Home Office Cloud Renewal Signals Deepening AWS Reliance

The UK Home Office is moving toward a public cloud hosting renewal that could net Amazon Web Services (AWS) more than £1 billion including VAT, according to reporting from The Register. A planning notice published October 30 estimates the contract value at £881,621,007, nearly double the approximately £450 million AWS secured for the existing contract in 2023.

If awarded, the contract is slated to run from December 2027 to December 2029, with a potential extension through December 2031. This procurement occurs as the UK government grapples with digital sovereignty. The Register reports that a 2024 Cabinet Office internal document admitted that vendor lock-in and risk concentration have inhibited the government's negotiating power, noting that the dominance of AWS and Microsoft Azure is expected to persist.

Data from the public sector intelligence platform BidSkim indicates AWS currently captures 75 percent of government cloud contract spending, totaling roughly £1.22 billion. In comparison, Microsoft Azure has secured £355 million, Google Cloud £47 million, and Oracle Cloud $15 million.

While the UK government recently pledged to direct more business toward small-to-medium sized enterprises (SMEs) and added local suppliers to the G-Cloud 15 framework in August, critics argue these efforts are insufficient. A supplier source cited by The Register claimed the administration fails to support UK providers and that professional services companies often advise officials to favor hyperscalers in exchange for roles as integration or migration partners. These developments follow warnings from the Open Rights Group regarding the UK's over-reliance on US firms for critical operations.
