Dedicated to accelerating London's sustainable energy transition
feral-labs was founded in 2014 by a group of energy engineers and environmental scientists who saw a gap between the sustainability ambitions of London businesses and the practical expertise needed to achieve them.
What began as a small consultancy focused on energy audits has grown into a comprehensive advisory practice serving commercial properties, manufacturing facilities, hospitality venues, and corporate offices across the capital.
Our approach combines rigorous technical analysis with pragmatic implementation support. We understand that businesses need solutions that work within real-world constraints of budgets, operations, and timelines.
Every recommendation we make is grounded in measured data, industry research, and proven methodologies. We avoid speculation and focus on what demonstrably works.
Sustainability initiatives must make business sense. We prioritise interventions that deliver measurable returns and align with your financial planning cycles.
Energy transition is a journey, not a project. We build lasting relationships with clients, providing ongoing support as their needs evolve and technologies advance.
Our team holds professional certifications including ESOS Lead Assessor, BREEAM Assessor, and Low Carbon Consultant credentials. Several consultants have backgrounds in building services engineering, with experience designing energy systems for major commercial developments.
We maintain active memberships in the Energy Institute, CIBSE, and the Association for Decentralised Energy. This keeps us connected to the latest research, regulatory developments, and emerging technologies in the sustainable energy sector.

The feral-labs team brought a level of technical depth that exceeded our expectations. Their renewable transition plan included options we hadn't considered, and their understanding of available grants saved us nearly £80,000 on our solar installation.
