Good price and selectable delivery
Good price and selectable delivery charges, from free 21days or quicker at a cost, fair enough. Others offered far cheaper windows then hit you with £75+ delivery charge when you went to pay!

Broken twice in delivery
Met 2 week delivery date. Arrived cracked. Further 2 weeks. Broken again. Finally got unit. Online tracking doesn't work at all. If you leave a message they don't call back but when they do answer they are polite. Quality fine. Price is good. Not a great experience but provided I wasn't in a rush I'd use again

Awful company, Beware!
I initially ordered 2 pieces of glass for my front door 16/2/26, 2 months later, currently 17/4/26 I still have not received the glass I ordered. The phrase you will hear most when dealing with this company is: 'I've just checked with manufacturing, the bits we needed are now in from our supplier, and its being loaded on the delivery van this evening' - I have been told this over and over and over again and its a lie every time. What you're being told is any excuse to get you off the phone. Of course the delivery never comes and the cycle repeats. The units were initially the wrong size as somebody couldn't read a tape measure, such a basic mistake is laughable, but the way that its been handled is the worst customer service I have ever had with any company ever. Avoid this company like the plague, save your money and sanity its just not worth buying from them, buy from anyone else! I've requested my money back or the glass I ordered multiple times and I still have nothing......
