There’s a reason they call it the Bank of Mum and Dad – in many families, it’s one of the most generous (and reliable) institutions around.

Whether it’s helping your child get on the property ladder, pay for university, or simply find their feet in adult life, financial support from parents and grandparents is now incredibly common. In fact, according to Savills, around half of first-time buyers receive help from family – and the average sum involved is a chunky £55,572.

That’s no small favour.

But while the intention is generous, it’s easy to misstep if you don’t plan carefully. From potential tax traps to pension headaches, there’s more to it than simply writing a cheque.

Here’s how to support your children (or grandchildren) without putting your own future on the line.

What “Helping” Actually Looks Like

Financial support can come in all shapes and sizes – and what’s right for one family might not suit another. It depends on what your kids need, and what you can afford.

The Big One: House Deposits

Helping with a house deposit is one of the most common roles the Bank of Mum and Dad plays.

• You can gift a lump sum – but be mindful of inheritance tax (IHT) rules.
• Alternatively, loaning the money (with proper documentation) adds clarity and avoids IHT issues if repayment is expected.
• Some mortgage products (like Barclays Family Springboard) allow you to use your savings as security, which are returned to you later. This can be a smart way to help without permanently parting with your cash.

Funding University or Education

Student loans don’t cover everything – and uni life isn’t cheap.

• You might cover tuition fees, living expenses, or both.
• A Junior ISA (JISA) is a great long-term option. You can save up to £9,000 a year, tax-free, until your child turns 18.

This helps ease their financial burden and sets them up with good saving habits.

Supporting Them as Adults

The first few years after education can be financially tight. Helping with rent, bills, or one-off expenses like a car or relocation costs can make a real difference.

You could:

• Offer a regular allowance to ease the transition into working life.
• Gift money for key costs like commuting or workwear.
• Sit down and help them budget – financial support doesn’t have to mean just handing over cash.

Just be careful: regular gifts might trigger IHT concerns if not planned properly.

Weddings, Cars, or Business Ventures

For big milestones, you can go further:

• A wedding gift of up to £5,000 for your child (or £2,500 for a grandchild) is completely IHT-free.
• Buying a car or supporting childcare costs can be a practical and meaningful way to help.
• Investing in a business idea? Great – but go in with eyes open. Business ventures come with risk, so get advice and document everything clearly.

The Tax Traps to Watch For

This is where things can get sticky. Helping your kids financially is a lovely thing to do – but it’s not always straightforward when HMRC is involved.

Inheritance Tax (IHT)

You can give away £3,000 a year IHT-free (that’s per person – so couples can give £6,000).

If you exceed that limit, the gift may still be tax-free if you live for 7 more years after giving it. Otherwise, it might be taxed as part of your estate.

Some other exemptions include:

• Wedding gifts – as mentioned above
• Gifts from regular income – if they don’t affect your lifestyle and are given regularly (this one’s often overlooked but incredibly useful)

Capital Gains Tax (CGT)

If you sell something – like a second home or shares – to fund your support, you may owe CGT.

• You can make £3,000 in gains each year tax-free (£6,000 for couples).
• After that, you’ll pay 18% (basic rate) or 24% (higher rate) on most assets.

Selling assets within ISAs or pensions? No CGT to worry about.

Pensions and the MPAA Trap

If you plan to use your pension pot to help your kids:

• You can take up to 25% tax-free (to a max of £268,275), but anything above that is taxed as income.
• Withdraw too much and you might trigger the Money Purchase Annual Allowance (MPAA), limiting what you can put back into your pension to just £10,000 a year. That’s a big deal if you’re still working and contributing.

How Much Is Too Much?

It’s easy to focus on helping your kids – but your own financial wellbeing matters just as much.

You’ll still need to fund your retirement, cover healthcare, and stay financially independent. Giving away too much too soon could backfire – especially if your own situation changes unexpectedly.

It’s all about balance.

Ask yourself:

• Can I afford this gift or loan without dipping into essential savings?
• Will I still have enough income in retirement?
• If the cost of living rises (again), will I regret parting with this money?

That’s where professional advice becomes invaluable.

Why a Financial Planner Can Be a Game-Changer

Acting as the Bank of Mum and Dad is generous – but it’s also a financial commitment that deserves just as much thought as any other big decision.

A good financial planner can:

• Run the numbers – how much can you really afford to give?
• Map out your retirement needs – so you’re not left short
• Structure gifts to reduce tax and avoid unintended consequences
• Advise on pensions, ISAs, and CGT – and how to use them smartly
• Help you plan for long-term care or other future costs

They’re there to help you be generous – without being reckless.

Final Thoughts

Helping your children or grandchildren financially can be one of the most rewarding things you do. It can change lives, ease pressure, and open doors that might otherwise stay closed.

But it’s not just about good intentions – it’s about smart planning.

Make sure your generosity doesn’t put your own future at risk. Understand the tax rules, weigh up the pros and cons of each option, and if you’re unsure – get advice.

Because while it’s lovely to be the Bank of Mum and Dad, you also want to make sure you don’t become its biggest borrower later on.

Support them well – and look after yourself, too.
