Consents, ground and services in St Albans
The highway authority for local roads in St Albans is Hertfordshire 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.
If your site in St Albans is listed or inside a conservation area, check with the local planning authority (the council for St Albans) before choosing a finish — heritage settings often favour cast iron or painted steel over stainless.
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. Because the cassette houses both the post and its strut mechanism, the pit is deep and must stay dry.
- Keep clear gaps of typically at least 1,000–1,200 mm where pedestrians pass between posts, referring to Inclusive Mobility guidance.
- Agree how emergency services will gain access if the post is locked up.
What happens on site
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.
Specification choices
| Option | Detail |
|---|---|
| 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. |
| Lock types | Keyed cylinder locks, typically operating at ground level, with keyed-alike options for multi-post sites. |
What moves the price in St Albans
Two St Albans jobs with the same number of posts can price quite differently. The usual reasons:
- Domestic or commercial duty model
- Excavation depth and services in the way
- Surface reinstatement
After installation
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 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.
If posts in St Albans are later hit or damaged, we can repair or replace them — see bollard repairs.

How is a semi-automatic bollard different from an automatic one?
An automatic bollard is powered and controlled by a panel, loops and access devices. A semi-automatic one rises on its own when unlocked but must be pushed down by hand. It needs no electrics, which keeps installation simpler.
Why has my semi-automatic bollard stopped rising fully?
Usually because the gas strut has lost pressure, or debris and water in the cassette are slowing it. Check and clean the cassette first. If it still stops short, the strut needs replacing.
