Will Writing Cost Calculator UK 2026

1. UK will writing prices 2026 — every provider compared

The UK will writing market is partially deregulated. Will-writing is not a "reserved legal activity" under the Legal Services Act 2007 (compare conveyancing and probate which are reserved). This means literally anyone can charge to write a will — but the regulation, insurance and complaints recourse vary dramatically by provider type.

Source: published price lists of named providers (April 2026), SRA Transparency Rules listings, Citizens Advice will writing research 2024, Law Society pricing survey 2024. Free will months (Co-op Will Service "Will Month", Cancer Research UK "Free Wills Month" October) are operated via SRA-regulated solicitor panels — same legal protection, charity donation suggested.

2. DIY wills — when £20 is enough (and when it isn't)

A DIY will using a stationery template (WHSmith, Lawpack, Co-op Will Pack) costs £10-£25. It is legally valid IF executed correctly per s.9 Wills Act 1837. The savings versus solicitor are substantial — £150-£500 — but the false economy can be catastrophic.

When DIY is suitable

• Simple estate: one home, UK bank accounts, ordinary investments
• Straightforward beneficiaries: spouse + children with no exclusions
• No business or partnership interests
• No second-marriage / blended family complications
• No foreign property or international beneficiaries
• No need for tax planning (estate well below £325,000 NRB)
• You understand the residuary clause concept
• You can find two competent adult witnesses present at the same time

Top DIY will mistakes

1. Witness inheriting — s.15 Wills Act 1837 voids any gift to the witness or their spouse. Use neutral witnesses (e.g. neighbours, not the beneficiaries)
2. No residuary clause — failure to specify who receives the remainder triggers partial intestacy for the unallocated portion
3. Joint property misunderstanding — joint tenancy property passes by survivorship outside the will; only tenancy in common shares form part of the estate
4. Unclear gift wording — "my house" if you own two; "the children" if some are step-children
5. Failure to update after marriage — marriage automatically revokes existing will (s.18 Wills Act 1837) unless made "in contemplation of marriage"
6. Pension and life insurance assumptions — pension death benefits typically pass via trustee discretion not the will; nominate beneficiaries via the scheme
7. Foreign property errors — French / Spanish / Italian property may be subject to forced heirship rules not overridden by an English will
8. Inadequate executor appointment — single named executor with no substitute
9. Failed gifts — gifting a specific asset that the testator no longer owns at death (ademption)
10. No guardianship for minor children — appointing a guardian under the Children Act 1989 s.5

The Law Commission's research for the 2017 Consultation Paper on Wills found that home-made wills account for approximately 38% of contested probate cases despite being only 15-20% of all wills.

3. Online will services — Farewill, Beyond, MakeMyWill compared

Online will services have transformed the consumer market since 2015. The leading providers use a guided online questionnaire then have an SRA-regulated solicitor review the output. Prices have stabilised in the £60-£200 range for single wills.

What online services typically DON'T cover

• Complex trust structures (discretionary, life interest, vulnerable persons)
• Foreign property / cross-jurisdictional wills
• Business succession planning
• Bloodline trust / generational wealth planning
• Inheritance Tax mitigation beyond basic RNRB / NRB
• Letters of Wishes for discretionary trust beneficiaries
• Severance of joint tenancy (separate Form A required)
• Living wills / advance decisions (sometimes — Farewill includes basic version)
• Mental capacity assessment (vital for elderly / vulnerable testators)

Best practice: online services are excellent for simple wills (60-70% of consumer wills). Above estate value £500,000, business interests, second marriages, foreign property or vulnerable beneficiaries — pay for an SRA-regulated solicitor.

4. Will writers — IPW members and the regulated landscape

The Institute of Professional Willwriters (IPW) is the principal voluntary trade body for unregulated will writers in England & Wales. Founded 1991, IPW members must hold minimum £2 million professional indemnity insurance, follow a Code of Practice approved by the Trading Standards Institute (under CMA-approved scheme), offer a 14-day cooling-off period, and submit to internal complaints handling.

