Unlocking climate solutions in London’s built environment

The Better Futures Retrofit Accelerator creates a pathway to growth and commercial success for a diverse range of climate startups who are ready to implement and scale up their solutions to the climate crisis across the built environment sector, with a particular focus on decarbonising buildings. It offers a gateway into the London retrofit market, with the aim of unlocking the barriers to market entry, setting the foundation for a successful commercial scale up and reducing London’s greenhouse gas emissions significantly. 

Here is a glimpse of the Challenge Identification Workshop with the first cohort.

Hear from our cohort participants about their challenges and inspiration to join the accelerator:

  1. Anzen's co-founder Preethi Jayakumar
  2. Building Atlas' co-founder Stephen Lorimer

Powered by Imperial College London, via Undaunted and Enterprise, the Better Futures Retrofit Accelerator is part of the Greater London Authority's Better Futures programme, co-funded by the UK government through the UK Shared Prosperity Fund. 

What to expect from the programme 

Climate innovation SMEs

The Better Futures Retrofit Accelerator is looking for high-potential innovative climate tech SMEs and businesses whose technologies can provide a significant impact in reducing greenhouse gas emissions within the built environment retrofit sector. Innovations in physical and digital technologies, but not limited to:

  • building materials
  • building systems
  • energy solutions
  • digital products
  • other advisory services


Eligibility for businesses to participate in the cohort:

  • London-based
  • classified as in the LCEGS (Low Carbon Environmental Goods and Services) sector
  • developing products or services suitable for the retrofit sector which have the potential to save significant green-house gas emissions
  • ready to implement and scale up their solutions

We encourage people from underserved communities to apply and recognise under-representation of women, minority ethnic groups, disabled persons, neurodivergent persons, and the LGBTQI+ community in our startup portfolios.

To bridge this gap, Undaunted encourages applications from people of all races, religions, national origins, genders, sexual orientations, gender identities, gender expressions, and ages, as well as veterans and individuals with disabilities.

Imperial College London and Grantham Institute – Climate Change and the Environment values equity, diversity, and inclusion to improve representation across all its programmes and partnerships.

Select participants from the cohort will get the opportunity to get access to:

  • R&D advice
  • internships
  • technical workspace
  • a network of key industry stakeholders
  • demonstration trials and deployment of low-carbon building innovations


Applications are now closed for the Better Futures Retrofit Accelerator. If you're an interested stakeholder - investor, climate tech business expert, consultant or local authority working on making a relevant impact in London's built environment, you could get a chance to meet exciting businesses and hear live pitches. Reach out to us at undaunted@imperial.ac.uk to learn how you can participate in creating a sustainable retrofit market for SMEs to scale up.

Stakeholders and partners

The cohort will be guided through their knowledge to unblock the implementation of climate change solutions in London’s built environment. We are also looking for visionary partners who are willing to use a building project as a frame for the actions of the cohort, and to demonstrate first-of-a-kind innovations.
