How Much Do Steel Windows Cost?
Steel windows are bespoke, so there is no fixed price list — every project is made to survey. But the cost is driven by a predictable set of factors. Understanding them helps you budget and compare quotes fairly.
What drives the price
The biggest variables are the section type (heritage W20 vs thermally broken W50), the glazing specification (single, double or triple, plus any acoustic or specialist glass), the overall size and number of opening lights, and the finish.
Doors, shaped or arched geometry, and fire-rated requirements add to the engineering, and therefore the cost. Survey, delivery and installation are also part of a complete, fitted price.
Why bespoke steel sits above off-the-shelf
Each frame is fabricated to your exact aperture, hot-dip galvanised, finished in your chosen RAL colour and installed by the team that made it. That craftsmanship is why steel costs more than a standard uPVC or aluminium unit — and why it lasts.
Many customers tell us we are competitive against other steel specialists on both price and delivery time, so it is always worth comparing like-for-like steel quotes.
Getting an accurate quote
The fastest way to a real figure is to share your sizes, rough quantities, target dates and any drawings or elevations. From there we can return a considered estimate rather than a guess.
If you are at an early stage, even approximate opening sizes and photos are enough for us to give useful guidance.
Frequently asked
- Can you give a price per window?
- Not reliably — steel is bespoke, so price depends on section, glazing, size and finish. Share your sizes and we'll prepare an accurate estimate.
- Is steel worth the extra cost?
- For the slimmest sightlines, longevity and character, most buyers think so. It is a long-term investment in the property.
