How does meter reading submission via WhatsApp work?

A utility sends a WhatsApp template with a reading reminder, the customer replies with the reading or a meter photo, and the billing system receives it by interface and checks plausibility. With SendSeven, utilities collect the reading in a Flow, save the photo link on the contact and hand special cases to the team.

WhatsApp for Utilities: meter readings, outages and service in the chat

Q: Can customers submit meter readings via WhatsApp?

Yes, if the utility uses the WhatsApp Business API. The customer sends the meter reading as a number or as a photo of the meter. In SendSeven, a Flow with the Collect Input block asks for meter number, reading and photo one after another and saves the link to the photo in a contact field. Your billing system checks plausibility and receives the values via REST API, Webhooks, Zapier, Make or n8n. How to set up the handover is shown in the webhook guide.

Q: What does a WhatsApp Channel offer utilities?

A WhatsApp Channel is a one-way distribution list: the utility posts news, followers read and react, but they cannot reply. That is enough for notices about roadworks, tariffs or maintenance windows. Meter readings, a move or follow-up questions about an outage need a dialogue with the individual customer, and that is what the WhatsApp Business API is for. Our comparison of broadcast, newsletter and group explains which path fits what.

Q: Is WhatsApp Business GDPR-compliant for utilities?

That depends on how you use it, not on the app alone. What matters is documented consent, a data processing agreement and no address book sync, which the Business App triggers on a company phone. Through the API with SendSeven, your data sits in Frankfurt, the AI runs in the EU and does not train on customer data. This is not legal advice. More in our article on WhatsApp Flows and GDPR.

Q: What does the WhatsApp Business API cost a utility?

Two items add up. Since 1 July 2025, Meta charges for every delivered template by category and recipient country. Since 1 October 2026, Meta also charges for service messages inside the 24-hour window, with 1,000 per number and month free of Meta fees. On top comes SendSeven from €49 per month, with the AI agent and Flows from Professional at €79, plus the SendSeven price per outgoing message. Details on the pricing page and in the article WhatsApp pricing 2026.

Q: How do utilities inform customers during a power outage?

Best with a message to everyone affected before the hotline starts ringing. You segment contacts by a contact field such as the postcode and send a WhatsApp template with the location of the fault and the expected fix. If the WhatsApp message is not delivered, a Flow automatically sends an SMS. The AI agent answers follow-up questions about status and duration from the knowledge base. More on how the channels work together in the article SMS for business.

Q: When does the meter reading have to be submitted?

Typical occasions are the annual reading, a move, a change of supplier and a price change. The deadline is set by the supplier in its request, often with a window of a few days, and the rules differ by country. Utilities can automate the reminder: the billing system starts a Flow via the REST API, Zapier, Make or n8n, which sends a WhatsApp template at the right time and asks for the reading directly in the chat.

Q: May the supplier estimate the meter reading?

Yes, under conditions, and the rules differ by country. In Germany, § 40a EnWG allows a bill to be based on an estimate if the customer has not submitted a reading despite being obliged to, or if the supplier cannot determine consumption for reasons it is not responsible for. The basis is mainly consumption in the previous billing period, and the estimate must be clearly marked on the bill. This is not legal advice. The easier the submission via WhatsApp, the less often a utility has to estimate.

Q: How do customers report a move via WhatsApp?

The customer writes to the utility in the chat, and a Flow then asks for the old and new address, the move date and both meter readings, with a photo if wanted. The answers land in contact fields and go to your billing system via REST API, Webhooks, Zapier, Make or n8n. Your team only checks special cases in the inbox, and the AI agent answers questions on the side. The data handover is described in the webhook guide.

Between two annual bills your customer hears nothing from you for ages, but hears from comparison portals every day.

7.1 million electricity customers in Germany switched supplier in 2024, a record.¹ Not because of 2 cents per kWh, but because meter readings by phone queue, unanswered tariff enquiries and unreadable bills destroy trust.

SendSeven makes utilities and energy suppliers reachable where your customers already are: WhatsApp, email, SMS, live chat and more.

The bill

What outdated customer communication is actually costing you

Most energy suppliers underestimate how much margin they lose through phone queues, undelivered emails and missing digital channels. Here are the figures for a typical utility with 80,000 contract customers:

Call volume for routine enquiries

€0/month

Meter readings, direct debit changes, change-of-address notifications, tariff enquiries: these four enquiry types account for over 60% of total call centre volume. Each call costs €8.50 in staff time.

Calculation example: 80,000 customers × 5% call monthly with routine questions = 4,000 routine calls × €8.50 per call = €34,000 for questions that an AI agent can answer.

Customer churn from poor accessibility

€0/month

Winning a new customer costs suppliers €150–250 on average. When customers leave because enquiries go unanswered or communication feels outdated, you lose not just margin. You pay for your competitors' acquisition.

Calculation example: 80,000 customers × 14% switching rate¹ = 11,200 switchers/year. 38% are dissatisfied with the service.² A conservative estimate is that 25% of them switch because of service = 2,800 avoidable switchers × €180 lost annual margin = €42,000 avoidable margin loss/year.

