In 2025, blackout curtains have become a key feature in UK homes. They block up to 99% of sunlight, reduce outside noise, and help lower energy bills. With thermal, smart, and eco-friendly designs now widely available, blackout curtains offer an easy way to make any room darker, quieter, and more comfortable.
In 2025, blackout curtains are one of the most practical home essentials in the UK. As more people focus on creating peaceful and energy-efficient living spaces, these curtains have become a preferred choice for bedrooms, nurseries, and even home offices. Made with layered or dense fabrics, blackout curtains effectively block out sunlight, reduce outside noise, and help regulate room temperature throughout the year.
In busy cities and towns where streetlights and noise pollution are common, blackout curtains are particularly valuable. They help people sleep better, maintain privacy, and save on heating and cooling costs. Modern versions also come with smart technology, eco-friendly materials, and designs that blend easily with contemporary interiors. This 2025 guide explains what blackout curtains are, their benefits, different types available, and how to select the best ones for your home in the UK.
What Are Blackout Curtains and What Do They Do?

Blackout curtains are specially designed window coverings that block most or all natural light from entering a room. Unlike ordinary curtains, they are made using thick, multi-layered fabrics such as triple-weave polyester, foam backing, or thermal lining. These materials can block between 95% and 99% of sunlight, making them ideal for improving sleep quality and comfort.
The dense fabric layers not only block light but also reduce sound from outside and help regulate indoor temperature. During cold months, they trap heat inside, and during summer, they prevent warm air from entering. As a result, they keep rooms comfortable all year while reducing energy consumption.
In 2025, blackout curtains have evolved beyond functionality. Many include added features such as eco-friendly recycled materials, flame-retardant coatings for safety, and smart control systems that allow users to open or close curtains using voice commands or mobile apps. They are also available in various styles—eyelet, pencil pleat, and tab top—so homeowners can easily match them with any room décor.

Why Blackout Curtains Are Popular in the UK in 2025

The popularity of blackout curtains continues to rise in the UK because of the comfort and energy efficiency they provide. There are several reasons why more households are choosing them today.
One of the biggest benefits is improved sleep. Complete darkness signals the body to produce melatonin, the hormone responsible for healthy sleep cycles. People who work night shifts or live in areas with bright streetlights find blackout curtains especially helpful for creating the right sleeping environment.
Another key reason is energy saving. With rising energy prices across the UK, blackout curtains act as a simple yet effective insulation barrier. Thermal-lined curtains keep warmth inside during winter and block heat during the summer months, reducing the need for heating or air conditioning. This can help lower electricity bills and make homes more energy efficient.
They also reduce outside noise, which is ideal for city residents who live near main roads, railways, or schools. In addition, blackout curtains protect furniture, flooring, and wall paint from fading by blocking harmful UV rays. Many homeowners in London, Manchester, Birmingham, and other major UK cities now use blackout curtains to combine practicality, privacy, and comfort in their living spaces.
Different Types of Blackout Curtains You Can Buy

There are several types of blackout curtains available in the UK in 2025, each with its own features. Thermal blackout curtains are the most popular and are best for keeping rooms warm in the winter and cool in the summer. Noise-reducing blackout curtains have extra layers that help block outside sounds, making them good for homes near busy roads or schools. Portable blackout curtains can be fixed using suction cups or Velcro and are great for people who rent or travel often. Smart blackout curtains can be controlled with your phone or voice and are useful in modern homes. Decorative blackout curtains come in prints and fancy fabrics like velvet, making them great for living rooms. Layered blackout curtains combine sheer and blackout fabric in one set, so you can let light in during the day and block it at night. Flame-retardant blackout curtains meet UK safety rules and are good for nurseries or kitchens. Eco-friendly blackout curtains are made from recycled fabric or organic cotton and are a great choice for green homes.
How to Choose the Right Blackout Curtains for Each Room

Choosing the right blackout curtains depends on the function of each room. Bedrooms usually need total darkness and thermal insulation, while living areas may require style and versatility.
In bedrooms, full blackout curtains with thermal lining are recommended to ensure complete darkness and warmth during cold nights. For nurseries, opt for flame-retardant and washable materials without cords for child safety. Living rooms can benefit from decorative blackout curtains made of velvet or patterned fabric that blend with the furniture and still provide light control.
Home offices require sound-reducing curtains to maintain concentration and reduce background noise. In kitchens, lightweight, flame-resistant options are practical and safe. Portable blackout curtains are ideal for renters who cannot drill holes or want a temporary solution. Always measure carefully before purchasing—curtains should extend 15 to 20 centimetres beyond the window frame on both sides and reach the floor to prevent light from leaking through the edges.

Installing and Maintaining Blackout Curtains

Installing blackout curtains is simple but requires accurate measurements. Curtains should always be wider and longer than the window to ensure full coverage. Use a sturdy curtain rod that can support heavy fabrics, especially for thermal and velvet types. When hanging, make sure the curtains overlap the edges of the window to stop light leaks.
For smart blackout curtains, follow the manufacturer’s setup instructions to connect them to your smart home devices. To keep your curtains clean, vacuum them once a month using a soft brush attachment. Many blackout curtains can be machine-washed on gentle cycles, but some—especially those with foam backing or velvet fabrics—should be dry-cleaned. To remove wrinkles, use a handheld steamer or a warm iron on a low setting. Proper maintenance helps preserve the curtains’ colour, texture, and insulation for several years.
