Data centre and homes plan compete for Charlton Riverside site

Data centre and homes plan compete for Charlton Riverside site

London is currently facing a significant challenge in balancing the growing need for digital infrastructure with its pressing housing and regeneration goals. The latest controversy has emerged in south-east London, where a substantial data centre development is proposed on land initially intended for housing. This development plan has sparked debate as local authorities and communities weigh the benefits of technological advancement against residential needs.

At Charlton Riverside, plans have been put forward for a 100,000 square metre data centre on industrial land, a project that Greenwich Council has already expressed strong opposition to, even before a formal planning application has been submitted. Proponents emphasize the vital role data centres play as foundational infrastructure supporting everyday digital activities, from banking and healthcare appointments to video streaming. Critics, however, voice concerns about energy consumption, water use, environmental impact, and whether these facilities should occupy sites reserved for new homes.

Mark Pestridge, managing director at Telehouse’s Tower Hamlets data centre, highlighted the rapid increase in demand for such facilities, driven by London’s importance as a global hub for finance and technology. He noted, “If you think about everything you do on a daily basis, whether you want to look at your bank account online, you want to look at your medical records or book a GP appointment, or stream a video, that will all run through a place like this.” The city’s concentration of businesses and financial services makes it particularly attractive to data centre operators who want proximity to their customers, as seen in the controversial facility approved for Brick Lane earlier this year.

Greenwich Council, represented by Tom Creswell, emphasizes their strategic vision for Charlton Riverside, which includes constructing around 8,000 new homes, enhancing public transport links, and creating 1,000 jobs. Creswell stressed that the council’s focus remains on the needs of local residents and meaningful community development. Those behind the data centre argue that regeneration in the area has progressed slowly and that their project would support housing delivery through improved infrastructure, while transforming an industrial estate into a more welcoming environment for both businesses and residents.

Local opposition remains strong. Some residents are worried about noise generated by the facility’s generators operating around the clock, as well as its high energy demands. One resident expressed concerns about overcrowding and the need for more homes instead of additional technology facilities. The government has responded to claims about data centres draining water resources by clarifying that these centres account for only 0.2% of non-household water use in England, with newer sites employing advanced cooling systems that minimize fresh water consumption.

Pestridge pointed out that Telehouse uses a closed water system, with overall water usage at national data centres being less than what is lost daily through leakage in water supply networks. He also noted that their electricity supply comes from offshore wind farms, and noise mitigation measures are in place to reduce disturbance to nearby communities. However, he acknowledged the industry’s shortfall in communicating its environmental impact accurately to the public. Meanwhile, water providers highlight the necessity of securing permission to invest in infrastructure needed to meet growing data centre demands.

This dispute over land use in Charlton is emblematic of a broader London-wide tension. As data centres become increasingly crucial to supporting digital services and artificial intelligence applications, competition for land intensifies in a city already grappling with housing shortages. Every proposed data centre triggers a complex conversation about priorities and community needs, reflecting the challenge of accommodating technological growth alongside vital urban development
