Daylight across Greater London
Daylight in Greater London runs from about 7 h 50 min in December to 16 h 38 min in June, with the noon sun at roughly 15° and 62° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.
Approvals in England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
A new or wider opening in England needs Building Control approval for the structural work as well as compliance for the door itself under Approved Documents L and K. Expect structural calculations, a steel beam and, where a party wall is involved, notices under the Party Wall etc. Act 1996.
