Buckinghamshire Council has approved Amazon Web Services' plans for a data center campus in Iver, Buckinghamshire, clearing the way for a 30,525 sqm (328,560 sq ft) facility that will replace 17 existing industrial and warehouse units.

The approval, first reported by the Bucks Free Press, includes 27 backup generators on site. Planning officers acknowledged a risk that the project could harm the surrounding landscape, but concluded that the benefits — including demand for data center capacity and potential employment opportunities — outweighed those costs.

The consent comes with financial obligations. Amazon will pay £600,382 toward projects to offset air pollution related to the development and will monitor emissions from its generators. The company will also invest £73,000 in improving public rights of way near the site. AWS still must submit additional information covering construction traffic, drainage, and water use before work proceeds.

Amazon Data Services filed the planning application in October 2025, three years after purchasing the site for £132.5 million ($165.6m) in an off-market deal in 2022.

Campus design and cooling

The filings describe the demolition of all existing structures on site and construction of a single two-story data center building, an MV building, a substation compound including two switchrooms and electrical infrastructure, and a generator yard housing the 27 backup generators. The generators will mostly run on hydrotreated vegetable oil (HVO), according to subsequent statements.

Cooling design relies on direct evaporative cooling fed by outside air for most of the year. During hotter days, the site will switch to adiabatic cooling, with rainwater as the primary supply and mains water as backup.

Location and AWS's UK footprint

Iver sits a few miles east of Slough, the largest data center hub in the greater London area and home to many large-scale developments. The approval extends AWS's presence in the corridor.

AWS currently operates one UK cloud region in the Bristol area — branded as "London" — which launched in 2016. A new availability zone was added in August 2026.

The company is linked to several other developments across the UK, including sites in Houghton Regis (Bedfordshire), Hayes (Middlesex), Didcot (Oxfordshire), Swindon (Wiltshire), and Bracknell (Berkshire).
