Hard water is a common issue for many homes across the UK, but some areas seem to suffer more than others. Kent, for example, has long been known for its hard water, and many residents wonder if it really is the worst place for it. But how does Kent compare to other regions in the UK when it comes to hard water? And is it the top contender, or are there other areas that experience harder water?
In this blog, we’ll compare the hardness of water in Kent to other parts of the UK and break down what that means for your home. If you live in Kent and are considering solutions for hard water, or if you’re simply curious about how your region stacks up, this blog is for you.
What Is Hard Water?
Before we dive into the specifics, let’s first define what hard water is. Hard water is water that contains a high concentration of minerals, primarily calcium and magnesium. These minerals can cause a range of problems in the home, including limescale build-up, reduced efficiency in appliances, and dry skin and hair. Hard water is typically measured in “hardness” units, where higher numbers indicate harder water.

Can You Taste Hard Water?
Yes, you can taste hard water, although it may not always be obvious. The minerals in hard water, primarily calcium and magnesium, can give the water a slightly metallic or mineral-like taste. However, this taste is often subtle, and many people don’t notice it unless they compare it to soft water. In areas with extremely hard water, the taste may be more noticeable, especially when the water is used for drinking or cooking. Some people even find that hard water affects the flavor of tea and coffee, as the minerals can interact with the compounds in the drinks.
Can You Feel Hard Water?
Yes, you can also feel hard water, especially when it comes into contact with your skin or hair. Hard water can leave a film or residue on your skin after a shower, which can make it feel dry or slippery. This is because the minerals in the water interact with soap, creating soap scum that doesn’t rinse away as easily as it would in soft water. Over time, this can lead to dry, irritated skin and make it harder to get a good lather from your soap or shampoo. For your hair, hard water can leave it feeling dull, dry, or lifeless, as the minerals can build up and cause residue to form on the strands.
The Hard Water Situation in Kent

Kent is often cited as one of the areas in the UK with the hardest water. This is due to the geology of the region, which contains large amounts of limestone and chalk. When water from the region flows through these materials, it picks up minerals like calcium and magnesium, resulting in high levels of hardness.
According to water hardness data, Kent’s water hardness ranges between 250 and 350 ppm (parts per million), which is considered very hard. This means that residents of Kent often face significant challenges, such as limescale build-up in appliances, poor water quality, and higher energy bills due to reduced appliance efficiency.
However, while Kent does have hard water, it may not be the hardest in the UK. Let’s take a look at how other regions compare.
How Does Kent Compare to Other UK Regions?
1. London
London is often considered to have very hard water, similar to Kent. In fact, many areas of London fall into the “very hard” category, with hardness levels ranging from 250 to 400 ppm. The hardness in London is largely due to the region’s underlying geology, which is rich in chalk and limestone, much like Kent.
However, some areas of London have slightly softer water due to the presence of reservoirs that dilute the mineral content. Still, for most residents of London, hard water is a common issue that requires solutions like water softeners to reduce the impact of limescale build-up.
2. South East England
The South East, which includes Kent, has some of the hardest water in the UK. However, other parts of this region, such as Sussex and Surrey, also experience very hard water, similar to Kent. This is particularly true for areas that source their water from underground aquifers, which tend to have high mineral content.
While Kent does stand out in the South East, it’s not the only area with significant hard water issues. Many residents in the surrounding counties also deal with similar problems.
3. The Midlands
In contrast to Kent, the Midlands tends to have a more varied level of water hardness. Areas like Birmingham and Nottingham have moderately hard water, with hardness levels ranging from 150 to 250 ppm. This is still considered hard, but not as severe as Kent’s very hard water. The mineral content in the Midlands is generally lower, which means less frequent limescale build-up and fewer appliance issues.
However, some parts of the Midlands, particularly near certain river sources, can experience hard water similar to Kent, especially in rural areas.
4. North of England
The North of England, including cities like Manchester and Leeds, typically experiences soft to moderately hard water, with hardness levels ranging from 100 to 200 ppm. The further north you go, the softer the water tends to be. In many areas, natural filtration through sandstone and clay reduces the levels of calcium and magnesium in the water, resulting in softer water compared to the South.
However, some areas in the North, particularly near industrial zones, may experience higher hardness due to water being sourced from lakes and rivers with higher mineral content.
5. Scotland
Scotland is known for having some of the softest water in the UK. Areas like Edinburgh and Glasgow have water hardness levels that typically fall between 20 and 100 ppm. This is due to the geology of Scotland, where water is primarily sourced from lochs and rivers with very low mineral content.
For residents in Scotland, hard water is rarely a concern. In fact, many Scots enjoy the benefits of softer water, such as reduced limescale build-up and fewer issues with appliances.
Is Kent Really the Worst for Hard Water?
While Kent is definitely among the worst places for hard water in the UK, it’s not the absolute hardest region. Areas in London and some parts of the South East experience similar or even slightly higher levels of water hardness.

However, Kent’s reputation for hard water is well-deserved due to its high concentrations of calcium and magnesium, which cause frequent limescale problems and appliance inefficiencies.
What Can You Do About Hard Water in Kent?
If you live in Kent or any other region with hard water, there are several solutions to help manage its effects:
- Install a Water Softener: A water softener can help reduce the mineral content in your water, preventing limescale build-up and protecting your appliances.
- Regularly Clean Appliances: Descaling your kettle, dishwasher, and other appliances can help remove existing limescale deposits.
- Use Limescale Removers: For stubborn deposits, consider using limescale removers that are specifically designed to tackle mineral build-up.
If you’re tired of dealing with the effects of hard water, a water softener is the best long-term solution. Aquasoft offers a variety of high-quality water softening systems that can help protect your home from hard water damage and improve the quality of your water. Get in touch today to find out more.
