Bifold doors are priced by the opening size and material. Get an indicative supply-and-fit figure below.
What affects bifold cost
- 1Size and panels
Priced by the opening width and number of panels — more glass and wider spans cost more.
- 2Material
Aluminium is the premium, slim-framed standard; uPVC is cheaper but bulkier. Both need good thresholds.
- 3The opening
If you're creating a new opening in a wall, add the structural beam and making good — a separate, significant cost.
Bifolds are a signature feature of a modern kitchen-diner and a strong selling point — but the doors are only half the job. If you're knocking through to the garden, the structural opening and making good can cost as much as the doors themselves.
