Before we dig in Potters Bar
The highway authority for local roads in Potters Bar 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 Potters Bar is listed or inside a conservation area, check with the local planning authority (the council for Hertsmere) before choosing a finish — heritage settings often favour cast iron or painted steel over stainless.
Buried services across the entrance are traced and the position adjusted if needed, as the cassette cannot simply be made shallower. 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.
- Check land ownership; bollards on public highway need the highway authority's agreement.
- Keep clear gaps of typically at least 1,000–1,200 mm where pedestrians pass between posts, referring to Inclusive Mobility guidance.
How the job runs
Excavate the pit
The surface is cut and the pit dug to the cassette depth plus a drainage layer, by hand near services.
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.
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. |
| Lock types | Keyed cylinder locks, typically operating at ground level, with keyed-alike options for multi-post sites. |
| Gas strut or spring assist | Most models use a gas strut; some use springs. Both store energy to raise the post when unlocked. |
What moves the price in Potters Bar
Two Potters Bar jobs with the same number of posts can price quite differently. The usual reasons:
- Drainage method
- Domestic or commercial duty model
- Surface reinstatement
Looking after them
Do not try to dismantle the strut assembly without the right procedure, as it holds stored energy. Operate the bollard regularly and keep the head and lid clear of grit.
For damaged or loose posts in Potters Bar, repairs and replacements are priced in writing first.

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.
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.
