What is the best pet carrier to buy in the UK?
Our top pick for Pet Carrier in the UK is the Petsfit Expandable Cat Carrier Airline Approved Dual-Sided Extension 5kg Grey.
For UK cat and small dog owners who need an airline-approved carrier that also expands for longer journeys, the Petsfit Expandable Cat Carrier with dual-sided extension is the top pick — airline approval combined with the expansion panels means pets have more room during travel without triggering gate check problems.
Transporting a cat or small dog safely requires a carrier that balances containment security, ventilation, and your pet's comfort across the duration of a journey. In the UK, the Animal Welfare Act 2006 requires that animals are transported in a way that doesn't cause unnecessary suffering — a poorly ventilated, cramped, or insecure carrier fails this standard. For travel by train, the UK rail network (National Rail conditions) requires that pets must be kept in a carrier; on flights, most UK airlines including British Airways, easyJet, and Ryanair restrict live animal cabin travel, though carriers often handle connection flights via airlines that permit cabin travel on European routes. Always confirm your specific airline's requirements before purchase — dimensions vary and a non-compliant carrier at the gate is a significant inconvenience. The five picks below cover airline-approved soft-sided bags and expandable designs for longer journeys.
Buying guide
What should you look for in Pet Carrier?
1Measure your pet before buying — the carrier's interior must be large enough for your pet to stand, turn around, and lie down comfortably; this is an IATA and RSPCA welfare requirement for travel.
2Always verify dimensions directly with your airline's pet policy page — published carrier size requirements differ significantly between airlines and are updated without notice.
3Soft-sided carriers are generally preferred for cabin travel as they compress slightly to fit under aircraft seats; hard-sided carriers are better for cargo hold transport where structural integrity matters more.
4Look for escape-proof zipper locks — a panicked cat or dog can work a standard zip open; a secondary locking mechanism or snap-lock zipper significantly reduces this risk.
5A removable, washable inner mat is essential for longer journeys — travel sickness and anxiety can cause accidents, and a carrier that can be cleaned quickly reduces stress for both pet and owner.
Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.
Petsfit's expandable dual-side design is the most thoughtful carrier here for longer journeys. The ability to unzip both expansion panels at once creates a spacious rest area at the airport or hotel, while the reinforced frame prevents the sagging that plagues cheaper soft carriers. The reversible mat is a practical UK-specific touch for year-round travel.

Sherpa Original Deluxe Travel Pet Carrier Airline Approved Medium Charcoal Gray
Sherpa is the benchmark airline travel carrier, and the patented compressible spring wire frame is a design advantage that genuinely solves the under-seat fitting problem that catches out cheaper bags at check-in. If you fly with your pet regularly, the premium is justified by the peace of mind and track record. For occasional use, the Petsfit offers better value.

Editor's Note
UK pet travel regulations changed significantly with Brexit — since January 2021, taking pets from the UK to EU countries requires an Animal Health Certificate (AHC) issued by an official vet, valid for 10 days from issue and only for a single trip. This replaced the EU Pet Passport system. For domestic UK travel, cats and dogs on trains generally travel free on most National Rail services but must be kept in a carrier or on a lead. The RSPCA advises habituating pets to their carrier weeks before any trip by leaving it out as a familiar resting place — this significantly reduces travel anxiety and is particularly important for cats, who are highly environment-sensitive.
Our Take
UK pet owners spend billions a year on their animals — but the best products aren't always the priciest. The Petsfit Expandable Cat Carrier Airline Approved Dual-Sided Extension 5kg Grey is our top recommendation. The Petsfit Expandable Cat Carrier Airline Approved Dual-Sided Extension 5kg Green is worth considering if you want a step up in build quality or features. Avoid the cheapest unbranded options on Amazon UK — UK consumer protection only helps if the seller is still trading.
Questions & answers
Frequently asked questions
Can I take my cat or dog in the cabin on UK flights?
Most major UK airlines (British Airways, easyJet, Ryanair, Jet2) do not allow pets in the aircraft cabin. Exceptions exist for certain European and transatlantic carriers. Always check your specific airline's pet policy before purchasing a carrier — requirements for cabin-approved bags vary significantly by airline and route.
What size pet carrier do I need for airline travel?
Airline under-seat dimensions vary, but a common requirement is approximately 45x28x25cm or 18x11x10 inches. Your pet must be able to stand, turn, and lie down inside — a carrier that fits under the seat but is too cramped for your pet doesn't meet IATA welfare guidelines. Always measure your pet and verify the carrier dimensions against your specific airline's policy.
Do I need documentation to travel with my pet in the UK?
For domestic UK travel, no specific documentation is required beyond your dog's microchip registration and up-to-date vaccinations. For travel from the UK to EU countries, you need an Animal Health Certificate (AHC) from an official vet, valid for 10 days. For travel from the EU to the UK, different rules apply — check the UK government's official pet travel guidance at gov.uk.
