The source of your water plays a major role in how it tastes. Across the UK, drinking water is supplied from a variety of sources, including rivers, reservoirs, lakes, and underground aquifers. As water travels through different types of rock and soil, it naturally absorbs minerals that can influence its flavour and overall character. Because the geology and water sources vary from region to region, the taste of tap water can differ noticeably between locations.
Does hard water affect the taste of tap water?
Yes, water hardness can influence how tap water tastes. Hard water contains higher levels of naturally occurring minerals, particularly calcium and magnesium, which can subtly affect its flavour. As a result, water supplied from chalk and limestone regions may taste different from water sourced from reservoirs, lakes, or other areas. However, taste is highly subjective, and there is no such thing as a universally “better” tasting water. Many people simply prefer the type of water they are most accustomed to drinking.
Why does tap water sometimes taste or smell of chlorine?
Chlorine plays an important role in the UK’s drinking water treatment process, helping to disinfect water and protect it from harmful bacteria as it travels through the distribution network. Although the amount added is carefully regulated to ensure safety and quality, some people are more sensitive to its taste or smell than others. In some cases, a chlorine taste or odour may be more noticeable following maintenance work on the local water network or in properties located close to a water treatment facility. While this can affect the drinking experience, it does not necessarily indicate a problem with the water supply, which continues to be monitored to meet strict quality standards.
Can a water filter improve the taste of tap water?
If your tap water is safe to drink but you prefer a fresher, cleaner taste, a drinking water filter may help. Activated carbon filters are commonly used to reduce chlorine tastes and odours, along with other substances that can affect the flavour of your water.
FAQs: The taste of tap water
A change in taste does not necessarily mean your water is unsafe. Natural minerals, treatment processes, seasonal changes, and household plumbing can all affect flavour. However, if you notice a sudden, strong, or unpleasant change, contact your water supplier for advice.
A metallic taste can occur when water has been sitting in pipes overnight. Running the cold tap for a short time will usually bring through fresh water. If the taste continues, it may be worth contacting your water supplier or a qualified plumber.
The best filter depends on what you want to improve. Carbon filters are commonly used to reduce chlorine tastes and odours, while reverse osmosis systems provide more comprehensive drinking water filtration. Choosing the right option starts with understanding your water and your priorities.
What should you do if you do not like the taste of your tap water?

Consider water filtration
If your water supply is safe but you prefer a fresher, cleaner taste, or peace of mind knowing exactly what you are putting into your body, a drinking water filter may help. Different systems are designed to improve taste, reduce chlorine, or provide more advanced filtration, depending on your needs.
