About Us

Our Story

Based in Bath since our inception in 2006, Quidos is a leading quality-focussed and government approved accreditation scheme.

During that time, we have been active and vocal proponents for change within the energy efficiency sector.

Being a close-knit team, we’re able to provide good quality support to our assessors, whilst building professional relationships to support their work and develop a better understanding of the sector.

“Excellence is not an act, but a habit” – by working to help better our assessor’s professional knowledge, we see much better outcomes from the work they produce.
