How Much Does Commercial Kitchen Extract Cleaning Cost?

One of the most common questions from commercial kitchen operators is a straightforward one: how much does kitchen extract cleaning actually cost? The honest answer is that it varies — sometimes significantly — depending on a range of factors specific to your kitchen and extract system. This guide explains what drives pricing and what you should expect when getting a quote.

What Affects the Cost of Kitchen Extract Cleaning?

1. Kitchen Size and Canopy Area

The most immediate factor is the size of the extraction canopy itself. A small café with a single 1.5-metre canopy over a domestic-scale commercial hob will cost considerably less to clean than a hotel kitchen running multiple large canopies serving a 200-cover restaurant and function suite. Contractors price partly on the area of surfaces that need to be cleaned and degreased.

2. Duct Length and Configuration

The ductwork connecting your canopy to the external extract point can vary from a few metres to tens of metres, and may include bends, risers through multiple floors, horizontal runs, and access hatches. Longer duct runs take more time, require more chemical product and may need additional operatives. Complex configurations — particularly in older buildings where the extract route is indirect — increase costs further.

3. Access Points and Inspection Hatches

Professional extract cleaning to TR19 standards requires adequate access hatches throughout the duct run. If your system has limited access points, contractors may need to create additional hatches to clean the full system. This adds time and materials cost but is essential for a thorough and properly documented clean.

4. Cooking Type and Grease Loading

What you cook matters enormously. A fish and chip shop running multiple large fryers continuously produces far more grease than a sandwich bar with a single panini grill. TR19 guidance classifies kitchens by use intensity, and heavy-use kitchens — those with high-volume frying, chargrilling, solid fuel cooking, or extended service hours — typically accumulate grease far faster and require more frequent cleaning. This can affect both the time needed per clean and the cleaning frequency you'll require over a year.

5. Time Since Last Professional Clean

If your extract system has not been professionally cleaned for an extended period — or ever — the initial clean will take significantly longer than a maintenance clean on a regularly serviced system. Hardened or thick grease deposits require more chemical treatment, longer dwell times and more manual effort. A system that has had regular six-monthly cleans will be far quicker to service than one that has not been touched in three years.

6. Fan Condition and Motor Type

Cleaning the extract fan, motor housing and impeller blades is often included as part of a full system clean, but the complexity varies. Roof-mounted fans, high-level motor units and certain fan configurations require more time to access and clean safely.

7. Filter Replacement

Baffle filters and mesh filters typically come with cleaning included, but some services may separately quote for replacement filters where baffle units are damaged or mesh filters have reached end of life. Clarify with your contractor whether filter replacement is included or quoted separately.

What About Cost per Clean vs. Annual Cost?

Because cleaning frequency varies with cooking intensity, it is worth thinking about total annual cost rather than just the cost of a single clean. A takeaway paying a moderate price per clean but requiring quarterly visits will spend more annually than a small café on an annual schedule — but the higher total reflects the genuine grease loading and risk profile of the operation.

Many operators find it useful to think of extract cleaning as a routine utility cost of operating a commercial kitchen, similar to servicing kitchen equipment or waste management contracts. The cost is predictable once you have an appropriate maintenance schedule in place.

What Does the Price Include?

When comparing quotes, check exactly what each includes:

• —Canopy cleaning — internal and external surfaces, filter frames, plenums
• —Duct cleaning — the full duct run to external discharge, not just the visible section
• —Fan cleaning — impeller, motor housing, discharge grille
• —Filter cleaning or replacement — whether included or billed separately
• —Post-clean report — the documentation you need for insurance and compliance records

A quote that excludes post-clean documentation or only cleans part of the system is not offering a comparable service to one that covers the full system and produces compliant certification.

Should I Always Choose the Cheapest Quote?

Not necessarily. The single most important thing your extract cleaning contractor produces — beyond the physical cleaning itself — is the post-clean report. This document is what you show to your insurer, your fire risk assessor and environmental health if they ask for evidence of compliance.

A cheap clean with no documentation, or documentation that does not meet the standards expected by your insurer, may leave you no better protected than not having had a clean at all. In the event of a kitchen fire, your insurer's claims department will look closely at what cleaning was done, when and by whom.

This does not mean you should always pay the highest price — but it does mean you should always verify that any contractor you use produces compliant post-clean certification and carries appropriate insurance.
