How much does a soundproof room cost in 2024?

Whether you want to reduce noise from neighbours or create a cosy home cinema room, soundproofing could be the answer. But, how much does a soundproof room cost? Find out in this handy cost guide.

Fast Facts

  • On average, the total soundproof room cost in the UK is around £11,050 - £20,650
  • Creating a 25m2 insulated stud wall in front of existing wall costs about £4,200 (materials and labour)
  • There are a variety of ways to soundproof a room so speak to local soundproofing experts for their professional advice

To address issues of unwanted noise, it’s important to understand where and how the sound is travelling. That way you can effectively plan your soundproofing.

We’ve put together this guide to talk you through the various soundproofing options and the costs involved.

How much does it cost to soundproof a room in the UK?

The average soundproof room cost will depend on the specifications of the room.

To help you plan your budget, here are some average costs to soundproof a room in the UK:

Soundproof room costsMaterialsLabourTotal
Create an insulated stud wall in front of existing wall (25m squared)£2,400£1,800£4,200
Add acoustic plasterboard with batons to existing wall (25m squared)£900£1,700£2,600
Insulate existing stud wall (25m squared)£700£1,100£1,800
Add soundproof flooring (10m squared)£1,200£900£2,100

If you’re looking into the cost of soundproofing an entire room, you’ll need to factor in wall, floor and ceiling soundproofing.

The average soundproof room cost for a square room with four 25m2 walls and a 10m2 floor and ceiling would be in the region of £11,050 - £20,650.

What’s the cost of soundproofing a semi-detached house?

If you’re looking to soundproof an entire semi-detached house, you’re looking at a soundproofing cost of around £30,000.

Before going ahead with the project, speak to local soundproofing trades to understand if you need to soundproof the whole house.

Often, it’s only certain rooms or parts of the house that you need to soundproof to deal with noise issues.

Cost to soundproof a second-floor bedroom

Let’s assume you need to soundproof a second-floor bedroom with significant noise from the walls and floor.

Using the most comprehensive wall soundproofing, the average cost of soundproofing a second-floor bedroom is around £18,900 (materials and labour).

If you opt to insulate the existing stud wall, the average cost is about £9,300 (materials and labour).

Cost to soundproof a lounge

If you have unwanted noise coming from next door when you’re trying to relax in your lounge, then you can insulate just one wall rather than the whole room.

In this situation, the average cost would be £4,200 to create a new stud wall, or £700 to just insulate the existing stud wall.

You’re not alone in asking how much soundproofing a room costs. Hopefully, you now have an idea of the cost of your project.

The next step is to get quotes from professionals to get an accurate price for your project.

Hourly rates for your soundproof room cost

The hourly rates for soundproofing a room will vary depending on the individual tradespeople you hire and where in the country you live.

As a guide, you can expect to pay around £35 to £40 per hour, or about £300 per day – based on a two-person team with local trades.

If you choose a dedicated specialist soundproofing engineer, the cost is typically higher at about £500 per day.

Calculating your soundproof room cost

One common mistake people make when calculating the cost of soundproofing is forgetting to include the cost of labour – which is a significant part of the total soundproofing price.

This price of labour will vary depending on the complexity of the room you want to soundproof. Where you live can also affect the price – with labour costing more in and around London.

The average time for soundproofing a room is 2 – 4 days.

How does soundproofing work?

To understand how soundproofing works, it’s useful to know that there are two different types of noise that you’ll be dealing with:

  • Airborne noise travels from one space to another through the air, e.g. high-pitch sounds such as whistling or shouting/screaming
  • Impact noise (also known as flanking noise) is sound that travels through materials, e.g. noise from washing machines, feet stamping and objects dropping onto hard floors

Soundproofing a room involves using different types of material to tackle these two types of noise.

Generally, fibrous materials like foam work well at blocking high-pitch airborne noise, while rubber sheets are particularly good at stopping impact noise.

Once you establish your approach, you’ll have a better idea of your total soundproof room cost.

Ways of soundproofing a room

Commonly, there are three different ways to soundproof a room – each with a different price tag.

  • Block noise travelling through the air by adding a thick layer of a heavy material to a wall, ceiling or floor
  • Reduce impact noise by using a damping compound in between the layers of a wall, floor or ceiling
  • Absorb unwanted sound by using soft furnishings, curtains, plants and other sound-absorbent materials

The method you choose for your room and the associated soundproof room cost will depend on where you’re soundproofing.

Walls, floors, ceilings and doors each have requirements to consider for reducing noise travelling between rooms.

How to soundproof a wall

There are various ways to reduce the amount of noise that passes through walls.

