What we check first in Sevenoaks
The highway authority for local roads in Sevenoaks 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.
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 Sevenoaks) first — we flag this at survey.
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. Because the cassette houses both the post and its strut mechanism, the pit is deep and must stay dry.
- Check land ownership; bollards on public highway need the highway authority's agreement.
- Keep clear gaps of typically at least 1,000–1,200 mm where pedestrians pass between posts, referring to Inclusive Mobility guidance.
How the job runs
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.
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.
Finishes and options
| 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. |
| Height and diameter | Raised heights commonly around 500–900 mm and diameters around 100–200 mm, depending on model and duty. |
| Duty level | Light-duty domestic models and heavier commercial versions with stronger cassettes and posts. |
Pricing semi-automatic bollards in Sevenoaks
When we price semi-automatic bollards in Sevenoaks, these make the biggest difference:
- Surface reinstatement
- Finish and any head lighting
- Number of posts and keyed-alike locks
After installation
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.
For damaged or loose posts in Sevenoaks, repairs and replacements are priced in writing first.
Common questions
Can you install semi-automatic bollards anywhere in Sevenoaks?
We cover all of Sevenoaks (TN13, TN14 and DA4) and the rest of Kent. We also work in Tonbridge, Bromley and Swanley.
Do I need consent for semi-automatic bollards on a public footway in Sevenoaks?
In Sevenoaks, 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.
How much do semi-automatic bollards cost in Sevenoaks?
In Sevenoaks, 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.
Do semi-automatic bollards suit domestic driveways?
Yes, if the owner wants less lifting than a telescopic post. The same depth and drainage checks apply. Domestic models are lighter duty than commercial ones.
