If you’ve got an independent feline that loves its freedom and heading out on its own daily adventures, a cat flap is a must. But with that comes the stress of unwelcomed visitors finding their way into your home, whether that’s other cats from the neighbourhood, slightly less domesticated furry creatures, or worst-case scenario, skilful burglars using it to try and attain your front door keys. The solution? Microchip security cat flaps.
They will provide that safe entryway for your cat, keep your home free from pests, and give you the peace of mind you need. Plus, you can use it to track when your cat is home, especially helpful if they like to keep themselves, and some are surprisingly affordable for the added security.
What is a microchip cat flap?
A microchip cat flap will scan when your cat is nearby and recognise their microchip ID. It will then open for your cat and your cat only, and some can even register when the cat flap has been used – great for working out where your cat is or when they last popped out. In the UK, domestic cats have to be microchipped by law, so these microchip cat flaps can work for any cat owner.
We’ve shared some of the best microchip security cat flaps for your home and included some cat flap adaptors to help with the installation.

It's compatible with all common microchips and RFID collar tags, and can be installed in doors, walls, or windows - whichever suits you and your kitty! Plus its simple one-button programming function makes it easy to use and it can store the information of whopping 32 pets whilst keeping any stray animal intruders out.

Required install hole size: W165 x H171mm
Promising review: "So glad we bought this. Our cats were around a year old, so had to teach them how to use it (by literally posting them through it a few times which was quite fun!).
"We have had this for around a year, I've just changed the batteries for the first time, pleased to report it remembered the microchips. When you need your cat(s) in, EG fireworks night, just change it to only allow them in but not out, and voila, you've caught yourself some cats. Well designed, easy to use, and very convenient."
Designed especially for larger cats (and small dogs), this cat flap will keep out intruders but makes sure your cat feels very welcome. Programming up to 32 pet identities is simple with the LCD screen, plus the four-way manual lock gives you the ability to override the microchip-operated lock. The pet door unlocks only for a registered pet's microchip when they return home or for non-microchipped pets, the cat flap is also compatible with the SureFlap RFID Collar Tag (one included with the product).
Installation and use: It's easy to install into wood and can also be fitted into glass and walls. This pet door runs on 4 C cell batteries.
Required install hole size: W20.7 x H23.4cm
Promising review: "We bought this one when we could see our larger (taller) cat struggling through the smaller version. This is lovely! Really easy to register the cats and not too 'clicky'. The larger one seems happier to use it than the old one (he'd ask out instead) so all good."
PetSafe Microchip Activated Cat Flap
The best microchip cat flap for energy-efficiency
Your cat will have easy access to your home and the outside world with this cat flap which you can use with your cat's existing implanted microchip or PetSafe key fob (not included). As well as being easy to program the cat flap for up to 40 pets - perfect for animal lovers - it is also energy efficient thanks to the draught excluder and magnetic locking points for improved insulation that help protect your home from the elements. We can't rule out mucky paws though!
Installation and use: This cat flap is suitable for glass, wood, windows, and most types of PVC doors. The max shoulder width for this cat flap is 15cm. Requires four AA batteries.
Required install hole size: W22 x H23.9cm
Promising review: "I bought this in a hurry after we'd suffered a home invasion from a neighbourhood cat whilst I was out, leaving my two very much on edge.
"Installation was quick and easy, and programming it to accept the girls' microchips was as simple as holding a button down for five seconds, and then getting them to peer into the tunnel. They're cats, so that was the easiest job in the world.
"One word of advice: if, like me, you don't tend to read the instruction booklets before getting to work, please bear in mind that it's far easier to get the microchip recorded before you install the flap. Don't make my mistake in installing it and then realising that you need to take it out again. Please also bear in mind that it needs four AA batteries, but doesn't come with them."
The Ferplast swing door means your cat will have no issue using this cat flap as it magically swings open for them as they near. Guaranteed your cat will feel like royalty with this one! Available in brown or white, making it a versatile choice aesthetically, this cat flap is not only equipped with the usual microchip recognition software, but it also comes with a microchip collar in case your cat hasn't been chipped yet or there's an issue with their existing microchip. The cat flap can record up to 32 microchips and is easy to use.
Installation and use: The measurements given should help you when installing this door. It's lockable as either an exit or entrance, giving you full control. Requires six AA batteries.

