Very Excellent service with polite, honest and friendly staff. The rooftop Windows are amazing and modern. We went with the Black framed option with electric operation. They kindly shown how to use the controls and provided additional advice after fitting the windows professionally and in a timely manner. Highly recommend GRP roofing service company to those who are looking for a hassle-free excellent service and new windows.

We had GRP London install 2x Velux windows. The quality of service provided and communication throughout was fantastic, the windows look great.They offered a complete service which included a site inspection, provision of all material and windows, installation and disposed of the old units. I cannot thank them enough and will use again, I highly recommend.

Had a new remote controlled Velux roof window fitted, they did a real nice job for a good price with no hassle I would recommend this company.
