A stylish glass kettle with brushed stainless steel accents, this Russell Hobbs makes a great addition to a modern kitchen. It's powerful and efficient, and we love that it illuminates with a blue glow during the boil. There's also a clearly marked ‘1 cup’ measurement on the exterior to help prevent water and energy wastage.
The concealed element and removable mesh filter on this cordless electric kettle can help slow limescale build-up, and the transparency of the glass means you have a handy visual indicator of when it's time to use a kettle descaler.
In addition, the convenient 360-degree swivel base is suitable for right and left-handed users. However, the cord is a little on the short side, so you’ll need to position it close to your plug sockets.

If you’re looking for a budget-friendly glass kettle, they don’t come much more affordable than the Iridescent Glass Kettle from ASDA. Despite retailing at less than £20, this glass kettle has many of the features seen in more costly models, including a powerful 3KW element, boil-dry protection and a clearly marked one-cup indicator so you can boil only the water you need.
While it boils water quickly, it runs a little louder than some of our other picks while boiling. It’s also worth noting that the iridescent design isn't completely transparent, so it can be a little trickier to read the water scale when full.
Best glass kettle for hard water
Russell Hobbs Brita Filter Purity Glass Kettle
Concealed element
Brita Maxtra+ Filter Cartridge with clear replacement indicator
Blue illumination
Powerful with rapid boil
Energy efficient '1 cup' feature
Less capacity than our best pick Russell Hobbs glass kettle

The Russell Hobbs Brita Purity was the clear winner on our best kettle for hard water round-up. Thanks to the Brita water filter, it reduces unwelcome limescale and chlorine, as well as absorbing copper and lead that can affect the taste of your cup of tea or coffee.
While it's worth factoring in the cost of replacement filters (which work out around £4.50 per month from Amazon), many reviewers claim it's worth it for cleaner, clearer water. There's also a handy built-in indicator that alerts you when its time to replace.
We love the energy-efficient 'one-cup’ marker, which prevents you from boiling more water than necessary, while the ‘perfect pour’ spout reduces the risk of splashing when serving up your favourite brew.
However, it’s worth highlighting that the Purity model only has a 1-litre capacity, which may be restrictive for large families.

While most kettles will boil your water to precisely 100°C, the delicate flavours of some hot drinks like herbal teas or French press coffee can turn bitter if they are served too hot. If you know the difference between your green teas and your oolong, the Cookworks Variable Temperature Kettle allows you to serve hot water at one of four specific temperatures to keep them tasting their best.
While the minimum boil is two cups, we love the handy keep-warm function on this kettle - it's a great way to reduce your energy consumption by preventing the need to reboil. This stylish glass kettle is also easy to clean and maintain thanks to the removable and washable limescale filter.

What Mumsnet users say
If you have a small kitchen or simply want a glass kettle that doesn’t take up valuable counter space alongside your toaster, Sage's The Compact Pure is an excellent choice.
While its four-cup capacity makes it less suited to large gatherings, this small but perfectly formed kettle is both stylish and practical, with highlights being its diminutive footprint, ergonomic handle and easy-to-use multi-directional base.
We love the soft top lid that prevents splashing, while the concealed element and durable stain-resistant glass design help keep unsightly limescale at bay.

With a sleek glass and stainless steel design, the Logik L17GK22 Jug Kettle features blue LED lights that illuminate during the boil, helping you brew a comforting cuppa even in low light.
We love this kettle’s reasonable price point and the convenient 360 base. While its transparent design makes it easy to see the volume of water inside, the minimum capacity is 500ml (two cups). As a result, it’s not the most energy-efficient choice if you only need drinks for one.
Are glass kettles any good?
While a topic of much debate on the Mumsnet forums, those who love glass kettles praise them for their modern and stylish designs, ease of cleaning and sustainable materials.
The transparent design provides good visibility, allowing you to boil only the amount of water you need, reducing water wastage and saving energy as a result.
The disadvantage, particularly in a hard water area, is that is quickly apparent when limescale has started to build up - so you may find yourself cleaning it more regularly.

Do glass kettles get less limescale?
Unfortunately, just like plastic and stainless steel kettles, glass kettles can experience a build-up of limescale and residue, especially in hard water areas.
One downside is that in a transparent glass design, any limescale build-up is visible - but this does serve as a visual reminder that it's time to descale your kettle.
While they’re likely to need descaling regularly, many glass kettles include filters that can help slow the build-up. You can also prevent limescale from occurring by only boiling the water you need.
What to look for in a glass kettle
If you’re considering adding a glass kettle to your kitchen, here are some features to consider:
Capacity - What is the maximum (and minimum) capacity of the kettle? If you’re regularly making drinks for your entire family or groups of friends, a kettle with a large 1.7-litre capacity should be high up on your wishlist, allowing you to serve a round of drinks without the need to regularly reboil. On the flip side, if you’re regularly preparing drinks for one when working from home, a kettle with a 250ml minimum capacity can prevent you from boiling more water than you need.
Filters - With a transparent design, any limescale build-up will be visible in your kettle. If you live in a hard water area where excess minerals can tarnish your appliances more quickly, you should consider a glass kettle with built-in or removable filters to prevent limescale build-up. Some glass kettles include stain-resistant glassware that can keep your kettle cleaner for longer, too.
360 base - Particularly important if you’re left-handed, how easy is it to access the kettle from all angles?
Variable temperature control - If you know your white teas from your oolong teas and are also partial to a strong cup of coffee in the morning, a glass kettle that allows you to set an exact temperature is a good idea. Not only will preset temperatures allow you to enjoy your drinks straight away, but it also preserves the flavours of different types of tea or coffee and keeps drinks tasting their best. An ideal feature for those on a quest for the perfect cup of tea.
Price - Good kettles range in price from £20 right up to £100. Think about what you need; if it's just a basic does-the-job kettle, a low price, no-frills option is your best bet. If you want fancy features or the ability to choose the desired temperature that's optimal for your brew, you can expect to pay £50 plus.
