Royal Mail surcharges can quickly add up, hitting your business with unexpected costs and delivery delays. Whether you’re sending a few letters a week or hundreds of parcels daily, knowing how to avoid these charges is essential. Even with a franking machine at hand, businesses are still being hit with surcharges due to simple mistakes which are avoidable.
In this guide, we’ll break down what causes surcharges and how to prevent them with simple, practical changes.
What Are Royal Mail Surcharges?
Surcharges are additional fees added when mail items don’t meet Royal Mail’s guidelines. They typically arise due to incorrect sizing, insufficient postage, or packaging issues.
Common surcharge reasons include:
- Incorrect size or weight.
- Poorly affixed labels.
- Non-Machineable items sent as standard.
- Incorrect format (e.g. Large Letter vs Small Parcel).
- Unreadable barcodes or franks.
Top Reasons for Surcharges (and How to Avoid Them)
1. Incorrect Sizing or Format
Solution:
2. Overfilled or Bulky Envelopes
Stuffing envelopes too full can push them into a different size category, even if the weight is low.
Solutions:
1. Use your franking machines integrated weighing scale to accurately weigh every item you frank. This will help ensure you are franking the correct amount for the item or items you are sending. Don’t have a franking machine? Get a franking machine quote today and avoid the surcharges today!
2. Choose the right envelope for your contents and avoid overstuffing. Use packaging that maintains the correct thickness and fits the format you’re franking for. View our range of business envelopes here.
3. Unreadable or Misaligned Franks
If the frank or Mailmark impression is smudged, too faint, or placed in the wrong position, it may not scan correctly, leading to a surcharge.
Solution:
Keep your franking machine well-maintained and regularly clean the printhead. Make sure you’re using approved franking ink and high quality franking labels to ensure legibility.
4. Incorrect Weight or Postage Selection
Solution:
Use your franking machines integrated weighing scales before applying your franking impression. Double-check that you’ve selected the right class and format for the item or items you are sending on your franking machine.
