Bringing savings lump sum from offshore bank into UK

Dear HMRC, I became a UK tax resident in Sept 2021. I have some savings in an offshore branch of a UK bank (Lloyds International, which is based in Isle of Man). The savings have been generating some income because I have done some fixed term deposits. I have been declaring the interests I earned in my self assessment. My question is, when I eventually bring these savings into UK (say, in 5 years time), will I incur further tax if I've been paying tax for all the income generated (from interests) every year? Many thanks,
