TL;DR
How and why to write a UK life insurance policy in trust: the inheritance tax benefit, the speed of payout, the trust types commonly used, and the practical steps to set up a policy in trust.
Key facts
- A policy in trust pays out to the trustees for the beneficiaries, typically outside the insured's estate for IHT purposes.
- Trust paperwork is provided free by most UK insurers.
- Discretionary trusts allow trustees to choose how to distribute the payout among named beneficiaries.
- Absolute (bare) trusts give the named beneficiary a fixed entitlement.
- Trusts can speed up payout because trustees can claim without waiting for probate.
- ABI estimates only around half of UK life insurance policies are written in trust, despite the IHT and probate benefits.
- Discretionary trusts are the most common UK life insurance trust structure; bare trusts and split trusts are also used.
- Trust paperwork is typically free from insurers; the cost is in the time to complete and understand it.
- Trustees should be reliable adults; typically two or more are named, often including the policyholder and another trusted person.
Writing a UK life insurance policy in trust changes how the payout is handled on death. The payout passes to the trustees for the named beneficiaries, typically outside the deceased's estate for inheritance tax purposes and without waiting for probate. This article explains the mechanics and the trust types commonly used.
The IHT benefit
A policy outside the estate is not included in the IHT calculation. For estates above the nil-rate band, this can save 40% IHT on the policy payout. For estates within the nil-rate band, the IHT benefit is zero but the speed of payment can still matter.
Speed of payout
Without a trust, the payout typically goes into the deceased's estate and can only be paid out after probate, which often takes months. With a trust, the trustees can claim directly from the insurer once the death certificate is provided, often within weeks.
Discretionary vs bare trusts
A discretionary trust names possible beneficiaries and lets the trustees decide who receives what. It is flexible and useful when the policyholder's circumstances may change. A bare trust names a specific beneficiary with a fixed entitlement; once set, the beneficiary's entitlement cannot be changed.
Setting up a trust
Most insurers provide free trust forms. The policyholder completes the form naming trustees and beneficiaries and submits it to the insurer. Trustees should be reliable adults; typically two or more are named.
Considerations
Once in trust, the policyholder cannot change the trust without legal steps (and in the case of irrevocable trust elements, may not be able to change it at all). Trust structures should be reviewed alongside the will and the wider estate plan.
Why so few policies are in trust
ABI estimates only around half of UK life insurance policies are written in trust, despite the IHT and probate benefits. The main reasons for this gap include: lack of awareness among policyholders; reluctance to engage with the trust paperwork; concern about loss of flexibility; and (for some advisers) lack of focus on the trust placement at point of sale.
The cost of not writing in trust can be substantial. For a household above the nil-rate band with a GBP 300,000 life policy, the IHT saving from trust placement is GBP 120,000 (40% of GBP 300,000). The administrative time to complete a trust form is typically 30 to 60 minutes; the financial benefit per hour spent is among the highest of any UK financial admin task.
FCA Consumer Duty has placed additional focus on insurers ensuring customers understand trust placement options. Many insurers now actively prompt customers to consider trust placement at policy inception.
For policies already in place without trust, retrospective trust placement is typically possible by completing the insurer's trust form. The IHT and probate benefits apply from the date of trust placement, not the date of original policy issue.
Trust types in detail
Discretionary trusts name possible beneficiaries (such as 'spouse and children') and let the trustees decide who receives what. The trustees consider the family's circumstances at the time of claim; this provides flexibility for changing family situations.
Bare (absolute) trusts name a specific beneficiary with a fixed entitlement. Once set, the beneficiary's entitlement cannot be changed. Bare trusts are simpler than discretionary but less flexible.
Split trusts combine elements: typically, the death benefit goes to a discretionary trust for the family, while any critical illness benefit goes back to the policyholder. Split trusts allow critical illness payouts to support the policyholder during illness while preserving the death benefit for IHT-efficient transfer to family.
Bypass trusts can be used to direct life insurance proceeds away from the surviving spouse (who already has the spouse exemption) toward children or other beneficiaries, using up the deceased's nil-rate band efficiently.
The choice of trust depends on family circumstances, IHT planning structure, and the policyholder's preferences. Standard discretionary trusts work for most families; complex structures may require specialist legal advice.
Setting up a trust step by step
Most insurers provide free trust forms with their policy documentation. The policyholder completes the form naming trustees and beneficiaries and submits it to the insurer. The insurer records the trust and the trust takes effect.
