What we check first in Hounslow
Hounslow Council is the highway authority covering Hounslow's local roads. Red routes are managed by Transport for London. If any post would stand on adopted highway rather than your land, that consent is the first thing we sort out.
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 (Hounslow Council) first — we flag this at survey.
Buried services across the entrance are traced and the position adjusted if needed, as the cassette cannot simply be made shallower. On sandy or gravel ground a soakaway beneath the cassette often drains it adequately; on clay, chalk with poor drainage or where groundwater rises, a pipe to a surface water drain or a dedicated soakaway is needed.
- Check land ownership; bollards on public highway need the highway authority's agreement.
- Warn users and passers-by that the post rises on its own; fit reflective bands and consider a sign at busy sites.
From survey to handover
Excavate the pit
The surface is cut and the pit dug to the cassette depth plus a drainage layer, by hand near services.
Set the cassette
The cassette is set plumb and flush with the finished surface, connected to drainage and concreted in. The strut is fitted or released only as the manufacturer instructs.
Reinstate the surface
Paving or surfacing is made good tight to the cassette collar so there is no lip for tyres or feet to catch.
Choosing the right spec
| Option | Detail |
|---|---|
| Gas strut or spring assist | Most models use a gas strut; some use springs. Both store energy to raise the post when unlocked. |
| Lock types | Keyed cylinder locks, typically operating at ground level, with keyed-alike options for multi-post sites. |
| Height and diameter | Raised heights commonly around 500–900 mm and diameters around 100–200 mm, depending on model and duty. |
What affects the quote
Two Hounslow jobs with the same number of posts can price quite differently. The usual reasons:
- Excavation depth and services in the way
- Drainage method
- Number of posts and keyed-alike locks
After installation
Look into the cassette periodically for water or debris, and lubricate the lock and latch as the manufacturer suggests. Operate the bollard regularly and keep the head and lid clear of grit.
We can also service, repair or replace existing posts anywhere in Hounslow.

Can a semi-automatic bollard injure someone as it rises?
It rises with some force, so nobody should stand over it or put a hand on the head when releasing it. Users should be shown how to operate it safely. On busy sites, a sign and reflective bands help.
Why has my semi-automatic bollard stopped rising fully?
Usually because the gas strut has lost pressure, or debris and water in the cassette are slowing it. Check and clean the cassette first. If it still stops short, the strut needs replacing.
