Are electric fireplaces safe?
Yes, electric fireplaces are considered one of the safest ways to add warmth and ambience to your home, especially if you’ve got small children or pets. Unlike gas or wood-burning fires, they don’t produce real flames, carbon monoxide or smoke, which means no risk of burns, fumes or stray sparks.
Most models are designed with safety features built in, including overheat protection, automatic shut-off sensors and cool-touch glass fronts. This means even if curious little hands get too close, they won’t come into contact with anything dangerously hot. Many also have timers and thermostats, so they’ll switch off automatically when the room reaches your chosen temperature.
For the safest setup, plug your electric fireplace directly into a wall socket rather than an extension lead, and make sure there’s enough space around it for air circulation.
How much does an electric fireplace cost to run?
Running costs depend on your model’s wattage and your electricity tariff, but it’s easy to estimate how much it’ll cost you. Most electric fireplaces range between 1kW and 2kW, meaning that if your electricity rate is 30p per kWh (the current UK average), running it at full power will cost between 30p and 60p per hour.
If you only use the flame effect (with no heat), the running cost drops dramatically to typically just 1–2p per hour because it’s only powering the LED lights and display. This is why many people leave their electric fireplaces on for ambience, even when they don’t need the extra warmth.
Do electric fireplaces heat up a room?
Yes, electric fireplaces are designed to provide real, usable heat as well as cosy ambience, and they’re surprisingly effective for small to medium-sized rooms. Most models include a built-in fan heater that works a bit like a small convection heater: it pulls in cool air, passes it over a heated coil or element, and then gently blows the warmed air back out into the room. This creates a steady, even warmth that’s ideal for spaces such as living rooms, bedrooms or family snugs.
Typical electric fireplaces produce between 1kW and 2kW of heat, which can comfortably warm a room of around 15 to 25 square metres (roughly the size of an average lounge). Higher-end models often include thermostatic controls, letting you set and maintain your ideal temperature automatically. Some also come with timer functions so you can schedule them to turn on before you get home or switch off after bedtime.
Another advantage is that the heat is instant. Unlike log or gas fires, you don’t have to wait for it to build up. Just press a button and you’ll feel it within seconds. Because they’re electric, the heat they produce is 100% efficient at point of use (nothing is lost up a chimney), meaning every bit of energy goes straight into warming your room.
What’s the best electric fireplace to buy?
To find the best electric fireplace for your needs, you need to consider your space, budget and style. For realism and quality, Mumsnetters love the Dimplex Gosford Optimyst, which uses water vapour to create lifelike “smoke.” If you want something budget-friendly and modern, the Dimplex Dakota is a great all-rounder. If you prefer a freestanding design, the Focal Point Fires Horsham Suite gives you instant fireplace vibes with no installation required.
How we choose our electric fireplace recommendations
Recommendations from real Mumsnet users
When it comes to choosing the best electric fireplaces, we know parents want more than polished marketing claims. It’s much more useful to have real, honest feedback from families who’ve actually used them. That’s why every model in this guide has been vetted, assessed and evaluated to see if it truly deserves its spot.
We started with the Mumsnet forums, scouring through threads to reveal which electric fireplaces are tried, tested and trusted in real homes. From there, we analysed, compared, and weighed up key factors such as heat output, safety, energy efficiency, and ease of installation. Only products that stood up to in-depth scrutiny and extensive research made the final list.
Expert opinions and in-depth research
Next, we turned to expert insight to ensure every recommendation was thoroughly evaluated and independently verified. Alongside the honest experiences of Mumsnetters, we researched and investigated reviews from trusted UK sources such as Which? And the Good Housekeeping Institute. These publications regularly test and scrutinise home appliances for safety, efficiency and ease of use, giving us valuable data to compare.
With electrical appliances, safety is a big concern. As part of our research, we checked that each model met BSI standards for electrical safety and carried BEAB certification, to make sure they’d been independently tested and approved for safe use.
Verified customer reviews
To be confident that our recommendations reflect real-life, we researched and analysed verified customer reviews from trusted retailers including Amazon, Robert Dyas, B&Q and other major stores. We looked at hundreds of genuine buyer comments to evaluate how these electric fireplaces perform day-to-day in people’s homes.
We paid particular attention to what reviewers said about heat output, noise levels, flame realism, ease of setup, running costs, and durability. Fires with consistently high ratings for quality, reliability and safety were weighed up and considered more favourably. At the same time, we scrutinised repeated complaints, such as issues with fan noise, build quality or customer service, to make sure our list only contains models that are genuinely trusted and recommended by real users
