I have a three year National Savings Bond that matures Feb 2026. In February 2024 I received interest that was titled 'Interest Capitalisation'. Do I declare this on the 23 - 24 tax return, or wait until the bond matures and declare all interest then as one figure?

I have a three year National Savings Bond that matures 10th February 2026. On the 1st anniversary ie 10th February 2024 the following was declared by NS&I: 'Interest Capitalisation = £510'. Do I declare this on my 23-24 tax return, or do I wait until the bond matures in Feb. 26 and then declare total interest earned then?