Campaigns nobody reads

€0/month

Green electricity upselling, solar offers, heat pump tariffs: your cross-sell campaigns by email reach an open rate of 18%. Of those who open, 2% click. The result: 99.6% of your customers never click the offer.

Calculation example: Via WhatsApp (over 90% open rate) instead of email (18%), at the same click and conversion rate, you get about 5× more tariff switches. Difference: €8,533 missed upsell revenue/year.

€0/year

Typical annual loss for a utility with 80,000 customers through phone-heavy processes, avoidable churn and unread campaigns.

Three perspectives, one problem

Why your utility is operating below its potential

Whether customer communications, sales or digitalisation, the symptoms differ, but the cause is the same: customer communication is fragmented and analogue, in a world that went digital long ago.

Customer Communications

Head of Customer Communications

Phone queues at meter reading time

During the 4 weeks of meter reading collection, call volume jumps by 300%. Customers wait over 12 minutes and leave 1-star reviews on Google.

Postal communication eats budget

Every bill, every tariff notice, every move confirmation by letter costs €1.80–3.50 including print and postage. With 80,000 customers, that quickly adds up to six-figure sums.

38% of your customers are dissatisfied with the service

More than a third of energy customers criticise the service quality.² At the same time, 83% of 16 to 74-year-olds in Germany use messengers.⁴ Your customers want to report an outage via WhatsApp, but the only channel is a contact form with a 48-hour response time.

Sales

Head of Sales

Cross-sell campaigns fizzle out

Green electricity upgrades, solar installations, wallbox tariffs: the email open rate is 18%. 82% of your customers never hear about your offer.

80% of switches happen online

In Germany, 4 in 5 switches of electricity and gas contracts happen online.³ 70% of new customers now come through external channels such as comparison portals.⁵ Your advantage as a local supplier is proximity and service. It becomes invisible when the only touchpoint is the annual bill.

No data on customer needs

Without digital communication channels you do not know which customers are interested in electric mobility, who is planning a heat pump or who is about to switch.

Digitalisation

Head of Digitalisation

Digital service? Missing at 89% of utilities

Only 11% of utilities actively use automated assistants in customer service. The rest handle routine enquiries manually, by phone and email, often with days of response time.

Siloed solutions without integration

An email tool here, telephony there, social media with marketing, a chat widget from a third party: no system knows the customer as a whole. Every channel is its own world.

Long project timelines for SAP integration

Every new tool means 6–12 months of SAP integration. By the time the WhatsApp channel is live, a competitor has already served 10,000 customers through it.

The solution

SendSeven: All channels. One inbox. Immediate impact.

SendSeven combines WhatsApp, email, SMS, live chat, Instagram DM, Messenger and Telegram in one inbox, and browser push complements your campaigns. Your service agents see every customer with the full contact history, whichever channel the enquiry comes through.

The built-in AI agent answers routine questions about meter readings, instalments and tariffs around the clock and hands over to your team when it cannot help or the customer asks for a person. Via WhatsApp broadcast, your campaigns reach an open rate of over 90% instead of 18% by email.

Use cases

Concrete scenarios for energy suppliers & utilities

Every use case shows the problem, the solution with SendSeven and the measurable result.

Problem

Meter readings overload the call centre

Every year at reading time: 4 weeks of emergency mode. 3,200 extra calls, waits of over 12 minutes, frustrated customers and exhausted staff. If no reading arrives, a supplier in Germany may estimate under § 40a EnWG.⁷ The estimated bill triggers the next call.

Solution with SendSeven

WhatsApp reminder + Flow for meter reading collection

Send a reminder to all customers in the reading area via WhatsApp broadcast. A Flow asks for meter number and reading, with a photo of the meter if wanted, and confirms receipt. Your billing system receives the values via REST API or webhook and checks plausibility. The AI agent answers questions, and unclear cases go to the service team in the central inbox.

Problem

Green electricity campaigns by email get ignored

You offer a green electricity tariff that costs only €4 more per month. But your email campaign reaches 18% opens and 0.4% conversion. 82% of your customers never open the email.

Solution with SendSeven

WhatsApp broadcast with a personalised tariff recommendation

Segment customers on the default supply tariff via tags and custom contact fields. Send a WhatsApp campaign with their personal savings potential. Interested customers reply directly in the chat, and your sales team advises live in the central inbox. More on this: raise open rates with WhatsApp.

Result

5× more conversions

More tariff switches

Instead of 320 tariff switches/year by email, now 1,600 via WhatsApp = €76,800 extra revenue/year

Problem

Move notifications tie up service capacity

Every move notification takes 15–20 minutes to process: old meter reading, new meter reading, change of address, tariff check. At 400 moves/month, that is 130 working hours.

Solution with SendSeven

Structured data capture via Flow

A Flow guides customers step by step through the move notification: old address, new address, meter readings, move date. Via REST API, Webhooks, Zapier, Make or n8n, the data goes to your billing system. Your team only checks special cases in the central inbox, and the AI agent answers questions on the side.
