What is Energiesprong?

Energiesprong is a revolutionary, whole house refurbishment and new build standard and funding approach. The mission of Energiesprong UK is to scale this approach in the UK market.

Sign up to our mailing list for the latest news and insights into scaling deep retrofit in the UK.

The Energiesprong standard focuses on creating desirable homes that people love to live in. Because an Energiesprong retrofit (or new build) has the very best energy standard available, it uses the money that would normally be paid on energy bills and maintenance to pay for the works.

The Energiesprong approach can do this while assuring the cost of living does not go up, because the standard guarantees real life performance for both indoor comfort and energy use for up to 40 years.

Finally, and because desirability is at the forefront of what Energiesprong is about, the retrofits are also quick to install: a complete house makeover should take less than 10 days.

Read more about the approach in this Green Alliance report.

Energiesprong UK's mission

Energiesprong UK uses the social housing sector as the launching market for these solutions, with a view to later scale to the private homeowner market. 

The independent Energiesprong UK market development team aggregates mass demand for high quality retrofits (and new build houses) and drives the right financing and regulatory conditions in parallel. With these in place, solution providers can go into a quick and transformative innovation process to deliver against this new standard.

Our awards

Energiesprong is on an award-winning streak. In 2018, Energiesprong won the World Green Building Council award for innovation and Nottingham’s Energiesprong homes won a UK Housing Award and Shift Award.

In 2019 Energiesprong´s E=0 and Transition Zero projects won an EU Sustainable Energy Award in Brussels, the Nottingham pilot won Project of the Year at the Energy Efficiency & Retrofit Awards (East Midlands), while Energiesprong UK won the prestigious Ashden Award in the UK Sustainable Buildings category. Solution provider Melius Homes also won a Construction News Award for the Energiesprong retrofits in Nottingham.

Media coverage and research

Recent reports from the Institution of Engineering and Technology and the Green Alliance point to Energiesprong as the way forward.

Transition Zero / H2020

Under the name Transition Zero, Energiesprong UK executed a European Union Horizon 2020-funded project to set the right market conditions. ‍

The Transition Zero project focused on:‍

•   Developing the business model in the UK

•   Studying and improving regulation

•   Developing the performance guarantee model

•   Optimising financing solutions

•   Studying public procurement options

•   Assisting housing associations and solution providers in innovating and developing offers

•   Creating a volume deal.

E=0 / Interreg

The North West European Interreg E=0 project supported the development of an initial set of demonstrators in the UK. This support consists of co-funding the first Energiesprong makeovers, expanding the movement in general and supporting the development of better solutions. E=0 focuses on developing and implementing retrofits for 20 demonstrators and analysing the performance of these.


Mustbe0 builds further on the knowledge and experience gained by Interreg NWE E=0 project that was mainly focussed on single family homes. In the Mustbe0 Interreg North West European project, 9 housing providers in the UK, France, Germany and the Netherlands have already committed to collaborating on the retrofit of at least 9 demonstrator buildings (415 apartments). This will launch the market.

The European Interreg NWE “Mustbe0” project has a total budget of 34 million euros and is supported by the European Union through the European Regional Development Fund (ERDF) for 11 million euros.
