If you’re researching new windows for your home in Knutsford or across Cheshire, you’ve probably come across a lot of unfamiliar terms, casement, sliding sash, tilt and turn, flush sash. Each style suits a different type of property and budget, and choosing the right one makes a real difference to both the look and performance of your home. This guide covers every major uPVC window style, realistic 2026 pricing, and what to consider before you get quotes, for homeowners across Knutsford, Cheshire, Staffordshire and Shropshire.

uPVC Casement Windows

Casement windows are the most popular and versatile window style in the UK, and the style we install most often using REHAU uPVC profiles. They open outward on a hinge, either top-hung or side-hung, and suit almost any property, modern or traditional.

REHAU windows achieve the highest BSI rating available, meaning wind, water and extreme weather won’t affect your day-to-day comfort. They’re virtually maintenance free, with an A energy rating as standard, and a wide range of colours and finishes to suit your home.

Typical 2026 cost: £400 to £950 per window, fully fitted, making casement the most affordable style and the benchmark most other window prices are compared against.

uPVC Sliding Sash Windows

Sliding sash windows replicate the classic vertical-sliding style of traditional timber sash windows, hugely popular for period properties in and around Knutsford, while delivering the thermal performance and low maintenance of modern uPVC. The REHAU Heritage system in particular has been developed with conservation bodies, making it one of the most authentic-looking uPVC sash windows on the market, with classic hardware, optional decorative horns and Georgian bar detailing to replicate a genuine timber sash.

If your property sits in a conservation area, sliding sash windows are often the preferred, and sometimes required, style to maintain the character of the street.

Typical 2026 cost: £700 to £1,500 per window, fully fitted, reflecting the more complex sliding mechanism and additional frame detail compared to casement.

uPVC Tilt and Turn Windows

Tilt and turn windows offer a simple, contemporary solution well suited to modern properties. A single handle gives you two opening options: tilt inward from the top for secure, draught-free ventilation, or turn fully inward like a door for easy cleaning and maximum airflow. This makes them a particularly practical choice for upstairs windows or anywhere that’s awkward to clean from outside.

Typical 2026 cost: £550 to £1,150 per window, fully fitted, typically 15 to 25% more than an equivalent casement window due to the more sophisticated hardware.

uPVC Flush Sash Windows

Flush sash windows offer a sleek, modern appearance, the sash sits flush with the outer frame rather than sitting proud of it, giving a cleaner, more contemporary look that still works well on both period and modern properties. It’s a popular middle-ground choice for homeowners who want a refined finish without going as far as a full sliding sash.

Typical 2026 cost: £500 to £1,050 per window, fully fitted.

Which Window Style Is Right for You?

• Casement suits most homes and budgets, and is the most versatile, affordable option
• Sliding sash suits period properties and conservation areas where authenticity matters
• Tilt and turn suits modern homes and hard-to-reach windows where easy cleaning matters
• Flush sash suits homeowners wanting a sleek, contemporary finish on any property style

What Does a Full House of Windows Cost?

For a typical three-bedroom semi with 8 to 10 windows, a full uPVC replacement in casement style typically costs between £4,000 and £9,000. Choosing sliding sash, tilt and turn or flush sash throughout will increase this, and most homes mix styles, casement for standard rooms, sliding sash for a period-style front elevation, for example. Every quote is free and based on your specific property, so you’ll know the exact cost before committing to anything.
