The National Audit Office highlighted that a review of the Weybridge site in 2021 found more than 1,000 examples of “single points of failure – where loss of the system or asset will cause major catastrophic disruption to operations”.29 The Department highlighted the potential failure of the Weybridge site incinerator, which is a critical piece of the site’s infrastructure, as a high-risk area. The Department told us that it expects to have two incinerators working independently by 2025 to increase resilience and to complete a new incinerator by 2030.30
