What Are 0345 Nuisance Calls and Why Are They a Problem in the UK?
0345 numbers are non-geographic numbers used across the UK by businesses, charities, and public services. They cost the same as local landline numbers, making them a popular choice for customer support and service lines.
The problem? Increasing numbers of nuisance calls originate from 0345 numbers. This includes persistent silent calls, spam marketing, scam attempts, and even harassing behaviour. While legitimate businesses use 0345 numbers for real customer communication, nuisance callers exploit them because recipients are more likely to pick up.
A freelancer, Olivia, found her workflow continually disrupted by daily calls from 0345 numbers she didn’t recognise. Some were silent or hung up instantly, while others delivered pushy sales pitches for services she’d never requested. Over time, the constant interruptions led to lost work hours and stress.
What Legal Protections Cover You Against 0345 Nuisance Calls?
Legal protections for nuisance calls are robust in England and Wales. You’re primarily safeguarded by the Privacy and Electronic Communications Regulations 2003 (PECR) and the Communications Act 2003. These rules cover individuals, sole traders, and some small businesses.
- PECR: Prohibits unsolicited marketing calls to individuals and sole traders who register with the TPS. If your number is on the TPS, organisations need your explicit consent to call you and must stop if you opt out directly.
- Communications Act 2003: Makes it unlawful to use telephone networks to cause annoyance, inconvenience, or anxiety via persistent or offensive calls. Any harassing, threatening, or intimidating calls are strictly forbidden.
If a company keeps calling after you’ve expressly asked them to stop, you can use PECR to demand in writing that all marketing contact ceases immediately. Failure to comply can result in enforcement by the ICO.
0345 Nuisance Calls vs Legitimate, Robocall, and Scam Calls: Spot the Signs
To take the right action, it’s vital to distinguish a legitimate call from unwanted, scam, and automated (robocall) attempts.
Red flags for a nuisance or scam 0345 call:
- You don’t recognise the caller or didn’t request contact.
- The call is silent or cuts off quickly—often a result of automatic diallers.
- You’re pressured to act urgently, such as “your account will be blocked.”
- There’s a request for sensitive data like payment details or PINs.
- You hear a pre-recorded message (common in robocalls).
- The caller uses a generic or spoofed business name.
An IT contractor, Daniel, received an 0345 call claiming to be from his bank’s fraud prevention team. When asked for his security details “to unblock his account,” Daniel realised it was a scam and refused. The caller then became aggressive, confirming its fraudulent nature.
How to Block 0345 Nuisance Calls on BT, EE, O2, Vodafone, iPhone & Android
Protecting yourself from nuisance calls starts with learning how to block them on your network and device. Below is a comparison of the main blocking methods by provider and device:
| Provider/Device | How to Block 0345 Calls | Steps to Activate | Extra Tips |
|---|---|---|---|
| BT landline | Call Protect or 1572 | Activate through MyBT or dial 1572, follow prompts | Add 0345 numbers to your specific blacklist |
| EE mobile | Built-in call blocking, My EE app | Open recent calls, tap ‘Block’, or use app | Device-level blocking helps, even if numbers keep changing |
| O2 mobile | O2 Call Protect, device settings | Use O2 app or block numbers directly on device | Use both O2 Call Protect and device options for full cover |
| Vodafone | Secure Net & device blocking | Activate Secure Net or set up via call settings | Secure Net helps filter scam numbers automatically |
| iPhone | Block via Phone app | Go to Recent Calls, click ‘i’, select ‘Block Caller’ | Keep your iOS updated for the latest spam filtering features |
| Android | Phone app or third-party apps | Tap number in call log, select ‘Block/Report Spam’ | Apps like Truecaller add further protection |
- For callers who repeatedly bypass blocks, contact your provider for advanced nuisance call blocking services.
Always keep a log of the dates, times, and content of nuisance calls—even after you block numbers. Callers may switch numbers or use caller ID spoofing. Proper records make your future complaints stronger and more effective.

What Evidence Should You Collect Before Reporting 0345 Nuisance Calls?
Strong evidence is the backbone of any successful nuisance call complaint. Document every instance of a nuisance call—this enables regulatory bodies to take swift and effective action.
Your evidence log should include:
- The 0345 number displayed on your phone
- The date and time of each call
- The content or purpose of the call (actual script or written summary)
- Any voicemail or audio recording (if it’s legal and you’re a participant in the call)
- Screenshots of call logs, call history, or related text messages
Logging Dates, Times, and Content: What Counts as Concrete Proof?
- Use a paper or electronic log to note every nuisance call, including number, date, and time.
- If you’re a participant, you’re legally permitted to record calls in England and Wales. Stating that you’re recording the call creates an extra layer of legal assurance.
- Collect and store screenshots or transcripts, especially if you spot a repeating pattern.
An ecommerce microbusiness used our downloadable call log to record details of a week’s worth of 0345 nuisance calls. This documentation was used in their ICO complaint and significantly strengthened their case.
How to Report 0345 Nuisance Calls to the ICO, Ofcom, or Police
If blocking hasn’t stopped the nuisance calls, it’s time to escalate.
Where to report:
- Unsolicited marketing or data misuse: Information Commissioner’s Office (ICO)
- Repeated, silent, or aggressive calls: Ofcom
- Threatening or abusive calls: Police (via 101 for non-urgent cases, 999 in emergencies), plus the ICO or Ofcom
How to report nuisance calls:
- Complete a complaint template with your evidence log.
