There is no reliable single price for emergency lighting installation in London because the cost depends on the actual building, the number and type of fittings, the existing wiring, access, occupancy and the work needed to create a suitable system. A small replacement job can involve a very different scope from installing emergency lighting throughout a multi-storey property.
The useful question is therefore not simply “how much per fitting?”
A meaningful quotation should define which areas need emergency lighting, what is already installed, what new wiring or alterations are required, how the work will be accessed and what testing or follow-up is included.
Key Takeaways
- RCD Electrical does not base an emergency-lighting quotation on room count alone.
- Building layout, fitting quantity and type, wiring routes, access and the condition of the existing system all affect the final scope.
- Replacement of existing fittings is normally a different project from designing and installing a new system.
- Current fire-safety requirements and emergency-lighting standards can affect where fittings are needed and therefore the work involved.
- A site-specific assessment is the most reliable way to obtain an accurate quotation.
Why Emergency Lighting Cannot Be Priced by Room Count Alone
Two properties with the same floor area can require very different emergency-lighting work. One may already have suitable wiring and only need selected fittings replaced, while another may need new cable routes, additional points, changes to existing circuits and emergency lighting across several escape routes or levels.
RCD Electrical's current emergency-lighting service therefore treats pricing as a site-specific quotation. The property layout, existing system, access arrangements and electrical scope are reviewed before the work is confirmed.
This approach also avoids a common pricing problem: a low headline figure may cover a fitting but not necessarily the wiring, access, testing, alterations or remedial work required to make the overall installation suitable for the building.
What Affects Emergency Lighting Installation Cost?
Building Layout
Corridors, stairs, changes of level, exits, shared areas and the arrangement of rooms influence where emergency lighting needs to be considered.
Number of Fittings
A larger or more complex layout may require more emergency luminaires and more installation points than a compact property with simple escape routes.
Existing Wiring and Supply
Reusing suitable existing wiring is a different scope from installing new cabling, creating additional points or altering electrical supplies.
Access to Wiring Routes
Ceiling height, concealed routes, finished surfaces and difficult access can change the labour and planning required to install fittings and cables.
Occupied Premises
Offices, shops and other operational properties may need work planned around staff, customers, restricted areas or agreed working hours.
Condition of Existing Fittings
An existing system may contain reusable fittings, failed batteries, damaged units or parts that need replacement before the final scope is clear.
Testing and Completion
The quotation should make clear what testing, commissioning checks and project documentation are included after the physical installation work.

Replacing Existing Emergency Lights vs Installing a New System
Replacing failed fittings on an existing suitable installation is usually a narrower scope than creating emergency lighting where no suitable system currently exists. A new installation may require planning the fitting positions, selecting suitable equipment, providing wiring routes, connecting the system and completing the required checks.
Existing systems can also introduce unknowns. A failed light may be caused by the fitting or battery, but a wider supply or circuit issue may need investigation before replacement alone can be recommended.
For this reason, a quotation should distinguish between straightforward replacement, alterations to an existing system and a completely new installation rather than combining all three under one generic “per light” rate.
Current Standards Can Change the Installation Scope
An older emergency-lighting specification should not automatically be treated as the current design benchmark. As of August 2026, BS 5266-1:2025 is the current BSI code of practice for emergency lighting of premises, replacing BS 5266-1:2016 in October 2025. BS EN 1838:2024 and BS EN 50172:2024 are also current parts of the emergency-lighting standards framework.
These standards affect technical design and system requirements rather than providing a fixed London installation price. Their practical importance for cost is that a correct assessment may identify different fitting positions, coverage or system requirements from those assumed in an informal “number of rooms × price per light” calculation.
For non-domestic premises in England, the fire risk assessment is also relevant to the areas requiring emergency escape lighting. GOV.UK guidance states that emergency lighting is needed where necessary for escape routes and exits that depend on artificial illumination.
The detailed legal and standards question belongs to the dedicated guide on
legal requirements for emergency lighting installation in London.
What Should an Emergency Lighting Quote Include?
A useful quotation should make the project boundary clear enough that you can see what is being installed and what could create additional work later.
- the areas included in the project;
- whether the work is a new installation, alteration or replacement;
- the proposed emergency-lighting fittings or system arrangement;
- new wiring or circuit work included in the scope;
- access assumptions and any restrictions;
- testing and commissioning work included;
- any known repairs or remedial work;
- items excluded from the electrical scope, such as separate decorative making-good where applicable.
Existing emergency-lighting test records, building plans and clear photographs can help establish the scope before attendance, but a more complex property may still need an on-site review.
Does Ongoing Testing Affect the Overall Budget?
It can. Installation cost is only one part of managing an emergency-lighting system. The system also needs appropriate ongoing checks and maintenance so failed fittings, battery problems and other defects can be identified.
GOV.UK fire-safety guidance for offices and shops recommends regular emergency-lighting checks and competent-person testing and maintenance. The full testing process and ongoing maintenance schedule are covered separately in the guide to
emergency lighting testing in London.
Keeping installation and maintenance costs separate also makes quotations easier to understand: the initial project can be priced for the agreed installation, while future inspection and maintenance can be planned according to the building and system.
How to Get a More Accurate Emergency Lighting Quote
Start with the information that affects the work rather than asking only for a price per fitting. Provide the property postcode and type, which areas are included, whether emergency lighting already exists, any known failed fittings and details of access or operating-hour restrictions.
If available, also provide previous test records, plans or photographs. These details help establish whether the project is mainly replacement work, an alteration to an existing system or a new installation.
Where the final layout or electrical scope still needs to be established,
arrange an emergency lighting assessment
before relying on a fixed budget figure.
