We analysed the Amazon.co.uk subcategory Kettles & Tea Machines and kept only products with at least 200 reviews and 4.3 stars. Ranked by estimated monthly revenue, Russell Hobbs holds six of the ten places between £13.99 and £38.49, the three temperature-selectable Ninja models sit at £79 and above, and one entry is not a kettle but a hot water dispenser.
The revenue leader by a wide margin: at £79 it earns more in a month than the two least expensive kettles on this page put together.

The brushed steel standard at £34: 3 kW, a quiet boil claim and a washable limescale filter, with nearly 25,000 reviews behind it.
The same KT200UK as rank 1 in black and copper — identical £79 price, identical review pool, listed by Amazon as a separate product.
Sits £8 under the 20460 at rank 2 and fell 40% during the observed period — the steepest price drop in this comparison.
The newest Ninja here with only 278 reviews, and the most expensive kettle in the list at £99.99 after a 43% price rise.
Not a kettle: it boils and dispenses one cup at a time from a 2 litre tank, which is why it is sold on running cost rather than speed.
£23 for a plastic-bodied 1.7 litre with the same 3 kW element quoted on the steel models — the honeycomb texture is most of what you are choosing.
The most reviewed product in this comparison at 35,390 ratings, and at £19.99 the least you can pay here for a full 1.7 litres.
The lowest price here at £13.99 and a different job entirely: 0.85 litres at 1000 W, dual voltage, with two cups and spoons in the box.
The glass-bodied option at £38.49 — it lights up as it boils, and it is the one kettle here where limescale is permanently on show.

Green and white tea want 70 to 85 °C; boiling water scalds the leaf and turns it bitter. The three Ninja models here let you pick and hold a temperature, and that single feature is the whole reason they cost £79 to £99.99 against £20 for a kettle that only knows 100 °C.
Every full-size kettle in this list quotes 3 kW and boils a mug in well under a minute. The 1000 W travel model takes several times as long, and that is the trade for dual voltage and a body that fits in a suitcase.
In hard-water Britain the scale filter is the part you handle most. Every Russell Hobbs here quotes a removable washable anti-scale filter — check it pulls out from the spout without tools, because one that does not simply never gets cleaned.
Glass shows the water level and every fleck of scale, and it is the material most likely to chip. Plastic is the light, cheap option and dominates the sub-£25 end. Brushed steel hides scale but shows fingerprints — none of the three changes how the water tastes.
A hot water dispenser boils only the cup you asked for, which is cheaper if you drink one mug at a time and slower if you are filling a teapot for four. One entry here is a dispenser rather than a kettle, and that is worth knowing before you compare its price with the rest.
A push-button lid opens one-handed while the other hand holds the tap. A narrow pour spout matters when you are filling a cafetiere or a teapot rather than a mug, and a water window stops you boiling a litre for one cup.
If you drink green, white or oolong tea, or brew pour-over coffee, then yes — those want 70 to 92 °C and a standard kettle only offers 100 °C. If it is builder's tea and instant coffee, you are paying £60 for a display. The three Ninja models here are the only ones on this page that offer it.
Amazon files the Breville HotCup in this subcategory. It holds 2 litres cold and boils each cup as you dispense it, so it is neither a kettle nor an urn. We have left it in the data and labelled it rather than removing it, because it is genuinely one of the biggest sellers here.
The matte black KT200UK and the black and copper KT200UKCP are colourways of one kettle, and Amazon pools their 4,523 reviews. Both sell for £79. If you have no colour preference, buy whichever has stock, because the product underneath is identical.
The products are ordered by estimated monthly revenue per ASIN, not by star rating and not by bestseller rank. Only products with at least 200 reviews and an average of 4.3 stars were included. Because revenue is price multiplied by units, the £79 Ninja outranks a £14 kettle that sells more of them.
The score is not our own hands-on test. It is calculated transparently from public Amazon data: 75% from the average star rating and 25% from the number of reviews, weighted logarithmically. The ranking order itself comes from estimated monthly revenue per ASIN. Prices, ratings and review counts were retrieved from Amazon.co.uk on 22 July 2026 and can change at any time.
