GIA Equation was first established in 1984, one of the pioneers of independent lighting design in UK. Over the last 25 years we have evolved into a major practice with involvement as a key consultant on a wide range of UK and international projects.

We understand the psychology of light and how it influences people’s wellbeing and perception of their environment. Our creative design platform, coupled with an innovative approach and a technically sound foundation, offers an essential ingredient for the success of our client’s projects.

As a professional lighting design consultancy, we have no alliance with any manufacturer, supplier or installer of lighting equipment. Our advice is completely impartial, providing the very best value for each project.
