No idea where you got your 24% from. If you become a resident you will pay income tax as any Spanish citizen. You get a tax free allowance due to your age, marriage status, income etc and then pay 19% up to a certain amount, 21% above that and rising in increments just like it does in UK. The only 24% bit is that non EU residents pay 24% of their deemed property value in non resident tax as opposed to EU citizens who only pay 19%. Residents are treated the same as citizens and there is no 24% blanket tax on anything.
You will pay income tax on all world wide income less crown pensions such as Armed Forces, civil service and many others but your state pension will be included for tax purposes.
You will also advise HMRC you are now resident in Spain and you will not pay income tax in UK except on those crown pensions I mentioned. You can only be taxed in one country under the dual tax agreement and that country will be Spain.
You will also pay an annual council tax (called IBI) which, for me, works out about 250 euro a year instead of 220 pounds a month in UK.
Of course, there are other taxes but someone has misadvised you on paying 24% tax on all your income.
