Four ISA types · one shared allowance · one headache

Your ISAs,finally simple.

Cash, stocks, lifetime, innovative-finance — four ISA types, one £20,000 allowance, and a maze of rules. OneISA runs them as a single account that manages itself: money goes to the right wrapper automatically, the allowance is tracked for you, transfers just happen. You pick a goal; we handle the rest — and it's built to be steadier than going all-in on stocks, so growing your money doesn't have to mean a rollercoaster.

Optional — two taps that genuinely shape what we build:

Where's most of your savings right now?
What's mainly kept you from sorting your ISAs out?

No spam, no sign-up rewards — just an early note when there's something to show. A concept, not a live product.

You're on the list.

Thank you — genuinely. If you answered the two questions, that's exactly the signal we needed to build the right thing.

Simple — and built to be steady

Simpler to use. Calmer to hold.

The reason most of us leave savings in cash is that the stock market feels like a gamble. OneISA is diversified and gets automatically calmer as your goal approaches — designed to ride steadier than all-in stocks, with a safe cash cushion you can always see. It's still investing, so your capital can fall as well as rise — but it's made to beat cash without the stomach-drop.

What we're trying to build
01

One account, not four

Money lands in the right ISA for your goal automatically, and the £20,000 allowance and tax-year clock are tracked for you — across all of it. You never pick a wrapper again.

02

Steadier by design

Diversified, and automatically calmer as your goal gets closer, with a visible cash cushion — so you're not exposed to the market's worst days. Lower volatility by design; still invested, so capital can fall.

03

No jargon, no juggling

Tell us your goal; we handle the wrappers, the mix, and the 30-day transfer maze behind the scenes. Tax-free in an ISA, in one account that runs itself.
