When did your current contract with Three Business start?

Changes to your Monthly Charge are determined by when you joined, upgraded, or added a new line. If you have more than 1 contract with us, they may be eligible for different increases based on their individual start dates.

I joined, added a new line or upgraded on or after 12 January 2025

Our new pricing structure is tiered based on customers' original monthly charges, ensuring that the annual increases each April are clear and fair. If you joined, added a new line, or upgraded your plan (phone, SIM or broadband) on or after 12 January 2025, your Monthly Charge will increase each April by a fixed amount. 

The increase is based on your plan’s original Monthly Charge (before any promotional discounts). This will happen each April, during and outside your minimum term.

Your new Monthly Charge

Each April, we’ll calculate your new Monthly Charge by:

  1. Taking your current Monthly Charge as of March
  2. Adding a fixed increase based on your plan’s original Monthly Charge (before any promotional discounts)

All charges and increases exc. VAT.