The method you choose and the size of the walls in your room will affect how much soundproofing walls will cost you.

Create a second wall

The most effective way to soundproof a wall is to create a second wall in front of your existing wall, leaving a gap between the two (ideally 100-150mm).

The gap is then filled with soundproofing materials that will absorb sound passing through the wall. Foam, rubber sheets and fibrous material are some of the most commonly used for this.

To minimise sound vibrating through the walls, there should be minimal contact between the new wall and the existing wall.

This can be achieved by securing the new wall using the floor and ceiling, creating a standalone effect.

It’s also important to know that you’ll lose space due to the depth of both the new wall and the gap.

Fix a new wall to your existing wall

If you don’t have the luxury of space to lose by creating an independent new wall, a popular alternative is to fix a new wall directly onto your existing wall.

This is done using a metal or wood framework, which creates a much smaller gap of approximately 30mm that is then filled with fibrous material glued to your existing wall.

A double layer of acoustic plasterboard is then fixed to the bars of the framework with a rubber sheet sandwiched between them.

This is a popular option for many homeowners as you can buy all the necessary materials off the shelf.

Use rubber mat and plasterboard

Another option that can help reduce airborne noise travelling through a wall is to fix a thick sound-absorbing rubber mat directly onto your existing wall and then fix two layers of acoustic plasterboard on top of it.

For additional soundproofing for your wall, you can add a thin layer of acoustic rubber between the two layers of plasterboard.

This option isn’t great at reducing impact noise as the materials are fixed directly onto your existing wall, allowing sound vibrations to still travel through the wall.

Insulate a stud wall

If you are planning to soundproof a stud wall and you don’t have space to lose in your room, you have the option to insulate the existing wall.

This option will stop some of the airborne noise coming through the wall but has little impact on impact noise vibrating through the wall.

To insulate the wall, the original outer plasterboard is removed, and the gap behind it is filled with acoustic insulation, such as Rockwool.

Acoustic plasterboard is then used to replace the original plasterboard to provide an extra layer of sound protection.

With this option, you can always add another layer of acoustic plasterboard with a rubber sheet sandwiched between the two plasterboard layers.

This will further reduce the amount of airborne sound passing through the wall.

Whatever your budget, it’s best to discuss your plans with a professional tradesperson first to get their advice and discuss the price of soundproofing your walls.

Soundproofing a floor

Acoustic floor insulation will prevent airborne sound from travelling through wooden floors and can be added between floor and ceiling joists.

Other options, such as floating floors and acoustic matting, can be used under carpets or hardwood flooring, to give a significant sound reduction for impact noise.

However, you’ll need to consider the floor finish and height. Identifying the structure of the existing floor and adjacent walls is an important factor to consider when deciding what approach to take.

Many flats and apartments are made of concrete, whereas period houses will usually be made of brick and timber.

In properties with a concrete structure, you’ll be able to apply soundproofing acoustic insulation directly to the concrete.

Here are some of the main ways you can achieve results:

Acoustic matting

Matting is commonly used on top of a timber structure and underneath floor finishes such as wooden floors and carpets. It’s an ideal way of soundproofing your floor against impact noise.

Acoustic matting is fairly easy to install as the mats can be cut into shape using a sharp knife and then put into position, often in a brick-like pattern.

To reduce movement and potential damage to the edge of the flooring finish above, it’s recommended to add a layer of ply on top of the matting.

Floating floors

This method uses an interlocking system with tongue and groove edges that slot together to hold them in place.

When you buy soundproof floating floors, they come ready to lay directly on the existing floor and will reduce the amount of sound that passes through them to the room below.

Soundproofing panels

Using acoustic panels is another effective way of reducing the amount of airborne or impact sound that travels through your floor to the room below.

They can either be laid directly on top of your existing floor, or laid onto the joists.

By adding these panels, you’re increasing the mass of the floor structure, which enables it to absorb more sound and, therefore, decrease the amount of noise heard below.

Insulation materials

This option is a great way to reduce airborne sound and is popular for use on floors, walls, and ceilings.

One thing to watch out for is not using thermal insulation rolls for your soundproofing project. Thermal rolls are much less dense, which makes them unsuitable for absorbing sound.

Instead, make sure that specific acoustic insulation slabs are used to maximise your floor’s sound absorption.

Each home is different and the cost of soundproofing floors will vary from room to room.

We recommend taking time to understand the type of structure you have in your home and discussing the options with a professional to ensure you choose the right soundproofing for your floor.

How to soundproof a ceiling

Flooring soundproofing tends to absorb vibration better than ceiling solutions.

