Ofcom proposes ban on inflation-linked mid-contract price rises

Ofcom also reveals that take-up of social tariffs more than doubled in the last year, but millions of eligible customers remain unaware of them

Telecoms customers must be told upfront in pounds and pence about any price rises their provider includes in their contract, under new consumer protection plans set out today by Ofcom.

With most major phone, broadband and pay TV companies now including mid-contract price rises linked to uncertain future inflation, we are concerned that customers’ contracts do not provide sufficient certainty about the prices they will pay.

So Ofcom are proposing to introduce tougher protections for customers by banning this practice.

Confusing price rise terms risk undermining competitive market

Competition helps keep prices down. Although some broadband prices have increased this year, over the last five years, average prices for broadband and mobile services in the UK have fallen in real terms. At the same time, companies have been investing in upgrading their networks, while average speeds and data use have increased.[1]

However, for competition to work, consumers must be able to shop around with confidence.

In recent years, pricing practices where providers impose an annual rise linked to unpredictable future inflation, plus an additional percentage of typically 3.9%, have become significantly more widespread, undermining customers’ understanding of what they will pay.

Timeline: Introduction of inflation-linked price variation terms including an additonal fixed percentage

What we have found

Our analysis of providers’ data shows that as of April 2023 four in ten (11 million) broadband customers and over half of mobile customers (36 million) were on contracts subject to inflation-linked price rises. We estimate that these numbers may grow further, to around six in ten of both broadband and mobile customers, as Three and Virgin Media apply inflation-linked in-contract price rise terms to more of their customers’ contracts during 2023/24.

However, awareness and understanding of these terms is very low.  More than half (55%) of broadband customers and pay monthly mobile customers (58%) do not know what inflation rates such as CPI and RPI measure. And of those who are with providers that use inflation-linked price rises, very few broadband (16%) and mobile customers (12%) were both aware of the price rise and able to identify that it was inflation-linked with an additional percentage.[2]

We also found that even when people do consider future inflation-linked price rises when choosing a contract, they often do not understand them fully and find it difficult to estimate what the impact could be on their payments.

Between January and October 2023, Ofcom received over 800 complaints related to price rises – almost double the volume of complaints received during the same period in 2021 – many of which highlighted uncertainty created by inflation-linked price rises.

Our conclusions

We have provisionally concluded that inflation-linked mid-contract price rise terms can cause substantial amounts of consumer harm by complicating the process of shopping for a deal, limiting consumer engagement, and making competition less effective as a result.

These terms also require customers to unfairly assume the risk and burden of financial uncertainty from inflation, with tangible impacts on their ability to manage costs at a time when household budgets are already stretched to the limit.

Toughening our rules

To tackle this problem, we propose to introduce a new rule requiring that any price written into a customer’s contract would need to be set out in pounds and pence, prominently and transparently, at the point of sale. That includes being clear about when any changes to prices will occur.

This would prevent providers from including inflation-linked, or percentage-based, price rise terms in all new contracts.

Before and after diagram

Dame Melanie Dawes, Ofcom’s Chief Executive, said: “At a time when household finances are under serious strain, customers need prices to be crystal clear. But most people are left confused by the sheer complexity and unpredictability of inflation-linked price rise terms written into their contract, which undermines customers’ ability to shop around.

“Our tougher protections would ban this practice once and for all, giving customers the clarity and certainty they need to secure the best deal for their needs and budget.”

Next steps

We are consulting on this proposed new requirement until 13 February 2024, and plan to publish our final decision in spring 2024.

Subject to responses, we intend for the new rule to come into effect four months after the publication of our final decision. This period reflects our concern about the scale of consumer harm balanced against the need to give providers sufficient time to make the necessary changes to their processes and business plans.

Enforcement action

Separately, Ofcom have been investigating whether phone and broadband companies complied with our previous rules between March 2021 and June 2022. We have found that a small number of providers may not have given some customers clear information about price rises at the right time, creating a potential compliance concern.

