Yes, 1157629839 is a legitimate telephone number used by E.ON Next for outbound calls regarding smart meter installations. Although your phone may flag it as potential spam due to high-volume automated dialing, it is an official business line.
You can safely verify this by logging into your E.ON Next online account or calling their verified contact number.
Is 1157629839 Safe?
1157629839 is safe and is officially recognized as an outbound communication channel for E.ON Next. The spam flag you see is a common false positive triggered by the high-frequency dialing systems used for national smart meter rollouts, rather than an indication of malicious intent.
Business Call Flagging
High-frequency call flagging occurs because modern mobile network filters mistake large-scale, automated service calls for nuisance traffic.
When utility providers manage thousands of appointments, the resulting call volume often causes network-level warnings, creating a false positive that mislabels legitimate business communication as spam.
| Caller Type | Source/Association | Typical Intent |
| 1157629839 | E.ON Next (Smart Meter Team) | Booking/Appointment reminders |
| 0800/0808 | Official UK Toll-Free | Customer service or general inquiries |
| 0333/0345 | National Business Rate | Corporate or service-based communication |
Legitimate service calls from large utility providers like E.ON Next are frequently misidentified as spam by mobile network filters due to the high volume of automated dialling.
A flagged number does not automatically mean a call is fraudulent; it reflects the call pattern, not the caller’s intent.
Whom does 1157629839 belong to?
This number is officially registered to E.ON Next. It is primarily utilized by their smart meter booking and installation teams.
While the number is legitimate, E.ON Next often employs third-party agencies or outsourced departments to handle the high volume of outbound calls required for their nationwide smart meter rollout.
Consequently, you may occasionally speak with representatives from these partner agencies rather than E.ON Next’s direct internal staff.
Why do I get calls from 1157629839?
You are likely receiving calls from this number for official account management related to your energy supply, primarily for scheduling installations, providing appointment reminders, or conducting customer outreach regarding energy efficiency upgrades.
- Scheduling Installations: E.ON Next proactively contacts customers to arrange the installation of smart meters.
- Appointment Reminders: They may be calling to confirm or provide reminders for a previously booked appointment.
- Outreach Efforts: If you are an existing customer, they may call to discuss upgrading your current meter or to explain the benefits of smart metering.
- Database Triggers: If you have recently moved or changed your energy status, your contact information may have been moved into an active outreach list for meter services.
How to verify 1157629839 is safe?
Because scammers can spoof (imitate) official numbers, it is wise to follow these verification steps even when a number is known to be legitimate:
- Use the Hang Up and Call Back Method: If you are suspicious, do not provide any personal information during the call. Hang up immediately, find the official E.ON Next contact number on your latest paper bill, or visit their official website. Call that number directly to verify if they have an active request to speak with you.
- Check Your Online Portal: Log in to your E.ON Next online account. Often, important notifications or requests for meter appointments will be reflected in your dashboard or messages center.
- Verify the Purpose: If a caller asks for sensitive information (like your bank details or a one-time passcode sent to your phone), terminate the call. A legitimate representative from E.ON Next will generally have access to your account details already and should not need to ask for sensitive security credentials.
- Community Intelligence: Use reputable community resources like the E.ON Next Community forums to see if other customers are receiving similar calls or if there are current alerts regarding active scams targeting their customer base.
How to Identify and Verify Unknown Callers in the UK
Protecting your personal data requires a systematic protocol: never share security credentials, cross-reference the number via official search engines, and always utilize the hang up and call back method using a verified source.
Is 0115 a landline?
Yes, 0115 is the geographic dialling code for the Nottingham area. However, thanks to the rise of VoIP (Voice over Internet Protocol), businesses can now use 0115 numbers even if their operations are based elsewhere in the UK.
Never assume a caller is physically located in Nottingham simply because they use a local area code.
How to check who a phone number belongs to in the UK?
You can identify a caller by searching the number in search engines or dedicated databases like Who Called Me, checking official company contact pages, and being vigilant against spoofing (where scammers mask their identity using local area codes).
- Search the number: Enter the number directly into a search engine. Often, community forums like the E.ON Next Community or Who Called Me databases will display recent reports.
- Use official channels: If a caller claims to represent a specific organisation, hang up and call the company back using the number listed on their official website or the back of your latest bill.
- Check for spoofing: Be aware that scammers can clone (spoof) local numbers to build false trust. If a caller asks for sensitive information, like a one-time security code, it is almost certainly a scam.
