What is certain about future Royal Mail pricing?

How do Royal Mail pricing structures work?

Royal Mail segments mail primarily by physical format rather than content, with strict dimensional boundaries determining category. Letters must not exceed 240mm x 165mm x 5mm and 100g. Large Letters allow 353mm x 250mm x 25mm up to 750g. Parcels then divide into Small (450mm x 350mm x 160mm, 2kg max) and Medium (610mm x 460mm x 460mm, 20kg max).

Standard postage stamps include VAT within their face value, though no separate tax is added at purchase. Franking machines operate on licence agreements with Royal Mail, offering per-item discounts—typically 3p to 50p depending on format—against stamp equivalents. These Mailmark rates have remained stable since April 2025, widening the cost advantage for high-volume senders following the October stamp and parcel increases.

International pricing introduces additional variables including destination country groups, speed of service (Economy surface vs Airmail), and customs documentation requirements. Economy services typically require longer transit times but offer significant savings for non-urgent parcels, with October 2025 seeing particular volatility in these budget tiers.
