With December just days away, many households will be wondering how much it will cost to run Christmas tree lights this year.

Energy-efficient LED Christmas tree lights can keep costs lower over the holidays, using around 75% less energy than conventional bulbs to produce similar brightness levels.

Saxo, an investment platform, looked at how much it will cost to run Christmas tree lights based on the tradition of putting up decorations at the beginning of Advent (Sunday 3rd December), and keeping them up until Friday 5th January (Twelfth Night).

Based on the October 2023 energy price cap, which is 27.35p kWh, turning on these lights would cost you around 13p a day, or £3.99 a month if you kept them on for six hours a day. Plus, two 100-count strings of fairy lights running at 40 watts would total 80 watts, meaning a 0.48kW output will cost around £3.99 across the month. The more lights you have, the greater the cost.

Christmas tree lights create a wonderful glow, but make sure you turn them off once you leave the room. Having your Christmas tree lights on for more than six hours a day will impact the cost significantly, so it's advised to turn them off when you leave the house and before you go to bed.

Other ways to cut costs over the festivities include opting for fewer lights and considering the use of modern LED bulbs (incandescent light bulbs are often found on old Christmas lights and use far more electricity). Traditional Christmas candles are also a wonderful way to set the mood without bumping up your electricity bill.
