Which to Pick By [SM Windows & Doors](https://smwindowsanddoors.co.uk/blog/author/sm-windows-doors) Sep 28, 2026, 3:30:00 PM 3 Minutes Read Casement windows are the most common style on British homes, but there is a choice within them that trips people up: the flush casement or the standard one. If you are weighing up flush vs standard casement windows for a York home, this guide explains the difference, how each looks and costs, and which tends to suit older and newer properties. ## What is the difference? Both are casements, meaning they open on hinges at the side (or sometimes the top) like a door. The difference is how the opening sash sits against the frame when closed. - **Standard (lipped) casement:** the opening sash sits slightly proud of the frame, with a small lip that overlaps the outer frame. This is the everyday casement you see on most modern homes. - **Flush casement:** the sash closes flush into the frame, sitting neatly level with it, so the whole window presents a flat, even face. This mimics the look of traditional timber casements. It sounds like a small detail, and mechanically it is, but it makes a real visual difference, especially on a period property. ## The look This is the heart of the decision. - A **flush casement** has clean, flat lines and that softer, traditional appearance. It is the closer match to the old timber windows found on Victorian, Edwardian and cottage-style homes, so it tends to look right on York's older streets. - A **standard casement** has the slightly stepped, layered profile of a typical modern window. It looks perfectly smart on newer homes, estates and new-builds, where a period look is not the aim. If keeping the character of an older home is important to you, the flush look usually wins hands down. On a modern house, either works and many people happily choose standard. ## Cost As you would expect, the more traditional option carries a small premium. As a rough 2026 guide, supplied and fitted: - **Standard casement:** roughly 400 to 900 pounds per window. - **Flush casement:** often around 10 to 20 percent more, so roughly 450 to 1,050 pounds per window. The gap is not huge per window, but across a whole house it adds up, so it is worth deciding whether the flush look matters enough to you. Prices vary with size, material and glazing, so get a quote for your own windows before you commit. ## Performance On the numbers, there is very little between them. Both flush and standard casements are available in efficient double or triple glazing, both seal well against draughts, and both are secure with modern multipoint locking. So this is genuinely a decision about looks and budget, not one about warmth or security. Choose the style you prefer and you will not be trading away performance either way. ## Which suits older York homes? For period terraces, cottages and older houses, and especially anything in a conservation area, the flush casement is usually the better fit because it echoes the original timber windows. It keeps the frontage looking honest to its age. A quick word on conservation areas: if your home is in one, or is listed, the council may have views on window style, material and sometimes colour. A flush casement is often more sympathetic, but rules change and vary, so check the current requirements with the City of York Council or your local authority before ordering. ## Which suits newer homes? On modern houses, new-builds and estates around the ring road, a standard casement looks completely at home and keeps the cost down. There is no character being lost, so the practical, everyday choice makes sense. That said, some people fit flush casements on modern homes simply because they like the cleaner, flatter look, and that is a perfectly good reason too. ## Our steer If you have an older or period home, or you just love the traditional flat-faced look, go flush. If you have a modern home and want good value without fussing over period detail, standard is the sensible pick. Both come in our [casement windows](https://smwindowsanddoors.co.uk/casement-windows-york) range, and across our wider [uPVC windows](https://smwindowsanddoors.co.uk/upvc-windows-york) options in a choice of colours and finishes. If you are unsure what will suit your street, we are happy to take a look. ## FAQs ### What is the difference between flush and standard casement windows? On a standard casement the opening sash sits slightly proud of the frame with a small overlapping lip. On a flush casement the sash closes level with the frame for a flat, even face. The flush style more closely resembles traditional timber windows. ### Are flush casement windows more expensive? Usually a little. As a rough guide, flush casements often cost around 10 to 20 percent more than standard ones, reflecting their more traditional look. The gap per window is modest but adds up across a house. Prices vary with size and spec, so get a quote. ### Which is better for a period home, flush or standard? Flush casements generally suit period and older homes best, because their flat face echoes the original timber windows and keeps the character of the property. This is especially worth considering in conservation areas, where a sympathetic style may be expected. ### Do flush and standard casements perform differently? Not really. Both come in efficient double or triple glazing, both seal well against draughts, and both are secure with modern multipoint locking. The choice is about appearance and budget rather than warmth, security or energy performance. Want to see the full range of styles and finishes?
