Ordering uPVC casement windows for jobs in Hertfordshire
Casements cover most replacement work in the UK because almost any opening can be laid out with a mix of side-hung, top-hung and fixed lights. You give us the sizes and opener layout and each window is made to that schedule rather than chosen from a list of standard sizes.
If the property needs background ventilation, tell us which windows take trickle vents and we fit them in the frame head before dispatch, which saves routing them on site.

Delivery across Hertfordshire
We deliver to sites and yards in Hertfordshire as part of our mainland delivery service. Delivery is priced on the quote, so you know the full cost before you place the order.
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.
We do not start manufacturing until you have approved the order acknowledgement. It repeats each size, colour and opening direction so you can check it against your survey.

How do I get trade prices for Hertfordshire?
Request a quote with your sizes and postcode. Trade pricing applies once your account is open.
Are the windows supplied glazed?
Windows can be supplied glazed or with the units packed separately for site glazing. Tell us which you prefer when you order; larger windows are often easier to handle with the glass out.
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.
