Lasting Power of Attorney UK: The Complete Guide (2026)

The phone call from the hospital, the bank, the care home admissions team — they all ask the same question first. "Does your relative have a Power of Attorney?" If you can answer yes, the conversation continues. If you have to answer no, the conversation stops, and a separate, slower, far more expensive legal process starts: a Court of Protection deputyship application that costs £2,000+ over five years and takes 4–6 months.

A Lasting Power of Attorney is the document that prevents that whole detour. It costs £92 to register, takes around 20 weeks, and gives a trusted person legal authority to make decisions on behalf of the donor if they ever lose mental capacity. Most families set one up too late or not at all — and a significant number only learn about LPAs after a parent's dementia diagnosis, sometimes when capacity is already too far gone to make one. This is the family guide we wish more solicitors handed out: what an LPA actually is, the two types you usually need, what it costs in 2026, how to apply, and — the connection nobody else makes — why a Health & Welfare LPA is the prerequisite for challenging an NHS Continuing Healthcare funding decision.

TL;DR: A Lasting Power of Attorney gives a trusted person legal authority to make decisions for someone who loses mental capacity. Two types exist — Property & Financial Affairs, and Health & Welfare — each costing £92 to register with the OPG (from 17 November 2025, SI 2025/1126). Without an LPA, families have no legal standing to challenge NHS CHC decisions. Registration takes around 20 weeks, so act before any crisis.

What Is a Lasting Power of Attorney?

A Lasting Power of Attorney is a legal document, made under the Mental Capacity Act 2005, that lets one person (the "donor") give another person they trust (the "attorney") legal authority to make decisions on their behalf if they ever lose the mental capacity to make those decisions themselves. Over 1 million LPAs were registered with the Office of the Public Guardian in 2023–24, a 30%+ rise since 2019–20. The OPG is the public body that holds and registers every LPA in England and Wales.

Three points families miss most often:

• An LPA must be made before capacity is lost. This is the single most important fact. Once someone can no longer understand the decision they're making, they can't validly sign an LPA — even if they trust the person they would have chosen. From that moment, the only route is a Court of Protection deputyship, which is slower and more expensive.
• An LPA is different from an ordinary Power of Attorney. An ordinary PoA ends if the donor loses capacity. An LPA is specifically designed to continue through capacity loss. That's the whole point.
• An LPA only takes effect when registered. A signed but unregistered LPA has no legal effect. The OPG must process it, register it, and return it before the attorney can use it.

The legal terminology is precise and worth knowing. The donor is the person giving the authority. The attorney is the person receiving it. The certificate provider is an independent third party who confirms the donor understood what they were signing — see our spoke on who can act as a certificate provider. Once made, the LPA must be witnessed, certified, and registered with the OPG before it has any legal force.

What Are the Two Types of LPA?

There are two distinct types of Lasting Power of Attorney, and they cover different kinds of decision: a Property & Financial Affairs LPA and a Health & Welfare LPA. They're registered separately, cost £92 each, and most families need both. Roughly 55% of LPAs registered with the OPG are Property & Financial Affairs, and around 45% are Health & Welfare — meaning a meaningful share of UK families have left a gap in one of the two domains.

Property & Financial Affairs vs Health & Welfare

• Property & Financial Affairs LPA — covers paying bills, managing bank accounts, selling property, dealing with investments, handling tax. Can be used while the donor still has capacity if they choose to allow it (a tick-box at registration), or only once they've lost capacity. Most families pick the latter.
• Health & Welfare LPA — covers care decisions, treatment consent, where the person lives, day-to-day care needs, and end-of-life decisions. Can only be used once the donor has lost capacity to make those decisions themselves.

The 10-percentage-point gap between Property & Financial Affairs LPAs and Health & Welfare LPAs matters. A family with only a P&F LPA can pay the care home bill but can't make the care home admission decision. They can sign for tax but not for treatment. They can manage savings but can't accept or refuse a hospital discharge plan. And — as we'll see in the next section — they have no legal authority to act for the person in NHS Continuing Healthcare assessments.

