Flush sash frames are deeper than standard casements, so check the reveal depth and any existing timber sub-frame before you finalise sizes, and note it on your schedule.
Regulations for jobs in Harpenden
Replacement windows in England should meet Approved Document L: a U-value of 1.4 W/m²K or a Window Energy Rating of band B. Approved Document F expects background ventilation to be no worse than before, which usually means trickle vents. Glazing in critical locations must break safely, be robust or in small panes, or be permanently protected under Approved Document K, which in practice usually means toughened or laminated safety glass. Rooms that need an escape route may need an escape window under Approved Document B. Replacing windows is notifiable building work: the installer self-certifies through a competent person scheme such as FENSA or Certass, or the work goes through building control.

What is the difference between flush sash and standard casement windows?
On a standard casement the sash sits proud of the frame. On a flush sash it closes into the frame so both faces are level, which gives the look of a traditional timber casement.
