Great service for a great price. Throughly recommend.”

“We had ours installed just before the heatwave started. The film has made a huge difference to our conservatory. The heat was unbearable in there before, Now we can use the conservatory even with the weather as hot as it has been recently.”

Thank you for a fab professional job, and for your kindness. Invoice has been paid, and it will be my absolute pleasure to recommend you highly to my neighbours! I may well be in touch soon with regard to our Sidcup property.

Ben Baker

Perfect job , would highly recommend this company .
On time , on budget and cleaned up after work completed. Exactly the finish we were hoping for.


Communication with Stuart was really good the whole way through the process. The tints installed in my flat have drastically reduced the heat coming in which was the main reason we were looking for this service. Process was very quick and can not even tell there are tints on the windows. Thanks a lot.

Dear Stuart (and Family!!)

What a great job - I can't thank you enough, and will gladly write a testimonial for your professionalism and speed, and in due course, one to speak to the temperature in the room!

I have the invoice, and will do a transfer immediately, but can't find the bank details. Do let me know.

With thanks and best wishes to you for your warmth, enthusiasm and professionalism. A high-class outfit, which I wont hesitate to recommend.

Erica B

Very professional, prompt and polite. Extremely pleased with our window film. We over look a lovely park but also a public foot path so just wanted a bit more privacy without losing our view.  Highly recommend KWF!

H Elliot

Excellent communication, extremely helpful when advising us on what would be best for our conservatory, fast and professional service! Thank you!

Hannah H

Excellent advice and service. Would highly recommend for anyone looking to either find a privacy, heat or glare reduction window film. After living with suggested samples (with full product information supplied), the installation was speedy and professional. Cheaper alternative to having windows with treated glass.

J Smith

Had a mirror effect film put onto sliding wardrobe doors, absolutely brilliant job and I couldn't be happier with the results.

The guys were absolutely brilliant too and knew what they were talking about.

10/10 would recommend
