What does a First Class stamp cost?

Right now in the UK:

• Standard First Class letter (up to 100g): £1.70.

• Large Letter First Class (up to 100g): £3.15.

From 7 April 2026 :

• Standard First Class will increase to £1.80.

Royal Mail says the rise is driven by falling letter volumes and higher delivery costs, and it’s the latest in a series of hikes over the last few years.

If you’re in another country (for example, the US), First‑Class rates are set separately by that country’s postal service, so the prices above apply to the UK only.
