UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

Westminster City Council is exploring suppliers for Sustainable Drainage Systems (SuDS) monitoring and weather monitoring stations. The requirement is expected to cover the supply and operation of monitoring equipment, together with associated data management, visualisation, maintenance and reporting services. The purpose is to collect and manage information about drainage performance, surface water and weather conditions, supporting environmental monitoring and decision-making. The work is classified as environmental monitoring and consultancy services, including surface water pollution monitoring and control, drainage services, and weather stations (CPV 90733500). Delivery is intended across the United Kingdom. This is a service requirement rather than a construction project, although suppliers may need to support installed monitoring infrastructure and related field activities.

This procurement is at the planning stage and is currently a preliminary market engagement exercise, rather than an invitation to tender. The Council intends to use supplier responses to develop the future procurement activity and specification. Interested suppliers are expected to complete an online questionnaire by 24 September 2026 at 5:00pm through the Council’s e-sourcing portal. The Council has identified one lot, with an indicative contract period from 1 January 2027 to 31 December 2030. The estimated value and final procurement procedure have not been settled in this planning record. The requirement is below the relevant threshold. Suppliers should treat the engagement date as an opportunity to provide market information, not as a tender submission deadline.

The engagement is likely to suit specialist environmental monitoring providers, drainage and water-quality companies, weather-station operators, data platforms, environmental consultants and maintenance contractors. Suppliers with experience installing or managing sensors, collecting reliable environmental data, integrating multiple data sources, and presenting results through clear visualisation tools should be well placed to contribute. Relevant capability may include surface water monitoring, weather measurement, pollution or drainage control, data quality assurance, analytical reporting and planned or reactive maintenance. The requirement could also suit smaller businesses and voluntary, community or social enterprises, as the Council has marked the lot as suitable for both SMEs and VCSEs. Businesses able to combine field services with dependable digital data management may be particularly relevant when the future specification is developed.
