VELUX® Escape & Access Skylights

Loft Conversions need Escape Planning
*Picture by Velux

Since the 2008 building regulations change Escape and Access windows are no longer a required in loft conversions.

More emphasis is now placed on access via stairs.

Escape in Case of Fire

The loft staircase will be the principal escape route in the event of a fire and stairs must discharge to a suitable final exit, normally a front or rear door.

Alternative Means of Escape

New loft room(s) should have an window or skylight designed for escape or rescue. This window needs to be easily accessible, large enough to climb through, and close to eaves level. This will assist rescue from an external source, e.g. fireman's ladder.
