Lightest Mineral Water in the UK: Top 5 Compared
Among the mineral waters available in the UK in the h2oMatch database, these have the lowest fixed residue values.
Light mineral waters are those with a low total mineral content, measured as fixed residue, which gives them a clean, neutral taste.
The lightest mineral waters in the UK — top 5 by fixed residue.
The following waters are ranked by their fixed residue, from lowest to highest.
| Water | Fixed residue (mg/L) | Sodium (mg/L) |
|---|---|---|
| VOSS STILL | 40 | 3 |
| Deeside | 60 | 6 |
| Aqua Pura | 110 | 11 |
| Volvic | 130 | 12 |
| Acqua Panna | 143 | 7 |
VOSS (40 mg/L) is the only water below 50 mg/L, with Deeside close behind at 60 mg/L. The other three range from 110 to 143 mg/L, roughly two to three times higher.

The UK's geological diversity means consumers can find everything from very light Scottish spring waters to more mineral-rich options from England's chalk and limestone regions.

FAQ
What is the lightest mineral water available in the UK?
VOSS is the lightest mineral water in the h2oMatch UK database, with a fixed residue of 40 mg/L.
What does 'very low mineral content' mean?
A water is classified as having ‘very low mineral content’ when its fixed residue, or total dissolved solids, does not exceed 50 mg/L. Waters with 50 to 500 mg/L are classified as having ‘low mineral content’.
What is the lightest British-sourced water?
Deeside, sourced from Scotland, is the lightest British water in the ranking with 60 mg/L of fixed residue, placing it just above the ‘very low mineral content’ threshold.
Is fixed residue the same thing as sodium?
No, fixed residue measures all dissolved minerals, while sodium is only one of them. For instance, while Aqua Pura has more fixed residue than Deeside (110 vs 60 mg/L) and also more sodium (11 vs 6 mg/L), the two values do not always move together.
What is light water best suited for?
Their low mineral content gives these waters a neutral, soft taste. This makes them popular for preparing tea and coffee, as they interfere less with delicate aromas and leave less limescale when heated.
All values are based on official mineral water labels and the h2oMatch database.
