Kettles in the UK currently range from £13.65 to £132.99, with the typical price sitting around £40.82. Spend less and you get the basics done reliably; spend more and you gain stainless steel internals, quieter boils, and precision pour spouts. This guide breaks down what each price band actually delivers so you can stop at the right shelf.
What to look for
01Under £20: Functional plastic, 3 kW boil, nothing fancy
At this end of the market, you are paying for the core job: boiling 1. 7 L of water on a UK 240V mains supply at 3 kW. The Daewoo Essentials 1.7L sits at £13.65, the cheapest of the 27 kettles tracked here, and it delivers auto shut-off and boil-dry protection. The Russell Hobbs Textures (£19.99) adds a removable, washable anti-scale filter, which matters in hard-water areas such as London, the South East, and the Midlands where limescale builds up fast. Expect matt or gloss plastic bodies, push-to-open lids, and water-level windows. Build quality is adequate for a few years of daily use, but internal plastic components do contact the water, which is worth noting if you are sensitive to taste. Discounts at this tier are common: the Russell Hobbs Textures has traded as low as £8.00 in the past 90 days, so watch for sales.
02£20 to £35: Better materials, higher review counts, more colour choice
This is the sweet spot for most households. The Russell Hobbs Honeycomb range (£19.99 to £23.99 depending on colour) sits here, offering 3 kW fast boil, a removable anti-scale filter, and a push-button lid in white or grey finishes that blend into standard 600 mm kitchen worktops. The Chefman Glass 1.8L (£22.99) swaps plastic for a glass body, so you can see the water level and limescale build-up at a glance. Glass does not impart any taste, which tea drinkers often prefer. At this price you also start to see LED illumination, no-splash spout designs, and BPA-free certification becoming standard. The Cosori Black (£29.99, with a 90-day low of £18.00) adds a food-grade stainless steel filter and inner lid, meaning no plastic touches your water at all. Average discounts across tracked kettles run at 9.7% off the 90-day high, so this tier rewards patience.
03£35 to £70: Stainless steel, quieter operation, longer warranties
Once you cross £35, plastic bodies largely disappear. The Cosori Brushed Stainless Steel 1.7L (currently £70.99, though its 90-day low is £27.98) is a good example of what this tier can offer: no plastic in contact with water at any point, a durable brushed finish that hides fingerprints, and a 3,000 W element for a full boil in around three minutes. Stainless steel kettles also tend to be quieter during boiling because the material dampens vibration better than thin plastic. If you live in a hard-water area, a stainless steel interior is easier to descale with a standard citric acid solution. Sizing stays consistent at 1.7 L, which fits most UK under-cabinet clearances without issue.
04Travel kettles: a separate category with different priorities
The Russell Hobbs Travel Kettle 0. 85L (£14.99) is not a budget compromise on a full-size kettle. It is a purpose-built product with dual voltage (suitable for both UK 240V and overseas 110V to 120V supplies), a compact 0.85 L capacity, and a 1,000 W element. That lower wattage is deliberate: many European and US sockets cannot handle 3 kW. It comes with two cups and spoons, making it self-contained for caravanning, camping, or hotel stays. The 90-day price has held steady between £13.33 and £14.99, so there is little reason to wait for a sale. Do not judge it against full-size kettles on boil speed; judge it on portability and voltage flexibility.
05When to buy: discounts and timing
Across the 27 kettles tracked, the average discount off the 90-day high price is 9. 7%. The biggest current deal is the Tefal Loft 1.7L 3,000 W kettle at 17.2% off, saving £5.00 on its recent high. Kettle prices dip most reliably around Amazon Prime Day (usually July), Black Friday, and the January sales. If you are buying a mid-range model in the £25 to £40 bracket, checking the 90-day low before purchasing can save you £5.00 to £10.00 without any compromise on the product itself. Price-tracking browser extensions work well for this category because prices fluctuate frequently and the savings are proportionally significant at lower price points.
