What we check first in Welwyn Garden City
Hertfordshire County Council is the highway authority covering Welwyn Garden City's local roads. If any post would stand on adopted highway rather than your land, that consent is the first thing we sort out.
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.
Removing an old bollard often reveals more concrete than expected, because foundations from different eras vary widely in size. Breaking out is done carefully near services, particularly where cables have been laid close to posts since the original installation.
- Where bollards were required by a planning condition, a security plan or a lease, check that any change of type still meets that requirement.
- Keep gaps and visibility bands in line with Inclusive Mobility guidance when replacing posts on pedestrian routes.
Installation, step by step
Make safe
If a broken post or stub is a hazard, it can be removed or capped first. That is priced separately in writing so you can approve it on its own.
Remove the old bollard
The damaged post is cut or extracted and the old foundation broken out, checking for services as the hole is opened.
Hand over records
Photographs and an itemised invoice are provided, which is useful when recovering the cost from a driver's insurer.
Options to consider
| Option | Detail |
|---|---|
| Like-for-like | Same diameter, height, finish and fixing, so the line looks unchanged. |
| Heavier section | Larger diameter, thicker wall or concrete-filled steel where posts keep getting bent. |
| Crash-rated upgrade | Replacing unrated posts with tested products, installed to the manufacturer's foundation design and specified with your security adviser. |
What moves the price in Welwyn Garden City
Two Welwyn Garden City jobs with the same number of posts can price quite differently. The usual reasons:
- Upgrades that need larger foundations
- Surface type and reinstatement
- Number of posts and the product chosen
Keeping them working
A single impact on a rarely struck post is bad luck; repeated strikes in the same spot point to a layout problem, such as a tight turn or a missing wheel stop, that a stronger bollard alone will not solve. Keep a record of the new product, finish and supplier so future replacements match.
For damaged or loose posts in Welwyn Garden City, repairs and replacements are priced in writing first.

Do I need consent for bollards on a public footway in Welwyn Garden City?
Hertfordshire County Council is the highway authority covering Welwyn Garden City'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 replacement bollards cost in Welwyn Garden City?
In Welwyn Garden City, typically £225–£1,245 per post replaced, old post and footing removed, plus VAT (£265–£1,495 including VAT for homeowners), with a minimum job of £455 plus VAT, using our East of England guide prices. The fixed figure comes in writing after we've seen the site.
Should we replace like-for-like or upgrade?
Like-for-like if the post was hit once in an unusual incident. Consider an upgrade if the same position is struck repeatedly or the post no longer suits how the site is used. The survey will show which makes sense.
Can you replace just one bollard in a line?
Yes. We measure and match the existing posts so the new one sits in line at the same height and finish. If the original product is no longer made, we show you a close equivalent first.
