All Charges exclude VAT.  From Customer’s bill date each April, the Monthly Charge will increase by a fixed amount depending on the plan’s original Monthly Charge. Plans with an original Monthly Charge of £9.99 or less will increase by £0.50 per month. Plans from £10 to £20 will increase by £0.75 per month. Plans from £20.01 will increase by £1.50 per month. All Business Broadband Plans will increase by £1.60 per month. All increases exclude VAT. Excludes Three Business Adapt. See Adapt Plan information for annual price increases. Visit the price increase page for full details. 

Three’s systems work to very small fractions, and each charge is rounded up or down to make it easier to read. This means that there may be a small inconsistency to the price shown in the shopping basket, compared to the statement which shows the price rise that will apply during the Minimum Term of the Plan and Customer’s bill, which both show the actual amount Customer will be charged. For more information, please see Three’s help and support pages or the Price Guide. The Plan’s Monthly Charge includes a £5 discount for paying by a recurring method, such as Direct Debit. The £5 monthly recurring payment discount and the annual price increase do not apply to Add-ons or Outside-of-Allowance Services. See Terms & Conditions | Three.
