If you’ve got a fitter, or you’re doing the work yourself, you don’t need to pay an installer’s margin on the doors. We supply made-to-measure aluminium bi-folds ready to install, with the gear pre-hung and set, the glass in, and the frame packaged to survive the journey.
Trade, self-build and confident DIY all welcome. We’re not precious about who’s fitting it — we just need the sizes right.
Every supply-only door leaves us:
No missing parts, no “the handles come separately”, no returning to us for trims three days into the job.
Supply only makes sense if:
Supply and fit makes more sense if:
We do both, at the same quality. See supply and fit bi-fold doors for the installed option.
One important thing about certification. If you buy supply only, the Building Regulations compliance for the installation is the fitter’s responsibility, not ours. A registered installer can self-certify it; anyone else needs to notify Building Control directly. It’s worth sorting before the doors arrive rather than at sale.
This is the part that goes wrong, so read it properly.
Measure the structural opening, not the existing frame. Width and height, at three points each — top, middle and bottom for the width; left, centre and right for the height. Use the smallest of each set.
Tell us the deductions you want. Doors are normally made 10mm under the structural opening on width and height to give a fitting tolerance for packers and levelling. If your opening is out of square, you may want more.
Check the head is level and the cill is level, and tell us if they aren’t. A bi-fold hung in an out-of-level opening will not fold correctly no matter how good the gear is.
Confirm the threshold type — low or rebated — and the finished floor level inside and out.
Confirm the configuration — number of leaves, stacking direction, whether you want a traffic door and which end it goes.
Send us your measurements and a photo of the opening and we’ll sanity-check them before anything is cut. We’d rather spend ten minutes on that than build a door to a wrong number. Once the doors are made to your sizes, they’re made — bespoke items aren’t returnable, which is why we check.
Doors are delivered on a pallet — on our own transport across the North West, and further afield by pallet network. Tell us your postcode when you enquire and we’ll confirm delivery and price with the quote.
Store the doors flat or upright against a wall on their long edge, indoors or under cover, and leave the protective film on until the frame is fixed and the making good is done. Film left on in direct sun for months can be difficult to remove — take it off once the work around the door is finished.
If you’re fitting more than the occasional door, talk to us about a trade account. We work with builders, joiners, window companies and main contractors across the North West and supply well beyond it.

You’re saving the installation labour and the certification overhead. The size of the saving depends on the door and the complexity of the fit — ask us for both prices and decide from there.
The product carries its manufacturer guarantee. Installation-related faults aren’t covered on supply only, for the obvious reason that we didn’t install it. Our full 10-year guarantee applies to supply and fit.
Yes, from JL Enterprise Park, Rixton, Warrington WA3 6HG. You’ll need a van or a trailer with a flat bed and something to strap it down with — these are not roof-rack items.
Occasionally, for specific trade situations. Ask.
We can make a replacement unit to the same spec. Give us the door reference and the pane position.
Yes — aluminium sliding patio doors and aluminium windows are both available supply only.
Yes, the blinds are sealed inside the glazing unit at manufacture. See bi-fold doors with integrated blinds.
