Permissions and groundwork in Derry/Londonderry
Across Northern Ireland the Department for Infrastructure's DfI Roads is the roads authority, so steel security bollards on a public footway or road in Derry/Londonderry need its agreement before anything is dug. Posts on your own land do not.
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.
Root-fixed posts need firm ground and enough depth to carry the post's root plus a concrete surround. Reinstatement matches the surface, whether tarmac, block paving, flags or turf.
- Do not describe unrated posts as anti-ram or HVM protection in risk assessments or to insurers.
- Fit contrasting or reflective bands near the top so posts are visible, as Inclusive Mobility guidance recommends.
How the job runs
Break out and excavate
For root-fixed posts, the surface is cut neatly and each hole is dug to depth, by hand near known services. For base plates, the slab is checked for thickness and soundness.
Fill and cap
Where specified, posts are filled with concrete and capped so water cannot collect inside the tube.
Reinstate and finish
The surface around each post is made good to match, and reflective bands are fitted. Damaged galvanising from handling is touched up.
Options to consider
| Option | Detail |
|---|---|
| Concrete infill | Adds mass and stiffness and makes the post harder to cut or dent. Usually specified for security and impact positions. |
| Caps and heads | Dome, flat, chamfered or ball tops, with welded caps to keep water out of hollow posts. |
| Root-fixed | Cast into a concrete foundation, typically with several hundred millimetres of post below ground. The usual choice where digging is possible. |
What moves the price in Derry/Londonderry
Our Northern Ireland guide prices are a starting point; the survey in Derry/Londonderry firms them up. What tends to move them:
- Tube diameter, wall thickness and concrete infill
- Number of posts and length of the line
- Ground conditions and buried services
Looking after them
A post that leans after a knock usually means the foundation has moved or cracked; it should be re-bedded or replaced rather than left as a trip or snag hazard. Reflective bands fade and peel and are easy to renew.
If posts in Derry/Londonderry are later hit or damaged, we can repair or replace them — see bollard repairs.

Which parts of Derry/Londonderry do you cover for steel security bollards?

Do I need consent for steel security bollards on a public footway in Derry/Londonderry?
In Derry/Londonderry, as everywhere in Northern Ireland, public roads and footways are looked after by DfI Roads rather than the council. If a post would sit on adopted footway, that consent comes first; private forecourts and car parks are a matter for the owner.
What's a typical price for steel security bollards in Derry/Londonderry?
In Derry/Londonderry, typically £195–£875 per bollard, supplied and installed, plus VAT (£225–£1,045 including VAT for homeowners), with a minimum job of £575 plus VAT, using our Northern Ireland guide prices. The fixed figure comes in writing after we've seen the site.
Should I choose root-fixed or base-plated steel bollards?
Root-fixed where you can dig and want the stronger post; base-plated where there is a sound slab and you want quick installation or the option to remove posts later. Base plates are limited by the slab and anchors, so they are not the right choice where vehicles hit hard.
Why fill a steel bollard with concrete?
Concrete infill adds weight and stiffness, so the post dents less and is harder to cut. It also stops water collecting inside a hollow tube. It is usual for security and impact positions.
