The proposed scope is divided into five areas: HV design and build; HV fault and protection studies; HV maintenance and inspection; ACB replacement and associated works; and ACB maintenance and inspection. This is electrical engineering, installation, testing and maintenance work for a water utility, with delivery coverage across the United Kingdom. The procurement is classified mainly as works, with additional services, and includes circuit breakers, switchgear, high-voltage installations, electricity distribution equipment, electrical power systems design and engineering studies. The process is at preliminary market engagement and planning stage. Yorkshire Water expects to use a framework agreement under the utilities regime, with a potential future tender rather than a current competition. The estimated gross value is £14,250,000, including VAT, in GBP. The proposed contract period for the structured lot runs from 1 February 2027 to 31 January 2031, with renewal potentially extending the maximum period to 31 January 2036. The buyer expected the next notice on 4 September 2026. Supplier engagement was planned through a voluntary, non-binding expression of interest, asking companies to identify relevant lots and provide basic capability information; this does not constitute a tender submission or commit Yorkshire Water to proceed or award a contract. This preparatory engagement is suited to specialist electrical contractors, engineering consultancies and maintenance providers able to deliver one or more of the five proposed work areas. Relevant strengths include high-voltage design and build, electrical power-system engineering, fault and protection studies, switchgear and circuit-breaker replacement, planned maintenance, inspection, testing and repair. Yorkshire Water is looking for suppliers to demonstrate relevant experience, technical capability, accreditations and geographic coverage. Businesses with established teams for utility, industrial or electrical distribution environments should assess which proposed lots match their services and prepare concise evidence of comparable work, qualifications, accreditations and delivery reach. The framework may suit firms able to support work across the UK and combine specialist engineering with reliable field maintenance capacity. ## Notice Yorkshire Water is conducting preliminary market engagement in relation to CM3576, covering specialist high-voltage (HV) electrical design, fault and protection studies, design and build, maintenance and inspection, together with air circuit breaker (ACB) replacement and maintenance services. For this engagement, the potential scope is presented across five lots: - Lot 1: HV design and build works - Lot 2: HV fault and protection studies - Lot 3: HV maintenance and inspection - Lot 4: ACB replacement and associated works - Lot 5: ACB maintenance and inspection Suppliers with relevant capability and experience in one or more lots are invited to express an interest in participating in a potential future tender. Interested suppliers will be asked to identify the lot(s) they could deliver and provide brief details of their relevant experience, accreditations, technical capability and geographic coverage. This notice is for market engagement only. It is voluntary and non-binding, does not constitute a call for competition, and does not commit Yorkshire Water to procure or award a contract. ### Planning Information Suppliers interested in participating in one or more of the proposed lots are invited to complete the online expression-of-interest form: https://forms.cloud.microsoft/e/2hgU7ZFN90 The form requests basic company and contact details, the lot(s) of interest, and a brief overview of the supplier's relevant services, experience, accreditations and delivery capability. Participation is voluntary and non-binding. Completing the form does not constitute a tender submission or create any commitment for Yorkshire Water to proceed. Further engagement, such as supplier calls or an RFI, may follow. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/081523-2026 | | Notice type | UK2 - Preliminary Market Engagement Notice | | Procurement type | Framework | | Procurement category | Works | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Planning | ## Dates | Field | Value | | --- | --- | | Publication date | 26 Aug 2026 | | Submission deadline | Not specified | | Future notice date | 4 Sep 2026 | | Award date | Not specified | | Contract period | 1 Feb 2027 - 31 Jan 2031 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £14,250,000 | | 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 | YORKSHIRE WATER SERVICES LIMITED | | Locality | BRADFORD | | Postcode area | Bradford | | Postcode | BD6 2SZ | | Country | England | | ITL 1 | TLE Yorkshire and The Humber | | ITL 2 | TLE4 West Yorkshire | | ITL 3 | TLE41 Bradford | | Local authority | Bradford | | Electoral ward | Royds | | Westminster constituency | Bradford South | | Delivery location | Not specified | ## CPV Codes ### Divisions - 31 - Electrical machinery, apparatus, equipment and consumables; lighting - 45 - Construction work - 50 - Repair and maintenance services - 51 - Installation services (except software) - 71 - Architectural, construction, engineering and inspection services ### Codes - 31212000 - Circuit breakers - 31214000 - Switchgear - 45315400 - High voltage installation work - 45315700 - Switching station installation work - 45317300 - Electrical installation work of electrical distribution apparatus - 50532000 - Repair and maintenance services of electrical machinery, apparatus and associated equipment - 51112000 - Installation services of electricity distribution and control equipment - 71323100 - Electrical power systems design services - 71335000 - Engineering studies - 71630000 - Technical inspection and testing services ## Release History - 26 Aug 2026 at 17:26 - PlanningUpdate - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/081523-2026 - 20 Aug 2026 at 15:20 - PlanningUpdate - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/079555-2026 - 20 Aug 2026 at 15:17 - Planning - UK2 - Preliminary Market Engagement Notice - https://www.find-tender.service.gov.uk/Notice/079550-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/081523-2026 26th August 2026 - Preliminary market engagement notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/079555-2026 20th August 2026 - Preliminary market engagement notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/079550-2026 20th August 2026 - Preliminary market engagement notice on Find a Tender ## Notice URLs - https://forms.cloud.microsoft/e/2hgU7ZFN90 - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
