## Summary

UK Power Networks (Operations) Limited procured the removal of existing transformers and the delivery, lifting and positioning of three new high-value electrical transformers at Duke Street in Central London. The work involves mobile lifting frames and associated heavy-lift engineering in a constrained urban environment. The site includes a Grade 2 listed building, restricted access, live network risks and complex interfaces involving highways, permits, traffic management and confined spaces. The requirement covers the practical installation operation and coordination with The Wilson Transformer Company, the transformer manufacturer. This is a utility procurement focused on specialist transformer lifting and installation rather than general construction or routine equipment supply.

The procurement is complete and was awarded through a direct award under the utilities regime. UK Power Networks awarded the single requirement to J.B. Rawcliffe & Sons Limited on 15 June 2026. The awarded value is £670,000 excluding VAT and £804,000 including VAT. The contract period runs from 25 August 2026 to 24 August 2027, with signature scheduled for 14 August 2026. The buyer justified the direct award on technical grounds, citing the bespoke nature of the lifting and installation, the constrained Central London setting, live network risks and limited supplier capability. Evaluation was therefore based on the identified technical reasons for using a single supplier, including integrated heavy-lift engineering, relevant central London experience, regulatory compliance and UKPN authorisation.

This award demonstrates demand for suppliers able to plan and deliver complex transformer installation projects in central London and similarly constrained utility sites. A credible competitor would need integrated heavy-lift capability covering cranes, skidding and jacking, together with experienced lift engineering and site coordination. Demonstrable transformer installation experience in central London would be important, particularly where access, highways, permits, traffic management, confined spaces and live network interfaces must be managed together. Competence in LOLER and BS 7121, including lift design led by an appointed person, is central to the requirement. Suppliers would also need UK Power Networks authorisation or the ability to operate within its requirements, and effective coordination with The Wilson Transformer Company as original equipment manufacturer.

## Notice

This direct source is being proposed to send out a transparency notice reviewing whether UKPN could proceed to contractual and commercial negotiations with JB Rawcliffe & Sons for the removal of existing transformers and delivery, lifting and positions of new transformers at Duke Street.

### Procurement Information

The requirement involves bespoke lifting and installation of 3 high value electrical transformers in a constrained Central London environment with restricted access, live network risks, Grade 2 listed building and complex interfaces (highways, permits, traffic management, confined spaces). Market analysis confirms that only a limited number of suppliers possess: * Integrated heavy-lift engineering capability (crane + skidding + jacking) * Demonstrable experience delivering transformer installations in central London * Full compliance with LOLER and BS7121 including appointed person-led lift design * UKPN authorisation and interface with The Wilson Transformer Company (OEM of ordered Transformers).
