The cost of bay window shutters can vary significantly, but understanding the main factors will help you set a realistic budget and avoid surprises. The most important element influencing price is the size of your bay window, since shutters are typically priced per square metre. For a standard box bay window measuring about 2 square metres, prices for DIY shutters start from just over £400, while larger or more complex bays will cost more. If you opt for professional measurement and installation, expect to add up to 40% to the base price, bringing the cost for a similar window to around £600 or more.
Material choice also plays a big role. Entry-level options like MDF or craftwood are more affordable, while premium hardwoods such as basswood or mahogany increase the price. Composite and faux wood shutters offer a balance between cost and durability. For example, basic wood shutters start at about £175 per square metre, but high-end hardwoods can reach £300 per square metre or more.
The complexity of bay windows—with their angles and need for custom fitting—means installation is often more involved than with flat windows. This can further increase costs, especially if you require bespoke solutions or hidden hardware. Additional features, such as upgraded hinges or silent tilt rods, may add 10-15% to the total price.
To budget effectively, measure your bay window’s width and height to calculate the area, then multiply by the cost per square metre for your chosen material and service level. Don’t forget to factor in installation fees if you’re not going the DIY route. While shutters for bay windows represent a higher upfront investment than standard window treatments, their durability, energy efficiency, and timeless style often justify the cost for many homeowners
