Unexpected phone calls from unfamiliar numbers have become a daily nuisance—and sometimes, a serious threat. One such number raising eyebrows in the UK is 07700151855, which many claim is linked to HelloFresh promotional calls.
But with the rising tide of phone scams and spoofed numbers, it’s essential to ask: Is this HelloFresh calling, or could it be a scammer in disguise? This article dives deep into reported user experiences, official statements, and 2025 fraud trends to help you determine whether to trust or block this number.
Who is Calling 07700151855?
The number 07700151855 is a UK mobile number frequently linked to HelloFresh’s marketing team, often used to offer promotions or win back former customers. As of 2025, it has been searched over 327,000 times with more than 270 user reports, many labeling it as persistent or intrusive.
While some calls are confirmed to be legitimate, others raise concerns over aggressive sales tactics and unwanted contact. HelloFresh has acknowledged using third-party services for outreach, which include this number. Still, caution is advised—never share personal or financial details unless you’re sure of the caller’s identity. Always verify via HelloFresh’s official channels.
Who owns 07700151855?
The phone number 07700151855 is registered to Nationwide Telephone Assistance Ltd, a UK-based telecommunications company incorporated on November 1, 2001. Their registered office is located at Ivy Lodge Farm, 179 Shepherds Hill, Harold Wood, Romford, Essex, RM3 0NR. The company is actively involved in “Other telecommunications activities” as per the UK Standard Industrial Classification.
As of 2025, the number has been looked up over 327,000 times, with numerous user comments contributing to its overall negative rating. Reports include repeated calls even after opting out and calls at inconvenient times.
Risks of Answering Calls from 07700151855
Answering calls from 07700151855, a number associated with HelloFresh’s third-party marketing efforts, may seem harmless, especially if you’re a former customer. However, in 2025, with increased scrutiny on data misuse and deceptive sales practices, there are multiple risks you should be aware of. Here’s a full breakdown with the latest stats, reports, and trends.
1. Third-Party Data Misuse (ICO 2025 Penalty Report)
Although HelloFresh acknowledges using third-party sales agencies, many users have reported receiving calls after opting out, indicating poor consent management. According to the Information Commissioner’s Office (ICO) April 2025 report, over 9 companies were fined a combined £2.3 million for illegally contacting individuals without GDPR-compliant consent. If your details are being used without explicit permission, that’s a data protection violation.
2. Aggressive Sales Tactics and Subscription Traps
Numerous users on WhoCalled.co.uk and Reddit describe pressure to resubscribe using time-limited deals. The UK Competition & Markets Authority (CMA) in March 2025 flagged misleading subscription renewals as a top concern in digital marketing, especially when verbal consent alone is treated as a contractual agreement. Several HelloFresh complaints allege reactivation without written confirmation, which is legally questionable under consumer rights law.
3. Voice Phishing (Vishing) Attacks Rising
Calls from 07700151855 sometimes involve the caller requesting addresses or birthdates “for verification.” This is a red flag. The National Cyber Security Centre (NCSC) reported in its Q1 2025 bulletin that vishing now accounts for 34% of all initial access cyberattacks, up from 25% in 2023. Scammers can use this info to bypass identity checks at banks or delivery services.
4. Unauthorized Subscription Reactivation
A growing number of users claim they were re-billed or delivered HelloFresh boxes without full confirmation. A 2025 Which? Investigation found that 1 in 6 online subscription services in the UK restarted user accounts after vague or partial confirmations, usually gathered via outsourced sales teams. This violates FCA standards for clear, documented user consent.
5. Privacy Profiling for Behavioral Targeting
Even if you don’t share financial details, telling the caller why you canceled (“too expensive,” “don’t like meat options”) helps third-party firms create consumer profiles. According to Which? Privacy Report 2025, over 19% of UK consumers have had their behavior-based data resold, often without knowing. This can lead to more tailored (and more manipulative) sales calls later.
6. Number Tagging & SIM-Swap Risks
Answering calls marks your number as “active” in telemarketing systems. These numbers are sometimes resold to less secure networks. The UK Telecom Fraud Taskforce noted a 21% rise in SIM-swap frauds in 2025, many of which began with interaction via cold calls. A flagged “engaged” number becomes a bigger target for identity theft or number cloning.
