M25 junction 10
Upgrading this stretch of road will provide vital improvements to its safety and reliability. At the same time, this scheme will involve some of the most extensive environmental mitigation ever carried out by National Highways, with more than 16 hectares of land being used to replace the common land / public open space that is needed to improve the junction.
Our proposals will improve connections, smooth traffic flows and create safer journeys for all.
We are proposing four new slip roads for the M25 junction 10 roundabout, meaning traffic turning left can pass through the junction easily.
The M25 will increase from three to four lanes through the junction, with the A3 also becoming four lanes either side of the junction 10 roundabout. There will also be improvements to the A245, Sevenhills junction and Painshill roundabout.
Around the junction, there will be new and safer routes for pedestrians, cyclists and horse riders. Improvements will also be made to the local environment and wildlife.
These changes will improve safety, reduce traffic, smooth the flow of traffic and improve journey times. The new junction will improve almost 300,000 journeys a day, making them more reliable and safer, with nearly a third fewer collisions.
Our environmental work will leave a lasting legacy of improvements to the surrounding environment to be enjoyed for years to come.
The scheme will involve some of the most extensive environmental mitigation ever carried out by National Highways.
Around the junction we’ll be replacing lost habitats, restoring heathland and planting woodland. These works will be phased over several years. Find out more on our Habitats factsheet.
We’ll also be improving the water environment, including Boulder Mere and the Stratford Brook. You can find out more on our Water Environment factsheet.

Consultation documents 2017
The Development Consent Order (DCO) process was established by the Planning Act 2008 and is used for certain large and complex schemes (including highway improvements) that have been designated as a Nationally Significant Infrastructure Project (NSIP) by the Government.
The Secretary of State for Transport granted the Development Consent Order (DCO) for the M25 junction 10/A3 Wisley interchange improvements on 12 May 2022. Links to key DCO documentation can be found below:
- Examining Authority’s report and recommendations to the Secretary of State for Transport
- Secretary of State for Transport’s decision letter and statement of reasons
- Development Consent Order as made by the Secretary of State for Transport
You can view our full Development Consent Order application on the Planning Inspectorate website.
Current scheme plans and documents are listed at Article 45 in Schedule 11.
Development Consent Order – Requirements Register
Requirements are planning conditions included in the DCO that relate to all or part of the works. They each require documents to be prepared, consulted upon by defined organisations and submitted to the Secretary of State for approval. These processes are referred to here and in the DCO as “discharging” the requirements.
This Requirements Register is a live document and will be updated as the process to discharge the requirements progresses.
The latest version will always be published below:
This register will be maintained for three years following completion of the project. The register sets out:
- each requirement
- whether the requirement needs approval by the Secretary of State (or other duty holder)
- whether any approval has been applied for or given
- Requirement 3 – Construction environmental management plan
- Requirement 4 – Traffic management during construction
- Requirement 7 – Design, layout and implementation of Replacement Land
- Requirement 8 – Thames Basin Heaths Special Protection Area (SPA) Compensatory Habitat Creation and Enhancement Areas
- Requirement 14 – Archaeology
