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.

Outstanding product and outstanding service.

We ordered a bespoke loft hatch as our previous one was so small we couldn't even get large cardboard boxes in. This one is absolutely perfect and fits like a glove. Excellent materials used, exceptionally well made and the quality of customer service is second to none. Extremely helpful and friendly advice when I phoned them before ordering. Thank you so much I would highly recommend your company.
