What changes bifold door prices?

Opening width and panel count are the two biggest product variables. More panels mean more aluminium profiles, rollers, hinges and fabrication. Triple glazing, unusual finishes and threshold choices can add further cost.

Bifold price versus installation cost

This page shows the complete fitted-market estimate. The separate installation-cost guide focuses on how fitting and structural work influence the project. Creating or enlarging an opening can add considerably more than installing bifolds into a suitable existing aperture.

What affects the price?

Overall opening width
3, 4, 5 or more panels
Glazing and finish
Existing opening versus structural alterations

What “fitted” means here: supply, standard replacement installation and ordinary 20% VAT are included. Unusual access, scaffolding, structural repairs, planning/listed-building requirements and highly bespoke work can sit outside the standard estimate.
