Saving for grandchildren is a top priority for many of us.
We love to dote on them, buy them presents and teach them our worldly wisdom. We want our grandchildren to be the happiest they can be, and make sure they have a bright and stable future.
For some of us, that means looking to give them a bit of financial stability if we can.
With childcare, nursery and education costs so high, many parents struggle financially. It's understandable that grandparents want to help in any way they can.
Saving for grandchildren: things to consider
Of course, cash slipped into a birthday card or pocket is a welcome gift. But there are other ways to put your spare cash towards something that might have a more lasting effect.
There are a few things to bear in mind first. While we might want to help as much as we can, many of us have to consider our own finances first. It's important to make sure any aid is within our means.
Don't wait until the last minute
Saving for the grandkids is no different to saving for a car or house renovation. The earlier you start to put money aside, the more financially stable you'll be.
If you think you'll be saving for a long time, it might be worth looking at the options outlined here.
Consider tax-efficient options
Giving lump sums can incur taxes. So look into your options before gifting money to your grandchildren.
Inheritance tax and other taxation issues can take the joy out of monetary gift giving. Despite this, understanding the rules makes life much easier.

Think about when your grandchild will need the money
The type of help that younger and older grandchildren will appreciate is probably very different.
Costs like school fees or extracurricular activities are very different from university fees or a house deposit. And the way you might want to save for these will be different.
Whatever your aim, here are some options to consider that might help you put aside more than just a few pennies.
Remember, always seek financial advice before you make any decision.
5 ways to save for your grandchildren
1. Set up a children's savings account
If you'd like to set up a savings account in your grandchild's name, you'll need legal documentation such as their birth certificate.
A child's savings account is taxed the same way as an adult's. But most children have an income below the personal allowance threshold (£12,570 for 2026/27[1]). This means the savings are usually tax‑free, although different rules can apply depending on where the money comes from and how much interest it earns.
You can normally manage these accounts how you wish, putting in as much or as little as you like. But all banks and accounts will be different, and have different terms and conditions. So make sure you do your research and choose the one that works best for you.
2. Pay into a junior ISA
Some grandparents choose a Junior ISA as a way of setting money aside for their grandchildren’s future. The money can't be accessed until their 18th birthday – and only they can access it.
Only a parent or guardian can set up a junior ISA for their children. But other members of the family can pay into the account. This makes them a good option for grandparents.
Depending on the tax year, there'll be a limit on how much you can pay into the account. Despite this, how you contribute is normally quite flexible.
In 2026/27, the allowance is £9,000[2]. (Those with a Child Trust Fund (CTF) may be ineligible or may have to transfer their CTF to a junior ISA[2]).
If you're looking to put in a little each month, you can just set up a direct debit. This makes it easier to work out exactly how much you'll be contributing for the year.
A junior ISA is also a great way to show children the benefits of ongoing investment.
Once they turn 18, their junior ISA will automatically roll into an adult ISA[3]. They'll then have total control of the money – so they may need a little advice from their wise grandparent on how to spend or keep saving it!
3. Set up a pension for your grandchild
This may seem like a far-off concept, especially if your grandchild is very young. But as we all know, time flies – and before they know it, they'll be planning for retirement.
You can start a self-invested personal pension (SIPP) from the moment a child is born and contribute up to £3,600 to it each tax year. The contribution limit of £3,600 includes tax relief paid at 20%, which means you can contribute £2,880 each year, with £720 being paid automatically by the government.
Your grandchild will gain access to it when they turn 55 (although this is rising to age 57 in 2028)[4]. Over time, a small monthly amount can result in a large sum for them, which could really help them out later in life.
4. Pay your grandchild's house deposit
If you'd like to financially help your grandchildren in one fell swoop, paying their property deposit could be the way to go.
The bigger the deposit paid, the lower the mortgage payment your grandchild will pay. So gifting money towards a house deposit should mean lower monthly repayments. This could be a huge help for them in the future.
5. Using allowances to give tax free gifts
Annual exemption
If you simply want to gift your grandchildren some money each year, you can give up to £3,000 without paying tax[5].
Small gift allowance
You can give small tax-free cash gifts of up to £250 to as many people as you like during the tax year, as long as you have not used another allowance on the same person[6].
Gifts for weddings or civil partnerships
You can also give a tax free gift of up to £2,500 to a grandchild or great-grandchild, who is getting married or starting a civil partnership.[7]
However you wish to help your grandchildren financially, they're sure to be grateful. Just remember to seek professional financial advice before you make any decisions.
