Everything London Homeowners Need to Know Before Buying | London Plastic Centre – Since 2006
Introduction
Imagine standing in your kitchen or living room. Sunlight pours in from above. The room feels bigger. Brighter. More welcoming.
That is what a roof lantern does.
Roof lanterns are replacing old skylights and conservatories across the UK. They add height, character, and natural light to flat roof extensions.
But one question stops many homeowners: How much does a roof lantern cost? And is it worth it?
This short guide gives you straight answers.
Part 1: What is a Roof Lantern?
A roof lantern is a glazed structure installed on a flat roof. It sits above the roofline, creating a “lantern” effect. Unlike flat skylights, roof lanterns have sloping glass panels on all sides.
Why homeowners love them:
- Maximum natural light (more than standard skylights)
- Architectural character – adds visual interest
- Makes rooms feel taller and more spacious
- Works on extensions, conservatories, and orangeries
Market trend: The UK roof lantern market is growing fast. Homeowners, architects, and developers now choose roof lanterns as a “must-have” feature for modern homes.

Answer: Most installations take 1-2 days. Day 1: remove old roof light (if any) and prepare opening. Day 2: install lantern, seal, and finish.
Q2: Do I need planning permission for a roof lantern?
Answer: Generally, no if it falls under permitted development rights. But listed buildings and conservation areas have restrictions. Check with your local council.
Q3: Are roof lanterns energy efficient?
Answer: Yes. Modern roof lanterns use double or triple glazing with thermal breaks. They meet current UK building regulations for thermal performance.

Q6: Can a roof lantern be installed on any flat roof?