The Legal Services Act 2007 - why will writing isn't reserved

The 2007 Act listed six "reserved legal activities" (rights of audience, conduct of litigation, reserved instrument activities including conveyancing, probate activities, notarial activities, administration of oaths). Will writing was deliberately excluded from this list — the Legal Services Board has consulted multiple times (2013, 2018, 2024) on whether to add it, with strong industry support from the SRA and Law Society. As of May 2026 the consultation remains open.

Citizens Advice research (2011, updated 2020) identified poor will drafting as the principal consumer detriment. The TSB Wills Service controversy (2014) — TSB Bank was paying introducer fees to unregulated will writers who routinely sold expensive trust products — led to the Office of Fair Trading investigation and the IPW's voluntary Code Approval.

5. Solicitor wills — SRA regulation and PII guarantees

SRA-regulated solicitors are bound by extensive regulation that provides materially stronger consumer protection than any other will-writing route:

• Mandatory PII £3 million minimum per claim, with minimum terms covering negligence (e.g. invalid will drafted, missed IHT planning) — SRA Indemnity Insurance Rules
• SRA Compensation Fund: protects clients against dishonesty (rare but devastating) — claims up to £2 million per matter
• Legal Ombudsman: free independent complaints route — orders up to £50,000 in redress
• Run-off cover: 6 years' indemnity continues after the firm closes (vital because negligence is often discovered post-death, 20+ years after the will was drafted)
• Client money rules: SRA Accounts Rules ringfence client funds
• CPD requirement: annual reflective continuing professional development
• SRA Code of Conduct: explicit duties on competence, independence, confidentiality
• Solicitors Act 1974 s.57: agreed fee is enforceable as contract — protection against price hikes

Why this matters for wills

Will negligence claims are unique because they often emerge 10-30 years after the will is drafted — when the testator dies and a flaw becomes apparent. White v Jones [1995] UKHL 5 established that a disappointed beneficiary can sue the solicitor in negligence even though no contract exists between them. The SRA's mandatory run-off cover is essential — a will writer's PII may have lapsed by the time the claim arises.

Where to find an SRA-regulated solicitor: The Law Society's "Find a Solicitor" searches all 200,000+ practising solicitors by specialism. The Society's Private Client accreditation marks experienced will and probate practitioners. STEP-qualified solicitors have specialist trust and estate qualifications.

6. Mirror wills — what couples need to know

Mirror wills (also called reciprocal wills) are the standard arrangement for married couples and civil partners. Each partner makes a separate will with broadly identical terms — typically leaving everything to the surviving spouse on first death, then to the children equally on second death.

Cost savings on mirror wills

Mirror vs mutual wills

Important distinction:

• Mirror wills: separate, identical-looking wills — either party can change theirs at any time during life without notice to the other. Standard arrangement for most couples
• Mutual wills: binding agreement that neither party will change their will after the death of the first (Re Dale [1994] Ch 31) — creates a constructive trust enforceable by the intended beneficiaries against the survivor. Rare and treated with caution by solicitors

Mutual wills frequently lead to litigation. The Law Society discourages them in most cases — for second-marriage families a life-interest trust will is usually a better solution. STEP guidance recommends written agreement evidencing mutual intent if used at all.

Second marriage / blended family solutions

Common scenarios needing more than mirror wills:

• Each partner has children from previous relationship — want survivor to live in home but children to inherit eventually → Immediate Post-Death Interest (IPDI) life interest trust will
• Vulnerable beneficiary (e.g. disabled child needing means-tested benefits preserved) → Vulnerable Persons Trust (VPT)
• Concern over survivor remarrying and disinheriting first marriage's children → discretionary trust will with letter of wishes
• Bloodline protection (asset preservation through divorces and bankruptcies) → Discretionary bloodline trust
• Significant IHT exposure → multiple residuary structures combining NRB / RNRB / charitable giving

7. Lasting Power of Attorney — the essential companion to a will

A will deals with what happens after death; a Lasting Power of Attorney (LPA) deals with what happens if you lose mental capacity during life. Both are part of a complete estate plan. LPAs are governed by the Mental Capacity Act 2005 and registered with the Office of the Public Guardian (OPG).

