A uPVC casement window is a side-hinged style that swings outward — the most popular and versatile window style in UK homes. The hinge sits at the side of the frame so the entire sash opens fully, giving excellent ventilation and easy cleaning from inside. uPVC frames mean A-rated energy efficiency, zero maintenance and over 20 colour options, suiting everything from modern new-builds to period properties across the North of England.

Most homeowners we work with pay between £600 and £1,200 per window fully installed, depending on size, colour, glazing spec and any decorative options like astragal bars. We give you a free fixed-price quote with no hidden extras — the figure we write down is the figure you pay. Finance options are 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.

Significantly. Our uPVC casement windows are A-rated as standard, with argon-filled double-glazed units and warm-edge spacer bars that dramatically reduce heat loss compared with older single or early double glazing. Most customers see a noticeable drop in heating bills and a real difference in how warm rooms feel in winter — particularly in older period properties that have always been hard to heat.

Yes — you can choose from the full RAL colour palette as well as a wide range of authentic woodgrain foils. The most popular choices our customers make are Anthracite Grey, Chartwell Green, Cream and Slate Grey, all of which look fantastic on both modern and period properties. 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 uPVC casement window comes with a 10-year manufacturer guarantee covering the frames, sealed glass units and hardware, plus a 5-year 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.
