Current price examples
These examples come from the same pricing model used by the calculator. They are market estimates rather than binding installer quotations.
Like-for-like replacement matters
These figures assume an existing door opening. Converting a window into a door opening or creating a new structural opening can add substantially more because building work becomes part of the project.
Colour upgrades, triple glazing and enhanced security also move the final price.
Main cost factors
- Overall opening width
- White or coloured frame
- Double or triple glazing
- Whether structural opening work is required
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.
