Absolutely brilliant
I cannot recommend Enlighten windows highly enough. Every part of my dealing with them was outstanding. Their technical knowledge and advice was excellent, it is quite rare to find people who have a really, really good understanding of their product, and they do. I write this having just had an after sale question, which they have sorted out perfectly.
We purchased Unik Funkis windows and they are beautifully made. From my research last year these windows were comparable or slightly cheaper than others of similar type I looked at , and they have a U - value very much better than that specified by current UK building regulations. Enlighten deal with many manufacturers.
Communication throughout the process was great, and they were spot on with their lead time management.
