Innovative energy efficiency: helping you save the energy you don't use

ON5 Group is an optimistic brand, offering easy-to-implement energy efficiency tools as a means for individuals and corporations to reduce their carbon footprint, in the face of a changing climate.
To achieve this, we are tapping into an inexhaustible energy source - the cleanest and cheapest available - energy we don't use. Inspired by the primary energy sources: the sun, the moon, the earth and the atom, we call this unused energy the 5th energy. This is why we are ON5.

We have been at the cutting edge of the energy transition for 10 years. We can only do it together.


We empower individuals and corporations by providing them with the knowledge and tools they need to improve their energy efficiency.

What makes us different? We put digital techniques in human hands to achieve concrete solutions. Through constant innovation, we use our skills and passion for energy efficiency to create links with and amongst our stakeholders - people, companies, landlords and local authorities - alongside our clients and partners. Our motivation to build a low-carbon future, has led us to successfully develop over 100 platforms and completed over 500,000 renovation projects.

As pioneers of energy efficiency, we have become leaders in the European ecosystem thanks to our expert know-how, groundbreaking platforms and learning tools. With our vast experience across Europe, we are ideally positioned to expand internationally; we continually renew our offerings and tailor our services to suit every country in which we expand.

The 5th Energy


ON5 is named after the 5th energy - the one we don't use. According to the law of physics, energy comes from four sources: the atom, the sun, the moon and the earth.

The 5th energy is unused energy, unconsumed energy, energy saved - in its essence, it creates zero greenhouse gas (GHG) emissions and is free. ON5 aims to help people tap into this 5th energy by implementation energy efficiency through various tools - in order for them to help save money and the planet.

A European Group

Energy transition is a Europea-wide challenge.


Over 170 million EU homes overconsume energy and an estimated 15-20 million households live in fuel poverty. Building on its experience in France, ON5 Company is taking its range of services to other European countries.
