On paper, most kettles look the same: 1.5 to 1.7 litres, a 3 kW element, a switch on the handle. The differences that matter in daily use are elsewhere: where the controls are, whether you can choose a temperature, how easy the water window is to read, how long it keeps water warm and how noisy it is. We bought a Bosch Sky with our own money to replace a kettle full of limescale, used it every day, and compared it with 13 other kettles sold in the UK, from a £39.99 Bosch to the Smeg icons.
The short answer: the Bosch Sky is the best everyday kettle we have used, with its controls always facing you on the base and seven temperatures at one touch. For temperature control for less, choose the Ninja Perfect Temperature Kettle or the Bosch Styline. On a tight budget, the quiet Bosch MyMoment Serene does the basics well. For looks, the Smeg KLF03; for pour-over coffee, the Dualit Pour Over Kettle.
Our picks
- Best overall: Bosch Sky TWK7203GB (£99 to £104.99). Touch controls on the front of the base, 7 temperatures, keep warm, double-walled steel. Our score: 8.5/10.
- Best value temperature control: Ninja Perfect Temperature Kettle KT201UK (£79). 6 presets plus 5°C steps from 40°C, a live temperature display and a 30-minute hold.
- Best budget Bosch with controls on the base: Bosch Styline TWK8633GB (RRP £84.99, often around £60). The Sky’s idea for less, with 4 temperatures.
- Best cheap and quiet kettle: Bosch MyMoment Serene (£39.99). Quiet Mark certified, 1.7 litres, water scale on both sides.
- Best design: Smeg KLF03 (£129.95 to £189.95 depending on colour). The 1950s look in a dozen colours.
- Best for pour-over coffee: Dualit Pour Over Kettle (£99). Gooseneck spout, 1°C steps from 38°C to 100°C.
How we chose: 14 models analysed, 1 tested hands-on
We compared 14 electric kettles that UK buyers are most likely to consider: Bosch Sky, Bosch Styline, Bosch MyMoment Serene, Ninja Perfect Temperature, Smeg KLF03 and KLF04, Sage Smart Kettle and Compact Kettle Pure, De’Longhi Eclettica, Kenwood Dawn, Dualit Architect and Pour Over, Russell Hobbs Calm and Fellow Stagg EKG.
- Bosch Sky TWK7203GB, bought by Michaël for £104.99 RRP to replace his old kettle, and used every day since for tea, the odd green tea and a cafetière. Read the full Bosch Sky kettle review.
For the other models we read the brands’ UK product pages and the John Lewis listings (capacity, power, temperature settings, keep warm time, Quiet Mark certification), compared usual UK prices at John Lewis and the brands, and read owner ratings. Our own test gave us the grid we used to judge them.
What our testing taught us
Michaël expected choosing a kettle to take five minutes. It did not:
Kettles push design very hard, but once you look past the colours and the curves, they are surprisingly hard to tell apart on actual features.
Living with the Bosch Sky showed which details actually change your day:
- Where the controls are. Most kettles have their switch at the back of the handle, so you turn the jug round to find it. Controls on the front of the base (Bosch Sky, Bosch Styline, Ninja, Sage, Smeg KLF04) are always in the same place. “It becomes muscle memory: you always know where the button is, and your hand goes straight to it.”
- Temperature control you actually use. If choosing 80°C takes one touch, you use it for green tea or coffee. If it means fiddling with buttons, you will not.
- The water window. The Sky’s one real flaw is a narrow window that is hard to read. “Very often I find myself leaning in and gently shaking the kettle to see the level move.” Check the window before you buy, especially if you like to boil only what you need.
- Keep warm time varies a lot: 5 minutes on the Dualit Pour Over, 20 on the Sage Smart Kettle and Smeg KLF04, 30 on the Bosch Sky, Bosch Styline, Ninja and De’Longhi Eclettica, up to 60 on the Fellow Stagg EKG.
