How Much Electricity Do Christmas Lights Use UK?

When it comes to the cost of Christmas lights, there are two major aspects to consider.

To begin, purchase and set up the display, and then pay to have them operate for several hours a day, at least for the month of December.

LED lights are thought to produce energy savings of up to 90% when compared to traditional incandescent bulbs, making them the more energy-efficient and ecologically friendly option.

This is because the latter contains a filament, which wastes around 90% of the energy it produces as heat.

According to Which?, the cost of electricity for a typical family running seven strings of 100 incandescent lights for six hours every day until December would be $8.94 ($11.55).

Meanwhile, LED lighting would bring the price down to roughly 90p ($1.16), according to the report.

Do Christmas tree lights in the United Kingdom consume a lot of electricity?

Christmas wouldn’t be complete without lights, but have you ever considered how much you’re spending?

With electricity prices on the rise, many families are debating whether or not to decorate their halls this year, fearing a nasty surprise when the bill arrives.

Of course, the length of time you keep your lights on each night and the number of lights you use will have an impact on your final costs.

However, depending on the usual quantity of holiday bling, your bill is unlikely to be excessive.

According to Which?, the average cost of turning on your Christmas lights for a month is only 8.94 pounds, and if you use LED bulbs instead of incandescent bulbs, your monthly charge can be as low as 90 pence.

This figure is based on turning on your lights for at least six hours a day for a month.

It is, however, based on seven strings of 40 watt lights, each with 100 lights.

That should be enough to adorn a tree, a few windows, or a fireplace.

If you go all out with full-on exterior lights and leave them on for longer, your bill could skyrocket.


Is it true that Christmas lights consume a lot of electricity?

A string of 25 C9 bulbs (the big plump ones commonly used outside) uses 175 watts of electricity, which calculates out to a whopping $15.12 every season (assuming 12-hour-a-day operation for 45 days).

How much does it cost to keep Christmas tree lights on in the United Kingdom?

The cost of lighting your Christmas tree has been assessed by Crown Pavilions. The majority of us use two strings of lights, totaling 80 watts of energy.

If your lights are left on for 6 hours a day, 0.08kW multiplied by 6 hours equals 0.48kW. With energy prices around 17p per kW, keeping your lights on for 6 hours a day for a month will only cost you 2.48.

How much does it cost to run Christmas lights?

Now comes the equivalences. Based on whether the bulbs are LED or incandescent, three different forms of light strandsmini, C9, and C7 are compared below. Each cost was calculated based on six hours of usage per day over 30 days for these comparisons.

A strand of 300 white micro LED lights on standard green wire consumes 21 watts, but an incandescent bulb strand consumes 72 watts. Using the math above, a strand of tiny LED lights will cost you roughly 52 cents if you use the national average of $0.14 per kilowatt-hour and a display season of six hours per day for 30 days. A strand of the same number of bulbs, but incandescents, will set you back $1.81.

What in a house consumes the most electricity?

The breakdown of energy use in a typical home is depicted in today’s infographic from Connect4Climate.

It displays the average annual cost of various appliances as well as the appliances that consume the most energy over the course of the year.

Modern convenience comes at a cost, and keeping all those air conditioners, freezers, chargers, and water heaters running is the third-largest energy demand in the US.

Here are the things in your house that consume the most energy:

  • Cooling and heating account for 47% of total energy consumption.
  • Water heater consumes 14% of total energy.
  • 13 percent of energy is used by the washer and dryer.
  • Lighting accounts for 12% of total energy use.
  • Refrigerator: 4% of total energy consumption
  • Electric oven: 34% energy consumption
  • TV, DVD, and cable box: 3% of total energy consumption
  • Dishwasher: 2% of total energy consumption
  • Computer: 1% of total energy consumption

One of the simplest ways to save energy and money is to eliminate waste. Turn off “vampire electronics,” or devices that continue to draw power even when switched off. DVRs, laptop computers, printers, DVD players, central heating furnaces, routers and modems, phones, gaming consoles, televisions, and microwaves are all examples.

A penny saved is a cent earned, and being more energy efficient is excellent for your wallet and the environment, as Warren Buffett would undoubtedly agree.

How much does it cost to leave a light on all day?

Assume you have a 60-watt incandescent lightbulb and your energy bill is 12 cents per kWh. Leaving the bulb on for the entire day will cost you 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents = around 20 cents in a single day.

Do you waste more electricity by turning on and off the lights?

Contrary to popular belief, turning your lights on and off consumes no more energy than leaving them on.

One of the simplest methods to save electricity is to turn off the lights when you leave a room. Turning off the lights isn’t the only option to conserve energy on your home’s lighting, but it’s a great place to start.

How Turning the Lights On and Off Can Affect the Bulb

While turning the lights on and off has no effect on how much energy you consume, pushing the light switch quickly can shorten the life of any type of bulb.


Incandescent bulbs do not have a lifespan that is affected by turning them on and off. However, you’ve probably heard of incandescent bulbs’ inefficiency. Ninety percent of the energy used by an incandescent bulb is used to produce heat, with the remaining ten percent being used to produce light. A huge percentage of consumers are switching to LEDs and CFL bulbs for greater sustainability and energy efficiency.

Is it true that LED Christmas tree lights consume a lot of power?

The calculations are based on LED lights that utilize 0.1W per bulb, thus a 200-bulb display would use 20W.

“From December 9 to January 4, running a string of 200 LED fairy lights for six hours a night will cost you only 61 pence.

“Yet one out of every ten of us still uses halogen or incandescent bulbs for our holiday displays, which are much more expensive to run.

“If you want to cut your Christmas energy cost this year, try replacing any old, inefficient lighting with LED lights.

If you’re cold, we’ve calculated how much it costs to run an electric heater when the temperature drops.

What does it cost to run a light bulb for an hour in the United Kingdom?

Consider the following scenario:

If you pay conventional energy pricing, you may pay around 19 pence per kilowatt-hour. Alternatively, you could be paying around 15.50 pence per KWH if you’re on one of the cheaper online plans.

As a result, I’m going to state the obvious now.

On a typical plan, a 100 watt bulb would cost around 19 pence for 10 hours of use, or 1.9 pence per hour.

Alternatively, you might pay roughly 15.50 pence for 10 hours online, or 1.55 pence per hour.

Many people believe that a light bulb uses very little electricity. However, if you count the number of lights that are kept on unnecessarily and know how much energy each bulb uses, you can quickly discover how much money you are wasting by leaving these lights on.

The costs I’ve used in this example are practically exact, though I’ve rounded the figures to make the calculations easier.

The majority of energy providers, including:

  • Hydroelectric Power in Scotland
  • Southern Electric is a company that produces electricity.

Is it true that LED Christmas lights use less energy?

However, because of the electricity bill, LEDs will save you money in the long term. According to the US Department of Energy, they use 80 percent less energy than incandescent lights and last 25 times longer.

“Light strings are subject to weather,” Gardner continues, “so there’s no guarantee that LED lights will live longer.” If a squirrel eats a string of LED lights, they will fail just as quickly as glass lights.
