If you're planning a renovation, there's a good chance lighting isn't the first thing on your budget spreadsheet, and that's exactly why it tends to blow the budget out when it finally gets addressed. Cabinetry, flooring, and tiling usually get quoted early and locked in. Lighting often gets left until the electrician asks, "so what fittings are you using?" partway through the job, at which point it's a rushed decision instead of a planned one.
This guide breaks down realistic lighting costs by room, the line items people consistently underestimate, and a worked example for a typical Australian home renovation — so you can budget for it properly from the start, not scramble for it at the end.
Why Lighting Gets Underestimated So Often
Two reasons come up again and again:
It's priced per-item, not per-room. A single pendant light might look affordable on its own. But a full home renovation isn't buying one pendant — it's buying downlights for every room, a few statement pieces, outdoor lighting, and often ceiling fans too. The per-item cost feels small; the total doesn't.
Downlights are treated as an afterthought. Most renovators budget for the "feature" lighting — the pendant over the dining table, the chandelier in the entryway — but forget that a single living room can need 8–12 downlights on its own. Multiply that across a whole house and it adds up fast, even though each individual downlight is cheap.
Average Lighting Costs by Room (Australia, 2026)
These are realistic per-room ranges based on standard fixture counts and mid-range fittings — not the cheapest possible option, not designer/luxury pricing either.
| Room | Typical Fixtures Needed | Estimated Cost Range |
|---|---|---|
| Kitchen | 6–10 downlights, 1–2 pendants over island/bench | $250 – $1000 |
| Living Room | 8–12 downlights, 1 feature pendant or floor lamp | $300 – $700 |
| Main Bedroom | 4–6 downlights, 1–2 bedside lamps | $150 – $350 |
| Bathroom | 4–6 downlights (IP-rated), 1 vanity wall light | $150 – $400 |
| Hallway/Entryway | 3–5 downlights, 1 statement pendant (optional) | $100 – $350 |
| Outdoor/Alfresco | 4–8 wall lights or bollards | $200 – $500 |
A typical 3–4 bedroom full home renovation, lighting every main room, usually lands somewhere between $1,500 and $3,500 — before any high-end statement pieces are factored in.
Downlights: The Line Item Everyone Underestimates
This is the one worth budgeting for deliberately, because it's rarely a single purchase — it's dozens of small ones that add up.
A general rule of thumb electricians use roughly one downlight per 2–3 square metres of ceiling space, depending on ceiling height and how bright you want the room. A modest 20sqm living area can easily need 8–10 downlights on its own.
At a typical $12–$45 per downlight depending on style (basic tri-colour vs premium adjustable/gimble), a full home reno's downlight total alone often sits between $300 and $900 — before pendants, wall lights, or anything else is added.
This is exactly why bulk downlight purchasing (or a promotion that includes them) is worth paying attention to if you're renovating — it's the one category where quantity, not individual price, drives the total.
Statement Pieces: When It's Worth Spending More
Downlights and basic fixtures are functional — statement pieces (a feature pendant, a chandelier, a sculptural floor lamp) are where a room actually gets its character. A few guidelines:
- One statement piece per "view line," not per room. The dining table, the entryway, maybe the living room — not every single space needs a hero fixture.
- Spend where people actually look up. Over a dining table or kitchen island is high visibility; a hallway ceiling usually isn't.
- Mid-range statement pieces typically run $150–$260, with premium/oversized pieces going higher.
A Realistic Full-Home Lighting Budget Example
Here's a worked example for a common renovation scope — kitchen, living room, two bedrooms, one bathroom, and outdoor entry lighting:
| Category | Estimated Cost |
|---|---|
| Downlights (approx. 30 total across the home) | $500 |
| Kitchen pendant/island lighting | $250 |
| Living room feature pendant or floor lamp | $220 |
| Bedroom bedside lamps (x2 rooms) | $200 |
| Bathroom vanity light | $180 |
| Outdoor wall lights (x4) | $500 |
| Estimated total | $1,850 |
Scale this up for larger homes, more bathrooms, or higher-end statement pieces, and it's common to see full-home lighting budgets land closer to $2,500–$4,000.
Tips to Stretch Your Lighting Budget Further
- Buy downlights in bulk from one supplier rather than piecing them together — per-unit pricing usually drops, and you avoid mismatched colour temperatures across rooms.
- Choose RCM-approved fittings. It's a compliance requirement in Australia, but it also protects you from cheap imports that fail early and need replacing.
- Time bigger purchases around genuine sales, not manufactured "limited time" discounts. If you're already planning to spend $1,500–$3,500 on lighting for a renovation, a promotion tied to that natural spend level is worth checking before you buy piecemeal.
If you're renovating this September specifically, it's worth knowing In2Lighting is running a Renovation Special through September 30th: spend $2,000 or more on lighting and choose either 20 free downlights (added automatically, no code needed) or any single item free up to $240. Given the budget ranges above, a full-home lighting spend often lands right around that $2,000 mark anyway — worth timing your purchase if you're already planning the reno for this year.

Frequently Asked Questions
How many downlights do I need per room? As a general guide, budget for one downlight per 2–3 square metres of ceiling space, adjusted for ceiling height and desired brightness. A licensed electrician can confirm exact spacing for your specific layout.
Is it worth hiring an electrician just for lighting during a renovation? Yes — in Australia, lighting installation legally requires a licensed electrician regardless of renovation scope. Budget their labour separately from the cost of the fittings themselves.
Should I choose warm white or cool white lighting for a renovation? Warm white (2700K–3000K) generally suits living areas and bedrooms; cool white (4000K+) is more common in kitchens, bathrooms, and garages where task lighting matters more than ambience. Many modern downlights now offer tri-colour/adjustable options, letting you decide room by room after installation.
Do lighting costs usually blow out during a renovation? It's common, mainly because downlights and small fittings are underestimated compared to statement pieces. Budgeting per-room using the ranges above, rather than per-fixture, helps avoid the surprise at the end.