- A double-walled body keeps the outside touchable and the water hot for longer. Michaël would not buy a kettle without one now.

Not in the table: the Russell Hobbs Calm (Quiet Mark certified, with colour-changing lights and optional soothing sounds) and the Fellow Stagg EKG, a 0.9 litre gooseneck kettle for coffee lovers that we found at about £139 to £165 at UK retailers. Prices and specs come from John Lewis and the brands’ UK sites; “Not stated here” means the listing we used did not give the figure.
Bosch Sky TWK7203GB: best overall
Our score: 8.5/10. The jug is just a jug: the power button, the temperature arc and the keep warm button are printed into the front of the base, so they face you however you put the kettle down. As the water heats, the arc lights up blue segment by segment. Michaël’s description:
It is like a little progress bar for your cup of tea.
Seven temperatures from 70°C to 100°C, one-touch keep warm for up to 30 minutes, a double-walled stainless steel body, a fully stainless interior with a concealed element and a removable limescale filter.
Who it’s for: tea and coffee drinkers who want a premium, family-sized kettle and use more than one temperature.
Pros: controls always at the front, temperature gauge that fills as it heats, one-touch temperature and keep warm, insulated body, 1.7 litres.
Cons: narrow, badly placed water window; keep warm stops after 30 minutes; expensive next to the Styline; some owners report lid or hinge issues after a few years.
Price: £104.99 at Bosch UK, usually £99 to £100 at John Lewis, Argos and Amazon. The white version is the TWK7201GB.

Ninja Perfect Temperature Kettle: best value temperature control
The Ninja does almost everything the Sky does, for less. Six presets from 60°C to 100°C, plus manual steps of 5°C from 40°C, all on a digital base that shows the temperature as it climbs. Hold Temp keeps the water at your chosen temperature for up to 30 minutes. Ninja says it boils one cup in under 50 seconds, and the water window lights up blue.
Who it’s for: anyone who wants real temperature control without paying Bosch Sky money.
Pros: the widest temperature range of the family-sized kettles here, live display, illuminated window, removable scale filter, 4.5/5 from almost 1,900 John Lewis reviews.
Cons: no Quiet Mark certification; the black KT200UK version costs more than the stainless steel one.
Price: £79 at John Lewis for the stainless steel KT201UK.

Bosch Styline TWK8633GB: the Sky’s idea for less
The Styline puts its controls on the front of the base too, with buttons and separate LEDs instead of the Sky’s touch slider. Four temperatures (70, 80, 90 and 100°C), keep warm for up to 30 minutes, a double-walled plastic and steel body, and a water scale that Bosch describes as easier to read than the Sky’s.
Who it’s for: anyone who likes the Sky’s controls on the base but not its price.
Pros: controls always at the front, double wall, bigger water scale.
Cons: only four temperatures, 1.5 litres instead of 1.7, plastic body.
Price: RRP £84.99 at Bosch UK, often around £60 at Bosch and Argos.
See the Bosch Styline at Bosch
Bosch MyMoment Serene: best cheap and quiet kettle
A simple 1.7 litre, 3,000 W kettle that is Quiet Mark certified, with what Bosch calls an easy-to-read water scale on both sides, a cup indicator, a 360° base, a covered element, a spout filter and cable storage in the base. Bosch says it boils one cup (250 ml) in under a minute.
Who it’s for: anyone who just boils water for tea, open-plan kitchens, early risers who do not want to wake the house.
Pros: quiet, light (0.89 kg), water scale readable from either side, 4.7/5 from about 400 John Lewis reviews.
Cons: boil only, no keep warm, plastic body.
Price: £39.99 at John Lewis.
See the MyMoment Serene at John Lewis
Smeg KLF03: best design
The kettle people buy for the way it looks. A stainless steel body inspired by the 1950s, in a dozen colours, with a soft-opening lid, a 360° base, a washable stainless steel limescale filter and anti-slip feet. It boils and switches off at 100°C; there is no temperature choice.
