Lighting for offices, retail, hospitality and commercial premises
ZJ Electrical Services installs and upgrades commercial lighting for offices, shops, restaurants, hospitality venues and other business premises across East London.
From replacing inefficient or outdated fittings to installing new lighting layouts, feature lighting and suitable controls, we plan the electrical work around the premises, existing installation and way the space will be used.

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.
New lighting circuits and fittings for commercial spaces, refurbishments and revised layouts, planned around the premises and intended use.
Replacement of older or inefficient lighting with suitable LED fittings, considering output, fitting type, colour temperature, controls and compatibility with the existing installation.
General, accent and feature lighting for shops, opticians and customer-facing spaces where lighting contributes to both visibility and the finished interior.
Lighting installations and upgrades for offices and workspaces, including general lighting and appropriate controls for the way the space is occupied.
Switching, dimming and lighting controls where suitable for the fittings, drivers and project requirements.
Emergency-lighting installation and alterations can be included where required as part of the agreed commercial electrical scope.
Modern LED lighting can reduce electrical demand compared with older lighting technologies, depending on the existing installation and replacement fittings.
Suitable LED fittings can reduce lamp replacement and maintenance compared with older lamp-based systems.
A correctly selected fitting and layout can improve illumination, visual comfort and how a commercial space presents to staff and customers.
Suitable controls can reduce unnecessary operating time and provide more flexibility for different areas or uses.
For larger or specification-led projects, lighting information supplied by the fitting manufacturer, designer or project team can be incorporated into the electrical installation.
Compatible dimming where the fittings and drivers support it.
Automatic control may be appropriate for areas such as circulation spaces, stores, WCs or intermittently occupied rooms.
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.
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 installation and alterations coordinated with the space and existing electrical installation.
The work needed to provide suitable illumination while minimising unnecessary disruption to the business.
A completed lighting installation integrated into the finished retail environment.
Images of the existing lighting, ceiling and electrical installation.
Drawings or marked-up layouts showing the areas to be changed.
Details of fittings already selected by the client/designer, where applicable.
Requirements for switching, dimming, occupancy controls or other control methods.
Ceiling height, access restrictions and whether equipment such as steps, towers or specialist access may be required.
Preferred timescale and whether the work must be coordinated with refurbishment or trading hours.
A site visit may be required for larger or more complex commercial lighting projects before a final quotation is prepared.
Best for: Like-for-like maintenance where the existing fitting and electrical installation remain suitable.
Best for: Replacing outdated or inefficient fittings with suitable new LED fittings while retaining much of the existing layout.
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.

Based in Leyton, ZJ Electrical Services carries out commercial lighting work across East London and surrounding areas including Walthamstow, Leytonstone, Hackney, Wanstead, Highams Park and Woodford.
For larger projects, send us the site location, photos and project details so we can review the scope.
Yes, where suitable. The existing fittings, circuit arrangement, controls and required light output should be considered before deciding on the best replacement approach.
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.
It depends on the premises and scope of work. Where practical, work can be phased and known interruptions or access requirements discussed in advance.
Yes. Lighting, controls, new circuits and related electrical alterations can form part of a wider commercial fit-out or refurbishment project.
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.
Yes. Where fittings have already been specified, we can review the available technical information and electrical requirements before installation.
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.
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.
