Changing a ceiling light is usually the same job twice over: one fitting comes down from a light point that already exists, and another goes up in its place. What decides whether you take it on is not the light. It is whether you can isolate the circuit and satisfy yourself it is dead, and whether the fitting you have chosen asks something of your ceiling that the old one did not.
Three lines on the product page answer that second half before you buy. Here they are, with what each one costs you when it goes wrong.
The short version
- Most fittings arrive without lamps, so price those on top of the fitting
- The Class line tells you whether your ceiling needs an earth
- Weight decides whether the screws in the box are the whole answer
- Projection, not diameter, is what takes your headroom
- If isolating the circuit is not something you are sure of, use a registered electrician
What actually comes in the box
A ceiling light usually arrives as the fitting, a ceiling plate, the screws the maker supplies, a connector block and the instructions. The plate is the part that goes on the ceiling, and the fitting then sits or hangs on it. One customer who put up the Novena Caroli 3 Light Semi Flush Ceiling Light Clear Cut Glass Antique Brass (£176.95, checked 9th November 2026) wrote in a review that it arrived well packaged, with the fixings and tools required and full instructions. That is what we expect from the makers we stock.
What is almost never in the box is the lamps. On most of our fittings the Details table carries a line reading Lamps included: No, and that is a real cost sitting on top of the price you just compared. The Endon Orta 6 Light Semi Flush Ceiling Light in Satin Brass (£152.95, checked 9th November 2026) takes six G9 lamps. The Caroli takes three E14 candles. Our guide to what bulbs your new light needs works through the caps and what they cost.
The Class line, and why your ceiling cares about it
Our product pages carry a Details table, and on that table is a line marked Class. It is the most useful line on the page and the easiest to skip.
- Class 1, sometimes written Class I, means the fitting relies on an earth connection. The ceiling needs one.
- Class 2, or Class II, means the fitting is double insulated and does not need an earth.
That single line decides which fittings are open to you. If the ceiling rose you are taking down has no earth conductor, a Class 2 fitting is the straightforward choice and a Class 1 fitting is a conversation with an electrician before you order, not after the parcel arrives. Of the fittings in this guide the Endon Orta is the one Class 2 piece. The rest are Class 1.
What it weighs, and what the ceiling has to hold
Weight decides whether the screws in the box are the whole answer. Of the six fittings in the table below, the Novena Caroli is the heaviest at 4.28 kg and the Interiors 1900 Dark Star the lightest at 2.26 kg. Where the plate fixes into a joist, follow the maker's instructions. Into plasterboard with nothing behind it, you need a fixing rated for the load, and the screws in the box are usually not suited to plasterboard on their own.
The other thing weight changes is the holding. A fitting of four or five kilograms wants two pairs of hands at the ceiling, one to hold and one to connect, which is worth knowing before you borrow the ladder.
Projection is the measurement that takes your headroom
Diameter decides how the fitting looks in the room. Projection decides whether anyone walks into it. Our guide to sizing a ceiling light works to 2.1 metres of clearance where people pass beneath a fitting. Measured against that, on a standard 2.4 metre ceiling, two of the six below clear it.
| Fitting | Class | Weight | Projection | Clear under a 2.4m ceiling | Price |
|---|---|---|---|---|---|
| Interiors 1900 Fargo 2 Light Tiffany Flush | Class 1 | 2.44 kg | 170mm | 2.23m | £163.95 |
| Hinkley Plantation 2 Light Flush | Class 1 | 2.5 kg | 200mm | 2.20m | £161.75 |
| Interiors 1900 Dark Star 3 Light Semi Flush | Class 1 | 2.26 kg | 315mm | 2.09m | £125.75 |
| Novena Caroli 3 Light Semi Flush | Class 1 | 4.28 kg | 380mm | 2.02m | £176.95 |
| Endon Berenice 3 Light Semi Flush | Class 1 | 2.35 kg | 410mm | 1.99m | £75.10 |
| Endon Orta 6 Light Semi Flush | Class 2 | 2.75 kg | 480mm | 1.92m | £152.95 |
Two clear 2.1 metres on that ceiling: the Interiors 1900 Fargo 2 Light Tiffany Flush Ceiling Light in Satin Black (£163.95, checked 9th November 2026) at 170mm of projection, and the Hinkley Plantation 2 Light Flush (£161.75) at 200mm. Both are flush fittings. The word semi flush is not a promise of headroom: the Orta projects 480mm. If your ceiling is 2.4 metres and the fitting hangs over a walkway rather than a sofa, that table is the whole decision.
