Annual price changes and CPI

Each year we have an annual price rise. If you're a new customer or re-contracting mobile, broadband or landline, you’ll see new terms and conditions that tell you that your prices will increase by the Consumer Price Index (CPI) rate of inflation each year.

Mobile and broadband customers who signed up or re-contracted on or after 17 January 2020 will receive their first CPI price rise in March 2021. Mobile and broadband customers who signed up or re-contracted between 11 January 2019 and 16 January 2020, will receive their first CPI price rise in March 2020.

Landline customers, if you have a phone or call plan or calling features, these will increase by CPI from March 2020 in line with your current terms.

Each year we will adjust the amount you pay per month for your plan(s) according to the Consumer Price Index (CPI) rate of inflation. This rate is announced in January each year and we will adjust your bill by this amount in March of the same year. The CPI rate announced in January 2020 is 1.3 per cent, so your monthly payments from March 2020 will increase by 1.3 per cent.

This reflects the increase in the costs to run and invest in the network and service that we provide.

The Consumer Price Index (CPI) is a measure of whether the cost of goods and services is going up or down based on average price changes from across several industries. A new index is published every month. There’s lots more information on the Office for National Statistics website, search ‘CPI ONS’.

Starting in March 2020, the price you pay each month for your mobile, broadband and landline services will be adjusted each year, according to the CPI rate of inflation. We’ll use the rate published in January. And we’ll change your monthly price from March of the same year.

The CPI rate announced in January 2020 is 1.3 percent, which is the rate your monthly plan price(s) from March 2020 will increase by. For example, this means a monthly price of £40 will go up to £40.52 in March 2020.

We’ll be in touch to let you know how much the price of your BT service(s) will change.

Your broadband, mobile and landline monthly plan prices will go up in line with any change in the rate of CPI. Some of our extra charges, like out-of-allowance calling rates and your optional add-ons, will go up in line with CPI too. But our mobile add-ons and calls, data and text prices are not increasing. And many of our landline and broadband products are also not changing in price. Have a look in the tariff guide for details.

The price of our pay monthly plans increases in line with CPI so we can keep pace with inflation. This reflects the increase in the costs to run and invest in our network and service we provide you, and allows us to invest in new technology and make sure we give you the best possible service.

If you have broadband, mobile or a landline with us, the increase to the price you pay for your plan(s) will take into account any discounts you get. So the price you pay each month will go up by the amount in the CPI.

If you have BT Broadband with a mobile plan (and therefore the £5 mobile discount), we’ll work out CPI in the same way - by applying CPI to the discounted monthly price you pay, whether you’re in or out of contract.

If you only have mobile with us (and not BT Broadband), it’s slightly different. We’ll work out CPI using the monthly price you pay, minus £5 and then add that amount to your monthly price. This is to make sure the price change is the same for all our mobile customers on the same plan.

For example, if you pay £13 a month for your mobile plan, we’d work out the price increase by applying the CPI percentage to £8 (£13 minus £5). We’d then add that price increase amount to the £13 monthly price.

You can log into bt.com/mybt to see more information about your price plan(s).

If you’re within your minimum term when the prices go up, you can cancel your contract. But there will be a fee for cancelling early. If you’re outside of your contract period you can end your contract at any time without any fees.

It depends when you upgraded. The table below sets out when your first CPI price rise will be.
