Your financial adviser needs details from an old pension provider. The provider asks for written authority before sharing anything. Now you are wondering whether you need a Letter of Authority or a Power of Attorney.
So, what is the difference between a Letter of Authority (LoA) and Power of Attorney (PoA)? A Letter of Authority usually lets someone request information or complete a specific administrative task for you. A Power of Attorney gives someone legal authority to make decisions and take action on your behalf.
For example, an adviser may use a Letter of Authority to collect pension values, charges and policy details. They cannot normally use it to withdraw money, transfer the pension or change your investments.
A Power of Attorney may allow the appointed person to manage bank accounts, pensions, investments or property. The exact powers depend on the type of document and the authority written into it.
This guide explains how both documents work, what each one allows, how mental capacity affects them, what happens if the wrong one gets submitted, and which option you may need in different situations.
What is Letter of Authority?
A Letter of Authority is written permission that lets a named person or organisation deal with a provider on your behalf. The letter should clearly state who has permission and what they are allowed to do.
In financial advice, an LoA is mainly used to access information. A client may sign one so their financial adviser can contact pension providers, insurers or investment companies.
An LoA may allow the adviser to request:
Current pension or investment values
Plan charges and fees
Fund information
Contribution records
Transfer values
Exit penalties
Guaranteed or protected benefits
Copies of policy documents
The authority is limited to what the letter allows. It does not normally let the adviser withdraw money, transfer a pension, change investments or make financial decisions for the client.
The Pension Protection Fund gives a useful real-world example. It states that its LoA lets someone request and receive information. But it does not allow that person to make changes or decisions for the pension scheme member.
A Letter of Authority should not be treated as complete control over an account. It will not normally allow an adviser or family member to withdraw money, transfer a pension or change investments.
What is Power of Attorney?
A Power of Attorney (PoA) is a legal document that allows one person to appoint another person to act or make decisions for them.
The person creating the document is called the donor. The person appointed is called the attorney, although they do not need to be a solicitor.
Depending on its scope, a Power of Attorney may allow the attorney to:
Manage bank accounts
Pay bills
Deal with investments
Collect pension or benefit payments
Manage property
Complete financial transactions
Give instructions to financial providers
The attorney does not automatically receive unlimited control. Their authority depends on the type of Power of Attorney and any instructions or restrictions written into it.
1. Ordinary Power of Attorney
An ordinary Power of Attorney is usually used when someone needs temporary help managing money or property.
For example, the donor may be abroad, recovering from an illness or unable to visit their bank. The authority can cover one transaction or several financial matters.
An ordinary PoA can only be used while the donor has mental capacity. It stops working if the donor can no longer make their own decisions.
2. Lasting Power of Attorney
A Lasting Power of Attorney (LPA) is used for longer-term planning. It allows the donor to appoint one or more attorneys to help make decisions or make decisions on their behalf.
The donor must be at least 18 and have mental capacity when creating the LPA. It must also be registered with the Office of the Public Guardian before it can be used.
There are two types of LPA in England and Wales:
Property and financial affairs LPA: Covers money, bank accounts, bills, pensions, benefits and property.
Health and welfare LPA: Covers medical treatment, daily care and living arrangements.
A property and financial affairs LPA is the relevant type for pensions and investments. A health and welfare LPA does not give the attorney general authority to manage the donor’s finances.
Note: The LPA system described here applies to England and Wales. Scotland and Northern Ireland have separate Power of Attorney systems.
Letter of Authority vs Power of Attorney at a Glance
The main difference between a Letter of authority and Power of Attorney is the level of authority given to the representative.
An LoA usually supports access to information or a defined administrative task. A PoA may give someone formal legal authority to act or make decisions within the document’s scope.
Area | Letter of Authority (LoA) | Power of Attorney (PoA) |
Main Purpose | Request information or complete defined tasks | Act or make decisions for someone |
Nature of authority | Written permission within a limited scope | Formal legal authority within the document’s scope |
Information Access | Usually allowed for the information listed | May be allowed if covered by the document |
Financial Decisions | Usually not allowed | May be allowed |
Access to Money | Usually not allowed | May be allowed if authorised |
Account Changes | Usually not allowed | May be allowed if authorised |
Mental Capacity | Should not be treated as authority to make decisions after capacity is lost | An ordinary PoA ends if capacity is lost; a registered LPA may continue |
Registration | No central government registration process | An ordinary PoA is not registered as an LPA; an LPA must be registered |
Typical Use in Financial Advice | Collecting pension, investment and policy information | Managing financial affairs or giving instructions for the donor |
The simplest way to understand the difference is information versus decisions.
An LoA usually lets someone find out what is held in an account or policy. A PoA may let them act on that information.
Letter of Authority vs Power of Attorney for Pension Advice
The difference becomes especially important when a financial adviser reviews a client’s pensions.
