Consents, ground and services in Derry/Londonderry
Kerbside work in Derry/Londonderry 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.
Planning in Northern Ireland sits with the councils, so for a listed building or conservation area in Derry/Londonderry the planning team at Derry City and Strabane District Council is the one to ask before posts go in.
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.
- Agree how emergency services will gain access if the post is locked up.
- Warn users and passers-by that the post rises on its own; fit reflective bands and consider a sign at busy sites.
From survey to handover
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.
Options to consider
| Option | Detail |
|---|---|
| Lock types | Keyed cylinder locks, typically operating at ground level, with keyed-alike options for multi-post sites. |
| Head lighting | Some models include battery or solar LEDs in the head to improve visibility on unlit sites. |
| Duty level | Light-duty domestic models and heavier commercial versions with stronger cassettes and posts. |
What affects the quote
Two Derry/Londonderry jobs with the same number of posts can price quite differently. The usual reasons:
- Domestic or commercial duty model
- Drainage method
- Excavation depth and services in the way
After installation
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. 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.

Do you install semi-automatic bollards in Derry/Londonderry?

Do I need consent for semi-automatic bollards on a public footway in Derry/Londonderry?
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 Derry/Londonderry need its agreement before anything is dug. Posts on your own land do not.
What's a typical price for semi-automatic bollards in Derry/Londonderry?
In Derry/Londonderry, 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.
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.
