EU 26 is where the mislabelling problem bites: a 2018 study of 1898 children's shoes found 86 percent measured shorter inside than their printed size, some by up to four sizes.
EU to UK conversion
EU to UK kids' sizes drift apart from about 17 numbers, then the UK column resets to 1 near a 220 mm foot, so EU 35.5 is UK 1 while EU 35 just below is UK 13.5. The reset makes the UK number briefly plunge even as the EU number and the foot both climb. A parent reading a UK size off an EU one has to know which side of that reset the child sits, or the shoe comes a whole cycle wrong.
At this size, EU to UK
One size up from EU 26, UK moves 0.5 to UK 8.5 while EU rises 1 to EU 27, so the two scales spread wider. Both EU 26 and UK 8 are whole numbers here, so nothing rounds. For EU 26, the UK column here runs UK 7.5, UK 8, UK 8.5, stepping a half size at a time.

Frequently Asked Questions Does EU 26 round up or down in UK? Buy by the inner length in millimetres, not the number on the box, and round toward the larger measured shoe; the label alone is unreliable at this age.
