Trade uPVC flush sash windows in Hertfordshire

Ordering uPVC flush sash windows for jobs in Hertfordshire

Many period houses are in conservation areas or are listed. Planning rules for windows are set by the local council, so check with the planning department before ordering for those properties.

Woodgrain foils come in several shades of cream, white and colours. If you are matching existing windows on the same property, send a photo with your schedule and we will tell you which finish is closest.

Building regulations in England

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.

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.
