How quickly does it warm up?

Most of our heaters and warmers give noticeable heat within one to two minutes. Exact times are listed in the product description.

Is it safe to leave running?

Our heaters are designed with safety features such as overheat protection, and many also have tip-over protection — check the product description for the exact features. Never cover a heater and always follow the instructions.

Will it work with UK plugs and car sockets?

Mains products come with a UK-compatible plug or adapter. Car products use the standard 12V socket found in UK cars.

How much energy does it use?

Because you only heat the space or person you need, you often use far less energy than heating the whole house. The wattage is shown on every product page.

Your tree, your colours, your phone

These smart Christmas lights turn a 20 m, 200 LED string into a light show you control from your sofa. Pick any of 16 million colours or 170+ ready-made scenes in the free app, build your own DIY effects, set timers and daily schedules so the tree switches on by itself, and let the music-sync mode make the lights move to your playlist. They work with popular voice assistants for hands-free control and can be grouped with other compatible lights across rooms, porch and garden, with sharing so the whole family can join in. The lights run from the mains via the controller; selected variants are USB powered.
