Soundproofing London
Noise is one of the most common complaints in London homes — flats stacked on flats, converted houses with thin party walls, and HMOs where every room borders another. The good news is that most of it is fixable, but only with the right build-up: soundproofing is a system, not a single product, and the cheap foam panels sold online do almost nothing against the impact and airborne noise that actually disturbs people.

Soundproofing London
Noise is one of the most common complaints in London homes — flats stacked on flats, converted houses with thin party walls, and HMOs where every room borders another. The good news is that most of it is fixable, but only with the right build-up: soundproofing is a system, not a single product, and the cheap foam panels sold online do almost nothing against the impact and airborne noise that actually disturbs people.
Real soundproofing combines mass, absorption and isolation. A properly upgraded wall, floor or ceiling layers mineral wool to absorb sound, resilient bars to decouple the plasterboard from the structure, acoustic-grade boards for mass, and mass-loaded vinyl where extra density is needed — so the assembly both blocks airborne noise and breaks the path that carries footsteps and bass through the building.
We soundproof walls, floors and ceilings across London — from a single noisy party wall to a whole room or a flat conversion that has to meet Approved Document E. For conversions and HMOs the regulations set the standard the separating walls and floors must achieve, and as a leaseholder there are usually freeholder and lease considerations to work within, which we flag early.
What's Included
- Survey diagnosing airborne versus impact noise and the path it travels
- Acoustic specification matched to the wall, floor or ceiling
- Mineral-wool absorption infill within the assembly

- Layered acoustic-grade plasterboard for added mass
- Mass-loaded vinyl where extra density is required
- Sealed junctions to stop flanking noise, then skim and make good
- Approved Document E build standard and testing for conversions and HMOs

Our Process, Step by Step
Survey & diagnose the noise path
We establish whether the problem is airborne noise (voices, TV, music) or impact noise (footsteps, bass) and trace how it is travelling — through the wall, the floor, the ceiling or flanking around them. The build-up only works if it targets the actual path, so this step decides everything.
Specify the acoustic build-up
We specify the right system for the element and the target — mineral wool, resilient bars, acoustic board and mass-loaded vinyl in the appropriate combination — and, for conversions and HMOs, build it to meet the standard Approved Document E requires. You get a fixed, itemised quote.
Install walls, floors & ceilings
We build the acoustic assembly: independent or upgraded studwork with mineral-wool infill, resilient bars to decouple the boards, layered acoustic plasterboard for mass, and mass-loaded vinyl where density is needed — sealing all junctions, because gaps let sound straight through.
Finish & test where required
The new surfaces are skimmed and made good ready for decoration. Where the work creates a new separating wall or floor in a conversion, we arrange the pre-completion sound testing that building control requires to confirm the assembly meets Part E.
Frequently Asked Questions
Upgrading a wall or partition with an acoustic build-up typically costs £40–£90 per square metre. Soundproofing a whole room — treating the walls plus the floor or ceiling as needed — usually lands at £1,000–£3,000 depending on size and how many surfaces need work. Acoustic floors and ceilings are priced per square metre after survey. We quote a fixed price once we have diagnosed the noise path.
Not for the noise most people want to stop. The acoustic foam sold cheaply online is designed to reduce echo within a room, not to block sound passing between rooms. Stopping airborne and impact noise needs mass, absorption and isolation working together — mineral wool, resilient bars, acoustic plasterboard and sometimes mass-loaded vinyl — built into the wall, floor or ceiling. That is what we install, and it is what genuinely makes a difference.
Approved Document E is the part of the Building Regulations covering resistance to the passage of sound. It sets the performance standard that separating walls and floors must meet in new dwellings and, crucially, in material changes of use such as converting a house into flats or an HMO. For those conversions the new separating elements must meet the standard and are usually proven by pre-completion sound testing — which we build to and arrange.
To an extent — there is always a trade-off between acoustic performance and lost space, because effective soundproofing relies partly on decoupling and mass, which take depth. We specify the thinnest build-up that will hit your target, using independent linings, resilient bars and high-mass boards rather than simply adding bulk. At survey we are honest about how much improvement is realistic for the depth you can give up.
Usually yes, but there are considerations to work within. As a leaseholder, altering the structure or fabric of separating walls and floors often needs freeholder consent under the lease, and some works affecting the building cannot be done unilaterally. We flag these early so you can get any consent needed, and we focus the works on the elements you are entitled to treat — which is frequently enough to make a real difference.
