For commercial, industrial and public-sector premises
Commercial & Industrial LED Lighting Upgrades in Scotland
Survey, plan and install LED lighting upgrades around how your premises actually works. WB Electrical reviews existing fittings, access, controls and electrical interfaces, then delivers the agreed upgrade with testing, commissioning and clear handover.
From our Larkhall base, we support lighting projects across Glasgow, Lanarkshire and the Central Belt. Suitable larger and multi-site projects elsewhere in Scotland are considered by agreement.
Surveyed properly. Planned around the site. Handed over clearly.
Know when an upgrade is worth investigating
When to Review Your Existing Lighting
Replacing fittings makes most sense when it solves a defined problem, such as poor light, frequent failures, high run hours, difficult maintenance or a layout that no longer suits the work below.
Ageing or unreliable fittings
Repeated lamp, driver or control failures and difficult high-level maintenance can make a planned upgrade more practical than continuing isolated repairs.
Lighting no longer suits the space
Dark areas, glare, shadows, changed layouts, new workstations or racking can mean the current positions and optics no longer match the tasks.
Energy and maintenance need review
Long operating hours, legacy fluorescent or discharge fittings and whole-area switching can justify comparing connected load, controls and maintenance against a modern option.
If the main issue is failed fittings or routine servicing rather than a planned upgrade, the separate Lighting Maintenance & Inspections route is the better fit.
Survey, electrical condition and a defined outcome
What an LED Lighting Upgrade Can Include
The agreed scope should make clear what is being retained, changed, installed and verified. It can range from selected replacements to a wider relayout, depending on the existing system and the outcome required.
Existing lighting and electrical review
Record fitting types, quantities, mounting heights, switching, controls, visible circuit and containment condition, recurring faults, access and how each area is used.
Upgrade option and lighting performance
Compare suitable luminaires, optics, output, colour quality and controls against the tasks and environment. Where needed, the scope can include lighting calculations or coordination with a specialist lighting designer.
Installation, testing and commissioning
Supply and install the agreed equipment, complete relevant electrical alterations, test the completed work, commission fittings and controls within scope, and provide the agreed handover records.
Emergency lighting, detailed smart-control projects, standalone external or security lighting, ongoing lighting maintenance and temporary lighting have their own service routes. Hazardous-area work depends on current site classification information and confirmed competence.
Access, phasing and live operations
Plan the Upgrade Around How the Site Operates
Mounting height, vehicle routes, production, public access, shift patterns and isolation limits can affect the method as much as the fitting. High-level work should be planned before installation, not treated as an afterthought.
01
Survey the site and operating constraints
Confirm the areas, activities, work windows, mounting heights, MEWP routes, permits, shutdown limits and any tasks that cannot safely continue while work is underway.
02
Agree the upgrade route and sequence
Compare retrofit, one-for-one replacement or relayout options, then agree access equipment, work zones, isolations, phasing, deliveries and temporary measures where required.
03
Install, verify and hand back
Complete the agreed electrical work, inspect and test it, aim and commission the new lighting or controls within scope, then confirm the defined outcome and hand over the agreed records.
Work at height must be properly planned, supervised and carried out by competent people using suitable equipment. The site-specific method may also need exclusion zones, pedestrian or vehicle controls, permits and emergency arrangements.
Need to plan access or phased working? Discuss your lighting upgrade with WB.
Know what is changing and why
Compare the Upgrade Route Before You Commit
A useful proposal should make the installed outcome clear
- Areas, tasks, existing problems and the required lighting outcome.
- Existing and proposed fitting types, quantities, layout, controls and any lighting calculation or verification included.
- Access equipment, isolations, phasing, traffic or work-zone controls, and relevant electrical interfaces.
- Testing, commissioning, product and warranty information, waste route, assumptions, exclusions and handover deliverables.
If energy or payback is modelled, keep the assumptions visible: existing and proposed connected load, realistic operating hours, control behaviour, tariff, maintenance assumptions and excluded areas. It is an estimate for the agreed scenario, not a guaranteed percentage.
