A standard UK First Class stamp currently costs £1.65 for a regular letter up to 100g, with a rise to £1.70 scheduled from 7 April 2025.

Current UK First Class price

  • Single First Class letter stamp (up to 100g): £1.65.
  • This price has applied since 7 October 2024 , when it was increased from £1.35.

Upcoming price increase

  • From 7 April 2025 , Royal Mail is set to raise the First Class stamp price to £1.70.
  • At the same time, Second Class will go from £0.85 to £0.87.

Quick context

  • The First Class price has climbed sharply over the last few years, more than doubling since the end of 2021, driven by falling letter volumes and higher delivery costs.
  • If you want to avoid the April 2025 rise, buying First Class stamps before that date lets you use them later at the old price (as long as they have the barcoded design). Always check Royal Mail’s site or your local post office for any last‑minute changes.
