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.

I don't often add a review, but given the service we had from GRP London, felt it was definitely needed! Had a new window installed in our very old loft bedroom. Neil took the time to listen to what I was looking for (as space and size is a bit unique) and I have to say, after speaking to countless builders/window specialists, Neil was the only one who took the time to listen to what I was after. The communication throughout was fantastic and the end result looks great. Really helpful at every point, site inspection no problem and disposed of the old unit - and tidied up after. Space was left lovely and clean (and this through the hottest weeks we have had on record!). I cannot thank them enough and will use again, I highly recommend.

I used GRP to replace the skylight in my bathroom. They provided great service and a quality installation. I got quite a few quotes from different providers for the work, but GRP were the only ones who actually came out for a site visit. While their quote wasn’t the cheapest, I was confident they’d bring it in on budget and be able to complete the work as quoted, because they’d been out to view. They were also the only provider to recommend using a PU coated window, which made sense given the skylight is in the bathroom so has to cope with a lot of steam. They took away the old window and left the site clean and tidy. I’d recommend using GRP to anyone who need a skylight installed or replaced.

GRP London replaced the velux windows in my flat and their service was excellent. Neil was very responsive, fair and patient. He came out of his way to visit my property in order to give me a quote quickly. I am so pleased with the end result - I wish I had gone it done earlier! Would totally recommend using this company for any roof window fitting and installation.

Would recommend using GRP for anyone that needs a skylight replacing or installing. Skylight that required replacing was above the stairs in a particularly difficult area to get to, Neil and his team installed scaffolding to get to the space and quality of works was excellent; they were extremely tidy. Neil also noticed whilst on the roof some flashing & tiles were broken and repaired this as well. Would definitely use GRP again for any windows needing replacing.
