Factors Affecting Rooflight Costs
Several factors influence the price of a rooflight, including:
-
Type of rooflight (fixed, opening, walk-on, modular, etc.)
-
Size and shape (larger or custom-shaped rooflights cost more)
-
Glazing options (double, triple, or self-cleaning glass)
-
Frame material (aluminium, uPVC, timber, etc.)
-
Additional features (solar control, remote operation, blinds)
-
Installation complexity (flat roofs vs. pitched roofs)
-
Brand and supplier
Now, let's explore the costs associated with different types of rooflights.
1. Fixed Rooflights
Fixed rooflights are the most affordable option as they do not open for ventilation. They are ideal for bringing in natural light while maintaining thermal efficiency.
-
Small fixed rooflight (600mm x 600mm): £250 – £500
-
Medium fixed rooflight (1000mm x 1000mm): £500 – £1,000
-
Large fixed rooflight (1500mm x 1500mm): £1,000 – £2,000
2. Opening Rooflights
Opening rooflights provide ventilation and are available in manual or electric options. Electric models tend to be more expensive due to motorisation and control systems.
-
Manual opening rooflight: £700 – £1,500
-
Electric opening rooflight: £1,500 – £3,000
3. Walk-On Rooflights
Designed for areas where people can walk over them, such as terraces and balconies, walk-on rooflights require reinforced glass for safety.
-
Small walk-on rooflight: £1,500 – £2,500
-
Large walk-on rooflight: £2,500 – £5,000+
4. Roof Lanterns
Roof lanterns are ideal for larger spaces and provide a visually striking effect, often used in extensions and orangery-style conservatories.
-
Small roof lantern (1000mm x 1500mm): £1,000 – £2,000
-
Medium roof lantern (1500mm x 2500mm): £2,000 – £4,000
-
Large roof lantern (3000mm x 4000mm): £4,000 – £8,000+
5. Modular Rooflights
Modular rooflights offer multiple glazing panels connected together, creating a sleek and modern look.
-
Basic modular system: £2,000 – £5,000
-
Bespoke modular system: £5,000 – £10,000+
Additional Costs to Consider
Choosing the right product is really important, but the cost of the rooflight isn't your only consideration. Installation and accessories also need to be priced into your skylight solution.
1. Installation Costs
Installation prices vary depending on the complexity of the job, access to the roof, and whether structural work is required. Prices may also vary depending on where you are in the country, and whether you're having the installation as a one-off job, or part of a larger project.
-
Standard installation: £500 – £1,500
-
Complex installation (structural changes required): £2,000 – £5,000+
2. Glazing Upgrades
Upgrading from standard double glazing to advanced glazing options affects the price, but can provide benefits like additional sound proofing, or easier cleaning, which may be of real benefit depending on the location of the rooflight installation.
-
Triple glazing: +£300 – £1,000
-
Self-cleaning glass: +£200 – £800
-
Solar control glass: +£300 – £1,200
3. Accessories & Customisation
Blinds and automatic features may not be required but should be considered in the pricing. Many units can be fully customised too, so if you can't find exactly what you need from off the shelf units, then it may be possible to create something bespoke.
-
Blinds (manual or electric): £100 – £800
-
Smart automation (rain sensors, remote control): £300 – £1,500
-
Bespoke shapes and sizes: Price varies significantly, often adding 20-50% to standard pricing
How to Get the Best Deal on Rooflights
Rooflights are an investment, but can make all the difference to your project. Here are some simple ways you can ensure you're getting a good deal.
-
Compare multiple suppliers – Prices vary, so get quotes from different providers.
-
Look for package deals – Some suppliers offer discounts on bundles (rooflight + installation).
-
Consider mid-range options – Avoid the cheapest products; invest in quality for better insulation and longevity.
-
Buy during off-peak seasons – Prices may be lower outside of peak home improvement months.
-
Check for government incentives – Some energy-efficient rooflights qualify for grants or reduced VAT.
Final Thoughts
The cost of rooflights depends on size, type, glazing, and installation requirements. While budget options exist, investing in high-quality materials and professional installation ensures durability, energy efficiency, and long-term savings.
Before purchasing, always get detailed quotes, consider additional costs, and choose a trusted supplier to ensure you get the best value for your money. If you need tailored advice or installation support, consulting a professional is the best approach to ensure a seamless, hassle-free experience.
