How we compared · 14 sources, checked 21 October 2026Show

What we did

compared the six microchip cat flaps with a current UK price on 21 October 2026, using the makers' UK pages and zooplus UK for price, opening size, chips read, battery life, number of cats stored and glass fitting. Picks are labelled by one measurable fact (price, timer, capacity, size).

What we did not do

fit or use these flaps, or measure how reliably they read a chip. Reliability can depend on where your cat's chip sits and the door material, which only the maker's compatibility check or a trial fitting can tell you.

See price at zooplusAd£204.99 with Hub, checked 21 Oct 2026. Sure Petcare UK: £140 flap + £85 Hub (£205 as a set)

Is a microchip cat flap worth it?

A microchip cat flap is worth it if neighbouring cats come in, or if you do not want your cat to wear a collar. International Cat Caresays that until recently the only way to make a flap selective was a magnetic or electronic key on the collar, and that flaps “activated by your cat’s microchip” now allow selective entry without one. It lists collar injuries including a front leg caught through the collar and strangulation, and advises a snap-open collar if your cat wears one.

Your cat probably has a chip already: in England cats must be microchipped and registered by 20 weeks old, with a fine of up to £500 (GOV.UK). Budget for the flap alongside the other costs in our cost of owning a cat guide and the new kitten checklist.

Do microchip cat flaps work?

The makers say they keep other animals out: Sure Petcare says its flap “prevents intruder animals entering your home”, and PetSafe that it “prevents strange cats or other animals from entering your home uninvited”. What decides whether a microchip cat flap works for your cat is the chip it can read:

  • SureFlap flaps read 9, 10 and 15-digit chips (zooplus listing).
  • PetSafe reads European FDX-B 15-digit chips.
  • Cat Mate Elite reads 15-digit chips or its own I.D. Disc.

If your cat's chip is not read, each maker sells an RFID collar tag instead. Most flaps read only on the way in, so any cat can leave; the SureFlap DualScan reads both ways and lets you keep a chosen cat indoors.

Can you fit a microchip cat flap in a glass door?

Yes, all six microchip cat flaps here can go in glass, but none fits straight into an existing pane:

What you need

  • A round hole in the glass. Sure Petcare gives 212 mm as the optimum for its cat flaps (up to 260 mm with the £13.50 Cat Flap Mounting Adaptor), and 294–320 mm for the Pet Door (£24 adaptor).
  • A glazier. zooplus says the pane usually has to be replaced with one that has a pre-cut hole, that this needs a professional glazier, and that DIY is not recommended.
  • Double glazing is possible with the SureFlap adaptor and the PetSafe adaptor; Cat Mate lists single and multiple glazing for the Elite.

We found no published glazier price to quote, so ask for a quote for the new pane with the hole before you buy the flap.

How much does a microchip cat flap cost?

On 21 October 2026, the six flaps cost £69.99 to £120, or £204.99 for the SureFlap Connect with its Hub. Add £13.50 or £24 for a glass adaptor, £9 per 50 mm tunnel extender for a thick wall, and £10.50 for two SureFlap collar tags if you need them. If you are also choosing a feeder, our automatic cat feeder comparison covers microchip feeders from the same makers.

More cat kit: cat water fountains, litter trays and the cat tech hub. If a cat comes home injured after a fight, see our cat insurance guide, and if you are worried, contact your vet.

Others we looked at

  • SureFlap Microchip Pet Door Connect: the app version of the larger door, from £155 (£213.49 with Hub at zooplus). Left out to keep one Connect model; it has the same app features as the cat flap version.
  • Manual and magnetic-key flaps: not compared here: this page covers only flaps that read a microchip. A manual four-way flap such as the Ferplast Swing 11 was £43.19 at zooplus on 21 October 2026.

Frequently asked questions

Is it worth getting a microchip cat flap?

It is worth it if you want to keep other cats out without your cat wearing a collar. International Cat Care says microchip flaps allow selective entry without a collar, and it lists collar injuries such as a leg caught through the collar. The flaps we compared cost £69.99 to £120, or £204.99 for the app version with its Hub, on 21 October 2026.

Do microchip cat flaps work both ways?

Most read the chip only on the way in: Sure Petcare says the standard Microchip Cat Flap's reader is on the outside, so any animal can exit. The SureFlap DualScan reads in both directions, so you can choose which cats may go out.

How much are microchip cat flaps?

From £69.99 (SureFlap Microchip Cat Flap at zooplus) to £120 (SureFlap Microchip Pet Door), checked 21 October 2026. The app-controlled SureFlap Connect was £204.99 with the Hub it needs. Fitting in glass adds a mounting adaptor (£13.50 or £24 at Sure Petcare) plus a glazier's charge.

Which microchip cat flap is best for a large cat?

Of the six we compared, the SureFlap Microchip Pet Door has the largest opening at 178 × 170 mm and is described as "designed for large cats and small dogs". PetSafe says its cat flap suits cats up to 8 kg with shoulders no wider than 15 cm.

Can you use a microchip cat flap without batteries?

All six flaps here run on batteries (AA, or C for the Pet Door). Sure Petcare says its flaps remember registered cats when the batteries are removed, and each has a low-battery light.

Does a microchip cat flap work with a collar tag?

Yes. Each maker sells an RFID collar tag for cats whose chip the flap cannot read or cats without a chip: SureFlap tags cost £10.50 for two at Sure Petcare, and Cat Mate uses its own I.D. Disc.
