Correspondent 3rd Mar, 2025   0

New windows in a home (or office, or chill spot) are one of those investments that are absolutely worth your time and money. With plenty of designs and materials to pick from trying to figure out how much homeowners can expect to spend can be a little confusing, if not something most might just want to avoid altogether!

Why Replace Your Windows?

Before we get you to spend your money — so what is the grand plan to replace all windows? I mean new windows keep out the cold, so energy efficiency, and new windows deter break-ins, so a safely secured home!

And then, there’s noise reduction. Because everyone wants a nice quiet house, and oh — did I say there’s the whole curb appeal thing… Because a fresh new set of windows for the twenty-first century will go a long way to up the rest of your real estate!

Types of Windows and Their Costs

The cost of replacement windows will depend on the different factors that are more thoroughly discussed in this WhatCost guide on double glazing windows cost, these are: window style and window frame material. Let’s see what we have.




1. Casement Windows

They have one or more panes that open outwards just like a door does using a hinge.


  • Cost: £300–£800 per window.
  • Best For: Energy efficiency and views that are not obstructed.
  • Pros: Not hard to operate and gives excellent ventilation.

2. Sash Windows

That’s the part of the window that the panes are fitted to — only has one or two sashes that can be vertically slid to open and close.

  • Cost: £500–£1,000 per window.
  • Best For: You get that classic aesthetic like in older homes.
  • Pros: So much charm and unmatched heritage appeal.

3. Bay Windows

So these combine three windows, which project outside of the home. So you get the feeling as if you have a little more space and letting in lots of light!

  • Cost: £1,000–£2,500 per window.
  • Best For: Lots of character and space.
  • Pros: It gives you that natural, bright light and amazing to-die-for views.

4. Tilt-and-Turn Windows

People love the ability to keep the windows tilted in for a breeze and cleaning them is a snap with the full-swing sash operation.

  • Cost: £400–£900 per window.
  • Best For: Those who want function and style — not so much.
  • Pros: No fuss cleaning and excellent airflow.

5. Fixed Windows

Fixed windows or picture windows. These do not open but give you a nice and clean large space of glass.

  • Cost: £200–£500 per window.
  • Best For: Outdoor views in living rooms or offices.
  • Pros: Very low maintenance and great energy efficiency.

Material Choices and Their Impact on Costs

The window frame material plays a huge role (and impact) on your pocket.

  • uPVC: By far the fairest option in terms of price and will cost you between £300 – £800 per window. It is also the most low maintenance and offers good energy efficiency.
  • Timber: The best options are around £800 – £1,500 per window. They are great for period properties but the most high maintenance.
  • Aluminium: Most modern and durable look with an average cost of £500 – £1,200 per window.
  • Composite: All benefits of the above. The cost for one starts from £800. They are protected from the elements, durable and energy efficient.

Final Thoughts

You really need window replacement because after all — your house is your bestie! You want comfort, aesthetics and energy efficiency — there are some windows that will give you exactly that. Whilst costs can greatly vary, understanding what can affect this and what option might be suitable for your build will mean a happier household and bank balance.
