The short answer
Soundproofing a wall in the UK typically costs around £30–£100 per square metre for materials and fitting, depending on the system. By project that usually works out at roughly £900–£2,000 for a single party wall, £2,500–£6,000 for a full room (walls plus floor or ceiling treatment), and £5,000–£12,000 for floors or ceilings between flats, which are the most involved. Material costs run from about £25–£50 per m² for acoustic mineral wool and £40–£80 per m² for acoustic plasterboard up to £50–£120 per m² for mass-loaded vinyl. The main drivers are the area treated, whether the noise is airborne or impact, and how many layers the build needs.
Price depends mainly on the area you treat, the type of noise you are fighting, and how many layers the system needs. The figures below are typical UK ranges for guidance, not quotations.
Typical UK costs
- Wall soundproofing£30–£100 / m²
- Single party wall~£900–£2,000
- Full room~£2,500–£6,000
- Floor/ceiling between flats~£5,000–£12,000
- Acoustic plasterboard~£40–£80 / m²
What drives the price
- Area treated: you pay largely per square metre, so one party wall costs far less than a whole room of walls, floor and ceiling.
- Type of noise: blocking impact noise such as footsteps usually needs more separation and mass than blocking airborne noise such as voices, so it costs more.
- System & layers: a direct-to-wall board is the lowest-priced route, while an independent stud wall or a resilient-bar build adds material and labour.
- Access & making good: removing skirting, moving sockets, re-skimming and redecorating all add to the figure.
| Project | Typical range | Notes |
|---|---|---|
| Wall (per m²) | £30–£100 / m² | varies by system & layers |
| Single party wall | ~£900–£2,000 | one shared wall |
| Full room | ~£2,500–£6,000 | walls plus floor or ceiling |
| Floor/ceiling between flats | ~£5,000–£12,000 | impact noise, most involved |

What the materials cost
No single product soundproofs a wall on its own — performance comes from combining mass, separation and absorption. As a rough guide to material cost: acoustic mineral wool runs about £25–£50 per m², acoustic plasterboard about £40–£80 per m², and mass-loaded vinyl about £50–£120 per m². Resilient bars or acoustic clips, which decouple the new surface from the structure, are a smaller line but a big part of why a system works. Layering these is what moves a build from the lower end of the range to the higher end.

Frequently asked questions
How much does it cost to soundproof a wall in the UK?
Typically around £30–£100 per square metre for materials and fitting, which works out at roughly £900–£2,000 for a single party wall. The figure depends on the system used, how many layers it needs, and whether you are blocking airborne or impact noise.
How much does it cost to soundproof a whole room?
A full room — walls plus floor or ceiling treatment — commonly costs around £2,500–£6,000. Floors or ceilings between flats are the most involved and often run £5,000–£12,000 because impact noise needs more separation and mass.
Why is the soundproofing price range so wide?
Because builds and noise problems differ. The area you treat, whether the noise is airborne or impact, and how many layers the system needs all move the figure. An on-site assessment gives the accurate number for your home.
