• EU exit

    Please note that, in the event of UK participation in EASA and mutual recognition of licences and certificates ceasing, some CAA website content and application forms may continue to carry the EASA logo or reference the EU or EASA rather than the UK CAA in the short term. 

    These will be updated in due course following the outcome of the transition period negotiations on the long-term aviation relationship between the UK and the EU.  In the meantime, the guidance provided and the application forms accessed via the CAA website portal will continue to be valid.

  • Aircraft noise certification levels approved by EASA up to and including 31 December 2020 are considered to be also approved by UK CAA. Noise certification levels approved by EASA since then are not automatically approved by UK CAA.

    Lists of CAA approved noise certification levels can be found here:

  • For any configuration of aircraft for which a UK noise certificate is required and which is not on the list of approved noise certification levels please contact CAA on certnoise@caa.co.uk. TC/STC holders wanting CAA noise certification for an aircraft configuration not approved by CAA will need to formally apply to UK CAA for approval by using the following links, Guidance on Type Design Approval for the issue of a TC or RTC and  Guidance on minor and major changes or repairs

    CAA will continue to issue noise certificates to aircraft on the UK civil aircraft register. Note that not every aircraft on the UK Register is obliged to have a Noise Certificate. For example there is no legislation requiring noise certificates for some older aircraft and Permit to Fly aircraft. Note also that microlight aeroplanes are now exempt from the need to be issued with a noise certificate (Official Record Series 4, No. 1502).

    Applications for a noise certificate

    Note that an application for a noise certificate is not required when you are also applying for a Certificate of Airworthiness.


    The aircraft must be fully registered in the UK prior to the issue of any Noise Certificate.

    How much does it cost?

    Full details of all prices are available in the Scheme of Charges.

    How long will it take for my application to be processed?

    The Noise Certificate will be issued within 20 working days, unless an investigation is needed to establish the aircraft’s compliance with the noise certification requirements.

    1. You will receive an automated email receipt following submission of the online application form
    2. The application will be passed to a Surveyor for review
    3. Further information to substantiate the application may be required
      (this may include the request of further documentation or to arrange a Noise Test - the Surveyor will usually be the contact for this)
    4. A Noise Certificate will be issued once the Surveyor is satisfied that all necessary paperwork is in order and that noise levels are acceptable
