We offer the best selection of uPVC casement windows in London, supplied to your home within three weeks of the order date.

uPVC first became very popular in the 1980s when it began to be used as a replacement material for the mass of aluminium and steel windows that were previously installed across the UK. uPVC offered better value and an easier-to-maintain solution for homeowners.


Advances in manufacturing technology have seen the uPVC window evolve, and at Premier Windows, we can supply you with custom uPVC systems that offer the highest specifications and market-leading designs.

Our uPVC window system is #1 in Europe and the preferred system of architects, surveyors and government authorities. This is why:

  • A-rated as standard, with an amazing U-Value of 1.2 – ensuring our uPVC windows are eco-friendly and lead free
  • Thermal insulated, with noise-reduction panels that are exclusively designed in-house by us, dramatically reducing heat loss and external noise
  • Our windows will not discolour, even in the most extreme of weather conditions
  • Our windows are easy to clean and simple to maintain
  • We offer woodgrain-effect uPVC windows to suit a more traditional property.

Did you know? Choosing uPVC is an environmentally friendly choice, as the majority of end-of-life uPVC windows can be recycled over and over again to produce new windows.

Available casement window styles

We have a range of uPVC casement window styles and configurations to choose from. Find the right option to suit your home.

Glazed casement window
Casement windows are the most popular style in the UK and offer excellent all-round performance and functionality. Secured by Design accredited, these windows have successfully resisted opportunistic and sustained attacks in some of Britain’s crime hotspots. They’re safe, secure and energy efficient.
Glazed tilt and turn window
Tilt and Turn
Tilt and Turn windows are a popular, classic design that can be opened slightly to allow normal ventilation or fully for greater ventilation. Windows of this type can be ordered in unusual shapes with no compromise in security, performance or durability.
Glazed dual swing window
Dual Swing
The Dual Swing window has the appearance of a traditional sash window, but each sash reverses fully, allowing for exceptional ventilation. This window meets or exceeds all of today’s performance criteria and building regulations, and looks stunning too.
