The UK’s Data Centre Services sector: A Brief Overview
In 2026, the UK’s data centre market is entering a period of structural expansion. The swift adoption of AI is driving demand for powerful computing infrastructure, while cloud migration, data-intensive applications and the continued growth of digital services are adding to the underlying requirement for capacity.
The implications of this extend beyond data centre operators and developers, as each new megawatt of capacity requires a complex ecosystem of specialist contractors and engineering businesses to design, build and maintain the facility. In July 2025, Peter Kyle, the UK secretary of state for technology, science and innovation stated that by 2030 the UK will need at least 6GW of AI-capable data centre capacity. For context, as of April 2026 the UK’s data centre capacity sat at 1.6GW. Given a large percentage of this capacity isn’t AI-capable, achieving 6GW of AI-capable data centre capacity by 2030 seems unlikely.
This creates a compelling outlook for the specialist construction services supply chain. Access to grid capacity, planning, skilled labour, specialist equipment and increasingly sophisticated cooling technology will determine how quickly new facilities can be delivered.
For investors and strategic acquirers, this combination of:
- Structural demand
- Technical complexity
- Recurring maintenance requirements
- A fragmented market with few high scale operators
is likely to make data centre construction services businesses increasingly attractive investment M&A targets.
The impact of AI on the UK’s data centre services sector
In the past, data centres have been an important component of the UK’s digital infrastructure. Now, AI is changing the scale and specification of facilities being developed. Traditional data centre demand was mostly driven by cloud computing, enterprise IT and digital services. In comparison, AI workloads are significantly more power-intensive, with high-performance GPUs generating considerably greater heat and requiring much higher rack densities. Jones Llang LaSalle estimates that AI could account for around 50% of all data centre workloads by 2030, while the growth of AI-focused “neocloud” providers is already accelerating demand for dedicated capacity.
For more context, neoclouds are specialised cloud providers that focus exclusively on GPU-as-a-service. Unlike the operational models that enterprises expect from Azure, AWS or Google Cloud, neocloud providers offer transparent, flat-rate pricing on a per-GPU hourly basis, without requiring long-term contracts. This means businesses are able to scale from a small number of GPUs to thousands without having to navigate complex procurement processes.
The consequence of fast adoption is not simply a requirement for more server space. New data centre facilities require greater electrical capacity, sophisticated cooling systems, resilient backup infrastructure and highperformance connectivity. CBRE Group, the world’s largest commercial real estate services and investment firm, expects that 185MW of new data centre supply will have been delivered in London by the end of 2026. 192MW was delivered in 2025 with the forecast take-up for 2026 standing at 211MW.
With over 200 data centres in London, the UK market is beginning to move beyond the capital’s established data centre clusters. As grid availability becomes increasingly important, developers are considering locations where power, land and planning regulations are more favourable. The result is a market in which the bottleneck is no longer just finding customers for capacity. It’s now finding power, people and contractors capable of delivering it.
Key Trends: Power Availability and Data Centre Opportunity
The growth of AI is changing the economics of data centre construction.
Power has become one of the industry’s most significant constraints. CBRE identifies grid capacity, connection lead times and competition for available supply as major factors determining where new UK capacity can be developed. These areas create opportunities further upstream in the supply chain, particularly for businesses involved in HV (High Voltage) infrastructure, grid connections, substations and electrical engineering.
Cooling is also becoming more technically demanding. Traditional air-based systems remain important, but higher-density AI workloads are accelerating the adoption of liquid cooling and other advanced thermal management solutions.
The shift is already visible in corporate activity. In 2025, global critical-infrastructure specialist Vertiv agreed to acquire PurgeRite, a specialist provider of mechanical flushing, purging and filtration services. The acquisition, valued at approximately USD 1 billion, highlights the growing importance of next-gen thermal management in high-density and AI-driven environments. […]
