Underspending

The millionaire who won't put the heating on

Underspending gets almost no attention because it looks like virtue. For people who have spent a lifetime being careful, it is often the thing costing them most.

Almost everything written about money assumes your problem is spending too much. For a substantial number of people — often the ones who did everything right — the problem runs the other way, and nobody ever mentions it because it looks like good behaviour.

We see couples in their seventies with several million and no debt, living entirely on the state pension because they will not touch the investments. Retired people who won't put the heating on in February. People who have not taken a proper holiday in a decade, not from lack of means but because spending the money feels physically wrong.

It isn't meanness

It is almost always fear, laid down early and never revisited. Someone watched a parent get caught out, or grew up where money genuinely ran out, and concluded that the only safe amount is more. That belief did its job for forty years — it is exactly why they have the money. It simply never received the message that the danger had passed.

Worth knowingBeing careful with money is the healthiest pattern of the four money types. People who score high on it carry less debt and save more, consistently. The bill is not financial. It is the life not lived while the money sat there.

The bill arrives anyway — it just arrives later

The quiet assumption underneath a lifetime of not spending is that the money is being kept safe. Often it is being kept in the one place where somebody else eventually takes 40% of it. Underspending does not avoid a cost. It defers the cost and changes who pays it.

Worked example — illustrative figuresA widow of 78 owns a house worth £600,000 and holds £600,000 in cash and investments. She will leave everything to her two children. She lives on the State Pension, has not been abroad since 2014, and keeps the heating off until December.

Her allowances: the nil-rate band is £325,000, and her late husband's unused band transfers, giving £650,000. The residence nil-rate band is £175,000, and his transfers too — another £350,000 — because she is leaving the home to direct descendants. Total allowances: £1,000,000.

Her estate is £1.2m. The £200,000 above the allowances is taxed at 40%, so £80,000 goes to HMRC. She spent fifteen winters being cold to protect money, a chunk of which was never going to reach her children in the first place.

Three details make this sharper than it looks. The nil-rate band, the residence nil-rate band and the £2m taper threshold are all fixed at those levels up to and including the 2030 to 2031 tax year, so every year of house-price growth pushes more of an estate over the line without anyone deciding anything. Above £2m the residence band tapers away by £1 for every £2 of estate value, so larger estates lose it entirely. And leaving 10% or more of the net estate to charity cuts the rate on the rest from 40% to 36%.

There is a bigger change coming for anyone whose plan is to leave the pension untouched. From 6 April 2027, most unused pension funds and pension death benefits will count as part of the estate for inheritance tax — legislated in the Finance Act 2026, which received Royal Assent on 18 March 2026. Death-in-service benefits from a registered scheme, and dependants' scheme pensions from defined-benefit or collective money-purchase arrangements, are excluded. HMRC's own estimate is that of roughly 213,000 estates with inheritable pension wealth in 2027 to 2028, about 10,500 will face an inheritance tax bill that would not previously have arisen, and around 38,500 will pay more than they otherwise would. For someone whose entire strategy is never touch it, that is a material change in what never touching it produces.

The allowances almost nobody uses

These are rules, not recommendations — whether any of them suits you depends on your circumstances and your will, which is a conversation for an accountant or a solicitor rather than a website. But it is worth knowing they exist, because the underspender's instinct is to assume that any money leaving is money lost.

The point is not that you should be giving money away. It is that watching a grandchild use the money while you are alive is available, legal, and for many people the thing they actually wanted. Wills and the financial admin nobody enjoys covers the paperwork side of this properly.

The heating is not a rounding error

One specific version of this deserves saying plainly, because it is the one that ends badly. The NHS recommends heating the rooms you regularly use to at least 18°C, and links cold homes not just to colds and flu but to heart attacks, strokes, pneumonia and depression. A cold house is not thrift. It is a health decision being made by a spreadsheet that stopped being accurate about thirty years ago.

