A Letter of Authority can expire. But there is no single expiry rule that applies to every provider, product, or financial advice firm. 

In practice, most LoAs are treated as valid for a fixed period. A common timeframe is 12 months from the date the client signs it, but some providers may apply shorter rules. 

For advice firms, the real issue is not only whether the LoA has expired. The bigger issue is whether the provider will still accept it, whether the authority still matches the request, and whether the firm can evidence that the client gave valid permission. 

This blog explains how LoA expiry works in the UK, why provider rules differ, and how advice firms can avoid delays caused by expired or outdated Letters of Authority. 

Does a Letter of Authority Expire?

Yes, a Letter of Authority can expire. 

However, the UK does not have one fixed statutory rule saying every LoA expires after a specific number of months. The validity usually depends on the wording of the LoA and the provider’s own acceptance rules. 

In many financial advice workflows, a 12-month period is treated as common practice. But some providers may require a more recent signature, such as one dated within the last 6 months. 

This means advice firms should not assume that every provider will accept the same LoA for the same length of time. 

How Long is a Letter of Authority Usually Valid for?

A Letter of Authority is often valid for 12 months from the date it was signed. 

That is the common position many firms use when managing LoA workflows. It also gives admin teams a simple benchmark for tracking expiry dates. 

But this should not be treated as a universal rule. 

Some providers may apply a shorter validity period. For example, Standard Life says Letters of Authority or Change of Agency requests must be signed and dated by the planholder and be less than six months old.  

Other providers may accept authority for longer if the LoA clearly states that it remains valid until revoked. Some ongoing servicing arrangements may also continue until the client cancels or replaces the authority. 

So the safest answer is this: 

A Letter of Authority usually lasts for the period stated in the document, but provider rules decide whether it will be accepted in practice. 

Is 12 Months a Legal Rule

No, 12 months is not a fixed legal expiry rule for every LoA. 

It is better understood as a common industry practice. It is often used because it creates a clear control point for reviewing whether the authority is still current. 

The ICO also explains that UK GDPR does not set a specific time limit for consent. How long consent lasts depends on the context, and consent may need to be reviewed or refreshed when appropriate.  

That matters because an LoA often involves access to client information. If the authority is old, unclear, or no longer matches the original purpose, relying on it can create operational and compliance risk. 

When Does the LoA Validity Period Start

LoA validity normally starts from the signature date. 

This is an important point because some firms confuse the signature date with the submission date. The provider usually checks when the client signed the document, not when the adviser uploaded or emailed it. 

For example, if a client signs an LoA on 1 January but the firm submits it to the provider on 1 March, the validity period usually starts from 1 January. 

This matters when teams delay submission, store LoAs in inboxes, or wait until later in the advice process before contacting providers. By the time the request is sent, part of the validity window may already be gone. 

Why Providers Reject Older LoAs?

Providers reject older LoAs for several reasons. 

The first reason is risk control. Providers need to be confident that the client still wants the adviser or advice firm to access their information. 

The second reason is data protection. Providers are cautious about releasing personal or policy information without clear and current authority. 

The third reason is internal policy. Some providers have their own rules around signature age, format, wording, or servicing authority. 

This is why two providers may treat the same LoA differently. One may accept it, while another may ask for a fresh document. 

Expiry Date vs Signature Age vs Revocation

Advice firms should understand the difference between expiry date, signature age, and revocation. These terms are connected, but they do not mean the same thing. 

This distinction is important for workflow control. A document may not show an expiry date, but the provider may still reject it because the signature is too old. In the same way, a document may still be within 12 months, but it should not be used if the client has withdrawn authority. 

Can a Letter of Authority Stay Valid Until Revoked?

Yes, some LoAs can be drafted to remain valid until revoked. 

This means the authority continues until the client cancels it in writing or a new instruction replaces it. This can be useful for ongoing servicing relationships where the adviser needs continued access to provider information. 

However, “valid until revoked” does not guarantee that every provider will accept the LoA forever. 

Some providers may still apply their own signature-age rules. Others may ask for a refreshed authority if the request is new, sensitive, or outside the original scope. 

For advice firms, this creates a practical rule: even if the LoA wording is open-ended, the provider’s acceptance process still matters. 

