Choosing the right windows for your home or project is a big decision. It affects not only the look of your property but also its energy efficiency, security, and long-term maintenance. Two popular options are aluminium and timber windows. Both have their strengths, but understanding the cost differences can help you make the best choice. In this post, I will walk you through the key factors affecting the price of aluminium and timber windows, so you can decide with confidence.
Understanding Aluminium and Timber Cost Differences
When comparing aluminium and timber windows, the initial price is often the first thing that catches your eye. Aluminium windows tend to have a higher upfront cost than timber. This is mainly because aluminium frames require more complex manufacturing processes and materials. Timber, on the other hand, is a natural material that can be sourced and worked on with traditional carpentry skills, which sometimes lowers the initial price.
However, the story does not end there. Timber windows often need more maintenance over time, such as sanding, painting, or staining, which adds to the overall cost. Aluminium windows are low maintenance and resistant to rust, warping, and cracking, which can save you money in the long run.
To give you a clearer picture:
Aluminium windows typically cost between £400 and £700 per window, depending on size and style.
Timber windows usually range from £300 to £600 per window, but maintenance costs can add up.
Keep in mind that prices vary based on the quality of materials, glazing options, and installation fees. It’s always a good idea to get detailed quotes from local suppliers and installers.

Factors That Influence Aluminium and Timber Cost
Several factors affect the cost of both aluminium and timber windows. Understanding these can help you budget better and choose the right option for your needs.
Material Quality
Aluminium: Higher-grade aluminium alloys and powder-coated finishes increase durability and price.
Timber: The type of wood matters. Hardwood like oak or mahogany costs more than softwood like pine.
Window Style and Size
Larger or custom-shaped windows cost more to produce and install.
Complex designs with multiple panes or decorative features add to the price.
Energy Efficiency
Double or triple glazing improves insulation but raises costs.
Both aluminium and timber frames can be fitted with energy-efficient glass, but timber often offers better natural insulation.
Installation
Professional installation is crucial for performance and longevity.
Labour costs vary by region and complexity of the job.
Maintenance
Timber windows require regular upkeep to prevent rot and decay.
Aluminium windows need minimal maintenance, which can save money over time.
By considering these factors, you can better understand the total cost of ownership, not just the initial price tag.
Can you put burglar bars on aluminium windows?
Security is a top priority for many homeowners. If you are considering aluminium windows, you might wonder if you can add burglar bars for extra protection. The good news is yes, you can.
Aluminium frames are strong and can support the installation of burglar bars without compromising the window’s integrity. Many security companies offer custom burglar bars designed to fit aluminium windows perfectly. These bars can be powder-coated to match the frame colour, maintaining the aesthetic appeal of your home.
Adding burglar bars to timber windows is also possible, but the installation process can be more complex due to the softer nature of wood. Aluminium’s strength makes it a more straightforward choice for enhanced security features.

Comparing Long-Term Value: Aluminium vs Timber Windows
When deciding between aluminium and timber, it’s important to think beyond the initial cost. Long-term value includes durability, maintenance, energy savings, and resale appeal.
Durability: Aluminium windows are highly durable and resistant to weather damage. Timber windows can last a long time if well maintained but are more vulnerable to moisture and pests.
Maintenance: Aluminium requires little upkeep, while timber needs regular painting or staining.
Energy Efficiency: Timber naturally insulates better, but modern aluminium windows with thermal breaks and double glazing can match or exceed timber’s performance.
Aesthetic Appeal: Timber offers a classic, warm look that suits traditional homes. Aluminium provides a sleek, modern appearance.
Resale Value: Both types can add value to your property, but well-maintained timber windows may appeal more to buyers looking for character.
By weighing these factors, you can choose the window type that fits your budget and lifestyle best.
Making the Right Choice for Your Home
Choosing between aluminium and timber windows depends on your priorities. If you want a low-maintenance, durable option with a modern look, aluminium is a strong contender. If you prefer a traditional style with natural insulation and don’t mind regular upkeep, timber might be the way to go.
For those in Sussex, Kent, Surrey, and the South East, it’s worth considering local climate and suppliers. Coastal areas, for example, can be tough on timber due to humidity and salt air, making aluminium a more practical choice.
