    CPI Plus 3.9% Guide

    Find out about CPI plus 3.9% price increases.

    Our guide will take you through the what, when and how of CPI plus 3.9% increases and how they’ll apply to your services.

    Will these price increases apply to me?

    These price increases will apply to you unless you are currently in a fixed price contract minimum term.

    For customers who are in a fixed price contract minimum term, with the exception of BT Sport, these price increases will only apply to you once your minimum term ends. Please note that if you signed up to a BT Sport service on or after 9th December, the price of your BT Sport service will increase by CPI plus 3.9% as set out in your terms and conditions and as explained in more detail below.

    What's CPI?

    The Consumer Price Index (CPI) rate is a figure released by the Office for National Statistics. The CPI is used for purposes such as uprating pensions, wages and benefits and can help in the understanding of inflation on family budgets. CPI measures the average price change as a percentage for a basket of 700 different goods and services which households buy.

    What prices will increase by CPI plus 3.9%?

    Our broadband, line rental, call plans, some call charges and BT Sport services where that BT Sport service was signed up to on or after 9th December 2020 (including the BT Sport App, BT Sport Channel Pack through YouView TV from Plusnet, BT Sport over Sky and BT Sport over Sky HD) will go up in price in line with CPI plus 3.9% on or after 1st March every year from March 2022.

    How will the CPI plus 3.9% price increases work?

    On or after 1st March every year from March 2022, we'll take the CPI percentage rate published by the Office for National Statistics in January of that year and add an extra 3.9% to the rate. We'll increase the monthly price of broadband, line rental, call plans, call charges and BT Sport services where that BT Sport service was signed up to on or after 9th December 2020 by the total percentage figure.

    If the published CPI percentage rate is negative, we'll only increase your prices by 3.9% in the relevant year.

    The calculated increase will be rounded up to the nearest whole pence.

    Where you buy more than one service from us and each is subject to the price increase, the amount of the increase is calculated on each service separately. If you receive a discount on your price, the increase will be applied to this amount.

    Here's an example to show how the price rise works.

    Let's say:

    You have Unlimited Fibre Broadband and line rental and an Evening and Weekend UK & Mobile call plan. The price of your package is made up of:

    • Unlimited Fibre Broadband - £16.98 per month
    • Line rental - £21.22 per month
    • Evening and Weekend UK & Mobile Call plan - £5.23 per month
    • Your total monthly price = £43.43
    • The CPI rate published in January 2022 is 0.9%
    • The CPI rate published in January 2023 is 1.2%

    .

    Date Monthly Price
    Monthly price up to June 2021 £43.43
    Monthly price from June 2021 to Feb 2022 £45.52

    Worked out as follows:

    Unlimited Fibre Broadband £16.98 per month plus 4.8% (the 0.9% CPI rate published in January 2022 plus 3.9%)

    = £16.98 x 4.8% = £0.82

    £16.98 + £0.82 = £17.80 per month

    Line rental £21.22 per month plus 4.8% (the 0.9% CPI rate published in January 2022 plus 3.9%)

    = £21.22 x 4.8% = £1.02

    £21.22 + £1.02 = £22.24 per month

    Evening and Weekend UK & Mobile Call plan £5.23 per month plus 4.8% (the 0.9% CPI rate published in January 2022 plus 3.9%)

    = £5.23 x 4.8% = £0.25

    £5.23 + £0.25 = £5.48 per month

    Total monthly price:

    £17.80 + £22.24 + £5.48 = £45.52
    Some call charges will also increase in price. See What about changes to call charges? for more details.
    Monthly price from March 2022 to Feb 2023 £47.84

    Worked out as follows:

    Unlimited Fibre Broadband £17.80 per month plus 5.1% (the 1.2% CPI rate published in January 2023 plus 3.9%)

    = £17.80 x 5.1% = £0.91

    £17.80 + £0.91 = £18.71 per month

    Line rental £22.24 per month plus 5.1% (the 1.2% CPI rate published in January 2023 plus 3.9%)

    = £22.24 x 5.1% = £1.13

    £22.24 + £1.13 = £23.37 per month

    Evening and Weekend UK & Mobile Call plan £5.48 per month plus 5.1% (the 1.2% CPI rate published in January 2023 plus 3.9%)

    = £5.48 x 5.1% = £0.28

    £5.48 + £0.28 = £5.76 per month

    Total monthly price:

    £18.71 + £23.37 + £5.76 = £47.84
    Some call charges will also increase in price. See What about changes to call charges? for more details.

    When will you tell me my prices are going up?

    We'll need to wait for the CPI rate to be published each January to work out how it will change your price. We'll aim to let you know before we increase our prices.

    Does CPI Plus 3.9% apply to fixed price contracts?

