LED Downlights & Spotlights Installation Costs UK — What an Electrician Should Charge in 2026

Cost Per Downlight — Supplied and Fitted

The headline figure most customers want is the price per downlight. For a single LED downlight installed in an existing ceiling, expect to charge £40–£90 each supplied and fitted, depending heavily on access. That range assumes a straightforward fire-rated GU10 or integrated fitting spurred off an existing lighting circuit with a clear loft above. The more fittings you install in one visit, the lower the per-unit price you can offer, because your setup, testing and certification time is spread across the whole job.

Where there's no loft access — a flat above, a plastered ceiling on the top floor, or a vaulted ceiling — the price per fitting climbs because every hole has to be fed and the cable run managed blind from below. Don't quote a flat per-fitting rate sight unseen; the access situation can double your labour.

• Single downlight, good loft access: £40–£60 each
• Single downlight, no access / awkward ceiling: £60–£90 each
• Multiple fittings in one visit: rate drops toward the lower end

Replacing Old Halogen Downlights with LED

Swapping like-for-like — pulling out tired halogen or first-generation LED fittings and dropping in modern integrated LEDs — is quicker because the holes and wiring already exist. Charge £25–£60 each for a straight replacement, again with the lower end applying when you're doing a full room or house in one go.

Be careful with two things. First, old MR16 fittings run on 12V transformers that the customer will want removed — factor that in. Second, if the existing holes don't match the cut-out size of the new fitting, you're into plaster making-good, which changes the job entirely. Always check cut-out diameters before you quote a simple swap.

A Full Room of Six Downlights

A typical kitchen or living room of six downlights is the bread-and-butter job. Supplied and fitted into an existing ceiling with reasonable access, this lands at £300–£600. A like-for-like replacement of six existing fittings is cheaper at roughly £200–£400. If the room currently has a single pendant and you're creating a new layout — adding fittings, running fresh cable and possibly a new switch drop — you're at the top of that range or above once making-good is included.

Whole-House and Multi-Room Jobs

Doing a whole house — kitchen, hallway, landing, bedrooms and bathroom — typically falls between £800 and £2,500+. The spread is wide because it depends on the number of fittings (20–40 in an average home), whether you're replacing or installing fresh, how many rooms need new circuits or switch positions, and the amount of plaster making-good. Price whole-house jobs by the day plus materials rather than purely per fitting — it protects you when access turns out to be worse than expected.

Day Rates and How to Build Your Price

A self-employed electrician's day rate in 2026 is typically £200–£350 per day, higher in London and the South East, lower in parts of the North and Wales. Most downlight jobs are priced as a fixed quote rather than day work, but the day rate is the number you should be working back from to make sure a per-fitting price actually pays.

As a rough rule, a competent electrician with a good loft above can install and certify 8–12 new downlights in a day, or replace 15–20 like-for-like. Map your day rate against that throughput, add materials and a margin, and you'll see whether your per-fitting price stacks up. If you're quoting £40 a fitting and only managing six a day because access is poor, you're working for less than your day rate.

First-Fix vs Retrofit — Why It Matters for Price

The single biggest driver of cost is whether you're wiring before or after the ceiling goes up. On a new build or full refurbishment, downlights are part of the first fix: the ceiling is open, joists are exposed, and you run cable freely before the plasterboard and plaster go on. This is fast and cheap per fitting because there's no fishing cable and no making-good.

Retrofitting into a finished, plastered ceiling is a different job. Every fitting needs a clean cut-out, cable has to be fed across joists from above or fished from below, and any chasing or holes you make have to be filled and decorated. Retrofit can cost two to three times the per-fitting first-fix price for the same number of lights. When a customer compares your retrofit quote to a builder's first-fix figure from their last project, explain the difference clearly — it's the most common source of price pushback.

