What Makes Us Different

We’re independent..
We’re independent, qualified, and evidence-led. Our work draws on nearly four decades of professional lighting experience, continuing research, and active involvement in industry standards and professional committees.

We see what others miss..
We look beyond lumens and lux. Our evidence-led approach considers visual performance, comfort, timing, spectral characteristics, energy, ecology, and the people and animals affected by light. We distinguish established guidance from emerging research and translate both into responsible, practical recommendations.

We speak lighting and planning..
“We speak lighting and planning, health, ecology, design, and compliance fluently.” Use us early to reduce issues later on, its never too early for a lighting designer to be involved.

If you want more than light fittings on a drawing..
“If you want more than light fittings on a drawing, you’re in the right place.” Our designs are fully integrated with other disaplines and shape the evolution of your project from the start. We don’t just produce a layout, we produce a fully thought through design.

Our Ethos

At it does Lighting Ltd, we believe that light should do more than simply illuminate. It should serve the task, enrich the experience of place, support people and animals, and protect the natural environment, indoors and out, by day and after dark.

With nearly four decades of award-winning experience, our ethos is rooted in scientific integrity, independent thinking, and a deep respect for the interplay between light, biology, and the built environment.

We champion thoughtful design over quick fixes and always advocate for solutions that are as responsible as they are remarkable.

Our Mission

Our mission is to deliver independent lighting design and consultancy that supports people, animals, communities, and the natural environment. Whether guiding policy, training professionals, reviewing existing places, or shaping new developments, we bring evidence, professional judgement, and responsible innovation into every project.

Through education, research, design, and collaboration, we help clients make better lighting decisions across the 24-hour day. We balance visual quality, safety, wellbeing, energy, ecology, architecture, maintenance, and long-term social value, while recognising the importance of appropriate daylight and darkness.
