An aluminium casement window is a side-hinged window built on a slim, powder-coated aluminium frame. Because aluminium is so strong, the frames can be far narrower than uPVC — so you get more glass, more natural light and a clean, contemporary sightline for the same opening. Modern systems are thermally broken (a polyamide barrier inside the frame stops heat escaping), giving excellent energy performance alongside outstanding durability, security and a virtually maintenance-free finish that won’t warp, flex or fade.

Aluminium casement window prices depend on the size, colour, glazing spec and configuration you choose. Aluminium is a premium frame material — slimmer, stronger and longer-lasting than uPVC — and right now you can save up to 40% on your project. We give you a free fixed-price quote with no hidden extras, and finance is available to spread the cost over up to 4 years.

From order to fitting day we’re typically 2–4 weeks — we’ll confirm an exact date at survey. The install itself is usually 1 to 2 days for a typical job of 4–6 windows, all by our own in-house team — never subcontractors. We arrive on time, lay dust sheets through the house, work cleanly, and tidy up properly at the end of each day. Larger whole-house installs add another day or two and you’ll have a clear day-by-day schedule before we start.

Yes — every installation comes with a CERTASS certificate of compliance, posted to you after the job is signed off. This certificate proves your new windows meet current Building Regulations for energy efficiency and is essential paperwork if you ever sell your home. There’s no extra charge and no chasing required.

Yes. Our aluminium casement windows are thermally broken as standard — a polyamide barrier runs through the frame to stop heat escaping — and come with argon-filled double glazing and warm-edge spacer bars. Triple glazing is available for the very best performance. Most customers see a noticeable drop in heating bills and a real difference in how warm rooms feel in winter, alongside far less condensation than older single or early double glazing.

Yes — aluminium is powder-coated, so you can choose from virtually the entire RAL colour palette in matt, satin or textured finishes. You can even specify dual-colour frames — one shade inside to suit your décor and another outside for kerb appeal. The most popular choices are Anthracite Grey, Matt Black, Slate Grey and White. We’ll bring samples to your free survey so you can hold them up against your home.

We cover Yorkshire (West, South, North and East), Lancashire, Merseyside and Cheshire — from Leeds to Liverpool, York to Chester, Hull to Crewe, and everywhere in between. If you’re not sure whether we reach your postcode, fill in your details below and we’ll confirm within minutes — if it’s anywhere in the North, the answer is almost always yes.

Every aluminium window comes with a comprehensive manufacturer guarantee — up to 25 years on the powder-coated frame — covering the frames, sealed glass units and hardware, plus a workmanship guarantee on the installation itself. Because we’ve been trading from our Halifax base since 2007 and serving Yorkshire, East Yorkshire, Lancashire, Merseyside and Cheshire for nearly 20 years, you know we’ll still be here if you ever need us.

For a straightforward like-for-like replacement, planning permission is almost never required — it falls under permitted development. If your home is in a conservation area, listed, or you’re changing the style or opening size, there may be additional considerations. We’ll advise honestly during your free home survey and point you in the right direction if anything needs checking with your local council.
