LETI is a voluntary network of over 1,000 built environment professionals, working together to put the UK and the planet on the path to a zero carbon future. Our vision is to understand and clarify what this means in the built environment and develop the actions needed to meet the UK climate change targets.
Our volunteers are made up of developers, engineers, housing associations, architects, planners, academics, sustainability professionals, contractors and facilities managers, with support and input provided by local authorities and other organisations.
Originally the ‘London Energy Transformation Initiative’ (LETI) was established in 2017 to support the transition of the London’s built environment to meet Net Zero Carbon. Since then, LETI has formed as a Community Interest Company and altered our name to become the ‘Low Energy Transformation Initiative’, but predominantly we are known as LETI. This reflects our interest in all UK zero carbon policy and regulation.
LETI was established to support the transition of the UK’s built environment to Net Zero Carbon. We do this by:
→ engaging with stakeholders to develop a robust and rapid energy reduction approach, producing effective solutions to the energy trilemma of security, sustainability, and affordability
→ working with authorities to create practicable policy alterations to ensure the regulatory system is fit for purpose, placing verified performance at its core
→ encouraging and enabling collaboration between built environment professionals
→ providing technical guidance to support exemplar developments, enabling pioneers who aspire to go beyond the current regulatory frameworks
1. LETI is focusing on zero carbon as the outcome, but we recognise that reducing energy demand in the first instance is key to achieving a net zero carbon city.
2. The built environment focuses on buildings, but taking a holistic view incorporating the wider infrastructure, from local transport links to the national energy grids, is essential to reduce carbon emissions.

How to get involved
Volunteering for LETI offers an opportunity to learn and progress together, while providing professional development, research skills, and valuable networking. We encourage participants to share the LETI findings in their day jobs and with others- speeding up knowledge and understanding in the built environment industry as a whole.
