Manchester’s digital economy is growing fast, but the servers, cooling systems, and power capacity that underpin it are becoming part of the city’s story.
A hidden test for Manchester’s tech ambitions
Manchester has become one of the UK’s most closely watched tech cities, with fast growth in AI, fintech, e-commerce and digital health. But behind the funding announcements sits a less glamorous question: where will its computing power live?
AI models, GPU clusters and high-performance systems need dense, reliable infrastructure. Much of the regional data centre stock was built for older enterprise workloads, not for the heat and power demands now arriving on the city’s doorstep.
The numbers point to rising demand
Government investment material describes Greater Manchester as a £5 billion tech ecosystem, with more than 10,000 digital and tech businesses, and around 250 AI companies.
In 2024, the UK government designated data centres as Critical National Infrastructure, recognising their role in keeping the economy, public services and digital systems running.
One provider expanding locally is Carbon-Z, a specialist in colocation in Manchester, with sites and network presence spanning Swindon, Hayes in West London and Manchester. Its infrastructure is built around immersion cooling, Direct-to-Chip technology, and renewable-powered operations for AI workloads, GPU clusters and enterprise compute.
Why is this no longer background plumbing
Manchester’s growth is not happening in one pocket of the city. MediaCity, the Oxford Road Corridor, Spinningfields, Manchester Science Park, and innovation districts have helped create a serious concentration of digital activity.
The issue is that compute demand has a physical footprint. Servers need power. Dense racks create heat. Cooling systems need efficiency. Local grid capacity matters. That makes data centre planning part of the same conversation as investment, skills and growth.
Manchester also has a 2038 carbon-neutral target, making old-style infrastructure expansion harder to defend if newer cooling methods can support more computing with less wasted energy.
The cooling challenge behind AI
AI hardware, especially GPU-based systems, can produce a large amount of heat in a small space. Traditional air cooling still has a place, but it can become inefficient when racks become very dense.
Immersion cooling places servers in a non-conductive liquid that removes heat more effectively than air. Direct-to-Chip cooling sends liquid directly to the hottest components inside a server, including CPUs and GPUs.
Both approaches move cooling closer to the heat source, allowing higher rack densities, better thermal control and more efficient use of space.
What local compute changes for businesses
For Manchester businesses, local high-density capacity can affect latency, resilience, data control and cost planning.
Some workloads will still suit public cloud. Others, particularly sustained AI training, high-performance computing or predictable enterprise workloads, may be better served through dedicated colocation. The question is not cloud versus data centre. It is which workload belongs where.
A city cannot build a serious AI economy on software talent alone. It also needs power, cooling, connectivity and secure places to host the machines doing the work.
The view from Carbon-Z
Jon Clark, Commercial and Operations Director at Carbon-Z, said Manchester’s compute demand has moved faster than many outside the infrastructure sector realise.
“Manchester is now a serious digital economy, particularly across AI, fintech and data-led businesses. What is changing is the type of infrastructure those companies need.
“Much of the local data centre stock was designed for traditional enterprise workloads. Supporting GPU-heavy environments is different because heat, density and power become commercial issues, not just technical ones.
“Immersion and Direct-to-Chip cooling allow more compute to be deployed in less space, with more controlled thermal performance. Sustainability is no longer optional. Investors, regulators and enterprise customers increasingly expect clear answers on power use, cooling efficiency, water use and carbon impact.”
What could change over the next two years?
The next 24 months are likely to bring closer scrutiny of high-density colocation capacity across Greater Manchester and the North West.
Local authorities and regulators are expected to pay more attention to data centre power use, water consumption and grid impact. The IEA says global data centre electricity demand could more than double by 2030, with AI as a major driver.
Expect closer links between operators, universities and digital businesses, where research and commercial workloads need secure, efficient and regionally available infrastructure.
The next layer of Manchester’s growth story
Manchester’s tech success has reached the point where the infrastructure beneath it deserves attention in its own right.
The city’s ambition around AI, digital investment and carbon reduction depends on getting the next generation of data centre capacity right. High-density, efficient and locally available compute is becoming part of the conditions for regional growth.
The next phase of Manchester’s tech story will not be written by software alone. It will be written by what is running underneath it.
