Cost: interior lighting
Costs depend on supplied fittings, drivers, controls, new routes and finishes. Installation-only and complete supply-and-fit offers are different scopes. Detail zones and exclusions; recessed spots are not automatically the cheapest option.
Editorial update on 18 September 2026
List supplied equipment
Separate fittings, any replaceable sources, drivers, strip profiles and controls. Identify customer-supplied items and installer scope limits.
Assess fitting and making good
Separate routes, drilling, height access, removal, ceilings, patching and paint. Per-point prices alone cannot compare different scopes.
Compare future use
Ask about spares and maintenance access. Estimate consumption from model data and your operating hours; generic averages guarantee neither annual savings nor actual life.
