Full House Plaster Pricing Guide: UK Skim & Re-plaster

Quick Answer: A UK full house plaster prices at £2,800-£4,800 for a 2-bedroom flat or terrace, £4,500-£7,500 for a 3-bedroom semi, £6,500-£10,500 for a 4-bedroom detached, and £9,500-£16,000+ for larger period properties with lath-and-plaster substrate. Skim-only finishes (over existing sound plaster or new plasterboard) are the lowest cost; full re-plaster on stripped walls is the highest. Allow 4-8 working days for a 3-bed semi inclusive of preparation, plaster, drying, and decoration handover.

Summary

Full house plastering is the highest-volume internal trade job in UK renovations. The pricing variability is significant — quotes for the same 3-bed semi range £4,000-£8,500 depending on substrate condition, ceiling work, and finish quality. The customer rarely understands what drives the variation; the trade must explain it during quoting.

The pricing variables: (1) substrate — new plasterboard takes a single skim coat (cheapest), existing sound plaster takes a skim coat with light bonding (mid), stripped masonry takes a 2-coat plaster (browning + skim) or 3-coat lime plaster system (highest), lath-and-plaster repairs are very expensive; (2) ceiling work — ceilings are typically 30-40% of total plaster area and slower than walls because of overhead working; (3) preparation — stripping wallpaper, repairing damaged plaster, sealing surfaces; (4) decoration handover — bare plaster vs mist-coated and painted.

This guide covers all common scenarios with material costs, room-by-room labour estimates, and the decoration follow-up. For external render see external render pricing guide; for interior decoration see interior decoration pricing guide.

Detailed Guidance

Substrate assessment — the pricing decision

The single biggest pricing variable is substrate condition. Before quoting, assess:

  1. Existing plaster soundness — tap-test walls for hollow patches (failed adhesion), look for crazing, cracking, blown plaster, water staining
  2. Wall construction — brick/block, lath-and-plaster (pre-1960 typically), timber stud (post-1980 mostly), stone (period properties)
  3. Damp condition — rising damp, penetrating damp, condensation — all need addressing before re-plastering
  4. Existing finish — paint type, wallpaper, artex, gloss surfaces
  5. Ceiling type — original plaster ceiling, modern plasterboard, lath-and-plaster, suspended/coffered

A proper survey is 30-60 minutes per floor. Without it, quotes are guesswork — a "skim only" quote can become a "bonding + skim" job if the existing plaster turns out to be blown.

Skim coat — the cheapest finish

Skim coating (also called "set" or "finish") is a 2-3mm finish coat of plaster over a sound substrate. Used for:

Typical sequence for skim on new plasterboard:

  1. Tape joints — paper tape or fibre tape with jointing compound, 24h dry
  2. First coat (laying-on) — apply by trowel, 1-2mm thick, level surface
  3. Second coat (finishing) — apply by trowel, 1-2mm thick, polish to smooth finish

Skim coat dries in 2-7 days depending on humidity, ventilation, and ambient temperature. Surface ready for decoration when fully dry — visible by uniform light pink colour change.

Labour: 30-50m² per day per skilled plasterer. Material cost £1-£2/m². Total cost £15-£25/m² installed at trade rates; £20-£35/m² at retail rates.

Bonding + skim — the standard re-plaster

Where existing plaster is blown, badly cracked, or removed, the wall needs a 2-coat re-plaster:

  1. Bonding coat — Thistle Bonding plaster (formulated for low-suction backgrounds), applied 11mm thick, scratched to provide key for finish coat
  2. Skim coat — 2-3mm finish coat over the bonding, polished smooth

Or for higher-suction backgrounds (brick, block):

  1. Browning coat — Thistle Browning plaster, applied 11mm thick, scratched
  2. Skim coat — as above

Total thickness: 13-15mm. Drying time: 4-10 days. Labour: 15-25m² per day per plasterer.

Cost premium over skim-only is typically 60-100%. Always confirm with the customer which substrate spec applies.

Lath-and-plaster — the heritage premium

Pre-1960 UK housing typically has lath-and-plaster walls and ceilings. Three coats of lime plaster over riven timber laths, finished with a lime putty top coat. Common failures: lath rot (especially in damp areas), plaster delamination from laths, ceiling sag.

