Air Duct Cleaning Cost

Air ducts can quietly collect dust, pollen, pet hair and even mould over time, which can affect the air you breathe and make your heating or ventilation system work harder than it needs to. Whether you have ducted warm air heating, a mechanical ventilation (MVHR) system or long extractor fan runs, cleaning them every few years helps keep air flowing freely and your system running efficiently.

In this guide, we’ll cover how much air duct cleaning costs in the UK, what affects the price, how long the job takes and signs your ducts need attention. Ready to book? Compare quotes from local duct cleaners today.

How Much Does Air Duct Cleaning Cost?

The cost of air duct cleaning in the UK depends on the type of ventilation system you have, how much ductwork there is, accessibility and contamination levels.

A small domestic extract duct can cost between £50 and £100 to clean, but if you have an MVHR (mechanical ventilation with heat recovery) system serving your whole house, the cleaning bill can come to several hundred pounds. Commercial ductwork and kitchen extraction can cost a lot more.

Here are some examples of what you can expect to pay for common air duct cleaning services.

Prices will depend on what the service includes. For example, an MVHR service that covers filters and the ventilation unit might not include cleaning every duct run.

Grease deposits, access panels, duct length and reporting requirements can also have a big impact on commercial kitchen extraction prices.

These prices are estimates rather than fixed quotes. The final cost will depend on your system and the work required.

Air Duct Cleaning Cost Breakdown

There are several things that may or may not be included in your final bill for air duct cleaning.

If you're unsure what's included in your quote, ask for an itemised breakdown.

You should also check whether VAT, replacement parts, access equipment and post-cleaning documentation are included. Finding out exactly what's covered can help you avoid paying for the same services twice.

Domestic Air Duct Cleaning Cost

Most UK homes use radiators or underfloor heating instead of complex ducted heating systems. This is why domestic duct cleaning is more likely to involve ventilation, bathroom extraction, kitchen extraction or ducted air conditioning.

A small extract duct can cost between £50 and £100, but cleaning a bigger network can mean a bill of several hundred pounds.

The number of outlets you have, duct length, contamination and access can all have a big impact on the final price.

Common domestic systems include:

• MVHR: Supplies fresh air and extracts stale air while recovering heat.
• MEV: Uses a central mechanical unit to extract air from rooms like kitchens and bathrooms.
• Ducted air conditioning: Distributes conditioned air through supply ducts and sends air back through return paths.
• Warm-air heating: Uses ductwork to distribute heated air around your property.

These systems all have their own components and cleaning requirements, so make sure the quote you get relates to the specific type of system you need help with.

MVHR Duct Cleaning Cost

Mechanical ventilation with heat recovery (MVHR) systems are found in many energy-efficient homes today.

They use separate supply and extract ducts to maintain airflow while recovering heat from outgoing air.

An MVHR service that includes some duct cleaning can cost around £150-£400. What you pay will depend on your property and the work that's needed. If you have a bigger or more complex installation, you can generally expect to pay more.

A full whole-house duct clean may also cost more than a routine MVHR service, so it's important to check exactly what you're being quoted for.

The agreed work may cover:

• Supply and extract duct runs
• Air valves and grilles
• Accessible parts of the ventilation unit
• Heat exchanger cleaning
• Filter replacement if needed
• Basic checks after cleaning

Filter changes, cleaning the unit and cleaning the entire duct network are different tasks. Ask the company what's included and never presume that an annual service will cover every duct.

Make sure you follow the manufacturer's filter maintenance instructions. Government guidance on home ventilation also advises homeowners to follow manufacturer recommendations when maintaining ventilation systems and replacing filters.

MEV Duct Cleaning Cost

The job of mechanical extract ventilation, or MEV, is to remove stale air through a central fan and connected extract ducts.

It's different from MVHR as it doesn't use a heat exchanger to recover heat from outgoing air.

Costs are influenced by the number of extract points, how long each duct run is, the condition of the fan unit and accessibility.

It can cost less to clean a single extract point and short duct than a whole central system.

Any quote you get should explain whether the service includes the central fan, ductwork, grilles and valves.

Air Conditioning and Warm-Air Heating Duct Cleaning Cost

Ducted air conditioning cleaning can cost between £380 and £1,150 for a whole system, with size, access and layout influencing the price. Commercial installations can cost considerably more.

The work may cover supply ducts, return-air paths, diffusers, grilles and accessible internal surfaces.

It's important to remember that cleaning ductwork isn't the same as servicing air conditioning equipment. Refrigerant checks, electrical repairs and other maintenance work are usually listed separately.

Warm-air heating systems also need to be approached according to their specific requirements.

Costs will depend on the number and condition of supply ducts, return-air paths, grilles and accessible components. Unless servicing is included in your quote, you'll need to arrange this separately.

Commercial Air Duct Cleaning Cost

Commercial ventilation cleaning can cost around £350-£750 for a small office or retail system, but larger buildings can cost £1,500-£2,500 or more.

The size and complexity of the network and the amount of work needed will have a big influence on the price.

