The procurement, using an open procedure, aims to ensure the continuation of essential audit services across various jurisdictions, including the British Oversea Territories, Channel Islands, Europe, Isle of Man, and the UK. The tender stage was initiated, with the contract starting on 2nd August 2021 and set to conclude on 31st July 2026. The total contract value has been adjusted to £39,009,747.80 to maintain service continuity without altering the core nature of the contracts. This tender presents substantial opportunities for businesses specialising in financial auditing and assurance, particularly those adept at managing government or large-scale audits. The open procurement method supports participation from small and medium-sized enterprises (SMEs), offering a significant revenue stream and potential for establishing long-term collaborations with a prominent UK governmental authority. Businesses that are already familiar with handling comprehensive fiscal audits and assurance services, particularly within the public sector, will find this opportunity advantageous for expanding their portfolio and enhancing their market presence. ## Notice Modification Notice Original description: BEIS and Transport are Department Group audits falling within the NAO's Infrastructure Group and so are aligned under the same business management processes. Several bodies within this Lot collect significant levels of income through levies or fees, and so an additional Trust Statement is prepared and audited that details income collected under this legislation. Description of the modifications The Financial Audit and Assurance Services contracts awarded under procurement reference GEN_20_22 have been modified to increase the overall contract value by PS9.6 million and extend the existing arrangements. The modification ensures continuity of audit and assurance services and supports the National Audit Office in meeting its statutory responsibilities. The nature, scope and objectives of the contracts remain unchanged. Description of the economic or technical reasons and the inconvenience or duplication of cost preventing a change of contractor: Additional audit and assurance services are required from the original contractors to ensure continuity of statutory audit delivery. Changing contractors at this stage would cause significant inconvenience, duplication of costs and disruption to audit planning, delivery and quality assurance. The modification does not alter the overall nature of the contracts and the increase remains below 50% of the original contract value. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/57f135ef-ca69-4a38-bc5e-adbb55f0685a | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 14 Jul 2026 | | Submission deadline | 22 Feb 2021 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 1 Aug 2021 - 31 Jul 2026 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £39,009,747 | | 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 | NATIONAL AUDIT OFFICE | | Locality | VICTORIA | | Post town | South West London | | Postcode | SW1W 9SP | | 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 | Pimlico North | | Westminster constituency | Cities of London and Westminster | | Delivery location | Not specified | ## CPV Codes ### Divisions - 79 - Business services: law, marketing, consulting, recruitment, printing and security ### Codes - 79200000 - Accounting, auditing and fiscal services ## Release History - 14 Jul 2026 at 15:00 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/57f135ef-ca69-4a38-bc5e-adbb55f0685a ## Documents - https://www.contractsfinder.service.gov.uk/Notice/57f135ef-ca69-4a38-bc5e-adbb55f0685a 14th July 2026 - Opportunity notice on Contracts Finder - https://www.delta-esourcing.com/delta/respondToList.html?noticeId=1049447830 Please follow this link to view the notice. ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
