Best microchip cat flaps in 2026: 10 UK picks
What are the best microchip cat flaps in 2026?
Buy a SureFlap Microchip Cat Flap for most UK homes — it reads existing chips reliably and spare parts are easy to get years later. Pay up for the Connect version only if you want app alerts and curfews. Whatever you fit, measure your door or wall thickness first, because tunnel extensions are the step most people forget.

What actually decides this purchase?
Welfare first: no shock, prong or spray. Washable covers, escape-proof clips and spare parts beat Amazon “bestseller” aversive kit.

When is the cheaper option the right buy?

The bottom line
Buy a SureFlap Microchip Cat Flap for most UK homes — it reads existing chips reliably and spare parts are easy to get years later. Pay up for the Connect version only if you want app alerts and curfews. Whatever you fit, measure your door or wall thickness first, because tunnel extensions are the step most people forget. Start with Sure Petcare Microchip Cat Flap Connect unless a badge further down matches your job more closely. If none of these survive the values filter for your household, skip the category rather than buying a disposable extra.