We have discussed these concerns with the relevant providers and secured refunds for some affected customers. We will continue to discuss our remaining concerns with these providers, escalating to separate, targeted enforcement action if necessary.

Social tariff take-up doubles in a year

Ofcom has also today published its annual Pricing Trends report, which this year includes the latest take-up and awareness figures for social tariffs.

Social tariffs are cheaper broadband and phone packages for people claiming Universal Credit, Pension Credit and some other benefits. Some providers call them ‘essential’ or ‘basic’ broadband.

Take-up of social tariffs increased to 380,000 in September 2023, up from 147,000 a year earlier, meaning more customers are benefitting from the savings the tariffs offer. However, awareness among eligible customers remains a challenge. Just over half (55%) of eligible households remain unaware of social tariffs; and while take-up is improving, it remains low as a proportion of all eligible households (8.3%).

For the first time, we have published take-up figures for each of the largest providers of broadband social tariffs.

Social tariff take-up: February 2022 to September 2023 (000s)



Bar chart showing take up of social tariff from February 2022 to September 2023“No data” indicates that we did not collect social tariff take-up figures in a particular month: these values are estimated and do not represent actual take-up.

BT has the largest share of broadband customers taking a social tariff (72%), followed by Sky (13%), Virgin Media (6%), Vodafone (4%), KCOM (1%) and Shell Energy (0.3%).

These proportions are partly a reflection of the length of time over which different social tariff products have been available. TalkTalk is the only major broadband provider not to offer a social tariff.

Millions of mobile customers could save over £200 a year by switching when out of contract, Which? finds

After eye-watering price hikes came into effect earlier this month, new Which? research has found that some Big Four mobile customers could save more than £200 a year by switching when their contract ends. 

Using data from its most recent mobile survey, the consumer champion has calculated how much out-of-contract customers of the Big Four providers – EE, Three, O2 and Vodafone – could save by switching to Which?’s top pick of low, medium and high data deals.

Which?’s survey found that out-of-contract Big Four customers pay an average of £22.37 a month – significantly higher than the average £19.01 monthly bill across all providers – and in some cases could save more than £200 a year by switching away to cheaper deals.

When Which? checked this week, the consumer champion found a range of deals with highly-rated providers offering around low, medium and high data packages for under £14 a month – examples included Smarty’s 4GB for £5 deal and iD Mobile’s 200GB for £14 offer.

The average out-of-contract EE customer in the consumer champion’s survey pays £23.80 per month and could stand to make the biggest savings. By switching to Which?’s top low data pick – Smarty’s 4GB offer – they could potentially save £225.60 a year (£18.80 a month).

This is closely followed by out-of-contract Vodafone customers who pay an average of £22.20 per month according to Which?’s survey and could save £206.40 (£17.20 a month) by switching to Smarty’s 4GB offer.

Three and O2 customers would also stand to make significant savings. According to the consumer champion’s survey, out-of-contract Three and O2 customers pay an average of £21.50 a month and £21.30 a month respectively and could save £198 (£16.50 a month) and £195.60 (£16.30 a month) by switching to Smarty’s deal.

Big Four customers could also make significant savings by switching to Which?’s medium and high data picks – such as iD Mobile’s 20GB offer for £7 and iD Mobile’s 200GB offer for £14.

EE customers would again make the biggest savings – £201.60 a year (£16.80 a month) for switching to Which?’s medium data pick and £117.60 annually (£9.80 a month) for high data.

O2 customers would make the lowest savings – £171.60 a year (£14.30 a month) for medium data and £87.60 annually (£7.30 a month) for high data.

In the consumer champion’s recent mobile survey, over half (52%) said they only use up to 5GB a month – so many customers could make significant savings by switching to a cheap, low-data deal. With many providers pushing ahead with price hikes of up to 17 per cent, out-of-contract customers should switch quickly to cut costs.

However, not all customers can switch away so easily. Millions are trapped in a Catch-22 where they either have to accept price hikes of up to 17 per cent or pay exorbitant exit fees to leave the contract early. Which? has called on providers to allow all customers to leave without penalty if prices are hiked mid-contract but many are ploughing ahead with their existing plans regardless.

