Bifold windows cost

Roughly how much do bifold windows cost? And once installation is factored in, does the material we choose really make much of a dent in the cost of bifold windows?

"Bifold windows in the UK typically cost between £900 and £3,800 for supply only, and around £1,200 to £3,500 or more once installation is included. The material you choose does affect the price, with uPVC being the cheapest, aluminium the most popular mid-range option, and timber the most expensive. However, in most cases, the overall cost is influenced more by the size of the window and the complexity of the installation than the material itself."
