best kettles for hard water

If you live in a hard water area such as London or the South East of England, minerals like calcium and magnesium in your tap water can leave your kettle prone to a build-up of unpleasant limescale. Limescale can not only taint the taste of your favourite morning brew, but it can also reduce the efficiency and lifespan of your kettle, meaning you may need to replace them more regularly.   

The good news is that you can buy kettles with concealed elements and limescale filters which, when combined with regular cleaning and maintenance cycles, can help combat some of the challenges of hard water. 

To bring you our pick of the best kettles for hard water, we sought out tried-and-tested reviews from Mumsnet users, gaining insights into the kettles they’ve used in their own homes in hard water areas. Combining their verdicts with the views of industry experts and consumer champions, we bring you our round-up of the best hard water kettles to suit every budget and lifestyle.

Not sure about expensive kettles, but the ones with the Brita filters are great. We have the Russell Hobbs one. It takes a bit of getting used to. Remember to fill it back up after making your drink as it takes a while to filter the water through. No scale and the filters last at least three times as long as the timer reckons. We have very hard water, I was having to descale my old kettle weekly.

Brita filter kettle all the way. I live in a very hard water area, mine has been going strong for five years and no signs of breaking yet (touches wood).

Our verdict

A stylish glass kettle with polished silver accents, this Russell Hobbs Brita Purity Kettle not only looks visually pleasing on your kitchen counter - it’s also particularly effective at dealing with the challenges of hard water. 

With an included Brita water filter, the Brita Purity Kettle helps reduce unwelcome limescale and chlorine, as well as absorbing copper and lead that can affect the taste of your tea and coffee. To continue reaping the benefits, the filter will need to be replaced regularly - roughly every four weeks depending on how often you use your kettle. While the clever built-in indicators will notify you when it’s time to replace, it’s worth factoring in the cost of the Brita replacement filters, which work out around £4.50 each from Amazon (buy here).

This kettle is simple to use, with an anti-splash ‘Perfect Pour’ spout and a 360° base with integrated cord storage to ensure a clean and uncluttered worktop. We love the blue illumination that glows when the kettle is boiling, while the glass design allows you to visually see how much water is left inside. 

The useful ‘one cup’ feature is a welcome addition to prevent water and energy wastage. However, if you’re a big household or use your kettle for cooking or entertaining, you may prefer one of our options below that can hold a larger volume of water.

  • Quick boil time

  • Large viewing window 

  • Choice of five colourways 

  • Makes up to seven cups from a single boil 

  • A detachable, easy-clean filter 

What we don't like
  • The viewing window shows litres of water rather than cups 

  • Large capacity means it can be quite heavy when full

Key specs

Price on writing: £32 | Capacity: 1.7 litres | Speed: One cup in under 45 seconds | Power: 3000W | Filter: Yes, detachable

Our verdict

With a choice of five colourways and complimenting items in the Tower Cavaletto range, this Which? Best Buy kettle is an eco-friendly choice that also makes an affordable addition to your kitchen. A great choice for hard water areas, this kettle has a removable fine mesh filter that helps successfully keep limescale at bay when cared for correctly. 

Thanks to the minimum fill level of just 235ml, the Tower Cavaletto is ideal for a single user working from home, while its 1.7-litre capacity can also cater for up to seven guests in just one boil. With a large viewing window, you can also clearly see the volume of water left inside, however, it would be more useful if the gauge was in cups as opposed to litres.

After FIVE kettles breaking in one year, I treated myself to the Sage Smart Kettle. It's amazing. It's lasted, and it's perfect for me because I drink lots of herbal teas so you can get the right temperature.

We have a Sage kettle. Have had it for about five years. It is stainless steel, and even though we live in a hard water area, it descales easily.
See Post
Our verdict

This striking stainless steel kettle may not come cheap, but with five different temperature presets, it can serve your drinks at exactly the right temperature for the best flavour and experience - ideal for those tea and coffee connoisseurs. It even has a ‘keep warm’ function, which maintains the water temperature and prevents the need to reboil. No wonder it won the top spot for variable temperature on our overall best kettles round-up too.

A cordless jug sitting on a 360-degree swivel base, the Sage Smart Kettle is ideal for both left and right-handed users, with a large easy-grip handle and soft close lid that reduces the risk of splashing and steam burns. 