Repair approaches:

  1. Patch repair — local removal and re-plaster with bonding + skim. £180-£480/m² for the patched area.
  2. Full strip and re-plaster — remove laths and plaster, board out with plasterboard, then skim. £75-£140/m². This is the most common modern approach but is NOT period-correct.
  3. Heritage replaster (lime) — strip back, replace laths, apply 3 coats of lime plaster (haired lime base, scratch, and finish). £140-£280/m². Period-correct, suitable for listed buildings.

Heritage lime plastering is a specialist craft — plasterers with lime experience are not common, and rates are 50-100% higher than gypsum plasterer rates. Always confirm the customer's preference for modernisation vs heritage approach.

Artex and textured ceilings

Pre-1992 ceilings may have artex containing chrysotile (white asbestos). NEVER assume artex is asbestos-free without testing. Asbestos-containing artex:

  1. Test — £50-£80 per sample at a UKAS-accredited lab
  2. Encapsulate — overboard with 12.5mm plasterboard and skim, leaves the asbestos intact and sealed. £25-£45/m².
  3. Remove — specialist asbestos removal contractor, licensed for textured coatings (TC). £60-£140/m² + waste disposal.

Most modern practice is to overboard rather than remove — cheaper, safer, no asbestos disposal cost. Always check pre-1990 ceilings for artex and inform the customer of the testing/encapsulation cost as separate items.

Drying time and decoration handover

Plaster needs to dry before decoration. Typical times:

Customer expectation management is critical. A "plastered house" is not ready for decoration immediately — it needs ventilation and drying time. Plaster painted before fully cured causes mist-coat flaking and paint adhesion failures within 6-12 months.

Mist coat (first paint coat, water-thinned emulsion at 70:30 paint:water ratio) seals the plaster ready for further coats. Always apply mist coat to fresh plaster, never undiluted paint.

Hidden costs and risk premium

The five most-missed cost lines in full house plaster quotes are: (1) preparation labour — stripping wallpaper, scraping flaking paint, removing fixtures (often 20-30% of total time); (2) protection of floors and furnishings — dust sheets, polythene sheeting, masking; (3) ceiling work — slower and more physically demanding than wall work; (4) angle beads at corners; (5) electrician follow-up — chase repairs from rewire work, socket make-good.

Risk premium of 15-25% is standard on pre-1965 properties. Premium of 25-40% if structural movement is evident (cracks reopening after re-plaster), if dampness needs addressing before plaster, or if heritage lime is required.

Frequently Asked Questions

Can the customer live in the house during a full re-plaster?

Difficult but possible if the work is staged. The plaster process is dusty (preparation phase), wet (during plastering — 2-3 days per room), and slow-drying (windows must be open, heating off, dehumidifiers running). Practical staging: start with one floor, finish that floor's plastering and drying, then move to the next floor. Customer needs alternative living space during the work day. For full empty re-plaster, vacant property is 25-40% faster and dust-cleaner.

What's the difference between skim and re-plaster?

Skim is a 2-3mm finish coat over a sound substrate (new plasterboard or existing plaster). Re-plaster is a complete 13-15mm system: a bonding or browning undercoat + skim finish, used where the existing plaster is failing. Skim is the cheapest finish (£15-£25/m²); re-plaster is 60-100% more expensive (£25-£45/m²). The customer's existing wall condition determines which applies.

How long does plaster take to dry?

Skim coat: 2-7 days. Bonding + skim: 5-12 days. Lime plaster: 21-90 days. Drying speed depends on ventilation (open windows), temperature (warmer is faster, but >25°C causes cracking), and humidity (drier is faster). Forced drying with dehumidifiers can accelerate by 30-50% but never use space heaters directly on fresh plaster — causes uneven drying and cracking.

Do I need to dry-line or plaster directly on brick?

Either works. Dry-lining (plasterboard dot-and-dabbed to brick, then skim coat) is faster, gives a flatter finish, and allows insulation behind. Plaster directly on brick (browning + skim, the "wet" plaster method) is more traditional and slightly thinner. Dry-lining dominates in new builds and most renovations; wet plaster on brick is more common in period restoration.

Is plastering Part-P notifiable?

No. Plastering itself is not notifiable under Building Regulations. However, plastering jobs that involve electrical work (rewiring during the plaster phase) ARE notifiable for the electrical work component — the plasterer typically waits for the sparks to complete first-fix before plastering begins. Always coordinate the sparks → plasterer → decorator sequence carefully.
