10 Best Alarm Clocks 2025 in the UK

This alarm clock combines a gentle wake-up experience with practical features. Its standout is the sunrise/sunset simulation light that gradually brightens and dims to help you wake up and fall asleep more naturally, which many users find more comfortable than traditional alarms. It supports dual alarms, making it ideal for couples or anyone needing different wake times on weekdays and weekends. The display is simple and clear, while the snooze function allows up to five extra 9-minute naps, giving flexibility without confusion.

It’s powered by a corded electric source, so no need to worry about batteries, and includes a handy USB port to charge your phone overnight. Additional perks include an FM radio with up to 60 saved stations and seven natural sounds to choose from, providing variety beyond the usual beep. The 7-color LED light option can also serve as a bedside or reading lamp.

On the downside, it has an energy class G rating, meaning it’s not very energy-efficient, and its plastic build might feel less premium. Also, the radio reception depends on adjusting the wires, which could be inconvenient. This wake-up light alarm clock suits those looking for a gentle, customizable waking routine with extra features like phone charging and radio, but who aren't concerned about energy use or a high-end finish.

The Lumie Bodyclock Glow 150 is an excellent choice for those looking to enhance their morning and bedtime routines with light therapy. As a wake-up light alarm clock, it simulates a gradual sunrise to help you wake up feeling more refreshed, which can be particularly beneficial for those who struggle with traditional alarm clocks. You can customize the sunrise duration and final light intensity, and choose from 10 different wake-up sounds to suit your personal preferences. The inclusion of a tap-control snooze function adds convenience for those who like a few extra minutes of sleep.

At bedtime, the fading sunset feature helps you unwind, with options to set the sunset duration and a choice of sleep sounds, including calming white noise. The clock's design uses mixed LEDs to mimic real sunrise and sunset colors and includes a light-sensitive auto-dimming display, which is a thoughtful addition for nighttime use to prevent disturbance.

As a certified medical device, it's also noted for its potential to alleviate symptoms of SAD (Seasonal Affective Disorder) and winter blues, making it a valuable tool for those affected by these conditions. Weighing just 0.57 kilograms and with compact dimensions, it fits well on a bedside table without taking up too much space. However, the Lumie Bodyclock requires mains power, so it isn't portable, and some users might find the plastic base and matte finish less appealing than more premium materials. While it boasts a high customer satisfaction rating, it is important to note the need for careful handling to avoid damage, especially since the unit can get warm when the light is on. Despite these minor drawbacks, its innovative features and health benefits make it a standout product in the wake-up alarm clock category.

The clock also offers a sunset simulation that gradually dims the light over 30 minutes, promoting relaxation and easier sleep onset, which can be particularly beneficial for children. The light-sensitive auto-dimming display ensures that the clock doesn’t interfere with sleep during the night. Additional highlights include its ability to aid in treating seasonal affective disorder (SAD), making it a valuable device during winter months. As a certified Medical Device, it provides reassurance of its therapeutic benefits.
