Estimate Your Soundproofing Cost in 30 Seconds
Pick what you are treating, the performance level and your region for an instant 2026 materials-and-labour estimate.
How This Calculator Works
We take the base cost for your project, apply a performance-level multiplier and then a regional multiplier, using real 2026 UK materials-and-labour quotes.
Project Base Costs (materials + labour)
- Single party wall — ~£1,450 (£900–£2,000)
- Ceiling only — ~£2,800
- Full room (walls + ceiling) — ~£4,200 (£2,500–£6,000)
- Floor & ceiling (between flats) — ~£8,200 (£5,000–£12,000)
London and the South East run 10–25% higher than the baseline.
Performance & Regional Multipliers
- Standard acoustic 1.00× · High-performance / Part E 1.35×
- London 1.25× · South East 1.12×
- Midlands & East 1.00× (baseline)
- South West & Wales 0.95× · North & Scotland 0.90×
Flat conversions must meet Building Regulations Part E. A real quote follows a site survey.
Typical Soundproofing Costs (2026)
Materials + labour project totals, Midlands baseline; Part E / high-performance applies ×1.35.
| Project | Standard acoustic | High-performance / Part E |
|---|---|---|
| Single party wall | £900–£2,000 | £1,215–£2,700 |
| Ceiling only | ~£2,800 | ~£3,780 |
| Full room (walls + ceiling) | £2,500–£6,000 | £3,375–£8,100 |
| Floor & ceiling (between flats) | £5,000–£12,000 | £6,750–£16,200 |

What drives the cost of soundproofing
The first question a specialist asks is what kind of noise you are dealing with, because airborne noise — voices, TV, music — and impact noise — footsteps, doors, moving furniture — need different treatments. Airborne noise through a shared wall is the cheapest to tackle; impact noise through a floor between flats is the most involved and the most expensive, because it means isolating the whole floor build-up rather than just adding mass. The surface you treat, the existing construction (a dense solid wall behaves very differently from a hollow stud partition), and how sound flanks around the junctions all shape the design.
After that, performance level and finish drive the number. A standard acoustic upgrade uses added mass and absorption; a high-performance or Building Regulations Part E system uses independent layers and resilient bars and costs around a third more. Bigger rooms need more material, tight ceilings limit what you can build down, and any sockets, radiators or pipework in the way have to be moved. The acoustic layers also eat into the room, so re-plastering, new skirting and redecoration are usually quoted on top by other trades. Our soundproofing cost guide breaks down each system, the plastering cost guide covers the making-good that follows, and you can compare vetted local specialists through our soundproofing hub.
