I recently had a lantern light, window and bi-fold doors installed by Unique Windows. From my initial approach and receipt of a verbal costing to a firm quotation, the price remained the same. I was advised of a delivery 2-3 weeks , this was achieved and within two days of delivery all units were installed. From my first approach I found the staff at Unique Windows to be extremely helpful , their fixer was on time , polite and extremely good, providing me with a perfect product and installation. At no time did Unique push their product on me or continually chase for an order, this particularly impressed me.

Unique installed my new french doors to a balcony. I was incredibly impressed with the quality of work and professionalism of their staff. On top of that they went out of their way to get the job done within a week of me asking for a quote.

It has been a real, real relief to deal with window fitters who are not sales people. This company knows their market and their responses to any queries or requests were genuine. I would highly recommend them and have no hesitation in using them again. They fitted two bays including all the shelves and a smaller window in two days. They were tidy and professional. They were a joy to have in the house - genuinely friendly! Thanks to Stuart, Darrne and Charlie and Nick.

We had all new windows fitted in the house. They look very smart and elegant. So much that I had only praises from my neighbours and friends. Unique Windows did a fantastic job at a very competitive price. Very tidy, quick and efficient. Overall, an excellent customer service. I have already recommended Unique Windows to my neighbours and friends, and I believe they have contacted this company already. I will certainly use them again

I would thoroughly recommend Unique Windows (London) Ltd who acted in a very professional manner throughout the whole process from initial contact to installation. Our Bi-Fold doors add a whole new dimension to our extension and we are delighted with them. We also cannot thank the installer enough as he worked in the pouring rain to complete the job at the time & date agreed.

I would recommend Unique to anyone looking to replace their residential double glazing. We had all new windows fitted in our London flat. Our requirements were slightly out of the ordinary (we wanted higher quality aluminium sash frames and we wanted them fitted to a particular size to maximise the light). We contacted two London based independent firms and one national firm for quotes. Unique was the best price from the independents and the most knowledgeable and willing to accommodate our requirements. The national firm came to our flat and left without giving a quote when they realised we didn't want their standard uPVC frames (despite us asking for, and them advertising, aluminium on their website). Unique were very accommodating in all of their appointments made with us. They sourced the windows quickly, and fitted them in a day, despite a difficult installation due to quirks of the building. The fitters were highly knowledgeable and courteous. The windows themselves are extremely high quality. There were one or two minor adjustments that were required post-fitting and Unique came out quickly on two further occasions to sort this. Their contracts, paperwork and payment process were professional. They also provide a full guarantee scheme that is third party-insured. Having conversations with others left me concerned that we would not get quite what we were after, but the finished product is exactly what we had hoped for. I would not hesitate to use again.
