Our Classic uPVC sash windows make your home warmer, quieter and safer. The energy efficiency rating is A+. The corners of this window are stronger and last longer because of the mitred welded joints. The window frame has chamfered beading for a modern appearance. You can choose to upgrade with decorative horns, gold or chrome furniture, or glazing effects like Georgian bars.


We make our Elite uPVC sash windows to resemble traditional Victorian sash windows. They are A rated as standard. They have a deep bottom rail that is 105mm thick and a slimline rail that is 39mm thick where the panes meet. The profiles are butt-joined mechanically and the internal beading looks like you would find in a wooden sash frame. Elite uPVC sliding sash windows are good for homes in conservation areas. In these areas, you need special permission to change windows according to Article 4.

*Elite uPVC Sash windows are available in White Woodgrain and Cream Woodgrain only.

Our classic sash uPVC windows are very energy efficient with an A+ rating. Our Elite uPVC sash windows are also energy-efficient, with an A rating. Robust seals around each sash make them draught-free and weathertight. The sashes, frame and sills have a thermal break. This reduces heat or cold transferring between the sides of the frame. It also lessens heat loss and improves energy efficiency.

By switching to Anglian A-rated uPVC sash windows, you can save £184.25 on energy bills a year compared to pre-2002 uPVC double glazing.

*Source Glass and Glazing Federation. A typical detached house has 23.7m2 of windows. Based on replacing uPVC double-glazed windows with a 12-14mm sealed unit and gas central heating with A-Rated thermally efficient windows.

To keep your home and belongings safe, your new windows need to be strong and secure. That's why our Classic and Elite uPVC sliding sash windows have modern security features. You operate the locks with a key and the construction consists of strong, welded uPVC.

Classic uPVC Sash

Classic uPVC sliding sash windows have a security bar built into the windowsill. This bar keeps intruders from forcing open the window with tools or excessive force.

Elite uPVC Sash

Elite uPVC sliding sash windows have the Secured by Design seal. This police initiative states that homes meeting these standards have a 75% lower chance of break-ins. Two aluminium security blocks on the top sash prevent someone from forcing it open. Elite uPVC sashes are also reinforced with steel.

Our sash uPVC windows come with a 10-year guarantee. This guarantee is backed by insurance. Not all window companies offer this, so be on the lookout. The guarantee covers you if something goes wrong with your sash windows. We take care of the cost of repairing your windows, whether it is a partial or complete repair.

Classic uPVC sliding sash windows in White Woodgrain

“When we moved into our new house the original wooden sash windows were either broken or inefficient. Anglian had a good reputation and a fantastic range of sash windows to choose from. Our new windows are brilliant, they’re secure, they let in more light and they've really improved our home.”

Your Questions Answered by Us

How much do uPVC sash windows cost?

The price of uPVC sash windows can vary depending on what the company you choose includes. Look for a reputable supplier like Anglian that includes everything in the price. This is so you avoid finding any hidden fees later down the line.

Are sash windows more expensive?

uPVC sash windows cost more than other uPVC windows because of the way they're made. They have a special opening mechanism that requires extra engineering. If you have wooden sash windows and want a cheaper option, think about uPVC sash windows.

How does a uPVC sash window lock work?

A uPVC sash window lock locks the two sashes together in the middle of the window. Our sliding sash windows have key lockable cam locks that do this. You can open the windows a little for air by using the key-lockable limit stops on the top sash. These stops protect the mechanism and prevent the sashes from sliding past each other.
