There are no reviews for this business, be first to write a review! Did the online calculator on DIY kitchens web site and got to �4000 so hence my question. Sigma 3 Trade supply and manufacture a stylish range of high quality kitchens at trade prices. Text a link to your phone so you can quickly get directions, see photos, and read reviews on the go! But I have to say the quality of the sigma kitchens https://sigmaconstruction.uk/kitchen-installation.html I fitted was good and everything arrived on time. If you would like your kitchen featured post your picture and add #MySigma3Home – we would love to see how you enjoy your Sigma 3 home. We also tested kitchens from most of the biggest brands in our lab to find out how well-built they are, and how they stand up to everyday use from everyone in the family. We love fitted kitchens and our customers love their Sigma 3 Kitchens. We have over 40 years experience of making and selling kitchens from our 11 showrooms across. Both of these kitchens are half the price of Moben/Magnet. Only after further investigations did she realise how much mark up Sigma is making on these kitchens. It should be less than the DIY kitchens one really as well. Never bought from diy kitchens so i cant comment there but on price they have it nailed, if u have shares in kitchen italia bin them as they do exactly same as diy kitchens but at a big premium. Now ive read the blog and seen that sigma are entering in to the trade I might have to give them a call. Thank you Ali & Sigma Kitchens! So £1, 500 of hard earned money to Sigma for nothing. I have also stumbled accross DIY Kitchens and Wren Kitchens which are internet only (ie im in Scotland and cant get to their showrooms). Have to say diy kitchens do offer phenomenal value. I have been looking at Magnet and Moben (or Kitchens Direct as they are supply only) the ranges seem very similar and the price was almost the same. Pop by Sigma 3 Trade in Llantrisant for a chat about how we can help. All these kitchen providers get their products from exactly the same suppliers; Sigma just put a whacking mark up just for acting the middle man and having their so call ‘designer name’ applied. At Sigma 3 we have a wide variety of cabinet sizes so we can create your dream kitchen. Every Sigma 3 Trade cabinet is delivered fully assembled, saving you time and money during installation. Sigma 3 Kitchens is a family owned business and we’ve had a showroom in Newport for many years. We manufacture our own kitchens in our own environmentally friendly factory, using the finest CNC machinery and skilled staff.
