Can I Put A Cat Flap In A Composite Door?

Composite doors offer many benefits over wooden doors, but you might be wondering whether you can install a cat flap in a composite door or not, as this could be a severe deal-breaker for many pet parents.

Thankfully, at UK Composite Doors, we can provide you with composite doors with cat flaps installed. We ask that you provide us with the cat flap, and then we will cut the opening on site to fit shortly after.

If you would like to get a composite door with a cat flap, design and order your door online below. Please note if your door is supply only, you must let us know your measurements, and then we will cut the hole at our factory. For supply and fit, the hole will be cut on-site.

Purchasing A Composite Door With A Cat Flap

If you haven't purchased your composite doors yet, then you should consider buying composite doors that already have a cat flap fitted, as this will save you a lot of time and money. This also applies to dog flaps, as purchasing a composite door with a dog flap will always be better.

These doors come out of the factory extremely sturdy and tough, but making DIY alterations to them will significantly affect their strength, so you should keep this in mind before you break out the power tools!

Retrofitting A Cat Flap To A Composite Door

While it is certainly not recommended, it is definitely possible to retrofit a cat flap to a composite door.

Composite doors feature solid hardwood timber cores, and, as we have mentioned above, if you cut into them to make room for a cat flap, you will make your door less secure and will also be voiding your warranty.

This will still be the case if you decide to hire a professional to cut a hole for your cat flap and install it; however, it is still a better idea to order your pet doors from a company that offers installation, especially if you don't have experience with DIY projects.

Where Else Can I Install Cat Flaps?

If you don't like the idea of voiding your composite door's warranty, but you have already purchased a door without a pet flap, consider installing a cat flap in another area of your house.

Many pet parents choose to install cat flaps on their patio doors, conservatories, and even on the external walls of their homes - although make sure that installing a cat flap in these areas won't void any other warranties.


Can I install a cat flap in a glass door?

Some of our composite door designs here at UK Composite Doors feature glass panels, so this is a valid question.

Thankfully, the design of your door will not have much effect on whether or not you can install cat flaps, so long as the glass panels aren't in the way.

Will a cat flap affect my home insurance policy?

Before cutting holes in your composite door, check with your insurance provider whether installing a cat flap will void your home insurance policy.

Some providers see cat flaps as negatively impacting the structural integrity of your doors and, therefore, your home security.
