Sliding rooflights for Caterham: the essentials
Our sliding rooflights service in Caterham covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for sliding rooflights include staircases that rise to a roof terrace.
From Caterham to Coulsdon, Purley and Redhill, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Anthracite, black or RAL frames
- Integrated balustrade on some ranges
- Electric drive with safety edge
- Double or triple glazing
- Rain sensor
- Daylight down the stair when closed
- Replaces a dormer or stair enclosure on some roofs
Before you order: points to check
- Weight and point loads need a structural check
- Electric units need a dedicated supply and commissioning
Planning, building control and Caterham
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about sliding rooflights in Caterham
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
How do I book a survey in Caterham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Caterham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
