The missing half of the plan
Every other guide on this site assumes a future in which you keep earning, stay healthy, and remain able to sign your own name. Most of the time that’s exactly what happens. But a financial plan that only works when nothing goes wrong isn’t a plan — it’s a forecast. The emergency fund guide argues that a cash buffer is what lets you invest aggressively everywhere else; this guide is the same argument carried to its conclusion. The emergency fund covers the boiler and a few months between jobs. It does not cover the two genuinely ruinous scenarios: losing your income for years, and dying or losing capacity while people depend on you.
None of this is fun to think about, which is precisely why the people who most need it — thirties and forties, mortgage, young children, everything resting on one or two salaries — most reliably haven’t done it. The whole list below costs a few hundred pounds and a few evenings, and most of it you’ll never think about again.
Start with what you already have
Before buying anything, find out what’s already in place — it changes what you need to buy.
- Employer sick pay. Ask HR (or check your contract) how long full pay continues if you’re off sick. Some employers pay six months full and six months half; many pay only the legal minimum. That minimum is statutory sick pay — roughly £120 a week for a maximum of 28 weeks, then nothing. If your household couldn’t run on that, keep reading.
- Death-in-service. Many employers provide life cover of 2–4× salary automatically. It’s real cover, but it evaporates when you change jobs — so treat it as a bonus, not the plan. Make sure you’ve completed the nomination form saying who it goes to.
- Pension expression of wish. Your pension pot doesn’t pass by your will — the scheme trustees decide, guided by a nomination form most people have never filled in. Five minutes on each provider’s website. Do it today; it’s free.
- State benefits. Universal Credit and Employment and Support Allowance exist, but they are means-tested or modest, and anyone with savings or a working partner may get little. They are a floor, not a plan.
Income protection — the cover almost nobody has
If you’re under 50, you are several times more likely to be off work sick for months or years before retirement than to die before it. Yet life insurance outsells income protection many times over, mostly because life cover is what gets cross-sold with mortgages.
Income protection pays a monthly, tax-free income — typically 50–65% of gross salary — if illness or injury stops you working, and keeps paying until you recover, return to work, or hit the policy’s end age (set this at your expected retirement age). The variables that matter:
- Deferral period — how long you wait before it pays: 4, 8, 13, 26 or 52 weeks. Longer deferral, cheaper premium. Match it to your employer sick pay plus emergency fund: six months of full pay plus a solid cash buffer justifies a 26-week deferral at a much lower cost.
- Own occupation — insist on it. It pays if you can’t do your job; the cheaper “suited occupation” or “any occupation” definitions can refuse to pay a surgeon who could theoretically stack shelves.
- Guaranteed premiums — fixed for the policy’s life, versus “reviewable” ones the insurer can raise later. Guaranteed usually wins over decades.
- Index-linked benefit — so a payout that starts in 2046 isn’t fixed at 2026 prices.
Cost scales with age, health, smoking and occupation class — a healthy thirty-something office worker might pay £20–£40 a month for meaningful cover to age 67. The self-employed, who get no sick pay at all, need this most and buy it least. Budget option: a shorter payment period (each claim pays for a maximum of 2 years) covers the most common absences at maybe half the premium — less good than full-term cover, far better than nothing.
Life cover — cheap, boring, and only if someone depends on you
No dependants and no joint mortgage? You may not need life insurance at all — skip to the will. For everyone else, the default answer is term insurance: it pays out only if you die within the term, which is why it’s cheap — for a healthy non-smoker in their thirties, hundreds of thousands of pounds of cover typically costs £10–£30 a month.
- Decreasing term tracks a repayment mortgage down to zero — the cheapest way to make sure the house is paid off.
- Level term pays a fixed lump sum any time in the term — for replacing years of income or funding children to independence.
- Family income benefit is the underrated one: instead of a lump sum it pays a monthly income until the end of the term (say, until the youngest child is 21). It matches what a family actually loses — a salary — and it’s usually the cheapest of the three.
A common-sense sizing check: mortgage balance, plus roughly 10× the income you’re replacing if children are young, minus existing death-in-service. Couples should price two single policies rather than one joint policy — often barely more expensive, and it pays out twice if the worst happens twice.
