How much will my broadband go up mid-contract? UK price rises explained

If you signed a broadband deal recently, the annual increase is now most likely a fixed amount rather than a percentage. For the biggest providers that means somewhere between £2 and £6 a month added to your bill each spring, usually on 31 March or 1 April. On a broadband-only plan with BT, EE, Plusnet, Virgin Media, TalkTalk or Hyperoptic, expect around £4 a month. Vodafone and Three sit slightly lower at £3.50. Smaller providers such as toob (£2) and Onestream (£2.75) charge less again.

That is the short answer. The detail matters, though, because how much you pay depends heavily on when you signed up, and because a small number of providers do not raise prices mid-contract at all.

How mid-contract broadband price rises work

You would be forgiven for thinking the monthly price you agree to is fixed for the length of your contract. For most customers, it is not. The majority of the biggest providers, including BT, EE, Vodafone, Virgin Media and TalkTalk, have written price variation clauses into their terms that let them increase your bill once a year, normally around spring, even though your contract might run for 18 or 24 months.

There is currently nothing in broadband comparable to a fixed energy tariff that locks your price. As long as a provider notifies you and gives fair notice of the increase, no rules are broken. The standard notice period is 30 days, and you are far more likely to be told by email or text than by post, so check your inbox and spam folder around late winter.

How much will your bill actually go up?

For anyone signing a new contract today, the increase is a flat pound-and-pence figure. Here is how the major providers compare for increases applying from 2027 onwards.

Provider	Fixed annual increase	Applies from
BT Broadband	£4 (broadband only), £6 (broadband and TV)	31 March 2027
EE Broadband	£4	31 March 2027
Plusnet	£4	31 March 2027
Virgin Media	£4 (all packages)	1 April 2027
TalkTalk	£4	1 April 2027
Hyperoptic	£4	1 April 2027
Vodafone	£3.50	1 April 2027
Three Broadband	£3.50	1 April 2027
Fibrely	£3	1 April 2027
The One Broadband	£3	1 April 2027
Onestream	£2.75	1 April 2027
toob	£2	1 April 2027
Gigaclear	£1.50 to £3	To be confirmed
NOW Broadband	Around £3 average	To be confirmed
Sky Broadband	Around £3 average	To be confirmed

The important point about a flat increase is that it compounds. TalkTalk gives a clear worked example: sign up to a 24-month plan at £28 a month on or after 16 November 2025 and the £4 rise takes you to £32 from April 2026, then to £36 from April 2027, and so on until the contract ends.

A worked example

Say you are paying £30 a month for broadband with a £4 annual increase.

• Year one: £30
• After the first April rise: £34
• After the second April rise: £38

That is £8 a month more than your headline price by the second year, or roughly £96 extra across twelve months compared with what you first signed up for. On a percentage-based deal you would multiply your monthly cost by the rate instead, which is why the flat figure hits cheaper packages harder in proportional terms.

The move from inflation-linked to fixed price rises

Until recently, most annual increases were tied to inflation. Providers used the Consumer Prices Index (CPI), often with an extra percentage added on top. TalkTalk, for instance, used CPI plus 3.7%; in 2024 the CPI figure was 4%, so the total rise came to 7.7% of the contract price.

That changed for new contracts. Since January 2025, providers can no longer use inflation-linked percentage rises in new deals. Any mid-contract increase must instead be clearly stated in pounds and pence at the point of sale, so you can see exactly what you will pay before you commit.

The cut-off date depends on the provider and on when your contract started:

• BT, EE and Plusnet: contracts from 10 April 2024
• Vodafone: contracts from 2 July 2024
• TalkTalk: contracts from 12 August 2024
• Three Broadband: contracts from 1 September 2024
• Virgin Media: contracts from 9 January 2025

If you signed before your provider's date, you may still be on the old inflation-linked structure. For those customers this year, Virgin has applied a 7.5% rise, with an average of 6.2% to 6.4% for most other well-known providers. TalkTalk customers who joined between 12 August 2024 and 15 November 2025 are on a £3 fixed rise, while those who joined before 12 August 2024 and are still in contract remain on CPI plus 3.7%.

When do the increases happen?

Broadband and mobile prices tend to rise once a year, and most providers apply the change on 31 March or 1 April. Because the increase compounds, knowing your provider's date helps you plan. If your minimum term is due to end shortly after a spring rise, that is often the moment to review your options rather than roll on to a more expensive standard rate.