Rocio Concha, Which? Director of Policy and Advocacy, said: “Our findings show that some out-of-contract Big Four customers could save over £200 a year just by switching mobile providers. Anyone in that position should be thinking about making a switch or at least haggling for a much better deal from their current provider.

“However, millions will be trapped in costly contracts by exorbitant exit fees – and feeling the pain of eye-watering price increases of up to 17 per cent.

“Which? believes it’s absolutely critical that Ofcom’s review of inflation linked mid-contract hikes results in changes that ensure customers are never trapped in this situation again.”

How much EE customers could save

Out of contract EE customers pay the most on average, although those on bundled contracts may be eligible for a 10 per cent discount after being out of contract for three months.

EE out of contract survey average is £23.80 per month.

  • Low data pick: Smarty 4GB for £5 – potential savings of £18.80 per month
  • Medium data pick: iD Mobile 20GB for £7 – potential savings of £16.40 per month
  • High data pick: iD Mobile 200GB for £14 – potential savings of £9.80 per month

How much Three customers could save

Three does not apply any discount for out of contract customers, so they will continue to pay their full rate.

Three out of contract survey average is £21.50 per month.

  • Low data pick: Smarty 4GB for £5 – potential savings £16.50 per month
  • Medium data pick: iD Mobile 20GB for £7 – potential savings £14.50 per month
  • High data pick: iD Mobile 200GB for £14 – potential savings £7.50 per month

How much O2 customers could save

O2 offers split contracts, so the device and airtime parts of the contracts are charged separately. This means customers will not pay extra when their phone has been paid off, but it could still be worth shopping around for a cheaper Sim-only deal.

O2 out of contract survey average is £21.30 per month.

  • Low data pick: Smarty 4GB for £5 – potential savings £16.30 per month
  • Medium data pick: iD Mobile 20GB for £7 – potential savings £14.30 per month
  • High data pick: iD Mobile 200GB for £14 – potential savings £7.30 per month

How much Vodafone customers could save

Vodafone’s Evo customers will be in a similar situation to O2 customers, as their contracts are split. However, plenty of legacy customers – who joined Vodafone before Evo launched in June 2021 – will still be on bundled contracts and potentially paying extra.

Vodafone out of contract survey average is £22.20 per month.

  • Low data pick: Smarty 5GB for £4 – potential savings £17.20 per month
  • Medium data pick: iD Mobile 20GB for £7 – potential savings £15.20 per month
  • High data pick: iD Mobile 200GB for £14 – potential savings £8.20 per month

Right of replies

An EE spokesperson said: “We aim to make sure our customers are always on the best deal for them. We contact our customers near the end of their contract, and periodically while out of contract, to remind them of our latest deals. All out of contract EE customers are eligible for a 10% discount after being out of contract for three months.

“Customers can regularly track their data usage through the MyEE app. We’re the only network that makes sure you stay online and connected even when your monthly data allowance runs out, through our Stay Connected Data offering.”

Three declined to comment. 

A Virgin Media O2 spokesperson said: “Unlike the other mobile network operators, nearly a decade ago we launched contracts which automatically reduce customers’ bills as soon as they’ve finished paying for their handsets – so our customers are already saving big when their contract ends.

“This automatic saving is in addition to the host of benefits we offer to customers including inclusive EU Roaming and O2 Priority which offers exclusive rewards, unique experiences and daily perks, as well as Priority Tickets for thousands of gigs and events across the UK.”

Vodafone spokesperson said: “We encourage everyone to review their plan at the end of any contract so they can make sure they’re on the right deal for their needs – which often change over time. At the end of every contract period we notify our customers of the best value deals available, and can also support them in finding this online, over the phone and in stores.”

“We offer a wide range of great value packages and customers can save by bringing their mobile and broadband contracts to us – (up to £380 a year). Our loyalty programme Very Me gives customers a range of additional discounts on days out, discounts on takeaways, free coffees and more.”
