At 21 Degrees, we believe our built environment should be designed for optimal efficiency, health and comfort.

Our mission is to empower homeowners, architects, and businesses with the knowledge and technology to harness sustainable energy from every building and help safeguard the planet Our specialist products and services include renewable technology such as solar panels, heat pumps, battery storage and energy efficient upgrades such as triple-glazed windows and doors, mechanical ventilation with heat recovery (MVHR) systems, and insulation and airtightness products.

Our company’s foundations are built upon the proud history of our combined subsidiary companies including Green Building Store founded in 1995 and award-winning renewable installation company Green Building Renewables.

We have been at the forefront of sustainable, low energy building, offering product innovations and services for three decades. And we have helped to support the uptake of Passivhaus in the UK since 2007. In 2010, we completed construction on the UK’s first cavity wall Passivhaus at Denby Dale.

Today, 21 Degrees stands as a leader in the energy revolution, driven by our unshakable commitment to challenge outdated systems and champion sustainable living. Every home, business, and industrial facility we touch is not just built to meet expectations – it’s designed to exceed them, setting a new standard for energy performance, environmental stewardship, and human wellbeing.

Our world is changing, and the opportunity is now. Change the way you think about energy.
