This project falls under the industry category of air pollution monitoring and technical inspection services and is scheduled during the planning stage. The procurement involves framework agreements for services related to emissions testing at nine Anaerobic Digestion sites located in the North West of England, with operations commencing on 1st July 2026 and potentially extending until 2036. Suppliers must conduct point source emissions testing on various stacks with detailed compliance to specific environmental regulations. The next key due date for market engagement is slated for 19th December 2025, with further notice anticipated by 28th February 2026. This tender offers a significant opportunity for growth within businesses specialising in air pollution monitoring, laboratory services, and technical inspection. Particularly well-suited to SMEs, the tender emphasises the importance of MCERTS certification or accreditation for monitoring equipment and personnel. With an approximate value of £1,000,000, the tender provides a robust platform for firms adept in emissions analysis, enhancing their portfolio through association with United Utilities, a key player in the utility sector. By meeting stringent environmental standards and providing flexible service delivery aligned with annual outage schedules, businesses can foster sustained growth and industry recognition. ## Notice United Utilities (UU) require point source emissions testing and analysis to be completed at 9 Anaerobic Digestion facilities, located in the North West of England. The testing is to be carried out annually with the ability to increase this frequency when enhanced monitoring is required on a site-by-site basis. Testing is required on Combined Heat and Power (CHP) engine exhaust stacks and Boiler exhaust stacks. Testing may be required on Flare Stacks, should a 10% annual 'run time' limit be exceeded. This would be treated as a reactive issue. Analysis and methods should fully comply with the requirements of the Environmental Permitting (England & Wales) Regulations 2016 implementing the Industrial Emissions Directive (IED). The Parameters and Monitoring Standard / Method include: * Oxides of Nitrogen (NO and NO2 expressed as NO2) - BS EN 14792 * Sulphur dioxide - BS EN 14791 or CEN TS 17021 or by calculation based on fuel sulphur * Carbon monoxide - BS EN 15058 * Total VOCs (including methane) - BS EN 12619 * Exhaust gas temperature - Traceable to National Standards * Exhaust gas pressure - Traceable to National Standards * Exhaust gas water vapour content - BS EN 14790-1 -Unless gas is dried before analysis of emissions. * Exhaust gas oxygen - BS EN 14789 * Exhaust gas flow - BS EN 16911-1 The contractor must have the ability to attend site again post survey within a reasonable timeframe to enable a re-test in the event of a result more than the stipulated emission limit. Operators undertaking the survey must have sufficient competence to undertake surveys safely on active gas and combustion assets. Operators must adhere to UU permitting and induction requirements. A UU representative must be available and attend the analysis. Monitoring equipment, techniques, personnel and organisations shall have either MCERTS certification or MCERTS accreditation (as appropriate). A report must be provided within a reasonable timeframe that includes methodology, data, results and conclusions. Conclusions shall clearly indicate if the results are compliant or non-compliant with the sites Environmental Permit emission limits. The accompanying report must stipulate a calculated 'methane slip' and total annual VOC emission. Contractors undertaking the survey must liaise with UU to arrange visits aligned to a pre agreed annual outage schedule. This needs to be flexible due to operational constraints. Contractors may be required to provide temporary access structures. ### Planning Information https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=100531&TID=105781&B= ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/079568-2025 | | Notice type | UK2 - Preliminary Market Engagement Notice | | Procurement type | Framework | | Procurement category | Services | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Planning | ## Dates | Field | Value | | --- | --- | | Publication date | 4 Dec 2025 | | Submission deadline | Not specified | | Future notice date | 28 Feb 2026 | | Award date | Not specified | | Contract period | 1 Jul 2026 - 30 Jun 2031 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £1,000,000 | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Planning | | Lots status | Planning | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | UNITED UTILITIES WATER LIMITED | | Locality | WARRINGTON | | Post town | Warrington | | Postcode | WA5 3LP | | Country | England | | ITL 1 | TLD North West (England) | | ITL 2 | TLD6 Cheshire | | ITL 3 | TLD61 Warrington | | Local authority | Warrington | | Electoral ward | Great Sankey North and Whittle Hall | | Westminster constituency | Warrington South | | Delivery location | TLD North West (England) | ## CPV Codes ### Divisions - 71 - Architectural, construction, engineering and inspection services - 90 - Sewage, refuse, cleaning and environmental services ### Codes - 71630000 - Technical inspection and testing services - 71900000 - Laboratory services - 90731000 - Services related to air pollution - 90731400 - Air pollution monitoring or measurement services ## Release History - 4 Dec 2025 at 09:18 - PlanningUpdate - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/079568-2025 - 2 Dec 2025 at 16:00 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/079047-2025 ## Documents - https://www.find-tender.service.gov.uk/Notice/079568-2025 4th December 2025 - Preliminary market engagement notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/079047-2025 2nd December 2025 - Preliminary market engagement notice on Find a Tender ## Notice URLs - https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=100531&TID=105781&B= - https://www.legislation.gov.uk/ukpga/2023/54/contents - https://www.unitedutilities.com ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
