1. Meter Reading Submission QR
A QR on the energy bill or meter label links to the meter reading submission form pre-filled with the account number. Customers photograph the meter or enter the reading on their phone. Eliminates estimated billing and reduces call centre volume.
2. Smart Meter Installation QR
A QR in the smart meter installation appointment letter links to: what to expect on the day, how to prepare (clear access to the meter), and what data the smart meter collects. Reduces installation refusals caused by misinformation.
3. Tariff Switch QR
A QR in the tariff renewal notice links to the tariff comparison page pre-loaded with the customer's usage data. One-tap tariff switching from the page. Transparency and ease of switching build trust and reduce churn to competitors.
4. Power Cut and Fault Reporting QR
A QR on the bill and welcome pack links to the local network fault reporting page and the national Power Cut helpline (105 in the UK). During a power cut, customers with battery power can quickly find local outage maps and estimated restoration times.
5. Energy Saving Tips QR
A QR on the bill links to a personalised energy saving tips page based on the customer's usage profile and home type. Utilities that help customers reduce bills build stronger long-term loyalty than those that maximise billing.
Putting this into practice
Start with the smallest real test you can run. Generate the code, print it at the exact size you plan to use, and scan it with two different phones in the lighting where it will live. Check that the destination page loads quickly on a mobile connection and that the call to action next to the code tells people what they will get. If anything feels slow or unclear, fix it before you print a full batch, because reprints cost more than a short test. Keep a note of the size, material, and placement that worked so the next batch starts from a proven setup.
Common mistakes to avoid
The most common mistakes are easy to avoid once you know them. Long payloads make modules tiny, low contrast makes edges hard to read, and text placed too close to the border eats the quiet zone the scanner needs. Covering a corner finder pattern with a logo or a sticker breaks detection entirely, and a code placed behind glare or on a curved surface fails even when the print is perfect. Review each of these points on a proof copy, and treat any failure as a reason to adjust the design rather than a reason to blame the scanner.
Quick checklist
- Keep the payload as short as practical so modules stay large.
- Keep dark modules on a light background with strong contrast.
- Leave a clear quiet zone on all four sides of the symbol.
- Test the printed code at the real viewing distance and lighting.
- Confirm the destination page loads fast on a phone.
- Recheck the code after any change to the link, design, or placement.