While the water window can be a little tricky to read in low light, it allows you to avoid wastage by filling it with only as much water as you need - whether that's your morning brew before breakfast or a seven-cup coffee catch-up with friends. It’s worth mentioning, however, that the minimum water level is two cups, so if you’re catering for one, you’ll inadvertently be boiling more than you need.

While the limescale filter isn’t as effective as some, this stainless steel design is quick and easy to clean, making it a smart choice for hard water areas when cared for correctly.

Our verdict

A brushed stainless steel design with polished chrome details, this modern electric kettle from Cuisinart comes in four stylish colourways, each with a matching four-slice toaster for those seeking a coordinating set for their kitchen.

Whether you’re opting for a comforting cup of tea after a long day or an energising coffee to kick start your morning, the Cuisinart has multiple temperature options ranging from 85°C to 100°C, which are easy to select using simple buttons on the handle. 

We love the illuminated water window that lets you see how much water remains inside and the LCD display which clearly shows the temperature, so you won’t waste valuable energy reheating water unnecessarily. 

For hard water areas, the concealed element in this kettle results in less limescale build-up, while the easy-to-remove filter makes maintenance simple and stress-free.

De'Longhi, approaching 15 years old, in a very hard water area. Element is not visible, it’s beneath a plate at the bottom which is why I think it’s lasted so long. Descale about once every three months or when I can see a film across the tea.

I’ve got a De'Longhi that’s about 11 years old and going strong too.

Our verdict

If you’re seeking a more retro look for your kitchen, but don’t want to sacrifice on modern features, you can’t go wrong with the De'Longhi Icona range of metallic jug kettles. Available in a choice of four colourways including silver and gold, purple (plum) and blue (teal), they also have a coordinating toaster range if you wish to complete the set. 

The De'Longhi Icona Kettle can boil as little as one cup at a time (ideal for reducing water and energy use), or for cooking and larger gatherings can be filled to a capacity of 1.7 litres (around seven cups). It’s worth noting that it can be quite heavy when full, and the view of the water gauge is somewhat restricted by the handle, however, checking it carefully when filling can ensure you never boil more water than you need. 

For those in hard water areas, the De'Longhi Icona is also easy to look after and maintain, with a concealed heating element and a limescale filter that’s completely removable for cleaning.

Our verdict

If you live in a hard water area but are seeking a kettle that can last the test of time, Mumsnet users and reviewers speak incredibly highly of the Dualit Architect Kettle. With a modern and stylish design, this stainless steel kettle has a removable filter and concealed element that helps keep water away from the heat source, reducing the risk of limescale damage that can affect your kettle’s performance over time. 

We love the interchangeable panels (sold separately) that allow you to refresh the look and feel of your kettle if you decide to overhaul your kitchen colour scheme. 

While it has a smaller capacity than some, this sustainable choice has a clearly marked water gauge that helps you to only boil what you need - between one and five cups at a time. It’s not the quietest of the kettles featured, however, and can be relatively weighty when full.

Best hot water dispenser for hard water
What we like
  • Speedy 50-second boil 

  • Select from nine different cup sizes

  • Permanent limescale filter 

  • Energy efficient - only boils the water it uses 

  • Drip tray 

What we don't like
  • A traditional kettle may be more efficient when making drinks for large groups

Key specs

Price on writing: £75 |  Capacity: 1.8 litres | Speed: Less than 50 seconds for 1 cup | Power: 3000W | Filter: Yes, Brita

Our verdict

Ideal for busy parents who have always got their hands full, the Breville Brita HotCup Water Dispenser makes an energy-efficient choice, only boiling the water it dispenses at the touch of a button. Simply select from one of nine different cup sizes and dispense boiling water in less than 50 seconds - ideal when you’re a little more pressed for time. 

With a stainless steel design, convenient drip tray and Brita filter system, cleaning is also a breeze, making it easy to maintain even with the challenges of hard water. 

The 1.8-litre water tank has a capacity for up to nine cups of tea, so it is a convenient working-from-home accompaniment, however, you may find a traditional kettle more suitable for larger gatherings of friends and family. 

