LETI Investment for Impact #2

LETI ran a crowd funder campaign that closed in January 2022. We raised a brilliant £37,134 with186 supporters in 88 days! Please see link below to Crowdfunder page:


Every year or so we have a donations drive, the next one is expected in spring 2023. In the meantime if you wish to donate to LETI please contact and include 'Donate' in the subject line.


This financial support is incredibly important to us. It enables us to have more impact, pay for administrative support, travel further and plan more ambitiously for the future.

We are transparent about our income and spending, and will be publishing our annual CIC accounts and spending plans on this website in due course. 

What we've achieved


Initially LETI was managed purely by volunteers, giving their time both in working hours, but mostly in their own time. We have had no formal funding, organisation sponsorship or income from paid membership (aside from events, where event costs are covered by event sponsors). It is important to acknowledge that some organisations have given significant amount of ‘time and advice in kind’ over the last 3 years, notably Elementa, Levitt Bernstein and Etude. LETI was started using funding from Elementa’s impact fund and Elementa have continued to be amazing supporters, allowing space for LETI to grow and evolve and we are very grateful for this.

In 2020 LETI recently ran a crowd funding campaign to broaden our impact across the UK, and we raised nearly £12k.  

We are hugely grateful to all the supporters who donated this money; it has helped support LETI to have a huge impact over the last 18 months, despite the pandemic, in the following ways:

  • Hydrogen: a decarbonisation route for heat in buildings?

  • Embodied Carbon Target Alignment, and one pagers

  • Client Guide for Net Zero Carbon Buildings

  • LETI Climate Emergency Retrofit Guide

Consultation responses
  • MHCLG Future Building Standard 

  • Hydrogen one pending​

Ongoing Work
  • Supported a further six workstreams

  • Employed communication support, who is now providing 1.5 days a week of invaluable support with planning events, communications and keeping LETI organised.

Our commitment

As it is fundamental we remain independent, we think that crowdfunding is the best approach as it enables both organisations and individuals to contribute. This philosophy will allow us to remain independent of any vested interest and we will continue to be dedicated to the acceleration of the industry’s efforts towards achieving Net Zero Carbon buildings as soon as possible. We believe that LETI’s collective voice has had a significant impact over the last 5 years and we would like this to continue. If you agree, please support us.
