Our mission is for every UK home to be desirable, comfortable, affordable and fit for 2050 net-zero standards.

We work with local authorities, housing providers, building firms and the supply chain to:

Our vision – outcome-led retrofit for net-zero homes and comfortable tenants

Inspired and informed by a decade of testing the Dutch Energiesprong (“Energy Leap”) model in the UK market, we champion outcome-led retrofit.

This means creating homes that look great, perform in-line with their net-zero targets and result in comfortable tenants who can afford their energy bills.

To achieve this, we are pushing the boundaries to help scale a UK retrofit market that:

  • Offers actual verified, real-world performance and is compatible with a future zero-carbon energy system that’s electrified, grid-friendly and uses no natural gas
  • Provides a strong financial case for investors, landlords and funders with rapid and cost-effective retrofit solutions
  • Stimulates innovation and investment for a modernised, thriving and collaborative retrofit industry.

What we do

Support local authorities and social landlords to develop and deliver outcome-led retrofit projects, including managing large-scale, multi-stakeholder, collaborative programmes.  

This ranges from project development, grant applications and defining strategies through to archetype-based stock assessment, procurement advice, delivery, tenant engagement and ongoing performance monitoring.

Help social landlords to create a robust business case for retrofit schemes using our ‘Comfort Plan’ approach alongside other finance streams.

A comfort plan replaces some or all a tenant’s energy bill post-retrofit and is underpinned by a performance guarantee that promises them a comfortable, healthy home for the same (or less than) they paid before.

Assist organisations in the construction sector to understand what they need to do to deliver successful net-zero home refurbishment programmes with outcome-led retrofit.

This includes support to test and develop next generation retrofit strategies, tools and models, quality assurance, tenant engagement advice and ongoing performance monitoring.

Enable the supply chain to get cost-effective, high performance retrofit solutions to the market across fabric, energy, ventilation and cooling.

We can offer procurement and quality assurance support, supplier and landlord matchmaking and performance verification and monitoring.

Inspire sector change by showcasing real-life examples of transformation through industry events, study tours and communications campaigns.

We share open insights and lessons learned, foster new connections, and make policy recommendations to address the sector’s key challenges, including underperformance, poor quality, and lack of collaboration.