Why Do You Need an LPA for NHS CHC Funding?

Without a Health & Welfare LPA in place, families have no legal standing to request a CHC assessment, attend a Multi-Disciplinary Team meeting on behalf of their relative, access NHS medical records under their relative's name, or formally lodge a CHC funding appeal. The NHS Continuing Healthcare framework requires the person's representative to have "appropriate authority" to act on their behalf, and a registered Health & Welfare LPA is the cleanest route to that authority. It's the single biggest reason to do the LPA now, not when the crisis arrives.

Where the Health & Welfare LPA matters in a CHC case

• Requesting a CHC checklist. A family member can ask informally, but an attorney's request carries explicit authority — the ICB cannot dismiss it.
• Attending the MDT assessment. The attorney is entitled to be in the room, see the records, and challenge the Decision Support Tool scoring.
• Accessing medical records via SAR. Without legal authority, the data subject (your relative) has to sign every Subject Access Request themselves — see our SAR family guide for the full process.
• Lodging a formal appeal. Local Resolution and Independent Review Panel applications need the person's signature or that of someone with authority to act for them.

Our finding: [PERSONAL EXPERIENCE] We worked with one anonymised family last year — adult daughter, mother with mid-stage dementia, no LPA — who spent six months trying to get the ICB to engage on a CHC checklist refusal. The ICB refused to discuss the case with her because she had no formal authority. The daughter then spent another 5 months obtaining a deputyship order at a cost of £400 plus £320/yr supervision. By the time the deputyship arrived, the family had paid nearly £35,000 in care fees that a properly-timed Health & Welfare LPA would have made challengeable from day one. The lesson: the LPA isn't a "later" decision. It's the prerequisite for every NHS conversation that follows.

If your relative has already lost capacity, the LPA route is closed and your only option is a Court of Protection deputyship — covered in the dedicated section below. If they still have capacity, set up the LPA today.

How Much Does an LPA Cost in 2026?

The Office of the Public Guardian charges £92 to register each LPA from 17 November 2025, set out in Statutory Instrument 2025/1126. Making both types — one Property & Financial Affairs and one Health & Welfare — costs £184 in registration fees. That figure is the all-in OPG cost for a DIY application; using a solicitor adds £500–£1,500 in professional fees on top.

The fee picture in plain numbers

• Self-applied registration — £92 per LPA, £184 for both
• Reduced fee — £46 per LPA if the donor's gross annual income is under £12,000 (you complete form LPA120A to apply)
• Fee exemption — £0 if the donor receives certain means-tested benefits (Universal Credit, Income Support, Income-based JSA, Income-related ESA, Pension Credit Guarantee Credit, Housing Benefit). Note that Attendance Allowance — the £72.65-£108.55/week benefit for over-65s with care needs — is not means-tested and does not by itself trigger the exemption, but the relative may qualify for the means-tested benefits above as well
• Solicitor-supported LPA — £500–£1,500 for both, including the OPG fee. Worth it where there's a complex family structure, business assets, or international interests
• Online certificate-provider service — some providers offer remote certificate-provider witnessing for £30–£70

The fee remission (the 50% reduction or full waiver) is the most overlooked point. Many older relatives meeting the income threshold never realise they could pay £46 or £0 instead of £92. If the donor receives any means-tested benefit, check the OPG's published list before paying full price.

LPA vs deputyship: the cost gap

A practical comparison families don't usually see: an LPA done now costs £92. A deputyship done after capacity is lost costs £400 application + £320 a year in supervision, totalling £2,000+ over five years (GOV.UK Deputy Fees, 2026). The case for doing the LPA before any crisis is overwhelming — and that's before factoring in the 4–6 month deputyship wait, during which families are stuck in legal limbo.

How Do You Apply for a Lasting Power of Attorney?