Reducing impact noise at the source is much more effective. This minimises the amount of vibrations entering the building’s structure.

However, if you live in an apartment block or converted building where you don’t have access to the floor above, soundproofing your ceiling is the next best option.

To help you carry out a soundproof room cost evaluation, here are the three common ways you can soundproof a ceiling:

Use acoustic insulation

Acoustic insulation slabs are one of the most effective ways to absorb sound, and the thickness of the material is key to achieving the necessary soundproofing results.

You can install compressed acoustic insulation slabs into the cavities of the ceiling for increased density and maximum sound absorption.

The insulation slabs will need to be at least 100mm thick and ideally have a density of 60kg/m³ to achieve a decent level of sound absorption.

Install soundproofing panels

An alternative to acoustic insulation is to use soundproofing ceiling panels instead. These will add mass to your ceiling, which reduces the amount of sound that can travel through it.

These panels are usually made of cement particle board, which offers a better result than an acoustic plasterboard.

The increased density of the panels reduces the vibration passed to the room below, so less noise can be heard from above.

This method of soundproofing your ceiling is often the most cost-effective. It can be done without opening up your existing ceiling or constructing a new one.

Build an independent ceiling

Creating an independent ceiling underneath your existing ceiling structure is often the most effective way to reduce noise penetration.

However, it usually means it’s the soundproofing ceiling method with the highest price tag.

It also requires losing height within the room, which makes it more appropriate for properties with higher ceilings.

Current building regulations stipulate a minimum drop of six inches. That can make it an unachievable option for many homeowners.

If you do have the space to create a new ceiling, it is a very effective solution for tackling both airborne and impact sound.

In most cases, new ceiling joists will need to be installed. We recommend that you use a professional tradesperson to do the job.

How to soundproof a door

There are several ways to soundproof a door and reduce unwanted noise, including:

  • Make sure the door seals properly when it’s closed, if not the seal needs to be repaired or replaced
  • If you have a hollow light door, swapping it for a heavier solid one can make a big difference
  • Installing specialist soundproof doors that are acoustically rated can be a great solution but they’re often quite expensive

With doors, there are three ways to address problematic sound travelling through them:

Add panelling to your door

Hollow doors are easily penetrated by sound. If you can’t replace them, you can add thickness to them by adding a piece of dense material to the door panel, such as MDF.

These panels are quick and easy to install and are available in a range of styles to suit your home.

Fill gaps around the door

There are, in fact, two potential gaps that you might need to deal with around the door.

The first is between the door frame and the wall, which can usually be easily filled using an architrave.

An architrave is a type of interior moulding that sits around the frame of a doorway (or window). It’s typically available in a range of materials that can be finished with either paint, stain or varnish.

The second potential gap is between the door itself and its frame.

Here you’ll need to remove any existing architrave. Then fill any gaps with a dense soundproofing rubber or acoustic sealant and replace the architrave.

Address the gap at the bottom of the door

This is often the greatest offender for sound to pass through and also happens to be the hardest to overcome.

Floors are rarely level and the gap between the door and the floor usually changes between the door being open and when it’s closed.

An automatic door bottom can prove to be an effective solution. That’s because it automatically rises when the door opens. And then drops back into place when the door closes.

Soundproofing materials

Types of soundproofing materials

One of the key factors that will impact the overall price of your soundproof room is the type of material you use.

Below are three of the most common types of soundproofing material used in the UK:

Acoustic plasterboard

Soundproofing plasterboard is a much higher-density version of regular plasterboard. The extra density allows it to reduce noise travelling through it effectively.

It’s often used in walls and ceilings to reduce the noise coming from either side of the wall/ceiling structure.

Use it with acoustic insulation materials to achieve optimum results from acoustic plasterboard.

Acoustic plasterboard adds mass that increases the overall density of a wall or ceiling. This makes it much more difficult for sound to travel through.

Acoustic panels

Soundproofing panels are a particularly cost-effective way to reduce noise.

Panels, commonly made from wood and fibreglass, come in a range of sizes and can be easily mounted on walls and/or ceilings.

They can also be made of other materials, including acoustic foam, polypropylene, polyester, and cotton.

They’re great for soundproofing because they act in two ways: absorbing sound as it passes through and reducing the noise level within the room.

Dense foam soundproof panels are perfect for absorbing sound and muffling noises to make them much less audible.

If you aren’t planning to cover the entire surface, you’ll want to distribute acoustic panels evenly on the wall or ceiling.

