It’s completely fair to think about the numbers when it comes to electric heating. There’s the initial purchase price, of course, but what about the day-to-day running costs?
More homeowners are asking exactly that, especially as bathrooms become more intentional and design-led, rather than purely practical rooms. Comfort now matters just as much as function, and heating plays a bigger role in that than you might expect.
Why choose an electric towel rail
Electric towel rails are increasingly seen as a flexible, modern solution. They offer heat exactly where you need it, without relying on your entire central heating system. Instead of warming the whole house just to take the chill off one room, you can heat your bathroom on demand.
And because electric towel rails operate independently, they give you greater control over when and how you heat your space, which can make a real difference when it comes to managing energy use.
In other words, they're no longer just a luxury add on. In many homes, they're becoming a smart and considered choice.
So are electric towel rails expensive to run?
In many cases, not at all. Used thoughtfully, they can be an efficient way to heat a bathroom without firing up the boiler, especially in spring, summer or guest bathrooms that don’t need constant heating.
How much does an electric towel rail cost to run?
This all depends on the wattage of your towel rail and how long you use it.
Most electric towel rails range between 100W and 600W, with many bathroom-friendly models sitting around 200W–400W.
For example:
- A 300W electric towel rail running for one hour uses 0.3 kWh of electricity.
- At around 25p per kWh, that’s roughly 7.5p per hour.
If you used it for two hours a day, that’s around 15p per day to warm your bathroom and towels - or roughly £4.50 a month. In other words, it's costing less than a fiver a month for those toasty towels at the start of the day.
Of course, exact costs depend on energy tariffs and the size of your towel rail. But what makes electric towel rails appealing is control. You’re heating one room, for a set amount of time, rather than warming the whole house.
Many modern models also include:
- Timers
- Adjustable thermostats
- Smart Wi-Fi scheduling
- Frost protection settings
All of which help you manage usage and improve efficiency.
How does that compare to central heating?
Switching on your central heating to warm just the bathroom is a very different equation.
When the boiler fires up, you’re typically heating multiple radiators throughout the house at the same time, even rooms you’re not using. Depending on your boiler size and home setup, running central heating can cost significantly more per hour overall than running a single 300W electric towel rail.
Gas is generally cheaper per kWh than electricity in the UK. However, central heating systems rarely heat just one room in isolation. So while the cost per unit of gas may be lower, the total energy being used across the house is much higher.
An electric towel rail gives you targeted heat. It’s on when you need it, off when you don’t - which can make it a practical option for spring and summer use, guest bathrooms or when bathrooms are used at different times of the day in the same house.
Instead of heating the whole house for one room, you’re heating just the space you’re in.
What about dual fuel towel rails?
If you’re weighing up options, dual fuel towel rails sit neatly in the middle.
A dual fuel model connects to your central heating system but also includes an electric element. That means: In winter, it runs off your central heating system (powered by gas) and then in the warmer months, you can use the electric element independently.
This flexibility makes dual fuel towel rails a popular choice in modern homes. You get the efficiency of gas heating when the boiler is already on, and the control of electric heating when it isn’t.
So if you want year-round warmth without committing fully to electric, dual fuel can offer the best of both worlds.

So, do you need an electric towel rail?
Choosing between an electric towel rail, a dual fuel model or a traditional central heating radiator really comes down to understanding how you use your space.
If you want heat on demand, lower reliance on your boiler and more control over bathroom heating costs, an electric towel rail can be a practical and energy-conscious choice. If you prefer the flexibility of gas in winter and electric in warmer months, dual fuel offers that balance.
When used thoughtfully, the cost to run an electric towel rail is often lower than people expect, especially compared to heating an entire home just to warm one room.
So, smart upgrade or luxury extra? For many modern homes, it’s definitely becoming less of a luxury and more of a smart, everyday upgrade.
