A renovation lighting budget is rarely built from a specification. It is built from the last project's numbers, a per-key figure carried forward, or a supplier's indicative range, then defended line by line for two years. In a refurbishment the ground keeps moving: ceilings are opened, services are discovered, and fixture counts shift as rooms are re-measured.
This guide is for the people who must set that number before the specification exists: hotel owners, designers and project managers. It covers the cost drivers that move a decorative lighting allowance, the lines that belong inside the package, the allowances renovation teams leave out, and how to keep the figure defensible once tender starts.

Why a renovation lighting budget is not a price list
A budget is an allowance for a scope that is not yet fixed. A price list describes a scope that is. Confusing the two means the lighting line is re-opened every time the drawings move.
Three differences matter in practice:
- Purpose. A budget is built to be revised; a quotation to be held.
- Input. A budget is assembled from cost drivers; a quotation from line items.
- Timing and owner. A budget is set while rooms are still being measured; a quotation is issued against a frozen bill of quantities.
In a renovation the useful question is not what a wall light costs, but what it has to do in that room and what must change to deliver it. The second half carries the money.
The five cost drivers that move a decorative lighting allowance
Most of the variance between a low and a high allowance sits in five decisions, each easier to make early.
| Cost driver | What it covers | Why it moves a renovation figure |
|---|---|---|
| Fixture mix | Distinct decorative types per room type, not the total count | Every added type carries its own drawing, sample and finish setup |
| Material and finish route | Base metal, finish family, shade material, diffuser type | A late substitution resets the sample, the batch and its evidence |
| Degree of customisation | Dimensions, silhouette and any functional content | A functional change after sampling invalidates the approved piece |
| Control and charging content | Switch or dimmer, driver, charging modules, addressing | These parts have different owners, so answers arrive late |
| Release schedule and packaging | Delivery drops, storage between phases, export packing | One sealed drop is cheaper, and rarely fits a live renovation |
Mix, not count, is the driver teams underestimate. Two hundred identical corridor sconces across six floors behave like one type; six room types carrying four fixtures each behave like twenty-four, with more drawings, samples, finish batches and spares.
Choosing the frame: per key, per room type or per package
Every allowance is expressed in one of three frames, and the frame decides what the number can hide.
| Frame | Works well when | What it tends to hide |
|---|---|---|
| Cost per key | Feasibility and scheme comparison, before rooms are measured | That suites, corridors and public areas differ from a standard room |
| Cost per room type | Rooms are re-measured individually, as in most refurbishments | Public areas, back of house, and the items shared between them |
| Cost per package or zone | The fit-out is released in phases with separate completions | Shared items such as mock-up, spares and control gear |
Whichever frame is used, issue the allowance with its assumption list: fixture counts, material route, release drops. A number without assumptions cannot be checked, only renegotiated.
What belongs inside the lighting line and what sits outside it
Most budget arguments in a renovation are about boundaries, not amounts. Settle which of the following sit inside the lighting package, then write the answer next to the number.
- Inside: the fixtures, and the drivers and control gear supplied with them.
- Inside: integrated charging modules and any fixture-mounted interface.
- Inside: spares, replacement units and project-specific labelling or packing.
- Outside: freight, duty and customs handling, normally a logistics line.
- Outside: mains wiring, containment and installation labour, which belong to the M&E package.
- Outside on most projects: the mock-up room, often funded separately.
Two lines disappear between the boxes. The mock-up is assumed to be free because it is called a sample, when it is a room's worth of fitted luminaires. Spares are assumed to be included until somebody asks about year three.
The allowances renovation teams forget
A refurbishment carries risks a new build does not.
- Spares at handover. One replacement per fragile or high-wear type, plus restarting a finish batch for a small re-run.
- Breakage, damage and disposal. A modest allowance for units damaged in storage or during installation, plus removing the old fittings.
- Punch-list replacements. Units meeting the specification but rejected on site for colour, grain or weave variation.
- Re-access labour. Replacing a fitting after the ceiling is closed costs far more than replacing it before.
- The documentation set. Material dossiers, spare-parts schedules and installation sheets: cheap to specify, expensive to reconstruct.
Individually none of these is large. Together they decide whether the budget closes or needs a second approval three months before handover.
Contingency: why a renovation carries more than a new build
Contingency is often copied as a percentage from a template. In a renovation it should be sized by unknowns, because the unknowns are physical: a ceiling void smaller than assumed, an existing wiring class the fittings are not built for, a fixing point that cannot take the weight, a finish that cannot be matched.
Three questions keep it honest. How many rooms have been opened up and measured? How much of the existing electrical installation has been surveyed? Which specification lines are still intentions?
A lighting budget is not judged by how low it starts. It is judged by whether its assumptions are still true on the day the last phase is released.
When an assumption changes, re-baseline at the point of evidence rather than the point of pressure. Sample approval is the natural gate: after it, material, finish and function are fixed.
Keeping the budget honest through tender
A budget survives tender only if the tender runs against the same frame that produced it.
- Issue the assumption list with the budget, so returns can be tested against the same counts and materials.
- Ask for a like-for-like return, and treat a materially lower figure as a question rather than a saving.
- Fix the change-control clause before the order, so a revision has a defined route and cost consequence.
- Keep the release schedule as its own line, so a phased programme is not compared with a single sealed drop.
- Re-baseline at sample approval and at each phase release, rather than at delivery.
One boundary is worth stating. This is about how the allowance is built and defended, not the mechanics of a revision once production starts; change orders after the purchase order follow a different approval chain, and mixing the two is how a controlled budget becomes an uncontrolled one.
FAQ
How do you budget lighting for a renovation before the drawings are complete?
Build it from cost drivers rather than unit rates: fixture mix per room type, material and finish route, customisation content, control and charging, and the release schedule. Attach the assumption list so each driver can be revised as rooms are measured.
Should a lighting budget be priced per key or per fixture?
Per key suits feasibility and scheme comparison; per fixture becomes useful once room types are measured. Most renovations end up with both.
Does a bespoke fixture always cost more than a catalogue one?
Not always by much, but it carries a different cost structure. A bespoke fitting adds drawing, sampling and finish setup work; a catalogue item spreads that setup across many projects.
Who owns freight, duty and installation in the lighting line?
Usually nobody until it is written down. Freight and duty sit in a logistics line, mains wiring and installation labour in the M&E package, and the fixtures in the lighting package.
How much contingency belongs in a lighting budget?
Size it by unknowns rather than a copied percentage: how many rooms have been measured, how much of the electrical installation has been surveyed, and how many specification lines are still intentions.
The takeaway
A renovation lighting budget is an allowance for a scope that is still moving, so build it from cost drivers and issue it with its assumptions attached. The drivers that move the number most are fixture mix, material and finish route, customisation content, control and charging hardware, and the release schedule. Most of the pain sits in the lines nobody claimed: spares, mock-up, punch-list replacements and re-access labour.
Zerouno Lighting (ZeroUNO) manufactures hospitality decorative lighting in Zhongshan, China, and has built project and custom fixtures since 2013. Because a bespoke fitting's cost is decided at the sample stage, projects start from a one-piece sample that fixes material, finish and function before the order. Learn more at zerounolighting.com.
