Can London and Frankfurt Stay Competitive as Europe's Data Center Prices Split?

What You Pay for a Rack in London Isn't What You Pay for One in Warsaw — And the Gap Is Only Widening

Anyone buying for colocation capacity across Europe this year has run into the same problem: the map of "where to put your servers" has stopped looking anything like it did five years ago. Power availability, renewable energy access, and AI-readiness are pulling investment — and pricing — into corners of the continent that barely registered on operators' radar a decade ago.

How Big Is the Europe Data Center Colocation Market?

The short answer: big and growing faster than almost any other regional infrastructure category.

The Europe data center colocation market by investment is forecast to reach USD 46.51 billion by 2031, (which is probably €40.70 billion), growing at a CAGR of 25.94%. That isn't incremental growth — it's a structural shift driven by AI, machine learning, IoT, cloud adoption, 5G deployment, submarine cable investments, and sustainability initiatives all converging on the same limited pool of buildable, powerable land.

Colocation revenue specifically is projected to climb to USD 43.45 billion (€38.02 billion) by 2031, with electrical and mechanical infrastructure — not general shell construction — absorbing the fastest-growing share of that spend as operators race to support AI-ready rack densities.

Why Does the Same Rack Cost Different Money in Different Cities?

This is the question buyers are actually asking, even if the report doesn't hand out a single price-per-kW figure. What it does show is “why” the number moves so much depending on where you land:

1. Power cost and availability. Markets sitting on abundant renewable capacity — Nordic hydropower being the obvious example — carry a structural cooling and energy-cost advantage over power-constrained hubs like London and Frankfurt, where lengthening grid connection queues are pushing costs up just as fast as demand grows.
2. Cooling technology mix. Liquid cooling, direct-to-chip systems, and rear-door heat exchangers are becoming table stakes for AI and HPC workloads. Facilities that haven't retrofitted for high-density cooling are increasingly priced out of hyperscale and AI tenancy altogether, which pushes their older capacity toward steep discounts instead.
3. Connectivity and land scarcity. In dense hubs like London and Amsterdam, submarine cable landings and internet exchange proximity command a premium that secondary Central & Eastern European and Nordic markets simply don't carry yet — but that gap is what's making those secondary markets attractive on cost.

Bottom line: there's no single figure for "what colocation costs in Europe." It's a spread that widens the further you get from London and Frankfurt, and narrows as renewable-powered secondary markets scale up their own connectivity.

Where Is Investment Actually Landing Across Europe?

Looking past headline market size, each region is optimizing for something different:

1. United Kingdom — Europe's largest colocation market, growing at a CAGR of 28.84%, anchored by London's financial services demand and dense hyperscale cloud availability zones. QTS Data Centers' Project Wind campus, a roughly USD 13.2 billion investment (probably €11.55 billion), shows the scale of capital still committing to the UK despite rising costs.
2. Germany — Frankfurt's position as a major internet exchange keeps it among Europe's largest markets, backed by strong enterprise digitalization and growing AI infrastructure builds, including Data Center Partners' 17 MW AI-ready facility in Munich.
3. Spain and Italy — Madrid and Milan are strengthening as Southern European digital hubs, supported by submarine cable landings and accelerating enterprise cloud migration.
4. The Nordics — the fastest-growing region in the entire European colocation market, with Finland projected to post the highest growth rate of any country as operators lean on renewable hydropower and natural free-cooling climates to build AI-ready campuses at a lower operating-cost base than Western Europe.
5. Central & Eastern Europe — Poland is emerging as the leading investment destination in the region, with Austria and Czechia gaining traction as operators diversify away from the traditional FLAP-D markets in search of cheaper land and power.

Key Insight: the fastest-growing markets aren't the biggest ones. Finland, Poland, and the wider Nordic and CEE region are winning new investment precisely because they're cheaper to build and run in than London or Frankfurt — which is exactly the dynamic reshaping where "local pricing" looks most competitive.

What Does This Mean for Colocation Buyers?

For enterprises evaluating providers, the calculus has shifted from "which city has the most capacity" to "which city has the power, cooling, and connectivity to support what I actually need to run, at a cost I can defend." Retail colocation continues to serve financial institutions, healthcare organizations, and government agencies seeking carrier-neutral, compliant environments, while wholesale colocation is gaining ground as cloud operators offload growing workloads onto third-party campuses.

Operators including Equinix, Digital Realty, NTT DATA, Vantage Data Centers, Data4, AtlasEdge, and Nordic-focused players like atNorth and Green Mountain are all competing on the same levers now: renewable sourcing, liquid cooling readiness, and expansion into secondary markets where power is easier — and cheaper — to secure.

Conclusion: Location Is the New Price Tag

Whether measured in its USD ($) or in Euros (€), its role in powering everything from London trading floors to Finnish AI campuses, the Europe data center colocation market has become as much a geography story as an infrastructure one. The next few years won't be won by whoever has the most square footage — they'll be won by whoever secured power and cooling capacity early enough to hold a competitive price while everyone else waits in a grid connection queue.
