Dogs which have been trained by an organisation that is a member of International Guide Dog Federation (IGDF) or Assistance Dogs International (ADI)  will be recognised as assistance dogs. Dogs which have received equivalent training or testing may also be recognised by your airline.

Unrecognised assistance animals are those that do not meet the criteria listed above. They are subject to a checking fee of £410 which the owner must pay direct to us.

We need to check your assistance dog's paperwork in advance to ensure compliance with PETS.

We require the paperwork a minimum of 72 hours prior to departure, however some airlines require the pre-approval status up to seven days before departure. Please check with your airline directly.

When we have checked your paperwork and taken payment (if applicable) we will issue your pre-approval letter. You should forward your pre-approval letter to your chosen airline and show it to the check-in staff.

Your pre-approval letter will be emailed to you shortly after payment (if applicable).

​Please keep all the original paperwork with you ready to show HARC staff when you disembark the plane; if in the unlikley event that HARC staff are not there to meet you please seek assistance from the airport staff as it is a legal obligation to have all documents checked on arrival into the UK. Your dog's microchip and original paperwork will be checked which shouldn't take longer than five minutes. When finished we will issue a certificate which you must present at immigration.
