Summary: Drawing on 46 years in life assurance and pensions, this article traces the history of back-to-back insurance from 1980s "Designed for Income" through to a modern application addressing the pension IHT crisis from April 2027. It introduces "Certainty3": using surplus pension income to fund whole of life premiums in trust. Worked example: £119,247 of pension fund generates £360,000 of life cover in trust, compared to approximately £43,000 the same money would deliver after tax if left in the pension.
Where It Started
I started at MGM Assurance in 1980. I was eighteen years old, and I had no idea that the next forty-six years would be spent watching the life assurance and pensions industry reinvent itself — sometimes brilliantly, sometimes catastrophically, and occasionally both at once.
One of the products that shaped my early understanding of how insurance could be used creatively was called "Designed for Income." It was, in essence, a back-to-back arrangement: the client purchased an annuity, and the income from that annuity was used to fund the premiums on a life assurance policy. The annuity provided income during life. The life policy replaced the capital on death. Simple. Elegant. Effective.
The product benefited from Life Assurance Premium Relief — LAPR — which gave tax relief on life insurance premiums. This made the economics particularly attractive. The premium was subsidised by the tax system, and the death benefit was delivered free of income tax.
Then, in 1984, LAPR was scrapped. The back-to-back concept lost its tax advantage, and the industry moved on. The idea was shelved. Other priorities took over. Pensions, SIPPs, drawdown, auto-enrolment — the landscape shifted, and back-to-back insurance became a historical footnote.
Fast-Forward: The Pension IHT Crisis
Forty-two years later, I read an article by Steve Webb — the former Pensions Minister — in the Daily Mail's This is Money column. He was answering a reader's question about inheriting a local government pension. The article reminded me of something I had known for decades but had not thought about in this particular context: the coming collision between pension funds and inheritance tax.
From 6 April 2027, most unused defined contribution pension funds will be included in the estate for inheritance tax purposes. This is not a minor adjustment. It is a structural transformation. Pensions that families have spent decades building — deliberately preserving them, deliberately spending other assets first — will suddenly form part of the taxable estate.
The double tax risk is severe. A pension fund taxed first at 40 percent IHT, then at the beneficiary's marginal income tax rate, can lose 64 percent or more of its value. For additional rate taxpayers, the effective rate can exceed 87 percent.
And it struck me: the back-to-back concept that worked so well in 1980, and was killed by the removal of LAPR in 1984, now has a modern application that requires no tax relief at all. The economics work purely on the basis of what the pension fund would otherwise deliver after tax — and what a properly structured insurance arrangement can deliver instead.
Certainty3
I call it Certainty3, because the two certainties in life — death and taxes — are well established. The third certainty is what you can create by coordinating the first two: a guaranteed, quantified, tax-free capital sum delivered to your family on death, funded by income that would otherwise be consumed by tax.
The concept is straightforward:
- A portion of the pension fund is used to purchase a joint life annuity
- The annuity provides a guaranteed income stream for life
- That income is used to fund the premiums on a whole of life insurance policy
- The whole of life policy is written in trust, outside the estate
- On the second death, the sum assured is paid to the trustees — free of inheritance tax
The Generational Problem
Before looking at the numbers, it is worth pausing to consider why this matters now more than at any point in the last forty years.
The baby boomer generation — broadly, those born between 1946 and 1964 — has been extraordinarily lucky in financial terms. They bought property before prices became prohibitive. They accumulated pension funds under favourable tax regimes. Many benefited from defined benefit schemes that their children will never see. They have, by historical standards, accumulated significant wealth.
Their children have not been so fortunate. Property is less affordable. Final salary pensions are largely extinct. Auto-enrolment contributions are modest. The state pension age is rising. The generation that will inherit from the boomers will, in many cases, be inheriting at a time when they most need the capital — and losing the largest portion of it to tax.
This is not a political observation. It is a planning reality. The families most exposed to the April 2027 changes are those with significant pension funds, moderate property wealth, and children who are higher or additional rate taxpayers. In other words, a very large number of families.