Can a Client Cancel a Letter of Authority?

Yes, a client can usually cancel a Letter of Authority. 

This is normally done by giving written notice to the adviser, provider, or both. Once the client withdraws authority, the firm should no longer use that LoA to request information. 

The ICO also states that people have the right to withdraw consent, and organisations need proper withdrawal procedures in place.  

For advice firms, this means revocation should not sit in an inbox or informal note. It should be recorded clearly inside the workflow or CRM so teams do not chase providers using cancelled authority. 

What Happens When an LoA Expires?

When an LoA expires, the provider may stop processing the request. 

This can delay onboarding, pension reviews, consolidation work, replacement business, or annual planning. The adviser may then need to go back to the client for a new signature. 

The impact is often bigger than it looks. 

An expired LoA can create: 

• Provider rejection  

• Duplicated admin work  

• Extra client chasing  

• Delayed policy information  

• Slower suitability analysis  

• Missed review timelines  

• Weaker audit trail visibility  

This is why LoA expiry is not just a document issue. It is a workflow issue. 

Why LoA Expiry Creates Problems for Advice Firms

LoA expiry becomes difficult when firms manage requests manually. 

In many advice firms, LoAs are still tracked through email inboxes, spreadsheets, provider portals, and individual staff reminders. This makes it easy for expiry dates to be missed. 

The problem grows as LoA volume increases. 

A single client may have several pensions, investments, and insurance policies across different providers. Each provider may have different requirements and response times. 

If even one LoA expires during the process, the whole case can slow down. 

This creates pressure on admin teams, paraplanners, and advisers. It also creates frustration for clients who may not understand why they are being asked to sign another document. 

LoA Expiry and Client Experience

Clients usually see the LoA as a simple signature. 

They may not understand that each provider has its own rules, timelines, and checks. So when a firm asks them to sign a fresh LoA, it can feel like repetition or poor organisation. 

This matters because client trust is shaped by small operational moments. 

If the client has already signed once, they may expect the firm to handle the rest. When the process breaks because an LoA expired, the client may see the delay as an internal failure.

FCA Consumer Duty also places focus on good customer outcomes, including acting in good faith, avoiding foreseeable harm, and supporting customers to pursue their financial objectives.  

That does not mean every expired LoA is a Consumer Duty breach. But it does mean firms should manage avoidable friction carefully, especially when delays affect advice delivery. 

When Should an Advice Firm Request a New LoA?

A firm should request a new LoA when the existing authority is no longer safe, clear, or acceptable. 

This is usually needed when: 

• The LoA has passed its stated expiry date  

• The provider requires a newer signature  

• The client has changed adviser  

• The request goes beyond the original authority  

• The product or provider has changed  

• The client has withdrawn authority  

• The document is missing key client or policy details  

• The original LoA cannot be located  

• The provider has rejected the document  

A new LoA may also be sensible when a case has been inactive for a long period. 

Even if the previous LoA has not formally expired, the firm should ask whether the authority still reflects the client’s current intention. 

Should Every LoA Include an Expiry Date?

In most cases, yes. 

A clear expiry date helps the client, adviser, provider, and admin team understand how long the authority is meant to last. It also reduces confusion when the document is reviewed later. 

An LoA should ideally state: 

• Who is giving authority 

• Who is authorised  

• What information can be requested  

• Which provider or policy it relates to  

• When the authority starts  

• When the authority ends  

• How the client can revoke it  

This does not need to make the document complicated. In fact, clear wording usually makes the LoA easier to accept. 

Why Provider Rules Matter More Than Assumptions?

Advice firms should not rely only on a standard internal LoA template. 

A template can help create consistency, but it does not remove provider variation. Some providers may need specific wording, identifiers, forms, or signature rules. 

This is one reason LoA processes fail after submission. 

The document may look complete internally, but the provider may still reject it because it does not match their requirements. 

This is also why provider requirement tracking is important. Firms need visibility over which providers accept which LoA format, how long signatures remain valid, and when fresh authority is needed. 

How to Track LoA Expiry Properly?

LoA expiry should be tracked as part of the workflow, not as a side note. 

