Retrofit Success Stories: Unlocking shared solar power for flats in Lewisham

Introduction

This Retrofit Success Stories case study highlights how Allume supported Lewisham Borough Council in deploying its SolShare technology across flats as part of Wave 2.1 of the Government’s Social Housing Decarbonisation Fund (SHDF). To gain deeper insight into the motivations, experiences, and lessons learned from delivering Governmentfunded retrofit projects, we spoke with two Allume team members, Ramin and Jack, who shared their reflections on implementing SolShare within largescale social housing programmes.

Jack Taylor, Allume Energy’s General Manager for Europe, plays a central role in developing the SolShare offer and leading its expansion into the European market. With a background in engineering, recruitment, and startup innovation, he joined Allume driven by a commitment to delivering technology that benefits both people and the planet.

Ramin Hakimov, Allume’s Head of Business Development, brings over a decade of experience in the renewables sector, spanning EV charging and green energy. As the first employee of Allume UK, he has been instrumental in establishing the UK operation and advancing the rollout of SolShare across Government‑funded retrofit programmes.

This series aims to explore the individual stories and experiences of successful retrofit projects from the perspective of key suppliers. This covers a range of themes from technology use through renewable energy and low carbon heating to the career progression and skill development that projects are enabling.
