It’s high (tea) time we pay more attention to our environment before it starts boiling.
We can start sipping away at our most used products and switch to more sustainable alternatives like eco kettles.
Think: better materials, designed to minimise water and energy usage, and created by a company conscious of that cuppa’s carbon footprint.
Now, care to know which are our favourite sustainable kettles?

Like all of Caraway’s non-toxic cookware, the kettle’s stainless steel body is coated in non-toxic ceramic that’s free of PFOAs and can be used on any type of stovetop including induction, electric, and gas.
It releases up to 50% less CO2 when produced compared to traditional non-stick coatings.

My Personal Review of Caraway’s Kettle:
“The Caraway Tea Kettle is as functional as it is beautiful, with a thick and sturdy design that feels durable and high-quality. It heats up quickly on my gas range and especially retains heat well, making it perfect for frequent use. We actually timed how long it took to boil the same amount of water in this kettle and our old one, and Caraway came out on top by nearly two minutes. The sleek, modern look also adds a stylish touch to my kitchen, especially since I matched all my Caraway tea towels to its color!”

These coffee capsules are mostly Fairtrade certified, too.
Used Electric Kettles
Are electric kettles eco-friendly?
Typically not, however, used electronics are the most ethical electronics—and eco-electric kettles are no different.
There are many options when it comes to sourcing used kettles. They’re a common find at thrift stores, Facebook Marketplace, Craigslist, or Gumtree.
To have a sip-worthy kettle shipped directly to your door, consider:
- eBay: eBay has a range of certified refurbished, seller refurbished, and used tea kettles. Many are made with stainless steel and some come with warranties.
- Amazon Renewed: You can find refurbished, open-box, and pre-owned kettles that are professionally inspected and tested and come with at least a 90-day guarantee. Many on offer are the best energy-efficient kettles, too.
If you’re wondering what type of kettle is more sustainable, we’d recommend looking for fully stainless steel kettles, as these are the most durable as well as the most non-toxic.
Be sure to check that the heating coils and brass fittings aren’t exposed, as they may leach nickel, lead, and heavy metals.
Electric Tea Kettle Vs. Eco Stove Top Kettle
If you’re wondering what type of kettle is more sustainable between hob kettles and electric kettles, the jury’s still out.
Choosing the most economical kettle is also somewhat confusing. Some suggest it takes the same amount of energy to heat the same amount of water—regardless of how you do it (unless the forgotten hob kettle is left to whistle away, of course).
Others recognize the potential energy wasted on the body of the kettle and the stove itself. The main drawback to electric kettles, however, is that all the electronic components and mixed materials make them difficult to recycle and tricky to dispose of.
Electronics in general have this problem, which we think makes hob kettles arguably more of a sustainable tea kettle and a little greener than their counterpart.
How To Dispose Of Old Kettles
Kettles contain components that can be toxic when they end up in a landfill.
We recommend not contributing to the UK’s annual 378,200 tonnes of electrical waste by taking it to a local recycling centre.
While the recycled components aren’t valuable, the process will yield low-value metals that can be upcycled into other products.
Because recycling is far from the solution we thought it was, the best thing you can do is to look after your kettle for as long as possible. To prevent limescale, regularly wash it with a 1:1 water and white vinegar solution by letting it soak for an hour then boiling it with plain water.
And don’t leave water sitting inside the kettle as this too will result in limescale.
How We Found The Best Eco Kettles
The world of technology is rapidly advancing. The world of sustainable technology, on the other hand, is not quite heating up at the same rate.
While truly ethical electronics are a long way off, there are things we can do to minimise e-waste and energy consumption.
Materials:
Materials for the best energy-saving kettles include mostly stainless steel, glass, and sometimes recycled plastic. Stainless steel is the most popular choice for good reason. It’s durable, heat resistant, elegant, and leaves no flavours or smells.
Glass kettles are elegant and won’t impart flavours or smells, but they can be quite fragile.
While plastic would have been avoided previously, BPA is generally no longer a concern as most manufacturers have phased it out (still something to keep in mind with used kettles).
Recycled plastic or biobased plastic are better options for the planet, but they do still produce a risk of toxicity, especially when repeatedly heated, so consider those with stainless steel linings. While plastic kettles are cheaper and lightweight, they can leave smells or odours and won’t last as long as stainless steel.
It’s also best to avoid exposed heating elements as they may be a source of nickel leaching, not to mention an obstacle to removing limescale.
Traditional hob kettles often feature materials like enamel, copper, and cast iron, which can leach metals and other toxins into your tea.

Energy Usage:
In British homes, a whopping 6% of electricity is used by the kettle. Continuous cuppas mean kettles use more electrical energy than kitchen hobs, ovens, and microwaves.
While electric kettle wattage ranges from 1500W to 3000W, this will influence the heating time (higher W = faster) and won’t have an impact on energy usage. The best energy-efficient kettle is not one with a certain wattage, but rather one equipped with insulated walls, auto shut-off, and one-cup water heating features.
The most important thing is to fill the kettle with only the amount of hot water you need!
It takes no time to measure a cup of water to heat or use the handy water level of your eco-friendly kettle if it has one. Simply doing this will save more than 3% on your electricity bill. Regularly descaling it (especially if it lacks a limescale filter) will also help, and be sure to unplug it after use to prevent phantom energy draws.
Recyclability & Repairability:
Fortunately, many eco-electric kettle brands are making a significant effort to help replace and repair kettles. Look for specific brands that back their products with extended warranties and offer options to recycle or repair the broken ones.
FAQ: Non-Toxic Kettles
What is the main purpose of the article?
We’re highlighting a selection of our favorite kettles that meet higher sustainability and health criteria — made with non-toxic and durable materials, designed to minimise energy and water waste, and produced by brands with more sustainable practices — so that tea and coffee lovers can choose better ones.
What defines an “eco-friendly kettle”?
In a nutshell, an eco-friendly kettle is one made from safe materials (like stainless steel, glass, or ceramic —not plastics or coated metals with toxic finishes), designed for efficient boiling and minimal waste, often with ethical manufacturing and transparent supply chains.
Why should someone consider switching to an eco-friendly kettle?
Because many conventional kettles contain plastic parts, coatings that may leach, or inefficient designs that waste electricity and water — switching to a well-designed, non-toxic kettle helps reduce your carbon footprint, exposure to harmful substances, and energy/water use.
What materials should a buyer look for in a sustainable kettle?
There are a few materials which you should prioritize, specifically these non-toxic options: food-grade stainless steel, borosilicate glass and pure ceramic. You also want to opt for minimal or no plastic, or ensure the plastic components of the kettle do not come into contact with boiling water. Also look out for energy-efficient boiling/insulation, eco-conscious packaging, and good manufacturing ethics (e.g., transparent supply chain).
Are electric kettles better than stovetop kettles?
We cover both formats (electric and stovetop) but emphasise that regardless of type, the material, design efficiency and production ethics matter most when evaluating sustainability and non-toxicity.
Final Thoughts On Eco-Friendly Tea Kettles
Are eco kettles worth it? Absolutely.
