KP Glass always give a good service. They are a professional and friendly company from start to finish. I've just had a back door and window fitted in my sunlounge. The two fitters were friendly and polite and left everywhere clean and tidy. I was very impressed that not only did they sweep up inside but outside too. I wouldn't use any other company and recommend KP Glass to everyone.

Amazing work from the KP team. They supplied and installed some decorative glass for our original Victorian front door. They were able to match exactly the design we wanted and have completed the work in record time ! Thank you to the whole team at KP !

Without hesitation we would highly recommend KP Glass who have recently installed new windows and replaced a glass panel in our garden room. Providing a professional, friendly and most helpful, courteous service throughout the process from the initial consultation to the final fitting. Gemma the Administrator kept us promptly and fully informed of the delivery and fitting timescales and the three window fitters were always prompt, professional and also polite and courteous. We are delighted with our windows that look great, are already proving to be energy efficient at a cost that we feel is competitive
