ENVIRONMENT AGENCY · Transparency notice on Find a Tender

Tender information last checkedLast checked 30 Sept 2026, 02:07.

Opportunity overview

The Incident Management Forecasting System (IMFS) is the Environment Agency’s primary flood forecasting system and uses Deltares owned Delft-FEWS software as a platform to run models for flood forecasting, groundwater modelling, bathing water quality forecasting, and other services. The National Groundwater Modelling Service (NGMS) also uses Delft-FEWS software. The purpose of this Transparency Notice is to announce the Environment Agency's intention to enter into a contract for software support and maintenance (and the provision of new software enhancements and improvements) with Stichting Deltares for 5 years with the option to extend by a further 3 years and a further 2 years (i.e. 5+3+2) at a total maximum cost of £14.9m (net of VAT).

Published risks
The Environment Agency currently envisages that the following risks could jeopardise the satisfactory performance of the contract: a) Emerging cyber security threats and the impact this may have on the Environment Agency's need to make updates to software to address these threats; b) Changes in political direction and policy changes outside the Environment Agency's control that may drive diversified requirements for forecasting services; c) Climate change in the UK and the longer-term impact this may have on the provision of the services; and d) Technology obsolescence and new technologies, and the impact these may have on the provision of the services.

Why this procedure was chosen
Stichting Deltares are the sole owners and licensor of Delft-FEWS and there are no alternatives available to the Environment Agency without rewriting all forecasting models. It is the view of the Environment Agency that this contract is justifiable under Paragraph 5 in Schedule 5 of the Procurement Act 2023 to award the contract for the supply and support of the Delft-FEWS software because, as Stichting Deltares own the intellectual property for the software, and develop and support the specialist Delft-FEWS software, therefore no reasonable alternative exists, nor can another organisation supply and support the product. Additionally, it is the view of the Environment Agency that this contract is also justifiable under Paragraph 6 in Schedule 5 of the Procurement Act 2023 to award the contract for the supply and support of the Delft-FEWS software because, at this time, no alternative solution is available because any decision to deviate from Delft-FEWS would require a redevelopment of all Environment Agency models, therefore competition is absent for technical reasons.
