## Summary

Transport for London has awarded a contract to Walter Frank & Sons Limited for the maintenance of Fire Pressure Regulated Valves (PRVs) on the Elizabeth Line. This contract, valued at over £1.3 million, will span from April 2026 to April 2029, with potential extensions up to 2031. The procurement method employed was a competitive flexible procedure, concluded through a selective tender. The industry category is services, specifically focusing on repair and maintenance services with a special regime for utilities. Located in London, this contract has achieved legislative compliance under PA23 regulations. Engagement with stakeholders has been completed, ensuring commercial leverage and savings through the competitive tender process.

The tender represents significant opportunities for businesses specialising in fire-protection devices repair and maintenance to expand their reach into public infrastructure projects. Businesses with the capability to service and calibrate specialised safety equipment, particularly those providing off-site solutions compliant with OEM standards, would find this contract a lucrative opportunity. Small and medium-sized enterprises (SMEs) and suppliers with expertise in technical and commercial submissions are particularly well-suited to compete. Given the selective procurement process, it encourages market participation and aims at achieving the Most Advantageous Tender, promoting fairness and fostering growth for skilled service providers by enhancing technical and commercial value.

## Notice

There is a requirement to establish a new contract for the maintenance of the Pressure Regulating Valves (PRVs) that form part of the Elizabeth line fire suppression system. The current contract, awarded via Single Source to the manufacturer, Walter Frank, is due for re procurement. Moving to a competitive process aligns with TfL's procurement strategy by opening the requirement to market competition, supporting value for money, improved commercial leverage, and compliance with PA23 regulations. Maintenance of the PRVs is a highly specialised activity involving off site servicing, testing and recalibration, and the issuance of Certificates of Conformity. There are 1,584 PRVs in service, and maintenance is required on a 36-month cycle, based on Elizabeth line Asset Engineering guidance. TfL will undertake all removal and reinstallation; the service provider will be responsible solely for offsite works. Up to 40 PRVs may be processed weekly. A competitive flexible procedure will be undertaken via Find a Tender (FTS) to ensure full market participation - including the incumbent, who is not registered on RISQS. A prior market engagement notice generated six expressions of interest. These suppliers will progress through to the next stage and would be invited to tender has it is anticipated that not all suppliers would submit one. This contract will ensure continued regulatory compliance, operational reliability of safety critical assets, and alignment with wider strategies including asset management principles, TfL's vision and values, and the commitments of the Mayor's Transport Strategy. Significant savings and commercial improvements were anticipated through the introduction of competition and achieved. A preliminary market engagement notice (UK2) was issued via the Find a Tender Service (FTS). This resulted in six expressions of interest being received via email, in addition to a submission from the incumbent supplier, bringing the total number of responses to seven. Following this engagement, only two suppliers proceeded to submit a formal bid.
