Is my plastering quote fair? A UK price-sense check
How to judge a UK plastering quote: typical price tiers, the skim-vs-replaster gap, the items most often missing (prep, drying time, making good), and the red flags that mean the quote needs a second look before you sign.
Plastering quotes are hard to judge because the same room can be priced two very different ways: a thin skim over the existing surface, or a full strip-and-replaster back to brick. Two quotes for "plastering the lounge" can be £400 apart and both honest, because they are doing different jobs. This guide is a checklist you can run against your own quote, in plain language, in the order it usually matters.
For ranges and material definitions, start with the plastering cost guide. For the general method, see how to tell if a quote is too high.
Typical price, so you have a benchmark#
In 2026, a UK plastering job typically costs:
- Skim over existing sound wall: £15–£25 per m²
- Full replaster (backing plus skim): £30–£40 per m²
- Over old or uneven walls (extra prep): £35–£55 per m²
- Per small room (full replaster): £450–£650
- Per medium room (full replaster): £600–£850
- Per large room (full replaster): £850–£1,150
- Per ceiling (wet plaster): £240–£750 by size
Day rates run £180–£250 in the North, £200–£275 in the Midlands, and £250–£350+ in London and the South-East. If your quote is well outside these bands without a clear reason (specialist lime plaster, listed property, full re-skim of an entire house), that is the first thing to ask about.
The skim-vs-replaster gap#
The single biggest reason plastering quotes vary is whether you are paying for a skim or a replaster. They are different jobs:
- Skim only. A 2–3mm finishing coat over existing sound plasterboard or solid plaster. Right when the wall is flat, dry, and secure and you just need a smooth finish for paint.
- Full replaster. Stripping back to brick or stud, applying a backing coat (browning, bonding, or hardwall), then skimming over the top. Right when the existing plaster is blown, damp, cracked, or coming away.
A skim costs £15–£25 per m². A replaster costs £30–£40 per m². The "cheapest" quote is often a skim against a replaster on the same room. Both are reasonable for the work they describe. Neither is reasonable for the wrong scope: skim over failing plaster blows within months, and a replaster of a sound wall is overspend.
Ask each quote which scope it is pricing before you compare.
What a fair plastering quote should itemise#
A reasonable quote breaks the price into clear lines. The minimum you should see, with a price or quantity next to each:
- Coat system: skim only, or backing plus skim, named explicitly.
- Area or scope: m² of wall, m² of ceiling, or per-room with sizes.
- Prep: removing failing plaster, sheeting the floor, masking sockets and skirting, disposal of waste.
- Substrate: type of backing coat (browning, bonding, hardwall) and what it is being applied to.
- Beads and stops at corners and openings.
- Finish coat: multi-finish, finish, or specialist (lime, polished).
- Drying period built into the schedule before decoration.
- Waste removal and skip if required.
A single lump sum that says "plaster the lounge, £900" tells you none of these. You cannot tell if you are buying a skim, a replaster, or something in between, and you cannot compare it to anyone else's quote.
What is typically excluded (and why it matters)#
Items that get quietly left off:
- Painting and decoration. Plaster needs to dry fully before the first paint. The plasterer's job usually finishes at the dry surface, not the painted one.
- Substrate repairs. If the brick or stud underneath has damp, movement, or rot, that is a separate cost discovered once the old plaster comes off.
- Asbestos surveys. Pre-2000 properties with artex or textured coatings may need a survey before removal. A reputable plasterer will pause and quote separately.
- Moving and protecting furniture. You are normally expected to clear the room before the plasterer arrives.
- Plasterboarding. Repairing or replacing damaged board (rather than skimming over it) is usually priced separately.
- Mist coat and decoration. The diluted-emulsion mist coat that goes on first is almost always the decorator's job, not the plasterer's.
For the broader hidden-cost pattern across trades, see hidden costs in builder quotes.
Red flags specific to plastering#
- No mention of the coat system. "Plaster the room" with no specification of skim or replaster leaves the door open for either scope to be billed on the day. Insist on the coat system in writing.
- No prep allowance. Removing failing plaster, sheeting floors, and skipping waste is real work. A quote silent on it has either absorbed it (fine, ask) or skipped it (you will be charged extra).
- Painted in three days on a replaster. A backing coat needs 2–3 weeks to dry properly on a solid wall before paint. A quote that finishes and paints in three days has either skipped the backing coat, painted over wet plaster (it will peel within months), or excluded the painting without saying so.
- Cash-only, no VAT. A plasterer turning over more than £90,000 per year must be VAT-registered. A larger job priced cash-only often signals an undeclared trader, no public liability insurance, or both.
- No protection of carpet, flooring, or sockets. Plaster splatter is inevitable. Silence on dust sheets and socket masking means a clean-up bill of its own.
- Skimming over damp. New skim over a damp wall traps the moisture; the new finish blows within months. A fair quote inspects for damp first and either quotes remediation or holds the job.

Before you sign#
- Is the price within the typical band for your room size and region, given the scope?
- Is the coat system named: skim only, or backing plus skim?
- Is the m² or per-room area written down, not just a lump sum?
- Is the prep allowance there: stripping out, sheeting, masking, disposal?
- Is the drying period accounted for before decoration begins?
- Is the contractor VAT-registered and giving you a written quote (not a cash-only verbal)?
If three or more are missing, the quote is not yet in a state where you can fairly judge the price. Ask for an itemised re-quote before you compare it to other plasterers.

Frequently asked questions
- How much should a UK plastering job cost in 2026?
- A skim over sound plasterboard is £15–£25 per m². A full replaster (backing plus skim) is £30–£40 per m². By room, a full replaster runs £450–£650 for a small room, £600–£850 for a medium room, and £850–£1,150 for a large room. Ceilings cost slightly more than walls. London and the South-East sit at the top, the North and Wales at the lower end. See the plastering cost guide for the full breakdown.
- Why are some plastering quotes twice as much as others?
- Usually because they are pricing different jobs. A skim coat over existing plasterboard is roughly half the per-m² cost of a full replaster that strips back to brick and applies a backing coat first. A "cheap" skim quote and a "dear" replaster quote on the same room are both fair, for different scopes. Get both quotes to specify the coat system before comparing.
- What should a fair plastering quote include line by line?
- The coat system (skim only, or backing plus skim), prep (removing failing plaster, sheeting floors, masking sockets), the m² area or per-room price, beads and stops at corners and openings, and waste disposal. Each should have a price or quantity next to it, not just a description. A single lump sum hides whether you are getting a skim or a full replaster.
- Is replastering really that much more than skimming?
- Yes. A skim is one pass of finish plaster at 2–3mm thickness over a sound surface. A replaster strips off the failing plaster, applies a backing coat to bare brick or stud, and then skims on top. That is two coat systems, two drying periods, and a skip. The fully fitted price gap is typically £15–£25 per m² versus £30–£40 per m², before any substrate repair.
- How can I tell if my plastering quote is padded?
- Look for the pattern. A quote that is well above the regional norm, that is silent on the coat system (skim or replaster), that has no prep allowance, that promises the room "painted in three days" on a replaster, and that is cash-only with no VAT is showing several signs at once. One on its own usually has an innocent explanation; three together is the point to challenge the price or get the quote independently checked.