The trustees are typically the policyholder plus at least one other person (often the spouse or a trusted family member). Some structures use a professional trustee (such as a solicitor or trust company) for additional impartiality, particularly for complex family situations.
Beneficiaries are typically named in classes (such as 'spouse and children') rather than specific individuals. This provides flexibility for future family changes; children born after the trust is set up are typically covered automatically.
The trust form should be witnessed by an independent adult; the insurer's specific witnessing requirements are in the form instructions. Some insurers require the witness to be unrelated to the trustees and beneficiaries; others have less strict requirements.
The completed trust form is returned to the insurer. The insurer confirms the trust placement and updates the policy records. The trust takes effect from the date of the insurer's acceptance, not the date the form was signed.
The IHT benefit in detail
A policy outside the estate is not included in the IHT calculation. For estates above the nil-rate band, this can save 40% IHT on the policy payout. For estates within the nil-rate band, the IHT benefit is zero (because the estate would not have been taxable anyway).
The nil-rate band is currently GBP 325,000 per individual. Plus the residence nil-rate band of up to GBP 175,000 where a main home passes to direct descendants. A couple with full transferable bands can pass up to GBP 1 million IHT-free.
For estates above these thresholds, trust placement of life insurance is a primary IHT planning tool. The policy can be substantial (often hundreds of thousands of pounds for higher earners with dependants); the IHT saving is correspondingly large.
The trust structure does not provide any IHT benefit for very wealthy estates where the trust assets themselves become taxable on certain anniversaries (under the 'periodic charge' rules for discretionary trusts). For most household-level policies, this is not a concern; the periodic charge rules apply at higher value thresholds.
Speed of payout in detail
Without a trust, the payout typically goes into the deceased's estate and can only be paid out after probate, which often takes months. With a trust, the trustees can claim directly from the insurer once the death certificate is provided, often within weeks.
The speed of payout matters particularly for dependants who need access to the funds quickly for funeral costs, ongoing household expenses, and major outgoings such as the mortgage. The probate process can take 6 to 12 months for straightforward estates; complex estates can take years.
The trustees of a discretionary trust have the discretion to make interim payments to beneficiaries pending the formal distribution of the trust. This further accelerates access to funds for dependants.
Choice of trustees and the practical setup
The choice of trustees affects how the trust operates in practice. Typical practice: name 2 or 3 trustees including the policyholder (during their lifetime) and at least one other reliable adult (often the spouse or another family member). The trustees should be willing to act and capable of handling the trust administration.
The trust form is typically free from the insurer. Completion takes 30 to 60 minutes; both the policyholder and the trustees sign, with a witness for each signature. The form is returned to the insurer who records the trust. From that point, the trust is in place and the IHT and probate benefits apply.

Frequently asked questions
Is there a cost to set up a trust?
Free trust forms are typically provided by the insurer. Legal advice on the trust structure may have a cost if used (typically GBP 100 to GBP 500 for straightforward advice; more for complex structures). Most households use the insurer's standard form without separate legal advice. The cost of advice is typically small relative to the IHT saving.
Can an existing policy be put in trust?
Yes. Most insurers accept trust forms on existing policies as well as new ones. The retrospective trust placement provides the IHT and probate benefits from the date of placement onwards. For policies that have been in place for years without trust, putting them in trust now still provides substantial future benefit.
Can the policyholder be a trustee?
Typically yes, alongside at least one other trustee. The policyholder may not be a beneficiary of their own life policy held in trust without specific IHT consequences. The typical structure is policyholder as trustee but not as beneficiary; spouse and children (or other family) as beneficiaries.
Does a trust override the will?
The trust applies to the policy payout. The will applies to the estate. Policies in trust are not affected by the will because they pass outside the estate. The trust trustees distribute the payout according to the trust deed; the will trustees distribute the estate according to the will. The two operate in parallel.
What happens if no trust is in place?
The payout typically falls into the estate, taking the time of probate to release and being included in any IHT calculation on the estate. For estates above the nil-rate band, the IHT cost can be substantial. For estates within the nil-rate band, the probate delay is the main cost rather than the tax cost.
Can children be trustees?
Typically no. Trustees must be adults (18+) with legal capacity. Naming children as beneficiaries is fine; naming them as trustees is not. Some trust structures appoint guardian-like adults as trustees to manage trust assets for children's benefit until they reach adulthood.
What if the trustees disagree?
Trust deeds typically include provisions for resolving disagreements (such as majority decisions or appointed mediation). For complex situations, court applications can resolve disputes. Choosing trustees who are likely to agree on family matters reduces this risk.
