Get your disinfectant approved by Defra

Find out about the process and costs to apply for Defra disinfectant approval.

If there is an outbreak of a notifiable animal or zoonotic disease, only Defra approved disinfectants can be used for cleaning and disinfecting hard surfaces like buildings, farm equipment, crates, and vehicles.

You are breaking the law if you market and sell as Defra approved a disinfectant that has not been tested and listed as approved.

To get your product approved by Defra it must:


This scheme is underpinned by the The Diseases of Animals (Approved Disinfectants) (England) Order 2007

The costs are set out in The Diseases of Animals (Approved Disinfectants) (Fees and Amendment) (England) Order 2011

Download details of the APHA efficacy methodologies (PDF, 348KB, 6 pages) for more information.

Submit samples

If your product is accepted for testing you will be told where to send your samples and your purchase order for the tests you want.

See the application form for instructions on how to submit samples and packaging labels. You must not send any samples until APHA asks you to do so, or make a payment to APHA until you have received an invoice raised for your purchase order..

Approval testing fees

You must pay in advance for testing, but should wait until you know your product has been accepted for testing. You can pay by bank transfer, credit card or by cheque once APHA has sent you an invoice for your purchase order.

UK companies will have to pay VAT on the fees shown in the following table. Companies outside the UK do not have to pay VAT.

Approval tests Fees per test (£)
Foot and mouth disease 1,920
Swine vesicular disease 1,920
Diseases of poultry and the avian influenza and influenza of avian origin in mammals:  
- single dilution test 1,040

General Orders:

You should receive the results within 12 weeks of submitting your samples. This may take longer due to urgent statutory work (eg responding to a disease outbreak).

Product approval

You will get a ‘conditions of approval’ letter if your product passes the APHA tests.

This letter will include a text box with some wording specific to your disinfectant and you must add this to your label. Email disinfectants@apha.gsi, for more information about this wording.

You need to sign and return the letter with a copy of your prepared label to Defra Disinfectants Approvals Administration at APHA before your product can be added to the list. Your product is usually listed within 5 working days of APHA receiving your signed letter.

You can only label, market and sell your product as Defra approved when it is on the approved list. You can find the complete list of Defra approved disinfectants on the approved disinfectants list.

Approval lasts for 2 years. There is a renewal procedure and conditions to extend approval. There is no fee and you may not need to submit samples but APHA will ask you to provide some information.

Product changes

You must tell APHA if you change the formula of your approved disinfectant, or if any details you originally supplied have changed. APHA and Defra may decide to retest a product to make sure it is still effective. You will have to pay for these tests.

Product check tests

APHA runs random check tests on approved disinfectants. You will only know if your product has been chosen for check testing if it fails the tests.

You will be told the test results as soon as possible. Your product may be suspended from the list. You can re-submit the product for testing for which you have to pay the full test fees.
