  • I was looking for a loft solution for our 1930s build and found the SDS Made To Measure hatch. The customer services team were really helpful in finding the right product and how best to work with the lath and plaster so that the hatch fitted flush against the ceiling. The hatch turned up earlier than expected and fitted without any problems. We now have a great insulating hatch that has made a real difference to the warmth of our landing. Great product and service.

  • Easily the best loft hatches I fit. This is probably the 5th made to measure hatch I have ordered. Dead easy to fit. Great closing mechanism and they look great when installed. Highly recommended.

  • Came two days before delivery was expected, was well packaged. It took longer to get the old fittings out and off the rafters than it did to fit this hatch. I used 3 plaster board lifters I have (B&Q £15) to steady the hatch in place and it just slipped straight into the opening with ease. Good measurements are essential. Well worth that bit extra £ for this finish than messing and angling with wood hatching, lot lighter too. The pole was forgotten on my order but one email to the company and it was sent immediately and arrived next day with no hassle. Hatch has 3 fixing holes per side and I added a few more for the hell of it. The 25mm frame helps the ceiling finish, so if you have ceiling blemishes around the hatch as I did with plasterboard showing then the 50mm frame might save you a heap of time. Not often I review a product like this but I have absolutely no complaints and far more importantly nor does my wife, excellent product and firm. Buy with confidence.

  • The sevice was exemplary: the hatchway came on time, was well made and correctly sized. the finish was very good. My one concern is the lock and opening arrange,ment: the lock is takes time to getting used to, and it is not always clear that it is locked in the closed position: there is a risk that it could fall open unexpectedly. The rod 'key' used to open the lock and lower the hatch is flimsy and will wear quickly, and possibly break.

  • I have bought numerous loft hatches from this company and have found them to be of exceptional quality. They are very well made and come with their own operating pole. I always recommend paying a little extra and having the silver cover over the insulation on the back of the loft hatch. Be mindful of you are buying one to replace an existing loft hatch as the standard ones come with a 25mm trim, I usually upgrade to the 50mm trim. An option for a 75mm trim would be welcome for me if I was adding a slight negative. Brilliant product, highly recommend. Ben

  • I ordered 2 of these hatches for an extension I have just had built. I was planning to make my own, but I I so glad I decided to buy these instead. They are really well constructed to the exact dimensions. Very easy to install, I did mine on my own in a few minutes. And they look really nice. Strongly recommended and worth the money.