    If you've signed up to one of our fixed price contracts and you're still within your minimum term it will do exactly what you'd expect. Your broadband and line rental prices won't change during the minimum term of your contract. Please note, if you have a fixed price contract, and have signed up to any BT Sport service on or after 9th December 2020 your BT Sport service will go up in price in line with CPI plus 3.9% on or after 1st March every year from March 2022 as set out in this Guide.

    If you're a fixed price contract customer, once your minimum term ends, the below terms will apply-

    • Your broadband, line rental and any call plan you may have will increase to the then applicable out of contract price set out in our Price Guide at that time; and
    • Your terms and conditions will include CPI plus 3.9% price changes. This means the price for broadband, line rental, call plans, call charges and BT Sport services where that BT Sport service was signed up to on or after 9th December 2020 will be increased on or after 1st March every year from March 2022 by the Consumer Price Index rate of inflation published in January of that year plus 3.9%.

    When your fixed price contract minimum term is coming to an end, we'll send you an end of contract reminder and offer you an account review.

    What about changes to call charges?

    Some call charges will go up in price in line with CPI plus 3.9% on or after 1st March every year from March 2022. Please see our call charges for details.

    Here's an example to show how call charge price increases work

    A call to 01, 02 and 03 costs: 24.06p set up fee and 15.69 pence per minute rate.

    • The CPI rate published in January 2022 is 0.9%
    • The CPI rate published in January 2023 is 1.2%

    .

    Date Motnhly Price
    Price up to June 2021 24.06p set up fee

    15.69 pence per minute rate
    Price from June 2021 to Feb 2022 25.21p set up fee

    16.44 pence per minute rate

    Worked out as follows:

    Set up fee 24.06p per call plus 4.8% (the 0.9% CPI rate published in January 2022 plus 3.9%)

    = 24.06p x 4.8% = 1.15p

    24.06p + 1.15p = 25.21p set up fee

    Pence per minute rate 15.69p plus 4.8% (the 0.9% CPI rate published in January 2022 plus 3.9%)

    = 15.69p x 4.8% = 0.75p

    15.69p + 0.75p = 16.44 pence per minute rate
    Price from March 2022 to Feb 2023 26.50p set up fee

    17.28 pence per minute rate

    Worked out as follows:

    Set up fee 25.21p per call plus 5.1% (the 1.2% CPI rate published in January 2023 plus 3.9%)

    = 25.21p x 5.1% = 1.29p

    25.21p + 1.29p = 26.50p set up fee

    Pence per minute rate 16.44p plus 5.1% (the 1.2% CPI rate published in January 2023 plus 3.9%)

    = 16.44p x 5.1 % = 0.84p

    16.44p + 0.84p = 17.28 pence per minute rate

    Do the price increases apply to all BT Sport services?

    For any BT Sport service signed up to on or after 9th December 2020 the price will increase in line with CPI plus 3.9% on or after 1st March every year from March 2022.

    This includes the BT Sport App, BT Sport Channel Pack through YouView TV from Plusnet, BT Sport over Sky and BT Sport over Sky HD.

    Here's an example to show how the price rise works for one of our BT Sport services.

    Let's say:

    • You signed up to the BT Sport App on or after 9th December 2020 at £15.69 a month
    • The CPI rate published in January 2022 is 0.9%
    • The CPI rate published in January 2023 is 1.2%

    .

    Date Monthly Price
    Monthly price up to June 2021 £15.69
    Monthly price from June 2021 to Feb 2022 £16.44

    Worked out as follows:

    BT Sport App £15.69 per month plus 4.8%
    (the 0.9% CPI rate published in January 2022 plus 3.9%)

    = £15.69 x 4.8% = £0.75

    £15.69 + £0.75 = £16.44 per month
    Monthly price from Mar 2022 to Feb 2023 £17.28

    Worked out as follows:

    BT Sport App £16.44 per month plus 5.1%
    (the 1.2% CPI rate published in January 2023 plus 3.9%)

    = £16.44 x 5.1% = £0.84

    £16.44 + £0.84 = £17.28 per month

    What about changes to early termination charges?

    Early termination charges will also be subject to CPI plus 3.9% price rises on or after 1st March every year from March 2022.

    Please see our Price Guide for details.

    Can I cancel my contract because of these changes?

    If we're only putting up the price of broadband, line rental, call plans, call charges and BT Sport in line with the CPI plus 3.9% and you choose to cancel because of that, you'll still need to pay any early termination charges if you're still within your minimum term. This is because the amount we can increase your price by is fixed to any increase in CPI plus 3.9% and we'll have made the price increase clear when you signed up and you'll have agreed to it in our terms and conditions.

    If we put up our prices for any other reason though, you might be able to end your contract early without paying any charge.

    Will these prices apply to me?

