As property prices and personal wealth have risen, more people are being affected by Inheritance Tax than ever before – often without realising it. Used alongside careful estate planning, whole of life assurance can provide a reliable source of cash to help cover IHT, protect long-term assets and reduce pressure on loved ones at a difficult time.

Why IHT is now a concern for more families

Inheritance Tax was once seen as something only the very wealthy needed to think about. That’s no longer the case.

While the rules themselves haven’t shifted much, their impact certainly has:

• The nil-rate band remains at £325,000¹ – frozen since April 2009
• The residence nil-rate band is still £175,000 – unchanged since 2017
• Property values and investment portfolios have continued to grow

As a result, more estates are now drifting over the IHT thresholds. Many families don’t spot this until it’s too late.

The problem isn’t just the size of the tax bill. It’s timing. Inheritance Tax is usually due before assets are sold – and estates are often tied up in property, family businesses or long-term investments. Accessing cash quickly can be difficult.

This is where sensible protection planning can help.

What is whole of life assurance?

Whole of life assurance is an insurance policy that pays out a guaranteed lump sum when you die – whenever that happens – provided premiums continue to be paid.

In the context of estate planning, it’s often used to create a known amount of money that can be used to help meet an Inheritance Tax bill.

For couples, policies are frequently set up on a joint life, second death basis. This means the payout only occurs after the second person has died – which is typically when IHT becomes payable.

Put simply, whole of life assurance is often used to:

• Create certainty about future cash
• Make funds available quickly, outside the estate
• Reduce the risk of families having to sell assets under pressure

This isn’t about clever tax tricks. It’s about giving loved ones time, space and flexibility when they need it most.

Why long-term affordability matters

Whole of life assurance is a long-term commitment. That means the structure really matters.

Good advice should focus on:

• Whether premiums are affordable now – and likely to remain so
• How premiums could change over time
• How the policy fits with your broader financial and estate plans

Regular reviews are essential. Life changes, and your planning needs to change with it. Whole of life assurance works best when it’s part of a joined‑up approach, not a standalone decision.

Why policies are often written into trust

When whole of life assurance is used for Inheritance Tax planning, the policy is usually placed into trust.

This helps to ensure the payout:

• Falls outside your estate for IHT purposes
• Doesn’t get delayed by probate
• Can be accessed quickly by the right people

Trusts can be very effective, but they aren’t something to set up lightly. They bring responsibilities, rules and ongoing obligations that need to be clearly understood.

The key point is this – a trust is a tool, not a solution in its own right. It should be used carefully and reviewed regularly to make sure it still does what it’s meant to do.

Looking beyond the payout figure

A common mistake is to focus only on the headline sum assured – the amount the policy will eventually pay out.

Over time, other factors can matter just as much:

• The total cost of premiums
• How long those premiums are expected to continue
• How the policy interacts with the rest of your estate

Taking a long‑term view is essential. Whole of life assurance should only be used where it genuinely supports your objectives and remains sustainable. Typically, whole of life assurance premiums can be quite expensive because the insurance expects a guaranteed pay out. They can also commonly be structured with what’s called a reviewable premium, which is likely to increase as you age. This might mean you need to pay more or have less cover.

Using surplus income to fund premiums

You might want to pay for premiums using surplus income – income that isn’t needed to maintain your normal standard of living.

For this approach to work properly:

• Payments must be made from income, not capital
• They should be regular and consistent
• Your lifestyle shouldn’t be affected

When set up and documented correctly, this can sit neatly alongside wider estate planning. But it depends on good records and regular reviews – particularly if income or spending patterns change.

Final thoughts

Used thoughtfully, whole of life assurance can bring clarity and control to Inheritance Tax planning.

It can help to:

• Meet IHT liabilities without rushed decisions
• Protect assets built up over many years
• Give loved ones breathing space at a difficult time

With Inheritance Tax thresholds frozen and estate values continuing to rise, reviewing your arrangements – and keeping them under review – can make a meaningful difference.
