Most office lighting was designed around electricity bills, not people. We audit and fix it — reducing fatigue, improving comfort, and creating conditions where staff can actually do their best work.
Most offices have lighting that was installed to meet a minimum standard and then never revisited. It's not broken — but it's almost certainly not right either. Uneven brightness, harsh glare, screens that strain the eyes, and light that quietly works against how the body wants to function across the day.
The effects show up slowly: afternoon energy dips, persistent headaches, screen fatigue, disrupted sleep, people feeling worn out by Wednesday. These aren't just personal quirks — they're predictable responses to a poorly managed light environment.
The good news is that this is fixable. But you need to know what you're actually dealing with first. That's what we do.
Understand the science behind thisConstant, flat overhead light all day gives the body no cues about time. Energy dips that feel inevitable are often an environmental problem, not a personal one.
Glare from windows or overhead fixtures, combined with screen brightness mismatches, forces the visual system to constantly adapt — leading to headaches and concentration loss by mid-afternoon.
Desks near windows and those in the centre of the floor can sit in completely different light environments. The same tasks, under very different conditions.
Blue-light glasses, improvised window shading, desk lamps dragged in from home — when people start modifying the environment themselves, the environment is telling you something.
The light people are exposed to during the day affects how well they sleep at night. A poorly lit office can disrupt rest long after the working day has ended.
Staff costs typically represent over 80% of operating expenditure. A meaningful improvement in focus, energy, or sickness absence — even a modest one — generates a return on a lighting investment that is straightforward to calculate. Research in this space is growing, and several findings from the peer-reviewed literature are worth knowing about.
Office workers in environments with better daytime light exposure slept an average of 46 minutes more per night and scored significantly higher on vitality measures — tracked using validated clinical instruments.
A workplace lighting study found an 84% reduction in reported headaches and a 73% reduction in eye strain, alongside improvements in alertness and mood, after lighting was adjusted for the working day.
Published research links disrupted daily light cycles to measurable reductions in attention, working memory, and decision-making quality. The mechanism is well understood in biology; the workplace applications are increasingly documented.
For a team of 50 people, a 1% improvement in productive output — roughly 5 minutes per person per working day — covers the cost of a full audit and lighting intervention in a matter of weeks. The question isn't whether better lighting is worth it. It's why it's been left this long.
We visit your office and take detailed readings at desk level — light intensity, colour quality, glare, screen brightness ratios, and flicker characteristics. We also talk to staff about what they actually experience. You can't improve what you haven't measured.
You receive a written report in plain English — what we found, what's causing it, and what the priorities are. We benchmark against WELL Building Standard criteria, and we explain what that means in practice, not just as a compliance score.
Using specialist knowledge of lighting physics, fixture design, and how light interacts with human biology across the working day, we design a tailored plan — ranging from targeted adjustments to a full system redesign, depending on what the space actually needs.
We manage any installation work with specialist fixture suppliers. Where hardware isn't the immediate priority, we can begin improving the screen environment through software from day one — the quickest wins are often there.
For most office workers, the screen is the closest and most constant light source they're exposed to all day. We deploy IRIS — screen optimisation software — as part of our full environment approach. It adjusts screen colour and brightness automatically throughout the day, eliminates screen flicker, and reduces blue light exposure at source. It can be rolled out across a whole team quickly and complements the physical lighting work we do around it. iristech.co
Betong Skateparks run a design studio in Hackney. Their office is a typical London creative workspace — screen-heavy work, suspended LED strip lighting overhead, and significant natural light from window-facing desks.
On paper, nothing about that sounds alarming. In practice, staff had been quietly adapting to a difficult visual environment for some time — without anyone connecting the light to the discomfort.
Our post-occupancy audit found a clear and consistent set of issues. None required a complete overhaul. Most were addressable through targeted, proportionate changes — and the report gave Betong a precise picture of where to focus.
"The visual environment is currently being informally adapted by occupants. Proportionate improvements to glare control, lighting balance, and screen-environment interaction could significantly improve day-to-day comfort without necessarily requiring full lighting replacement."
The suspended LED strip lights showed flicker characteristics that, while often below the threshold of conscious perception, are associated with visual fatigue and headaches over prolonged exposure.
IdentifiedSignificant variation in lux readings across different workstations — meaning staff are doing the same visual tasks under materially different light conditions depending on where they sit.
IdentifiedStaff reported ongoing glare from window-facing positions throughout the day and across seasons. Improvised shading — applied by occupants themselves — had become a permanent fixture, which is a reliable signal the problem hasn't been addressed at source.
IdentifiedOne staff member was observed wearing blue-light filtering glasses during screen work. Reports of increased afternoon fatigue during prolonged screen use were consistent across the team.
IdentifiedThe existing layout does not need stripping out. Targeted interventions — glare management, flicker elimination, lux balancing, and IRIS screen software — can resolve the core issues within the existing structure at a fraction of a full refit cost.
Recommended pathEvery audit includes an on-site visit, desk-level measurements across all zones, staff interviews, and a full written report with prioritised recommendations. The price reflects the size of the space — larger offices require more measurement points, more time on-site, and a more detailed report.
The report stands on its own. You're not committed to any installation work by commissioning an audit. Many clients use the findings to inform facilities decisions, WELL certification processes, or landlord negotiations — independently of any lighting changes.
