The Legal Requirement: Section 184 Highways Act 1980
It is an offence under Section 184(1) of the Highways Act 1980 to habitually drive a motor vehicle across a public footway or verge unless an approved vehicular crossing has been constructed.
The standard pavement footway is built only to sustain pedestrian loadings (typically 50mm asphalt or concrete slabs over weak sub-base). Repeated vehicular overrun without a reinforced crossing fractures buried statutory utility apparatus (gas mains, water pipes, fibre optic cables) and creates pedestrian tripping hazards for which the adjoining homeowner can be held civilly liable.
An approved crossing replaces standard paving with heavy-duty tarmacadam or concrete laid over reinforced DOT Type 1 sub-base, flanked by taper transition kerbs.
Do You Need Planning Permission for a Dropped Kerb?
Whether you need planning permission depends primarily on the legal classification of the highway:
• Unclassified Roads (Permitted Development): Under Schedule 2, Part 2, Class B of the Town and Country Planning (General Permitted Development) (England) Order 2015, constructing a vehicular access onto an unclassified residential street is permitted development. You only need a Section 184 licence from the highway authority.
• Classified Roads (A, B, or C Roads): If your property faces a classified road, trunk road, or primary dual carriageway, full planning permission is legally mandatory before applying for a highway crossover licence.
• Flats, Listed Buildings & Conservation Areas: Permitted development rights do not apply to subdivided buildings, maisonettes, or properties subject to Article 4 directions restricting hardstanding.
• Front Garden Paving Drainage: Under Class F of the GPDO, paving more than 5 square metres of your front garden requires planning permission unless the surface is made of porous material (such as permeable block paving or gravel) or directs runoff to an internal garden border.
| Road Classification | Planning Permission Required? | Section 184 Licence Required? | Approval Timeline |
|---|---|---|---|
| Unclassified Residential Street | No (Class B Permitted Development) | Yes (Highways Authority) | 4 to 8 weeks |
| Class C Highway | Yes (Local Planning Authority) | Yes (Highways Authority) | 8 to 12 weeks |
| Class B or Class A Primary Route | Yes (Strict visibility splay inspection) | Yes (Highways Authority) | 10 to 16 weeks |
| Conservation Area / Article 4 | Yes (Heritage assessment mandatory) | Yes (Highways Authority) | 8 to 14 weeks |
Physical Criteria: Driveway Depth, Visibility Splays & Street Furniture
Highway authorities will reject applications that fail to meet strict geometric criteria:
• Minimum Driveway Depth: The distance between the front wall of your house (or bay window) and the boundary must measure at least 4.8 metres (5.0 metres in many councils, and 5.5m in London). This ensures standard family vehicles fit entirely within private curtilage without overhang.
• Minimum Width: The driveway entrance must usually span at least 2.4 to 3.0 metres clear of pillars or walls.
• Street Furniture Clearance: Dropped kerbs must maintain statutory clearance from highway assets: minimum 1.5m from lamp columns, 1.0m from inspection covers/gullies, and 1.5m to 2.0m from trees. Relocating a council lamp post or telegraph pole can add £1,500 to £4,000 to project costs.
Complete Cost Breakdown (2026 Figures)
The total expenditure to drop a kerb consists of three distinct components:
1. Council Application & Inspection Fee: £150 to £450 (non-refundable technical assessment by highway engineer).
2. Planning Application Fee (if classified road): £258 statutory fee in England.
3. Physical Construction by NRSWA-Accredited Contractor: £1,000 to £2,500 depending on width (standard 3-kerb crossing vs wide 5-kerb crossing) and pavement depth.
Total project cost typically sits between £1,400 and £3,200. Beware that in some councils (such as Birmingham, Leeds, and several London boroughs), works must be carried out exclusively by the council's direct labour organisation (DLO).
