UK4 - Tender Notice
Summary of the contracting process

Trinity House is seeking an accredited certification body to provide auditing services for its ISO certification programme. The work is to support a new certification period covering ISO 9001, ISO 14001 and ISO 45001, together with SSiP, and includes migration to the 2026 standards. The supplier will carry out certification audits and associated surveillance audits every 12 months. The service is for Trinity House, with delivery across its locations in the United Kingdom. This is a single service requirement for integrated certification and surveillance auditing, rather than separate tenders for each standard.

The buyer invited offers through an open, below-threshold competition. The tender set a deadline of 28 October 2026 at 17:00 for submissions, with enquiries due by 23 October 2026 at 12:00. The contract period runs from 1 December 2026 to 30 November 2029. The estimated value is £60,000 excluding VAT (£72,000 including VAT). There is one lot. Evaluation allocates 30% to relevant experience, 20% to auditor competence, local coverage and continuity, and 10% to added value or innovation. Price accounts for 30%, including rates and the required cost schedule; acceptance of the buyer’s terms, or acceptability of proposed amendments, accounts for the remaining 10%.

This requirement is suited to certification bodies accredited to deliver audits against ISO 9001, ISO 14001 and ISO 45001, with the capability to cover SSiP and support migration to the 2026 standards. Bidders will need auditors able to conduct integrated audits, a pool of suitably competent personnel to maintain continuity, and auditors located near Trinity House’s sites. Experience working with organisations whose background and responsibilities are similar to Trinity House is a significant part of the assessment. Suppliers should be able to evidence successful delivery of any proposed added-value or innovative resources. The lot is identified as suitable for small and medium-sized businesses, so specialist audit firms may compete alongside larger providers if they can demonstrate the required coverage and service consistency.