At minimum, advice firms should record: 

• Client name  

• Provider name  

• Policy or account reference  

• Date signed  

• Date submitted  

• Expiry date  

• Authority type  

• Current status  

• Last chase date  

• Rejection reason, if applicable  

This information helps teams see which LoAs are active, which are close to expiry, and which need client action. 

It also makes reporting easier for managers. Instead of relying on inbox searches, they can see the status of LoA work across the firm. 

Common LoA Expiry Mistakes

Many LoA expiry issues are caused by simple process gaps. 

Common mistakes include: 

• Using the submission date instead of the signature date  

• Forgetting to record the expiry date  

• Assuming all providers accept 12-month LoAs  

• Using old authority for a new request  

• Relying on an LoA after the client has changed adviser  

• Failing to track provider-specific validity rules  

• Leaving rejected LoAs unresolved  

• Not informing the client early about possible delays  

These errors are small individually. But across a growing advice firm, they can create serious operational drag. 

How Expired LoAs Affect Back-Office Efficiency?

Expired LoAs create rework.

Admin teams may need to contact the client again, prepare a new document, collect a fresh signature, resubmit the request, and restart provider chasing. 

This increases time per case. It also reduces first-time-right performance. 

In a busy firm, that rework can spread across the whole back office. Paraplanners wait for missing policy data. Advisers wait for analysis. Clients wait for updates. 

So the cost of an expired LoA is not just the time spent fixing one document. It is the delay it creates across the advice process. 

How 4admin Helps Firms Manage LoA Expiry?

4admin helps advice firms bring structure and visibility into the LoA process. 

Instead of tracking LoAs across emails and spreadsheets, firms can centralise the workflow and monitor where each request sits. This makes it easier to see which LoAs are submitted, outstanding, rejected, or approaching expiry. 

4admin supports firms by helping with:

• LoA submission and tracking  

• Provider follow-ups  

• Workflow visibility  

• Document handling  

• Data extraction from provider responses  

• CRM-ready outputs  

• Clearer operational oversight  

This does not remove human control from the process. It gives teams better visibility, so they can act before small LoA issues become case delays. 

For firms dealing with pensions, investments, and provider-heavy onboarding, this can make a noticeable difference to operational capacity. 

Bottom Line: LoA Expiry is a Workflow Control Issue

A Letter of Authority can expire in the UK, but the exact timeframe depends on the document wording and the provider’s own rules. 

A 12-month period is common, but it is not universal. Some providers may require a more recent signature, while some ongoing authorities may remain valid until revoked. 

For advice firms, the safest approach is to treat LoA expiry as a workflow control. 

That means recording the signature date, tracking provider rules, monitoring expiry dates, and refreshing authority before it delays the case. 

The firms that manage this well do not wait for providers to reject old LoAs. They build expiry checks into the process from the start. 

If your firm is still managing LoAs through inboxes, spreadsheets, and manual reminders, expired authority may already be creating hidden delays in your advice process. 

Frequently Asked Questions

How long is a Letter of Authority valid for?

A Letter of Authority is often treated as valid for 12 months from the signature date. However, some providers may require a newer signature, such as one dated within the last 6 months. 

Is there a legal 12-month expiry rule for LoAs?

No, there is no single legal rule saying every LoA expires after 12 months. It is a common industry practice, but provider rules and the wording of the LoA matter most. 

Can an LoA remain valid until revoked?

Yes, some LoAs can remain valid until the client revokes them. However, providers may still apply their own rules before accepting the document. 

What happens if an LoA expires?

The provider may reject the request or ask for a fresh LoA. This can delay onboarding, pension reviews, transfer analysis, or other advice work. 

When should an advice firm request a new LoA?

A new LoA should be requested when the old one has expired, the provider requires a newer signature, the client changes adviser, the scope changes, or the client has withdrawn authority. 

How can advice firms avoid expired LoA delays?

Advice firms can avoid delays by tracking signature dates, expiry dates, provider rules, submission status, and rejected requests inside a central workflow system. 

Does LoA expiry affect client trust?

Yes, it can. If clients are asked to sign the same type of document again because the first LoA expired, they may see the process as slow or disorganised.
