Hornchurch (East London Times) November 9, 2026 – Local residents and environmental campaigners gathered in Hornchurch on Saturday to stage a protest against plans for a massive 600-megawatt (MW) data centre campus slated for 200 hectares of Green Belt farmland in North Ockendon. The demonstration, held on 7 November 2026, formed part of a broader, coordinated pan-European action across 6 and 7 November demanding an immediate moratorium on new large-scale data centres. Campaigners are pressing Havering Council to reject a live Local Development Order (LDO) application for the scheme and open a fresh 12-week public consultation process to allow deeper community scrutiny.

Why Are Residents Protesting the East Havering Data Centre Campus?
The protest coincided with coordinated events organised across Europe to oppose the rapid expansion of resource-intensive digital infrastructure. As stated by organisers of the pan-European movement, approximately 101 groups in 15 countries planned demonstrations, local actions, and public events across the two-day period.
In Hornchurch, local opposition focused on the sheer scale of the East Havering proposal. According to descriptions provided by Havering Council, the project covers roughly 200 hectares of designated Green Belt farmland at North Ockendon. The proposed development comprises multiple data centre buildings, an indoor horticultural facility, a district heating network, an ecology park, and a visitors centre.
Havering Council has formally described the development as a campus, noting that it would be the largest facility of its kind in Europe and arguing that it would deliver a significant boost to the local economy.
What Is the Status of the Local Development Order Application?
Havering Council, acting in its capacity as the local planning authority, ran a public consultation on a draft LDO for the campus between 6 March and 12 April 2026. The draft LDO consultation had previously been approved by Havering’s Strategic Planning Committee on 3 March 2026, and the formal consultation period is currently closed.
As explained by the council, a Local Development Order functions as a specialized planning mechanism tailored for complex, large-scale development projects, establishing a predetermined planning framework for specified forms of development.
However, campaigners have voiced strong objections to the choice of an LDO as the consenting route. Opponents argue that relying on an LDO establishes a fixed framework that curtails the scope for rigorous, case-by-case scrutiny of individual buildings and infrastructure components. In response to these concerns, Havering Council has maintained that the LDO route provides a clear, structured planning framework designed to establish clear parameters that will guide all subsequent detailed proposals.
What Are the Key Concerns Raised by Campaigners and International Groups?
Demonstrators at Saturday’s event highlighted severe concerns regarding the loss of agricultural Green Belt land and the destruction of local wildlife habitats. Campaigners also cited an estimated carbon footprint of 1.2 million tonnes of CO2 per year generated by the complex, a figure derived from their own internal analysis which has not been independently verified.
As stated by a group spokesperson during the demonstration,
“We are calling for a moratorium on new large scale data centres, so we can have a proper democratic debate.”
The spokesperson, alongside fellow protesters, urged local councillors to formally reject the LDO application and initiate a fresh 12-week consultation period.
Highlighting the wider regional scale of the opposition, Owen Espley, coordinator of StopDirtyDataCentres.eu, stated that communities right across Europe are “challenging the imposition of energy, water and land hungry data centres.” Espley described Saturday’s collective demonstrations as an integral part of a growing international movement seeking to enforce strict limits on the scale and siting of such industrial digital infrastructure.
What Are the Next Steps for Havering Council and Local Residents?
The precise date on which Havering councillors will formally determine the LDO has not yet been confirmed by the local authority. Campaign material distributed by project opponents suggested that senior councillors would debate the matter during the week following the protest; however, this timeline remains unconfirmed by official council channels. Official attendance figures for Saturday’s demonstration have likewise not been published by authorities.
Throughout the planning process, Havering Council has emphasised the significant potential economic benefits of the campus, highlighting that supporters view the project as a major vehicle for bringing inward investment and long-term jobs to the borough. Conversely, opponents continue to press for an immediate halt to proceedings, demanding comprehensive public engagement and a national review of planning policies regarding data facilities.
With the draft LDO consultation period officially closed, the immediate focus for local campaign groups centers on persuading borough councillors to pause current legal proceedings and grant a new 12-week window for public scrutiny prior to any final decision.
Background of the North Ockendon Data Centre Proposal
The controversy surrounding the North Ockendon proposal comes amidst a major expansion of digital infrastructure across the United Kingdom and Europe, driven by rising demand for cloud computing and artificial intelligence processing power. Data centres of this magnitude require vast physical footprints, direct access to high-voltage national grid connections, and continuous cooling infrastructure, making outer London boroughs with available Green Belt land prime targets for commercial developers.
In the UK, planning policies surrounding the Metropolitan Green Belt have historically maintained a strict presumption against inappropriate development to prevent urban sprawl and preserve open countryside. However, the use of planning instruments such as Local Development Orders (LDOs) allows local planning authorities to grant outline planning permission for specific types of development across defined areas, streamlining the process for strategic economic investments. Havering Council’s introduction of the draft LDO in March 2026 was intended to position the borough as a primary hub for Europe’s tech infrastructure, balancing the loss of agricultural land against prospective long-term technological and commercial investment.
Predictions: How This Development Could Affect Key Stakeholders
Impact on Local Residents and Community Groups
If the LDO is approved in its current form without further public consultation, local residents face a permanent transformation of 200 hectares of agricultural land into an industrial tech park. This could lead to heightened concerns regarding localized noise pollution from cooling systems, increased heavy construction traffic over extended periods, and diminished access to traditional open green space. Conversely, if campaigners succeed in securing a fresh 12-week public consultation or forcing a planning review, it could set a procedural precedent for communities across the UK seeking greater democratic control over major infrastructure projects.
Impact on the Technology Sector and Infrastructure Developers
A final approval of the 600MW campus would establish one of Europe’s largest consolidated data processing hubs, significantly increasing the UK’s server capacity and digital infrastructure supply. However, prolonged resistance from local campaign groups and coordinated pan-European action networks like StopDirtyDataCentres.eu may lead to increased regulatory scrutiny, longer planning lead times, and potential policy shifts regarding power and water allocation for future data center applications across Europe.
Impact on Havering Council and the Regional Economy
For Havering Council, granting the LDO could deliver significant economic returns, generating substantial business rates, creating technical jobs, and funding local infrastructure through associated developer contributions, including the proposed district heating network and public ecology park. However, navigating the balance between economic development and community opposition presents political risks for council leadership, particularly regarding environmental commitments and the protection of local Green Belt designations.
