Top 5 Best Microchip Cat Flaps – UK Comparisons, Buyer Guide & Reviews

If you are a cat parent who gives your cat the freedom to explore the outdoors, then you know you have to make a kitty door for them to access the house. However, one major issue with a cat flap without a key is that other than your cat, other stray cats in your area will use it to come in and go out as they please leaving a mess behind. Most tray cats will do this at night so you might not even realise there visiting, eating your cat’s food etc. This is where microchip cat flaps come in.

Microchip cat flaps allow your microchipped cat to come in and go out as they please. This keeps any unwanted pets out of your house while allowing your cat unlimited access to the house so that they can shelter any time they need to and explore the surroundings when they feel like it.

SureFlap Microchip Cat Flap Connect with Hub
If you are looking for something a bit more advanced, our Runner-up the SureFlap microchip cat flap connected with a hub will be an ideal choice for you. It’s operated via a mobile app that allows you to lock it or unlock it remotely from anywhere but you can still program it through the cat flap two as you do with other models. We like that you will get notified when your cat comes and leaves and that you can set curfew hours for your cats, and you can also decide which cats can leave and which ones stay in the house. It is battery operated, running on 4AA batteries that can last up to 6 months so not as long as the non-hub versions which tend to last for around 12 months.

Best Microchip Cat Flaps Reviews

1. SureFlap Microchip Cat Flap

BEST PICK

Buy on Amazon.co.uk 

SureFlap Microchip Cat Flap

This is one of the best microchip cat flaps on the market if you are looking for a permanent key for your beloved cat while keeping intruder cats away. The flap works with cat microchips, as well as RFID cat collars, which unlock the flap when your cat approaches. This way, your cat can come in and go out as they need without you getting involved. At the same time, it also keeps other cats out. Whats we will say is this model is as basic as microchip cat flaps get with all the essential simple feature. So there no timer, its doent scan on exit any only let certain cats out and there no fancy app. So what can it do you?

Its obviously only lets your cats in or out but there is also a manual lock on the flap for when you need to keep your cat from leaving or coming into the house. This can be set to in and out; out only; in only; no entry or exit but this cannot be done automatically via the scanned microchip as some cat flaps can.

This flap can be installed on walls, windows, and doors, depending on where you want to install it. You will, however, need a round flap adaptor if you are installing it on glass and a tunnel extender if you want to install it on a wall. You can buy these accessories with the flap.

The flap uses 4 AA batteries that last for as long as a whole year before you have to replace them, this is longer than some of the more advanced models as they only last around 6 months so it wins a few extra points there. Because this flap uses batteries and requires no wired connection, you can install it anywhere which is obviously another advantage over wired models.

It’s easy to program with just a push of a button and a treat to encourage them to go through the cat flap to set the microchip setting. You can program up to 32 cats to use the same flap, which makes it suitable for you if you have multiple cats in your house.

When you want to keep your cats in the house or out, there is a manual 4-way manual lock on the flap that overrides the microchip access. This way, your beloved felines are restricted to the house when there is bad weather. What you can’t do is set it to only let certain cats leave.

 The flap measures 16.5 x 17.1cm on the inside, and you will need a hole measuring 21 x 21cm for the installation. If you are installing it on a glass surface, you will need a 21.2 centimeters diameter hole and we recommend getting a professional to cut the hole in glass.

Finally, It comes with a 3-year warranty, which reassures you that you will be making a worthy investment.

Pros

  • A reliable and affordable model.
  • It’s easy to program, and you can program up to 32 cats.
  • Manual override to set in and out; out only; in only; no entry or exit.
  • No wired connection, the flap uses 4 AA batteries that last for up to a year.
  • Can be installed on a window, wall, or the door.
  • Works with both microchips and RFID collars.
  • It can be installed anywhere since it’s not wired.
  • Allows your cat to access the house at any time.
  • It comes with a 3-year warranty.

Cons

  • Cannot set it so only certain cats can leave.

Why do we recommend it?

If you are looking for a reliable microchip cat flap with all the basic but essential features, this is one of the best ones you will find on the market currently. It’s pretty easy to program, and you could program up to 32 pets into one flap. It is battery-powered, which means you can install it anywhere because there are no wires needed. The flap works with both microchips and RFID collars.

Overall, this cat flap is well-reviewed on Amazon with thousands of positive reviews. You will have peace of mind knowing that your cat can always come and go as they need to. The only real downside is that if you want to let only certain cats out but keep on in, this cannot be set. They either all can leave or all have to stay in. You would need a mode that also has exit scans.

You will get notified when your cat comes in or leaves the house, you can also now set different curfew times for different cats as they have now updated the software, this is something you could previously do so nice to see this feature has now been added.

