Medical Power of Attorney UK (2026): Does It Exist & What You Need Instead

No — England and Wales does not have a legal document called a 'medical power of attorney'. This term is used in several other countries (notably the United States and Canada) but it has no direct equivalent in English and Welsh law. The term can cause significant confusion for people who are researching healthcare planning documents. The closest English law equivalent is the Health and Welfare Lasting Power of Attorney (H&W LPA). Here is what you need to know: (1) Why there is no 'medical POA' in England and Wales: the Mental Capacity Act 2005 created a comprehensive framework for decision-making when a person lacks mental capacity. This framework uses two instruments — the Lasting Power of Attorney and the Advance Decision to Refuse Treatment. Parliament deliberately did not create a standalone 'medical power of attorney'; instead, healthcare decision-making authority is part of the broader Health and Welfare LPA; (2) What other countries mean by 'medical power of attorney': in the United States, a medical power of attorney (also called a healthcare proxy or healthcare durable power of attorney) is a specific legal document that appoints someone to make medical decisions. In Canada and Australia, similar documents exist under various names (enduring power of attorney for health, healthcare directive with proxy). These instruments are the equivalent of England and Wales's H&W LPA; (3) What to do if you have a non-UK medical POA: if you have a medical power of attorney from another country and you are now resident in England and Wales, that document does not automatically authorise your named attorney to make decisions in England and Wales. You should register an H&W LPA under the Mental Capacity Act 2005 to give your chosen attorney clear legal authority; (4) Enduring Power of Attorney (EPA): the EPA was the predecessor to the LPA but was abolished for new applications in October 2007. EPAs only covered property and financial affairs — they did not cover healthcare or welfare decisions. There has never been an EPA equivalent for healthcare in England and Wales.

The Health and Welfare Lasting Power of Attorney (H&W LPA) is a legal document registered with the Office of the Public Guardian (OPG) that authorises one or more named attorneys to make health and welfare decisions on your behalf — but only when you lack the mental capacity to make those decisions yourself: (1) What the H&W LPA can authorise: (a) day-to-day welfare decisions: where you live (including care home placement); your diet and daily routine; what you wear; social activities and recreational choices; (b) medical treatment decisions: consent to or refusal of proposed medical treatments; choices between treatment options; which NHS Trust or hospital provides your care; choices between care providers; (c) life-sustaining treatment: if you specifically grant this power, your attorney can consent to or refuse life-sustaining treatment on your behalf. This is a separate box on the LPA form that you must tick to give this authority. Without ticking the box, attorneys cannot make life-sustaining treatment decisions; (2) What the H&W LPA cannot authorise: (a) financial and property decisions — these require a separate Property and Financial Affairs LPA; (b) deprivation of liberty (unless the Court of Protection authorises this separately); (c) decisions contrary to an Advance Decision to Refuse Treatment made by the donor with capacity (if the ADRT is valid and applicable, it takes precedence over the attorney's decision); (3) When the H&W LPA activates: the H&W LPA can only be used when the donor lacks the capacity to make the specific decision in question — it cannot be used while the donor has capacity, unlike the Property and Financial Affairs LPA which can be used with the donor's consent even while they have capacity; (4) Key requirement — registration: the H&W LPA must be registered with the OPG before it can be used. It cannot be used immediately after signing — the registration process typically takes 20+ weeks in 2026. Register early, while you have capacity.

Registering a Health and Welfare LPA in England and Wales involves several steps: (1) Create the LPA document: you can use the OPG's online service at register-lasting-power-of-attorney.service.gov.uk (faster) or complete the paper form LP1H. The document must be: (a) signed and dated by the donor; (b) signed by a certificate provider (a person who confirms the donor understands the LPA and is not being pressured — this can be a GP, solicitor, social worker, or other qualified professional; not a relative or attorney); (c) signed by each attorney; the registration fee paid (£82 per LPA in 2026 — unchanged since 2017); (2) Registration process: submit the signed LPA to the OPG (online or by post to OPG, PO Box 16185, Birmingham, B2 2WH). The OPG processes the application and registers the LPA. The OPG writes to the donor and all named attorneys. Current OPG processing times (2026): online applications: typically 4–10 weeks; paper applications: 4–16 weeks. The OPG can check the ID of the donor and attorneys as part of its fraud prevention process; (3) Fee reduction and exemption: the £82 registration fee is reduced to £41 for those whose gross income is below £12,000 per year. The fee is waived entirely for those receiving means-tested benefits (income-related ESA, income-based JSA, Income Support, Universal Credit with net income below £12,000, Pension Credit, or NHS Low Income Scheme HC1 certificate). Apply using form LPA120A; (4) After registration: the OPG stamps and returns the original registered LPA. The original must be produced (or a certified copy) every time the attorney wishes to use it. Healthcare providers, banks, and other organisations will want to see the original or a copy certified by a solicitor; (5) Safeguards: during registration, the OPG allows named people (if any were listed as 'people to be told') to object if they believe the LPA is invalid. Any person can raise a 'prescribed person' objection within 5 weeks. Grounds for objection include: the donor lacked capacity; the LPA was signed under undue influence; fraud.

