New Windows Grant for Casement Windows

uPVC casement windows and flush fit windows refer to two distinct styles of windows, often made from unplasticised polyvinyl chloride, a durable and heat-resistant plastic.

uPVC Casement Windows: the standard style in which the window sash opens outward horizontally from the side, typically with a single or double hinge. The frame protrudes outwards from the window casing, adding depth. This style is popular because it allows unobstructed views and maximises ventilation.

Flush Fit Casement Windows: the sash sits flush (level) with the frame, giving a smooth, flat appearance. The flush design offers a sleek, streamlined look that often fits better with modern architecture or conservation areas where traditional timber designs are required. They provide the same functionality but with a different aesthetic.

In summary, the difference is primarily aesthetic. If you still have single glazed casement windows, you may qualify for grants to upgrade to double or triple glazing, improving efficiency even further. You can explore our flush windows for more detail.

Casement windows are a popular type of window commonly found in homes. They are hinged on one side and open outward, typically operated with a crank handle or lever. When the window opens, it functions like a door, allowing for maximum ventilation and easy access for cleaning.

These windows are versatile and functional. They can be installed as individual windows or grouped together to form a bay or bow window, and are available in uPVC, wood and aluminium. One key advantage is their excellent energy efficiency: when closed, they create a tight seal, minimising air leakage and helping to improve insulation and EPC rating.

Due to their single-panel design, casement windows offer unobstructed views. In terms of security, the hook-shaped locks within the frame make them highly resistant to forced entry when properly secured. They come in different opening styles, including side-hung and top-hung. Maintenance is straightforward, as they can be cleaned from both inside and outside.

Eligibility for replacing single glazed windows and window replacement support can depend on several factors, including your household income, the condition of your existing windows, and whether you're experiencing issues such as poor window locking or general disrepair. In many cases, funding is administered through local authorities, so availability can vary depending on where you live. Your funding options may also vary depending on your circumstances, how urgently new windows are needed, and whether the work qualifies as energy-efficient upgrades designed to reduce heat loss and lower energy bills.

Installing high-performance casement windows is one of the best ways to improve your home, helping keep more heat inside for a warm home and reducing energy waste. While we don't install heat pumps or run any grant schemes ourselves, many homeowners benefit from draught proofing initiatives such as the Affordable Warmth Scheme.
