Identity theft costs UK businesses and individuals millions every year. Yet many offices are sitting on piles of sensitive documents—old invoices, payslips, bank statements, CVs—just waiting to be discovered by the wrong person. The solution? Knowing what to shred and when.
Here’s a practical guide to the 8 documents you should destroy immediately, plus why secure shredding matters for your business.
1. Payslips
Payslips contain a goldmine of personal information: names, addresses, National Insurance numbers, and bank details. Once you’ve recorded the information you need for tax purposes or pension contributions, shred them.
Why it matters: A fraudster with your NI number and bank details can open accounts in your name or commit tax fraud.
Retention tip: Keep payslips for 6 years for tax purposes, then shred securely.
2. Receipts
Receipts often contain credit card numbers, signatures, and sometimes even CVV codes. Even partial card information can be used for fraud.
Why it matters: Card details on receipts are a direct path to identity theft.
Retention tip: Shred receipts as soon as they’re no longer needed for accounting purposes.
3. Anything with a Signature
Documents bearing signatures—contracts, cheques, agreements—can be used to forge your signature on other documents or commit fraud.
Why it matters: Your signature is a key identifier that fraudsters can replicate.
Retention tip: Keep signed contracts for the duration of the agreement plus 6 years, then shred.
4. Bank and Credit Card Statements
Old bank and credit card statements reveal your financial history, account numbers, and transaction patterns—everything a fraudster needs to impersonate you.
Why it matters: Financial statements are a complete roadmap to your accounts.
Retention tip: Switch to paperless statements where possible. If you keep paper copies, shred after 6 years or once the information is recorded.
5. CVs and Job Applications
CVs and job applications are packed with personal identifiers: full names, addresses, phone numbers, email addresses, employment history, and sometimes even references. A single CV contains enough information for identity theft.
Why it matters: CVs are designed to showcase your personal details—making them a perfect target for fraudsters.
Retention tip: Shred CVs and applications immediately after hiring decisions are made, or after 6 months if you don’t hire.
6. Invoices
Business invoices contain customer details, account information, pricing, and sometimes payment methods. A data breach involving invoices can damage client relationships and expose your business to liability.
Why it matters: Invoices are a GDPR compliance issue—customer data must be protected.
Retention tip: Keep invoices for 6 years for tax purposes, then shred securely.
7. Expired Passports and Photo ID
Expired passports and photo ID documents can be used as templates for identity fraud or document forgery. Even though they’re expired, they’re still valuable to criminals.
Why it matters: Photo ID is the gold standard for identity verification—criminals can use it to open accounts or access services.
Retention tip: Shred expired ID immediately. Don’t leave it in a drawer.
8. Old Tax Returns and Financial Records
Tax returns and financial records contain your full financial picture: income, deductions, business details, and sometimes bank account information. After the required retention period, they become a liability.
Why it matters: Tax records are a complete financial profile that fraudsters can exploit.
Retention tip: UK law requires you to keep tax records for 6 years from the end of the financial year. After that, shred them promptly.
Why Secure Shredding Matters
Simply throwing sensitive documents in the bin isn’t enough. Dumpster diving is a real threat—fraudsters regularly sort through waste looking for discarded documents. Secure shredding ensures your documents are destroyed beyond recovery.
Benefits of professional shredding:
- GDPR Compliance – Demonstrates you’re taking data protection seriously
- Peace of Mind – Know your sensitive data is destroyed, not just discarded
- Chain of Custody – Receive a Certificate of Destruction proving documents were shredded
- Environmental Responsibility – Shredded paper is recycled, not sent to landfill
- Cost-Effective – Regular shredding prevents the need for expensive emergency clear-outs
How Often Should You Shred?
The answer depends on your business, but here’s a practical approach:
- Regular businesses – Weekly or fortnightly scheduled shredding keeps sensitive documents from piling up
- One-time clear-outs – If you’re clearing old archives or office relocations, on-demand shredding handles large volumes quickly
- Walk-in shredding – For smaller amounts, many businesses use walk-in services for flexibility
