Early Release Scheme. AKA Pet Travel Scheme. It can be complicated.
As we cannot speak on behalf of the government, you can find the DEFRA site here

If you or your vet is struggling with all this, please contact us and we will try and offer our experience
where we can. We are not liable if we, you, your vet or anyone gets it wrong, but we will try our best.

If your pet is fully Pet Schemed, we can collect your pet from an approved airport and deliver to your door or our boarding kennels in our DEFRA approved transporter. Contact us for more details.
