Every window on your order is listed separately on the quote with its size, layout, glass and finish, so you can check the whole job line by line before anything is put into production.

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 sizes can you make uPVC casement windows in?
Each window is made to the frame size you give us, within the limits of the profile and the weight the hinges are rated for. Very large or very small sashes are checked when we price your schedule and we tell you if a layout needs an extra mullion or transom.
