What Welwyn Garden City sites use crash-rated bollards for

- Transport interchanges, taxi ranks and drop-off zones
What we check first in Welwyn Garden City
In Welwyn Garden City, 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.
Many private-land installations in Welwyn Garden City need no planning application, but the rules don't clearly cover bollards, so listed buildings, conservation areas and prominent frontages are worth raising with the planning team at the council for Welwyn Hatfield before posts go in.
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. Rated foundations are large, and excavation is often where projects run into trouble.
- Ask the local planning authority whether consent is needed, particularly in conservation areas or near listed buildings.
- 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.
Free site survey and ground checks
A free site survey looks at access, surfaces and likely services, followed by utility searches, radar scanning and trial holes where needed. You then receive a fixed written quote based on what the survey found.
Cure, protect and reinstate
The posts are protected while the concrete gains strength, and the surface is reinstated to match. The line should not be treated as fully effective until the specified curing period has passed.
Finishes and options
| Option | Detail |
|---|---|
| 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. |
| Decorative covers | Stainless steel, cast or polymer sleeves can be fitted over the steel core to suit a streetscape. Use covers supplied or approved by the manufacturer so the tested product is not altered. |
| Static rated bollards | Fixed posts for permanent lines where vehicles never need to pass. They are a straightforward rated option to install and maintain. |
Pricing crash-rated bollards in Welwyn Garden City
Our East of England guide prices are a starting point; the survey in Welwyn Garden City firms them up. What tends to move them:
- Number of posts and whether a linked beam system is needed
- Depth and volume of excavation, reinforcement and concrete
- Buried services, diversions and ground investigation
Looking after them
Look for cracked surfacing at the base, movement, damaged covers and faded bands. Static rated bollards need little routine work, but they should be inspected periodically and always after any impact.
If posts in Welwyn Garden City are later hit or damaged, we can repair or replace them — see bollard repairs.
Questions about crash-rated bollards in Welwyn Garden City
Which parts of Welwyn Garden City do you cover for crash-rated bollards?
We cover all of Welwyn Garden City (AL8, AL7 and AL6) and the rest of Hertfordshire. We also work in Hatfield, Hertford and Harpenden.
Do I need consent for crash-rated bollards on a public footway in Welwyn Garden City?
The highway authority for local roads in Welwyn Garden City is Hertfordshire County Council; motorways and trunk roads sit with National Highways. Crash-rated bollards on the adopted footway are a matter for the highway authority, so we only install there with its written agreement.
What's a typical price for crash-rated bollards in Welwyn Garden City?
In Welwyn Garden City, typically £2,045–£10,295 per bollard, supplied and installed on a standard tested foundation, plus VAT, with a minimum job of £4,095 plus VAT, using our East of England guide prices. The fixed figure comes in writing after we've seen the site.
What does a crash rating code actually tell me?
It tells you the vehicle used in the test, how fast it was travelling, the angle it hit at and how far it got past the bollard line. Your security adviser compares those figures with the vehicle and speed achievable on your approach. A rating that does not match the site's real risk is either more than you need or not enough.
Why can't the foundation be adjusted to suit our ground?
Because the rating belongs to the bollard and foundation as tested together. Making the hole shallower, narrower or lighter on steel changes how the system behaves on impact. If site conditions force a change, the manufacturer has to approve it in writing, and some changes mean choosing a different product such as a shallow-mount system.