The half the instructions understate
Getting the plate on the ceiling is often the quick half. Assembly is the slow half, and it is where the reviews go. A customer who fitted the Endon Orta wrote that the rods screw on one at a time and that it took a while, though it was worth the patience. Another, on a Tiffany flush fitting, wrote that the fixing was a bit fiddly but the light looks fine now it is up.
Neither of those is a fault. They are both worth knowing before you start. A six arm fitting is six separate pieces of assembly, glass goes on last, and a Tiffany shade is heavier and less forgiving than it looks in the photograph. Give the job an evening rather than twenty minutes and none of it is a problem.
When to get an electrician
We sell lighting, we do not wire it, so take this as a merchant's list rather than an electrician's. Get a registered electrician when:
- you are not certain you can isolate the lighting circuit and satisfy yourself it is dead
- the ceiling rose has no earth and the fitting you want is Class 1
- there is no light point where you want the light, so a new one has to be run
- the existing rose, cable or ceiling is damaged, scorched or loose
- the fitting is heavy and the ceiling is plasterboard with nothing behind it
None of that is a reason to avoid the job. It is a reason to know which job you are doing before you start.
Where the law sits, and where our opinion starts
Part P of the Building Regulations covers electrical safety in dwellings in England. The current Approved Document P is the 2013 edition, and it explains when electrical work has to be notified to building control (checked 9th November 2026). Wales, Scotland and Northern Ireland have their own building regulations. Whether a particular job needs notifying depends on the work and on the building, so the people to ask are your local building control body or a registered electrician.
That is the law, and it is not ours to interpret. Our own position is narrower and commercial. We can tell you what is in the box, what the fitting weighs, which cap it takes and whether it needs an earth, because we buy it, store it and ship it. We cannot tell you whether your ceiling is sound or your circuit is earthed, and anyone selling you a light who claims otherwise has not seen your ceiling.
Frequently asked questions
Do I need an electrician to change a ceiling light?
That depends on the work and on you, not on the light. Swapping a fitting on a light point that already exists is a different job from running a new one. Part P of the Building Regulations covers electrical safety in homes in England, and the Approved Document explains when work must be notified. If you are not confident isolating the circuit and satisfying yourself it is dead, use a registered electrician.
Can I change a ceiling light myself?
On a like for like swap, it can be a DIY job. What decides it is whether you can isolate the circuit at the consumer unit, prove it is dead with a voltage tester, and reconnect the new fitting to the maker's instructions. Check the Class line before you order. A Class 1 fitting relies on an earth at the ceiling, and an older lighting circuit does not always have one.
Does a new ceiling light come with bulbs?
Usually not. On most of our fittings the Details table carries a line reading Lamps included: No, which means the lamps are a separate cost on top of the fitting. Check the cap and the maximum wattage on the same table before you buy them, because the fitting sets both. Our guide to what bulbs your new light needs works through the caps.
What does Class 1 mean on a light fitting?
Class 1, sometimes written Class I, means the fitting relies on an earth connection for safety, so the ceiling needs an earth. Class 2, or Class II, means it is double insulated and does not need one. Both appear on the Details table of the product page. If your ceiling rose has no earth, that one line decides which fittings are open to you.
How do I replace a ceiling rose with a new light fitting?
The new fitting brings its own ceiling plate, which takes the place of the old rose. Isolate the circuit, take the old rose down, then check what the fitting asks of the ceiling: its weight, whether it needs an earth, and whether the maker's screws will hold where you are fixing them. Plasterboard with no joist behind it needs a fixing rated for the weight. If the old rose has several cables joined in it, a loop-in rose, the new fitting may not have terminals for them all, and that is a job for a registered electrician.
