- With cybercrimes reaching a peak, financial institutions are 300 times more likely to be affected than any other company, per Clodive.
- Banks and financial institutions need to collect proof of address for employee verification, supplier onboarding, and business account beneficial owners – not just retail customers.
- Most institutions are still handling address verification through email submissions and manual staff review, creating 2-5 day processing delays.
Been getting a few questions lately about which documents actually count for address verification. Utility bills, obviously. Council tax statements. Bank letters. But what about timing – how recent do they need to be? And when exactly do you need them anyway?
Plus, there’s always someone asking whether it’s worth switching to automated verification or sticking with the manual process.
Figured it was worth putting together a complete guide that covers all of this.
So, nothing earth-shattering below, just everything you need to know in one place: what documents work, when you actually need proof of address, how verification works whether you’re doing it manually or through tech, and what options are out there if you’re thinking about automating.
Let’s start with nuts-and-bolts.
What is Proof of Address in the UK?
A proof of address (POA) is official evidence reflecting the identity of a company in correspondence with a specific UK address. Too heavy to understand? Wait, let me explain it to you in easy terms.
POA is a document that confirms the place of business.
The main motto we have in this process is to prevent money laundering and identity theft. All regulated entities, like banks, fintechs, insurers, and investment platforms, verify their customers’ addresses before offering services.
If I were to describe UK address verification rules in one word, it would be “layered.” There are a lot of regulatory acts that govern address compliance:
- JMLSG Guidance: It spells out which documents count as valid proof, like bank statements, council tax letters, and so on.
- MLR 2017 (Money Laundering Regulations): Tells how to verify a customer’s identity and address before starting a business relationship.
- HMRC KYC: If you are dealing with international clients, HRMC expects customer due diligence measures to be followed.
- FCA Handbook (SYSC 6.3): Tells how to prevent financial crimes through reliable verification processes.
You don’t need to memorise all this. But what I’ve learnt is that if you keep these rules in mind from the start, everything runs smoothly.
Which Documents are Used as Proof of Address in Banks and Financial Institutions?
By now, I hope you understand that address proof for business is a non-negotiable part of most regulated onboarding processes.
Below is a list of documents that banks and financial institutions need to collect..
- Utility bill (gas, water, electricity, landline) – dated within the last 3 months
- Bank or credit card statement – must show transactions and be recent (usually 3–4 months)
- Council tax bill – accepted if issued within the last 12 months.
- Valid UK driving licence – only if not already used as ID
- National Health Service (NHS) letter – not older than 3 months
- Tenancy agreement – signed, dated, and ideally from a known housing provider.
- HMRC tax letter or notice – dated within the last year
- Mortgage statement (UK/EU/EEA) – issued within the last 12 months.
- Statements from a credit union or building society – must be official and recent.
How to Get Proof of Address When You’re New to the UK?
You may ask – what about newcomers in the UK? Not everyone is walking in with a utility bill in their business name. This trip up directors and founders looking to verify their business partners or vendors. Also, those setting up shop in the UK for the first time. Worry not.
Here are a few workarounds that can help:
| Document | Who it helps | What to check |
| Employer letter | New hires or relocating execs | Must be dated, signed, and on official letterhead |
| University letter | Founders or directors enrolled in UK schools | Should clearly state full name and residential address |
| Commercial lease | Businesses renting office space | Include company name, complete address, and lease term |
| Companies House registration + utility setup | UK-registered entities are still setting up operations | Alone, it’s not enough. Pair with a utility confirmation |
When do Banks and Financial Institutions Need Proof of Address in the UK?
As said earlier, mainly, you need to verify that all your partners, customers, and vendors are operating a legitimate business from a real location and not some shell company.
-
Customer Onboarding
Standard practice, but the acceptable documentation list is broader than many teams use. Utility bills are the default, though council tax statements and bank statements work just as well. The three-month timeframe is fairly standard across most institutions.
-
Employee Onboarding
Often handled by HR as routine employment verification, but compliance teams should be aware that this creates the same documentation requirements as customer onboarding. Audit trails need to be consistent across both processes.
-
Business Banking
More complex than personal accounts since you’re verifying multiple addresses – registered business location, trading addresses, and director residential addresses. Commercial teams sometimes need support in understanding which documents satisfy which requirements.
-
Onboarding Suppliers and Vendors
Third-party risk assessments now include address verification as standard practice. What used to be basic vendor management has expanded to include the same verification standards applied to customer relationships.
Most institutions have established processes, but implementation tends to vary between departments. Retail banking, commercial banking, and investment services often interpret the same requirements differently, which can create inconsistencies during regulatory reviews.
How Do Banks and Financial Institutions Verify Addresses?
Address verification hasn’t changed as much as you’d think over the past decade. Most institutions still rely on two main approaches, though the balance between them is shifting.
-
Manual Verification Process
The traditional route involves collecting documents through whatever channel works – email attachments, postal mail, in-person submissions, or basic digital upload forms.
From there, someone in operations manually checks each document against the application details, verifies it’s recent enough, and confirms it looks legitimate. It’s time-consuming but thorough, especially for edge cases that don’t fit standard patterns.
-
Technology-Enabled Verification
The newer approach captures documents digitally and runs them through OCR to pull out the relevant details automatically. AI systems then cross-check the extracted information against databases and flag anything that doesn’t match up.
Most institutions still have humans review flagged cases, but the bulk of straightforward verifications happen without manual intervention.
I suppose we are already on the same page that manually reviewing address documents is no longer effective. Automation is the obvious answer today. So let’s explore some solutions now.
Which Solutions are Available to Automate Proof of Address Verification?
The address verification space has several players, each taking different approaches to solve the same basic problem. Here’s how the main options stack up:
- Signzy: Our platform handles end-to-end address verification with global document support and real-time validation. We’ve built APIs that work across 240+ countries and integrate with existing banking infrastructure without requiring major system overhauls. The scalability piece was designed from day one to handle enterprise-level volumes.
- IDCentral: Focuses primarily on OCR and basic document processing. Limited geographic coverage compared to what most international banks need, and the integration options are fairly basic.
- IDWise: AI-driven approach with decent fraud detection capabilities. However, their global coverage is limited, and from what we’ve seen, the integration process can be complex for larger institutions.
Most banks need a solution that can handle diverse document types from multiple countries while maintaining consistent accuracy. That’s where we’ve focused our development – building something that works whether you’re verifying a UK council tax bill or a utility statement from Southeast Asia. The API-first approach also means your existing systems don’t need major changes to get up and running.

FAQs
Do employees need the same address verification as customers?
Yes, employee address verification follows similar standards to customer verification for compliance purposes. HR and compliance teams should coordinate on documentation requirements.
How often should address information be updated for existing customers?
Regular review cycles vary by institution and risk level. High-risk customers may need annual updates, while standard customers might be reviewed every 2-3 years.
Can automated systems verify all types of address documents?
Most automated systems handle standard utility bills and bank statements well. Complex documents like tenancy agreements or foreign documents may still require manual review.
What happens if a customer's proof of address is rejected?
Customers are typically asked to provide alternative documentation or clearer copies. Some institutions offer guidance on acceptable document types to avoid repeated rejections.
