## Summary

The Environment Agency is procuring software programming and consultancy services to update its South East Soil Moisture Model. The work involves moving the existing model from Microsoft Excel and Microsoft Access to Python and associated managed databases. The supplier must also enable the model’s output data to be provided in gridded form, alongside the current areal-unit data. This is a technical data and software modernisation requirement for an environmental modelling application, rather than a general software development commission. Delivery is in South East England. The Environment Agency is the public sector buyer and central government authority responsible for the requirement. The opportunity may suit specialist software developers, data engineers, database consultants and environmental or hydrological modelling firms able to combine software migration with structured data production.

The procurement reached tender: the Environment Agency invited quotations through a below-threshold open competition. Suppliers were required to submit a quotation meeting the Request for Quotation requirements by email, with submissions due by 1pm on 17 September 2026; electronic submission was not allowed through the procurement system. Clarification questions were to be sent by email, with questions and responses potentially circulated to all tenderers unless commercially sensitive. There is one lot, with an estimated value of £50,000 excluding VAT and £60,000 including VAT. The contract period is 28 September 2026 to 24 March 2027. Tenders are evaluated on a combined score, weighted 50% technical and 50% commercial, with the highest-scoring tenderer winning.

This opportunity suits an SME or voluntary, community and social enterprise as well as larger specialist suppliers. Strong candidates will have practical experience migrating models and data from Microsoft Excel and Access into Python-based solutions and managed database environments. They should be able to understand, test and preserve an existing soil moisture model while improving how its outputs are structured and supplied. The requirement also favours capability in environmental, hydrological or geospatial data, particularly producing reliable gridded datasets as well as areal-unit results. Suppliers need the technical capacity to deliver a focused modernisation project and to demonstrate a sound technical approach in their quotation. Commercial competitiveness will matter equally with technical quality, so bidders should present a clear, deliverable solution and cost basis.