An Advance Decision to Refuse Treatment (ADRT — also known as an 'advance directive' or 'living will') is a different document that operates alongside (or instead of) the Health and Welfare LPA: (1) What an ADRT is: an ADRT allows you to refuse specific medical treatment in advance, to take effect if you later lack capacity. It is a refusal document — you cannot use it to demand specific treatment; only to refuse specific treatment; (2) Key differences from the H&W LPA: (a) the H&W LPA appoints a person (your attorney) to make decisions; an ADRT records your own specific decisions in advance — no attorney is involved; (b) the H&W LPA must be registered; an ADRT does not require registration (though keeping a copy with your GP and hospital records is strongly advised); (c) the H&W LPA covers all welfare and healthcare decisions; an ADRT only covers the specific treatments you list; (d) a valid and applicable ADRT overrides your H&W LPA attorney — even if your attorney would make a different choice, your advance refusal must be honoured; (3) Requirements for an ADRT to be valid (Mental Capacity Act 2005 ss.24–26): (a) you must be 18 or over; (b) you must have had capacity when you made it; (c) it must be specific enough — it must state the treatment being refused and the circumstances; (d) if the ADRT includes refusal of life-sustaining treatment, it must: be in writing; be signed by you (or someone at your direction); be witnessed; include the statement 'this advance decision is to apply even if my life is at risk'; (4) The ADRT in practice: once made, share it with your GP (ask them to record it in your notes), any hospitals you use regularly, and your family. Keep it with your will or H&W LPA. Review it after any significant change in health, relationship, or circumstances; (5) Which do you need — LPA or ADRT or both? Many people benefit from having both: the H&W LPA appoints a trusted person to handle the countless decisions that cannot be anticipated in advance; the ADRT records your specific wishes about treatment scenarios you feel strongly about (end-of-life care; CPR; ventilation; artificial nutrition). They complement each other.

Scotland and Northern Ireland have their own separate legal frameworks for welfare and medical decision-making: (1) Scotland — Welfare Power of Attorney: Scotland has a legal document called a Welfare Power of Attorney under the Adults with Incapacity (Scotland) Act 2000. This is the direct equivalent of England and Wales's Health and Welfare LPA. The attorney (called the 'welfare attorney') can make decisions about personal welfare, including where the person lives and medical treatment, when the person lacks capacity. The Welfare POA must be certified by a 'prescribed person' (solicitor, medical practitioner, etc.) and registered with the Office of the Public Guardian (Scotland) at opg.scot.gov.uk. Unlike England and Wales, Scotland's welfare attorney can be used from the moment of registration — there is no requirement to wait until capacity is lost before using it (though in practice welfare decisions only become necessary once capacity is lacking). Scotland also has Advance Directives for specific treatment refusals, similar to the ADRT in England and Wales; (2) Northern Ireland — Enduring Power of Attorney: Northern Ireland has not yet fully implemented a Mental Capacity Act equivalent. As of 2026, Northern Ireland still uses the older Enduring Power of Attorney (EPA) framework under the Enduring Powers of Attorney (Northern Ireland) Order 1987. This covers financial affairs. For healthcare decisions, Northern Ireland has limited formal mechanisms — there is no direct equivalent of the H&W LPA. Healthcare professionals in Northern Ireland follow best interests principles under common law for incapacitated adults. The Mental Capacity Act (Northern Ireland) 2016 received Royal Assent but only some provisions are in force as of 2026 — a full rollout is expected but implementation has been slow; (3) Using an England/Wales H&W LPA in Scotland: an H&W LPA registered in England and Wales has no automatic legal authority in Scotland. To give your attorney authority in Scotland, you should register a separate Welfare POA under Scots law; (4) Cross-border medical treatment: if you have an English H&W LPA and receive medical treatment in Scotland, Scottish healthcare providers are not legally required to recognise it. In practice, hospitals will take it into account as evidence of your wishes but your attorney has no formal legal authority under Scots law.
