Datacentres in Slough: What They're Doing to Our Beloved Places 2026

Datacentres in Slough are transforming the landscape and raising urgent questions about their environmental toll. Amid headlines about droughts and wildfires, the sprawling data hubs on Slough Trading Estate symbolize the hidden costs of our digital age, from massive electricity consumption to water-hungry cooling systems.

The Rise of Datacentres in Slough

Once known for The Office and light industry, Slough now hosts vast, windowless structures that house thousands of servers. These facilities power everything from cloud storage to artificial intelligence, but their physical footprint is reshaping the town.

Equinix, a California-based company, operates one of the largest sites here. With over 100 cars in its lots and a constant low hum, it stands in stark contrast to neighboring businesses like Mr Clutch and Angling Direct. The juxtaposition is jarring—old-school commerce meets futuristic infrastructure.

Environmental Costs: Heat and Water

Datacentres require enormous amounts of electricity, often generated by fossil fuels, making them major contributors to carbon emissions. Additionally, their servers generate intense heat, necessitating cooling systems that consume millions of gallons of water annually.

In Slough, Thames Water employees across the street acknowledge the irony. One worker noted, "There’s loads of AI bits in there... all the water they use. It’s ridiculous." This sentiment echoes broader concerns about resource scarcity in a warming world.

Comparing Datacentre Impacts

Key Takeaways for Communities

• Datacentres bring few local jobs despite their size—automation and remote monitoring dominate.
• Water usage can strain local supplies, especially during droughts.
• Energy demands often conflict with net-zero targets.
• Communities need stronger regulations and transparency from tech companies.

What Can Be Done?

Local governments and citizens are pushing for better planning. Some suggest requiring datacentres to use renewable energy and recycled water. Others advocate for placing them in cooler climates or using innovative cooling technologies like liquid immersion.

Tech giants must also invest in efficiency. For example, AI workloads can be optimized to reduce processing power. Yet, as AI grows, so will the pressure on places like Slough—unless we act decisively.