Two types of LPA

LPA fee exemptions and remissions

• Full exemption: gross annual income under £12,000 and receiving certain means-tested benefits (Income Support, Universal Credit, Income-related ESA, Pension Credit Guarantee, Housing Benefit, Working Tax Credit/Child Tax Credit, Local Housing Allowance)
• 50% remission: gross income £12,000-£14,000, or no benefits but evidence of low income
• Donor-only application: even if the attorney has higher income, only the donor's circumstances matter for LPA1A/LPA1B exemption
• How to apply: form LPA117 submitted with the LPA application

Why LPAs matter more than wills (for many)

1 in 14 over-65s has dementia (Alzheimer's Research UK 2024). Without an LPA, family members face Court of Protection deputyship — typical cost £400 application fee + £500-£2,000 in legal costs + £125 annual supervision fee. Multiple-year delays for routine matters. The LPA at £82 + £150 in legal fees is dramatically cheaper than the Court of Protection alternative.

2024 OPG statistics: 7.1 million LPAs registered (vs only 24 million UK adults with wills). The gap is well-known — most people overlook the LPA. Most solicitors now include LPA preparation as a "wills + LPA package".

8. Trusts in wills — when complexity justifies the cost

Approximately 15-20% of UK wills create a trust on death. These trust wills cost more (£500-£5,000+) but deliver significant benefits for the right circumstances.

STEP qualification — the gold standard for trust wills

The Society of Trust and Estate Practitioners (STEP) is the global professional body for trust specialists. STEP members hold TEP designation (Trust and Estate Practitioner) requiring 4-year diploma equivalent or 2-year STEP Diploma in International Trust Management. Solicitors who are STEP-qualified typically charge 10-20% more for will drafting but their work is markedly more reliable for trust wills.

The Law Society maintains a Private Client Section accreditation that overlaps. For estates above £325,000 NRB or where any trust is involved, STEP-qualified solicitors are recommended.

9. Will storage — where to keep the original

The original will is required for probate — photocopies are generally not accepted by HMCTS. Where the original is missing, the doctrine in Sugden v Lord St Leonards (1876) requires the executor to prove execution from secondary evidence, often costing thousands.

Certainty National Will Register

Operated by Certainty Will Search Limited, this is the principal UK will register. £42 one-off registration records the location (not the contents) of the will. Probate practitioners search the register on every probate application — finding a will registered there avoids accidental intestacy if the original is misplaced. Recommended by the Law Society.

Tell your executors

Whatever storage you choose, tell your executors where the will is. A common scenario: will stored at a firm that has since merged 3-4 times, executor cannot trace the file, family draws up an intestacy application, then the original is discovered post-distribution. Result: messy partial revocation, possibly fresh probate application, family disputes.

10. Codicils and updating your will

A codicil is a formal supplement to an existing will. It is read together with the original to constitute the testamentary disposition. The same execution requirements (s.9 Wills Act 1837) apply — written, signed, two witnesses present together.

Codicil vs full rewrite

• Codicil suitable for: changing one executor; adding a small specific gift; changing a charity beneficiary; updating an address
• Full rewrite needed for: marriage / divorce; new home purchase; new child; substantial estate value change; tax law change; new business interest
• The 3-codicil rule: many solicitors recommend writing a fresh will after a third codicil — risk of contradiction or ambiguity rises rapidly

Marriage automatically revokes a will

Section 18 Wills Act 1837: marriage revokes any prior will (unless made "in contemplation of marriage" — wording must be explicit). Divorce does NOT revoke the will but treats the former spouse as predeceased for gifts (s.18A Wills Act 1837 inserted by the Law Reform (Miscellaneous Provisions) Act 1995). After divorce: review and rewrite.

