Ninja Perfect Temperature Kettle KT200UK Review: Precise, Quick and Hot to Touch
Ninja’s kettle lets you pick 60, 70, 80, 90, 95 or 100°C, or any 5-degree step from 40°C, and then holds the water there for up to half an hour. Two testers found the temperatures accurate and the boil quick. One of them also found the outside of the jug hotter than any other kettle they had tested. It now sells for about £70, well under its old £100-plus price.
Where the reviews line up
We used three sources. Trusted Reviews and Expert Reviews both tested the kettle with a stopwatch and a thermometer. The buyer ratings at John Lewis, Tesco and Currys come to more than 4,000 between them.
All three agree on the main point. The temperature control works. Trusted Reviews found the water within 1°C of the setting. Expert Reviews calls the settings precise. The six presets cover green and white teas (60–80°C), black tea, coffee at 95°C and a full boil, and the Hold Temp button keeps the water at your chosen setting for up to 30 minutes. It is quick: one litre took 2 min 24 s at Expert Reviews and 2 min 28 s at Trusted Reviews. A single cup took 48 seconds, which matches Ninja’s “under 50 seconds” claim. The minimum fill is one cup (250 ml), so you need not boil more than you drink.
The testers disagree on how much the downsides matter. Trusted Reviews’ complaints are small: plain looks and a high-pitched beep. Expert Reviews’ complaint is not small. The outside of the jug reached 78°C, the hottest of every kettle that reviewer tested, and he says it could cause a mild burn. It was also loud, peaking at 63.1 dB. He tested it at £100 and said it was not worth that, recommending the Russell Hobbs Attentiv instead.
The price has changed since then. Ninja’s own shop had it at £69.99 (was £109.99) on 10 October 2026, and Marks Electrical had it in stock at £69. At that price the case is better. Buy it if you drink green tea, make pour-over coffee or want hot water ready for half an hour. Think twice if small children can reach the worktop.
The three reviews this summary is built from
- Trusted ReviewsHands-on test: 1-litre and one-cup boil times, temperature accuracy and heat loss measured. No date or score shown.
- Expert ReviewsHands-on group test by Jamie Stedmond, 15 December 2023: boil rate, noise and surface temperature measured.
- John Lewis, Tesco & Currys4.5/5 from 1,788 (John Lewis), 4.5/5 from 1,524 (Tesco), 4.7/5 from 1,071 (Currys, white version), all checked 10 Oct 2026.
Before the review: is it still on sale?
Yes. Ninja’s UK shop still lists the black KT200UK at £69.99, down from £109.99, and Marks Electrical said it was in stock and ready to send on 10 October 2026. Ninja’s page also showed a “notify me when back in stock” box, so its own stock may run low; other shops had it. The same kettle also comes in white (KT200UKWH) and black and copper (KT200UKCP). The KT201UK is a stainless-steel version, which this page does not cover. In the US a 1500-watt model is sold as the Ninja KT200 Precision Temperature kettle. It is a different, slower product, so check for “UK” in the code.

Trusted Reviews
Who they are: Trusted Reviews is a UK tech and home review site whose editors use each product and pair that with industry-standard tests in equipped facilities; it says manufacturers don’t vet its reviews and it never takes money to test, so it is a strong hands-on source.
Trusted Reviews is the most positive of the two testers, and its numbers explain why. A litre came to the boil in 2 minutes 28 seconds and a single 250 ml cup in 48 seconds, so Ninja’s “under 50 seconds” claim held up. More important for a temperature kettle, the water was within 1°C of each setting. Hold Temp kept a full boil at 93°C. Without it, a litre cooled to 82°C in 20 minutes, which is useful to know if you make coffee at 95°C and pour slowly.
The review likes the low one-cup minimum, the wide range of settings, the clear fill marks and the pour. Its complaints are about looks and sound. It calls the design functional next to rivals such as Smeg, and the beep when the kettle starts and when it reaches temperature “slightly annoying”. It does not say whether the beep can be switched off, and we could not find out either. For comparison, the same site timed the Smeg KLF03 at 2 min 18 s for a litre. That kettle is 10 seconds quicker and much better looking, but has no temperature settings and costs more.

A UK review of the same KT200UK model. It carries the same title as the Trusted Reviews article, but the search listing did not say who made it.

Who they are: Jamie Stedmond is a Staff Writer at Expert Reviews, with the site since 2022 after starting as an editorial intern, and covers kitchen appliances and food and drink — a dedicated kitchen reviewer, which gives his critical verdict weight.
Expert Reviews tested the KT200UK alongside other kettles. It was quicker still: 2 minutes 24 seconds for a litre, a rate of 0.54°C a second. Stedmond praises the precise settings, the 30-minute hold and the recipe guide in the box. Then he lists three problems. It was noisy, peaking at 63.1 dBA. It was expensive. And the outside of the jug reached 78°C, the highest of any kettle he tested. He says that could cause a mild burn and may make it a poor choice for homes with young children or for anyone who is unsteady with their hands.
He also says it did badly in three of his four group tests, and that its features did not justify £100. His picks instead were the Russell Hobbs Attentiv and the Bosch Styline. That verdict is nearly three years old and was made at £100. At about £70 it is a closer call, but the hot jug has not changed. Trusted Reviews did not mention body temperature at all, so the two reviews do not contradict each other here; one checked and the other did not. If you want a plain 3 kW kettle that costs less and keeps its body cooler, see our Russell Hobbs Inspire review.

