Sliding rooflights for Swanley: the essentials
Our sliding rooflights service in Swanley 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Swanley, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
Jobs in Swanley 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
- Box (glazed sides) or flat sliding lid
- Double or triple glazing
- Integrated balustrade on some ranges
- Electric drive with safety edge
- Anthracite, black or RAL frames
- Daylight down the stair when closed
- Replaces a dormer or stair enclosure on some roofs
Things we check at survey
- Needs space on the roof for the lid to slide clear
- Electric units need a dedicated supply and commissioning
Consents for sliding rooflights in Swanley
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Questions about sliding rooflights in Swanley
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
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.
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.
Is the survey in Swanley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Swanley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
