Replacement windows vary in cost, ranging from £600 to £3,600 per window. This fluctuation is influenced by factors like materials, styles, and installation. The type of material, whether it’s uPVC, aluminium, timber, or composite, plays a pivotal role in determining the expense. Different styles, be it casement, sash, or bay windows, also contribute to the overall cost.
Additionally, installation complexities influence the final price tag. Understanding these factors is crucial when considering window replacement, ensuring that your investment aligns with your preferences, functionality needs, and budget constraints for a well-informed and cost-effective home improvement.
The Cost Of Replacement Windows By Frame
Check replacement windows’ cost variations based on different frame materials.
1. Cost of uPVC window frames
The prevalent form of double-glazing windows and uPVC window frames exhibited impressive durability and were crafted to insulate homes and diminish noise. With proper upkeep, they boast a longer lifespan compared to other frame varieties. Nevertheless, it’s worth noting that uPVC windows have drawbacks, as their lightweight material can lead to a tendency to sag over time.
In addition to their appealing advantages, uPVC windows are relatively economical – indeed, they stand out as the most budget-friendly frame option. The table below delineates the average costs for uPVC casement windows, exclusive of installation.
Window size (mm) | Cost per Window |
600 x 900 | £300 to £500 |
900 x 1200 | £500 to £750 |
1200 x 1200 | £800 to £1100 |
2. Cost of aluminium window frames
Despite being pricier than uPVC, aluminium frames showcase remarkable durability and lightweight nature, contributing to enhanced security and reduced noise. These frames are known for their stylish and aesthetically pleasing qualities, making them a suitable option for those seeking to enhance the visual appeal of their homes. However, it’s important to note that aluminium frames are less effective insulators, and they may not retain heat as efficiently as other materials, resulting in a typically lower energy efficiency rating compared to uPVC.

Window size (mm) | Cost per Window |
600 x 900 | £650 to £900 |

3. Cost of timber window frames
Timber frames have emerged as the most high-priced frame types. Nevertheless, they hold the potential to augment your home’s value and stand out as the most stylish frame option. When well-maintained, timber frames boast an impressive lifespan of 50 years or more.
Renowned for their natural insulation properties, timber frames excel in regulating the temperature within your home. They come in various finishes, offering the choice between hardwood and softwood.
It’s important to note that timber frames demand substantial maintenance to ward off warping and rotting over time, necessitating regular tasks such as painting or staining.

4. Cost of composite window frames
Composite frames share a similarity with timber frames in terms of costliness. This stems from composite windows comprising an aluminium frame clad with timber. While demanding less maintenance, they retain the elegant appearance characteristic of timber frames. It’s worth noting, however, that similar to aluminium frames, composite frames may not retain heat effectively.
