Energy efficient upgrades in Norwich

Originally founded as Inspired Renewables and rebranded to Green Building Renewables in 2023, we evolved to become 21 Degrees in November 2024.

Whether you need a single product or the ultimate Passivhaus, your system needs to be well thought out and designed correctly. We adopt a full-circle approach to provide better performing buildings from a carbon, cost, and comfort perspective to get you the right outcome

Our specialist products and services include renewables such as solar panels and heat pumps, and energy efficient upgrades such as triple-glazed windows and doors, mechanical ventilation with heat recovery (MVHR) systems, and insulation and airtightness products.
