People searching for the cost of a TR19 certificate are usually asking one of two questions: what does it cost to have my extract system cleaned and certified, or can I pay for the certificate on its own? The short answer is that the certificate has no separate price. It is issued as the final step of a clean carried out to TR19 Grease, or as the conclusion of an inspection that measures the system and reports on its condition. What you pay for is the work and the measurement; the document comes with it.
Typical prices in 2026
The figures below are broad ranges drawn from the quotes our partner contractors provide across the UK. Every system is different, so treat them as a guide to what is reasonable rather than a price list.
| Scenario | Typical cost | Certificate issued |
|---|---|---|
| Inspection and TR19 report only, no cleaning | £150 to £350 | Condition report with readings; compliance certificate only if the system is already within limits |
| Single canopy, short duct run, small kitchen | £300 to £600 | Yes, on completion |
| Medium restaurant or pub with a longer duct run | £500 to £900 | Yes, on completion |
| Hotel, care home or multi-canopy site | £900 to £2,000 or more | Yes, one report covering each system |
The kitchen extract cleaning cost guide goes deeper into what pushes a job towards the top or bottom of each range.
What the price should include
A quote that leads to a valid certificate covers more than labour. It includes the pre-clean survey and grease-depth readings, cleaning of the canopy, plenum, filters, ductwork, fan and discharge, post-clean readings at the same points, photographs before and after at every access point, safe disposal of the grease removed, and the written report with a next-due date. If a quote is silent on any of those, ask before accepting it. The most common omission is the ductwork beyond the first bend, and a certificate that quietly excludes it will not satisfy a loss adjuster.
What costs extra
- Access panels. Where a duct run has no openings, panels must be cut in before it can be cleaned. They are a one-off cost that makes every future clean cheaper and faster.
- Heavy first cleans. A system that has gone years without attention needs scraping as well as degreasing, and the contractor will price for the extra hours.
- Roof access. A fan or discharge that needs a tower or powered platform to reach adds equipment hire.
- Out-of-hours work. Most cleans happen overnight anyway, but some contractors add a premium for Sunday or bank holiday visits.
- Filter replacement. Damaged baffle filters are replaced at cost; see filter cleaning and replacement.
When an inspection-only report is the right buy
Paying £150 to £350 for an inspection and report without a clean makes sense in a handful of situations. You are buying or leasing premises and want to know what you are inheriting. A landlord or insurer has asked for evidence and the last clean was recent enough that the system may still be within limits. You run several sites and want a consistent baseline before setting a contract schedule. Or a kitchen sits between usage bands and you want measured readings to justify a six-month rather than three-month interval. In each case the report tells you where you stand, and if cleaning is needed the inspection fee is often offset against the clean when the same contractor does both.
Certificate-only offers to avoid
Occasionally a business is offered a certificate for a low fee without anyone measuring the ductwork. A document produced that way is not a TR19 certificate in any meaningful sense, because TR19 Grease requires verification by measurement and photographic evidence. If it is ever tested by an insurer after a fire, it will fail, and the money saved will look very small beside a reduced claim. The choosing a contractor guide lists the questions that expose this kind of offer.
Budgeting over a year
Because validity follows the frequency table, with cleans every three months for heavy use, six for moderate and twelve for light, the annual cost depends on the usage band. A heavy-use kitchen on quarterly cleans will have four certificates a year; a moderate-use restaurant two; a light-use school or office kitchen one. Contractors generally offer better per-visit pricing for a scheduled contract than for one-off bookings, and the insurer sees an unbroken record rather than a series of gaps.

Frequently asked questions
Can I buy a TR19 certificate on its own?
Not legitimately. The certificate records that a system has been measured and either found within limits or cleaned back to them, so it cannot exist without an inspection or a clean behind it. The cheapest route to a valid document is an inspection-only report, which costs typically £150 to £350 and confirms compliance if the readings allow.
Why does the same kitchen get different quotes from different contractors?
Quotes vary because contractors make different assumptions about the length and accessibility of the ductwork, how many access panels are needed and how heavy the deposits will be. The way to compare quotes fairly is to ask each contractor to confirm in writing that the price covers the whole system to discharge, with readings and photographs. A lower figure that excludes the ductwork is not cheaper.
Is the certificate cheaper if I am on a contract?
Usually the per-visit price is lower on a scheduled contract, because the contractor can plan the visit, knows the system and has the access panels already in place from the first clean. The certificate itself is not priced separately either way; the saving comes from the work being more predictable.
Does the price include VAT?
Ranges in this guide are indicative and quotes from contractors are normally given excluding VAT, which is added at the standard rate for VAT-registered businesses. Always check the quote states whether VAT is included so that comparisons between contractors are like for like.
