What Is Estate Planning UK? (2026): A Complete Guide to the Five Key Documents
Updated 13 May 2026 · 12 min read · England & Wales
Quick answer
Estate planning is the process of organising your legal, financial and personal affairs so the right people receive your assets, someone you trust manages your finances and healthcare if you lose capacity, and inheritance tax is minimised. In England and Wales, a complete estate plan covers five documents: a will, a Property & Financial Affairs LPA, a Health & Welfare LPA, a pension nomination, and a letter of wishes. Most people can set up all five for under £400.
What is estate planning?
Estate planning is not just for the wealthy or elderly. It is the practical process of putting legal documents in place so that — whatever happens to you — your assets go to the right people, your healthcare wishes are respected, and the people you love are protected.
In England and Wales, an estate plan addresses two scenarios:
- Death: A will decides who inherits, who administers the estate, and who cares for minor children. Without one, the intestacy rules decide — and they often produce the wrong outcome.
- Incapacity: A Lasting Power of Attorney (LPA) gives a trusted person the legal authority to manage your finances and make healthcare decisions if you lose mental capacity. Without one, your family faces a Court of Protection application costing thousands of pounds and months of delay.
The five documents every UK adult needs
Will
What happens to your estate on death
A will appoints your executor, decides who inherits your estate (and in what shares), appoints a guardian for minor children, and creates any trusts needed to protect beneficiaries. Without a will, the intestacy rules apply: an unmarried partner receives nothing; your estate is divided by a statutory formula regardless of your wishes.
Property & Financial Affairs LPA
Who manages your money if you lose capacity
This LPA authorises your chosen attorney to manage your bank accounts, pay your bills, handle your property, deal with investments, and make financial decisions on your behalf. It can be used before capacity is lost (with your consent) or after. Without one, banks freeze accounts and no one can access funds.
Health & Welfare LPA
Who makes medical decisions if you lose capacity
This LPA authorises your attorney to make healthcare and personal welfare decisions — including where you live, your care arrangements, and (if you grant specific authority) decisions to refuse life-sustaining treatment. Unlike the financial LPA, it can only be used when you lack capacity for the specific decision.
Pension nomination form
Who receives your pension death benefits
Pensions do not pass through your will — they are controlled by an expression of wishes (nomination form) held by your pension provider. The trustees have discretion, but they almost always follow a current, completed nomination. Without a nomination, trustees decide who benefits. From April 2027, unused pension pots above available nil-rate bands will also be subject to IHT.
Letter of Wishes
Guidance for your executors and trustees
A letter of wishes is a non-binding personal document that explains the reasoning behind your will, provides guidance to trustees on how to exercise discretion, and records personal wishes that would be inappropriate in a formal legal document (funeral preferences, messages to loved ones, how to distribute personal items). Though not legally binding, it is usually followed.
Additional documents worth having
Funeral Wishes Planner
Records your preferences for burial vs cremation, service type, and any specific requests. Not a prepaid plan, but prevents family conflict and guesswork. From £15.

Documents all online accounts, passwords (stored securely), devices, and digital assets so executors can locate and manage them. From £15.
Executor Guide
Walks your named executor through the full 12-month probate process — from registering the death to final distribution. From £25.
Life insurance in trust
Writing your life insurance policy in trust removes the payout from your estate — saving IHT and bypassing probate. Free to set up through your insurer.
The cost of not planning
Estate planning feels optional until it isn’t. The financial and emotional cost of a failed or missing estate plan is almost always far higher than the cost of planning:
| Problem | Cause | Typical cost |
|---|---|---|
| Unmarried partner inherits nothing | No will — intestacy rules | Entire estate to relatives instead |
| Court of Protection Deputyship | No LPA — incapacity crisis | £3,000–£5,000 + ongoing supervision fees |
| RNRB forfeited | Property in discretionary trust in old will | Up to £140,000 in additional IHT |
| Contested will litigation | Unclear will or no letter of wishes | £10,000–£100,000+ |
| Pension goes to wrong person | Outdated nomination form | Entire pension pot to wrong beneficiary |
Estate planning timeline — how long does it take?
A complete estate plan does not need to take months. Here is a realistic timeline:
- Day 1: Complete your WillSafe UK will kit (1–2 hours). Print, sign, and have witnessed. Your will is immediately legally valid.