11. Living wills and advance decisions

The advance decision to refuse treatment (popularly called a "living will") is a legally binding document under sections 24-26 of the Mental Capacity Act 2005. It allows a person aged 18+ with capacity to refuse specified medical treatments — including life-sustaining treatment — should they later lose capacity.

Key requirements

• In writing (life-sustaining treatment refusal must be in writing)
• Signed by the maker, witnessed by one adult
• Explicit statement: "even if life is at risk" — required for life-sustaining treatment refusal
• Specifies treatments refused and circumstances (e.g. "if permanent vegetative state, refuse artificial nutrition and hydration")
• Capacity at time of making — important for vulnerable testators
• Distinct from Health & Welfare LPA: living will refuses, LPA appoints decision-maker
• Can be overridden by later valid LPA covering the same matter

Cost of advance decisions

Best practice: discuss your advance decision with your GP and family, give a copy to your GP for inclusion in your medical record, and store the original alongside your will.

12. Solicitors Act 1974 protections

Section 57 of the Solicitors Act 1974 makes any agreed fee enforceable as a contract. The SRA Code of Conduct rule 8.7 (Standards & Regulations 2019) requires solicitors to provide clear price information at the outset and regular updates. For will writing specifically you should obtain in writing:

1. Fixed fee or hourly rate, with grade of fee earner doing the work
2. VAT statement (added or included — typically £150 + VAT £30 = £180)
3. Number of meetings / phone calls included
4. What is in scope (single will, mirror wills, LPA, trust drafting)
5. What is out of scope (probate, contested matters, foreign property advice)
6. Storage: free, with subscription, or separate fee
7. Updates: cost of codicils, free first amendment, subscription model
8. Trigger for cost review: e.g. notify if exceed estimate by 20%
9. Funding options: payment plan, deferred billing
10. Complaints procedure: 8-week internal then Legal Ombudsman

14-day cooling-off

Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, contracts entered into away from business premises (e.g. solicitor home visit) carry a 14-day cooling-off period. This applies to most will writers selling at home. Use this — it allows time to consider alternatives.

13. Free Wills Months and charity will services

Several initiatives offer free or subsidised solicitor-drafted wills in exchange for a suggested charity donation:

These schemes use SRA-regulated solicitors so consumer protection is identical to a paid will. The trade-off: charity legacy is suggested (not required for Free Wills Month) — most participating donors do leave at least 1% of estate. Donations to UK charities are 100% IHT exempt and reduce the IHT rate from 40% to 36% on the rest of the estate where charity legacy is 10%+ of the net estate (Schedule 1A IHTA 1984).

14. Inheritance Tax planning through wills

The will is the single most important IHT planning document. Structured correctly it can save tens of thousands in IHT. Key planning levers:

• RNRB qualification: ensure family home passes to direct descendants (not via trust unless IPDI / Bereaved Minor / 18-25 / Disabled Person's Trust)
• Spouse exemption: unlimited transfers between spouses / civil partners (UK-domiciled)
• Charitable 10% rule: 10%+ of net estate to charity drops IHT rate from 40% to 36% (Schedule 1A IHTA 1984)
• Two-year discretionary trust + s.144 appointment: maximum flexibility
• NRB legacies: gift up to £325,000 free of IHT to anyone
• Annual exemptions and small gifts: ensure used during life
• BPR / APR transitional: shifting business / agricultural property within £1m cap from April 2026
• Pension nomination: pension death benefits typically outside estate (subject to changes from April 2027 per 2024 Budget)
• Life policies in trust: pay outside estate, ensure DPA/Inheritance Act notice given
• Equalising estates between spouses: maximise both NRB and RNRB

For an estate of £2 million with married couple — properly structured will (mirror with descendant home gift) can shelter £1 million via combined NRB + RNRB at 0%, then 40% applies to £1 million = £400,000 IHT (vs £670,000 in worst case without planning). Saving of £270,000 illustrates why the solicitor's £500-£1,500 fee for a structured will is exceptional value.