Before giving advice, the adviser may need to check:
Current plan values
Contributions
Fund holdings
Charges
Transfer values
Exit terms
Guaranteed benefits
Protected features
A Letter of Authority allows the adviser to request this information from the pension provider. The adviser can then review the plan and explain the available options to the client.
However, collecting information is not the same as making the decision. An LoA may allow the adviser to request a transfer value, but it does not normally allow them to approve or complete the transfer.
A client who has mental capacity and is acting for themselves does not need a Power of Attorney simply because they want to transfer or withdraw from their own pension. They can give the instruction directly, subject to advice, provider checks and scheme rules.
A Power of Attorney becomes relevant when another person must make or approve financial decisions for the pension holder. Depending on its scope, an attorney may be able to:
Manage pension income
Change payment details
Give investment instructions
Complete an authorised withdrawal
Make decisions after the pension holder loses capacity
Deal with wider financial affairs
For pension and investment decisions, the relevant authority will usually be an ordinary PoA or a property and financial affairs LPA. The provider must still confirm that the document covers the proposed action.
A document labelled "Power of Attorney" does not automatically permit every pension decision.
How Does Mental Capacity Affect an LoA or PoA?
Mental capacity means being able to make a specific decision at the time it needs to be made. A person may have capacity for one decision but not another.
A Letter of Authority should not be treated as permission to make financial decisions after the person who signed it loses capacity. It is not a substitute for an LPA.
An ordinary Power of Attorney also stops providing authority if the donor loses mental capacity. A registered property and financial affairs LPA can continue according to its terms.
The donor must have mental capacity when creating an LPA. If capacity has already been lost and no suitable LPA exists, someone may need to apply to the Court of Protection to become a deputy.
LoA or PoA: Which One Do You Need?
The right document depends on who is acting and what they need to do.
Situation | Likely Document |
An adviser needs a pension value or statement | Letter of Authority |
An adviser needs charges, fund details or transfer information | Letter of Authority |
A relative only needs permission to speak with a provider | LoA or provider-specific authority |
The client makes their own pension transfer or withdrawal decision | Direct client instruction, not a PoA |
Someone must complete a one-off financial task while the donor has capacity | Ordinary PoA may be suitable |
Someone must act on a pension or investment decision for the donor | Appropriate PoA, if its scope permits |
Someone must manage finances after the donor loses capacity | Registered property and financial affairs LPA |
Someone must make health or care decisions | Health and welfare LPA |
Using the wrong document can delay the case. If an LoA is submitted for a task that requires decision-making authority, the provider may reject it and ask for an appropriate PoA.
The reverse can also create unnecessary work. Asking a client to arrange a Power of Attorney for a simple information request adds time and complexity when an LoA may have been enough.
How 4admin Simplifies the LOA Process
Choosing the correct document is only the first step. When an LoA is needed, the advice firm still has to submit it, track the request, chase the provider and process the documents that come back.
4admin brings this work into one connected process. It helps advice firms:
Submit and track LoA requests
Manage provider communication
Automate follow-ups and chasing
Identify missing information
Analyse returned provider packs
Convert provider data into a structured format
Send clean data and documents into the firm’s CRM
Maintain clear, audit-ready case records
This reduces manual rekeying and gives administrators and advisers a clearer view of what has been received, what is missing and what needs to happen next.
4admin supports the administration around a Letter of Authority. It does not replace a Power of Attorney or give an adviser legal authority to make decisions for a client.
Bottom Line
To sum up, a Letter of Authority is usually enough when someone only needs access to information or permission to handle a specific task. A Power of Attorney is needed when they must manage money, approve transactions or make decisions on another person’s behalf.
The right document depends on the action required and whether the person still has mental capacity. Check the scope before sending it to a provider, as using the wrong authority can delay the case.
Frequently Asked Questions
What is the main difference between a Letter of Authority and a Power of Attorney?
An Letter of Authority (LoA) allows someone to request specific information on your behalf. A Power of Attorney (POA) allows someone to make legal or financial decisions on your behalf. Only a POA grants decision-making power.
Is a Letter of Authority a type of power of attorney?
No. They are separate forms of authority. An LoA usually gives limited permission, while a PoA can give formal legal authority to act and make decisions.
Can a financial adviser make decisions with an LoA?
Usually not. An adviser may use an LoA to collect information and communicate with providers, but the client or an authorised attorney normally makes the financial decision.
Can someone withdraw money with a Letter of Authority?
An information-only LoA does not normally allow withdrawals. The provider would need evidence that the person has specific authority to access or manage the money.
Does a Power of Attorney give someone complete control?
No. An attorney can only act within the powers included in the document. The donor may also add instructions or restrictions.
Does a Power of Attorney Continue After Mental Capacity Is Lost?
An ordinary PoA does not. A registered LPA can continue according to its terms.
Can an adviser hold an LoA while an attorney makes decisions?
Yes. The adviser may use an LoA to collect information while an attorney makes decisions under a valid PoA. The provider should check the scope of both documents before sharing information or accepting instructions.