What Ofcom rules say about price rises

Ofcom's rules require providers to make any potential price rises clear to new customers when they sign up, and to express them in real money rather than as a percentage. This is the rule that took effect for new contracts from early 2025 and replaced the old CPI or RPI plus a percentage model.

What the rules do not do is cap the increase. There is currently no limit on how much extra a provider can charge, so with every year on the same deal you pay more. Providers must also send an end-of-contract notification between 10 and 40 days before your minimum term ends, which is a useful prompt to shop around.

Can you cancel your contract without a fee?

This is where expectations often outrun reality. If a price rise is clearly written into your contract and was explained upfront, it usually does not give you the right to leave without paying early exit charges. Under the new fixed-rise regime, the increase is baked into the deal you agreed to, so the flat annual rise is not normally grounds for a penalty-free exit.

There is a narrower situation where you can walk away. If a provider applies a mid-contract rise that was not allowed for in your contract, or changes how prices are calculated, that may give you the right to leave penalty-free.

Some providers go further by choice. Sky and NOW Broadband do not include price rises in their contracts, which means customers can leave within 31 days of being notified of a hike. That does not stop a rise being applied, but it does give you an escape route if one is.

If you are simply mid-contract and want out, weigh any early termination fee against the savings a new deal would bring. Sometimes paying the fee still leaves you better off; sometimes it does not.

How to reduce or avoid a price increase

Time your switch. If you are already out of contract, you can usually switch without penalty. If your deal ends in the next 30 to 60 days, start comparing now so you do not lapse on to a pricier standard tariff. Ofcom's One Touch Switch process has made moving provider more straightforward in most cases.

Read the small print before you sign. Look for a price variation clause, references to CPI on older-style deals, or a stated fixed annual increase on newer ones. These details usually sit in the key facts summary or full terms rather than in the headline price. Phrases like "annual price rise" or "prices may increase each year" are the signal.

Try to haggle. When your rise lands or your deal is ending, it is worth calling to renegotiate. A simple approach:

1. Note your current monthly price and what it rises to after the increase.
2. Find two or three cheaper deals for a similar speed at your postcode.
3. Tell your provider you are considering leaving and quote the better price you have found.
4. Ask whether they can match it or improve your current rate.

Consider a fixed-price deal. Some providers promote a "Fixed Price Promise", and Zen offers a Contract Price Promise under which the price you agree at sign-up is the price you pay for the full contract, with no CPI or in-contract rises. Many smaller and local networks offer similar guarantees. If annual hikes frustrate you, filtering for these deals sidesteps the problem entirely.

Help if you're struggling to pay

If the cost is becoming hard to manage, it is worth checking whether you qualify for a cheaper deal or a social tariff, and speaking to your provider before you fall behind. Switching once you are free to do so, or negotiating a better rate, are the most direct ways to bring an inflated bill back down.

Frequently asked questions

How much will my broadband go up mid-contract? On a new contract with a major provider, expect a fixed increase of roughly £2 to £6 a month each spring. BT, EE, Plusnet, Virgin Media and TalkTalk apply £4 for broadband-only plans; BT charges £6 on broadband and TV bundles. Vodafone and Three apply £3.50.

Why does my broadband price keep rising? Most providers write annual increases into their contracts, saying the money funds network maintenance and investment. The rise applies each year for as long as you stay on the deal.

How are mid-contract price rises calculated? On contracts signed since early 2025, it is a flat pound-and-pence amount stated when you sign up. On older contracts it may still be a percentage based on CPI, sometimes with an extra amount added on top.

Can I cancel my broadband contract if the price goes up? Usually not without paying an early exit fee, if the rise was clearly set out in your contract. You can leave penalty-free if the provider applies a rise that was not allowed for, or changes how prices are calculated. Sky and NOW Broadband customers can leave within 31 days of being told of a hike.

When do broadband price rises usually happen? Most providers apply them on 31 March or 1 April, with at least 30 days' notice by email or text.

Are there deals with no mid-contract rises? Yes. Sky and NOW Broadband do not include rises in their contracts, Zen offers a Contract Price Promise for the full contract term, and many smaller local networks advertise a fixed price guarantee.
