SMA have been absolutely excellent to deal with as have their partner Aqua Bathrooms. From start to finish SMA were professional. They understood our requirements well, were clear on the scope of the build and the fixed price quote was delivered to. They kept to their estimated timeframes as much as possible and provided us with a high quality finish. Where there were minor defects SMA quickly rectified them without any hassle. A superb firm that I would have no trouble in recommending

SMA have done a fantastic job of our loft conversion. Having been recommended them by multiple families at our kids school, they certainly delivered a quality product & would not hesitate recommending them. The workmanship is exceptional & as they say ‘you get what you pay for’ and all came within budget & on timescales. A very happy customer. Jack

So happy with our loft, such great quality workmanship. Sales team was amazing to work with & the whole team helped to create the perfect extra space we so needed within our home. The quote was higher than some others that we got in to price but the end result was definitely worth it. They also offer a 10 year warranty! Will be coming back when we look to undertake our extension!

SMA completed our loft in September 2022. The standard of work was exceptional and all of the staff/trades were warm, friendly and brilliant at their craft. We had to wait quite some time for the build to begin from placing our deposit, but the wait was worth it and the right thing to do given the size of our investment. We wanted to make sure we were working with the best, and SMA truly were. Couldn’t recommend them highly enough! Kate and Stu