7. Voicemail Traps & Callback Deception
Missed calls from this number often trigger voicemails urging a call back. Though 0770 numbers don’t charge premium fees, spoofing and rerouting are a rising concern. In a 2025 report by Ofcom, 1 in 11 users who returned a marketing call ended up connected to a redirected extension that collected additional data or opted them into services without consent.
8. Psychological Manipulation & Mental Fatigue
Persistent calls—even when ignored—can induce anxiety, annoyance, or decision fatigue, especially among older or vulnerable users. A Mind UK mental wellness study in 2025 highlighted that 45% of individuals aged 50+ felt “pressured into decisions” due to cold-call fatigue. This emotional stress can increase the risk of agreeing to unwanted services just to end the conversation.
9. Cross-Selling of Your Data to Other Brands
Several former HelloFresh users noted getting calls from unrelated lifestyle or subscription services within weeks of speaking to 07700151855. This suggests that your consumer data may be shared or sold. In early 2025, the ICO fined a well-known lead generation firm for cross-marketing users’ data without consent. Sharing your preferences with one service could open you up to a network of aggressive telemarketers.
10. Lack of Accountability for Third-Party Calls
If you agree to something over the phone and there’s a dispute, you may find it hard to get a resolution. Why? HelloFresh often deflects responsibility to its marketing partner. In 2025, the Consumer Advocacy Group UK documented over 3,400 unresolved complaints where customers were caught between brands and outsourced agents, often without proof of what was agreed upon.
How to Protect Yourself If You Receive a Call from 07700151855 (Unique Tips)
1. Ask the Caller to Confirm Your Last Interaction
Scammers often guess or use vague statements. Ask specifics like your last delivery date or canceled box. Legit agents from HelloFresh will know, scammers won’t. In a 2025 YouGov survey, 68% of consumers were able to identify fraud by asking a simple account-related question that the caller couldn’t answer.
2. Use the “Three-Second Rule” to Detect Auto-Dialers
Stay silent for 3 seconds—telemarketers using predictive dialers usually have a pause or click before speaking. According to Ofcom’s Telecom Regulation Report (Q1 2025), 74% of spam calls originate from auto-dialers that are triggered only when you answer.
3. Avoid Saying “Yes” or Confirming Your Name
Scammers may record your voice to exploit voiceprint-based verification systems used by banks and apps. In 2025, UK Finance reported a 31% rise in biometric fraud, with a significant number of breaches traced back to voice clips collected via unsolicited calls.
4. Keep a “Call Log” to Spot Patterns
Noting call times and dates helps you track harassment trends. The Telecom Fraud Intelligence Bureau (TFIB) found that 80% of flagged scam numbers reappear in call logs of repeat targets within 10 days. This is especially common after engaging with one call.
5. Insist on Email Confirmation Only
Say: “Please send me this offer via your official email.” Reputable agents will follow through; scammers rarely will. According to Consumer Action UK’s 2025 Digital Trust Index, 91.6% of legitimate companies complied with customer requests to switch from phone to verified email.
6. Verify Phone Offers on the HelloFresh Website
Most genuine HelloFresh offers are mirrored on their site or app. If the caller’s discount isn’t visible there, it’s likely part of a targeted reactivation push by third-party partners. Which? UK’s 2025 Subscription Watch revealed 17% of phone-only offers differed from the official site, raising transparency concerns.
7. Watch for “One Free Box” Subscription Traps
Multiple complaints show users were enrolled in full plans after accepting a “free box.” This marketing tactic skirts UK transparency guidelines. The CMA 2025 Subscription Report logged over 12,400 formal complaints in Q1 2025 regarding hidden renewals following promotional trials.
8. Activate Spam Blocking with Your Mobile Provider
Most UK networks now offer built-in spam filters. For example, Vodafone Secure Net blocked over 14.2 million spam calls in Q1 2025 alone. EE’s Call Protect and O2’s Extra Shield also saw record usage. Use these tools to filter calls from numbers like 07700151855 before they reach you.
