A cracked pane in a roof lantern needs prompt attention because the glass is overhead. Send photos from Farnborough (GU11) and we'll tell you which it is — with the price agreed in writing before any work.

Why it happens
Thermal stress
Uneven heating across a pane, edge damage or partial shading can crack glass from the edge.
Spontaneous breakage
Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.

Do you need permission in England?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
