If you run a warehouse, workshop, or factory, you already know how much lighting matters. It affects productivity, safety, and energy costs — and with older systems, those costs can be eye-watering.
Switching to LED lighting is one of the most effective ways to reduce energy use, improve visibility, and create a better working environment. But upgrading a large commercial space isn’t as simple as changing a few fittings. It takes planning, design, and the right installation approach to get it right.
Here’s what’s involved in a proper warehouse or factory lighting upgrade — and how we handle it for businesses across Basingstoke and Hampshire.
Step 1: Lighting survey and energy assessment
The process starts with a full lighting survey of your building. We’ll measure existing light levels, look at how your space is used, and identify where improvements can be made.
This includes:
- Assessing current fittings, mounting heights, and layout
- Measuring light levels (lux) in key areas such as workstations, storage, and loading bays
- Reviewing energy consumption, running hours, and maintenance costs
- Checking emergency lighting and safety compliance
From there, we can estimate your current energy use and calculate potential savings with LED replacements.
Step 2: Lighting design and specification
Next comes the design stage. Good lighting isn’t just about brightness — it’s about providing the right light, in the right place, at the right level.
We’ll design a layout that meets the latest standards (CIBSE and HSE guidance), ensuring adequate light levels for each task while reducing waste.
That might include:
- High-bay LED fittings for open areas and racking zones
- Low-bay or linear fittings for workshops and production lines
- Task lighting for workbenches or inspection areas
- Emergency lighting integrated into the design
We’ll also plan for daylight sensors, occupancy controls, or zoning — to make sure you’re not lighting empty spaces unnecessarily.
Step 3: ROI and proposal
Once the design is complete, we’ll show you exactly what you stand to gain.
You’ll receive a proposal that includes:
- Estimated annual energy savings
- Predicted payback period (often 18–36 months)
- Carbon reduction figures
- Details of fittings, controls, and warranties
This gives you a clear, evidence-based case for investment — ideal if you’re reporting on ESG goals or managing a capital improvement budget.
Step 4: Installation planning and safety
Warehouse lighting upgrades need careful coordination to avoid disrupting operations.
At GU Solutions, we plan installations around your schedule, working during off-peak hours, weekends, or in stages to keep your site running.
We handle all aspects of safety, including:
- Isolating power and securing work areas
- Using access equipment and certified installers
- Disposing of old fittings responsibly
- Testing circuits and emergency systems before handover
All work is carried out to the latest BS 7671 Wiring Regulations, with full testing and certification provided on completion.
Step 5: Controls and automation
Adding lighting controls can make a big difference to your energy savings. We can include:
- Occupancy sensors that switch lights on only when areas are in use
- Daylight sensors to automatically dim fittings based on natural light levels
- Zoning and smart controls so different areas can operate independently
For larger facilities, we can install networked control systems that monitor usage and performance — giving you full visibility of where energy is being used.
Step 6: Handover, testing, and documentation
When the installation is complete, we’ll test and commission every circuit and fitting. You’ll receive:
- Full electrical test results and certification
- Emergency lighting logbook updates
- Manufacturer warranties and data sheets
- Energy savings report for your records
We’ll also demonstrate how the lighting controls work and ensure your team is comfortable managing the new system.
Why upgrade to LED?
For most warehouses and factories, LED lighting delivers:
- Energy savings of up to 70%
- Reduced maintenance and downtime
- Brighter, more consistent light levels
- Better visibility and improved safety
- Lower carbon emissions
- Compliance with modern efficiency standards
It’s one of the rare investments that improves working conditions while cutting costs at the same time.