- Go to the ICO’s website to submit marketing or data breach complaints. Use our tool to prepare a pre-filled ICO letter.
- Use Ofcom’s online portal to report silent or abusive calls, and attach your evidence.
- If the calls are threatening, report to police, and then inform the appropriate regulator.
When Should You Escalate to Authorities?
Escalation is warranted if:
- The calls are harassing or aggressive, or you receive several in a short timeframe.
- Threats or blackmail are made against you or your business.
- You or colleagues feel at risk.
Our complaint letter generator ensures that every report contains the key legal requirements and supporting documents, maximising the chance of quick enforcement action.
Registering with the Telephone Preference Service (TPS): How Effective Is It?
The TPS offers a free, nationally recognised opt-out from unsolicited marketing calls. Once registered, it’s illegal for most UK companies to cold-call your number without your consent.
However, some nuisance callers—including scammers, certain overseas firms, and those using spoofed numbers—may ignore the rules. Service notifications and non-marketing calls are permitted even after TPS registration.
What to Do if TPS Registration Doesn’t Stop Persistent 0345 Calls
If nuisance calls continue after you’ve registered:
- Use your device or provider’s call blocking tools.
- Keep detailed evidence logs (dates, numbers, call details).
- Report each ongoing incident to the ICO or Ofcom.
A travel agency found that TPS registration greatly reduced legitimate marketing calls, but “survey” and silent robocalls on 0345 numbers persisted. By logging incidents and sending a formal report via our tool, official action was taken and nuisance calls dropped sharply.
Key Legal Rights for Small Businesses vs Individuals: Who’s Protected?
Understanding which legal protections apply can make reporting much more effective. Here’s how the rules break down:
| Recipient Type | PECR Protection for Nuisance Calls | TPS Registration Allowed |
|---|---|---|
| Individual | Yes | Yes |
| Sole Trader | Yes | Yes |
| Limited Company | No (marketing rules less strict) | No |
- Individuals/Sole Traders: Protected from unwanted marketing if they register with TPS and can block and report nuisance calls easily under PECR and Communications Act.
- Limited Companies: Not fully covered by PECR marketing rules, but protected from harassment and threats under the Communications Act 2003.
Even larger or incorporated businesses can take action against harassing or threatening behaviour from persistent callers under the Communications Act’s provisions.
Common Mistakes to Avoid When Handling 0345 Nuisance Calls
| Mistake | Why It’s a Problem | How to Avoid It |
|---|---|---|
| Not Recording Details | Weak evidence undermines complaints | Maintain thorough, dated evidence logs |
| Reporting to the Wrong Authority | Delays resolution or prevents redress | Choose ICO for marketing/data, Ofcom for persistent calls |
| Assuming TPS Alone Stops Calls | Some calls still get through | Combine TPS with blocking and reporting steps |
A creative consultancy tried to rely solely on phone blocking; as a result, key patterns went unlogged and their case stalled. Using our evidence template, they re-logged incidents, reported correctly, and saw action taken within weeks.

Frequently Asked Questions
Are 0345 numbers free to call or receive in the UK?
No. 0345 numbers are charged at your standard local (01/02) rate. For most mobile or landline users, calls are deducted from inclusive minutes, so you won’t usually incur extra charges.
How do I block 0345 nuisance calls on my mobile or landline?
Use your device’s built-in call blocking features—find the offending number in your call history, select ‘Block’, and confirm. For landlines, activate call blocking through your network provider (such as BT’s 1572 or equivalent services).
What sets a nuisance call apart from a scam or a legitimate 0345 business call?
- Legitimate call: Expected, from a known provider, relevant to your business or transaction.
- Nuisance call: Repeated, pushy or silent, not requested by you, possibly irrelevant.
- Scam call: Seeks to defraud you, requesting payment, access codes, or personal data.
Will registering with TPS completely eliminate unwanted 0345 calls?
No. TPS is a strong first step, but doesn’t block calls from overseas, scammers, or those ignoring the law. Use enhanced blocking and reporting for full protection.
How do I report a 0345 number to ICO or Ofcom?
Compile a detailed evidence log, complete the regulator’s online form, and attach your documents. Or, use our AI-generated complaint builder for a one-click report solution.
What happens after I submit a complaint—will I get compensation or follow-up?
The ICO or Ofcom may contact you for further information. Compensation is rare, but regulators can levy heavy penalties, and your complaint increases the pressure on offenders.
Can a business report nuisance calls to its main phone line?
Yes. Sole traders and partnerships have similar rights as individuals under PECR. Limited companies can act under the Communications Act if the behaviour crosses into harassment.
What extra legal rights do small businesses hold over individuals?
Sole traders benefit from PECR as well as general anti-harassment laws, while limited companies rely on broader harassment and communications regulations.
What immediate steps should I take if a 0345 call is harassing, abusive, or threatening?
Immediately block the number, log the call details, report urgent threats to the police, and file a formal complaint with the ICO or Ofcom using our guided templates.
What if TPS and blocking features don’t stop persistent 0345 callers?
Log all further incidents, escalate to the ICO or Ofcom, and use advanced blocking methods. Our expert-powered platform guides you through escalation to legal enforcement if required.
