What are Perfect Fit Blinds?

The Perfect Fit System is an easy click in frame solution for venetian, roller, and pleated blinds. It’s fitted without drilling, screws, or holes, providing complete child safety.

Any 25mm venetian, roller, or pleated blind can be fitted into the system, allowing the full range of colours and patterns that your chosen supplier provides. This also means you can have 100% matching fabrics, patterns, and colours throughout your home.

All blinds in the PF System provide complete child safety with a spring system for easy controls. Simply raise or lower the blind to your chosen position, with the use of a tab, let go and it will remain in that position. If you decide on a venetian style, you’ll also receive a wand to tilt the slats for privacy and light control.

The finished blind is fitted to the glass frame, allowing you to open your windows or doors without ever needing to touch or move the blind.

How it works

The Perfect Fit frame will click in between the glazing and the beading of uPVC windows for a seamless fit on the window or door.

You can see an example of a clip in the photograph on the right. This clip is then attached to the frame which holds the blinds.

The blinds are installed into the frame with screws to hold it, rather than into your windows or doors. So your warranty remains intact, and you don’t permanently damage the frames.

This system can then be clipped onto your windows, doors, or conservatories without the need to drill or any screws going into your window frame.

The second photograph on the right shows an example of a fitted blind with the PF system. An added benefit you may notice, is that it is fully attached to the window, so when you open or close the window – it will stay in position.

The PF system works great in any room, doors, or even conservatories. The frame comes in white, golden oak, and mahogany – to match your uPVC colour. The blinds however, are available in a whole range of patterns and colours depending on your chosen type and supplier.

Any Pleated, Roller, or Aluminium Venetian colour / pattern can be used in the frame. With most suppliers, this will give you over 200 options to choose from.

… and it won’t ruin your guarantee

Drilling into your uPVC windows, doors, or conservatories will void any guarantees provided by the suppliers and installers. Not only that, it leaves permanent damage. There will always be a hole where the screws were – but not with Perfect Fit. There is no drilling or screws into your uPVC – keeping your guarantee and not causing any damage.

Regular blinds require screws to be drilled into your conservatory to hold them in place. This leaves permanent damage to your conservatory and voids any guarantee provided by the suppliers and installers.

With Perfect Fits, they just clip in. That means they can be taken out at any time, with no damage at all. And they’re securely clipped in, so there’s zero chance of them falling out.

This makes them even better for conservatories and doors, but also…

The fit against the window makes them especially useful for windows or doors you open regularly.

In the past, not only would the blinds void your guarantee by drilling holes into the uPVC, they would also restrict access to the handles. You would have to raise the blind to access the handle, or worse, reach through the blind potentially damaging it. Not only that, but it also took up valuable space on your window sills.

With the PF system, the blinds are fitted behind the handles, allowing full use for opening and closing windows or doors, while still having full light and privacy control.

Looking for blinds for your french doors?

This is the best solution on the market today . You can save your guarantee, and easily access the doors with the blind fitted.

They’re also great for inward opening doors, byfold doors, and patio doors.

For any of these types, you’ll be able to have full, unrestricted access to the door. That means you’ll be able to open the door without having to touch the blinds, and when you do open it, they won’t swing out or get trapped in the door. They’re securely fitted against the window, in the frame, so they’re ideal for regularly used windows or doors.

Our Review – Buy or Pass?

PerfectFit’s are a great solution for conservatories, doors, and windows that you plan on opening.

There’s a number of benefits to using them:

  • No holes, screws, or damage to your property
  • Extremely simple to take down if ever needed
  • Fastened to the glass frame, so you can open the window/door without it swinging out or getting in the way
  • Matching blinds available for ones outside of the PerfectFit system
  • Hundreds of colours and patterns available
  • All components manufactured in the UK

But there are a couple potential downsides to note:

Firstly, they can be more expensive than without the frame. If you don’t need access to your window sill, and it’s not for a door or window which you’re regularly accessing – then this may be acceptable. But for anything where you would normally drill into the uPVC, this will be less expensive than permanently damaging it and voiding your guarantee.

The final point to consider is that unfortunately the system does not fit every type of window. You’re most likely to be fine, in fact, it will fit 95% of UPVC double glazed windows with a bead depth between 18mm and 38mm. But there are obviously some windows where it does not fit.

If you’re unsure if that’s yours, don’t worry. You can arrange an appointment with our recommended supplier, Hillarys, and your local advisor can answer that for you.


We highly recommend Perfect Fit Blinds, especially to anyone with tilt and turn windows, conservatories, doors, or windows regularly opened.

There’s nothing else that works serves this purpose better. And for homes with children, they’re extremely safe to have around – as there’s no cords, free-hanging or otherwise.

Frequently Asked Questions

Do you recommend self installing?
While the PF frame is designed to be simple to install, allowing you to easily take them down and put them back up yourself – if needed. This doesn’t guarantee they’ll be measured correctly.

Absolutely, just pull the tab up and down to raise or lower the blinds, and tilt the wand to change the angle for full light control.
