Roof lanterns in Croydon: what is involved?
For Croydon homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
Jobs in Croydon are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Internal and external colours
- LED lighting in the plaster box
- Aluminium or uPVC systems
- Rectangular, square or bespoke sizes
- Solar-control or self-cleaning glass
- Classic look that suits period and modern homes
- Light from every angle across the day
Before you order: points to check
- Larger lanterns may need a steel or timber ring beam
- Plaster-box depth affects how the lantern looks from below
Do you need permission in Croydon?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Roof lanterns in Croydon: questions
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Do you fit roof lanterns in Croydon?
Yes. We survey and fit roof lanterns in Croydon and across Greater London. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Croydon?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
