reinstatement
- Number of posts and keyed-alike locks
Keeping them working
In winter, keep an eye on the lid after frost or snow; ice around the head can stop the post rising, and forcing the key or the post at that point damages the latch. Operate the bollard regularly and keep the head and lid clear of grit.
If posts in Barnet are later hit or damaged, we can repair or replace them — see bollard repairs.

Do I need consent for semi-automatic bollards on a public footway in Barnet?
In Barnet, work on adopted pavements and verges needs consent from Barnet 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.
How much do semi-automatic bollards cost in Barnet?
In Barnet, 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.
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.
