Fast delivery, perfect fit, good price, quality build. What more could you want?

Fast efficient and reliable service with a great product that was easy to fit. I had 2 bespoke size loft hatches made and they were both perfect. Highly recommend

All OK good service.

Faster delivery than expected. Fitted perfectly and easy to fit. Only one hiccup and that was that it was supposed to come with a long locking pole but they only sent a short key. After a phone call the missing pole arrived after a couple of says.

Easy to fit as accurate in manufacturing.

I'm pleased with this. It's my second loft hatch from Jupiter Blue, but my first custom sized. In place it has a very low profile and is suitably discrete (I needed to install it in a bedroom ceiling, so appearance was important). It arrived faster than expected, well-constructed to my specified sizing. It was easy to fit (I'd gone for quite a large hatch, so I needed a second pair of hands for a couple of minutes to help me just get it up into position in the opening ahead of screwing). Packers between the frame and joists/noggins prior to tightening, as suggested in the instructions, is definitely recommended, as the fit is good and any warping of the frame by tightened screws is only going to impair operation. The lock is a standard triangular fitting such as you'd find on an external electrical or gas meter box, so it's easy to source a cheap backup for that inevitable, embarrassing moment when you've put the supplied opening pole down somewhere and can't find it. Overall, I would have no hesitation in buying again.

I ordered a bespoke hatch due to the size of the customer's loft opening. The delivery was in line with the advertised manufacturing lead time. The hatch was extremely well made, easy to fit and looked great in situ. I would definitely order again

Fantastic product. Love our new insulated hatch. Looks very professional and really is precision made to measure. Was a little awkward to install given its weight but we (an OAP and a short person)managed. Customer service was great as the pole was missing but arrived within 48 hours.
