BlackRock Inc. is planning to invest $678 million into the UK data center market with a new venture.

As reported by Bloomberg, US investment company BlackRock acquired a data center in west London that will seed a new venture with Digital Gravity Partners, dubbed Gravity Edge.

Details about the West London data center have not been provided.

Digital Gravity Partners will buy data centers with underutilized capacity, said BlackRock’s co-head of real estate, Thomas Mueller-Borja.

“We are trying to find existing assets that are underutilized but have power,” Mueller-Borja said. “We aren’t doing ground-up development for hyperscalers.”

Gravity Edge will target data centers with 5-20MW of capacity, according to a report from IPE Real Assets.

“We are always really focused on exit liquidity,” added Paul Tebbit, BlackRock’s other co-head of real estate. “One of the attractive things about this strategy, given the lot sizes we are creating, we can see real estate funds or infrastructure funds being the end buyer.”

BlackRock is providing an initial investment of £100m ($136m) from its £1.04 billion ($1.41bn) Europe Property Fund VI to modernize the first facility.

Thor Johnsen, managing partner at DGP, added: “We are thrilled to partner with BlackRock in building out this data center platform in the UK, which has the potential to scale across select sites in Europe. Gravity Edge currently delivers mission-critical data center services to a Tier 1 financial institution at an exceptionally well-run site.

“We plan to further modernize the facility, enhancing energy efficiency, enabling higher rack density, and unlocking additional sellable capacity. Our shared vision is to establish Gravity Edge as the default choice for customers requiring high-performance, mission-critical infrastructure, with operations designed for modern enterprise use cases in proximity to major urban hubs.”

BlackRock also owns European data center operator Mainova Webhouse. The investor also has a $30bn “AI Infrastructure Partnership” (AIP), which was founded in September last year with participation from Microsoft and Abu Dhabi-backed investment company MGX. In June 2025, the Sovereign wealth fund, the Kuwait Investment Authority, joined the AIP.

Digital Gravity Partners was founded in February 2024 and describes itself as a “specialized digital infrastructure investment advisor” with a focus on “mid-market assets, offering a value-add approach to building and growing leading, neutral and scalable platforms in four domains: data centers, subsea and terrestrial fiber networks, and wireless technologies.”
