How much does it cost to run your Christmas lights? Our finance expert has done the sums
If you’re curious to know how much does it cost to run Christmas lights, we’ve crunched the numbers to find out
With Christmas only a matter of weeks away, you might be wondering how much does it cost to run Christmas lights? It’s an important question to ask considering energy bills remain at record highs.
Even though the government’s Energy Price Guarantee is now in effect and households have started to receive a £400 energy rebate, families remain concerned about how much their energy bills will cost.
As a result, a sixth (16%) of UK households won’t be putting up their Christmas lights this year, while just over a quarter will be putting up fewer lights in a bid to save on energy costs, research from Go.Compare shows.
Go.Compare’s energy expert, Gareth Kloet, told us: “It’s not surprising that more people will be reconsidering putting up their Christmas lights this year, and completely understandable. With still no real end in sight to the energy crisis and the cost-of-living increases, people will undoubtedly be looking to cut back on some of the festivities this Christmas.”
How much does it cost to run Christmas lights?
It costs 0.12p an hour to run a typical 3.5W set of LED Christmas lights, with approximately 200 bulbs. If you switched your lights on for six hours a day, that would cost you 0.71p a day, 5p per week or 21.7p per month.
However, exact running costs will depend on the type of lights you have (LEDs will be much cheaper than traditional incandescent bulbs), how frequently you use them and how much you pay for your energy. For our calculations, we’ve used the Energy Price Guarantee’s electricity unit price of 34p per kWh.
Les Roberts, content manager at energy comparison site Bionic, says: “The running cost of Christmas lights can be worked out once you know the wattage and how much your electricity costs per KW. Your Christmas lights should have their wattage on the label, in the instructions or on the box. Once you have the wattage, divide the number by 1,000 to find how much energy the lights will use in the hour (known as the kilowatt hours or Kwh). Once you have calculated the kilowatt-hours and know your energy rate you can work out how much your lights cost in a time scale.”

How to cut the cost of running Christmas lights
Data from Festive Lights shows that demand for energy-saving lights has increased by 85% in the last month as families look for ways to enjoy the festive season for less. In light of this (no pun intended), here are some tips to help you cut the cost of running your Christmas illuminations:
Switch to LEDs
If you’ve got some traditional incandescent lights tucked away in the loft, it’s worth swapping them for some new LED lights instead.
Gardening expert at Hayes Garden World, Angela Slater, says: “LEDs are 5 to 10 times more economical than the traditional filament lights that we all used to run; this is because they use a lot less power to achieve the same light. As a bonus they are low voltage which is safer and they are cold to the touch, so essential if you have small children in the house. Other benefits are that the bulbs are practically unbreakable and they last an average of 10,000 hours.”
Reduce the number of lights
Another easy way to save some cash is to cut back on the number of lights you have around the home.
Energy expert at Housetastic.co.uk, Paul Newman, told us: “Try to stick to just a couple of strings, and position them somewhere you will see the most benefits, as buying a surplus of lights can really push up energy bill costs.”
Use a timer
Many modern versions of Christmas lights come with their own timer which makes it easy to keep them on for a limited time. If your lights do not have a timer, consider purchasing a smart plug to use alongside them.
“Smart plugs can be controlled using an app on your phone, allowing you to set a timer for lights to be switched off. This ensures that lights are not left switched on for an extended period of time,” explains energy expert Paul Newman.
Alternatively, PropertyRescue’s Callum Woodstock says: “Set alarms on your phone to remind you to turn off the lights before bed and ensure that you only have your lights on between twilight and bedtime.”
Switch to battery-powered or solar lights
Another option is to use battery-powered lights rather than electric lights. William Hobbs from trades matching site Myjobquote.co.uk says: “Although you’ll have to purchase batteries to power them, this won’t cost as much as electricity and battery lights tend to last a while before the batteries need to be replaced. To save even further money, consider purchasing rechargeable batteries.”
For outdoor lights, it can be worth using solar powered lights as these are powered by the sun and won’t cost you anything to run.
What features should you look for when buying Christmas lights?
When buying Christmas lights it’s important to do your research. As well as looking for lights that are more energy-efficient, look for ones that include a timer for six to eight hours a day.
Angela Slater from Hayes Garden World says: “Make sure you purchase from a reputable supplier and that there is an energy label on the packaging as there are cheap imports available which are not guaranteed to be safe and the LEDs are in fact cheaper lookalikes. Make sure you are buying exactly what you need and that the lights are fit for purpose. If lights are not labelled as being suitable for outdoors, don’t use them outside as they could short out and fuse the lights.”
If you are searching for lights for your Christmas tree, it’s important to choose the right cable length. Michael Meiser from lighting specialist Lumilum, says: “The general rule is 15 metres for a six-foot tree and five metres above or below for a foot higher or lower. But don't just look at cable length, as bulb size and spacing can vary. Another way to look at it is 100 lights per foot and a half of the tree, or double that number if you want your tree to really sparkle. The main thing is not to overload your tree with too many lights or cables, as these can get tangled or cause a fire in severe cases.”
