Permissions and groundwork in Gravesend
In Gravesend, work on adopted pavements and verges needs consent from Kent County Council, the local highway authority. Car parks, forecourts and other private land only need the owner's permission.
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 (the council for Gravesham) first — we flag this at survey.
Buried services across the entrance are traced and the position adjusted if needed, as the cassette cannot simply be made shallower. 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.
- Warn users and passers-by that the post rises on its own; fit reflective bands and consider a sign at busy sites.
- Keep clear gaps of typically at least 1,000–1,200 mm where pedestrians pass between posts, referring to Inclusive Mobility guidance.
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.
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.
Options to consider
| Option | Detail |
|---|---|
| Head lighting | Some models include battery or solar LEDs in the head to improve visibility on unlit sites. |
| 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. |
What affects the quote
When we price semi-automatic bollards in Gravesend, these make the biggest difference:
- Surface reinstatement
- Excavation depth and services in the way
- Drainage method
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 Gravesend are later hit or damaged, we can repair or replace them — see bollard repairs.
Common questions
Do you install semi-automatic bollards in Gravesend?
We cover all of Gravesend (DA12, DA11 and DA13) and the rest of Kent. We also work in Strood, Dartford and Rochester.
Do I need consent for semi-automatic bollards on a public footway in Gravesend?
The highway authority for local roads in Gravesend is Kent County 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.
What's a typical price for semi-automatic bollards in Gravesend?
In Gravesend, 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.
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.
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.
