Tax query on investment bond

OK, found the answer myself. Total income with no averaging applies to Age Allowance according to this article.

Certain allowances, such as Age Allowance for those over 65 or Children’s Tax Credit depend on overall income. As the total gain (without averaging) is treated as part of your income for that year, these allowances may be reduced or eliminated by the gain.

Thanks to everyone who tried to assist answering my ramblings!
