  • Lloyds has supported on a second successful Blue Bond for Tideway, to complete a £250 million 10-year issuance by Bazalgette Finance Plc.
  • The issuance – which attracted strong demand, with peak orders exceeding £875 million – reinforces Tideway's position as the only corporate sterling Blue Bond issuer to date. It also forms part of a resilient UK sustainable debt market, where so far in 2026, 10% of all bond issuance has chosen the green, social or sustainability use of proceeds format.
  • Lloyds has supported Tideway, a critical infrastructure asset, since project inception in 2015, providing capital markets advice and lending facilities across multiple development phases.
  • This latest transaction is another example of how Lloyds helps its clients access innovative financing solutions to support their long-term growth ambitions. 


Proceeds protect the River Thames

Blue Bonds are a specialised subset of green finance dedicated to water-related environmental outcomes. Proceeds from the issuance will be used to refinance existing debt raised to construct the 25-kilometre Thames Tideway Tunnel, designed to prevent sewage pollution from overflowing into the tidal river.

Since becoming operational in 2024, the infrastructure has diverted 22 million tonnes of sewage. This issuance provides long-term financing to maintain and operate the asset across its anticipated 120-year lifecycle, supporting the tunnel’s mission to clean up the Thames for future generations.

Supporting Tideway from the very start of the Thames Tideway Tunnel has been important to us, and as active bookrunner on its second Blue Bond underlines our commitment to this transformative project. As the only corporate sterling Blue Bond issuer, Tideway continues to set a benchmark for high-quality sustainable finance in UK infrastructure.

Hannah Simons Head of Sustainable Finance & Transition, Lloyds

The Thames Tideway Tunnel is already making a significant difference by preventing millions of tonnes of sewage from entering the river. This financing helps ensure we can maintain that progress and protect the Thames for generations to come.
