Britain’s Water Confidence Divide: Why Where You Live Could Be Affecting How Much Water You Drink

 

Britain is home to some of the safest drinking water in the world, yet new research suggests that many people still lack confidence in what comes out of their tap. 

 

To help people better understand the water in their local area, Our Taap has launched its new Water Confidence Index, allowing households to enter their postcode and view local satisfaction scores alongside information about water hardness, chlorine levels and how these factors may influence taste. 

 

The company hopes the tool will help explain why tap water can taste so different from one postcode to the next, while encouraging more people to feel confident drinking water straight from the tap.

 

This follows a new nationally representative study from the home water filtration brand which has revealed significant regional differences in tap water satisfaction across the UK, with Edinburgh ranking highest in the company’s new Water Confidence Index (9.18 out of 10), while the London borough of Bexley ranked lowest (4.87 out of 10).

 

The findings suggest that, although water quality remains consistently safe, the experience of drinking tap water varies considerably depending on where people live.

 

The research, which surveyed 2,000 UK adults, found that only 40% regularly drink tap water without hesitation, while almost half admit they have little or no understanding of what is actually in their local water supply.

 

Instead, many households have developed everyday habits to make their tap water more appealing. Around 85% of respondents said they “work around” their tap water in some way, whether by letting the tap run before filling a glass, chilling water in the fridge, or adding squash to improve the taste.

 

The issue becomes even more noticeable during warmer weather. Nearly one in three people (30%) said they drink less tap water when it comes out warm, while the same proportion said they feel more dehydrated because they dislike the taste of warm tap water.

 

The research highlights a clear geographical divide in satisfaction.

 

Scotland and Northern Ireland dominate the top of the rankings, with Edinburgh, Derry, Dundee and Glasgow all appearing in the top five locations nationally. By contrast, five London boroughs feature among the ten lowest-scoring areas, including Bexley, Barking and Dagenham, Hammersmith and Fulham, Southwark and Lambeth.

 

Perhaps most striking is the contrast within London itself. Westminster ranked second nationally with a score of 9.05, despite being only a short distance from Bexley, which finished at the bottom of the rankings.

 

To understand these differences, Our Taap combined consumer survey findings with postcode-level data on water hardness and chlorine levels.

 

The analysis found that lower satisfaction scores generally coincided with higher levels of water hardness and chlorine, both of which can noticeably affect taste.

 

In Bath, 93% of residents said limescale or hard water is a daily issue, while in Carlisle, one-third described their tap water as smelling of chlorine. Meanwhile, Camden recorded the highest proportion of people who reported taste as a problem, with more than half (56%) saying they were dissatisfied with the flavour of their local tap water.

 

Across the UK, almost one in five people (18%) said their water tastes or smells of chlorine, while more than a third (37%) said they know they have hard water but don’t feel they have an effective solution.

 

Dr Rupy Aujla, GMC-registered doctor, nutritionist and founder of The Doctor’s Kitchen, believes taste plays an important role in helping people stay hydrated.

 

He said: “While drinking enough water is one of the simplest ways to support our health, building good hydration habits isn’t always easy. Taste is a real, practical barrier to hydration; if water doesn’t taste good, people simply drink less of it, or they reach for something else.

 

“In summer, when hydration needs can vary depending on climate and activity level, making water more enjoyable to drink could help people build healthier habits that they’ll actually stick to.”

 

Genevieve Upton, Our Taap’s Filtration Expert, says: “Tap water can be perfectly safe to drink but still not taste the way people want it to. Chlorine, hardness and limescale can all affect the experience in the glass, and those taste cues can become especially noticeable when water comes out warm. Our Taap is designed to change that experience by delivering filtered, chilled water on demand, reducing common causes of off-tastes while keeping the minerals that give water balance. It means households can get genuinely refreshing water straight from their own tap, without needing to keep refilling jugs or waiting for bottles to chill.”

 

Dr Bill Simpson, Our Taap’s Taste Expert, says: “If water tastes chlorinated, metallic or hard, it stops feeling refreshing and in hot weather that matters even more. Cold water makes these off-putting flavours and tastes less noticeable. And low temperatures provide important sensory cues: clean, crisp, cooling and easy to drink. When water tastes good, people are much more likely to keep going back for another glass.”
