How Much Does It Cost to Plaster a Room in the UK? (2026 Prices)

Fresh plaster transforms a room like nothing else — but plastering is skilled work with skilled-work prices. Here’s how much it costs to plaster a room in the UK, what affects the price, and when you can DIY.

Typical prices

• Skim over existing plaster (per room): £300–£600 for a small bedroom; £500–£900 for a large living room
• Per square metre (skim): £15–£25/sqm in most of the UK; £25–£40/sqm in London
• Full re-plaster (hack off and re-do): £30–£50/sqm — roughly double skimming
• Ceiling only: £200–£400 for a standard room (ceilings cost more per sqm — it’s harder work)
• Whole house (3-bed): £4,000–£8,000 for full re-plaster

What affects the price?

• Condition of walls: sound walls needing a skim are cheapest; blown plaster that must come off doubles the job
• Room size and shape: alcoves, bay windows and high ceilings add time
• Access: clearing the room yourself saves money — plasterers charge for moving your stuff
• Location: London and the South East run 30–50% higher
• Timing: plasterers are busiest in spring/summer; winter bookings can be keener

Skim vs full re-plaster

• Skimming (2–3mm of finishing plaster over sound existing plaster): cheaper, faster (1–2 days per room), less mess. Right for 80% of rooms.
• Full re-plaster (remove old plaster, apply base coat + finish): needed when plaster is blown (hollow-sounding), badly cracked, or contaminated. Much messier — the room becomes a building site.

Tap the walls: hollow or drummy sounds mean blown plaster that needs coming off. Solid with hairline cracks just needs skimming.

Getting quotes

1. Get 3 quotes — plastering prices vary wildly between tradesmen.
2. Ask whether the price includes materials (it usually does) and making good afterwards.
3. Check recent work — plastering quality is immediately visible; ask to see a finished room.
4. Look for reviews on Checkatrade or local trade groups.
5. Agree the scope: exactly which walls/ceiling, who’s clearing the room, who’s cleaning up.

Can you DIY plastering?

Honest answer: small patches, yes; whole rooms, probably not — at least not well. Plastering is genuinely skilled: the timing, trowel work and finish take practice. What DIYers can do:

• Patch repairs with ready-mixed filler or one-coat plaster (£10–£20)
• Easifill for taping dry-lined walls — much more forgiving than wet plaster
• Practice on a garage or utility wall before attempting a living room

A bad DIY plaster job costs more to fix (hack off and redo) than hiring a pro in the first place. Know your limits — this is the trade where they show.

After plastering: the critical bit

• Let it dry fully: 1–2 weeks (longer in winter). It goes from dark to uniform pale pink when dry.
• Mist coat: first paint coat must be watered-down emulsion (roughly 70% paint, 30% water) — painting full-strength emulsion on fresh plaster causes peeling.
• Don’t rush: wallpapering or tiling before plaster is fully dry traps moisture.
• Ventilate the room gently — heat it mildly, don’t blast it (rapid drying causes cracking).

The bottom line

Budget £400–£700 for skimming a standard bedroom (more in London), get three quotes, and clear the room yourself to keep costs down. Skimming over sound walls covers most needs — reserve full re-plastering for genuinely failed plaster. And whatever you do, mist-coat before painting: it’s a 20-minute job that prevents the most common plastering disaster.

Plaster vs dry lining: the modern alternative

For badly damaged walls, there’s an alternative to wet plaster: dry lining — fixing plasterboard to the walls (dot-and-dab adhesive or battens) then skimming or taping the joints. Cost: £25–£40/sqm — similar to full re-plastering, but faster (no drying time for base coats), cleaner, and easier to get perfectly flat. It’s also the route for insulated plasterboard (thermal upgrade + new surface in one job — £35–£55/sqm).

When dry lining wins: very uneven walls (dot-and-dab bridges anything), wanting insulation (insulated boards), speed matters (rooms usable in days not weeks). When wet plaster wins: period properties (breathability matters in old buildings — gypsum plaster is less breathable than lime, and dry lining can trap moisture), curved/irregular surfaces, and purists who want the traditional solid feel. For standard modern rooms needing a re-skim, wet skim remains cheapest and best.

Plastering FAQs

How do I find a good plasterer? Recommendations first (ask anyone who’s had work done recently), then Checkatrade with photos of finished work. See a finished room if possible — plastering quality is instantly visible in raking light. Good plasterers are booked 4–8 weeks ahead; immediate availability for a large job is a warning sign.

Should I supply materials? No — plasterers prefer their own materials (they know the brands and quantities) and the cost difference is minimal. What you should do: clear the room completely and protect floors in access routes — you’re paying for plastering, not furniture moving.
