Natural light is a crucial element in any home, transforming spaces by making them feel bigger, brighter, and more inviting. If you’re looking for an effective way to introduce more daylight into your home, fixed roof lights could be the perfect solution.
Unlike traditional windows, fixed roof lights are positioned in the roof, allowing natural light to flood into a space from above.
Whether you’re planning a new extension, upgrading a dark room, or improving your home’s energy efficiency, rooflights provide a practical and stylish option.
This guide will walk you through everything you need to know, from the benefits of fixed roof lights to how to choose the right one for your home.

What are Fixed Roof Lights?
A fixed roof light is a non-opening rooflight designed to bring natural light into a space without additional ventilation. Unlike opening rooflights, these are sealed shut, making them an excellent option for areas where ventilation isn’t a priority but maximising daylight is essential.
Fixed roof lights are typically installed in flat or pitched roofs and can be made from various materials, including aluminium and UPVC. With their minimalist frames and high-quality glazing, they offer sleek aesthetics and excellent thermal performance.
Benefits of Installing Fixed Roof Lights
Adding fixed roof lights to your home offers several advantages:
Maximum Natural Light
Brighten up dark spaces and create a more open, airy feel.
Enhanced Energy Efficiency
Reduce reliance on artificial lighting, cutting energy bills.
Improved Aesthetics
A stylish, modern feature that enhances any space.
Low Maintenance
No moving parts mean minimal upkeep.
Better Insulation
Triple-glazed options improve thermal efficiency, keeping your home warmer in winter and cooler in summer.
Cost-Effective
More affordable than opening rooflights while delivering the same amount of light.
Comparison with Other Lighting Solutions
Compared to traditional windows, fixed roof lights allow for more even light distribution throughout a space.
Unlike artificial lighting, they provide a natural ambience that enhances mood and reduces electricity costs.
Additionally, compared to opening rooflights, fixed roof lights require less maintenance and offer improved insulation due to their fully sealed design, making them a more energy-efficient choice in colder months.

How to Choose the Right Roof Light for Your Home
When selecting a roof light, consider these key factors:
- Room Purpose – If ventilation is needed, consider an opening rooflight instead.
- Glazing Options – Double or triple glazing impacts energy efficiency and insulation.
- Frame Material – Aluminium offers durability, while UPVC is cost-effective.
- Size & Placement – Position your rooflight to maximise natural light in your space.
- Budget – Fixed rooflights tend to be more affordable than opening options or roof lanterns.
Key Considerations Before Buying
Building Regulations
Before installing a rooflight, it’s essential to check local building regulations. While most rooflights do not require planning permission, factors such as the size, location, and visibility from public roads can influence compliance. If your property is in a conservation area or a listed building, additional permissions may be required.
Weather Resistance
The UK weather can be unpredictable, with heavy rainfall, strong winds, and fluctuating temperatures. Choosing a rooflight designed for durability and equipped with weather-resistant seals will help protect your home from leaks and drafts. Opt for high-quality materials like aluminium frames and triple-glazed glass for added resilience.
Self-Cleaning Glass
Maintaining a roof light can be challenging, especially if it is positioned in an inaccessible area.
Self-cleaning glass features a special coating that breaks down dirt and grime when exposed to sunlight, allowing rainwater to wash it away. This feature can reduce maintenance efforts and keep your roof light looking pristine year-round.
Installation Costs
The cost of installing a rooflight varies depending on factors like size, glazing type, and complexity of the installation. While DIY installation is possible for smaller, simpler models, professional installation ensures correct sealing, alignment, and compliance with building regulations. Investing in expert fitting can prevent costly issues such as leaks and heat loss in the future.
Common Mistakes to Avoid
- Choosing the Wrong Size – A rooflight that’s too large can lead to excessive glare and heat gain, while one that’s too small may not provide the desired lighting effect.
- Ignoring Thermal Efficiency – Not all rooflights offer the same insulation properties. Triple-glazed options provide better performance in colder months.
- Overlooking Placement – Poor positioning may result in uneven lighting or unwanted shadows.
- Not Checking Compliance – Some homes may require additional structural reinforcement before installing a rooflight.

A high-quality rooflight, such as a triple-glazed option, can last 20+ years with proper maintenance.
Does a rooflight make a room cold?
