More than 70% of people in the UK buy bottled water-even though tap water is available almost everywhere. Many believe bottled water is cleaner, safer, or healthier. But is that really true?
Let's take a closer look at how bottled and tap water differ, what's in them, and why using a filtered boiling water tap might actually be the most practical, eco-friendly, and health-conscious solution.
In 2021, people in the UK consumed around 10 million bottles of water every day-that's roughly 3.5 billion litres per year. Despite growing awareness of sustainability and reusable bottles, bottled water sales continue to rise.
This shows that many still distrust tap water or prefer the perceived purity of bottled options. However, this preference comes with environmental and economic costs.
| Statistic | Detail |
|---|---|
| Annual Bottles Used (UK) | 7.7 billion single-use plastic bottles |
| Recycling Rate | Only 9% recycled |
| Plastic Waste | 1,500 bottles discarded every second |
| Water to Make One 500ml Bottle | 5.3 litres |
| Plastic Waste per Person | 99 kg per year (UK average) |
Plastic production and disposal consume vast resources. Making one single-use bottle uses 10× more water than it holds. The result? Billions of bottles in landfill and oceans, harming marine life and ecosystems.
Mineral water comes from underground springs naturally rich in minerals such as calcium, magnesium, potassium, and fluoride.
Legally, it must be bottled directly at the source, remain uncontaminated, and not undergo chemical treatment. Popular UK brands like Evian and Volvic fall into this category.
While mineral water can offer health benefits, its "natural purity" doesn't always justify its high price-or its environmental footprint.
Spring water, like Highland Spring, also comes from underground sources but follows fewer regulations than mineral water. It may contain similar minerals, but composition varies and is not always disclosed.
Interestingly, many spring water sources are identical to public water supplies-meaning consumers may simply be paying for bottled tap water without chlorine.
UK tap water begins as rainfall that flows into rivers, lakes, reservoirs, or underground aquifers. Here's a quick overview:
| Region | Surface Water | Groundwater | Mixed Sources |
|---|---|---|---|
| England | 64% | 30% | 6% |
| Wales | 93% | 6% | <1% |
| Scotland | 80% | 10% | – |
Across the UK's 1,297 treatment plants, water goes through several purification stages:
| Stage | Process | Description |
|---|---|---|
| 1 | Screening | Removes leaves, sand, and debris |
| 2 | Flocculation | Chemicals bond small particles for easy removal |
| 3 | Filtration | Sand and carbon filters remove fine particles |
| 4 | Disinfection | Chlorine kills bacteria and prevents regrowth |
Chlorine ensures water stays safe through long pipe networks, though it can affect taste and smell.
Tap water naturally contains essential minerals like calcium and magnesium, which are good for health. However, some areas (especially the south of England) have hard water, leading to limescale buildup in kettles and appliances.
Old plumbing systems may still contain lead pipes, which can leach small amounts of metal into the water. That's why experts recommend filtering your tap water before drinking.
| Feature | Bottled Water | Tap Water | Filtered Boiling Water Tap |
|---|---|---|---|
| Safety | Strictly bottled, but may contain microplastics | Safe, regulated by DWI | Safest – filtered and freshly boiled |
| Taste | Often smoother | May taste of chlorine | Clean and fresh, chlorine-free |
| Cost | £0.50–£1 per bottle | < £0.01 per litre | One-time investment |
| Sustainability | High plastic waste | Eco-friendly | Reusable, sustainable |
| Convenience | Portable | Readily available | Instant filtered hot or cold water |
- Tap Water: Safe for up to 24 hours when stored in a sealed glass bottle in the fridge.
- Bottled Water: Unopened bottles last up to 2 years, but plastic can leach chemicals over time.
- After Opening: Bottled or stored water should be consumed within hours to avoid bacterial growth.
Studies reveal bottled water can contain hundreds of microplastic particles per litre. In fact, the average person may ingest the equivalent of a credit card's worth of plastic every week.
Researchers have even found microplastics in human blood and organs, raising serious long-term health concerns.
Yes-especially when properly filtered. Tap water is heavily regulated, cheaper, and much more sustainable. However, its chlorine content and local pipe conditions can affect taste and quality.
That's why water authorities and health experts recommend using a water filter for the best balance of safety, taste, and convenience.
Filtering your tap water removes unwanted chlorine, heavy metals, and sediments while keeping beneficial minerals intact. It's an affordable, eco-friendly alternative to bottled water-without plastic waste or recurring costs.
A filtered boiling water tap combines advanced filtration with instant hot, cold, or ambient water on demand. Designed for modern homes and offices, it offers:
✅ Multi-layer filtration – removes chlorine, sediment, and microplastics
✅ Instant boiling water – perfect for tea, coffee, or cooking
✅ Eco-friendly efficiency – reduces energy and plastic waste
✅ Elegant design – seamless integration under your sink

While bottled water might seem convenient, it's costly for both your wallet and the planet. Tap water in the UK is safe, but filtering it enhances purity, taste, and confidence.
If you want pure, great-tasting water without plastic waste, a filtered boiling water tap is the best of both worlds-safe like bottled, sustainable like tap.
1. Is bottled water safer than tap water?
Not necessarily. Tap water is regulated and tested daily, while bottled water can contain microplastics.
2. Why does tap water taste like chlorine?
Chlorine keeps it safe from bacteria. A filtered boiling water tap removes chlorine taste completely.
3. How can I make my tap water taste better?
Use a filter system with activated carbon to eliminate odors and impurities.
4. Is it okay to drink stored tap water?
Yes, if stored in a sealed glass bottle in the fridge for less than 24 hours.
5. Are filtered boiling water taps worth it?
Absolutely. They provide instant, filtered, energy-efficient water-hot or cold-while reducing plastic use.
