We are so thrilled with our new…
We are so thrilled with our new kitchen. From the moment we received our brochure to installation it was all so easy. We knew what we wanted and our designer brought our kitchen to life. The installation boys were great and pointed out a small defect on a door and had already ordered a replacement ( we hadn’t noticed it) . All queries were dealt with promptly and professionally. All in all we would certainly recommend sigma for all of the above and their quality .

Excellent customer service Cardiff
I had a fitted kitchen approx. 7 years ago from Sigma Cardiff. I had a few issues with it and even though it was out of warranty the quality of service was just as impressive as when I bought the kitchen. Within 24 hours I had a visit and we were able to resolve the issue quickly and to our complete satisfaction. They even remembered us when we initially went back. Excellent service by the sales team and the fitters who decided to replace all our kitchen doors. Thank you to Jamie, Dennis and Matthew.

Incredible service
Sigma at Swansea have installed our magnificent kitchen and I can only praise them, for the incredible job they have done.
From the moment I visited their showroom, I felt valued and welcomed, with a friendly smile from all members of staff. Gavin our designer was incredible…
From the moment I explained what I wanted, he listened carefully and offered his experienced opinion in a gentle and respectful manner. Gavin designed on paper, exactly what I had created in my mind for the kitchen. Gavin demonstrated the ability to generate a practical but beautiful kitchen seamlessly. The schedule of works they produced was kept perfectly and they remained - right on track!
I was introduced to Beth and Rob at the store, both of whom continued the professional standard of care, I’d been used to by Gavin. Even the delivery drivers were great, punctual , pleasant and so helpful.
As for Dean our fitter, words begin to fail as he was such a craftsman! He worked tirelessly and meticulously on our kitchen and produced a phenomenal result! He identified imperfections that I couldn’t see, insisting that it was replaced within a day or so. He is a perfectionist and that is reflected in the beautiful work he produced.
I wouldn’t hesitate to recommend Sigma at Swansea. They have a high standard of care, quality control and flair for producing beautiful homes. Thank you all.

Zero regrets
Zero regrets enlisting Sigma's support as part of our renovation. The team were a pleasure to do business with from first consultation, through multiple designs, through to supply and installation. Each conversation full of expertise, professionalism, understanding and a desire to help. The kitchen looks amazing. Thanks Jose, Craig and team.

Really happy with my new kitchen/diner
Really happy with my new kitchen/diner. The designer, Negar, listened, was patient, worked with my budget and cleverly designed a lovely kitchen in accordance with my likes and needs. The installers were experienced, helpful and skilled, finishing to a high standard and quality. Once the plans were in place the work went ahead requiring minimal input from me. Overall a lovely, high quality, hassle free new kitchen diner that suits me.

Excellent communication from Barbora and inspirational design. Her advice was clear and timely. Any potential hitches were identified and resolved. Barbora established what my dreams were for a new kitchen, she got everything in and within budget. She was supported by an excellent team, all were knowledgable and enthusiastic. I am delighted with my kitchen. I particularly recommend Barbora for her depth of knowledge on marketwide products available and design skills. Dawn Harris

We are extremely pleased with our sigma…
We are extremely pleased with our sigma 3 kitchen. During the design process Negar welcomed us to the showroom and listened to what we wanted for our space. Her design was beautiful and the end result looks exactly like the images produced in the showroom. Our kitchen has gone from a dark room to a bright room which feels so much more spacious. We have so much more cupboard and storage space and a beautiful peninsula to sit and enjoy the room. The quartz worktop and splashback is of a very high standard, it looks absolutely stunning in the room and complements the beautiful cupboards. Throughout the process, Louise, the installation manager was easy to contact with any queries and most helpful. The only negative is that the timeframe in installing the kitchen wasn’t adhered to and it did take longer than anticipated but we got there in the end!

Long time relationship resulting in excellent kitchen!
I worked with Sigma 3 for over 3 years as the economy gave our build project a bumpy ride. They were brilliant! From the designer who spent many hours with me to the nitty gritty paperwork guy and finally to the lovely installer. All made the project feel easy when it's quite complex. I felt in very safe hands and could not be more pleased with the end result.

A new kitchen is an expensive purchase
A new kitchen is an expensive purchase, it's the heart of the house so you want your money and your wishes to be spent wisely. The customer service from start to finish was superb.

Superb service from design to installation…
We popped into the Swansea showroom on a whim, having looked at many other suppliers. We had an exceptionally warm welcome from Morgan on both our initial visit and subsequent ones. He was great to work with during the design phase. Was prepared to listen but also to encourage us to be bold. His design was exceptional. He supported us with site visits as our building work took place, as did Tony, our installation manager who continued the excellent service.Throughout communication was excellent, including delivery. John Paul, our fitter continued with the positive engagement. Minor issues were promptly resolved and the result us a truly bold and unique kitchen that has a real wow factor. We have worked with Beth, the Swansea branch manager many years ago and she continues to deliver a really exceptional customer service both herself and though her team. Thank you all - it's fabulous!!

Sigma 3 - a great non pushy company
Sigma 3 were a great company to deal with. I first went into the showroom with ideas, but no appointment. That was fine. I and my friend found the staff really accommodating, and started chatting to Morgan, who was easy to talk to. Over the next 3/4 visits I nailed down my likes and Morgan made each visit fun. He even helped get my wheelchair from my car! Great installation too by Dean.
I love the difference and ease of use in my new kitchen. I was never rushed, and each minute detail was carefully discussed.

Exceptional quality throughout
Five star quality from the moment we stepped through the doors at Sigma 3 (we actually arrived early for our appointment, but was invited in for a pot of tea - a great first impression).
We had our initial design discussion with Tabitha, who was great throughout, talking through the options, and showing us how it would look in the showroom, so you could touch and feel the quality.
Fab designs, working the space. With adjustments made with no fuss post doing the check measure.
Clear communication on delivery slots, and packaging was clearly labelled and robust.
There were a couple of missing items, but a quick call to Craig, the installation manager, and they were with us in no time.
Delighted with the final finish. Fab quality, and really accurate measurements. Overall, great value for what we've got.

Aftersales for consumer poor
Had a sigma kitchen fitted a number of years ago, looking for a replacement plinth. There was no response from the 'contact us' page, and then I contacted 4 times over 10 days, finally spoke to customer services who couldn't really help me. This is a trade to trade business so if you want after sales that you can liaise with go elsewhere. Disappointing
