Changes to your Monthly Charge

From 1^st April 2026, we’re updating your annual price increase terms to a more transparent approach, which moves away from % based price rises and uses amounts shown in pounds and pence, so that you can see more clearly what the change to your monthly charge will be from April each year. ​ 

Your allowances and features remain the same, and you can continue to use your services exactly as you do today. 

 Your monthly charges will increase the 1^st April by a fixed amount based on your plan.  

You’ll see this annual price change on your bill from 1^st April 2026 and onwards. 

Find out what your new Monthly Charge will be using our table below 

The price increase in the table above only applies to your recurring Monthly Charge and does not apply to any device payments.

Our right to increase your Monthly Charge by a set amount each year is set out in section 4.1 (or section 3.1, if you are a business customer) of your terms and conditions (please select the relevant terms). Please note that we calculate the charge of your monthly increase to 2 decimal places and when calculating these charges, we will round up the price to the nearest penny. 

We’ll contact you either via SMS, email, or letter to remind you of the increase and when this will apply. 

The increase you will see will be dependent on when your current contract started – this may be when you joined Three or last upgraded your account.  

We know you may also have multiple contracts with us and these may be eligible for different increases dependent on their individual start dates.

The increase only applies to your recurring Monthly Charge and does not apply to any device finance payments, Add-ons, or out of bundle charges. 

Similar to many other mobile providers, our Pay Monthly plans are subject to an annual price change. The increases reflect inflationary pressures we are facing as a business including energy prices, supplier increases, and increased staffing costs. Despite this change, our prices remain some of the most competitive in the market and we have a range of support, including a social tariff via SMARTY, available for customers struggling with their finances. 

We understand that you may want to discuss or look at options for your contract with us due to the increase. We also have a range of support options for any customers who may need this. 

You can check your bills and account information by logging into My3 or downloading the Three App. You can also check our range of support options for customers, here.
