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?

"Hi Harry - unfortunately its a bit of a 'how long is a piece of string' type question.

A fitter would need to know the size and specification you want to give you a ballpark. When you say you had French doors before. Did you have a couple of side panels then which your hoping to open up with bifolds?

If your local to our area we could quote for you.

A very rough guide might be £3000-£5000 but this is kind of a shot in the dark given the lack of info.

Thanks

"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."
