Can I just check, if notional tax has not been deducted, will I be entitled to £5k annual allowance on this tax year?

I invested £23k in 2012 and I have made no withdrawals or alterations to the bond. Am I correct in assuming £10k of the chargeable event value will not be subject to tax and the £3,300 will be at basic rate of tax?

I have just cashed in my Bond at a value of £37,000 and have been advised of a chargeable event of £13,300. My total earnings for this financial year will be £20,000. How much tax will I be liable for on this chargeable event?