What Drives the Price Up

Two downlight jobs with the same number of fittings can differ by hundreds of pounds. These are the factors that move your quote:

• Fire-rated vs non-fire-rated fittings: Fire-rated downlights restore the fire integrity of a ceiling that a hole would otherwise breach. They cost more per fitting (£8–£20 each vs £4–£10) and are effectively mandatory in most domestic ceilings between floors. Quote fire-rated as standard.
• Integrated LED vs GU10 lamp holders: Integrated fittings are sealed units with a fixed lifespan; GU10 holders let the customer replace the lamp. Integrated fittings often cost more but install faster. Make sure the customer understands they can't swap a bulb in an integrated unit.
• Dimmable + compatible dimmer: LED dimming only works with a trailing-edge dimmer matched to the fittings. Supplying and fitting a compatible dimmer adds £30–£70 per switch, and incompatible combinations cause flicker that you'll be called back to fix for free if you didn't price it in.
• IP-rated fittings for bathrooms: Bathroom and wet-zone fittings must be IP-rated to the correct zone (IP65 in zones 1 and 2). They cost more and the wiring must respect the zone rules, so bathrooms carry a premium.
• Loft access: Boards up, insulation pulled back and re-laid, and crawling in a low loft all add time. No access at all is the most expensive scenario.
• Joist positions and notching: Fittings rarely land neatly between joists. Notching joists must follow the permitted zones, and a fitting that clashes with a joist may have to move — which means a second hole and more making-good.
• New circuit vs spurring off existing: Adding lights to an existing lighting circuit is quick. Running a new circuit back to the consumer unit, or upgrading an overloaded circuit, adds significant labour and materials.
• Plaster making-good: Holes, chases and damaged ceiling have to be filled and often need a decorator afterwards. Decide who's doing it and price it.
• High ceilings and scaffolding: Stairwells, double-height halls and tall rooms may need a tower or access platform. That cost should be a separate line.

Part P, Certification and Fire-Rated Fittings

Installing downlights is electrical work, and in England and Wales most of it is covered by Part P of the Building Regulations. Adding new lighting points or a new circuit, and any electrical work in a bathroom or kitchen wet zone, is generally notifiable. That means the work must either be carried out by an electrician registered with a competent person scheme (NICEIC, NAPIT, ELECSA and similar) who can self-certify, or be notified to building control.

On completion you must issue the correct certificate. A like-for-like alteration on an existing circuit is usually covered by a Minor Electrical Installation Works Certificate, while a new circuit requires a full Electrical Installation Certificate. Both confirm the work was tested and meets BS 7671. Customers increasingly ask for this paperwork because conveyancers want it at sale — and your certification time is a real cost that belongs in every quote.

Fire-rated downlights are not optional extras. Cutting holes in a ceiling that separates floors removes part of its fire resistance, and fire-rated fittings are designed to restore that integrity under the Building Regulations. Fitting non-fire-rated downlights in such a ceiling is a defect that will show up on any future inspection. Always specify and price fire-rated fittings for ceilings with a habitable space or loft above.

Worked Example — Pricing a Typical Kitchen

A customer wants eight new fire-rated LED downlights installed in a kitchen ceiling, replacing a single pendant. There's a boarded loft above with reasonable access. They want the lights dimmable on a new dimmer switch, fed by spurring off the existing lighting circuit. Here's how the quote builds:

• Labour — one day for cutting, cabling, fitting and testing: £280
• 8 × fire-rated integrated LED downlights at £14 each: £112
• Trailing-edge LED dimmer switch supplied and fitted: £45
• Cable, connectors, clips and sundries: £35
• Minor Works Certificate and testing time: £40
• Plaster making-good at the old pendant position: £30

That totals around £542 before margin. Add your markup on materials and a sensible profit on labour and you'd quote this in the region of £575–£650. If the loft turned out to be inaccessible, or the customer wanted a separate new circuit, that figure would rise toward £750–£850.

Quoting Tips — How to Stop Underpricing

Downlights are the classic job electricians lose money on because the customer's mental model is "you're just popping a few bulbs in". Protect yourself:

• Always survey the ceiling first. Get into the loft or look at the ceiling type before you quote. Access is everything, and you can't see it from a phone call.
• Price the certification. Testing and paperwork take real time. Build it into every quote rather than treating it as free.
• Separate making-good. Make clear whether plaster repair and decoration are included or the customer's responsibility. Vague wording here causes disputes.
• Quote fire-rated and IP-rated as standard. Don't let a cheaper competitor's non-compliant fittings drag your price down — explain why yours are correct.
• Add a contingency for joist clashes. Fittings move, holes multiply. A small allowance keeps you whole when the layout fights back.
• Charge a fair minimum. For a one or two fitting visit, a per-fitting rate won't cover your travel and setup. Set a sensible call-out minimum.

A clear, itemised quote that separates labour, fittings, dimmer, certification and making-good wins more work than a single round number — and it stops the customer assuming any of it was free.