Our top picks
Best for tight budgets who just need reliable boilingDaewoo Essentials 1.7L Fast Boil Electric
At £13.65, the Daewoo Essentials 1.7L is the cheapest of the 27 kettles tracked and still covers the essentials: auto shut-off, boil-dry protection, and a cordless 360-degree base. It is a no-frills plastic jug kettle, but for a student flat, a spare room, or a garden office, it does exactly what is needed without any financial risk.
Best mid-range pick with plastic-free water contactCosori Kettle
The Cosori Black 3,000 W kettle is currently £29.99 but dropped to £18.00 in the past 90 days, making it worth watching for a price dip. Its food-grade stainless steel filter and inner lid mean no plastic contacts your water, a genuine step up from most kettles at this price. The LED ring and no-splash spout are practical rather than decorative.
Best all-rounder for everyday family useRussell Hobbs Honeycomb Electric 1.7L Cordless
The Russell Hobbs Honeycomb White (£23.99, 3 kW, 1.7 L) has 8,260 reviews averaging 4.6 out of 5, the highest rating in this group. The removable washable anti-scale filter is particularly useful in hard-water areas, and the push-button lid and perfect-pour spout make daily use genuinely easy. It has held its current price as its 90-day high, so it is consistently priced rather than artificially inflated.
Best for travel, caravanning, and overseas useRussell Hobbs Electric 0.85L Travel Kettle
The Russell Hobbs Travel Kettle (£14.99, 1,000 W, 0.85 L) runs on dual voltage, covering both UK 240V and international 110V to 120V supplies. It includes two cups and spoons, a removable anti-scale filter, and water-level windows on both sides. At 0.85 L it boils only what you need, which saves time and energy on the road.
Best glass kettle for tea drinkers who want to see the waterChefman Glass Electric Kettle 1.8L 3000W
The Chefman Glass 1.8L runs at 3,000 W and is BPA free, with a glass body that lets you monitor water level and limescale build-up without lifting the lid. At £22.99, it sits comfortably in the mid-range and has traded as low as £19.99 in the past 90 days. Glass does not affect water taste, which matters if you brew loose-leaf tea.
Frequently asked
How much should I spend on a kettle in the UK?
Most UK buyers will be well served spending between £20.00 and £35.00. At that level you get a 3 kW fast boil, a removable anti-scale filter, and either a glass or stainless steel interior that keeps plastic away from your water. Below £20.00 you get a functional kettle with fewer material upgrades. Above £70.00 you are paying for premium finishes, quieter operation, or brand prestige rather than meaningfully better tea.
Is a 3 kW kettle worth it compared to a lower wattage one?
On UK 240V mains, a 3 kW element boils a full 1.7 L in roughly three minutes. A 2.2 kW element takes closer to four and a half minutes. Over a year of multiple daily boils, the time saving adds up noticeably. Energy consumption per boil is similar because both elements heat the same volume of water to 100°C; the 3 kW version just does it faster. For travel kettles, lower wattage (1,000 W) is necessary to work safely on international sockets.
Do I need an anti-scale filter if I live in a hard-water area?
Yes, it helps. Hard-water areas, which include most of London, the South East, East Anglia, and the Midlands, deposit limescale on heating elements and inside spouts. A removable washable filter catches flakes before they reach your cup. It does not prevent scale building on the element itself, so you still need to descale every four to six weeks with a citric acid solution or a proprietary descaler. A filter is a convenience feature, not a substitute for descaling.
What is the cheapest kettle worth buying right now?
The Daewoo Essentials 1.7L at £13.65 is the lowest-priced kettle in the current tracked range and is a reasonable buy for basic use. It includes auto shut-off and boil-dry protection, which are the two safety features you should not compromise on. If you can stretch to £19.99, the Russell Hobbs Textures adds a washable anti-scale filter, which is a meaningful upgrade for hard-water households.
Are there good kettle deals to be had right now?
Yes. The Tefal Loft 1.7L 3,000 W kettle currently has the biggest discount in the tracked range at 17.2% off its 90-day high, saving £5.00. Across all 27 tracked kettles, the average discount off the 90-day high is 9.7%. The Cosori Black has also dropped to £18.00 in the past 90 days against a current price of £29.99, so checking recent price history before buying is worthwhile.
