Stock Size Windows

Order your stock size windows today!

Here at Just Value Doors, we supply a carefully selected range of stock size uPVC windows in popular UK standard sizes, offering an excellent balance of quality, performance and value. Our stocked windows are manufactured in the UK and built to the same high specification as our bespoke uPVC windows, ensuring there is no compromise on durability, energy efficiency or compliance.

By standardising sizes, we’re able to reduce manufacturing complexity and pass those savings directly on to you. With prices starting from just £LOWEST_PRICE incl VAT, our stocked uPVC windows can offer savings of up to 40% compared to made-to-measure alternatives, making them an ideal choice for cost-conscious home improvement projects.

All stocked windows are A-rated for energy efficiency, CE marked, and double glazed as standard, helping to improve thermal performance and reduce heat loss. Secure locking systems, quality hardware and long-lasting materials are included as standard, ensuring reliability and peace of mind whether you’re replacing existing windows or renovating a property.

Stocked uPVC windows are particularly well suited to replacement projects where standard sizes are appropriate, offering a simple and cost-effective alternative to bespoke manufacturing. If you require a specific size, configuration or design, we also offer a full made-to-measure uPVC window service, allowing you to customise every detail to suit your home.