Two things worth knowing while we are here. The Winter Fuel Payment is worth between £100 and £300 for winter 2026 to 2027 if you were born on or before 27 June 1960 — and if your total income is over £35,000, HMRC takes it back, so some people receive it and repay it without ever noticing either event. And a great many people in this position have never had a benefits check done, on the grounds that they obviously would not qualify. MoneyHelper and Citizens Advice both do one free.

How to tell whether this is you

The question that unsticks it

What would have to be true for you to feel safe enough to spend some of it? If you cannot answer that, then the number was never what the feeling was about — and no amount of extra saving will settle it.

This is one of the places a projection genuinely helps, because the fear is specific and answerable: will I run out? A lifetime cashflow plan answers it with your own numbers, including the bad scenarios, which is a lot more convincing than being told you'll be fine.

A permission budget

Telling a lifelong saver to “enjoy it” does not work, because it asks them to override the exact instinct that built the money. A permission budget works better, because it is still a budget — it just runs in the opposite direction. Once a year:

Repeat it the following year with a slightly larger figure. What tends to shift is not the spending. It is discovering that the sky stays where it is, which is the only evidence this particular fear ever accepts.

Where coaching ends and advice begins

Everything above is coaching: understanding the pattern, knowing the rules exist, deciding what you want the money for. Several of the decisions it leads to are not. How much you can sustainably draw from a pension or an investment portfolio, when to take benefits, how to structure an estate, and whether any particular gift makes sense in your situation are regulated advice or legal work, and the sums are large enough to be worth paying for properly. Buzz Money Coach does not give regulated financial advice and is not authorised to. Where you need it, we will say so and can introduce you to Equity & General, authorised and regulated by the FCA (No. 474163) — entirely optional, with no obligation. Coach or adviser? sets out which of the two you actually need. MoneyHelper is government-backed, free and impartial if you would rather start somewhere with nothing to sell.

The saving was never the mistake. The instinct did its job, and it is precisely why there is something to argue about now. What it never got was an update — a message saying the danger passed some years ago and the terms have changed. Nobody sends that message. You have to work out what the money was for, put a figure on the part that is meant to be lived on, and then, awkwardly and against every instinct, spend it.

Questions people actually ask

Is it wrong to want to leave everything to my children?

Not at all, and nobody should talk you out of a plan you have chosen on purpose. The question is whether it is a decision or a default. A decision means you have looked at the numbers, know roughly what inheritance tax will take, know what you are giving up to leave the extra, and still want to. A default means the money is accumulating because spending it feels wrong, and the inheritance is the justification arriving afterwards. Worth adding: with people living longer, children commonly inherit in their own sixties, when they need it least. The same money given earlier, or spent on time together now, often does more.

How do I know whether I can actually afford to spend more?

This is the right question, and it has a proper answer rather than a reassurance. A lifetime cashflow plan projects your income, spending, pensions and investments forward year by year, then stress-tests them against the things you are actually afraid of: poor investment returns, high inflation, one of you needing care, living to 100. What comes back is not a promise, it is a range. Most careful savers find their spending could rise substantially before any scenario runs out of money. Being shown that in your own figures does what no amount of encouragement manages, because it engages the part of you that trusts numbers rather than opinions.

Can I give money away to reduce inheritance tax?

There are established exemptions: £3,000 a year, carried forward one year only; £250 to any number of individual people; wedding gifts of £5,000 to a child, £2,500 to a grandchild and £1,000 to anyone else; and regular gifts out of surplus income, which have no upper limit if you can genuinely afford them. Larger gifts leave your estate entirely after seven years, with taper relief between years three and seven where total gifts exceed £325,000. The real risk is not tax, though — it is giving away money you later need. Money handed over cannot be recalled if care costs arrive. Take advice before anything substantial.

My parent lives like this and it worries me. What can I do?

Arguing with the behaviour does not work, because the behaviour is not the point — the fear underneath it is, and it is usually decades old. Three things help more. Ask what they are afraid of, and let the answer be running out of money rather than something profound. Suggest a projection done by somebody independent, since the same figures land differently from a professional than from a child who might look like an interested party. And separate out anything with a health consequence, particularly a cold house or deferred dental and hearing care, and treat that as its own urgent conversation rather than part of the general one.
