Oxford Street's pedestrianisation has moved from consultation into physical delivery, with statutory planning powers transferred to the Oxford Street Development Corporation and Transport for London now carrying out highway works ahead of the first section becoming traffic-free.
Updated 13 September 2026: This analysis was originally published in January 2026. It has been updated to reflect the transfer of planning powers to the Oxford Street Development Corporation, the Mayor's February transport decision and highway works beginning in September 2026.
The Oxford Street Development Corporation (OSDC) was established as a statutory Mayoral Development Corporation on 1 January 2026 under the Localism Act 2011 framework. What began as a proposal to change the governance and use of London's best-known shopping street is now operating through a dedicated delivery body with planning, regeneration and investment responsibilities. The change builds on the earlier consultation and development phase, but the position in September 2026 is materially different. Oxford Street is now partly governed through OSDC's statutory planning powers and partly through Transport for London's highway and traffic authority functions, creating a new delivery structure for construction, public realm, servicing and development across the corridor.
OSDC now controls planning across the development area
One of the most important changes since this article was first published is now complete. The Oxford Street Development Corporation became the local planning authority for the Mayoral Development Area on 10 August 2026, following the Oxford Street Development Corporation (Functions) Order 2026. Planning decision-making functions previously exercised by Westminster City Council and the London Borough of Camden within the OSDC boundary have therefore transferred to the corporation. OSDC also has plan-making responsibilities for the area and assumes a direct role in shaping development around Oxford Street. This is a significant operational distinction for developers and project teams. OSDC is not simply a promotional regeneration body: within its defined area it now performs statutory planning functions that directly affect future applications, development strategy and the relationship between private projects and the wider Oxford Street programme.
TfL controls the highway and traffic system
The planning transfer sits alongside an earlier change in highway governance. In September 2025, the Mayor approved the redesignation of Oxford Street from Marble Arch to the western arm of Tottenham Court Road as a GLA Road, together with changes affecting a number of adjoining streets. Transport for London consequently became highway authority and traffic authority for the relevant GLA Roads. That gives TfL responsibility for the road network measures needed to deliver the pedestrianisation and manage surrounding traffic, buses, access and temporary highway arrangements. The arrangement creates a clear division of functions: OSDC leads regeneration and planning within the development area, while TfL controls the strategic highway and traffic changes required to alter how Oxford Street operates. The original mayoral proposal for Oxford Street has therefore developed into a formal statutory and transport-delivery structure.
September works move the scheme into physical delivery
The Mayor formally approved the transport and highway changes required for the first pedestrianisation section on 26 February 2026. The mayoral decision directed TfL to take the statutory steps necessary to remove general traffic from Oxford Street between Great Portland Street and Orchard Street. That followed an eight-week TfL consultation running from 21 November 2025 to 16 January 2026 and covering traffic movements, buses, taxis, cycling and the wider effect of the proposed street changes.
Delivery has now reached the street. TfL states that works were anticipated from 2 September 2026, subject to the necessary approvals and consents, across Oxford Street, Regent Street, Bond Street and Great Portland Street. The programme includes temporary road closures, lane restrictions, diversions and changes to parking arrangements. TfL says works will be undertaken overnight where possible to reduce disruption, although some daytime activity will also be required. The current target is for the Oxford Street section between Orchard Street and Great Portland Street to become traffic-free by mid to late October 2026.

What the new servicing regime means for construction logistics
The operating environment will change substantially once Oxford Street West becomes traffic-free. TfL's current delivery and servicing guidance provides a daily access window from midnight to 07:00 for businesses between Great Portland Street and Orchard Street/North Audley Street. Outside that period there will be no delivery access onto Oxford Street West. The final operating arrangement is also intended to remove cars, buses, taxis, private-hire vehicles, cycles, scooters and pedicabs from the pedestrianised section, while emergency access will remain available.
For contractors working on Oxford Street itself or developments dependent on frontage access, this makes logistics planning more important. Delivery times, loading arrangements, temporary works, hoardings, utility access and traffic management will need to be coordinated with the operating restrictions of the pedestrianised corridor and the surrounding TfL-controlled road network. This does not mean every construction activity will automatically be limited to the midnight-to-07:00 servicing window. Individual construction works will remain subject to their own permissions, traffic-management arrangements, environmental requirements and project-specific logistics plans. The servicing regime should therefore not be treated as a universal construction-hours rule.
The £150m programme and what is actually being delivered
The first phase between Orchard Street and Great Portland Street is expected to cost around £150 million. OSDC budget material has identified approximately £144 million of capital expenditure to 2030–31 for delivery of the first pedestrianisation section, alongside associated revenue costs. City Hall has said the scheme is expected to be funded through a combination of public borrowing, private-sector fundraising, revenue generation and private contributions. The £150 million figure should therefore be understood as the approximate cost of the Phase One pedestrianisation programme rather than the value of a single construction contract.
This distinction is particularly important for the construction supply chain. The current September works concern the highway and operational changes needed to make Oxford Street traffic-free. They should not automatically be treated as the award or commencement of every permanent public-realm package within the wider capital programme. Earlier LCM coverage tracked the scheme as it moved through its design, consultation and statutory preparation stages. The September 2026 position is clearer: governance is established, planning powers have transferred, TfL controls the highway, the Mayor has authorised the traffic changes and implementation works are underway.
What happens next
TfL's immediate programme is focused on completing the road, bus and traffic changes required to make Oxford Street West traffic-free, with the current ambition to achieve that in mid to late October 2026. Beyond that operational change, OSDC will continue developing the permanent public-realm and wider regeneration programme. Further design, procurement and construction packages will need to progress through the corporation's governance and funding processes rather than being inferred from the £150 million programme headline alone. Oxford Street has therefore moved beyond the stage described when this analysis was first published in January. The statutory bodies are now in place, the planning and highway responsibilities are defined and physical implementation has begun. The next test is how quickly the temporary and operational changes can be converted into the permanent public realm envisaged for the wider Oxford Street transformation.