SureFlap Microchip Cat Flap Connect and Hub Bundle
The best app controlled microchip cat flap
If you want an advanced microchip cat flap with all the bells and whistles, then this is it. It's app-controlled, so you will benefit from all the features of a typical microchip cat flap, plus a lot more. You'll get notifications on your phone when your cat uses the cat door, and it monitors your pet's activity and behaviour. The DualScan technology even lets you set exit permissions for each cat.
Installation and use: Both the app and flap itself are easy to install and use. Four AA batteries are required.
Measurements: 21 x 20.8 x 15cm
Promising review: "I bought this cat flap to stop unauthorised entry into the house of other cats. As this replaced a normal Staywell cat flap I found the fitting very easy as the hole required in the door was the same size. After inserting batteries and scanning the two cats' microchips it was all systems go. The cats took a little while to get used to the cat flap as they have to go head first so the sensors read the microchip and then unlock the cat flap. This only took about 2 days and now they seem very happy to use it. The app on my phone shows when they have been in or out which gives a great idea of their movements."
For those of you who want added control to protect your pet, this microchip cat flap is ideal. Your cat will have the independence they want during the day, but you can set a night-time curfew with the programmable timer function so you can both sleep soundly. It has an easy-to-use LCD screen, and while it's not as fancy as the Sureflap, the Cat Mate Elite still lets you monitor your cat's movements showing the entry and exit lock status, location, and time since the last use of the flap for up to three cats.
Installation and use: Can be installed into single or double glazing, plus wood, wall, and metal. It also requires four AA batteries.
Measurements: 24.77 x 14.48 x 26.67cm
Promising review: "This cat flap which only lets my cat in using its chips Is great. It was easy to install and program and definitely less traumatic for the kitty. Our old cat flap gave you 20 seconds to catch the cat, scan it like a grocery item, and then press the button to accept. This model gives you plenty of time, just let the cat walk through the hole, and hey presto all done and a quick press to accept.
"Definitely one of the easier models we've purchased for our fur babies to have access to the house without stray intrusions. I would definitely recommend this product."
SureFlap Dual Scan Microchip Cat Flap
The best microchip cat flap for a multi-pet home
The SureFlap Dual Scan Microchip Cat Flap is very similar to the SureFlap Microchip Cat Flap with microchip or RFID collar tag identification and the fact it can be programmed for up to 32 cats. However, this cat flap is equipped with DualScan Technology so you can set entry and exit permissions for your different animals with each pet being learned at just the push of a button. There's also a safety mode so any indoor-only pets can gain entry if they escape through an open door or window, making sure no family members get stuck outdoors.
Installation and use: Can be installed in wood, uPVC, glass, and walls. Requires four AA batteries.
Required install hole size: W165 x H171mm
Promising review: "I bought this in order to let 1 of my cats outside, without having to open the door for him. My other cat is an indoor-only cat, so we have programmed it to let him in only (in case he ever gets out) and our outdoor cat in and out. With bonfire night coming up I am pleased there is a manual lock button as well.
"The flap does make a loud clicking noise as the flap unlocks. My outdoor cat is a bit of a scaredy-cat, and it took him quite a while to figure out that it wasn’t trying to bite his head off, and he could actually go through it. We used tuna to entice him through, and now he has no problems with it and uses it by himself.
"We did not fit it ourselves, we had a new door fitted, and they fitted it into the door before they came, so unsure of how easy it was to fit. They had no issues with it. Awesome that it takes regular-size batteries too, but we’ll see how long they last. Overall very happy with the product, and would recommend."
Microchip cat flap adaptors
A cat flap adaptor is often required or recommended for you to mount your cat flap into walls, windows, and certain door types. Not only does it help seal and secure the fitting of your microchip cat flap, but it also gives a neat finish.
How do you put in a microchip cat flap?
If you're putting your cat flap into a glass door or wall, we'd recommend hiring a professional to fit the installation as you'll require specialist tools. However, you can install a cat flap into a wooden or plastic surface of your own accord using a drill and jigsaw.
First of all, you'll need to measure the ideal position of your cat flap so your cat can easily hop through. It should be as high as your cat's legs. Next, using the provided template or cat flap frame, draw the size of the cat flap hole onto your door, before drilling through each corner and connecting the dots using your jigsaw blade.
