The Bank of Mum and Dad Is Overdrawn

In a single year, families in Britain handed over £9.2bn to help each other buy homes. It has quietly become one of the biggest forces deciding who can buy a home at all. That money helped fund around 335,000 home purchases, at an average of £27,400 each.

Money on this scale is never free. Someone always carries the cost. Just not always the person you would expect.

We call it the Bank of Mum and Dad, and the name sounds gentle. A bit of help. A leg up. Money that was lying around anyway. But £9.2bn is not a bit of help. It is one of the quiet foundations of how Britain buys homes now, not a backstop for emergencies but a fixture. And it is still growing: Legal and General expect family help to keep climbing toward £11bn a year.

It got this big because the maths stopped working. Deposits grew faster than wages, and saving one from scratch became a project that ran for years. So the money had to come from somewhere, and for hundreds of thousands of buyers, somewhere means a parent. For a whole generation, a parent's help has stopped being a lucky extra. It has become the difference between owning a home and not.

Where nine billion pounds actually comes from

Every bank's money comes from somewhere. So where does this come from? It comes out of the older generation's own savings.

Legal and General asked people over 55 where they found the money they gave. 48% used cash savings, the rainy-day fund meant for the boiler, the car, the thing that goes wrong without warning. 40% used ISAs and investments, money that was quietly working for their own future. Around one in eight took a lump sum out of their pension, money set aside to pay them later in life. And nearly a fifth, almost 20%, took it out of the home itself: by downsizing, by borrowing against the house through equity release, or by remortgaging in their sixties.

None of that is loose change. It is the retirement pot, the safety net, and the family home. And here is the part the friendly name hides. The Bank of Mum and Dad has no deposits of its own. A real bank lends out other people's money. This one lends out its own. Nearly every pound it gives is a pound taken out of the giver's own future.

What it costs the people giving

Quite a lot, as it turns out. Of the family members who gave money, nearly half, 49%, said they felt less secure about their own finances afterwards. Around one in nine said it had lowered their standard of living.

In a separate study, Standard Life asked parents directly, and the picture sharpened. Three in five are handing money to grown-up children. Three quarters of them say it has reached their own finances, not their children's. And the cost tends to land in the one place that is hardest to rebuild: one in seven now expect to retire later than they planned, and the same number expect a smaller retirement, leaning harder on the state pension.

The cost does not arrive on the day of the gift. It arrives years later, in a smaller retirement, and by then it is very hard to undo.

This is the quiet trap inside generosity. In the moment, the help feels affordable: a transfer, a signature, a child finally on the ladder. A pension is not like a current account. You cannot quietly top it back up at 63. The years it needed to grow have already gone.

The bank that is already overdrawn

And all of this assumes the parents had it spare to begin with. Many did not. The generation playing the bank is not debt-free. According to SunLife, 45% of over-50s are still carrying debt of their own, averaging around £23,800, and higher, at around £33,600, for those who own their homes. This is the generation everyone assumes can afford to help. More than one in ten are even considering equity release to clear debts of their own.

So picture what is actually happening. The same home equity a parent might hand to a child for a deposit is, for many, already promised to debt they carry themselves. This is what overdrawn really means: money given out by people who, in their own lives, are still in the red.

And Standard Life's research found most of it never comes back. More than half of the parents who give money expect nothing in return. That sounds generous, and it is. But it also means most of this money has no terms. No paperwork. No date. No protection. If the parent later needs it, there is no clean way to ask for it back. If a relationship breaks down, no one can say for certain whose money it was.

The pressure is structural, not a family failing

None of this is an argument against helping your children, and it is not a charge against young people who took the money. For many of them, the alternative was being shut out of a home for years. The pressure here is not a family failing. It is structural. A housing market made family wealth a condition of owning a home, then quietly passed the cost to whichever generation could absorb it. And that generation is running out of room.

So strip the sentiment out of it. The Bank of Mum and Dad is £9.2bn of real money, mostly given rather than lent, drawn from the savings, the pensions and the homes of people who are often already carrying their own debt. The warmth is real. The love behind it is real. But so is the cost. It just arrives later, and quieter, on the giver's side of the ledger. Two generations, paying for the same problem from opposite ends.

One realistic move

Helping family is not the mistake. It is one of the more decent things people do with money. The part worth slowing down for is the part that stays hidden: knowing what the help takes out of your own future, before you give it.

If you are thinking about helping someone you love, there is one free place to start. MoneyHelper is the government-backed guidance service, and it has nothing to sell you. Before you give, it helps you ask three honest questions. Can you actually afford this? Is it a gift, or a loan? And if it is a loan, is it written down? Not to stop you helping, but to help you do it with your eyes open, because the kindest version of this is the one you can afford to give.
