The Gap Project Limited was founded on a simple mission: to close the gap between inefficient buildings and a sustainable, low-carbon future. We saw too many homes suffering from draughts, high bills, and discomfort — and too many support schemes being underutilised. We resolved to bring technical excellence, integrity, and accessible solutions to this sector.

A UK where every building is energy efficient, comfortable, and low in carbon.

To empower homeowners and businesses to upgrade, retrofit, and future-proof their properties affordably and reliably.

We are engineers, retrofit assessors, installers and support staff who believe in:

Integrity & transparency

No hidden costs honest advice.

Quality & performance

We use proven materials and methods.

Innovation & sustainability

We keep up with green technologies and best practices.

Customer focus

We treat your property like it’s our own.

We hold certifications and accreditations (e.g. TrustMark, PAS 2030, Gas Safe) and follow industry standards to ensure every installation is safe, effective and guaranteed.

We operate across the UK. We serve domestic properties and assist clients through government incentive programmes, including ECO4, GBIS and others.

We believe in doing business responsibly. Beyond saving energy and reducing carbon, we aim to uplift communities, assist vulnerable households, and ensure quality installations — closing not just energy gaps, but also social gaps.
