The Primary Markets Are Maturing, Secondary Cities Are Rising
For years, the FLAP-D markets of Frankfurt, London, Amsterdam, Paris, and Dublin have dominated European data center development. These cities have built deep ecosystems of connectivity, talent, and operator presence that made them the natural first choice for any major infrastructure investment. However, the continued expansion of these primary hubs is expected to slow during the forecast period due to mounting power and land scarcity challenges.
As a direct result, secondary markets including Milan, Madrid, Brussels, Lisbon, Athens, Oslo, Stockholm, Copenhagen, Helsinki, Warsaw, and Vienna are establishing themselves as compelling alternative destinations. Operators are increasingly directing capital toward these markets where land is more available, power infrastructure has room to grow, and local governments are actively courting data center investment through dedicated economic zones and incentive programs.
The UK and Germany Lead Investment by Volume
In 2025, the United Kingdom accounted for the highest data center investment share in Europe at approximately 27%, followed by Germany at around 12%. The UK's continued dominance reflects London's deep-rooted position as a global financial and technology hub, supported by strong connectivity infrastructure and a mature operator ecosystem.
Germany's significant share is reinforced by major hyperscale commitments. In November 2025, Google announced plans to invest more than USD 6.38 billion to enhance its data center capabilities in Germany, including a new facility in Dietzenbach and an expansion of its existing operation in Hanau. Investments of this scale from individual hyperscalers illustrate how concentrated capital flows can quickly reshape the competitive landscape within a single national market.
Liquid Cooling Is Becoming Essential Infrastructure
The rapid growth of AI and high-performance computing workloads across Europe is fundamentally changing how data centers manage heat. Traditional air-based cooling systems simply cannot dissipate the volume of heat generated by dense GPU clusters running AI workloads efficiently. As a result, liquid cooling technologies accounted for approximately 30.38% of cooling technique investments in 2025, with that share expected to rise to around 36.52% by 2031.
UK-based Spode Works Regeneration Ltd announced plans in October 2025 to build a new data center in Staffordshire featuring direct-to-chip liquid cooling, reflecting how even newer entrants to the market are designing facilities around advanced thermal management from the outset rather than retrofitting older infrastructure. As AI adoption deepens further, the demand for both direct-to-chip and immersion cooling techniques is expected to accelerate significantly across the continent.
District Heating Is Turning Server Heat Into Public Good
One of the most distinctive sustainability innovations in the European data center market is the rise of district heating integration. Rather than expelling waste heat into the atmosphere, an increasing number of operators are redirecting it to meet the heating needs of nearby residential, commercial, and public facilities.
In February 2026, nLighten announced plans to supply waste heat from its Stuttgart, Germany facility to the regional district heating system, expected to provide approximately 1.8 MW of heat that will support the city's broader decarbonization efforts. This kind of circular infrastructure model is gaining traction across multiple European countries as operators look for ways to demonstrate tangible community and environmental benefit alongside their core digital infrastructure operations.
Cloud Computing Growth Continues to Accelerate
Strict data regulation policies, accelerating digitalization, and the continued rollout of 5G connectivity are all driving sustained growth in cloud computing adoption across Europe. In November 2025, OVHcloud launched a third cloud region in Berlin, enhancing resilience and security for European digital infrastructure while also introducing an AI inference platform developed in partnership with SambaNova Systems.
As more European enterprises across banking, healthcare, government, and education shift their operations to cloud platforms, the underlying demand for low-latency, scalable data center infrastructure to support these services continues to climb in parallel.
Submarine Cable Investment Is Strengthening Connectivity
Europe's position as a global digital hub depends heavily on the strength of its connectivity infrastructure, and submarine cable investment is accelerating to keep pace with rising data demands. Amazon Web Services plans to establish a new cable landing station in Cork, Ireland, in January 2026, located at Tullyneasky West and including a substation, switch room building, and supporting infrastructure including generators and fuel tanks.
This kind of connectivity investment is essential for supporting the growing volume of AI, cloud, and digital transformation traffic flowing across European borders and beyond. As demand for high-speed, low-latency connections continues to rise, submarine cable development will remain a critical enabler of broader data center market growth.
Government Support Is Becoming More Coordinated
European governments increasingly recognize data centers as strategic infrastructure essential to digital economic competitiveness, and policy support is becoming more structured as a result. In January 2026, UK lawmakers formed the Data Centres All-Party Parliamentary Group, an initiative focused on improving understanding of the industry's economic contribution, strengthening digital infrastructure resilience, and supporting the UK's net-zero commitments.
Across the continent, governments are launching renewable energy partnerships, tax incentive programs, and dedicated economic zones designed to attract both domestic and international data center investment. This trend toward more sophisticated and coordinated government engagement is expected to continue strengthening throughout the forecast period.
Western Europe Dominates, But Growth Is Spreading
Western Europe accounted for approximately 76.75% of total European data center investment in 2025, anchored by the deep digital infrastructure hubs found in the FLAP-D markets. The Nordic region and Central and Eastern Europe represent the next largest contributors, with both regions showing strong upward momentum.
The Nordic countries, particularly Sweden, Norway, and Finland, are positioning themselves as premier destinations for AI-optimized data center development. Their combination of abundant renewable energy resources and naturally cool climates enables operators to reduce both their carbon footprint and operational costs simultaneously. Sweden held the largest hyperscale data center power capacity in Europe in 2025, supported by the government's Digitalization Strategy 2025 to 2030, launched in May 2025 to enhance the country's broader digital infrastructure ambitions.
Electricity shortages in established markets including the UK, Germany, France, Ireland, and the Netherlands are accelerating the shift of investment toward emerging markets including Norway, Sweden, Spain, Italy, Finland, Poland, and Austria, where power availability and cost structures remain more favorable.
Country-Level Dynamics Reveal a Diverse Continent
Europe's data center market is far from uniform, with each country bringing distinct characteristics to the broader landscape. France has committed to reducing greenhouse gas emissions by 55% by 2030 and reaching carbon neutrality by 2050, pushing operators including nLighten, which signed a renewable energy supply agreement with Axpo in December 2025, to actively decarbonize their French operations.
Construction costs vary significantly across the continent. Switzerland ranks among the most expensive markets for data center construction, alongside Norway, Sweden, Finland, the UK, and Germany, while countries including France, Portugal, Spain, Italy, Poland, and Greece offer comparatively lower development costs. This cost differential is an important factor influencing where operators choose to locate new capacity, particularly for less latency-sensitive workloads.
Industry associations are playing an increasingly important coordinating role across multiple countries. The Danish Data Center Industry, the Dutch Data Center Association, and the Swiss Data Center Association each represent their respective national ecosystems, working closely with governments and regulators to support sustainable industry growth and policy alignment.
Italy's network of approximately eight Special Economic Zones, spanning regions including Abruzzo, Campania, Eastern and Western Sicily, and Sardinia, offers data center operators tax incentives alongside critical infrastructure access for power, water, and connectivity, helping the country attract investment that might otherwise flow exclusively to Western European hubs.
Colocation Operators Drive Most of the Capacity Growth
