Summary of the contracting process

Yorkshire Water Services Limited procured specialist process ventilation and odour-control capability for its operational clean water and wastewater sites across the United Kingdom. The requirement covers site surveys, investigations, design and engineering of new, replacement or upgraded ventilation systems; supply and installation of ventilation and odour-control equipment; refurbishment of existing assets; and associated mechanical, electrical and structural interfaces. It also includes testing, commissioning, performance verification, asset information, operating manuals and handover documentation. The work supports Yorkshire Water’s capital delivery programme and the safe operation of its assets, including compliance with health, safety and environmental obligations such as COSHH, DSEAR and Industrial Emissions Directive requirements. The procurement combines services, equipment supply, installation works and engineering design within an open framework arrangement.

The procurement is complete and has reached award stage following an open procedure for utilities. One supplier was selected: Greenacre Environmental Systems Limited, an SME, with an award value of £15,800,000 including gross value, dated 11 August 2026. The framework’s estimated value was £16,060,000 including gross value. The award covers the single lot and has a contract period from 1 September 2026 to 31 August 2030; the lot period was 31 August 2026 to 31 August 2030. Evaluation was split equally between capability and commercial factors, each weighted at 50%. The framework permits call-offs by mini-competition or direct award, with reopening during its term to allow additional suppliers to apply on substantially the same terms. A standstill period ends on 20 August 2026, with signature scheduled for 21 August 2026.

This award demonstrates sustained demand from Yorkshire Water for end-to-end process ventilation and odour-control delivery across clean water and wastewater operations. A credible future competitor would need to combine specialist ventilation design and engineering with equipment supply, installation, refurbishment and plant-upgrade capability. Practical strength in site surveys, investigation, testing, commissioning and performance verification would be important, alongside the ability to manage mechanical, electrical and structural interfaces. Suppliers should be able to produce reliable asset information, operating manuals and handover documentation, and demonstrate safe delivery in regulated utility environments. Competence in COSHH, DSEAR and Industrial Emissions Directive obligations would help establish credibility. The successful supplier’s SME status also indicates that the requirement can be addressed by a focused specialist business with sufficient delivery capacity and relevant operational experience.
