Before we dig in Hemel Hempstead
Hertfordshire County Council is the highway authority covering Hemel Hempstead's local roads. If any post would stand on adopted highway rather than your land, that consent is the first thing we sort out.
If your site in Hemel Hempstead is listed or inside a conservation area, check with the local planning authority (the council for Dacorum) 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. Buried services across the entrance are traced and the position adjusted if needed, as the cassette cannot simply be made shallower.
- Keep clear gaps of typically at least 1,000–1,200 mm where pedestrians pass between posts, referring to Inclusive Mobility guidance.
- Warn users and passers-by that the post rises on its own; fit reflective bands and consider a sign at busy sites.
What happens on site
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.
Choosing the right spec
| Option | Detail |
|---|---|
| Duty level | Light-duty domestic models and heavier commercial versions with stronger cassettes and posts. |
| Height and diameter | Raised heights commonly around 500–900 mm and diameters around 100–200 mm, depending on model and duty. |
| Finishes | Galvanised and powder-coated or stainless steel, with reflective bands for visibility. |
What moves the price in Hemel Hempstead
When we price semi-automatic bollards in Hemel Hempstead, these make the biggest difference:
- Number of posts and keyed-alike locks
- Drainage method
- Excavation depth and services in the way
Keeping them working
Look into the cassette periodically for water or debris, and lubricate the lock and latch as the manufacturer suggests. 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 Hemel Hempstead are later hit or damaged, we can repair or replace them — see bollard repairs.
Common questions

How much do semi-automatic bollards cost in Hemel Hempstead?
In Hemel Hempstead, typically £1,145–£3,695 per bollard, supplied and installed, plus VAT (£1,345–£4,445 including VAT for homeowners), with a minimum job of £1,245 plus VAT, using our South East guide prices. The fixed figure comes in writing after we've seen the site.
Can a semi-automatic bollard injure someone as it rises?
It rises with some force, so nobody should stand over it or put a hand on the head when releasing it. Users should be shown how to operate it safely. On busy sites, a sign and reflective bands help.
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.
