Commercial lighting for different premises
Lighting requirements vary considerably between workplaces, retail spaces, hospitality environments and customer-facing premises. The layout, fitting type, colour temperature, controls and existing wiring all affect the final installation.

Commercial lighting services
LED lighting upgrades
Replacement of older or inefficient lighting with suitable LED fittings, considering output, fitting type, colour temperature, controls and compatibility with the existing installation.
Retail & display lighting

Office lighting
Lighting installations and upgrades for offices and workspaces, including general lighting and appropriate controls for the way the space is occupied.
Lighting controls & dimming
Switching, dimming and lighting controls where suitable for the fittings, drivers and project requirements.
Emergency lighting
Emergency-lighting installation and alterations can be included where required as part of the agreed commercial electrical scope.
Why businesses upgrade their lighting
Energy use
Modern LED lighting can reduce electrical demand compared with older lighting technologies, depending on the existing installation and replacement fittings.
Maintenance
Suitable LED fittings can reduce lamp replacement and maintenance compared with older lamp-based systems.
Lighting quality
A correctly selected fitting and layout can improve illumination, visual comfort and how a commercial space presents to staff and customers.
Controls
Suitable controls can reduce unnecessary operating time and provide more flexibility for different areas or uses.
Choosing the right commercial lighting
Fitting selection
- Light output
- Beam/distribution
- Colour temperature
- Colour rendering where relevant
- Fitting style
- Environment
- Compatibility with dimming/controls
Installation considerations
- Existing circuits
- Cable routes
- Switching
- Emergency-lighting requirements where applicable
- Ceiling type
- Access
- Maintenance
- Project programme
For larger or specification-led projects, lighting information supplied by the fitting manufacturer, designer or project team can be incorporated into the electrical installation.
Lighting controls that suit the space
Dimming
Compatible dimming where the fittings and drivers support it.
Occupancy / presence control
Automatic control may be appropriate for areas such as circulation spaces, stores, WCs or intermittently occupied rooms.
Timed or scheduled control
Suitable controls can help prevent lighting being left on unnecessarily and support planned operating hours.
Control compatibility must be checked against the selected fittings and drivers to avoid issues such as flicker, poor dimming performance or unreliable operation.
Lighting as part of a fit-out or refurbishment
Commercial lighting is often only one part of a wider project. New layouts may require revised switching, additional circuits, altered cable routes, emergency-lighting changes or coordination with ceilings, joinery and other trades.
Where lighting forms part of a larger refurbishment, the electrical work can be coordinated with the wider fit-out programme. See our Commercial Electrical Fit-Outs & Refurbishments service.

Lighting upgrade or complete lighting alteration?
Lamp / simple fitting replacement
Best for: Like-for-like maintenance where the existing fitting and electrical installation remain suitable.
Lighting upgrade
Best for: Replacing outdated or inefficient fittings with suitable new LED fittings while retaining much of the existing layout.
Lighting alteration / new installation
Best for: New layouts, additional fittings, new circuits, revised switching or substantial refurbishment work.
The correct approach depends on the condition of the existing installation, required lighting outcome and project scope.

Commercial lighting FAQs
Can you replace fluorescent lighting with LED fittings?
Yes, where suitable. The existing fittings, circuit arrangement, controls and required light output should be considered before deciding on the best replacement approach.
Can you install dimmable commercial lighting?
Yes, where the selected fittings and drivers are compatible with the proposed dimming system. Compatibility needs to be checked to avoid issues such as flicker, buzzing or poor dimming performance.
Can lighting be upgraded while our business remains open?
It depends on the premises and scope of work. Where practical, work can be phased and known interruptions or access requirements discussed in advance.
Can you install lighting as part of a shop or office refurbishment?
Yes. Lighting, controls, new circuits and related electrical alterations can form part of a wider commercial fit-out or refurbishment project.
Do you install emergency lighting?
Emergency-lighting installation and alterations can be included where required as part of the agreed commercial electrical scope. The requirements depend on the premises and project.
Can you work with fittings selected by our architect or designer?
Yes. Where fittings have already been specified, we can review the available technical information and electrical requirements before installation.
Do you supply the lighting fittings?
This depends on the project. We can discuss whether fittings are to be supplied by ZJ Electrical Services, the client or another member of the project team before quotation.
Planning a commercial lighting project?
Send us photos, drawings or details of the existing lighting and tell us what you want to improve. We can review the electrical scope, fitting requirements, controls and access before preparing a quotation.
