Labour Costs and Time Frames

Let’s now discuss the labour costs of each pet installation job. In this section, we’ll also look at factors that shape the labour price and timeframes.

Here’s another thing...

On average, a tradesperson will charge around £40 to £50 per hour to install a pet flap. This, along with the supply costs, will add up to the total cost of a pet flap.

Breakdown of time frames:

  • Installing a small pet flap - 1 to 2 hours
  • Installing a medium pet flap - 1 to 3 hours
  • Installing a large pet flap - 2 to 4 hours

Labour Cost and time frame factors:

  • Size and type of pet flap
  • Type of door/wall
  • Ease of access
  • State of the work area

Cost Affecting Factors of Installing a Pet Flap

We’ll now take a closer look at the factors that shape the cost of paying a professional to fit a pet flap. Let’s explore various cost factors, such as the type of door and ease of access.

Size of Pet Flap

Of course, the larger the pet flap, the more it will cost to buy. In addition, a larger pet flap would probably cost more to install, given that the labour times are likely to be extended as a result.

Type of Door

It can sometimes prove easier to fit a cat flap or dog flap to some types of doors over others. However, the material itself is usually not very relevant, compared to the quality and style of the door.

Size of Installation Area

The larger the area in which you wish to have a pet flap installed will generally correspond to a longer installation and, therefore, possibly a higher labour cost.

Location of Property

Labour prices will differ depending on where you live, however. For example, labourers are likely to charge less in the north of England, Scotland, and Northern Ireland but more in regions like the southeast of England.

Ease of Access

The more accessible the area of work is, the quicker the job is likely to be. In turn, the sooner a contractor fits a pet flap, the lower the labour cost will probably come to. The opposite is, of course, also true.

What Does Installing a Pet Flap Entail?

Now, let’s break down the steps involved in fitting a new pet flap. The exact method needed to install a pet flap will vary based on the type of pet flap and door.

A pet flap for glass door installation or a pet flap for wood door installation will be a different process.

1. Hiring a Contractor

You may wish to fit a pet flap DIY. However, if you’d prefer to hire a professional, you should acquire a minimum of three quotes from various tradespeople/companies, as well as references, before coming to a decision. This will give you better odds of hiring an above-average contractor and finding a better deal.

2. Cutting the Circle For a Pet Flap

The first step involves making the necessary measurements to know where the pet flap should be fitted exactly and where the hole will be cut out to fit the pet flap (plus its dimensions). At this stage, the labourer will outline the pet flap on the door.

Circle cat flap

Next, they will drill holes on the circle’s outline before employing a jigsaw blade to cut out the circle needed for the installation. It’s important to ensure that your pet is not behind the door when the hole is being cut!

Different tools and equipment will be needed depending on the door material. For instance, an electric jigsaw blade would be used to cut out a circle in a uPVC door.

3. Installing the Pet Flap

Next, in the case of a wooden door, sandpaper may be used to tidy up the door hole. It’s important that the pet flap is checked to ensure that the flap swings as it should.

Then, it’s time to drill the fixing hole before fitting the pet flap, per the manufacturer’s instructions. Finally, the pet flap should be checked one more time to make certain that it’s working correctly.

DIY Pet Flap Installation

You may fit a pet flap DIY if you wish. It’s a relatively simple job, and the manufacturer will provide instructions that should be easy to follow.

Of course, with any DIY job, there are risks involved. For one, it’s always important to take caution when using tools like drills or jigsaw blades.

In addition, if you want to fit a pet flap to a wall, a cable detector is necessary to pick up on gas, waste, or waste pipes, and electric cable before cutting through. Also, it’s essential not to cut through a structural timber or RSJ.

Square cat flap

If you doubt what is behind a wall, you should hire a professional to fit a pet flap to said wall.

A less serious but notable risk is that you could perform the job incorrectly. For that reason, only fit a pet flap DIY if you feel sure that you’ll be able to undertake the installation right. You’d possibly save somewhere in the range of £80 to £260 if you fit a pet flap DIY.

The Tools/Equipment to Fit a Pet Flap to a Wooden Door:

  • Measuring Tape
  • Drill and Drill Bits
  • Jigsaw Blade
  • Screws

In the case of a uPVC door, you’ll need an electric jigsaw blade. A drill must be used to cut through a wall. Other materials will be needed for fitting pet flaps to different types of surfaces.

In any case, the manufacturer will provide you with details and hopefully some, if not all, of the materials needed (e.g., an adhesive). You will not need a professional sign off once the pet flap is installed.

Types of Pet Flaps

In this section, we’ll discuss the features of each design of pet flap, their costs, and pros & cons, among other details.

Classic Pet Flap Cost

Also known as a conventional pet flap, this choice is as simple as it gets; it is a pet flap door that opens and closes manually. Classic pet flaps are cheap and simple.

On the other hand, they do not provide much security since pets from throughout the neighbouring, and possibly wild animals could enter your home with ease. Classic pet flaps cost about £10 to £25 per unit.


