It’s a warm, sunny day on the Slough Trading Estate, where massive grey warehouses dominate the skyline. But inside one of these unassuming buildings, the future is unfolding.
At Equinix’s LD6 data center, Mike Oxborough, senior sales engineer, explains the high security measures required to enter, including biometric scans. Once through the airlock, known as the “man trap,” visitors are greeted by clean hallways lined with cages full of servers, their fans running overtime to cool the machines.
The facility is just one of six Equinix locations in the City, a vital hub for some of London’s financial institutions. Demand for data centres is soaring, driven by the explosive growth of artificial intelligence and cloud computing. With the UK government recently classifying data centres as “critical national infrastructure”, these massive facilities are more important than ever.
“The boom has already started,” says Haro Bosker, CEO of InLightn, a data center developer. “Over the past 25 years, IT has become more important, and companies are now investing more, even after economic cycles.”
This month, Amazon announced an £8bn investment in UK data centres, promising to create 14,000 new jobs. Meanwhile, Global Infrastructure Partners and Microsoft have launched a $30bn global fund to support AI-driven data centre projects. Investors, drawn by high capital requirements and high barriers to entry, are looking to capitalise on the rapidly expanding sector.
Data centres are no longer just urban phenomena. Regional hubs are gaining traction, with Newcastle emerging as a hotspot. Companies like Stellium are building data centres there, taking advantage of lower land and staff costs while staying connected by undersea fibre optic cables. AI could make these regional hubs even more viable, as they are less reliant on the low-latency requirements of traditional cloud computing.
Despite the optimism, challenges remain. Data centers are energy-intensive, with electricity needs expected to increase six-fold over the next decade. As the industry expands, balancing energy demands with sustainability goals is a critical issue.
The future is uncertain, but it’s clear that the UK is at the forefront of the data centre revolution. From Slough to Newcastle, these facilities are driving technological change, creating regional jobs and driving major infrastructure investment across the country.
