Plasterboard Ceilings London: Cost, Process and What to Ask
A plasterboard ceiling in a typical London bedroom costs around £350 to £600 fitted and skimmed, rising to £800 to £1,500 or more for a full replacement of an old lath and plaster ceiling, especially where joists need attention or fire-rated board is required between flats. Standard sheets are 2400mm by 1200mm in 9.5mm, 12.5mm or 15mm thickness, fixed to joists at 400mm or 600mm centres, then skimmed or taped and jointed. Most domestic jobs take one to three days on site, plus drying time before you can paint.

What a plasterboard ceiling job actually involves
Fitting a plasterboard ceiling is not just screwing sheets up and moving on. It is measuring and cutting boards to land joins on joists, lifting sheets that weigh close to 9 to 10kg per square metre at 12.5mm thickness, screwing at set centres so the board does not sag between fixings, then finishing the joints and the whole surface so it reads as one flat plane rather than a grid of visible boards.
In a lot of London properties, especially conversions and Victorian terraces, the job also involves dealing with what is already up there. Original lath and plaster ceilings, old Artex, uneven joists that have moved over a century, and sometimes pipework or cabling that was never meant to be exposed. That is why two ceilings of the same size can have very different quotes.
Plasterboard ceilings London: typical costs
Prices vary by borough, access, and whether you are boarding a fresh ceiling or stripping out an old one first. The figures below are typical ranges for 2026 and should be confirmed against a written quote for your specific ceiling.
| Job | Typical cost | Typical timeframe |
|---|---|---|
| Small patch repair (crack or hole up to 0.5m²) | £80 to £200 | Half a day |
| Bedroom ceiling, board and skim (10 to 12m²) | £350 to £600 | 1 to 2 days plus drying |
| Living room ceiling, board and skim (15 to 20m²) | £500 to £900 | 2 to 3 days plus drying |
| Full replacement inc. stripping old lath and plaster | £800 to £1,500+ | 3 to 5 days |
| Artex removal or skim-over, per m² | +£15 to £25 on top of standard rate | Adds 1 day |
| Fire-rated board upgrade (between flats), per m² | +£5 to £10 | No extra time usually |
Most tradespeople price by the square metre for larger areas, typically £20 to £35 fitted and finished, or by a day rate of roughly £180 to £280 for a plasterer or experienced handyman working alone. Get at least two quotes in writing, and ask whether the price includes making good around light fittings, skirting or coving, because that is a common add-on that turns up on the invoice later.
Repair vs full replacement
A repair makes sense if the damage is localised: a water stain from a one-off leak, a crack from settlement, a small hole from a fitting that came out. A patch of plasterboard is cut in, screwed to the surrounding joists or noggins, and skimmed to blend with the existing ceiling.
Full replacement is the right call when the ceiling is sagging across a wide area, when there are multiple cracks radiating from different points, or when you are taking the opportunity to add insulation, run new cabling, or upgrade to fire-rated board because you are in a converted flat. Once you are removing more than about a third of a ceiling, most tradespeople will recommend doing the whole thing, because matching a new patch to old, uneven lath and plaster rarely looks right once painted.
Signs your ceiling needs attention
Bounce test aside, there are a few tells that come up again and again in London's older housing stock:
- Visible sag or a bellied appearance, particularly in the centre of the room, which usually means the original lath and plaster has lost its key to the joists.
- Brown or yellow staining, which points to a current or historic leak above, and needs the source fixed before any plasterwork is redone.
- Fine cracking in a spider pattern across the whole ceiling, common where a house has settled or where central heating was added decades after the original plaster went up.
- A hollow, papery sound when you tap it, which suggests the plaster has separated from the laths behind it even if it looks fine.
If you spot sagging or staining and you are not sure whether it is cosmetic or structural, it is worth getting someone out to look rather than guessing. Our emergency handyman London team gets called to genuine ceiling collapses a few times a year, almost always in properties where a small sag was left for months because it "wasn't that bad."
Board thicknesses and when each is used
| Thickness | Common use | Notes |
|---|---|---|
| 9.5mm | Curved work, some overboarding | Lighter but flexes more, needs closer fixing centres |
| 12.5mm | Standard domestic ceilings | Most common choice for new ceilings at 400 to 600mm joist centres |
| 15mm (fireline/fire board) | Between flats, escape routes, some loft conversions | Required in many conversion properties for fire compartmentation, confirm with building control |
| Acoustic/soundboard | Flats above noisy rooms, party walls | Denser board, often paired with resilient bars for sound reduction |
If you own or manage a converted period property, this matters more than it sounds. Fire and sound requirements between flats are governed by Building Regulations Part B and Part E, and a ceiling that looks identical to standard board can be the wrong specification entirely for a converted terrace.
The installation process, step by step
- Clear and protect the room. Furniture moved or covered, dust sheets down, existing light fittings capped off safely.
- Remove old material if needed. Lath and plaster stripped back to the joists, or old boards taken down. This stage generates a genuine amount of dust and rubble that needs bagging and removing.
- Check and prepare the joists. Any rot, damage or excessive gaps get sorted before anything new goes up, along with adding noggins where board edges need extra support.
