## Summary

Northumbrian Water Limited (NWL) has awarded the contract for "MCERTS Inspection Services" to SIRIS Flow Inspections Ltd, following a competitive flexible procedure. The procurement belongs to the services category and the inspections are set to commence across 215 sites, ensuring regulatory compliance for flowmeters dispersed over regions including the North East Coast and up to the Scottish Borders. The contract award was made on 19th March 2026, with the official contract period beginning on 1st April 2026 and concluding on 31st March 2031. The standstill period ends on the 30th March 2026, marking the transition into the contract execution phase.

This tender provides significant growth opportunities for businesses specialising in flow-monitoring, testing, and compliance assessments within the utilities sector. The procurement method emphasises flexibility, with stages ranging from invitations to participate, dialogues, and best-final-offer submissions, allowing suppliers to engage dynamically throughout the process. Enterprises capable of delivering high-quality audits and MCERTS certifications would find themselves well-positioned to compete, contributing to the overarching compliance strategy of NWL. The involvement of SIRIS Flow Inspections Ltd, who are established as an SME, highlights the contract's suitability for small and medium-sized enterprises aiming to expand their footprint in utility service sectors.

## Notice

It is expected over AMP8 new sites and additional MCERTS instruments will be added to the schedule of inspecting.
