Wall Soundproofing Costs
Direct-to-Wall System (25–35 dB reduction)
A direct-to-wall system is the most space-efficient option, adding just 25–55mm to the room. It combines acoustic mineral wool, high-density acoustic boards and mass-loaded vinyl fixed using resilient clips.
- Materials for a typical 10m² party wall: £300–£550
- Professional installation: £800–£1,500 all-in
- DIY installation time: 1–2 days
Independent Stud Wall System (40–50 dB reduction)
An independent stud wall built away from the party wall with a full air gap delivers the highest performance and the most reliable way to meet Part E Building Regulations.
- Materials for a typical 10m² wall: £500–£900
- Professional installation: £1,200–£2,500 all-in
- Space required: 75–120mm from original wall
Floor Soundproofing Costs
Acoustic Underlay (15–22 dB impact reduction)
Acoustic underlays sit beneath carpet, laminate or engineered wood. They are the fastest DIY solution for reducing light footstep noise.
- 3mm rubber acoustic underlay: £3–£5/m²
- SilentMat 15mm floating floor mat: £15–£25/m²
- Typical 20m² room (materials only): £150–£500
Floating Floor System (30–40 dB impact + airborne)
For Part E compliance between flats, a floating floor system is required. This combines acoustic mineral wool between joists, SilentMat 15mm, and high-density boards as the walking surface.
- Materials for 20m² floor: £400–£900
- Professional installation: £900–£2,000
Ceiling Soundproofing Costs
Resilient Clip Ceiling System (25–35 dB)
Resilient clips decouple new plasterboard from the floor structure above, with acoustic mineral wool filling the void. This is the most effective ceiling treatment available.
- Materials for 15m² ceiling: £350–£700
- Professional installation: £900–£1,800
DIY vs Professional Installation
All SilentCloud systems come with full step-by-step installation guides and are designed for competent DIY installation. Labour typically adds 60–100% to material costs, so DIY installation can halve your project budget.
Is Soundproofing Cheaper Than Moving?
The average cost of moving house in the UK is £8,000–£15,000 when you include stamp duty, estate agent fees and removal costs. A comprehensive soundproofing treatment — even a full room — costs a fraction of this and solves the noise problem without the upheaval.
Cost vs Performance Summary
| Budget | Best Option | Typical Performance |
|---|---|---|
| Under £200 | Acoustic underlay, door seals, acoustic mats | 5–15 dB improvement |
| £200–£500 | Direct-to-wall system (partial wall) | 20–28 dB reduction |
| £500–£900 | Full direct-to-wall with MLV and resilient clips | 28–38 dB reduction |
| £900–£1,500 | Independent wall or floating floor/ceiling system | 38–50 dB reduction |
| £1,500+ | Full room — wall, floor and ceiling combined | 50+ dB, Part E compliant |
