Ronan Leyden

Programme Director

With 18 years’ experience in the sustainable built environment, I’m helping Energiesprong UK scale its consultancy offer to help scale retrofit in a cost-effective and financeable way.

What I do at Energiesprong UK

I’m focused on supporting ESUK to deliver some of its current grant-funded projects, as well as scaling our support services for asset owners and landlords to outcome-led retrofit at scale and within budget.

I work with housing providers, building firms, supply chain and policymakers to tackle the sector’s biggest barriers – unlocking real-world performance, providing a strong financial case and simulating innovation.

This includes leading on our involvement with the Mayor of London’s Zero Carbon Accelerator,  a new programme that will transform the organisations’ ability to decarbonise and meet London’s net zero target by 2030.

What I did before Energiesprong UK

I’ve got more than 18 years of experience in sustainability in the built environment sector, specialising in UK housing; much of which I was leading the consultancy services for award-winning sustainability consultancy and environmental charity Bioregional.

I’ve previously worked with housing associations, local authorities, estates and asset owners to develop sustainability solutions to existing and new build homes and buildings. I’ve also led a number of grant funded research projects in this area.

I’m a certified Retrofit Co-ordinator, trained in Energy Efficiency for Older and Traditional Buildings, holds a Post Graduate Diploma in Housing and City Planning, an MSc in Design for Sustainability, and a BSc in Physics and Philosophy.
