Permissions and groundwork in Larne
Kerbside work in Larne is a DfI Roads question: the Department for Infrastructure is the roads authority for Northern Ireland, and its permission is needed for anything placed in the public road or footway.
Many private-land installations in Larne 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 Mid and East Antrim Borough 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.
- Keep clear gaps of typically at least 1,000–1,200 mm where pedestrians pass between posts, referring to Inclusive Mobility guidance.
What happens on site
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 |
|---|---|
| Height and diameter | Raised heights commonly around 500–900 mm and diameters around 100–200 mm, depending on model and duty. |
| Head lighting | Some models include battery or solar LEDs in the head to improve visibility on unlit sites. |
| Finishes | Galvanised and powder-coated or stainless steel, with reflective bands for visibility. |
What moves the price in Larne
When we price semi-automatic bollards in Larne, these make the biggest difference:
- Finish and any head lighting
- Number of posts and keyed-alike locks
- Excavation depth and services in the way
Looking after them
If several posts on one site were installed at the same time, their struts tend to wear at a similar rate, so it can make sense to replace them together. 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 Larne are later hit or damaged, we can repair or replace them — see bollard repairs.
Semi-automatic bollards in Larne: FAQs
Which parts of Larne do you cover for semi-automatic bollards?
We cover all of Larne (BT40) and the rest of Mid and East Antrim. We also work in Carrickfergus, Newtownabbey and Antrim.
Who gives permission for bollards on the pavement in Larne?
Across Northern Ireland the Department for Infrastructure's DfI Roads is the roads authority, so semi-automatic bollards on a public footway or road in Larne need its agreement before anything is dug. Posts on your own land do not.
How much do semi-automatic bollards cost in Larne?
In Larne, typically £1,095–£3,445 per bollard, supplied and installed, plus VAT (£1,295–£4,145 including VAT for homeowners), with a minimum job of £1,145 plus VAT, using our Northern Ireland guide prices. The fixed figure comes in writing after we've seen the site.
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.
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.
