There's an entire category of kitchen review where the honest answer is just "buy the cheap one." Electric kettles are this category. The £30 Russell Hobbs Inspire boils water reliably, has a cordless base, has a water-level indicator, and lasts five-plus years. There is genuinely nothing more a kettle needs to do for most households.
The £180-£200 premium kettles exist for specific use cases — primarily pour-over coffee and certain tea preparations — and aren't worth the price for most UK households making cups of tea. The Smeg KLF03 at £180 looks lovely on a kitchen counter and adds temperature control that tea enthusiasts will use. The Fellow Stagg EKG at £190 has a gooseneck spout designed for V60 pour-over. Both are real products solving real problems for real people. They are not the right answer for someone making three cups of breakfast tea a day.
What you're actually buying at each price tier
£30-£45: a kettle that boils water. Cordless base, water-level indicator, 1.7L capacity. Done.
£100-£140: better build quality, more design, broadly the same function as the £30 kettle. Mostly aesthetic.
£140-£180: temperature control becomes available — useful for green tea (80°C) versus black tea (boiling) versus coffee bloom (94°C). Genuine functional addition.
£160-£190: gooseneck pour control for pour-over coffee. Specific use case; if you don't do pour-over, irrelevant.
The four worth knowing
Russell Hobbs Inspire at £30-£45. Functional electric kettle. Boils water reliably, has cordless base, water-level indicator, removable filter. 1.7L capacity, rapid boil. The right answer for most UK households. There genuinely isn't more to say about a £35 kettle that works.
Smeg KLF03 at £140-£180. Retro-style design object. Temperature control adds genuine value if you make different teas (green tea at 80°C, black tea at boiling, etc.). Build quality is good for the price tier. Best for households who care about kitchen aesthetics and make varied teas.
Fellow Stagg EKG at £160-£190. Gooseneck spout designed specifically for pour-over coffee preparation. Temperature control to 1°C precision; the gooseneck enables controlled pour rate. Right tool for pour-over enthusiasts (Hario V60, Chemex, Kalita Wave). Dramatically over-engineered for households making French press or instant coffee.
KitchenAid Architect at £100-£140. Premium build, metal construction, 1.7L capacity. Genuinely durable but sits awkwardly between the Russell Hobbs (cheaper, equivalent function) and Smeg (more design-led).
How I'd actually pick
Most UK households: Russell Hobbs Inspire. No question. £35 buys a competent kettle that lasts 5-plus years. Don't overthink this.
Pour-over coffee enthusiasts: Fellow Stagg EKG. The temperature precision and gooseneck genuinely matter for the use case.
Households who care about kitchen aesthetics and make varied teas: Smeg KLF03. The premium is partly aesthetic, partly the temperature control feature — both legitimate reasons to pay it if they apply to you.
What I'd swerve: paying £100-plus for a kettle whose primary differentiator is "looks nice" without functional benefit. Some Dualit and KitchenAid models fall in this category — well-made, but not meaningfully better at boiling water than the £35 alternative.
