Roof lantern costs in the UK: Pricing, sizes and factors that change the budget

Roof lanterns have seen their popularity skyrocket in recent years, as more homeowners look for added light and thermal efficiency in their homes.

Protruding upwards from a flat surface, like a kitchen ceiling, extension roof, etc, roof lanterns can transform previously dreary spaces into bright, inviting rooms.

If you’ve joined the masses of homeowners up and down the country in deciding that roof lanterns are an excellent way to add comfort and value to your home, before frantically getting on Google and searching ‘how much do roof lanterns cost?’, we’ve put this blog together to help you out.

Truthfully, the cost of adding one of these architectural statements to your home isn’t a one-size-fits-all figure, with factors such as material, size and glazing all having an impact. Though roughly, you’re looking at a figure between £3,000 and £9,000, as per Checkatrade figures.

We’ll dive into this in more depth below, hopefully giving you a good idea of how much you can expect to pay for your new roof lantern.

How much do roof lanterns cost?

Roof lanterns in the UK usually sit between £3,600 and £9,000, but the cost of roof lanterns is influenced by more than just the size.

There are several ways in which to make your roof lantern bespoke, which will, of course, impact the bottom line.

What impacts the cost of a roof lantern

Several factors influence the installation prices of a roof lantern. Understanding them will help you plan your project with confidence.

Roof lantern size

The size of the roof lantern is one of the biggest price influencers. Bigger lanterns need more roof lantern materials, more glass panels, and longer labour. A larger roof lantern lets in an abundance of sunlight and can make a space feel even bigger thanks to the extra daylight hours and sense of openness.

Glass type and tints

Your choice of glass affects both the look and performance of your lantern. Options include double or triple glazing, which reduces heat loss but costs more, and tinted or solar glass, which controls solar gain and protects interiors, sometimes at a modest extra cost (it’s best to check with your installer).

Self-cleaning or toughened glass is ideal for high or hard-to-reach roofs, reducing maintenance with glass cleaner or soapy water.

Frame material

The material you choose will affect the cost, which is why we offer uPVC roof lanterns – they come at a lower cost, but offer better thermal performance than aluminium, with equally impressive strength and durability.

Installation complexity

Labour costs depend on your existing house, top of roof access, and whether the structure needs extra reinforcement. Installing an octagonal roof lantern, adding electric opening vents, or including extra ventilation features will also add to the final price.

Are roof lanterns worth it?

Roof lanterns are one of our most popular home improvement products we offer, owing to their ability to completely transform your living space below. How do they do this? We’ll explain.

Natural light

Roof lanterns provide extensive amounts of natural daylight, reducing reliance on artificial lighting and boosting the aesthetics of the space. As our country rightfully becomes more health-conscious, this has seen a spike in home improvement products that let the light in.

The health benefits of regular natural light include better sleep quality, improved productivity and a more pleasant mood, reasons that intertwine with the popularity of roof lanterns.

Energy efficiency

Modern lanterns, like those from Doncaster Trade Windows, use high-performance glazing, low-E coatings, and argon-filled units to maintain comfortable temperatures year-round. This helps reduce energy bills and keeps your home cosy in winter and cool in summer.

Customisation options

We offer forms of customisation to suit your specific needs. You can choose frame colours, glazing types, roof lantern blinds, retractable screens, or extra ventilation options, ensuring your lantern meets both functional and design goals.

FAQs

How does the size of the roof lantern affect cost?

The bigger the lantern, the more materials, glass panels, and labour required. A larger roof lantern also provides more sunlight and a sense of space, but naturally comes with a higher price.

Do roof lanterns require special cleaning?

Self-cleaning glass helps minimise maintenance. Otherwise, regular cleaning with soapy water or an extendable washing pole works well.

What frame materials are available?

We supply uPVC roof lanterns for affordability, thermal performance and durability.

Do square roof lanterns provide enough natural light?

Yes, square roof lanterns deliver an abundance of sunlight, transforming rooms into a bright, welcoming area and an exquisite feature.

What is the average cost of a roof lantern?

The average cost varies depending on the size of the roof lantern, the amount of roof covered, the number of glass panels, and any additional costs for glazing or extras.

Do roof lanterns come with a guarantee?

Yes, all Doncaster Trade Windows lanterns include a multi year guarantee covering the entire structure, giving peace of mind and protection for your investment.

What’s the difference between roof lanterns and flat roof lights?

Flat roof lights sit flush on the roof, while roof lanterns have a raised glass structure with thinner struts, providing extensive amounts of natural light. This clears up a common misconception and gives an accurate idea of each option.
