How Telehouse is Investing £275m in Green London Data Centre

Telehouse International Corporation of Europe (Telehouse) has begun construction on its new £275m (US$370m) data centre, Telehouse West Two, at its London Docklands campus.

The project strengthens Telehouse’s 35-year legacy in the capital while setting a new standard for sustainable data centre development in the UK.

Set for completion in 2028, the facility will form part of Europe’s most connected data centre hub, supporting the increasing demand for energy-efficient, AI-ready digital infrastructure.

Construction is being led by Flynn Management & Contracting Ltd in partnership with Jones Engineering Group, specialists in mechanical, electrical and fire protection systems.

Built for sustainable AI and high-performance workloads

Telehouse West Two will be designed from the ground up to meet the growing power and efficiency needs of AI, high-performance computing and cloud workloads.

The nine-storey building will provide 32,000m² of space, including more than 11,000m² of white space across six levels, with a total power capacity of 33MW delivered through two new 132kV substations.

Each floor will deliver up to 4.4MW, supporting customers with dense, scalable compute environments. The data centre will combine air and liquid cooling systems to handle next-generation workloads while maintaining energy efficiency under demanding conditions.

Sustainability built into every layer

Sustainability is a defining feature of the Telehouse West Two project. The facility will be powered by 100% renewable energy and is being designed to achieve a BREEAM Excellent rating – a recognised benchmark for sustainable building performance.

Telehouse’s new site will feature advanced efficiency measures, including ultra-low power usage effectiveness (PUE) and water usage effectiveness (WUE) ratios.

The design also integrates heat recovery systems to reuse excess thermal energy and hydrotreated vegetable oil (HVO)-fuelled backup generators to reduce emissions.

“The new Telehouse West Two site marks another important step in our ongoing mission to deliver world-class, sustainable digital infrastructure,” says Kenkichi Honda, Managing Director of Telehouse Europe.

“This expansion will empower digital transformation for enterprise clients across multiple sectors, enabling them to benefit from emerging technologies which are shaping the future world, while supporting the uncompromising need for energy efficiency and carbon neutrality.”

Designed for resilience and efficiency

Telehouse West Two combines sustainable design with the resilience expected of mission-critical infrastructure. The facility will guarantee 99.999% uptime and incorporate multi-layered physical security systems, including 24/7 surveillance, on-site personnel and real-time monitoring.

By focusing on both environmental and operational efficiency, Telehouse is demonstrating how large-scale data centres can meet sustainability goals without compromising reliability or performance.

Supporting London’s green digital economy

Telehouse has been a cornerstone of London’s data economy for more than three decades. Its Docklands campus remains Europe’s most connected data centre location, home to hundreds of network carriers, cloud providers and internet exchanges.

The addition of Telehouse West Two strengthens the city’s position as a sustainable global technology hub, capable of supporting low-latency, AI-driven operations while aligning with the UK’s carbon reduction commitments.

The site will feature two meet-me rooms and four dedicated connectivity risers, ensuring highly efficient interconnection between customers and partners.

Collaboration driving green innovation

The project also underscores the importance of collaboration in achieving sustainability in large-scale infrastructure.

“We’re proud to have once again been appointed by Telehouse for a new building project,” says Kevin Flynn, CEO of Flynn. “Our team is ready to deliver on the company’s vision for a data centre that meets the ever-growing digital needs of companies, and it’s a great opportunity for us to further enhance our presence in the capital’s data centre market.”

Brendan McAtamney, Group Director of Jones Engineering Group, adds: “We’re delighted to work with Flynn on the engineering and installation of services to Telehouse West Two. This is a fantastic opportunity for us to work on a major data centre project in the heart of London, and we’re looking forward to getting started.”

Once complete, Telehouse West Two will stand as one of the UK’s most advanced sustainable data centres, combining energy efficiency, renewable power and circular design.

All in all, the project reflects the industry’s growing recognition that digital growth and environmental responsibility must go hand in hand – a balance that Telehouse aims to embed in every stage of its expansion.
