Retail Price Index

Everything you need to know about the RPI Increase

What is the Retail Price Index?

The Retail Price Index (RPI) is a measure of inflation, which is the rate at which prices for goods and services are rising. The RPI rate is published by the Office for National Statistics.

How does the RPI affect my iD Mobile plan?

Your monthly line rental cost will be adjusted each April by the RPI rate published in February. Price adjustments do not affect add-ons or additional charges.

For 2023, the RPI rate is +13.4%.

Does the 2023 RPI increase apply to me?

The RPI increase will apply if you've upgraded or purchased a new iD Mobile 24-month handset plan on or after 1st May 2021 and before 1st November 2022.

If you are affected by the 2023 price adjustments, you'll receive a text from us in March 2023 confirming the exact adjustment that will be applied to your April 2023 bill onwards.

RPI FAQs

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, our value-focused offering will remain one of the most competitive in the market, with our handset plans being £185 a year cheaper vs the major networks. We will continue to deliver great service and features to our customers, such as data rollover, inclusive roaming and the UK’s fastest 5G at no extra cost.

Why is RPI (Inflation) so high this year?

The cost of living has been increasing across the UK, resulting in the highest inflation levels for 30 years.

As RPI reflects the year-on-year difference in the price of goods and services for both companies and consumers, RPI has increased over the past year, from 7.8% in Feb 2022 to 13.4% in Feb 2023.

How have you calculated the rate of adjustment on my plan?

We've used the RPI rate of 13.4% published in February 2023. This is a measure of the average change in prices for consumers across the country over the last 12 months.

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 price plan charge, and your discount is applied afterwards.

What happens if I upgrade to another plan?

You won't get an RPI price adjustment this year if you’ve upgraded to a new plan on or after the 1st of February 2023. However, an RPI adjustment will apply in 2024.

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 RPI adjustment will appear on your April bill. To view your latest bill, login to the free iD Mobile App or visit My Account online, then go to 'Billing', 'Current month'.
