I am very pleased with the windows and fitting of them.

I am very pleased from start to finish with my Unique windows. They installed two double glazed laminated bedroom windows at the front and back of my house. From walking into their showroom in Carshalton and being greeted by Neil, one of the owners and his partner Rebecca, they were both, very pleasant and most helpful. He gave me an estimate that same evening. I had obtained 3 estimates and he was very reasonable. From ordering the windows, they were fitted within 6 weeks. Darren the fitter who installed the windows made a lovely job, and they look great. I would certainly use them again in the future.

The whole process of it all was brilliant from the start of the consultation to the windows being fitted. Chris was such a nice guy who explained everything clearly of the whole process even though I kept being indecisive he was still patient with me. The communication was good. Rebecca who works at the office was updating me what is happening now and again which good too. The fitters came it was such a quick process as well. They clearly knew what they were doing. They were both nice guys too . The end result were we are delighted with the fabulous windows and overall will I recommend this company to my friends I sure will do.

We had Dave and team in to fit new windows as part of a wider refurb. They were an absolute pleasure to deal with from the outset to completion. They were very quick, clean and courteous, working around the rest of the team working on the refurb. The windows themselves were of the highest quality, competitively priced, and have completely transformed the house. I can't recommend Dave and team highly enough.

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.

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.

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.
