There is a company who i used that cover the whole uk they are easy glazing very good company very fast service had a new double glazed unit made for me with a hole in it for the cat flap visit there website and have a look all contact details are on the site Easy Glazing | Cat Flaps | 24 Hour Emergency Glazing and they stopped me having to let my cats in and out all the time what a god send JohnSmith

Yes you can. My brother is a window fitter and often has jobs where he fits special cat flaps into existing upvc, and double-glazed doors. Speak to a specialst double-glazing company and get a quote. Shop around though as prices can vary wildly. At least if you go to a specialist they'll have all the correct tools and will do the job properly without compromising the effectiveness of your double-glazing.

I am just looking for your same deal.......did you discover any cheaper prices?I ll let you know if I do...
PS I am very new in this field :-)
but trying my best

NO sorry

we had this done a couple of years ago.
was just over 200 quid fitted.

however, if you are willing to do the work yourself (ie all the measuring and fitting etc) there are glass companies out there who are happy to cut the glass to your size. was quoted £95 for this option but opted for more expensive in the end as i wasnt sure of measurements.

hope this helps someone.

ps. if you ever need to change your flap try and find one that is same size as previous hole to save on expence.

yes - you can have a cat flap installed in a glass unit, but the unit does need to be replaced!

I understand this thread is old but i thought i would shed some light.

I used a company called Ask Glass who cover the whole of the uk. They fit cat AND dog flaps into glass and wood and plasic doors. Badicly everything.

I used them to fit a cat flap into my patio door and it cost 170£ including the cat flap! I even got a free cat toy.

Would defiantly recommend them!