Best eco-friendly kettle for hard water

PHILIPS Eco-Conscious Collection HD9365/11 Jug Kettle

What we like
  • Eco-friendly design made from bio-based plastics 

  • Compact design takes up less space despite high volume 

  • Useful cup markers to help reduce waste waste 

  • Substantial capacity

What we don't like
  • Doesn’t boil as quickly as some more powerful kettles

  • Visibility of the viewing window is restricted by the handle 

Key specs

Price on writing: £50 | Capacity: 1.7 litres | Speed: Unspecified | Power: 2200W | Filter: Yes, removable

Our verdict

If an eco-friendly kettle is high up on your wishlist, the Philips' Eco-Conscious Jug Kettle is certainly worth considering. Part of a wider Collection range that also includes a toaster, coffee maker and blender, this stylish kettle is moulded from sustainable bio-based plastics to create a minimalist yet durable design. 

Alongside its green credentials, this large-capacity kettle has a built-in anti-limescale filter which helps minimise the impact of hard water during frequent use.

While this less powerful kettle doesn’t boil quite as quickly as some of the rapid boil options above, it can boil up to seven cups at a time, with a water indicator gauge to reduce unnecessary water and energy waste. 

What is hard water? 

Hard water is water that has a high mineral content and is most commonly found in London and the South East of England. The presence of minerals such as calcium and magnesium in water can result in a build-up of limescale deposits on home appliances such as kettles, washing machines, regular-sized or slimline dishwashers, plus much more.

If you live in a hard water area (you can check this via this hard water map), you need to carry out regular maintenance of your kettle to help prevent limescale build-up and prevent performance issues. 

How to choose the best kettle for hard water 

To pick the best kettle for hard water, here are some things you may want to consider:

  • Material - What is the kettle made from? Plastic kettles can be durable and hard-wearing but are often a little more challenging to clean. Stainless steel kettles tend to be the most resistant to corrosion and water damage, while glass kettles allow you to visually see when there is a build-up of limescale starting to occur.

  • Concealed elements - Kettles with concealed elements tend to be less susceptible to limescale, mostly because the part that heats up doesn’t make contact with the water. While exposed elements tend to heat up a little bit quicker, they can be more challenging to clean.

  • Filter - Does the kettle have a limescale filter? Some kettles have removable limescale filters that can trap any impurities in the water. Permanent filters need to be cleaned regularly by hand, whereas others, such as the Brita Purity Kettle need to be replaced around once a month. 

  • Cup measurements - Kettles that have a water gauge and allow low-volume boils can not only reduce the amount of energy and water used, but they can also prevent limescale build-up by only boiling the amount of water that you need. 

  • Boil dry protection - Many kettles now feature boil dry protection, which prevents the kettle from boiling when the water level is too low.

How to clean and descale a kettle

Cleaning your kettle regularly can not only improve the taste of your morning coffee, it can actually improve the efficiency and lifespan of your kettle too, so you’ll need to replace it less regularly. 

Whilst the prospect of cleaning and descaling your kettle may be a little daunting, it’s actually relatively straightforward - and can be done so with ingredients you may already have in your home. 

  • Prepare a mix of equal parts water and white vinegar - enough to fill around three-quarters of your kettle’s water tank. 

  • Boil the kettle before leaving to cool completely or simply leave for a few hours to allow the acid in the vinegar to get to work.

  • Drain the mixture away and rinse out.

  • If stubborn limescale remains, use a scrubbing brush or old toothpaste to remove any excess.

  • Boil again with clean water and repeat a few times to ensure no vinegar or limescale residue remains. 

Vinegar works really well. You need to use the clear vinegar, known as white vinegar, not the brown malt stuff you put on chips.  Fill your kettle up enough to cover the scale, pour in a very generous amount of vinegar, and leave for a few hours. You'll need to rinse out the kettle, fill it up and boil it once or twice afterwards, pouring away the water. You can repeat if it doesn't all come off the first time.” (Recommended by Mumsnet user DramaAlpaca)

How can I prevent limescale in my kettle?

While it is hard to avoid limescale completely when living in a hard water area, there are some steps you can take to prevent it:

  • Only boil as much water as you need - This uses less energy and prevents water from sitting stagnant between kettle boils.

  • Use filtered water - Boiling filtered water can help remove the calcium and magnesium build-ups found in tap water.

  • Regular cleaning - Cleaning your kettle regularly can take action on limescale before it has the chance to fully form across your kettle’s surfaces.