    These price increases will apply to you unless you are currently in a fixed price contract minimum term.

    For customers who are in a fixed price contract minimum term, these price increases will only apply to you once your minimum term ends.

    What's CPI?

    The Consumer Price Index (CPI) rate is a figure released by the Office for National Statistics. The CPI is used for purposes such as uprating pensions, wages and benefits and can help in the understanding of inflation on family budgets. CPI measures the average price change as a percentage for a basket of 700 different goods and services which households buy.

    Which prices will increase by CPI plus 3.9%?

    Our broadband, line rental, call plans and some call charges will go up in price in line with CPI plus 3.9% on or after 1st March every year from March 2022.

    For any customer who signs-up or takes a new contract on or after 15th March 2021, early termination charges will also increase in line with CPI plus 3.9%

    How will the CPI plus 3.9% price increases work?

    On or after 1st March every year from March 2022, we'll take the CPI percentage rate published by the Office for National Statistics in January of that year and add an extra 3.9% to the rate. We'll increase the monthly price of broadband, line rental, call plans and call charges by the total percentage figure.

    If the published CPI percentage rate is negative, we'll only increase your prices by 3.9% in the relevant year.

    The calculated increase will be rounded up to the nearest whole pence.

    Where you buy more than one service from us and each is subject to the price increase, the amount of the increase is calculated on each service separately. The price increase is applied to the ex VAT price and if you receive a discount on your price, the increase will be applied to the discounted ex VAT price.

    Here's an example to show how the price rise works.

    Let's say:

    You have Unlimited Business Fibre Broadband and line rental on a 24 month contract and Business Unlimited UK calls. The price of your package is made up of:

    • Unlimited Business Fibre Broadband - £4.50. per month

    Worked out as follows:

    Unlimited Business Fibre Broadband £4.50 per month plus 5.1% (the 1.2% CPI rate published in January 2022 plus 3.9%)

    = £4.50 x 5.1% = £0.23

    £4.50 + £0.23 = £4.73 per month

    Line rental £17.50 per month plus 5.1% (the 1.2% CPI rate published in January 2022 plus 3.9%)

    = £17.50 x 5.1% = £0.90

    £17.50 + £0.90 = £18.40 per month

    Business Unlimited UK calls £6.50 per month plus 5.1% (the 1.2% CPI rate published in January 2022 plus 3.9%)

    = £6.50 x 5.1% = £0.34

    £6.50 + £0.34 = £6.84 per month

    Total monthly price:

    £4.73 + £18.40 + £6.84 = £29.97
    Some call charges will also increase in price. See What about changes to call charges? for more details.
    Monthly price from March 2023 to Feb 2024 £31.60

    Worked out as follows:

    Unlimited Fibre Broadband £4.73 per month plus 5.4% (the 1.5% CPI rate published in January 2023 plus 3.9%)

    = £4.73 x 5.4% = £0.26

    Line rental £18.40 per month plus 5.4% (the 1.5% CPI rate published in January 2023 plus 3.9%)

    = £18.40 x 5.4% = £1.00

    Business Unlimited UK calls £6.84 per month plus 5.4% (the 1.5% CPI rate published in January 2023 plus 3.9%)

    = £6.84 x 5.4% = £0.37

    £6.84 + £0.37 = £7.21 per month

    Total monthly price:

    £4.99 + £19.40 + £7.21 = £31.60
    Some call charges will also increase in price. See What about changes to call charges? for more details.

    When will you tell me my prices are going up?

    We'll need to wait for the CPI rate to be published in January from 2022 onwards to work out how it will change your price. We'll always let you know before we increase our prices.

    Does CPI plus 3.9% apply to fixed price contracts?

    If you've signed up to one of our fixed price contracts and you're still within your minimum term it will do exactly what you'd expect. Your broadband and line rental prices won't change during the minimum term of your contract.

    If you're a customer whose fixed price contract minimum term ends (or has ended) on or after 8th June 2021, the below terms will apply when that minimum term ends:-

    • Your broadband and line rental will increase to the then applicable out of contract price set out in our Charges Schedule at that time; and
    • Your terms and conditions will include CPI plus 3.9% price changes. This means the price for broadband, line rental, call plans, call charges will be increased on or after 1st March every year from March 2022 by the Consumer Price Index rate of inflation published in January of that year plus 3.9%.

    When your fixed price contract minimum term is coming to an end, we'll send you an end of contract reminder and offer you an account review.

    What about changes to call charges?

    Some call charges will go up in price in line with CPI plus 3.9% on or after 1st March every year from March 2022. Please see our Charges Schedule for details.

    Here's an example to show how call charge price increases work

    A call to 01, 02 and 03 costs: £0.05 set up fee and £0.03 pence per minute rate.

