The contract, valued at £980,000, is set for an initial duration of four years, with potential extensions up to seven years, located in Dundee (region UKM71). This tender presents significant opportunities for businesses specialising in district heating systems, repair, and maintenance services of central heating infrastructure. Companies with expertise in emergency mechanical building services, civil engineering repairs, and the ability to meet the required quality and pricing criteria will find this tender particularly attractive. Engaging in this contract can bolster the successful bidder's portfolio, enhance market positioning in public sector contracts, and potentially secure long-term collaboration with a prestigious institution. The requirement for competent, certified suppliers underscores the need for businesses to demonstrate qualifications and prior experience in similar maintenance services. ## Notice The university's city campus underground district heating network (DHN) provides thermal energy to most of our teaching, research and student accommodation properties located on campus in addition to providing all the space heating and domestic hot water required by the NHS Dundee Dental Hospital. This thermal energy assists the university to comply with the H & S at Work Act 1974 and provides acceptable environmental comfort conditions for our staff, students, visitors, clinical patients and animals housed within our SoLS Resource Unit research facilities. We are looking to commence a new Framework contract with the existing supplier, or with a new supplier to replace the soon to expire Framework contract UoD-EFM-145-TC-2022. The thermal energy serving the DHN network is generated at source within our centralised main energy centre located at the northeastern corner of the campus. Most of the DHN schedule 40 and heavyweight mild carbon steel pipework below ground distribution system is located within purpose-built brick construction underground services ducts with load bearing slabs laid over beneath footpaths, road carriageways or soft landscaping. Over the last 20 years, extensions and additions to the DHN have generally been laid directly within soft or hard landscaping. The HTHW District Heating Pipework Lay Dates drawing, indicates that much of this network dates back to 1962 and is still in operation. Over the years and as the university has expanded and the thermal load increased, new excavations have been undertaken and new pipework laid below ground. The most recent extension of note to the DHN was in 2014. ### Lot Information Lot 1 Contract length: 4 years + 1 +1 +1. Extended maintenance and support options within the extension periods, required competent, certified supplier to service and maintain our system and provide emergency mechanical building services and civil engineering repairs on campus over the next seven years. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/049817-2026 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Tender, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 27 May 2026 | | Submission deadline | 29 Apr 2026 | | Future notice date | Not specified | | Award date | 27 May 2026 | | Contract period | Not specified | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £980,000 | | Lots value | £980,000 | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Unsuccessful | | Lots status | Cancelled | | Awards status | Unsuccessful | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | UNIVERSITY OF DUNDEE | | Locality | DUNDEE | | Post town | Dundee | | Postcode | DD1 4HN | | Country | Scotland | | ITL 1 | TLM Scotland | | ITL 2 | TLM0 Eastern Scotland | | ITL 3 | TLM03 Angus and Dundee City | | Local authority | Dundee City | | Electoral ward | West End | | Westminster constituency | Dundee Central | | Delivery location | TLM71 Angus and Dundee City | ## CPV Codes ### Divisions - 09 - Petroleum products, fuel, electricity and other sources of energy - 42 - Industrial machinery - 50 - Repair and maintenance services ### Codes - 09323000 - District heating - 42515000 - District heating boiler - 50720000 - Repair and maintenance services of central heating ## Release History - 27 May 2026 at 14:26 - Award - Award Notice - https://www.find-tender.service.gov.uk/Notice/049817-2026 - 30 Mar 2026 at 16:04 - Tender - Tender Notice - https://www.find-tender.service.gov.uk/Notice/029330-2026 ## Notice URLs - http://www.dundee.ac.uk - http://www.publiccontractsscotland.gov.uk - https://api.publiccontractsscotland.gov.uk/v1/Notice?id=ocds-r6ebe6-0000828006 - https://www.publiccontractsscotland.gov.uk/search/Search_AuthProfile.aspx?ID=AA00105 ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