The Seven Advantages
Certainty3 is not a single-purpose tool. It addresses seven distinct planning objectives simultaneously:
The Seven Advantages of Certainty3
- 1. IHT removal: The annuity purchase removes capital from the estate instantly. There is no seven-year waiting period. The pension fund used to buy the annuity ceases to be part of the estate from the moment of purchase. The life cover, written in trust, was never in the estate.
- 2. Normal expenditure out of income: The premiums paid from annuity income may qualify as normal expenditure out of income under IHTA 1984 s21. This is an important exemption: gifts made from income (not capital), that form part of the donor's normal expenditure, and that leave the donor with enough to maintain their usual standard of living, are exempt from IHT. See: HMRC guidance on s21.
- 3. Life expectancy insight: The underwriting process for whole of life insurance provides independent medical scrutiny. If a medical condition is identified, this is information the family would want to know — both for personal health reasons and for planning purposes. If the applicant is rated or declined, this affects the planning strategy and may indicate a shorter time horizon for other estate planning measures.
- 4. Joint life annuity elegance: A joint life annuity continues to pay income until the second death. This means the insurance premiums continue to be funded for as long as either spouse is alive. The whole of life policy pays out on the second death — precisely when the IHT liability crystallises. The income stream and the death benefit are perfectly synchronised.
- 5. Two-trust structure: The whole of life policy is written in trust (outside the estate). If the family also has a lifetime property trust, the two structures complement each other. The property trust protects the home. The insurance trust provides liquidity. Together, they create a comprehensive estate protection framework.
- 6. IHT Pool: Where the IHT liability is large, Certainty3 can be used to create what I call the "IHT Pool" — a dedicated fund that exists solely to meet the inheritance tax bill. This removes the burden from executors, prevents forced asset sales, and gives beneficiaries certainty about what they will receive.
- 7. Transfer indicator: The combination of annuity purchase and insurance application provides a natural decision point. If the annuity rate is favourable and the insurance is available at standard rates, the strategy delivers maximum value. If either element is unfavourable, the family has clear information on which to base an alternative approach.
The Numbers: Mr and Mrs Smith
Let me illustrate with a worked example. The figures are based on current annuity rates and insurance premiums.
Worked Example: Mr and Mrs Smith, Both Age 65
Estate composition:
- Pension funds: £1,000,000
- Family home: £750,000
- ISAs and savings: £150,000
- Total estate: £1,900,000
IHT calculation (on second death, post-April 2027):
- Combined nil-rate bands: £650,000
- Combined residence nil-rate bands: £350,000
- Total available allowances: £1,000,000
- Taxable estate: £900,000
- IHT at 40%: £360,000
Certainty3 solution:
- Pension fund allocated to annuity: £119,247.17
- Joint life annuity income: £7,881.72 per year (guaranteed for life of both)
- Whole of life premium funded by annuity: £656.81 per month
- Sum assured (joint life, second death): £360,000
- Written in trust: outside the estate for IHT
The Alternative: Do Nothing
Comparison: Leave £119,247 in the Pension Fund
If Mr and Mrs Smith leave the same £119,247 in the pension fund, and both die after age 75 with the estate above the IHT threshold:
- Pension fund value: £119,247
- IHT at 40%: £47,699
- Remaining for beneficiaries: £71,548
- Income tax on withdrawal at 40% (higher rate): £28,619
- Net amount received by beneficiaries: £42,929
The same pension fund delivers more than eight times the value through Certainty3.
The Cost of Inaction
Every month of delay after April 2027 is a month in which pension funds are exposed to double taxation with no mitigation in place. The annuity rates available today may not be available tomorrow. The insurance premiums available at age 65 will be higher at age 66, 67, and every year thereafter — if insurance remains available at all.

Why This Works Now
The original back-to-back concept in 1980 required LAPR to be economically viable. When LAPR was removed, the numbers stopped working. But the pension IHT crisis from April 2027 creates a different economic justification entirely.
The comparison is no longer between a subsidised premium and an unsubsidised premium. It is between:
- Leaving money in a pension fund where it will be taxed at 64 percent or more, and
- Using that money to create a guaranteed, tax-free capital sum of many times the net value
The tax relief that made the 1980s product work has been replaced by the tax penalty that makes the 2027 product necessary. The mechanism is the same. The motivation is different. The outcome is even more compelling.
