What measurements do we need in order to make your hatch?

Please supply us with the length and width of your loft opening (the distance between the joists) in mm and then deduct 5mm from each measurement (please note you'll be asked to do this when placing your order). This is to allow for the loft opening being marginally out of square and gives a small tolerance when fitting the hatch (please call for advice if unsure or the opening is badly made). The external frame will extend 25mm on each side beyond these dimensions, we can extend this to 50mm if required (you'll be offered this option when placing your order).

Made to measure Loft Hatch description

A high quality, precision made hinged metal loft hatch suitable for all types of house. Each hatch is made to your exact measurements. the hatch is designed to be subtle and clean with a minimal protrusion of 7mm from the ceiling when fitted. All hinges and fixings are also concealed. The lid is fitted with a neat alloy lock.
Construction and finish Each hatch is fabricated from corrosion resistant 1mm Zintec Steel (Zinc coated). The frame and lid are powder coated white RAL No. 9010 with 20% gloss for a satin finish. The hatch frame depth is 63mm (going up into the loft).
Insulation and draught resistance

A primary function of any loft hatch should be to keep heat in your home and cold air draughts in your loft. Loft Hatches are an increasingly important part of building regulations relating to the conservation of heat and power within our homes.

Our hatch design features a concealed seal between the loft door and the frame. This results in an incredible airtightness rating. The lid is filled with 50mm of exposed mineral wool insulation. This hatch has a U value of 0.32 and complies with the requirements of Part L Building Regulations.

Lock options

Standard - Tri-drive lock with an O-ring seal on the shaft for the ultimate airtightness.

Key lockable - key operated.

Both lock options operate a chamfered cam which progressively applies pressure when closed to ensure the best possible airtightness.



The hatch is actually 63mm deep (from the ceiling line, up into the opening).

Delivery times

Quoted in working days (sat/ sun not classed as working days).

Installing your loft hatch

Every hatch is supplied with easy to follow installation instructions and screws for fixing the frame in place. To install, screw fix the hatch to the timber surrounding the loft opening.


The insulation used within this hatch is CFC and HCFC free. The ODP is zero and is compliant to the code for sustainable homes standards with a global warming potential (GWP) of zero.

Quality product, accurately made to my specified dimensions

We recently had our loft access moved from one of our bedrooms onto the landing ceiling which is much more practical. While doing so, we thought it would be good to go for a bigger hatch to provide more practical access, but didn't want to risk having something that would stand out like a sore thumb on the ceiling. This product meets our needs perfectly, and when fitted is extremely tidy, and you hardly notice it's there despite its large size. The only things to be aware of, being that it's made of steel, are the weight and chunkiness of the hatch door (which could cause injury if accidentally allowed to drop open), and the sprayed finish of the door and frame, which is beautifully slick but may be hard to touch up nicely if it gets scratched (one would probably need to spray paint it to maintain the finish, rather than use brush paint). But these are relatively minor considerations, and as long as the usual care is taken, they do not detract from the design or quality of the product. A minor observation regarding the loft hatch pole is that the end of the pole is made of rough metal, and could easily scratch the door panel if this was allowed to slip off the catch and onto the panel surface. The pole is very cheaply made by comparison to the hatch itself, and could be improved if the end that locates into the latch was made of a hard polyethylene plastic rather than metal, thus eliminating any risk of scratching the paintwork on the hatch. I've covered the end of mine in gaffer tape to avoid any such risk, but again if you're careful this shouldn't be an issue. It's essential to note that, when ordering a bespoke size, it is vital that you follow the measuring instructions precisely to allow a necessary small tolerance to enable you to locate the frame square into the hole, packing the edges where necessary once the fit is nice and square. Without this necessary tolerance, the frame could end up being a tight fit between the joists, leaving you with no allowance for adjusting the installation; and if your joists are not all perfectly square (which they likely won't be), this would lead to the door catching when you close it. It's therefore essential to follow JupiterBlue's instructions when specifying your sizes. It's also worth noting that mine was manufactured perfectly in accordance with the dimensions I specified on my order. This allowed me to install it with just the right amount of room for movement to ensure an absolutely perfect fit all round. I'm very pleased indeed with this product overall, and would definitely recommend it.
