Finding drinks your kids will actually enjoy isn't always easy, especially when you're packing school lunches or heading out for the day. You'll want something that's convenient, affordable and tasty enough to get their seal of approval, ideally without added sugar.

That's where Radnor Splash comes in. Made with spring water and natural fruit flavourings, these sugar-free, low-calorie drinks come in a range of fruity flavours, including Apple & Raspberry and Orange & Passion Fruit.

We recruited Mumsnet parents of children aged seven to 12 to try Radnor Splash drinks at home. Half were allocated Apple & Raspberry and the other half Orange & Passion Fruit, with families sharing their experiences of the taste, packaging and how the drinks fitted into everyday routines.

The results were positive, with 88% of 91 testers saying they would recommend Radnor Splash, earning the drinks a coveted Mumsnet Rated badge.

Why do Mumsnet parents recommend Radnor Splash?

Taste was a standout feature during testing, with children enjoying the fruity flavours and refreshing quality of the drinks. Parents also appreciated the convenient carton size, particularly for packed lunches, after-school snacks and days out.

Testers particularly liked:

  • Fruity, refreshing flavours: Children generally enjoyed the taste of both Apple & Raspberry and Orange & Passion Fruit, with some commenting that they weren't overly sweet.

  • Convenient cartons: The 250ml cartons were easy to pack into bags and lunchboxes.

  • Sugar-free drinks: Parents appreciated having a sugar-free alternative to traditional juice drinks, although some expressed preferences around sweeteners.

  • Good value for money: At £1 for three cartons in major UK supermarkets, 92% of testers agreed Radnor Splash drinks offered good value for money.

  • Versatility: Families found the drinks worked well at lunchtime, after school and when out and about.

What did Mumsnet parents and their kids say about Radnor Splash?

Feedback from our testers was largely positive, with children enjoying the fruity, refreshing flavours of both Radnor Splash Apple & Raspberry and Orange & Passion Fruit. Parents also praised the convenient carton size, particularly for school lunches, after-school snacks and days out.

My child thought it was really delicious, very palatable and really refreshing.

- Mumsnet user AliBingo, Apple & Raspberry

I offered it with their after-school snack and they loved them, asking for more when they ran out! It slotted straight into our normal routine instead of water or squash.

- Mumsnet user archaeoptyrx, Apple & Raspberry

They thought it tasted lovely and was a great mix between a flavoured water and a squash. They thought it was the best out of all the Radnor flavours, which they have relentlessly drunk day after day at school, so that’s pretty high praise!

- Mumsnet user JaniceBattersby, Orange & Passion Fruit

Much nicer than similar drinks. I would never have chosen it and always gone for drinks I knew as a child. In future I'll look out for these products and choose other flavours to try.

- Mumsnet user Mabiscuit, Orange & Passion Fruit

Are Radnor Splash drinks good for school lunchboxes and days out?

Convenience was another recurring theme throughout the test.

According to the survey, 36% of parents were most likely to serve Radnor Splash after school, while 34% chose lunchtime. Families also reported taking the drinks to sports clubs, on day trips and for weekend activities.

The 250ml cartons were particularly popular with parents looking for drinks that could be easily packed into a bag without taking up too much space. 

A refreshing, tasty drink for children in colourful, appealing packaging. It's a convenient size for lunchboxes, days out or enjoying at home.

The cartons were also popular for their convenient size and straw-free design, although experiences with opening them varied. While some children enjoyed being able to drink directly from the carton, others found the foil tab a little tricky to open.

Are Radnor Splash drinks good value for money?

Value was another strong point in the survey, with 92% of testers agreeing Radnor Splash drinks offered good value for money.

With three 250ml cartons available from £1 in major UK supermarkets, parents appreciated having an affordable option for school lunches, after-school refreshments and family outings.

I would say they are inexpensive and handy for the rucksack.

- Mumsnet user DaisyDando

Several testers also expressed an interest in buying the drinks again, with some suggesting larger multipacks would be useful for families who regularly stock up.

Where can you buy Radnor Splash drinks?

Radnor Splash drinks are available in major UK supermarkets, with packs of three 250ml cartons priced at around £1.

The range includes fruity flavours such as Apple & Raspberry and Orange & Passion Fruit, both of which featured in our Mumsnet product test.