Retain, replace or redesign
- Retain sound infrastructure where it remains suitable, supportable and compatible.
- Use retrofit solutions only where condition, thermal performance, compatibility and warranty implications are understood.
- Use one-for-one replacement where the existing positions and distribution still suit the tasks below.
- Relayout or redesign where glare, shadows, poor task light, difficult maintenance or changed use cannot be solved by a simple replacement.
The survey should establish the most practical route rather than assuming every fitting must be replaced.
If controls are part of the project: straightforward switching or sensor changes can be included where defined, while more involved zoning, daylight response or automation should route to Smart Lighting Controls.
Direct lighting evidence from working premises
Lighting Upgrades Across the Scottish Opera Estate
Scottish Opera
WB Electrical has supported Scottish Opera since 2015 across multiple Glasgow sites. The published case study records high-level and low-level lighting work, spotlights, low-energy fittings, battens, sensor lighting, emergency lighting and external lighting across rehearsal, production, workshop, storage and support areas.
The case study demonstrates lighting improvement and ongoing electrical support in occupied, mixed-use premises. It does not imply that every future lighting project has the same design, access method or scope.

Practical answers before you book
Commercial LED Lighting Upgrade Questions
How do you decide whether to retrofit, replace or redesign?
We start with condition, compatibility and the outcome you need. A retrofit may suit sound equipment, one-for-one replacement can suit a good existing layout, and a relayout or redesign is more appropriate where positions, optics, controls, glare, shadows or tasks need to change.
Can WB arrange MEWPs and work at height?
Yes, where appropriate to the agreed job. The access method still needs site-specific planning, suitable equipment, competent people, supervision and controls for the work area, pedestrians, vehicles, permits and emergency arrangements.
How are energy savings and payback estimated?
A useful estimate compares existing and proposed connected load, realistic operating hours, control behaviour, the client’s tariff and stated maintenance assumptions. Future energy prices, usage and operational changes mean the result should be treated as an estimate rather than a guaranteed universal saving.
Do you provide lighting design or lux calculations?
Where required, the scope can include lighting calculations, layouts or coordination with a specialist lighting designer, followed by an agreed verification method. Indoor workplace lighting design may refer to BS EN 12464-1:2021, depending on the premises and task.
What handover information can be included?
The agreed handover may include electrical certification or test records, fitting schedules, marked-up drawings, control settings, commissioning results, lighting verification where included, product and warranty information, maintenance guidance and photographs. The quotation should identify the exact deliverables.

Controls and automation
Plan occupancy, daylight, zoning or more advanced control arrangements as a defined controls project where the requirement goes beyond the upgrade itself.
Ongoing and external lighting needs
Keep maintenance, condition checks and external lighting requirements clear after the main upgrade is complete.
Share the site, lighting problem and operating constraints
Request an LED Lighting Survey
Tell us what you know about the areas, current lighting and the outcome you want. If fitting quantities, mounting heights or existing wattages are not yet known, we can establish what information or site survey is needed before pricing.
Information for your quotation
- Company or organisation, site address and postcode.
- Areas to upgrade, how they are used and the lighting problems to solve.
- Approximate fitting quantity, mounting height or floor area, if known.
- Existing lamp or fitting types, controls and recurring faults, if known.
- Operating hours, work windows, access constraints, permits and isolation restrictions.
Mention drawings, photographs, fitting schedules or energy information in the form. The office can confirm a suitable way to share them. Please do not access high-level fittings or remove electrical covers just to gather details.
What affects LED lighting upgrade cost?
Fitting quantity and type, mounting height and access, circuit or containment condition, controls, working hours, disposal and whether layout or design changes are needed all affect the price. A simple cost per fitting can hide project-specific work.
The next step may be a site survey, options proposal or quotation. Emergency lighting, advanced controls, hazardous-area work or wider electrical alterations should be identified and scoped separately unless expressly included.
Based in Larkhall, we support suitable commercial, industrial and public-sector lighting work across Glasgow, Lanarkshire and the Central Belt. Larger, specialist and multi-site requirements elsewhere in Scotland are considered by agreement.
