Site constraints 2

National infrastructure project 574 m away: M4 Junctions 3 to 12 Smart Motorway
The site is 574 m from the project boundary. Highway, decided. The project page says whether consent was granted. Also within 2 km: Slough Multifuel Extension Project (decided, 1618 m).
Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.

Checked on 6 October 2026. Historic England, the Environment Agency, Natural England, the Planning Inspectorate and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
