The contract, initially established under reference GEN_20_22, is actively being modified to ensure the continuity of services required by the Crown Estate. This extension involves an increase in the contract value by £9.6 million, without exceeding 50% of the original value, and is crucial for meeting the National Audit Office’s statutory obligations through continuous audit and assurance services. This procurement falls under the services category, specifically targeting accounting, auditing, and fiscal services within various regions, including the British Overseas Territories, Channel Islands, Europe, Isle of Man, and more globally, with key operations continuing until 31st July 2026. This procurement opportunity is well-suited for businesses specialising in accounting and auditing services, especially those with expertise in auditing complex valuations under IFRS 9. The modification notice highlights a need for businesses that can provide seamless services without disruption, making it particularly advantageous for well-established firms that are already integrated within larger auditing networks and familiar with international financial regulations. Given the scale and scope of the project, small and medium enterprises with relevant qualifications and a strategic approach to valuation in retail and environmental sectors could find significant opportunities for growth and visibility by collaborating with the Crown Estate through this contract. ## Notice Modification Notice Original description: The Crown Estate is one of our most high profile clients with a varied portfolio of investment and development of lands and holdings to generate revenue for HM Treasury. For British Film Institute (BFI), they carry out a diverse range of activities to meet its charitable objects. Expertise in valuation of investment property in the retail and environment sectors, and expertise in auditing complex valuations accounted for under IFRS 9. 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/06757f07-9871-4867-80d7-e7c4c7a8216c | | 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/06757f07-9871-4867-80d7-e7c4c7a8216c ## Documents - https://www.contractsfinder.service.gov.uk/Notice/06757f07-9871-4867-80d7-e7c4c7a8216c 14th July 2026 - Opportunity notice on Contracts Finder - https://www.delta-esourcing.com/delta/respondToList.html?noticeId=1049450225 Please follow this link to view the notice. ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
