This procurement, classified under the Accounting, auditing, and fiscal services (CPV code: 79200000), involves a contract modification that extends the existing arrangements and increases the contract value by £9.6 million. The services are to be delivered across the British Oversea Territories, Channel Islands, Europe, Isle of Man, the Rest of the World, and the United Kingdom. The procurement is in the Tender stage and was published on 14th July 2026. The contract, initially commencing on 2nd August 2021, is extended through to 31st July 2026, utilising an open procedure procurement method. This tender presents opportunities for businesses specialising in financial auditing and assurance services to engage with a high-profile public sector entity. The continuity of audit delivery is paramount, and businesses with prior experience in similar services can leverage this chance to expand their portfolios. SMEs are deemed suitable for this opportunity, which suggests a competitive yet accessible market for small to medium-sized enterprises. The contract's continuity and its significant value make it an attractive prospect for businesses looking to establish or expand their public sector client base in the auditing industry. ## Notice Modification Notice Original description: These bodies are responsible for the representation of devolved affairs in HM Government, facilitating the smooth operation of devolution, liaising between the UK Government and these governments and the administering of certain reserved matters of government relating to Scotland, Wales and Northern Ireland. The National Lottery Community Fund provides grant support to community projects across the entire UK. 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/ec147078-89e6-4b31-9519-9b59f60f8943 | | 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 14:40 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/ec147078-89e6-4b31-9519-9b59f60f8943 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/ec147078-89e6-4b31-9519-9b59f60f8943 14th July 2026 - Opportunity notice on Contracts Finder - https://www.delta-esourcing.com/delta/respondToList.html?noticeId=1049451115 Please follow this link to view the notice. ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