Who it’s for: retro kitchens and anyone matching a Smeg toaster or fridge.
Pros: iconic design, choice of colours, soft-opening lid.
Cons: expensive for a boil-only kettle; the temperature-controlled KLF04 costs even more (£169 to £199.95) and only keeps warm for 20 minutes.
Price: £129.95 to £189.95 at John Lewis depending on the colour.
See the Smeg KLF03 at John Lewis
Dualit Pour Over Kettle: best for pour-over coffee
A gooseneck kettle for filter coffee: the long, curved spout gives a slow, even pour over the grounds, and the temperature can be set one degree at a time from 38°C to 100°C, in Celsius or Fahrenheit. It holds the temperature for five minutes and is Quiet Mark certified.
Who it’s for: pour-over and V60 coffee fans. Not for a family’s tea round.
Pros: precise temperature, controlled pour, quiet.
Cons: 0.8 litres and 1,300 W, so slow for anything more than a couple of cups; 5-minute hold.
Price: £99 at John Lewis. The Fellow Stagg EKG is the cult alternative, at about £139 to £165 in the UK, with a 60-minute hold.
See the Dualit Pour Over at John Lewis
Also worth a look
- Sage Smart Kettle (£99.95): presets by drink (black, green, white and oolong tea, French press coffee), a soft-opening lid that stops splashes, 20-minute keep warm. 2,400 W, so a little slower than 3 kW kettles.
- De’Longhi Eclettica KBY3011 (£59 to £76): nine temperature settings and a 30-minute hold, the cheapest kettle here with that much choice.
- Kenwood Dawn ZJP09 (£32 to £34): another Quiet Mark certified 3 kW boil-only kettle, rated 4.7/5 at John Lewis.
- Sage Compact Kettle Pure (£69.95): a 1 litre glass kettle for small kitchens and one or two people.
- Dualit Architect (£99): customisable side panels and a window that lights up blue. Boil only.
Buying guide: how to choose a kettle
Do you need temperature control?
If you only drink builder’s tea, no: a good boil-only kettle does the job for £35 to £40. If you drink green or white tea, coffee from a cafetière or pour-over, or make baby formula, yes. As a rough guide, people often use about 70 to 80°C for green and white tea, 90 to 95°C for coffee and oolong, and a full boil for black tea. For baby formula, follow the NHS guidance and the instructions on the pack.
Capacity and power
- 1.7 litres is the standard family size, about seven cups. 1 to 1.5 litres is enough for one or two people.
- 3,000 W is the maximum for a UK plug and boils fastest. 2,300 to 2,400 W kettles (Sage, Dualit) take a little longer.
- Check the minimum fill (250 to 300 ml on most models): it decides how little water you can boil for one cup.
Features that matter in daily use
- Controls on the base rather than the handle, if you hate turning the jug round.
- A clear water window, ideally on both sides with cup markings, so you boil only what you need.
- Keep warm if you make several drinks in a row: from 5 to 60 minutes depending on the model.
- A double-walled body for a cooler outside and water that stays hot longer.
- A concealed element and removable limescale filter if you live in a hard water area.
- Quiet Mark certification if noise bothers you: the Bosch MyMoment Serene, Kenwood Dawn, Russell Hobbs Calm and Dualit Pour Over have it.
What does a kettle really cost?
Heating water takes the same energy whatever the kettle: in theory about 0.1 kWh to bring 1 litre from tap temperature (around 15°C) to the boil, before small losses. At an example rate of 25p per kWh (check your own tariff), that is about 0.6p for one 250 ml cup and about 4p for a full 1.7 litres.
- Boil only what you need. Boiling a full kettle for one cup, four times a day, adds roughly £50 a year at that example rate. A clear water window and a low minimum fill help.
- Lower temperatures save a little. Heating to 80°C instead of 100°C needs about a quarter less energy.
- The purchase price spread over the years: over five years of daily use, a £39.99 kettle costs about 2p a day, a £99 Bosch Sky about 5p a day.
