It’s a question that often arises when people hear concerns about plastic, metals, or coatings in appliances that heat water. The short answer is: no, an electric kettle does not cause cancer when properly used and made from safe, certified materials.
However, it’s important to understand where these concerns come from, what to look for in a safe electric kettle, and why reputable manufacturers such as Hughes Coffee design their kettles to meet strict international safety standards.
Health concerns typically focus on two things:
The materials used in the kettle, especially plastics and coatings.
The possibility of chemicals leaching into boiling water.
Because electric kettles heat water rapidly to 100°C (212°F), people sometimes fear that heat could release harmful substances — such as BPA or heavy metals — from low-quality components.
But in reality, these risks are linked only to cheap, uncertified products that don’t comply with modern safety standards.
High-quality 304 or 316 stainless steel (also known as food-grade steel) is chemically stable and does not release toxins when heated.
Resistant to corrosion and oxidation.
Completely BPA-free.
Commonly used in surgical and food equipment.
Conclusion: Stainless steel electric kettles are very safe for daily use and pose no cancer risk.
Tempered or borosilicate glass kettles are inert and heat-resistant, meaning they don’t react with water even at boiling temperature.
Free from chemicals like BPA or phthalates.
Transparent — you can see if scale builds up.
Conclusion: Glass kettles are one of the healthiest options for boiling water.
This is where concerns usually arise. Some older or low-quality plastic kettles may contain BPA (Bisphenol A) or phthalates, which can leach into water if the plastic is exposed to high heat for long periods.
BPA has been linked in some studies to hormone disruption — but not directly to cancer when exposure levels are within safe limits.
Modern, certified plastic kettles use BPA-free materials that are tested for food safety.
Conclusion: Use only BPA-free, food-grade plastic kettles from trusted brands, and avoid using any kettle that smells strongly of plastic even after multiple uses.
Reputable kettle manufacturers adhere to international health and safety certifications that prevent the use of hazardous materials.
CE / UKCA – European and UK product safety compliance.
FDA Food Contact Safe – U.S. food-grade certification.
RoHS – Restriction of hazardous substances (no lead, cadmium, mercury, etc.).
LFGB (Germany) – Strict testing for food-contact materials.
Hughes Coffee electric kettles are CE- and ISO9001-certified, ensuring every component that contacts water is non-toxic, corrosion-resistant, and BPA-free.
Even with a safe kettle, proper use keeps your water pure and your appliance in good condition.
Choose stainless steel or glass kettles over full-plastic models.
Clean regularly with vinegar or citric acid to remove limescale buildup.
Avoid overheating or leaving water to reboil multiple times.
Use filtered water to reduce mineral deposits and contaminants.
Use a cheap, unbranded kettle with unknown material origins.
Boil milk, soup, or sugary liquids inside — this can burn and damage the coating.
Keep boiled water sitting inside for long periods.
When maintained properly, an electric kettle is one of the safest and most hygienic appliances in your kitchen.
Scientific studies show no direct link between using electric kettles and cancer.
Stainless steel, glass, and BPA-free plastics are non-carcinogenic materials.
Modern kettles undergo migration testing, ensuring no harmful chemical transfer into water.
Reboiling water occasionally does not make it toxic — as long as you’re using clean water and a safe kettle.
In short, fears about cancer from electric kettles are unfounded when products meet global safety standards.
Hughes Coffee designs premium stainless steel electric kettles built with food-grade materials and multi-layer safety systems to ensure both performance and health protection.

CE and ISO9001 certified for international safety compliance.
Temperature control to avoid unnecessary overheating.
These design standards eliminate any risk of harmful chemical exposure — ensuring your daily cup of coffee or tea is both safe and pure.
| Material | Cancer Risk | Safety Level | Recommended Use |
|---|---|---|---|
| Stainless Steel | None | ★★★★★ | Best option |
| Glass | None | ★★★★★ | Great for visibility & purity |
| BPA-Free Plastic | None | ★★★★☆ | Safe when certified |
| Old / Cheap Plastic | Possible | ★☆☆☆☆ | Avoid completely |
No, electric kettles do not cause cancer — provided they are made from safe, certified materials and used correctly. Concerns arise only with low-quality, non-certified products that use unsafe plastics or coatings.
For peace of mind and long-term health, always choose trusted brands like Hughes Coffee, whose stainless steel electric kettles meet the highest food safety and manufacturing standards.
