Quick verdict
Smeg 50's Retro KLF04PBUK Kettle with Temperature Selector is a premium, design-led buy rather than a budget pick. At £189, it makes the most sense if you want the Retro look, the pastel-blue finish and variable-temperature control for different drinks, and you are happy to pay more than many competing kettles.

What the product page tells us
AO.com returned a protection page when we checked the listing, so this review stays close to what is confirmed: the title is Smeg 50's Retro KLF04PBUK Kettle with Temperature Selector, the tracked colour is Blue / pastel blue, and the current tracked price is £189. Because the live retailer page was not fully accessible, live stock, delivery charge, final checkout price and any model-specific specification details should be verified on the retailer page before you buy.
Key takeaways from wider product context
The KLF04 family sits in Smeg’s variable-temperature kettle range, which makes the selector more than a decorative extra for tea and coffee drinkers who care about water temperature. The strongest visible review details is a broad 4.7 out of 5 from up to 3,044 reviews, but the exact KLF04PBUK pastel-blue listing appears to have thinner standalone review coverage, so treat the rating as family-level reassurance rather than proof of this exact model’s long-term performance. That matters because public review themes are mixed: styling and temperature control are praised, while value-for-money and reliability concerns still appear in the wider KLF04 discussion.
Buyer trade-offs to weigh up
The main trade-off on the Smeg 50's Retro KLF04PBUK at £189 is whether you will actually use the variable-temperature control often enough to justify paying more than simpler kettles. If your household mostly wants a quick boil-and-pour machine, cheaper alternatives will usually make more sense; if you brew different drinks and want Smeg’s pastel-blue Retro styling on the counter, the extra spend is easier to defend. It is also worth weighing how much colour match matters, because the Blue finish is part of the appeal alongside the feature set.
Price and value benchmark
At £189, this sits well above the comparable-product median of £104, which is why it reads as a premium purchase rather than a standard kettle buy. Among 52 comparable kettles, 41 are cheaper and only 5 are dearer, so the price position is clearly on the high side. That does not make it poor value automatically, but it does mean the case for buying it rests on design appeal, the variable-temperature feature and brand preference more than on headline price.
Specs versus nearby alternatives
Public context for the KLF04 family points to a 1.7-litre capacity, 3000W power and a 360-degree base, which are useful mainstream kettle specifications for a busy kitchen. Against nearby alternatives, the key question is whether you need temperature selection at all, because simpler Smeg Retro kettles such as the KLF03 line can come in similar styling without the same feature focus. If you are comparing options purely by spec versus price, check whether a lower-priced kettle with a similar capacity and base setup covers your needs before paying extra for the KLF04 family’s temperature control.
How to read the review evidence
The visible owner-rating details is strong at 4.7 out of 5 from up to 3,044 reviews, but it is not clearly tied to this exact AO pastel-blue listing. Public review coverage is broader for the KLF04 family than for KLF04PBUK specifically, so the number is best treated as useful context rather than a guarantee of this exact unit’s day-to-day experience. That is especially relevant because the wider family feedback includes praise for looks and ease of use, alongside complaints about leaks, lid or button issues and value concerns on some units.
Who it suits
This Smeg 50's Retro KLF04PBUK suits tea and coffee drinkers who will actually use variable temperature settings and want a premium-looking appliance on the worktop. It also suits shoppers comparing premium kettles in the £189 bracket who care about colour choice, because the pastel-blue finish is part of the purchase decision as much as the kettle itself. If you are weighing up a Smeg variable-temperature kettle against similar branded options, this is the type of model that is bought as much for the feel and finish as for the basic boiling function.
Who should avoid it
Budget buyers should look elsewhere, because £189 puts this far above the category median and the value case depends on style and feature use. It is also less compelling if you do not need temperature selection, since the main reason to choose the KLF04 line is the variable-temperature setup rather than a simple lower-cost boil-and-pour kettle. Shoppers who are wary of mixed family-level review feedback around reliability or who want the lowest possible ownership cost should compare cheaper alternatives first.
Everyday comfort and practical fit
The useful everyday questions are whether the kettle fits your kitchen visually, whether the 1.7-litre family size is suitable for your household, and whether you will benefit from the 360-degree base and temperature selector. Those are the details that matter more than decorative Retro styling once the kettle is on the counter every day. Before ordering, check delivery terms, warranty coverage and live stock on AO, because premium appliances can vary in availability and aftercare as well as in price.
Value judgement
This Smeg only feels good value if you specifically want the premium look, the pastel-blue colour and the temperature-control feature set enough to justify the £189 price. If you mainly want a reliable kettle at the lowest cost, cheaper options will be easier to defend on value alone. Compare the latest price and stock against alternatives on AO before buying, because the best choice here depends on how much you value style, brand and drink-specific temperature control.

Questions about this electrical
Is the Smeg 50's Retro KLF04PBUK worth the premium over cheaper kettles?
It can be, but only for shoppers who value the Retro design, pastel-blue finish and variable-temperature control. At £189, it sits well above the category median, so cheaper kettles are usually better on pure price unless those extras matter to you.
Does the temperature selector matter for tea and coffee, or is it a nice-to-have?
For households that brew different drinks, it is a genuinely useful feature rather than just a design extra. If you only boil water for general use, the selector is easier to live without and you may get better value from a simpler kettle.
How much confidence should I place in the 4.7-star rating if it covers the wider KLF04 family?
It is a helpful sign of strong buyer interest, but it should not be treated as proof of this exact pastel-blue AO listing’s performance. The review trail is broader for the KLF04 family than for KLF04PBUK specifically, so verify the live AO page and recent reviews before ordering.
Is the pastel-blue finish available, and does colour affect the price?
The tracked variant is Blue / pastel blue, and the current tracked price is £189. Colour can affect the appeal of the purchase, but you should still check the live AO listing for stock, final checkout price and any variant changes before buying.
What should I check on AO before buying: stock, delivery and final checkout price?
Check all three before you order, because the AO product page was not fully readable when this review was compiled. Confirm stock status, delivery cost and the final checkout price so the £189 comparison stays accurate.
