Consumer Price Index

Everything you need to know about the CPI increase

What is the Consumer Price Index?

The Consumer Price Index measures the overall change in consumer prices over time based on a representative basket of household goods and services. The CPI rate is published by the Office of National Statistics.

How does CPI +3.9% affect my iD Mobile plan?

Your monthly plan will be adjusted each April by the CPI rate published in February (+3.9% fixed rate). Price adjustments do not affect add-ons or additional charges.

For 2024, the CPI rate (+3.9% fixed rate) is 7.9%.

Does the 2024 CPI +3.9% adjustment apply to me?

The April 2024 CPI +3.9% adjustment will apply if you've upgraded to or purchased a new iD Mobile 24-month phone plan on or after 1st November 2022 and before 1st February 2024.

If you are affected by the 2024 price adjustments, you'll receive a text from us in March 2024 confirming the exact adjustment that will be applied to your April 2024 bill onwards.

Why is iD adjusting prices?

Every year, most networks adjust their prices for customers as inflation rises. Historically, iD Mobile has implemented the lowest average price adjustments compared to the major networks (EE, Three, O2 and Vodafone).

We appreciate that price adjustments are of concern to consumers and are never welcome. However, inflationary pressure is hitting us all – both as consumers and as businesses, and the cost to operate and sustain our value-focused and highly reliable network is increasing.

Even with annual price adjustments, we always work to deliver value-focused offerings that will help us remain one of the most competitive in the market. Our aim is to continue delivering great service and features to our customers, such as data rollover, UK’s fastest 5G at no extra cost and free Roaming destinations. 

Why has iD moved from RPI to CPI since November 2022?

We believe that the Consumer Price Index (CPI) rate is better reflective of the true rate of inflation that goods and services are rising or falling. An additional +3.9% will be also applied to the CPI rate so we can maintain and improve our network and services.

Why has iD added +3.9% in addition to CPI?

The cost to operate and sustain a value-focused and highly reliable network is increasing. From our cost of supply with manufacturers, maintaining and developing the network infrastructure, and even the small but critical things – like delivering items to customers. The additional 3.9% will allow us to continue to invest in and improve our network and services.

What happens if CPI is negative?

In the unlikely event that CPI is negative, we would not factor the negative value in our calculations, and your plan will simply increase by 3.9%.

I’m on a SIMO plan. Will I be affected by the CPI price increase?

No. The April 2024 CPI +3.9% adjustment will only apply if you’ve upgraded to or purchased a new iD Mobile phone plan on or after 1st November 2022 and before 1st February 2024.

What if I have a discount on my monthly plan?

If you have a discount, it won't change. The price adjustment is applied to your original monthly plan cost, and your discount is applied afterwards.

What happens if I upgrade to another plan?

You won't get a CPI +3.9% price adjustment in 2024 if you’ve upgraded to a new plan on or after the 1st of February 2024. However, a CPI +3.9% adjustment will apply in 2025.

Can I cancel my iD plan?

We’d love you to stay but yes, you can cancel your plan by giving us 30 days' notice. Please note: You may need to pay an early termination charge if you cancel before the end of your contract. You can cancel your plan and check any possible early termination charges in the iD Mobile app.

How can I check my bill?

The CPI +3.9% adjustment will appear on your April bill. To view your latest bill, sign into the free iD Mobile App or visit My Account online, then go to 'Billing', 'Current month'.

I upgraded or purchased my iD plan before 1st November 2022. Will the price of my plan adjust by CPI +3.9%?

No. Your plan will instead adjust by RPI only.
