Rubber Speed Bumps: £80–£300 Supply Cost
Prefabricated rubber speed bumps are the most popular choice for private roads, car parks, and industrial estates. Made from recycled rubber or virgin EPDM, they bolt directly to the existing surface — no groundworks required.
Types of Rubber Speed Bump
- Bolt-down modular bumps: 75mm height, 900mm–3,000mm wide in bolt-together sections (£80–£200 per module)
- Wide-profile speed humps: 1,750–1,800mm wide (front-to-back) — gentler traverse for faster approach speeds (£150–£400)
- Speed cushions: Narrower raised sections leaving gaps for cycles and emergency vehicles (£200–£600 per set)
DIY vs Professional Installation
DIY installation: Most rubber speed bumps can be self-installed with a hammer drill and resin anchors. Budget £20–£50 for fixings plus the bump cost. Allow 2–4 hours for a pair of experienced installers.
Professional installation: A contractor will typically charge £50–£150 for a standard bump installation including labour, fixings, and waste disposal.
Asphalt Speed Humps: £700–£2,600 Installed
On adopted public highways, speed humps must generally be constructed in asphalt under the Highways (Road Humps) Regulations 1999. The hump profile, height (75mm maximum), length, and signing requirements are all prescribed by law.
Types of Asphalt Traffic Calming
- Standard hump (75mm high, 900–3,700mm long): Classic road hump. Effective at reducing speeds to 10–20mph at crossing point. Cost: £700–£1,500 installed.
- Speed cushion (75mm high, with gaps for emergency vehicles): Cost: £800–£2,000 per set installed.
- Raised table/platform: Flat-topped hump covering larger area. Cost: £2,500–£9,500 installed depending on size.
Planning Permission for Speed Bumps
On Adopted Public Highways
Speed humps on public roads require formal approval under The Highways (Road Humps) Regulations 1999. The process involves:
- Application to the highway authority (local council highways department)
- Formal consultation (28-day minimum) with emergency services, bus operators, and statutory undertakers
- Traffic Regulation Order if speed limit is to be formally reduced
- Approval and programme of works
This typically takes 3–12 months and adds £2,000–£8,000 in fees and consultant costs.
On Private Land
On private roads, car parks, and industrial estates, planning permission is generally not required. Check lease/freehold restrictions and consider signage as good practice even on private land.
Factors Affecting Speed Bump Cost
- Surface type: Soft tarmac is easier to drill than reinforced concrete
- Road width: Wider roads require more modules
- Traffic management: If traffic must be managed during installation, costs rise significantly
- Location: London and South East carry a 15–25% labour premium
- Quantity: Installing multiple humps in one visit is proportionally cheaper
Whole-Life Cost: Rubber vs Asphalt
