Consents, ground and services 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.
If your site in Welwyn Garden City is listed or inside a conservation area, check with the local planning authority (the council for Welwyn Hatfield) before choosing a finish — heritage settings often favour cast iron or painted steel over stainless.
Duct routes cross the carriageway and often the footway, so buried services along those routes must be traced first. The pit base is usually connected to a surface water drain or a soakaway, and on clay or high water table sites that connection needs particular attention.
- Have the electrical installation carried out and certified by a qualified electrician to BS 7671.
- For rated units, keep the test certificate and confirm the foundation matches the tested design.
How the job runs
Survey and risk assessment
A free site survey covers traffic patterns, who uses the entrance, power, drainage routes and buried services. We draft the safety arrangement from that, and you receive a fixed written quote.
Excavate and set cassettes
Each cassette pit is excavated to the manufacturer's depth, with the base prepared to drain. Cassettes are set to finished road level and fall, then concreted in.
Power and controls
A qualified electrician installs the supply and isolation, and the controller, traffic lights, photocells and access devices are mounted and wired.
Choosing the right spec
| Option | Detail |
|---|---|
| Electro-mechanical drive | Motor and gearbox inside the bollard with no hydraulic fluid. Often simpler to service, with duty cycles that suit moderate traffic. |
| Heights and diameters | Raised heights are commonly around 500–800 mm for traffic control and taller for security models, with diameters varying by drive and rating. |
| Unrated or crash-rated | Unrated units control traffic; rated units are tested to IWA 14-1, ISO 22343-1 or PAS 68 for security entrances, with deeper, heavier foundations. |

Why do automatic bollards need drainage?
The bollard sits in a pit that collects rain and silt. Without a drain, water corrodes the mechanism, short-circuits electrics and can freeze the post in place. A drain connection is part of every automatic installation we carry out.
How will emergency vehicles get through?
Usually by an agreed method such as a fire service key switch, a code, a remote handset held by the site or a free-exit arrangement. It should be agreed with the emergency services before the bollards go live.
