Before we dig 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.
Historic streets were built in layers: modern services sit over older drains, coal holes and sometimes vaults, and the paving may be natural stone on a lime or sand bed rather than concrete. Original stone flags and setts are reused wherever possible, because new stone rarely matches weathered material.
- Agree contrasting paint details with the conservation officer so posts remain visible to partially sighted people, in line with Inclusive Mobility guidance.
- On public highway, agree positions and specification with the highway authority.
What happens on site
Record what is there
The free site survey records existing bollards, their pattern, spacing, height and condition, and the paving they sit in. You receive a fixed written quote covering new castings, resets and reinstatement.
Lift paving carefully
Natural stone flags, setts and kerbs are lifted by hand, numbered where needed and stored for relaying.
Relay and finish
Stone is relaid in its original pattern with suitable mortar, and the bollard is painted or touched up after fixing.
Options to consider
| Option | Detail |
|---|---|
| Ductile iron | Same patterns with much greater toughness; bends before it breaks. The usual choice for new posts on trafficked streets. |
| Paint finishes | Primed and painted, commonly black, with traditional highlights in gold or white on bands and crests where appropriate. |
| Contrast details | Painted bands or contrasting caps agreed with the conservation officer so posts are visible to partially sighted people. |