The app also allows you to monitor their behaviour and notice if they deviate from their routine. Its does this as it knows how many hours your cats usually spend outdoors and if they are suddenly staying in much longer. What you cannot do with the app is set it so only certain cats can come in or out although you can set this manually through the cat flap.

It’s easy to program, and you can program up to 32 pets on the same flap, which makes it suitable if you have multiple cats in your house, not sure how many people have 32 cats but if you have a need for it, its there. The app also allows you to choose which cat can go out.

The flap is battery powered and needs no wired connection, which means you can connect it anywhere on a window, a door, or on a wall. It uses four AA batteries, which you have to buy separately. The batteries can last around six months so this is six months less than then our Best Pick but it does have many more features.

  • Allows you to set curfew hours for the cats, you can now also set different times for individual cats.

  • You can remotely unlock or lock the flap remotely from anywhere.

Cons

It uses a cat’s microchip and RFID cat collars to give your cats unlimited access to your home. The best thing about this cat flap is that you can lock or unlock it remotely from anywhere, and you can also decide which cats go out and which ones don’t all within the app, this is a feature that was only recently added. You can also set curfew hours for your cats.

Overall this is a great model with lots of useful features, if you need a little more control over your cats, perhaps remotely, this is well worth considering. No other model has more features but most are not as expensive either.

Like our previous two picks, this flap needs no wires to connect, which means you can install it anywhere. You can install it on a wall, a window, or a door. If you are installing the flap on a wall, you will need to get a tunnel extender, if, on glass, you will need the PetSafe cat flap adaptor. All these accessories are available; make sure you get what you need for the installation.

If you have a large cat breed, this flap is suitable as it can be used by cats weighing up to 8kgs, now this covers most cats but some very large cats might find it a tight fit. It’s also easy to program with a simple push of a button which is always a big plus as some models are simply just to overcomplicated.

The flap uses 4 AA batteries, which can last for up to 12 months, and there is an LED notification when the batteries are running low so that you are never caught unprepared. You will need to buy the batteries separately when you buy the flap and we recommend some good quality Duracell batteries.

Buyer’s guide: considerations for the best microchip cat flaps

There are lots of microchip cat flaps on the market, and when you are looking for the best one, it can be frustrating sifting through all those choices, especially as most seem to have the same features.

It gets a little easier when you know what to look for. In this buyer’s guide, we will be telling you everything you need to know to get the best one on the market currently. Here is what to keep in mind.

Compatibility

Before buying a microchip flap for your cat, check that the flap is compatible with your cat’s microchip if they are already microchipped. This way, you will have no issues programing your cat to the microchip. Some cat flaps are no compatible with the newer 10 digits, and lettered microchips.

Dimensions

Before buying a flap, make sure that your cat would fit through the flap. Most cat flaps are a standard size, but just make sure that your cat would fit through, especially if they are a large cat.

Microchip cat flap installed in standard door

Also, think about the installation. Some flaps will need extra accessories to install on certain surfaces, like a tunnel extender for the wall or a flap adapter for the glass. Most models have these but also check there in stock too.

How many cats can you program to the flap?

If you have multiple cats in your home, look at how many cats you can program to the cat flap. Most cat flaps will support anywhere between 20 to 40 cats.

Insulation

Some cat flaps leave your home exposed to the elements when installed such that cold winds go through the flap edges into your house. Check that the flap you are buying is insulated. All the models in this review are generally insulation and this is not an issue.

Extra features

Some models come with extra features such as the ability to only let certain cats out while keeping other cats in. This may be especially important if you have an indoor cat and one that is allowed outdoors. Not all models have this feature.

Vet and night mode

Some models even come with night and vet model and go as far as only letting certain cats out, this is handy if you have a cat that needs to go to the vet so want to keep that cat in while letting the other cats out. Night mode usually uses a sensor to automatically stop your cats going outdoors after dark, again this can sometimes be set to only work with a particular cat if needed.

Wifi and Apps

Finally, as we saw with our Runner-up, some models even now have wifi and connect to apps, this is great for controlling your cat flap remotely if needed.


In conclusion,

Every cat should be free to explore the outdoors, but also be able to access your home for shelter for food, and security. You could create a kitty door for them but this will be an invitation to all the strays, to come in and make a mess of your house. This is the problem with normal cat flaps. They let any cat in and out as they have no what to identify an individual cat.

This is where a microchip cat flap comes in handy. A microchip cat flap allows your cat exclusive access to your house while keeping all intruder cats away at the same time. We have listed the 6 best ones on the market, and we hope you find your cat’s next flap on this list.

Our best pick, the SureFlap Microchip Cat Flap is a great place to start looking. It comes with a 3-year warranty, you can program up to 32 cats on one flap. This flap is powered by 4AA batteries that can last up to a year. It’s simple to program and can be installed anywhere in the house since it’s not wired.