    • The CPI rate published in January 2022 is 1.2%
    • The CPI rate published in January 2023 is 1.5%

    £0.03 pence per minute rate
    Price from March 2022 to Feb 2023 £0.06 set up fee

    £0.04 pence per minute rate

    Worked out as follows:

    Set up fee £0.05 per call plus 5.1% (the 1.2% CPI rate published in January 2022 plus 3.9%)

    = £0.05 x 5.1% = £0.01

    £0.05 + £0.01 = £0.06 set up fee

    Pence per minute rate £0.03 plus 5.1% (the 1.2% CPI rate published in January 2022 plus 3.9%)

    = £0.03 x 5.1% = £0.01

    £0.03 + £0.01 = £0.04 pence per minute rate
    Price from March 2023 to Feb 2024 £0.07 set up fee

    £0.05 pence per minute rate

    Worked out as follows:

    Set up fee £0.06 per call plus 5.4% (the 1.5% CPI rate published in January 2023 plus 3.9%)

    = £0.06 x 5.4% = £0.01

    £0.06 + £0.01 = £0.07 set up fee

    Pence per minute rate £0.04 plus 5.4% (the 1.5% CPI rate published in January 2023 plus 3.9%)

    = £0.04 x 5.4 % = £0.01

    £0.04 + £0.01 = £0.05 pence per minute rate

    What about changes to early termination charges?

    For any customer who signs-up or take a new contract on or after 15th March 2021, early termination charges will also be subject to CPI plus 3.9% price rises on or after 1st March every year from March 2022.

    Please see our Charges Schedule for details.

    Can I cancel my contract because of these changes?

    If we're only putting up the price of broadband, line rental, call plans and call charges in line with the CPI plus 3.9% and you choose to cancel because of that, you'll still need to pay any early termination charges if you're still within your minimum term. This is because the amount we can increase your price by is fixed to any increase in CPI plus 3.9% and we'll have made the price increase clear when you signed up and you'll have agreed to it in our terms and conditions.

    These price increases apply to all Plusnet Mobile customers.

    What's CPI?

    The Consumer Price Index (CPI) rate is a figure released by the Office for National Statistics. The CPI is used for purposes such as uprating pensions, wages and benefits and can help in the understanding of inflation on family budgets. CPI measures the average price change as a percentage for a basket of 700 different goods and services which households buy.

    How will you work out how much you'll put up your prices by?

    On or after 1st March every year from March 2022, we'll take the CPI percentage rate published by the Office for National Statistics in January of that year and add an extra 3.9% to the rate. We'll increase the monthly price of your mobile plan by the total percentage figure.

    If the published CPI figure is negative, we'll only increase your price by 3.9% in the relevant year.

    The calculated increase will be rounded up to the nearest whole pence.

    Where you buy more than one service from us and each is subject to the price increase, the amount of the increase is calculated on each service separately. If you receive a discount on your plan price this will not change. The price increase is applied to the standard plan price and then the same discount as before is applied afterward to calculate your new plan price.

    Here's an example to show how the price rise works.

    Let's say:

    • You have a mobile plan that's £10 a month
    • The CPI rate published in April 2021 is 0.9%
    • The CPI rate published in January 2022 is 1.2%

    .

    Date Monthly Price
    Monthly price up to June 2021 £10
    Monthly price from June 2021 to Feb 2022 £10.48

    Worked out as follows:

    SIM only plan £10 per month plus 4.8%

    (the 0.9% CPI rate published in April 2021 plus 3.9%)

    = £10.00 x 4.8% = £0.48

    £10.00 + £0.48 = £10.48 per month
    Monthly price from Mar 2022 to Feb 2023 £11.01 Worked out as follows:

    SIM only plan £10.48 per month plus 5.1%

    (the 1.2% CPI rate published in January 2022 plus 3.9%)

    £10.48 x 5.1% = £0.53

    £10.48 + £0.53 = £11.01 per month

    When will you tell me that your prices are going up?

    We'll need to wait for the CPI rate to be published every January from 2022 onwards to work out how it will change your price. We'll always let you know before we increase our prices.

    What about changes to early termination charges?

    For any customer who signs-up or take a new contract with Plusnet Mobile and/or changes their Plusnet Mobile plan on or after 7th October 2020, early termination charges will also be subject to CPI plus 3.9% price rises on or after 1st March every year from March 2022.

    Can I cancel my mobile contract because of these changes?

    If we're only putting up prices in line with the CPI plus 3.9% and you choose to cancel because of that, you'll still need to pay any early termination charges if you're still within your minimum term. This is because the amount we can increase your price by is fixed to any increase in CPI plus 3.9% and, we'll have made the price increase clear when you signed up and you'll have agreed to it in our Mobile Terms.

    If we put up our prices for any other reason though, you might be able to end your contract early without paying any charges.