- Day 1: Complete your pension nomination form online (15 minutes).
- Week 1: Complete the two LPA forms using the OPG online tool. The WillSafe LPA Guidance Pack walks you through this step by step.
- Weeks 2–10: OPG registration in progress (currently 8–10 weeks). No further action required.
- Week 10: Receive registered LPAs. File with will. Tell your chosen executor where documents are stored.
Total active time: 3–4 hours. Total elapsed time: 10 weeks (driven entirely by the OPG registration queue, not by you).
Frequently asked questions
What does estate planning mean in the UK?+
Estate planning is the process of organising your legal, financial and personal affairs so that the right people inherit your assets on death, someone you trust can manage your finances and healthcare if you lose mental capacity, inheritance tax is minimised within the law, and your wishes about medical treatment and end of life are documented. A complete UK estate plan includes at minimum a will and two Lasting Powers of Attorney. Most people also benefit from a pension nomination, life insurance in trust, and a letter of wishes.
Do I need estate planning if I don't have much money?+
Yes. Estate planning is not just for the wealthy. Even a modest estate — a jointly owned flat, a pension, a bank account — needs a will and LPAs. Without a will, your estate follows the intestacy rules: an unmarried partner receives nothing, and the people you intended to benefit may not. Without an LPA, if you have a stroke or accident and lose capacity, your family must apply to the Court of Protection for a Deputyship order — a process costing £3,000–£5,000+ and taking months. A basic estate plan costs under £200 and takes a few hours.
When should I start estate planning in the UK?+
The best time to start is before you need it. Most people trigger estate planning by a major life event — buying a property, getting married or divorced, having children, reaching retirement. But incapacity or death can occur at any age: strokes, accidents, and sudden illness affect people in their 30s and 40s. A will and LPAs made at 35 with a healthy lifestyle are better than an LPA crisis application at 75. Reviewing your documents every 3–5 years or after each major life event is best practice.
What is the difference between a will and an LPA in the UK?+
A will operates after death — it appoints an executor, decides who inherits your assets, and appoints a guardian for any minor children. A Lasting Power of Attorney (LPA) operates during your lifetime if you lose mental capacity — it appoints attorneys to manage your finances and property (Property & Financial Affairs LPA) or make health and welfare decisions (Health & Welfare LPA). You need both: an LPA with no will means your affairs are managed during incapacity, but your estate falls to intestacy on death. A will with no LPA means your estate is handled properly on death, but a crisis incapacity event leaves your family with no legal authority to act.
How much does estate planning cost in the UK in 2026?+
A basic estate plan — will + two LPAs — costs £384–£1,500 depending on how you do it. A DIY approach: WillSafe UK single will (£39.99) + two LPA government fees (£92 × 2 = £184) = approximately £224. Using a will writer for all three: £500–£900. Using a solicitor for all three: £900–£2,500+. Complex estates with trusts, significant IHT exposure, or foreign assets may cost considerably more. The cost of not planning — Court of Protection fees for Deputyship, intestacy disputes, IHT on assets that could have been sheltered — typically dwarfs the planning cost.
What happens if you die without an estate plan in the UK?+
Without a will, the intestacy rules under the Administration of Estates Act 1925 decide who inherits — and the outcomes are often not what people intend. An unmarried partner receives nothing regardless of how long they lived together. Children from a previous relationship may lose out. The estate passes through a statutory formula rather than your wishes. Without LPAs, a sudden loss of capacity triggers a Court of Protection application costing thousands of pounds and months of delay — during which no one has legal authority to pay your bills or make health decisions on your behalf. Both gaps are closed by a will and two LPAs.
Can I do estate planning myself without a solicitor in the UK?+
Yes, for most straightforward estates. Will-writing is not a reserved legal activity in England and Wales — anyone can write a legally valid will, and DIY will kits have been used for decades. LPAs are also DIY-able using the official OPG online tool (LPA Online) and the £92-per-LPA registration fee. Professional advice is recommended for: complex IHT mitigation, trusts, blended families, foreign assets, or business interests. A WillSafe UK will kit and LPA Guidance Pack cover most people's needs at a fraction of solicitor costs.
