Superb experience buying my Velux roof windows from Roof Giant. Easy-to-use website, great value for money, and fast delivery. The windows are top tier and have completely transformed my space. Five stars! We are still to connect these to power.. 🤞🏠

As picture, it should be Anthracite grey, It turned up Goose Wing grey, I would have made them change it, but it was going to be a lot of hassle

Could not arrange a P*** up in a brewery
29th July 2026

On the 6th of July we placed an order for a 800 X 800 dome roof light from Roof Giant when my husband had the roof ready to fix the roof light it was completely the wrong size nothing measured 800 not the outside, the inside or the dome my husband took photos with a tape alongside showing this and I emailed RG to complain on the 14th July with photos (it was impossible to get through on the phone) We waited over a working week and still no reply and the customer was not happy so we gave up on RG and he phoned around and found some one who had what we needed in stock My husband is a sole trader and can not afford to loose this money but we had to try to keep the customer happy and not getting any help from RG On the 22nd July out of the blue a delivery turned up with another roof light NO call no email or anything So I phoned RG left a message asking for an urgent call back. Suzanne phoned me back I gave our order number, and she said she could see the email but couldn't find the reply “I said that’s because there wasn’t one” I explained wat had happened and she said she would look into it and call me back One week later 29th July I again phoned RG and this time got Adam who said they had tried to stop the delivery of the 2nd roof light after my call on the 22nd but it was too late Yes because that’s why I phoned on the 22nd to tell you it had arrived. I explained again and he then said “could my husband not remove the sky light that he had purchased from the customers house and put the 2nd sky light in its place” I said are you mad why would the customer be happy with that???? And why would my husband want to?? He said he would arrange for a pickup he said he would let me know when but I am not holding my breath As I said my71yr old husband is a sole trader and we don’t have storage or the money to loose

Don't let them organise a drink in a brewery
29th July 2026

6th July we placed an order for a 800mmX 800 dome roof light When my husband tried to fix it to the customers roof nothing measured 800mm we took photos along side a tape and I emailed Roofgiant on the 14th July Then nothing no phone call or email so to keep the customer happy he phoned local company and got a new skylight still nothing from R/G then on the 22nd July out of the blue we had a delivery of another skylight !! I phoned R/G left a message and Suzanne phoned me back she said she cant understand why we did not get back to us or what has gone wrong but she will get back to me Now 1 week later and still nothing I phoned again this time I spoke to Adam He said that after my call they had tried to stop the delivery but it was too late (what ??) the he said could we remove the skylight (the one we had to go a buy)from the customers house and replace it with the one they sent on the 22nd !!!!!!??? I said do you think the customer would be happy with that and that without the money we paid for the new skylight I was gobsmacked he said this But then he said he will arrange for the collection of the 2nd skylight I asked if he will contact me with a date for this and he said of course My husband is a sole trader we cant afford to loose money or have storage to keep things this big hanging about.We have used RG before and have been very happy But when things go wrong everything changes I dont expect that we will get a call or any money back
