Why Install a Rooflight in Your Kitchen?
Modern kitchens are more than cooking spaces — they're social, functional hubs. Adding a rooflight can:
Increase natural light (reduce need for artificial lighting)
Improve ventilation in high-moisture areas
Create a focal point in your extension
Enhance resale value with high-end finishes
“Adding a frameless skylight over your kitchen island is one of the most popular design moves in 2025. It draws in light without cluttering sightlines.”
— Anna Roberts, Interior Designer, RIBA Affiliate
Types of Rooflights for Kitchens (And Which Is Best)
Not all rooflights are created equal. Here's a quick breakdown of kitchen-suitable options:
✅ Fixed Frameless Rooflights
Best for flat roof kitchen extensions
Sleek, minimal look with no visible internal frame
High energy performance
Low maintenance
Top-rated for: Design-led renovations, daylight maximisation
✅ Opening Rooflights (Manual or Electric)
Provide extra ventilation while cooking
Useful for kitchens without extractor fans
Can be manually opened or operated via remote/rain sensors
Best for: Kitchens that require cross-ventilation or added airflow
✅ Roof Lanterns
3D, pyramid-style structures are ideal for large kitchen-diners
Impressive aesthetics, but more expensive
Best for: Large, open-plan kitchen projects with pitched or multi-angle ceilings

How to Choose the Right Rooflight for Your Kitchen
Here are the most important factors to consider:
1. Roof Type
Flat roofs suit frameless fixed rooflights or roof lanterns
Pitched roofs suit Velux-style opening roof windows
2. Room Function
If you cook daily, consider opening units for moisture release
If you have good extraction, a fixed model might suffice
3. Glazing Performance
Choose solar-control glass to reduce glare and overheating
Consider self-cleaning coatings for hard-to-reach installations
Opt for triple glazing in north-facing kitchens
4. Size & Placement
Centre over an island or dining table
Use multiple smaller units instead of one large panel for balance
"We chose a 1.2m x 2.4m frameless unit from Skylights.co.uk — it floods our kitchen with light and looks stunning from every angle."
— Matthew & Priya, homeowners in Brighton
Real Use Case Examples
