For grandparents · UK launch 2026

The most meaningful thing you can do
for your grandchildren isn't a birthday gift.

It's starting an investment the day they're born
and watching it compound for the next 18 years.

Enter your grandchild's details below and see exactly what a regular contribution from you — even a small one — could build by the time they're an adult.

Why it matters

Most grandparents give cash gifts.
Almost none invest them.

The difference isn't the intention — it's the outcome. £50 given as a birthday gift is spent within weeks. £50 invested in a Junior ISA at birth becomes something entirely different 18 years later. Compounding doesn't care about the amount. It cares about the time.

📈
Compounding works silently
Every pound you invest earns returns, and those returns earn their own returns. Over 18 years the effect is dramatic — even on small regular amounts.
🔒
It's ringfenced for their future
Money in a Junior ISA can't be touched until your grandchild turns 18. It stays invested and keeps growing — it won't be spent on something that doesn't matter.
👨‍👩‍👧‍👦
The whole family compounds together
Amplifi is designed for the whole family. Parents, grandparents, godparents — everyone contributes to one account. Every contribution compounds alongside yours.
The numbers

£50 a month. Two completely different outcomes.

The same amount. The same grandparent. The only difference is what happens to the money.

Given as cash gifts
£10,800
£50 a month for 18 years. Well-intentioned, gratefully received, and mostly spent on things no one can remember.
Invested in a Junior ISA
£26,734
The same £50 a month, compounding at 8% a year inside a tax-free wrapper. A deposit. A safety net. A real head start in life.

Projection assumes 8% annual return. Capital at risk. Past performance is not a guide to future returns.

How Amplifi works

Simple to contribute.
No paperwork. No confusion.

Amplifi is designed so that grandparents can contribute directly to a grandchild's Junior ISA without needing to set anything up themselves — the parent opens the account, and you get a simple way to pay in.

1
The parent opens the Junior ISA
A parent or guardian opens the Amplifi Spark account for the child. This can be done from birth — or even before, for a baby who's on the way.
2
You're invited to the family gifting network
The parent adds you to the account's family network. You receive a simple link or invitation — no need to create a full account or manage anything yourself.
3
Set up a regular contribution — or give one-off gifts
You can set a monthly standing order, or contribute one-off amounts — birthdays, Christmas, whenever suits you. Even irregular contributions compound over time.
4
Watch it grow
Your contributions sit alongside the parents', all compounding tax-free inside the Junior ISA. You can see the fund grow over time — and know exactly what you're building for them.
Worth knowing

Regular gifts to grandchildren can also reduce your estate for inheritance tax purposes.

Gifts made out of regular income — such as monthly contributions to a grandchild's Junior ISA — can qualify for inheritance tax exemption under HMRC's "normal expenditure out of income" rules. This means the money leaves your estate immediately, without using your annual gift allowance. It's worth discussing with a financial adviser to understand how it applies to your situation.

Annual gift allowance
You can give up to £3,000 per year as outright gifts, free from IHT. Unused allowance can be carried forward one year. This is separate from the regular gifts rule.
Normal expenditure out of income
Regular gifts from surplus income — like a monthly ISA contribution — can fall outside your estate immediately. There's no upper limit, as long as the gifts are regular and don't affect your standard of living.