Write it in trust. Ask the insurer for the (free) trust form when you take the policy out. In trust, the payout goes straight to your beneficiaries in weeks, outside your estate — rather than sitting in probate for months and potentially swelling an inheritance-tax bill. Almost nobody is told this; almost everybody should do it. (Pensions have their own version of this problem from April 2027 — see the pensions and inheritance tax guide.)
Critical illness cover pays a lump sum on diagnosis of specified serious conditions (cancer, heart attack, stroke and a long list of definitions that vary by insurer). It’s substantially more expensive than life cover and the definitions are where claims get contested. If the budget only stretches to one thing, income protection covers more scenarios for the money; critical illness is the “nice to have on top”, not the foundation — despite usually being sold the other way round.
What to skip: accidental-death policies (cover so narrow it rarely pays), mortgage payment protection insurance sold with the loan, over-50s plans that can pay out less than you put in, and the free “£10,000 of parent cover” marketing hooks — none of these is a substitute for the real products above. Buy through a whole-of-market broker or comparison, disclose your health honestly (non-disclosure is the main reason claims fail), and never cancel an old policy before the replacement is live.
A will — or the state writes one for you
Die without a will and the intestacy rules decide everything. In England and Wales: a spouse or civil partner gets your personal possessions, the first £322,000 and half of the rest — with the other half going to your children, even if that forces the family home to be sold. An unmarried partner gets nothing, however long you’ve been together and whatever you’d have wanted. Scotland and Northern Ireland have different rules, but the same principle: no will, no say.
A will also does the job no insurance can: it names guardians for your children. Without it, the courts decide who raises them.
The practicalities are easier than the procrastination suggests:
- A solicitor-drafted will costs roughly £150–£300 (a couple’s “mirror wills” a little more) and is the right answer for anything non-trivial: children from previous relationships, a business, foreign property, or an estate near the inheritance-tax threshold.
- Reputable online will services handle simple estates for under £100. Free Wills Month (March and October, for over-55s) and Will Aid (November) get you a solicitor will for a charity donation.
- Wills need two independent witnesses (not beneficiaries or their spouses), and the original needs a home your executors can find.
- Marriage or civil partnership revokes an existing will in England, Wales and Northern Ireland — remarry and your old will is void. Divorce doesn’t revoke one, but treats the ex-spouse as having died. Review the will at every big life event, and every five years regardless.
Lasting power of attorney — the one people regret not having
Death isn’t the only way to lose control of your affairs — a stroke, an accident or dementia can leave you alive but without mental capacity. Without paperwork in place, nobody, including your spouse, has automatic authority over your accounts: joint accounts can be frozen, and your family’s only route is applying to the Court of Protection for a deputyship — a process that takes months, costs thousands, and puts a court, not you, in charge of choosing who acts for you.
The fix is a lasting power of attorney (LPA), made while you’re healthy. There are two types, and you want both:
- Property and financial affairs — bank accounts, bills, investments, selling the house if care needs to be funded.
- Health and welfare — care decisions, medical treatment, where you live. Only usable once capacity is lost.
In England and Wales you can do the whole thing yourself on the government’s online service; registration costs £82 per LPA (so £164 per person for both types, with reductions on low incomes). Scotland and Northern Ireland have their own equivalents (a power of attorney registered with the OPG Scotland; an enduring power of attorney in NI). Choose attorneys you trust completely, name a replacement in case your first choice can’t act, and register now rather than “when needed” — registration takes weeks and an unregistered LPA is just paper. For a couple in their thirties this feels absurdly premature; that is exactly the time to do it, because you can’t make one after the point at which you need it.
The order to do it in
- Free and instant: pension expression-of-wish and death-in-service nomination forms.
- This month: a will each, with guardians named if you have children.
- This quarter: income protection sized around your sick pay and emergency fund; life cover (in trust) if anyone depends on your income.
- This year: both LPAs each, registered.
Then put a recurring reminder in your calendar to re-check the lot at every big life event — marriage, children, house move, new job — and get back to the cheerful business of compounding.
The one-line summary
Protect the income first, then the dependants, then the paperwork: income protection matched to your sick pay, term life cover written in trust if anyone relies on you, a will that names guardians, and both LPAs registered while you’re well — the few hundred pounds that makes the rest of the plan crash-proof.
