Permissions and groundwork in Kensington and Chelsea
Kensington and Chelsea Council is the highway authority covering Kensington and Chelsea'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 Kensington and Chelsea 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 Kensington and Chelsea 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.
- Warn users and passers-by that the post rises on its own; fit reflective bands and consider a sign at busy sites.
- Check land ownership; bollards on public highway need the highway authority's agreement.
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.
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 |
|---|---|
| Gas strut or spring assist | Most models use a gas strut; some use springs. Both store energy to raise the post when unlocked. |
| 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. |
Pricing semi-automatic bollards in Kensington and Chelsea
When we price semi-automatic bollards in Kensington and Chelsea, these make the biggest difference:
- Number of posts and keyed-alike locks
- Finish and any head lighting
- Excavation depth and services in the way
Keeping them working
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. Look into the cassette periodically for water or debris, and lubricate the lock and latch as the manufacturer suggests.
For damaged or loose posts in Kensington and Chelsea, repairs and replacements are priced in writing first.

What's a typical price for semi-automatic bollards in Kensington and Chelsea?
In Kensington and Chelsea, 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.
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.
How is a semi-automatic bollard different from an automatic one?
An automatic bollard is powered and controlled by a panel, loops and access devices. A semi-automatic one rises on its own when unlocked but must be pushed down by hand. It needs no electrics, which keeps installation simpler.