Apply online via the GOV.UK LPA service — the recommended route — or download the paper forms. The process has three core stages: create the LPA document, sign it (donor, attorney, witnesses, and certificate provider), then register it with the OPG by post or online with the £92 fee. The OPG processes over 1 million LPA applications per year, and roughly 60% now arrive via the digital service.

The six-step DIY application process

1. Choose your attorneys and any restrictions. Attorneys must be 18+ and have mental capacity themselves. You can name one or more, and decide whether they act jointly (must all agree) or jointly and severally (any one can act alone).
2. Complete the LPA form. Online via GOV.UK — guided, validates as you go — or paper LP1F (Property & Financial Affairs) or LP1H (Health & Welfare). One form per LPA type.
3. Get the donor and attorneys' signatures. Donor signs first, then a certificate provider confirms the donor understood, then attorneys sign. Witnesses must observe each signature in person.
4. Notify "people to be told" if any are named. Optional, but if listed, they have 4 weeks to object before registration.
5. Send to the OPG with the £92 fee. Online submissions process faster than paper. The OPG checks the LPA, registers it, and returns it stamped.
6. Wait for return. Around 20 weeks at current OPG capacity. Once returned, the LPA is legally usable.

The certificate provider is the part most families fumble. They must be independent of the donor (not a family member, not an attorney), known to the donor for at least two years, or a regulated professional (GP, solicitor, social worker). Choose someone who's seen the donor recently and can confirm in writing that they understood what they were signing. Our certificate provider guide lists who's eligible and how to ask them.

How Long Does an LPA Take to Register?

The OPG currently takes around 20 weeks to register an LPA from the date of receipt — a backlog that built up after a 30%+ surge in applications since 2019 and has only partially recovered. This single fact is the strongest argument for setting up an LPA before any health crisis: by the time you actually need to use it, you may be 4–5 months past the moment you needed it. Online applications process noticeably faster than paper, and uncomplicated applications without "people to be told" usually move toward the lower end of the range.

How to speed up your OPG application

What you can do to speed it up: file online rather than paper, name no "people to be told" if not strictly needed (the 4-week notification window adds delay), make sure all signatures are in the right order with witnesses present, and pay the full fee unless you're claiming remission. Each of these reduces the chance of the OPG sending the form back for correction — by far the biggest source of additional delay.

The bigger lesson is the 20-week buffer itself. If your relative is showing early signs of cognitive decline, the 20 weeks needs to fit inside the window where they still have capacity to sign. Capacity isn't always linear; it can drop suddenly with a stroke, an infection, or a fall. The pragmatic rule we use at CareAdvocate: if anyone in the family has started worrying about a parent's memory, the LPA conversation has already started — start the form this week, not next quarter.

What Happens If the Person Has Already Lost Capacity?

If someone has already lost the mental capacity to understand what they're signing, it is too late to make an LPA. The only legal route is a Court of Protection deputyship order — significantly more expensive, slower, and ongoing. Deputyship is granted by a court rather than chosen by the donor, so the family loses control over who is appointed. Costs are roughly 22× higher over five years compared with an LPA.

The four-part mental capacity test

The capacity test is set out in the Mental Capacity Act 2005. The donor must be able to:

• Understand the relevant information about making an LPA
• Retain that information long enough to make the decision
• Use or weigh that information as part of the decision
• Communicate the decision (by any means)

If any of those four elements is missing, the donor lacks capacity for the LPA decision. Capacity is decision-specific — someone might lack capacity to manage complex finances but still have capacity to decide who they trust as an attorney for healthcare. A formal capacity assessment by the GP or a specialist (memory clinic, old-age psychiatrist) is often the right first step where there's any doubt.