Factors taken into account when pricing this work include:

• The number of floors and duct branches
• Total duct length and system layout
• Access panels and concealed sections
• Ceiling height and access equipment
• Contamination levels
• Whether out-of-hours working is needed
• Inspection records and post-cleaning reports

Commercial quotes can be priced in different ways.

You might get a fixed system price, a price based on duct area or one based on access needs and labour requirements.

Per-metre rates are sometimes used, but larger, more complex buildings can make this an unsuitable way to calculate costs.

Commercial Kitchen Extract Duct Cleaning Cost

Commercial kitchen extract cleaning can be quite different from general ventilation, as large amounts of grease can gather inside canopies, filters, ductwork and fans.

Small kitchen systems can cost around £450-£1,200 to clean, but larger restaurant or hotel systems can cost several thousand pounds.

What you'll ultimately pay depends on how much grease build-up there is, the type of cooking that takes place, duct length, access needs and how many extraction systems there are.

The work might include degreasing the canopy, cleaning filters and ductwork, cleaning the extraction fan, taking photographs and producing a report after the work has taken place.

Make sure you don't confuse a basic canopy clean with a full extraction system clean, as these are different services.

Confirm which sections are included and find out whether the quote covers access panels and documentation.

Air Duct Cleaning Cost Per Vent or Metre

Some contractors price small jobs by the outlet, but others will quote for the whole system.

A system with six outlets that are easy to access and have short duct runs can cost a lot less than one with six outlets connected to long, hard-to-access branches.

Commercial ductwork can be priced by area, length or the overall scope of the work.

Ask the contractor to explain the pricing method and confirm that all the parts of the network you need cleaned are included.

What Affects Air Duct Cleaning Costs?

There are several factors that can affect how much you pay for air duct cleaning.

System Size and Number of Vents

Bigger networks tend to take a lot longer to inspect and clean. The more outlets and branches there are, the greater the labour and equipment requirements become.

Accessibility

If you have ductwork in lofts, ceiling voids, risers or high-level areas, extra preparation or access equipment may be needed.

Missing access panels can also increase your costs.

Contamination and Condition

Light dust deposits may require less work than heavy debris, grease or contamination after water damage.

Damaged ductwork may need to be repaired or replaced instead of cleaned.

Duct Material

Rigid metal ducts and flexible ducts can need different cleaning methods.

The material, condition and manufacturer's guidance can all have a big influence on what can safely be done.

Location and Working Hours

Labour rates vary across the UK. You can expect to pay more in London and the South East in some cases, or if you need commercial work to take place overnight or outside normal opening hours.

What Does Air Duct Cleaning Include?

What the work involves can vary from one project to another.

A complete quotation might cover an initial inspection, preparation, internal duct cleaning, cleaning of supply or extract outlets, removal of loosened debris, cleaning of accessible components, reassembly and any agreed post-cleaning checks.

Cleaning methods can include mechanical brushes, agitation equipment, compressed air and vacuum extraction, depending on your system.

Before you accept a quote, ask:

• Which duct runs will be cleaned?
• Are all grilles, valves and diffusers included?
• Is the fan or ventilation unit included?
• Are filters and replacement parts extra?
• Will any access panels need to be installed?
• Is a camera inspection or written report included?
• Are VAT and access equipment included in the total?

A detailed written quote covering all the work you need will make it easier to compare quotations.

Air Duct Cleaning vs Ventilation Servicing

Duct cleaning focuses on removing debris or contamination from the duct network.

Ventilation servicing is more related to the operation and maintenance of components like fans, filters, controls and heat exchangers.

A service visit won't necessarily include full duct cleaning, and duct cleaning doesn't automatically include repairs, filter replacement or airflow balancing.

Make sure you confirm the work you need before accepting a quote so that it covers the problem you want addressed.

It's worth comparing a few quotes before choosing a company, so you can see what's included and how the prices differ.

Do Air Ducts Need Cleaning?

Not all ventilation systems need frequent whole-network cleaning.

When deciding whether cleaning is necessary, consider the system, its condition, maintenance history and any evidence of contamination.

Some reasons you might want to arrange an inspection include visible debris at outlets, confirmed contamination, pest activity, water damage or dust that has entered the system during building work.

Reduced airflow can also mean you have blocked filters, fan problems or an airflow-balancing issue rather than dirty ducts.

If you suspect you have mould, you need to get the underlying moisture source investigated.

Condensation, water ingress, poorly insulated ducts or other system problems may be contributing to the issue. Cleaning alone might not stop mould from returning, and damaged materials may need replacing.

After renovation work, check whether dust and debris have actually entered the ductwork before arranging a full clean.

How Often Should Air Ducts Be Cleaned?

There's no universal cleaning schedule that applies to every system.

How often you should clean your air ducts depends on manufacturer recommendations, what the building is used for, contamination, maintenance history and any relevant commercial requirements.

Filters and accessible grilles can need attention more often than the internal duct network.

Commercial kitchen extraction systems need particular attention because grease accumulation can create a fire hazard over time.

Cleaning intervals should be based on usage, relevant guidance and risk assessments. Industry guidance, such as TR19 Grease, may also be relevant to commercial kitchen extraction systems.
