What You'll Learn
Cost per hour of use
Electric blankets typically consume between 100 to 200 watts per hour, depending on the size and heat setting. To calculate the cost per hour, multiply the wattage by the number of hours used, then divide by 1000 to convert to kilowatt-hours (kWh). Finally, multiply by the average UK electricity rate, currently around 28p per kWh. For example, a 150-watt blanket used for 8 hours nightly costs approximately 33.6p per night (150 × 8 ÷ 1000 × 28). This straightforward calculation reveals electric blankets are an energy-efficient heating option, especially compared to central heating.
Consider this scenario: using an electric blanket for 8 hours nightly over a 30-day month totals roughly £10.08 (33.6p × 30). In contrast, heating an entire room with a 2kW radiator for the same duration could cost over £60 monthly. The key takeaway? Electric blankets offer targeted warmth at a fraction of the cost, making them a budget-friendly alternative for chilly nights.
To maximize savings, use the blanket on lower settings, as higher temperatures increase energy consumption. Preheat the bed 30 minutes before use, then turn it off once in bed—modern blankets retain heat effectively. Pair this with a timer or thermostat-controlled model to avoid unnecessary usage. These small adjustments can reduce costs further, ensuring you stay warm without overspending.
Comparatively, electric blankets outshine other heating methods in cost-efficiency. For instance, a hot water bottle uses no electricity once heated, but its warmth lasts only 2–3 hours. Electric throws or heated mattress toppers consume similar energy but may be less efficient if used incorrectly. Electric blankets, however, provide consistent, localized heat, making them the most cost-effective choice for prolonged use.
Finally, while the cost per hour is low, cumulative usage matters. If you use the blanket nightly for six winter months (180 days), the total cost rises to £18.14 (33.6p × 180). Still, this pales in comparison to central heating bills, which can exceed £500 for the same period. By understanding and managing usage, electric blankets remain an affordable, eco-friendly way to combat the cold.

Energy consumption comparison
Electric blankets typically consume between 100 to 200 watts of power, depending on the size and heat setting. To put this into perspective, running a 150-watt electric blanket for one hour costs approximately 2.1 pence, based on the UK’s average electricity rate of 14p per kWh as of 2023. Compare this to a 2kW oil-filled radiator, which costs around 28p per hour to run. This stark difference highlights how electric blankets can be a cost-effective alternative for staying warm, especially during colder months.
Consider the practical application: using an electric blanket for two hours nightly over a month (30 days) would cost roughly £1.26. In contrast, running a central heating system for the same duration could easily exceed £50, depending on your home’s insulation and thermostat settings. For those looking to reduce energy bills, preheating your bed with an electric blanket for 30 minutes before sleep, then turning it off, can provide warmth without continuous energy use.
However, energy consumption isn’t solely about cost—it’s also about efficiency. Electric blankets heat specific areas (your bed), whereas central heating warms entire rooms, often inefficiently. For instance, if you lower your thermostat by 1°C and use an electric blanket instead, you could save up to £80 annually on heating bills, according to Energy Saving Trust estimates. This targeted approach minimizes wasted energy, making electric blankets a smarter choice for individual comfort.
To maximize savings, pair your electric blanket with a timer or thermostat-controlled model. These features ensure the blanket doesn’t run unnecessarily, further reducing consumption. For example, a blanket with an auto-shutoff after one hour uses 70% less energy than one left on for eight hours. Additionally, opt for newer models with lower wattage ratings, as they’re designed for efficiency without compromising warmth.
In summary, electric blankets are a low-cost, energy-efficient solution for staying warm in the UK. By understanding their consumption patterns and using them strategically, households can significantly reduce heating expenses while maintaining comfort. Whether as a supplement to central heating or a standalone option, electric blankets offer a practical way to navigate rising energy costs.

