Regulations for jobs in Gainsborough
Replacement external doors in England should meet a U-value of 1.4 W/m²K under Approved Document L. Glass in doors and side panels below 1500mm is a critical location under Approved Document K, so it must break safely (toughened or laminated to BS EN 12600), be robust or in small panes, or be permanently protected. Doors into new homes also need to meet Approved Document Q for security, which is usually shown with PAS 24. Replacing a door that is more than half glazed is notifiable building work, self-certified through a competent person scheme or approved by building control.