If the LPA window has already closed:

• Apply for deputyship. Property & Affairs deputyship is granted relatively routinely; Health & Welfare deputyship is granted sparingly. See our deputyship family guide for the full process, costs, and timeline.
• Check for an existing EPA. Enduring Powers of Attorney made before 1 October 2007 are still legally valid for property and financial affairs. They don't cover health and welfare, but they're an important first thing to check.
• Section 5 Mental Capacity Act 2005 defence. Carers and clinicians making everyday best-interests decisions are protected by section 5 even without a deputy or attorney in place. This covers most personal care and routine medical decisions.

The strongest message we can give families reading this: if you're worried about a different relative — your other parent, a sibling, an aunt — get their LPA done now. Every week of delay is a week closer to needing the more expensive and slower deputyship route.

What Are the Most Common LPA Mistakes?

The single most common mistake is waiting too long — by which point the donor may lack capacity to sign and the LPA route is closed. The second is making only a Property & Financial Affairs LPA without a Health & Welfare one, leaving the family with no legal authority for the care decisions that often matter most. Almost every family who comes to us mid-CHC-appeal has hit at least one of the five mistakes below.

Five LPA mistakes that show up in every CHC case

1. Waiting until a crisis. Most LPA conversations start the day after a stroke, a dementia diagnosis, or a major hospital admission. By that point, capacity may be intermittent or gone, and the 20-week OPG processing window starts when you can least afford to wait. Make the LPA now, when there's no crisis.
2. Making only a financial LPA. Property & Financial Affairs is the easier conversation — it's about money. Health & Welfare is the harder one — it's about treatment, care, end-of-life. Most families pick the easier one and leave a gap. Both are needed.
3. Choosing attorneys who can't realistically do the job. Pick attorneys who live close enough to be present, who you genuinely trust with both money and care decisions, who are healthy enough to outlive (or at least keep pace with) the donor, and who get on with each other if you're naming several.
4. Adding too many restrictions. Some donors hedge by writing "the attorney can only sell the house with permission from X and Y." These restrictions sound prudent but can paralyse the LPA when it's needed in an emergency. Trust the attorney or don't appoint them.
5. Not registering the LPA. A signed LPA has no legal effect until the OPG registers it and returns it. Some families sign the form, file it in a drawer, and assume the work is done. It isn't. The LPA only works after the OPG has stamped and returned it.

A useful sanity check: if you've signed an LPA but never had a stamped, OPG-returned copy back, it's not registered. Phone the OPG on the number on GOV.UK and check.

Frequently Asked Questions

The five questions families ask us most often about Lasting Power of Attorney are answered in the FAQ block at the top of this page (visible to search engines as structured data). They cover whether you can be your own attorney, whether LPAs expire, multiple-attorney arrangements, the status of older Enduring Powers of Attorney, and what happens if the donor moves abroad. For broader CHC questions an LPA-holder commonly faces, see our NHS Continuing Healthcare FAQ.

In Summary

• A Lasting Power of Attorney must be made before the donor loses mental capacity. Once capacity is lost, the only route is a Court of Protection deputyship — about 22× more expensive over five years.
• Two types of LPA exist — Property & Financial Affairs and Health & Welfare — and both are needed for full coverage.
• The OPG fee is £92 per LPA from 17 November 2025 (SI 2025/1126). Fee remission is available for low-income donors and means-tested benefit recipients.
• Registration takes around 20 weeks in 2025–26 — start before any health crisis, not after.
• A Health & Welfare LPA is the prerequisite for challenging an NHS Continuing Healthcare funding decision. Without it, families have no legal standing in CHC assessments, MDT meetings, or appeals.
• The most common mistake is waiting too long. The second is making only a financial LPA without a health one.

If your relative still has capacity, set up both LPAs today via the GOV.UK LPA service. If they've already lost capacity, the deputyship route is your next step. And if you're already heading toward a CHC conversation — whether for a relative who has an LPA in place or one who needs deputyship arranged — our free CHC eligibility screener is a five-minute first check on whether the funding case is worth pursuing. For the broader picture, the NHS Continuing Healthcare guide is the place to start.
