Are electric blankets more cost effective than central heating?

Key takeaways

• With the Energy Price Cap at around 24.5p per kWh, a 100W electric blanket costs about 2.5p per hour to run making it a cost-effective way to stay warm

• Electric heaters like fan heaters, use around 2kW per hour, costing about 49p per hour to run

  Central heating, using gas at around 5.7p per kWh, costs around £1.35 per hour or £162 per month if used for four hours daily

• Electric blankets can save money compared to central heating, but they only warm the person not the room, which can lead to issues like mould

Are electric blankets a good investment?

As the chill of winter sets in, the quest for cost-effective warmth becomes a priority for many households. Among the myriad of options, electric blankets stand out as a cozy solution.

Available as underblankets for beds and throws for sofas, these heated comforts come with a range of prices, starting from £30 and climbing over £100 for underblankets, while throws begin at £50. But beyond the initial purchase, what does it really cost to snuggle up under an electric blanket?

How much do electric blankets cost to use?

When it comes to operating costs, the energy price cap has set electricity prices at around 24.5p per kWh. This means that a 100W electric blanket, which uses 0.1kWh, will cost you a mere 2.5p per hour.

If you're using the blanket for a typical two-hour wind-down at bedtime, you're looking at around 5p per day, a small price to pay for the comfort it provides.

Opting for cooler settings on your electric blanket can further reduce costs, making it a particularly economical choice for heating individuals directly, rather than entire unused rooms.

Comparing electric heaters and central heating

When weighing up the costs of electric blankets against other heating methods, it's important to consider the alternatives. Electric heaters, for instance, can be quite the energy guzzlers.

A fan heater, which typically uses around 2kW per hour, will cost about 49p per hour to run under the current UK price cap. It's always a good idea to check for deals below the Energy Price Cap to find more precise running costs.

On the other hand, gas prices have seen a decrease from their peak in 2022, with the Energy Price Cap setting them at around 5.7p per kWh for April to June 2026.

While energy providers may offer deals below this cap, the costs can still add up. A boiler, for example, uses about 24kW per hour, translating to roughly £1.35 per hour.

If you're running your heating for four hours a day, that's close to £162 per month. To save on these costs, consider lowering your boiler temperature and turning off radiators in rooms that aren't in use.

Smart energy use and savings

The Energy Saving Trust recommends only turning on your heating when you need it. You can save money by installing insulation in your loft or walls and draft-proofing doors and windows.

In areas prone to condensation, it may be wiser to keep the heating on low continuously rather than cycling it on and off, which can exacerbate condensation issues.

Investing in a smart meter can also lead to savings, as it allows you to control the heating in different areas of your home right from your smartphone.

Can an electric blanket replace my central heating?

Electric blankets may offer significant savings since they are used only when needed and generally cost less than running central heating.

However, it's important to note that they are not a direct replacement for central heating systems, which warm entire rooms or homes, as opposed to blankets that warm individuals or beds.

Do electric blankets cause mould or damp?

One aspect to be mindful of is that electric blankets do not warm the room air, which can lead to potential health issues and promote the growth of mould and damp.

It's crucial to balance the use of electric blankets with adequate room heating to maintain a healthy living environment.

What support can I get for heating costs in the winter?

For those struggling with heating costs in winter, it's worth remembering that there are government schemes available, including the Warm Home Discount, the Winter Fuel Payment, and the Cold Weather Payment.

These programs can provide much-needed financial relief during the colder months.