9. Avoid Participating in Phone “Surveys”
Surveys disguised as feedback forms often collect personal data like income, household size, and lifestyle. This data fuels targeted telemarketing or is sold to third-party advertisers. In the 2025 UK Consumer Data Tracker, 24% of survey participants reported receiving unrelated marketing calls within 72 hours.
10. Delete Saved Payment Info from HelloFresh
If your account is inactive, go to your HelloFresh profile and remove any stored payment methods. This ensures that even if your account is reactivated by mistake (or over the phone), no charge can be processed. In 2025, the Financial Ombudsman Service reported 143 disputes where consumers were charged months after cancellation due to saved card data.
Common Complaints and Reported Behavior – 07700151855
The number 07700151855, known to be linked with HelloFresh’s outsourced marketing outreach, has triggered a wave of complaints across UK consumer forums in 2025. While some calls may be genuinely promotional, others reflect a pattern of nuisance behavior, questionable data practices, and weak consent protocols. Below is a detailed overview of the most reported behaviors, supported by current insights and statistics.
1. Persistent and Repetitive Calling
One of the most common complaints is the sheer frequency of calls from 07700151855. Users report receiving up to three to five calls a week, even after opting out or blocking the number.
According to data from WhoCalled.co.uk, this number has been looked up over 327,000 times and rated as “nuisance” or “untrustworthy” by more than 72% of users. Ofcom’s Q1 2025 Telecom Abuse Report also reveals that 44% of all marketing-related call complaints in the UK are tied to repeated or persistent calling, often by third-party firms operating on behalf of known brands.
2. Calls to Individuals Who Never Used HelloFresh
A surprising volume of complaints comes from individuals who have never used HelloFresh or interacted with their services. This suggests the number is not only used for customer retention but also for cold outreach using external lead lists.
The Information Commissioner’s Office (ICO) in early 2025 fined nine companies for using marketing data without verified opt-in consent, often acquired from loosely regulated affiliate campaigns. These practices highlight growing concerns about consumer data being misused under the guise of “partnered offers.”
3. Aggressive and Scripted Sales Approaches
Users frequently describe the callers as following a tight script, pushing phrases like “this is a limited-time offer” or “your account is still eligible for free boxes.” These tactics are meant to instill urgency and convert hesitant users into reactivating subscriptions.
A 2025 Which? A survey found that 61% of respondents who received phone-based subscription pitches felt pressured or misled during the call. Many of the scripts used by outsourced call agents fall just short of being deceptive but still rely on aggressive persuasion.
4. Unclear or Ambiguous Consent for Subscription Reactivation
Several users have shared experiences where their HelloFresh subscriptions were restarted without a clear agreement, often after engaging in what they believed to be an information-only call. In many cases, no written confirmation or follow-up email was sent.
According to the CMA’s 2025 Subscription Transparency Framework, over 19% of food-related subscription services in the UK were found to have ambiguous or undocumented consent triggers, especially when reactivations occurred after third-party calls.
5. Lack of Caller Transparency
Another major concern is that callers often fail to clearly identify themselves or the company they’re calling from. Some users say the caller simply says, “We’re calling on behalf of a food box service you’ve used before,” without ever mentioning HelloFresh directly.
This ambiguity breeds distrust. A 2025 audit by UK Consumer Voice showed that 28% of scam complaints involved unclear or vague caller identification, which violates PECR (Privacy and Electronic Communications Regulations) standards requiring businesses to be upfront about their identity and purpose.
6. Calls at Inconvenient or Intrusive Times
Many users report receiving calls outside standard business hours, including early mornings, late evenings, and weekends. While this may not breach regulations directly, it goes against industry best practices.
The Direct Marketing Association’s 2025 guidelines recommend contacting consumers between 9 AM and 6 PM on weekdays unless explicit consent has been given for other times. In a Which? poll, 38% of consumers said they are more likely to consider a call “spam” if it arrives outside normal business hours.
7. No Clear Option to Opt Out
One of the more troubling issues is that many of these calls do not offer a clear or easy way to opt out of future communication. Some users report being hung up on when they requested not to be called again, while others were vaguely told that “your preferences will be noted,” only to continue receiving calls.
