The company expects the investment project to contribute 14 billion pounds to the country's gross domestic product by the end of 2028 and to support more than 14,000 jobs at British businesses.
The project represents a step-up in the pace of Amazon's investment in Britain. Since 2022 AWS has invested 3 billion pounds in facilities in London and Manchester.
"Our team that builds our data centres globally take into account multiple levers that they have to look at before they can decide where to put data centres ... from power to water to the local environment," Tanuja Randery, a managing director at AWS, told Reuters.
She singled out use of artificial intelligence as among the factors driving demand for cloud services.
The investment was welcomed by British finance minister Rachel Reeves, who has been courting foreign investors ahead of an investment summit on Oct. 14.
Britain's government said the data centres would be located to support demand in London and areas to the west, but that Amazon would not disclose the exact locations for security reasons.
"The government is also actively engaged in conversations with the company about investments in other parts of the UK," the finance ministry said.