- Board the ceiling. Sheets go up with a plasterboard lift or a second person holding while the fixer screws at the correct centres, staggering joints so they do not all line up on one joist.
- Tape and finish the joints. Either a full skim coat of multi-finish plaster over the whole ceiling, or a tape and joint finish where only the joins and screw heads are filled and sanded.
- Dry and mist coat. New plaster needs to dry before it is painted, usually 5 to 7 days depending on the season and ventilation, then a diluted mist coat of emulsion goes on before the full colour.
If you are also dealing with skirting, coving or fitting anything to the finished ceiling, it is worth planning that sequence before work starts rather than after. Our plastering services in London page covers the skim and finish stage in more detail if that is the part you are trying to price separately.
Building regulations and fire safety
For a straightforward like for like ceiling replacement in a single-occupancy house, you generally will not need planning permission or building control sign-off. Where regulations start to matter is converted flats, houses in multiple occupation, and anywhere the ceiling forms part of a fire separation between units. In those cases, fire-rated plasterboard and correct fixing detail are not optional extras, they are required, and building control or your local authority can confirm what applies to your specific building. If you are unsure, it is worth checking before work starts rather than after the ceiling is closed up.
Artex ceilings and asbestos
Textured Artex coatings were fitted widely across UK homes through the 1970s, 80s and into the 90s, and some products made before the wider UK asbestos ban in 1999 contained small amounts of asbestos in the coating. This does not mean every Artex ceiling in London is a hazard: undisturbed and in good condition, it generally poses very low risk. The risk comes from sanding, drilling or ripping it out without checking first, which can release fibres into the air.
If your property has an original Artex ceiling and you are planning to remove it, skim over it, or drill into it extensively, get it tested or have a specialist assess it before work begins. Skimming directly over intact Artex without disturbing it is usually the lower-risk, lower-cost option, and a competent tradesperson should raise this with you before quoting rather than after starting.
The costliest mistake we see: homeowners in period London properties assuming an old textured ceiling is "just Artex" and having it sanded back or ripped out without any testing. If it turns out to contain asbestos, work stops immediately, the room needs professional decontamination, and costs can run into thousands rather than hundreds. A test before work starts typically costs a fraction of that and settles the question properly.
Related work worth planning together
Ceiling work often overlaps with other jobs on the same visit. If you are already having a plasterer or handyman in for a ceiling, it is worth mentioning any other small jobs stacking up around the house, from loose skirting to a shelf that needs putting up, since our small jobs and odd job handyman service can often bundle these into the same visit and save you a second call-out fee.
FAQ
How much does a plasterboard ceiling cost in London?
A standard bedroom ceiling, boarded and skimmed, typically costs £350 to £600 in London. A larger living room ceiling runs £500 to £900, and a full replacement including stripping out an old lath and plaster ceiling can reach £800 to £1,500 or more. Prices depend on ceiling size, access, and whether existing material needs removing first, so always confirm with a written local quote.
How long does it take to plasterboard a ceiling?
Boarding and skimming a typical domestic ceiling takes one to three days of hands-on work, depending on size and condition. On top of that, the new plaster needs roughly 5 to 7 days to dry fully before painting, so the whole job from start to finish is usually a week to ten days if you include drying time.
Can I plasterboard over an existing ceiling?
Yes, overboarding an existing ceiling is common and avoids the mess of stripping the old surface out. It works well where the existing ceiling is sound but tired-looking, though it does lower the ceiling height slightly and adds weight, so it is not suitable if the existing ceiling is already sagging or unsound.
Do I need permission to replace a ceiling?
For a like for like replacement in a standard house, you generally do not need planning permission or building control approval. If your property is a converted flat, an HMO, or the ceiling forms part of a fire separation between units, building regulations may apply, particularly around fire-rated board. Confirm with your local building control team if you are unsure.
How long before I can paint a new plasterboard ceiling?
New plaster needs to dry out fully before painting, which usually takes 5 to 7 days depending on the season, room temperature and ventilation. Painting too early traps moisture behind the paint film and can cause bubbling or blistering later. A diluted mist coat goes on first, followed by the full emulsion once that has dried.
What thickness plasterboard should I use for a ceiling?
12.5mm is the standard thickness for most domestic ceilings at normal joist spacing. 9.5mm is lighter but flexes more and needs tighter fixing centres. 15mm fire-rated board is used where fire separation matters, such as between flats in a converted property, and should be specified based on what building regulations require for your building type.
Is my old Artex ceiling dangerous?
An intact, undisturbed Artex ceiling poses very low risk. Some Artex products made before the UK's 1999 asbestos ban contained small amounts of asbestos, and the danger comes from disturbing it through sanding, drilling or removal without testing first. If you plan to remove or heavily disturb an old Artex ceiling, get it tested before work starts.
Can a handyman fit plasterboard ceilings or do I need a plasterer?
Both can do it, and the right choice depends on the finish you want. A plasterer typically handles a full skim finish for a smooth, professional result, while an experienced handyman can often manage boarding, small repairs, and tape and joint finishes. For a full ceiling with a skim finish, most people book a plasterer or a handyman working alongside one for the finishing coat.
