London isn’t exactly known for its AC ;) but it can get warm! If you are visiting in a warmer climate, I’d recommend getting a tower fan. Full feature list below:

• HANDY TIMER: Your VonHaus tower fan features a 7-hour timer function so you can set and forget. Programme your fan to turn off and cool your bedroom or home office without wasting precious electricity.
• ADJUSTABLE SETTINGS: With 3 speed settings (low, medium, high) your electric fan keeps you cool anytime. A gentle breeze to help you sleep or a blast on a hot day – with 3 breeze speeds, your standing fan can cope.
• EASY TO USE: With a handy remote control, you don't even have to move to adjust your oscillating fan, and with an easy to read, illuminated display, staying cool is simplicity itself.
• COMPACT DESIGN: Measuring H87cm x W28cm x D28cm and housed in a sleek black casing, your fan fits neatly into tight spaces in any room. With RoHS, REACH and CE safety certification your fan is ready to go.
