This procurement, classified under air quality management (CPV code: 90731100), aims to provide additional nitrogen dioxide (NO2) monitoring data for inclusion in national UK compliance assessments. The network is currently operating at approximately 299 sites, focusing on areas where modelling has indicated exceedances of the annual mean NO2 limit value. The open procedure (above threshold) will accept submissions until 29 November 2024 at 12:00 PM, with the contract starting on 1 January 2025 and ending on 31 March 2030. The delivery addresses span across various locations, including British Overseas Territories, Channel Islands, Europe, Isle of Man, Rest of the World, and the United Kingdom. This tender represents a significant opportunity for businesses involved in environmental monitoring and air quality management, specifically those capable of providing NO2 monitoring solutions. Given the project’s scope and the extensive deployment of monitoring sites, companies with expertise in environmental technology and data analytics are well-suited to participate. Small and medium-sized enterprises (SMEs) are encouraged to apply, as the procurement process is designed to be inclusive, promoting business growth within this vital industry sector. This tender not only offers potential long-term collaboration with a key governmental department but also contributes to improving environmental quality and public health. ## Notice The procurement documents are available for unrestricted and full direct access, free of charge, at https://defra-family.force.com/s/Welcome Any questions, requests to participate or tender submissions must be submitted electronically via this portal. The UUNN was first established in January 2020 and has expanded since to respond to evidence needs and is currently operating at ~299 sites. The primary aim of the UUNN is the provision of additional NO2 monitoring data for inclusion within the national UK compliance assessment. Previously the national assessment of NO2 has comprised of a UK-wide automatic monitoring network; the Automatic Urban and Rural Network (AURN), and national scale modelling; the Pollution Climate Mapping (PCM) model. UUNN monitors were sited specifically to target areas where modelling had indicated an exceedance of the annual mean NO2 limit value, and where concentrations predicted by the PCM model and by local modelling completed by a relevant local authority were not in good agreeme ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/e1479039-f0da-46ad-bffc-2e3c59c7b304 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure (above threshold) | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 12 Feb 2025 | | Submission deadline | 29 Nov 2024 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 1 Jan 2025 - 31 Mar 2030 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £1 | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | DEFRA | | Locality | LONDON | | Post town | South West London | | Postcode | SW1P 4DF | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | Not specified | ## CPV Codes ### Divisions - 90 - Sewage, refuse, cleaning and environmental services ### Codes - 90731100 - Air quality management ## Release History - 12 Feb 2025 at 14:25 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/e1479039-f0da-46ad-bffc-2e3c59c7b304 - 5 Nov 2024 at 10:45 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/f0b2f2d6-73c1-4b56-8582-8a0b876cc2b5 - 24 Oct 2024 at 08:56 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/2aa50b22-e8be-465d-8492-93af6f63712b ## Documents - https://www.contractsfinder.service.gov.uk/Notice/e1479039-f0da-46ad-bffc-2e3c59c7b304 12th February 2025 - Opportunity notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/f0b2f2d6-73c1-4b56-8582-8a0b876cc2b5 5th November 2024 - Opportunity notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/2aa50b22-e8be-465d-8492-93af6f63712b 24th October 2024 - Opportunity notice on Contracts Finder ## Notice URLs - https://defra-family.force.com/s/Welcome ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
