First time I have used this company. Gave measurements as directed on the website. Loft hatch fitted perfectly. Great improvement from previous wooden hatch which had no insulation. This has transformed the warmth upstairs. Excellent product which is made well.

Good quality and excellent delivery service as always Customer had strange size so ordered special
-
Although 4 or 5 times the price of a plastic standard loft hatch from Builders Merchants, this is well worth the money and as long as you follow the detailed measurement instructions it fits like a glove. My was perfect for my unconventional loft hatch size where I had previously needed to pack out the sides for a plastic hatch. This is also quite heavy compared to the plastic ones but this also shows the quality and craftmanship of the made to measure product.
