Retrofit Accelerator Showcase
The Building Centre, London
25 June 2026 17:00 - 25 June 2026 22:00
Where Retrofit
Meets Reality
The UK's retrofit challenge is vast. The solutions are emerging. This is where they meet.
Join us on the evening of 25th June at the Building Centre, London, for an exclusive showcase celebrating the innovators, industry partners and changemakers driving retrofit forward. This is not a conference. It is a curated evening of honest conversations, live demonstrations and genuine connection — designed for people who are serious about making retrofit work at scale.
You will have the opportunity to visit each company's dedicated stand, explore their technologies up close and speak directly with the innovators behind them. Later in the evening, they will join our industry partners — West Midlands Combined Authority, WPS and EDF Energy — for focused panel discussions offering an unfiltered look at what innovation in this space really looks like today.

Event Schedule
Retrofit Accelerator programme
The programme brings together innovative SMEs and leading industry partners to co-develop and trial solutions addressing key retrofit challenges across the built environment. Over several months, companies have worked closely with partners to refine their propositions, align them to real-world needs, and design practical, deployable trials.
The showcase event marks the culmination of this journey — highlighting the progress made, the partnerships formed, and the potential for these solutions to scale and deliver impact.
