Conservatory bifold door cost

We want to replace the old French doors on our conservatory with bifold doors to open it up more in summer. How much does a set of uPVC bifold doors typically cost, supplied and fitted?

"They normally work out £1000 per leaf supply and fit so for a 3 pane £3000 and so on but I would recommend ali instead of upvc"

"Hi Harry I would never recommend a Upvc bi fold as they have endless problems I would suggest aluminium and supplied and fitted is around £2500-£3000"

"UPVC bifold doors starts from £2900 supply&fit. Typically customers choosing aluminium bifold so price goes up."

"Depends on the width you have available once your double French doors are removed, bi-folds are okay in aluminium, I would not advise upvc. If the overall width is less than 2 metres bi folds will be, unless in two panes, to busy and the traffic door (main opener) will be to small. Dependant on the style of conservatory ie: dwarf wall style or full height glass, you could consider widening the aperture to take decent bi- folds, we have done this on several conservatories and the results are exceptional."