Tips: limescale and descaling
In hard water areas, limescale is what kills kettles. Michaël replaced his old kettle because of it, and now descales his Bosch Sky with citric acid:
It is not a harsh chemical, it costs next to nothing compared with branded descalers, and it is very effective.
- Boil a full kettle, add a tablespoon or two of citric acid powder, and leave it to stand, up to a few hours if the scale is heavy.
- Pour it away, rinse the kettle and the filter well, boil once with clean water and throw that water away.
- Always check your manual: Bosch, for example, recommends white vinegar or a commercial descaler and warns never to scrape limescale with hard objects.
- Rinse the spout filter regularly; it stops flakes ending up in your cup.
Frequently asked questions
Best kettle UK: your questions
What is the best kettle in the UK?
For everyday use, the Bosch Sky TWK7203GB is the best kettle we have used: controls always facing you on the base, seven temperatures at one touch, keep warm and a double-walled body. We score it 8.5/10. For less money, the Ninja Perfect Temperature Kettle and the Bosch Styline offer temperature control at around £60 to £80.
Is a temperature control kettle worth it?
Yes if you drink green or white tea, coffee from a cafetière or pour-over: those taste better below boiling point. If you only drink black tea, a good boil-only kettle is enough.
What is the quietest kettle in the UK?
Look for Quiet Mark certification. Among the kettles we compared, the Bosch MyMoment Serene, Kenwood Dawn, Russell Hobbs Calm and Dualit Pour Over are certified.
How much does it cost to boil a kettle?
About 0.6p for one 250 ml cup and about 4p for a full 1.7 litres, at an example rate of 25p per kWh. Your cost depends on your tariff and on how much water you boil.
Does a 3,000 W kettle use more electricity?
No. A more powerful kettle boils faster, but heating the same amount of water takes roughly the same energy. What changes the bill is how much water you boil and to what temperature.
Which kettle is best for hard water?
One with a concealed element, a stainless steel interior and a removable limescale filter, such as the Bosch Sky or Smeg KLF03. Descale regularly whatever you buy.
How do I descale a kettle?
Boil a full kettle, add white vinegar, a commercial descaler or a tablespoon or two of citric acid, leave it for a few hours, then rinse the kettle and filter and boil once with clean water that you throw away. Follow your manual and never scrape limescale with anything hard.
What temperature should I use for green tea and coffee?
People often use about 70 to 80°C for green and white tea, 90 to 95°C for coffee and oolong, and a full boil for black tea.
Stainless steel, glass or plastic: which kettle is best?
Stainless steel is durable and often double-walled, glass lets you see the water but gets hot, plastic is light and cheap. A double-walled steel kettle like the Bosch Sky stays the most touchable.
Do I need a gooseneck kettle for coffee?
Only for pour-over coffee (V60, Chemex), where a slow, precise pour matters. For a cafetière or instant coffee, any kettle with a 90 to 95°C setting is enough.
Which is better, the Bosch Sky or the Bosch Styline?
The Sky has a stainless steel body, 1.7 litres, seven temperatures and a touch slider. The Styline has a plastic and steel body, 1.5 litres, four temperatures and buttons, with an easier-to-read water scale, for less money.
Is the Smeg kettle worth the money?
For the look, yes: it is well made and comes in many colours. For features, no: the KLF03 is boil only, and the temperature-controlled KLF04 costs more than a Bosch Sky with a shorter keep warm.
Our verdict
Most kettles boil water equally well, so buy for the details you will notice every day. The Bosch Sky gets them right: controls that always face you, a temperature gauge you can read at a glance, seven temperatures and keep warm, with only its narrow water window to forgive. The Ninja Perfect Temperature Kettle and the Bosch Styline give you temperature control for less, the Bosch MyMoment Serene is the quiet, cheap choice, the Smeg KLF03 is for looks, and the Dualit Pour Over is for coffee lovers.