This violates basic data rights under GDPR Article 21, which ensures every individual has the right to object to direct marketing. The ICO’s Enforcement Update (April 2025) confirms that £840,000 in fines were issued in Q1 to firms that failed to provide clear opt-out methods during sales calls.
8. Subscription Charges Following Unconfirmed Calls
Perhaps the most serious complaints come from individuals who noticed their HelloFresh subscriptions were reactivated or charged shortly after speaking with someone at 07700151855, even though they claim they never agreed to it.
In many of these instances, there was no written or digital confirmation—only the phone call. The Financial Ombudsman Service reported 143 complaints in Q1 2025 involving unauthorized subscription charges, particularly in industries where sales are outsourced and verbal agreements are poorly documented
UK Regions Most Affected by 07700151855
Recent analysis from Tellows UK, WhoCalled.co.uk, and Truecaller UK reveals that certain UK regions are experiencing significantly higher call volumes from 07700151855—a number linked with outsourced HelloFresh marketing campaigns. These calls often involve reactivation pitches, time-limited discount offers, and in some cases, repeated contact despite opt-out requests.
1. Greater London
Greater London tops the list with an estimated 7,200–7,500 reported calls as of Q2 2025, representing approximately 18% of national complaints. The high concentration of HelloFresh customers, online delivery usage, and dense urban population make this region especially vulnerable to frequent reactivation marketing.
Residents report daily calls, some describing them as “aggressive” or “misleading,” with pressure to restart subscriptions using “exclusive” phone-only discounts.
2. South East England (Including Kent, Surrey, Berkshire)
South East England follows closely, contributing approximately 5,000–5,300 call reports, or about 13% of the UK total. This region shows a notable trend of unsolicited calls to former HelloFresh users, often weeks or months after they canceled their plans.
3. West Midlands (Including Birmingham, Coventry, Wolverhampton)
Estimated to have around 4,200–4,400 complaints, the West Midlands accounts for nearly 11% of total national reports. Calls here are often described as persistent, sometimes arriving at non-standard hours (early morning or late evening).
4. Greater Manchester
Greater Manchester reports between 3,500–3,700 calls, approximately 9% of total activity tied to this number. Feedback from this region includes complaints about automated opening messages, pushy reactivation attempts, and confusing references to past subscriptions.
Some users noted that their subscriptions were reactivated without receiving written or email confirmation, which is a breach of subscription transparency best practices.
5. West Yorkshire (Leeds, Bradford, Huddersfield)
This region accounts for roughly 2,700–2,900 calls, or 7% of reported complaints. Several cases in West Yorkshire involve silent calls, where no agent speaks, or calls that disconnect immediately after answering—a behavior often associated with predictive dialers.
Consumer protection groups such as Age UK Leeds have raised concerns, as many complaints come from elderly or vulnerable residents who find the repeated calls distressing.
6. Scotland – Central Belt (Glasgow, Edinburgh, Stirling)
Scotland’s Central Belt, particularly Glasgow and Edinburgh, has recorded an estimated 2,400–2,600 complaints, comprising around 6.5% of total UK reports. The calls here often involve vague references like “your old HelloFresh account” or “you’re still eligible for a free box,” without offering a clear opt-out.
According to the Scottish Scam Advisory Panel’s 2025 update, this number was added to its list of “Nuisance Marketing Watch Numbers” due to repeated unsolicited activity.

Technical Insight: The Risk of Caller ID Spoofing in 2025
Caller ID spoofing is a growing threat in 2025, where scammers fake trusted numbers, like 07700151855, to make you believe a call is from a known company such as HelloFresh. Using weaknesses in phone networks and VoIP systems, fraudsters disguise their real number, increasing the chance you’ll answer and share personal information.
According to the NCSC, 43% of scam calls in Q1 2025 involved spoofed IDs, while UK Finance reported £58 million in losses linked to such calls. To stay safe, don’t trust caller ID alonealways verify through official channels and use spam-blocking tools from your provider or apps like Truecaller or Hiya.
Conclusion
While 07700151855 is officially associated with HelloFresh’s marketing efforts via third-party agencies, the number’s behavior, ranging from persistent calls and vague reactivation pitches to a lack of transparency and opt-out options, has led to widespread user frustration and concern.
