Our verdict

Tried and recommended by Mumsnet Senior Content Editor, Rebecca: read her review of the Russell Hobbs Purity Glass Brita Kettle.

If your kettle furs up faster than you can say “who’s put the kettle on?”, this one starts to look less like a fancy upgrade and more like damage limitation. In a hard water home, the built-in Brita filter genuinely makes a difference - after nearly a month of daily use, our editor Rebecca hadn’t seen any limescale forming in the base, and drinks tasted cleaner too.

It’s also a nice-looking bit of kit. The glass and stainless steel feel more premium than the plastic version, the blue light is a handy “yep, it’s on” visual cue, and once it’s filled it boils quickly (a cup in under a minute) and fairly quietly.

But you do pay for that filtration in time and faff. Because the filter chamber only holds about two cups, filling to max means doing it in two stages – pour, wait, then pour again – and there’s a bit of filter prep before first use.

The other biggie is ongoing cost: the indicator was down to 50% after three weeks, so you’re realistically replacing the cartridge about once a month. If you already use a Brita jug, you might not need this at all. But if hard water is your nemesis, and you’re happy to trade capacity and convenience for less limescale and less descaling, it’s a solid choice.

Best budget glass kettle

ASDA Iridescent Glass Fast Boil Kettle 1.7L

Check price at ASDA Check price at George

What we like

Budget-friendly price
Large full capacity
Fast boil
Stylish iridescent design that illuminates during the boil
Clearly marked water scale

What we don't like

Some reviewers found it noisy during the boil
Iridescent design isn’t completely transparent

Key specs

Our verdict

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 with variable temperature

Cookworks Variable Temperature Glass Kettle

Check price at Argos

What we like

Choice of four temperature settings
Sleek design
Blue light illumination on boiling
Removable and washable limescale filter
Boil-dry protection
Keep warm feature

What we don't like

Pours slowly due to filter in the spout
Two cups minimum volume

Key specs

Our verdict

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 we like

Soft top lid to reduce splashing
Ergonomic handle
Compact design with a four-cup capacity
Multi-directional base

Small size - less suited to preparing drinks for larger groups

What Mumsnet users say

Dbank · Recommended product

[...] Bit over budget, but really nice to use and doesn't fur up, at least with a normal water softener.

See Post

Our verdict

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.

Best jug glass kettle

LOGIK L17GK22 Jug Kettle

Check price at Currys

What we like

360-degree base
Illuminates blue during the boil
Affordable price point
Limescale filter in the spout

What we don't like

The minimum volume is more than one cup

Key specs

Our verdict

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.