Cheaper alternatives to electric blankets
Electric blankets can be a cozy solution for chilly nights, but their running costs often raise eyebrows. In the UK, where energy prices fluctuate, the expense of keeping one switched on can add up. Fortunately, there are budget-friendly alternatives that deliver warmth without the hefty electricity bill.
Layering Up: The Art of Insulation
Start with the simplest method: layering. Adding extra blankets, throws, or duvets with high tog ratings can trap body heat effectively. Opt for materials like fleece or wool, which retain warmth better than cotton. For instance, a 15-tog duvet paired with a fleece blanket can rival the warmth of an electric blanket. Pro tip: Place a hot water bottle at the foot of the bed 30 minutes before sleep to preheat the area, then remove it before settling in.
Microwavable Heat Packs: Portable Warmth
Microwavable heat packs filled with wheat or lavender are a reusable, energy-free option. Heat one for 1–2 minutes (follow manufacturer instructions) and tuck it under the covers. These packs retain heat for up to an hour, making them ideal for warming the bed before sleep. They’re also versatile—use them on sore muscles or as hand warmers during the day.
Thermal Bedding: Invest in Long-Term Comfort
Thermal bedding, such as flannel sheets or brushed cotton, can significantly improve warmth retention. Pair these with a thermal mattress topper or underblanket made from materials like sheepskin or synthetic fibers. While the initial cost may be higher, these items pay for themselves over time by reducing the need for additional heating. For example, a £30 thermal underblanket can last for years, whereas an electric blanket might cost £10–£20 annually to run.
Draft-Proofing: Seal Out the Cold
Cold air seeping into the bedroom can negate the warmth of any blanket. Draft-proofing your space is a cost-effective way to retain heat. Use draft excluders for doors, seal gaps around windows with insulation tape, and invest in thick curtains to keep cold air out. A well-insulated room means less effort (and expense) is needed to stay warm.
By combining these strategies, you can create a snug sleeping environment without relying on energy-intensive solutions. Each alternative offers unique benefits, from the immediate warmth of a hot water bottle to the long-term efficiency of thermal bedding. The key is to tailor your approach to your specific needs and budget.

Impact on monthly electricity bills
Electric blankets typically consume between 100 to 200 watts per hour, depending on the heat setting and model. To put this into perspective, running a 150-watt electric blanket for 8 hours nightly uses approximately 1.2 kWh per day. At the UK’s average electricity rate of 28p per kWh (as of 2023), this equates to roughly £3.36 per month. While this may seem modest, the cumulative cost depends on usage frequency and duration. For instance, using the blanket only on colder nights can significantly reduce monthly expenses compared to daily use.
Consider this scenario: a household uses a 150-watt electric blanket for 6 hours nightly, 5 nights a week. This totals 4.2 kWh weekly, or 18 kWh monthly, costing about £5.04. In contrast, preheating the bedroom with a 2,000-watt convection heater for 30 minutes nightly consumes 1 kWh daily, or 30 kWh monthly, costing £8.40. Here, the electric blanket emerges as a more cost-effective option for targeted warmth. However, pairing it with central heating or other appliances simultaneously can inflate overall energy bills.
To minimize costs, adopt strategic usage habits. Set the blanket to preheat the bed 30 minutes before use, then turn it off or switch to a lower setting once in bed. Modern electric blankets with timers or auto-shutoff features can automate this process, preventing unnecessary energy consumption. Additionally, ensure the blanket is properly fitted to the bed to retain heat efficiently. For households with multiple users, allocate blankets based on individual needs—for example, elderly family members or those with poor circulation may benefit more from prolonged use.
Comparatively, electric blankets are far cheaper to run than alternative heating methods. A 3,000-watt oil-filled radiator, used for 2 hours nightly, consumes 6 kWh daily, or 180 kWh monthly, costing a staggering £50.40. Even electric throw blankets, which average 60 watts, are more efficient for short-term use but lack the coverage of a full-sized blanket. For long-term savings, invest in a high-quality electric blanket with energy-efficient features, as cheaper models may have higher wattage or lack safety mechanisms, potentially increasing costs and risks.
In conclusion, electric blankets are not inherently expensive to use in the UK, but their impact on monthly bills hinges on usage patterns and complementary heating strategies. By optimizing settings, leveraging timers, and comparing them to costlier alternatives, households can enjoy warmth without significant financial strain. Always balance comfort with energy efficiency to maximize savings while staying cozy during colder months.
