One of the most common questions homeowners ask is: “How much does it cost to plaster a room?”
The honest answer is — it depends on the room size, wall condition, and the type of plastering needed. In this guide, we’ll break down realistic UK prices and explain what affects the final cost.
Average Cost to Plaster a Room (UK)
For a standard-sized room, most homeowners can expect to pay:
- £400 – £550 for a full room skim
- Around £490 is a common average price
This usually includes:
- All materials
- Preparation work
- Skimming walls (and ceiling if required)
- Labour
- A smooth finish ready for decorating
Prices can be higher or lower depending on the condition of the walls.
What Affects the Cost of Plastering a Room?
1. Size of the Room
Larger rooms cost more because:
- More materials are needed
- More labour time is required
A small bedroom will cost less than a large living room or open-plan space.
2. Condition of the Walls
Wall condition makes a big difference.
- Good condition walls: Simple skim — lower cost
- Cracked or damaged walls: Extra preparation needed
- Loose plaster or old mortar: May need bonding or plasterboarding
The worse the condition, the more prep work is required.
3. Ceiling Included or Not
Plastering a ceiling adds to the price, especially if:
- It’s damaged
- It has Artex
- It needs overboarding
Ceilings take longer and require more materials.
4. Artex Ceilings
If the room has an Artex ceiling, options include:
- Skimming over it
- Overboarding and skimming
Overboarding costs more but gives the best long-term result.
5. Plasterboarding vs Skimming
Sometimes walls or ceilings are too poor to skim.
In these cases:
- Plasterboarding + skimming may be required
- This increases the price but ensures a solid, long-lasting finish
Typical Room Plastering Price Examples
Here are realistic examples:
- Small bedroom (walls only): £350 – £450
- Average bedroom (walls & ceiling): £450 – £550
- Large living room: £550 – £700
- Room with Artex ceiling: £500 – £750
- Room needing plasterboarding: £600 – £900
These are guide prices — an on-site inspection or photos give the most accurate quote.
Does the Price Include Materials?
In most professional plastering quotes, yes.
A proper quote should include:
- Plaster
- Bonding or prep materials
- Beads
- Labour
- Clean-up
Always confirm this when getting a quote.
Is It Cheaper to Skim or Replaster?
- Skimming is cheaper when walls are sound
- Replastering or plasterboarding costs more but is sometimes necessary
A professional plasterer should advise honestly on the best option — not just the cheapest.
How Long Does It Take to Plaster a Room?
Most rooms take:
- 1–2 days to complete
Drying time is usually:
- 24–48 hours before painting
(Depending on ventilation and temperature.)
Is It Worth Paying for a Professional Plasterer?
Yes — plastering is one of the most visible finishes in your home.
A professional plasterer provides:
- Smooth, flat walls
- Long-lasting results
- Less mess
- Correct preparation
Poor plastering is hard to hide and often costs more to fix later.
How to Get an Accurate Plastering Quote
To get the best price:
- Measure the room
- Take photos of walls and ceilings
- Mention any cracks, damp, or Artex
Many plasterers can give a rough quote from photos, followed by a confirmed price after inspection.
