United Utilities has gone out to tender with an AMP8 framework contract for centrifuge and associated maintenance services with an estimated total value of £12 million (inc VAT).

Current estimated start and end contract dates 6 April 2026 to 31 March 2029, with further possible extension options up to 31 March 2034.

United Utilities is looking to appoint a maximum of two suppliers to the framework.
