Estate planning is the process of organising your affairs to ensure that what you've worked for is preserved, protected, and passed on according to your wishes — while minimising unnecessary costs and tax. In the UK in 2026, effective estate planning involves more than just writing a will: it encompasses Lasting Powers of Attorney, Inheritance Tax planning, trusts, pension nominations, and insurance.
HMRC collected £7.5 billion in Inheritance Tax in 2024/25 — a record high, driven largely by frozen thresholds and rising property values. With careful planning, many families can legally reduce or eliminate this liability while ensuring their loved ones are protected.
A comprehensive UK estate plan typically involves five key components:
Your will is the cornerstone of any estate plan. Under the Wills Act 1837, it must be in writing, signed by you in front of two independent witnesses who also sign. Without a valid will, the Rules of Intestacy apply — a rigid formula that rarely matches what people actually want.
Key will decisions include:
For straightforward estates, an online service like LegalWills.co.uk provides a fully valid will from £29.99. For complex estates, a solicitor is recommended.
An LPA appoints someone to manage your affairs if you lose mental capacity. There are two types:
Registration with the OPG costs £82 per LPA. The alternative — a Court of Protection deputyship — costs £3,000–£5,000 and takes months. The case for setting up LPAs is overwhelming. See our detailed guide on Lasting Powers of Attorney in the UK.
IHT is charged at 40% on estates above the nil-rate band threshold. Understanding the rules allows significant legal mitigation:
Every individual has a nil-rate band (NRB) of £325,000. Assets up to this value pass free of IHT. This threshold has been frozen since 2009 and is unlikely to increase before 2030 under current government plans.
An additional allowance of up to £175,000 is available when a main residence passes to direct descendants (children, grandchildren). This brings the individual threshold to £500,000, and for a married couple sharing both their NRBs and RNRBs, potentially £1 million.
The RNRB tapers away for estates above £2 million at a rate of £1 for every £2 above this limit.
All assets passing between UK-domiciled spouses or civil partners are completely exempt from IHT. This is a critical planning tool — many couples leave everything to each other on first death, then on the survivor's death the combined NRB and RNRB is available.
Leaving 10% or more of your "net estate" to charity reduces the IHT rate from 40% to 36%. For a charitable couple with an estate of £1.5 million, this could save over £20,000 in IHT while also benefiting a cause they care about.
The key gift exemptions are:
A will + two LPAs is your foundation. Compare UK services that cover both, starting from under £200 total for the complete package.

Trustees have discretion over how and when to distribute income and capital among a class of beneficiaries. Useful for: IHT planning, protecting vulnerable beneficiaries, and providing flexibility for changing circumstances.
One beneficiary (typically a surviving spouse) receives income from the trust assets during their lifetime. On their death, the capital passes to remainder beneficiaries (typically children). Useful for blended families where you want to provide for a spouse without leaving them free to redirect assets away from your children.
For disabled beneficiaries who receive means-tested benefits. A correctly structured trust can hold assets without affecting benefits eligibility. These are complex and require specialist legal advice.
All trusts in a will require solicitor drafting. They add cost but can save significant tax and provide vital protection.
One of the most overlooked aspects of estate planning is beneficiary designations on assets that pass outside the will:
Most occupational and personal pension funds allow you to nominate who should receive your pension pot on death. This is an "expression of wishes" — trustees have discretion but will usually follow it. Pensions are currently outside your estate for IHT purposes (though this is set to change from April 2027 under the Autumn Budget 2024 plans), making them extremely valuable IHT planning tools.
Life insurance paid into a trust on your death falls outside your estate and avoids IHT and probate. This is a simple and effective planning technique — ask your insurer about a trust deed.
Property owned as joint tenants automatically passes to the surviving owner on death — it does not go through your will. This can be efficient, but can also create problems if you intended the property to pass differently. Consider whether tenancy in common (owning separate shares that can be left by will) is more appropriate.
