McLaren Construction and Phoenix ME Appointed on 140MW Corscale Data Centre Development in Buckinghamshire

Corscale has appointed McLaren Construction and Phoenix ME under a Pre-Construction Services Agreement (PCSA) to commence pre-development works on a major new 140MW data centre campus at Court Lane, Iver, Buckinghamshire.

The development represents a significant investment in UK digital infrastructure and will occupy a 14-acre site within West London’s established data centre corridor, strategically located adjacent to the M25 motorway.

Pre-development works are scheduled to commence on 1 July 2026, with practical completion targeted for Q4 2029.

Project Overview

The proposed campus will comprise:

• Two hyperscale data centre buildings

• A dedicated 140MVA electrical substation

• Associated infrastructure and external works

• Biodiversity enhancements

• Extensive remediation and enabling works

The development has been designed by Gensler, with a focus on integrating the scheme into the surrounding environment, including architectural considerations relating to a nearby Grade II listed farmhouse.

The site is currently occupied by a mix of industrial uses, including waste transfer operations, metal recycling facilities, concrete and aggregate storage, vehicle storage and industrial units.

Early works will focus on site clearance, remediation activities and the relocation of two 36-inch water mains in conjunction with Affinity Water.

Strategic Context

The Court Lane development is located within one of the UK’s most important data centre markets, serving the growing demand for cloud computing, AI infrastructure, digital services and hyperscale data storage.

At 140MW, the project represents a major addition to the UK’s data centre capacity and highlights continued investment into mission-critical infrastructure across the South East.

The appointment of McLaren Construction and Phoenix ME at this stage provides early visibility of a significant long-term project with a construction programme extending through to 2029.

ConstructNet Opportunity Analysis

With enabling works commencing in July 2026 and a multi-year delivery programme ahead, the scheme is expected to generate substantial supply chain opportunities across a wide range of specialist disciplines.

Potential opportunities may include:

• Demolition and site clearance

• Remediation works

• Groundworks and infrastructure

• Utility diversions

• Drainage installations

• Structural steel packages

• Cladding and façade systems

• Roofing works

• Mechanical installations

• Electrical infrastructure

• Data centre specialist systems

• Fire protection installations

• Security systems

• External works and landscaping

• Plant hire

• Waste management and recycling

• Building materials supply

• Logistics and haulage services

The relocation of major water infrastructure and delivery of remediation works are expected to form some of the earliest procurement activities as the project progresses through the pre-construction phase.

The involvement of McLaren Construction and Phoenix ME also provides valuable visibility for suppliers already active within the mission-critical and data centre sectors.