There are two common ways to attach acoustic panels by using either clips or the cloud mounting method:

  • The clip method will use one of a variety of clip systems, such as attaching one part of the clip to the wall and the other part to the panel itself
  • Cloud mounting is used to create a floating effect for acoustic panels hanging from the ceiling using eyebolts

Acoustic roll

Acoustic roll is usually made of lightweight, non-combustible glass mineral wool. It’s used for walls and floors and works in a very similar way to acoustic slabs.

The roll increases the density and mass of the wall or floor structure. This acts as an effective solution for absorbing sounds and reducing noise.

It can be used in both domestic and commercial properties, and its roll format makes it easy to fit into any space.

Acoustic roll is particularly effective when used in conjunction with acoustic insulation products.

Pros and cons of soundproofing a room

If you’re still on the fence about soundproofing, here are some of the pros and cons to consider:


  • Soundproofing reduces the amount of noise coming from outside and creates a more peaceful environment
  • It provides you with a greater level of privacy as the homeowner
  • Soundproofing a room allows you to minimise sound coming from outside as well as inside the house
  • It allows creative work, such as making music or recording visual content, to take place without disturbing (or being disturbed by) people in neighbouring rooms or properties
  • For places where confidential information is often discussed, such as banks and doctor’s surgeries, it can provide a much-needed level of privacy
  • The cost of a soundproof room can be kept to more modest budgets using DIY techniques


  • Properly soundproofing your home can be expensive, even for just a single room
  • There is a risk of damaging electrical wiring and pipework during the installation process
  • By blocking out unwanted noises, you may also block out necessary sounds, such as fire alarms, children crying or the doorbell
  • Installing soundproof materials can be a pain in existing homes due to the structure of the building
  • Ongoing maintenance work on cables and pipes can become more complicated for rooms with soundproofing
  • Some soundproofing solutions can be unattractive to look at if left open, rather than being enclosed properly

What are the benefits of soundproofing a room?

If you live in a property with thin walls, floors or ceilings, there are numerous benefits of soundproofing a room…

  • Reduced noise pollution – With fewer unwanted sounds, you’ll have a more calm and peaceful home
  • Improved privacy – You’ll be able to have private conversations without worrying about being overheard
  • Better sleep – One of the great benefits of soundproofing is the improved quality of sleep that you get in a quieter environment
  • Add value to your property – Soundproofing can often increase the value of your home by making it a quieter and more desirable space
  • Be happier and healthier – Stress isn’t good for us and by removing the aggravation of unwanted noise you can reduce anxiety and promote better health and well-being
  • Meet Building Regulations – As of 2003, all new buildings and refurbishments in England need to meet a rough guide target of 45 decibels for airborne noise resistance

Soundproofing your home to ensure good sleep

Will soundproofing my room make a difference?

Done properly, soundproofing is an effective way to reduce sound coming through your walls, floor or ceiling.

Most newly built homes have soundproofing built in. If you live in an older property, you could majorly benefit from soundproofing.

Should I try soundproofing paint first?

Soundproofing paint is chiefly aimed at reducing noise within a room. It’s not considered a solution for sound coming through a wall, floor or ceiling.

This kind of paint minimises ringing caused by sound bouncing off metal surfaces, which is why it’s often used in warehouses.

A layer of paint isn’t likely to make much of a difference. Instead, it may be worthwhile consulting a soundproofing professional.

Will underlay soundproof my floor?

Standard underlay undoubtedly has soundproofing qualities and an extra layer might help to reduce noise from below.

There are also purpose-made sound-reducing underlays available. All of them aim to minimise both sounds coming through your floor and dampen echoes within your room.

Do I need planning permission to install soundproofing?

The UK requires no legal approval or permission before installation, at the time of writing.

Is it expensive to soundproof a room?

That depends on the size of the room and the type of soundproofing you’re planning to install.

As a rough guide for your soundproof room cost, here are some average prices for soundproofing methods in the UK:

  • Create an insulated 25m2 stud wall in front of the existing wall – £4,200
  • Add acoustic plasterboard with batons to existing 25m2 wall – £2,600
  • Insulate existing 25m2 stud wall – £1,800
  • Add 10m2 of soundproof flooring – £2,100

Can you soundproof a room 100%?

The reality is that it’s almost impossible to 100% soundproof a room in a domestic property. Some small amount of noise will always get into the room.

That said, with professional soundproofing, you will be able to reduce as much unwanted noise as possible.

How much does it take to build a soundproof room?

To build a soundproof room, you will need to tackle the walls, floor, ceiling and door(s).

Only by addressing all those elements will you be able to properly soundproof a room.

To understand the best way to build a soundproof room in your home, speak to experienced local soundproofing experts.
