Unity Trust Bank launches £100m Green Tariff to cut carbon

Written by Lori Campbell on 6th Nov 2025

Unity Trust Bank – a Good With Money ‘Good Egg’ company – has launched a £100 million Green Tariff lending facility to help organisations reduce their carbon footprint and invest in energy-efficient projects.

The new fund offers preferential loan terms for projects that cut emissions and improve building performance, including low carbon heating systems, better insulation, small-scale renewable energy installations and climate resilience measures.

Replacing the bank’s award-winning Retrofit Transition Initiative (RTI), which has already funded energy efficiency upgrades for more than 1,770 affordable homes across the UK, the Green Tariff is designed to make sustainable investment more affordable and accessible for a wider range of organisations.




Matt Conroy, Head of Impact Propositions at Unity Trust Bank, said: “With a government target for the UK to reach net zero by 2050 and the increased costs of energy, it’s important to find solutions to support our customers to move to a low carbon economy.

“As a social impact bank, we believe that finance has an important role to play in achieving a greener future. This new tariff is aimed at helping customers to significantly reduce their carbon footprint, adopt more sustainable practices and protect the environment.

“The terms are designed to be clear, easily understood and to provide fair value to customers through transparent pricing and tangible cost benefits.”

The Green Tariff will be available to new and existing customers, including those who have already achieved high levels of energy efficiency.

Unity Trust Bank, which has set its own Net Zero target for 2045, is a signatory to the Fossil Fuel Non-Proliferation Treaty and excludes funding for high-carbon or high-polluting industries. All lending is assessed against one or more of the UN Sustainable Development Goals to ensure measurable positive impact on UK communities.

The launch builds on Unity’s long-standing commitment to sustainable finance. The bank received the King’s Award for Enterprise for Sustainable Development in 2024, recognising four decades of delivering positive impact.

By extending its support to more sectors and projects, Unity Trust Bank’s new £100 million Green Tariff aims to accelerate the UK’s transition to a low-carbon economy – one building at a time.
