Why Does UK Tap Water Taste Like Chlorine?
UK water companies add chlorine to kill harmful bacteria - it's what makes our tap water safe to drink. The legal limit is 0.5mg/L, but even at much lower concentrations, many people can detect the taste and smell.
Why Some Areas Taste Worse
Homes near water treatment plants often have stronger chlorine taste because the chemical hasn't had time to dissipate. Areas at the end of distribution networks typically have lower chlorine levels.
While chlorine at UK levels is considered safe, it can react with organic matter to form disinfection byproducts (DBPs) like trihalomethanes. These are linked to health concerns with long-term exposure. A good carbon filter removes both the chlorine AND these byproducts.

Frequently Asked Questions
Why does UK tap water taste like chlorine?
UK water companies add chlorine to kill bacteria and make water safe to drink. The legal limit is 0.5mg/L, but even at lower levels many people can taste it. Chlorine taste is strongest in areas near water treatment plants.
Do all water filters remove chlorine taste?
Most carbon-based filters effectively remove chlorine taste and smell. Look for NSF 42 certification which specifically tests for chlorine reduction. Basic sediment filters do NOT remove chlorine - you need activated carbon.
How long does it take for a filter to remove chlorine taste?
The effect is immediate. As soon as water passes through an activated carbon filter, 95-99% of chlorine is removed. You'll notice the difference with your first glass of filtered water.
Is chlorine in tap water harmful?
At UK legal levels (up to 0.5mg/L), chlorine is considered safe. However, chlorine can react with organic matter to form disinfection byproducts (DBPs) like trihalomethanes, which are linked to health concerns with long-term exposure. Filtering removes both chlorine and many DBPs.
