Before we dig in Letchworth Garden City
The highway authority for local roads in Letchworth Garden City 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.
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 North Hertfordshire) first — we flag this at survey.
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. 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.
- Agree how emergency services will gain access if the post is locked up.
- Check land ownership; bollards on public highway need the highway authority's agreement.
How the job runs
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.
Test and show users
The post is cycled several times to check it rises fully, locks at both heights and lowers smoothly. Users are shown how to operate it and to keep clear of the head when it rises.
Choosing the right spec
| Option | Detail |
|---|---|
| Finishes | Galvanised and powder-coated or stainless steel, with reflective bands for visibility. |
| Duty level | Light-duty domestic models and heavier commercial versions with stronger cassettes and posts. |
| Head lighting | Some models include battery or solar LEDs in the head to improve visibility on unlit sites. |
Pricing semi-automatic bollards in Letchworth Garden City
When we price semi-automatic bollards in Letchworth Garden City, these make the biggest difference:
- Number of posts and keyed-alike locks
- Domestic or commercial duty model
- Excavation depth and services in the way
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.
We can also service, repair or replace existing posts anywhere in Letchworth Garden City.

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.
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.
