First time using Rated People, really happy.

A quick, efficient and friendly set of guys. I had them in to clean and paint my mums fence, and then she asked them to do some jet washing and further painting around the garage. All in all, great value for money. My mum was very happy with the work ethic and outcome. If she’s happy so I was very happy. We’ll definitely be calling them back in at a later date.

What does a professional cat flap installation involve?

Fitting a cat flap may seem like a straightforward task, but it requires highly precise cutting, sealing, and measuring to avoid damaging the structural integrity of your doors or windows. Standard DIY mistakes often lead to drafty gaps, ruined door cores, shattered glass panes, or compromised home security. A professional installer ensures that the opening is cut neatly to the millimeter and fully weatherproofed.

A professional cat flap installation varies heavily depending on the surface material:

  • Wooden and composite doors: The installer will measure your cat's belly height from the floor to mark the opening perfectly. They will use specialised routing tools or jigsaws to cut the core, treat any exposed timber to prevent rot, and securely seal the plastic frame.
  • uPVC and metal-skinned doors: Many modern uPVC doors feature moulded panels or hidden steel reinforcement layers. A specialist knows how to safely cut through these materials without cracking the plastic face or interfering with internal door locking mechanisms.
  • Glass doors and windows: You cannot simply cut a hole into existing toughened or double-glazed glass, doing so will instantly shatter the pane or break the airtight thermal seal. A professional glazier will take exact measurements of your existing frame, order a brand-new factory-made double-glazed unit with a pre-cut, sealed circular hole, and swap out the glass panels seamlessly.
  • Brick exterior walls: For a highly discrete installation, a specialist can core-drill directly through your brickwork and internal plasterboard, installing an insulated lining tunnel to bridge the cavity safely.

What types of cat flaps can be installed?

Microchip cat flaps

This is the most popular modern choice for homeowners. These electronic flaps read your cat’s existing, unique veterinary microchip (or a small collar tag) and unlock only for them. This entirely prevents neighborhood stray cats or local wildlife from entering your home, stealing food, or distressing your pets.

Smart / app-controlled cat flaps

The ultimate tech upgrade for pet owners, these smart doors connect to your home Wi-Fi network. They allow you to lock or unlock the flap remotely via a smartphone app, track your pet's outdoor activity habits, and even set digital curfews so the door locks automatically at dusk.

Traditional manual cat flaps

A simple, cost-effective option featuring a standard flap with a 4-way manual locking system (In Only, Out Only, Fully Open, or Fully Locked). These are highly reliable but do not offer selective entry control against stray animals.

Factors to consider when choosing an installation professional

Because a cat flap creates a physical opening to the outside world, low-quality fitting can introduce dampness, cold drafts, and security blind spots. For instance, if a cat flap is installed too close to a door handle or a lock cylinder, an intruder might be able to reach through the opening with a tool to manipulate your keys.

Choosing a vetted trade professional avoids these risks entirely. When evaluating local specialists on Rated People, look for professionals who:

  • Have verifiable experience dealing with your specific door material (especially if it involves double-glazing or composite materials).
  • Hold positive reviews praising their tidiness, particularly with clean sealants and draft-proofing.
  • Carry valid public liability insurance to protect your property during structural cutting or glazing work.

Other cat flap installation FAQ's

Can a cat flap be fitted into a double-glazed glass door?

Yes, but a specialist cannot cut directly into your existing glass pane. Instead, a professional glazier must order a brand-new, custom-made double-glazed glass unit with a pre-cut, factory-sealed hole. Once the new glass arrives, they will swap out your old panel, ensuring your home's thermal efficiency and double-glazing warranty remain completely intact.

Can you install a cat flap into a composite door?

Yes, but it requires professional precision. Composite doors are made of dense foam or solid timber cores sandwiched between rigid outer skins. If cut improperly, moisture can seep into the core, causing the door to swell and warp. A professional carpenter will seal the internal raw edges of the cut before fixing the flap to protect the door from long-term weather damage.

Will a cat flap compromise my home security or insurance policy?

Large pet doors can pose a security risk if an intruder can reach through to turn a key or lift a door latch. To stay safe and keep your insurance valid, installers recommend choosing electronic microchip flaps, placing the flap far away from lock mechanisms, or removing keys from the inside of the door lock entirely when you are away from home.