  • ✔ Simple
  • ✔ Not costly


  • ✖ Will not protect against bad weather
  • ✖ Lack of security

Lockable Pet Flap Cost

You may or may not need to pay a little more for some security in the form of a lockable pet flap. The average cost of such a pet flap is £10 to £30.

The manual lock feature on these pet flaps allows you to keep them shut through the night to prevent unwelcome pets or wildlife from sneaking in. It also makes your home less vulnerable to break-ins.


  • ✔ Not too expensive either
  • ✔ Added security


  • ✖ Danger of jamming
  • ✖ Risk of various mechanical faults
  • ✖ Not secure when unlocked

Magnetic Pet Flap Cost

These flaps work by responding to a collar or tag with a suitable magnet designed to trigger a locking system so that the pet flap may be used.

This collar or tag can be attached to your pet. However, if a neighbour’s dog or cat has the same version of collar/tag, they will also gain access.

It will keep out other neighbourhood pets and wildlife who do not have a suitable magnetic collar/tag. Magnetic pet flaps generally cost between £20 and £80.


  • ✔ Not as costly as microchip or infrared pet flaps
  • ✔ Relatively secure


  • ✖ Unlocking may not work right away
  • ✖ Neighbourhood animals may still be able to enter your home

Infrared Pet Flap Cost

You’d need to pay a little more for an infrared pet flap, but these pet flaps are significantly more scientific and highly secure.

An infrared key that comes with the product can be attached to your pet’s collar. This specific infrared key will unlock the pet flap but will not open for other pets, including those with different infrared keys if, by chance, they also have such a key on their collar.

You can also buy infrared keys for several pets if you live in a multi-pet household. Infrared pet flaps have an average cost of £50 to £100.


  • ✔ Very secure
  • ✔ You may buy several keys


  • ✖ Not a cheap option

Microchip Pet Flap Cost

This choice is similar to infrared pet flaps. However, it functions by detecting the specific microchip inside your dog/cat.

Since every pet microchip has unique coding, these pet flaps are, like infrared pet flaps, only accessible to specific animals.

Once more, you may provide access to several pets. Microchip pet flaps cost roughly £50 to £100.


  • ✔ Microchip cat flap/microchip dog flag is extremely reliable
  • ✔ Several pets may be granted access
  • ✔ More reliability than infrared pet flaps


  • ✖ Expensive

Pet Flap Repairs and Maintenance

One appropriate way to maintain a pet flap is to clean it as often as possible. This can be done with a cloth and warm, soapy water. You may need to fix or flatten a part of a pet flap if it becomes damaged or warped over time.

A handy DIY approach to repairing a small piece of damage is to simply attach a fresh piece of plastic using adhesive.

Of course, it’s essential to ensure that the glue is not toxic to animals. If a pet flap consists of metal strips, you could replace such strips if it appears necessary.

Dog flap

To winterise a pet flap, you should build a tunnel around it, either outside or inside, with the use of a second flap.

You can do so by removing parts of a wooden box and then attaching the box to the door. It is advisable to hang a piece of heavy carpet on the other side of the box.

This way, your cat or dog can still enter through the pet flap without the elements becoming a nuisance, whether through heavy wind, sideways rain, or simply the cold.

Removing a Pet Flap Cost

What if I later decide to remove a pet flap? Homeowners may choose to remove pet flaps if they’d like to upgrade to another type of pet flap, such as an infrared or magnetic pet flap.

A replacement pet door flap is likely to cost the same as fitting a new pet flap unless waste disposal costs are included.

Alternatively, homeowners may decide that a pet flap is not worth the hassle or their pet has no interest.

On average, it costs under £100 to have a pet flap removed and disposed of. You may remove a pet flap by yourself if you’d like.


It may result in higher premiums. It’s essential that you get in touch with your insurer and let them know about the pet flap installation, otherwise, your cover could be invalidated.
Pet flaps can last for decades, although it will depend on the quality and type of product. How well the pet flap is maintained will also shape how long it is likely to remain fit for use.
PetSafe is a popular brand of pet flaps. You can find their pet flaps online with a quick Google search.
This system allows you to set specifics as to how your pet may enter or exit (e.g., they can exit but not enter, or they can enter but not exit).
Classic pet flaps, in particular, are not very secure, and there is a risk with any pet flap that a burglar could break in.

However, some pet flaps are much more secure than others, with infrared, magnetic, and microchip pet flaps being the safest options.
For pet flaps that require batteries, they tend to half for about six months.
Most pet flaps can be fitted to a single or double glazed window, but the installation process is quite different to installing a pet flap, say, in the case of a wooden door.

How to Find & Hire a Pet Flap Installer

You may choose to hire a contractor if you feel unsure about the installation process or do not feel certain you would undertake the installation correctly.

On average, tradespeople charge between £40 and £50 an hour for this sort of work.

Here are some points worth considering when hiring:

  • Do they have qualifications?
  • What about their references?
  • What experience do they have?
  • What is their accreditation?
  • Do they have insurance?

A pet flap installer may have qualifications related to their trade. However, qualifications are not necessary.

Ultimately, their experience and references are the most important points you should take into account.

If, however, you’d like to check their qualifications and certifications, you can always ask the contractor or their employer.
