Velux windows are a popular choice for UK homes, especially for lofts, attic rooms, and extensions. These roof windows bring natural light, fresh air, and a modern look to any space. However, before installing one, homeowners often want to understand how much a Velux window costs and what factors affect the final price. It explains Velux window costs in the UK in a clear and simple way, helping you make the right decision for your home and budget.
What Is a Velux Window?
A Velux window is a type of roof window designed to fit into sloping roofs. Unlike standard vertical windows, Velux windows are installed directly into the roof, allowing sunlight to enter from above. They are commonly used in loft conversions, attic bedrooms, home offices, and dark spaces that need more daylight.
Velux is a trusted brand in the UK, known for quality materials, long lifespan, and energy-efficient designs. Because of this, Velux windows are often more expensive than basic roof windows, but they offer better performance and durability.
Average Velux Window Costs in the UK
The cost of a Velux window in the UK depends on the window type, size, glazing, and installation requirements. On average, homeowners can expect the following price ranges. A standard Velux roof window usually costs between £250 and £600 for the window alone. Larger windows or special designs can cost £800 or more. Installation costs normally range from £400 to £1,000, depending on the complexity of the work. In total, the average installed cost of a Velux window in the UK is usually between £700 and £1,600 per window.
Factors That Affect Velux Window Costs
Several important factors influence how much you will pay for a Velux window. Understanding these can help you plan your budget more accurately.
Window Size and Type
Velux windows come in many sizes, from small roof lights to large panoramic windows. Larger windows cost more due to extra materials and labour. Standard centre-pivot windows are usually the most affordable, while top-hung or balcony-style Velux windows are more expensive.
Glazing Options
The type of glazing has a big impact on price. Double-glazed Velux windows are standard and suitable for most homes. Triple glazing costs more but offers better insulation, noise reduction, and energy efficiency. Special glazing, such as noise-reducing or sun-control glass, also increases the cost.
Manual or Electric Operation
Manual Velux windows are cheaper and easy to use if installed within reach. Electric or solar-powered Velux windows cost more but are ideal for high ceilings or hard-to-reach areas. These models often include rain sensors that automatically close the window when it rains.
Roof Type and Condition
The type of roof affects installation costs. Installing a Velux window in a tiled roof is usually cheaper than in slate or metal roofing. If the roof structure needs reinforcement or repairs, this will increase the overall cost.
Installation Complexity
A simple replacement of an existing Velux window is quicker and cheaper than cutting a new opening in the roof. Creating a new opening requires more labour, structural work, and internal finishing, which raises the price.
Velux Window Installation Costs Explained
Installation costs vary depending on the job size and location in the UK. Labour charges usually include cutting the roof opening, fitting the window, adding flashing, and making the interior weather-tight.
Replacement Installation Costs
Replacing an old Velux window with a new one is the most affordable option. This usually costs between £400 and £600 for labour, as the opening already exists.
New Installation Costs
Installing a new Velux window where there was no window before costs more. Labour prices for this work often range from £700 to £1,000, depending on roof access and internal finishing needs.
Internal Finishing Costs
After installation, you may need plastering, painting, or decorating around the window. This can add £150 to £400 to the total cost, depending on the finish you want.
Energy Efficiency and Long-Term Savings
Although Velux windows can seem expensive at first, they can save money over time. Modern Velux windows are designed to improve insulation and reduce heat loss. This helps keep your home warmer in winter and cooler in summer.
Energy-efficient glazing reduces heating bills and improves comfort. Some homeowners also notice lower lighting costs because Velux windows provide more natural daylight throughout the day.
Planning Permission and Building Regulations
In most cases, installing a Velux window does not require planning permission, especially if it does not change the roof shape. However, if your home is in a conservation area or is a listed building, you may need approval.
Building regulations approval is usually required. This ensures the window meets safety, insulation, and ventilation standards. Professional installers normally handle this as part of the job.
Choosing the Right Velux Window for Your Home
Selecting the right Velux window is about balancing cost, function, and comfort.
For Loft Conversions
Top-hung or centre-pivot windows are popular for lofts. They provide good ventilation and clear views. Double or triple glazing is recommended for better insulation.
For Bathrooms and Kitchens
Moisture-resistant Velux windows with ventilation features work best in bathrooms and kitchens. Electric or solar options are useful if the window is out of reach.
For Living Spaces
Larger Velux windows or multiple units can transform living spaces with natural light. While more expensive, they add value and improve the overall look of your home.
Are Velux Windows Worth the Cost?
Velux windows are a long-term investment. They improve natural light, ventilation, and energy efficiency while increasing property value. Although the initial cost may be higher than standard roof windows, their durability and performance often justify the price.
Many UK homeowners choose Velux because of the brand’s reputation, strong warranties, and high build quality.
How to Save Money on Velux Window Costs
There are ways to reduce the overall cost without compromising quality.
Choosing standard sizes instead of custom options helps keep prices lower. Installing during other roof work, such as a loft conversion or roof repair, can reduce labour costs. Getting multiple quotes from experienced installers also helps ensure fair pricing.
