Building regulations in England

Replacement rooflights and roof lanterns in England should meet a U-value of 2.2 W/m²K under Approved Document L. A lantern in a new extension is covered by the extension's own building regulations approval. Replacing a glazed or polycarbonate conservatory roof with a solid roof usually takes the conservatory out of the exemption, so building control approval is normally needed.

Before anything goes into production you get a written order acknowledgement with sizes, finishes and handing for every item. Check it carefully, because made-to-measure items cannot be returned if the sizes were wrong.
