Typical crash-rated bollards jobs in Potters Bar

Before we dig in Potters Bar
In Potters Bar, work on adopted pavements and verges needs consent from Hertfordshire County Council, the local highway authority. Car parks, forecourts and other private land only need the owner's permission.
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 Hertsmere) first — we flag this at survey.
Made ground, a high water table or soft clay may need an engineer to confirm the tested design suits the site; any change to depth, width or reinforcement must be agreed in writing by the manufacturer, or the rating may no longer apply. Utility records, radar scanning and hand-dug trial holes come before any machine work, and service diversions can take longer than the bollard installation itself.
- Check that the test certificate matches the exact model, configuration and foundation being installed, and keep it with the site records.
- Balance the gaps: narrow enough to stop a vehicle, typically no more than about 1,200 mm, but wide enough for wheelchair users and buggies — check against Inclusive Mobility guidance.
What happens on site
Start from the specification
We work from the specification issued by your security adviser or the manufacturer: product, rating, positions and foundation drawing. If no specification exists yet, we can put you in touch with the manufacturer's technical team, but we do not set the threat level ourselves.
Set out and excavate
Positions are set out to the drawing and excavated to the tested depth and width, with shoring where the ground needs it. Spoil is removed as work progresses.
Fix reinforcement and set the posts
The reinforcement cage is built to the drawing and the bollards are held to line and level in templates. Concrete is poured to the specified grade, with samples taken for testing if the specification calls for them.
Finishes and options
| Option | Detail |
|---|---|
| Finishes and visibility bands | Galvanised and powder-coated finishes in RAL colours, with contrasting or reflective bands near the top so the posts are visible to pedestrians and drivers. |
| Heights and diameters | Exposed heights are commonly around 800 to 1,000 mm, with core diameters varying by model and rating. Larger diameters are not always needed to achieve a given rating. |
| Rated removable or automatic posts | Where an entrance must open for deliveries or emergency vehicles, rated removable, retractable or automatic models are available. Check that the rating stated is for the exact model and position you are buying. |
What affects the quote
Two Potters Bar jobs with the same number of posts can price quite differently. The usual reasons:
- Number of posts and whether a linked beam system is needed
- Reinstatement of natural stone, tactile paving or specialist surfaces
- Covers, finishes and any integrated lighting
Keeping them working
Look for cracked surfacing at the base, movement, damaged covers and faded bands. Movable rated bollards need a planned servicing schedule.
If posts in Potters Bar are later hit or damaged, we can repair or replace them — see bollard repairs.
Crash-rated bollards in Potters Bar: FAQs
Do you install crash-rated bollards in Potters Bar?
We cover all of Potters Bar (EN6) and the rest of Hertfordshire. We also work in Borehamwood, Enfield and Hatfield.
Who gives permission for bollards on the pavement in Potters Bar?
Hertfordshire County Council is the highway authority covering Potters Bar's local roads. If any post would stand on adopted highway rather than your land, that consent is the first thing we sort out.
How much do crash-rated bollards cost in Potters Bar?
In Potters Bar, typically £2,295–£11,495 per bollard, supplied and installed on a standard tested foundation, plus VAT, with a minimum job of £4,595 plus VAT, using our London guide prices. The fixed figure comes in writing after we've seen the site.
What happens if a rated bollard is struck?
Make the area safe and have the post assessed before relying on it again. A rated bollard that has absorbed a serious impact is usually replaced, and the manufacturer may need to check the foundation or insert. We can install the replacement to the original tested detail.
Is a heavy unrated steel post good enough instead?
Not where the risk is a deliberate vehicle attack. An unrated post may look solid, but nobody can say what it will stop because it has never been tested with its foundation. Unrated steel suits nuisance parking and low-speed knocks, not crowds or buildings flagged in a security assessment.