Another review of the UK KT200UK. Watch how the presets and the Hold Temp button are used before deciding whether you need them.

Who they are: John Lewis’ ratings are moderated by PowerReviews and include labelled free-product and prize-draw reviews; Tesco’s come from its shoppers under a policy we could not find; Currys’ are collected by Feefo from invited buyers with no incentive — all satisfaction scores, not tests.
These are large samples and they agree: owners rate it between 4.5 and 4.7 out of 5. Keep two things in mind. First, the counts may overlap. Ninja shares its reviews with some shops, and Marks Electrical showed a near-identical 4.7 from 1,069, so the Currys and Marks figures are probably the same pool. Second, none of these pages showed us any written reviews, so they tell you owners are happy but not why. They also do not tell you whether owners noticed the hot jug. Ninja’s own shop shows a lower 3.6 out of 5, with no count.
The pages are more useful for price and seller. The Tesco listing is sold by Electrical Shop through Tesco Marketplace, not by Tesco, at £69.99 (was £109.99). John Lewis had it at £99.99, so it pays to shop around. Currys had the white version at £109.99 but showed delivery as unavailable. Euronics listed £69.99 but had no local stock for us. For the cheapest price, we found Ninja’s own shop (£69.99) and Marks Electrical (£69, in stock) the best on 10 October 2026.

What holds up
- Accurate temperatures: within 1°C in Trusted Reviews’ test.
- Six presets plus 5-degree manual steps from 40°C.
- Hold Temp keeps water ready for up to 30 minutes.
- Quick: about 2 min 24–28 s per litre, 48 s for a cup.
- One-cup minimum fill, so you can boil just what you need.
- Around £70 now, against £100 to £110 before.
- Large buyer samples at 4.5 to 4.7 out of 5.
What people complain about
- The outside reached 78°C in Expert Reviews’ test, the hottest it tested.
- Loud: 63.1 dBA peak.
- A high-pitched beep at the start and at temperature.
- Plain looks next to Smeg and similar kettles.
- The second year of guarantee needs registering with Ninja.
- Not dishwasher safe, so the filter and jug are cleaned by hand.
Who it actually suits
Buy it if you drink green, white or oolong tea, make pour-over or cafetière coffee, or want water at a set temperature for formula or cooking. The Hold Temp button suits anyone who makes a second cup twenty minutes after the first. At about £70 it is one of the cheaper ways to get accurate temperature control in a 3 kW kettle. If you mainly drink espresso drinks, a machine such as the Sage Bambino Plus heats its own water, and the Nespresso Vertuo Pop does the same for pods.
Look elsewhere if young children or anyone unsteady could touch the jug, if you want a quiet kettle, or if you only ever make builder’s tea at 100°C. A plain kettle is cheaper and you will not use the presets. If lifting a full 1.7-litre kettle is hard, the lighter one-litre Tefal Includeo is easier to handle, though it is slower and has no temperature settings.
What we could not check
- Body temperature. Only Expert Reviews measured it (78°C). Trusted Reviews did not mention it, and none of the retailer pages showed written reviews where owners might. We have one measurement, from December 2023.
- Energy use. Neither tester measured kWh. Our 3.2p a litre and 1p a cup assume the kettle draws its full 3 kW for the measured times, at 26.32p/kWh. We also could not find what Hold Temp costs to run for 30 minutes.
- Whether the beep can be muted. Neither tester nor Ninja’s product page says. Ninja’s troubleshooting guide did not load for us.
- Stock at Ninja. Ninja’s page shows the £69.99 price and also a “notify me when back in stock” box. We could not tell which applied on the day. Marks Electrical confirmed stock.
- Weight and size. Ninja’s own page gives 1.24 kg and 24 cm tall in one place and 1.88 kg and 26.7 cm in another. Expert Reviews gives 1.3 kg and a depth of 10 cm, which looks wrong. Appliances Direct lists 12.4 kg, which is clearly an error.
- Buyer comments. John Lewis, Tesco, Currys and Marks show scores and counts but no review text we could read. The counts may share Ninja’s review pool, so do not add them together. Argos and AO pages did not show us ratings at all, and we found no forum discussion of this model.
- Trusted Reviews’ date and author. The page did not show them, so we cannot say how recent its test is.
- Which?. We found no public Which? result for this kettle.
- The videos were confirmed by the watch URL and title appearing in two separate search listings. We did not open them, and the listings did not name the channels.
Sources last checked 10 October 2026. Prices change often. Check the price and the model code (KT200UK) on the listing before you order, and register the kettle with Ninja within 28 days to get the second year of guarantee.
