Framework: winning a place puts you on an approved list for future work. It's the entry ticket, not guaranteed work.
In plain English
Yorkshire Water wants a specialist contractor (or contractors) to carry out planned and reactive maintenance, emergency response and minor capital works on its ozone water-treatment plant equipment across Yorkshire, covering mechanical, electrical, instrumentation and control systems, from 1 April 2027 to 31 March 2030. This is a competitive flexible procedure to set up a framework of approved suppliers, so winning a place is an entry ticket to future call-off work rather than guaranteed work itself.
Good fit for: Specialist mechanical, electrical and instrumentation contractors experienced in ozone or water-treatment plant maintenance.
- Must have relevant experience and capability in this specialist field
Suppliers with relevant experience and capability are invited to express interest and participate in the CoP.
- Major design-and-build capital works are excluded and reserved for Tier 1 suppliers
Major design-and-build capital schemes are excluded from the framework and will be delivered through Yorkshire Water's Tier 1 suppliers.

What the buyer says
Yorkshire Water is conducting a Tender Notice to inform the development of a procurement strategy for specialist ozone maintenance and minor capital works across its ozone process-plant estate. The proposed framework will support end-to-end planned and reactive maintenance, technical support, emergency response and minor capital works associated with ozone-generation systems and related assets. This will include asset inspections, condition and performance assessments, fault diagnosis, breakdown repair, critical-spares management, obsolescence management, equipment replacement, refurbishment, upgrades and remediation. The scope may also include mechanical, electrical, instrumentation, control and automation works, testing, commissioning, performance validation, warranty support and the provision of maintenance documentation, asset data and operating guidance. Major design-and-build capital schemes are excluded from the framework and will be delivered through Yorkshire Water's Tier 1 suppliers. Suppliers with relevant experience and capability are invited to express interest and participate in the CoP.
