Ordering uPVC sliding sash windows for jobs in Cumbria
Most vertical sliders are ordered as straight replacements for timber box sashes. If the originals have horns, glazing bars or a particular meeting-rail height, note it on your schedule and the new windows are made to match.
For listed buildings and conservation areas, the council decides whether uPVC sash windows are acceptable. Check before you order; once made to size, the windows cannot be returned.

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.

uPVC sliding sash windows in Cumbria: common questions
Do you supply uPVC sliding sash windows across all of Cumbria?
Yes. We deliver throughout Cumbria, and the charge for your postcode is shown on the quote.

How do I get trade prices for Cumbria?
Request a quote with your sizes and postcode. Trade pricing applies once your account is open.
Why are sliding sash windows dearer than casements?
They use more profile, balances and hardware, and every window is set up individually. Our guide range reflects that.
Can you match the glazing bar pattern of existing windows?
Yes. Tell us the pattern for each sash, for example six over six or two over two, and whether you want bars that look applied or sit between the panes.
