Orangery Roof Lantern Repairs and Resealing

Orangery lanterns are larger and often sit within a perimeter roof with internal gutters, so leaks can come from the lantern, the perimeter roof or the junction between them. We repair all three, on timber and aluminium orangeries.

Why are orangery lanterns harder to repair?

Size and access. Larger lanterns may need a tower or scaffold, more glass units and more joints. Period orangeries may be listed. We plan access properly and include it in your written quote.

Do you need permission for this work?

Straightforward repairs don't normally need building regulations approval or planning permission. Replacing a whole lantern, changing its size or working on a listed building is different, and the rules vary by nation:

England

In England, replacing a roof lantern or rooflight is generally treated like replacing a window: the work must meet the Building Regulations (energy efficiency under Approved Document L, and safety glazing), and it's either done by an installer registered with a competent person scheme or notified to building control with an application. Enlarging the opening always needs a building regulations application. Replacing only the sealed glass units in an existing frame is usually treated as a repair rather than notifiable work, but the new glass should be no worse than before — if you're unsure, check with building control. We confirm in writing which route applies before any replacement.

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.

Wales

In Wales, building regulations are devolved and the Welsh Government publishes its own Approved Documents. Installing a new rooflight generally needs approval; for a replacement, the Welsh Government suggests using an installer registered with the relevant competent person scheme, or otherwise involving building control, and the new lantern must meet the Welsh energy-efficiency requirements. We confirm in writing which route applies before any replacement.

Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.

Scotland

In Scotland, the Building (Scotland) Regulations 2004 and the Technical Handbooks apply. Under schedule 3, replacing a rooflight including its frame doesn't need a building warrant but must meet the building standards in full; other work to a rooflight, including reglazing, must leave it no worse than before. New or enlarged openings are different and normally need a warrant. We confirm in writing which applies before any replacement.

Northern Ireland

In Northern Ireland, the Building Regulations (Northern Ireland) 2012 and the Technical Booklets apply, administered by your council's Building Control service. Replacement glazing, including rooflights, must meet the energy-efficiency requirements, and an application may be needed depending on the work. We check with Building Control and confirm in writing which route applies before any replacement.
