Capacity

Kettle capacity is one of the most important factors to consider before buying. Standard kettles typically hold between 1 litre and 1.7 litres, making them ideal for families or those who regularly make multiple hot drinks at once. If you live alone or have limited worktop space, a compact or travel kettle with a smaller capacity could be the smarter choice.

Speed

Boil speed is a key consideration for many buyers, particularly during busy mornings or when entertaining guests. Most electric kettles operate between 2,200W and 3,000W, with higher wattage delivering faster boil times. If speed is a priority, look for a kettle with a higher wattage rating to get your hot drinks ready in no time.

Temperature control

For those who take their hot drinks seriously, a variable temperature kettle is well worth considering. Rather than boiling water to 100°C every time, these kettles allow you to select a precise temperature to suit different drinks. Green tea, for example, is best brewed at around 70°C to 80°C, while coffee typically requires water closer to 90°C to 96°C. A variable temperature kettle ensures every cup is brewed to perfection, preserving the full flavour of your favourite hot drinks.

Safety features

Safety is an important factor when choosing a kettle. Look for models with automatic shut-off to prevent dry boiling, cool-touch handles to reduce the risk of burns, and durable heat-resistant materials built to last. If you have young children or pets at home, it is also worth considering a kettle with a cool-touch exterior, as some models can remain hot to the touch for several minutes after boiling.

Design

A kettle sits on your worktop every day, so finding one that complements your kitchen style is well worth the effort. From sleek stainless steel designs to retro-inspired colourways, there is a kettle to suit every home aesthetic. For something truly eye-catching, some brands collaborate with well-known designers and lifestyle names, offering limited edition styles that make a real statement in the kitchen.

Noise level

Noise level is often an overlooked consideration when buying a kettle. If you are sensitive to sound, share your home with light sleepers, or frequently make hot drinks early in the morning or late at night, it is worth looking for a quieter model. Many modern kettles are designed with noise reduction in mind, allowing you to boil water quickly and discreetly without disturbing those around you.

Is a higher wattage kettle better?

Well, that depends. If you’re a chain tea drinker, then a high wattage (3 kWh) kettle might be better for you as it’ll boil the kettle faster, saving you time between cups. The faster boiling process also means the kettle is running for a shorter period, which can actually make it more energy-efficient in practice. While high-wattage kettles use more power per minute, they often end up consuming less total energy than a lower-wattage kettle that takes longer to reach boiling point. However, if you’re happy to wait a couple of minutes longer or you only use your kettle occasionally, a lower wattage kettle of 1-2 kWh might be all you need.

High wattage

With great wattage comes great boiling speeds. If you’re a multitasker with a busy schedule, a high-wattage (around 3 kWh) kettle might be best suited for you as they can take as little as 45 seconds to boil a cup of water. It’s a great way to get your water boiled faster, so you can continue to power through your to-do list.

Low wattage

If you work in a quiet environment, a lower wattage kettle might be better suited to you as it heats more gradually which means it’ll make less noise during boiling. The slower pace can also give you better temperature control, so it’s ideal if you enjoy brewing delicate teas or need specific water temperatures for different drinks. Lower wattage kettles also tend to be gentler on internal components which means they’ll potentially last you longer than a rapid boil kettle.

How much electricity does a kettle use?

If you’re just making a quick cup of tea for yourself (about 250-300ml of water), you’ll only use a small amount of electricity, around 0.03 - 0.05 kWh. Depending on the wattage of your kettle, this can take anywhere from 45 seconds to 1.5 minutes for the kettle to be fully boiled. However, if you’re brewing a pot for the whole family, say about 1.5 litres to make 5-8 cups of tea, it’ll take 0.17 - 0.26 kWh, and up to 6 minutes to get that water bubbling.

How many watts does a kettle use?

Typically, between 1-3kw, but every kettle is different. Some are made to boil water quicker, which means they use more watts and some are made with eco considerations in mind, so they use a little less. A full 3kW kettle can take between 2-4 minutes to boil whereas a full 1kW kettle can take 5-6 minutes so it’s important to choose a wattage that best fits your needs.

What is the average life of a kettle?

Many kettles last between 4-5 years with proper use, which is pretty impressive given how often we use them. They are a great investment that will pay dividends (and lots of hot brews) for years to come.

Which brand of kettle is right for me?

Electric kettles

The type most of us think of when we hear the word ‘kettle’. They have an internal heating element and are powered via plug socket. They boil water faster than stovetop kettles and often come with features like temperature control and automatic shut-off.

FAQs

Are more expensive kettles worth it?

If you’re after a kettle that’ll come with the latest technology and last you for years to come, then it’s often better to spend slightly more for to make your life that little bit easier. Think variable temperature settings for brewing delicate teas at just the right heat, quiet-boil technology for early mornings without waking the whole house, and fast-boil functionality to get your cuppa ready in seconds. Plus, many premium kettles come with energy-saving modes, keeping long-term costs down.

Are filter kettles worth it?

Filter kettles can be really beneficial, especially if you live in an area with hard water. They are designed to remove impurities like chlorine and limescale which can improve the taste of your water and the quality of your favourite hot drinks. However, many models require cleaning and filter changes to keep the kettle functioning at its best, but for a lot of people, the better-tasting water, health benefits and limescale protection is worth that little extra maintenance.

What are the most energy-efficient kettles?

Generally speaking, the most energy efficient kettles are low-wattage models or those with a rapid-boil function. However, at the very least it’s worth looking for a kettle that features precise cup-level indicators and variable temperature settings as these will help you heat only the exact amount of water you need for each boil.

What size kettle should I buy?

This really depends on how many people live in your household. For most homes, a kettle between 1.5 litres and 1.7 litres is a good option as it will make multiple brews with one filling without taking up too much counter space. If you live on your own or have an especially small kitchen, a 1 litre to 1.2 litre model should suit you perfectly. For larger households you might find a kettle of at least 2 litres will be ideal.

How do you descale a kettle?

You can easily descale your kettle by filling it to the halfway point with either an equal mix of water and distilled white vinegar, or water with two or three tablespoons of lemon juice. Boil the kettle, then allow it to stand for around half an hour. Empty the kettle and rinse thoroughly. It’s also recommended to fill the kettle and boil before pouring the water away, just to make sure any last traces of taste remain.
