Nobody sits you down when you arrive in the UK and explains how money works here. You figure out the NHS, the council tax, the oyster card. But the stuff that actually builds long-term financial security? That tends to get missed.
ISA which stands for Individual Savings Account, is one of those things. In simple terms, it is a savings or investment account where the government cannot touch what you earn inside it. No tax on interest. No tax on investment growth. Every year, you get an allowance of up to £20,000 to put in, and whatever that money makes is entirely yours.
Most people I speak to either have never heard of it, or assumed it was not for them. It is. Whether you have been here two years or ten, whether you are saving a little each month or have a lump sum sitting in a current account doing nothing, an ISA is worth understanding.
The rules also just changed. In June 2026, the government announced that from April 2027, the amount you can save in a Cash ISA will drop from £20,000 to £12,000 for anyone under 65. This tax year is the last window to use the full allowance in cash.
I put together a free beginner’s guide that walks through all of it, without the jargon. It covers every type of ISA, the 2027 changes, and how to open one.
