A phone or broadband deal is a contract: the price, minimum term, service description and any future price changes should be clear before you commit.
Telecom contracts sit at the intersection of ordinary contract law, consumer law and Ofcom’s sector rules. The provider should give important contract information clearly, including the service, charges, contract length, termination conditions and any in-contract price rises that apply.
Since January 2025, new contracts cannot use inflation-linked or percentage-based in-contract price-rise terms. If a price rise is built into a new contract, it must be stated upfront in pounds and pence and the timing must be clear.
Key points
- Keep the contract summary and confirmation issued when you joined or recontracted.
- Separate fixed monthly charges, add-ons, device finance and usage charges.
- Check whether an early termination charge is actually permitted by the contract and sector rules.
- If the provider later changes a term beyond what you agreed, cancellation rights may arise.
What to preserve from the point of sale
- Contract summary and key information
- Order confirmation
- Price and any scheduled price rises
- Minimum term and end date
- Promotional discounts and when they end
- Speed/service commitments for broadband
- Device or handset agreement if separate
What was said during the sale can matter
If the contract was sold by phone or in store, promises made by the adviser can be important, especially where they induced you to sign. Note the date, channel and exact representation and request call recordings or sales notes if later disputed.
Recontracting creates a new evidence point
When you accept a new minimum term, preserve that version of the terms. Do not let a provider rely on an older or later tariff document without showing that it was the version incorporated into your agreement.
In practice
- Save the contract summary as a PDF at the time of purchase.
- Build a table separating service, add-ons and device finance if the monthly bill combines them.
- If the provider says a charge was “in the terms”, ask for the exact term and version that applied when you agreed.
What to do
A practical next-step plan
- Find your contract summary, confirmation and latest bill.
- Identify the minimum term, monthly price and any promised changes.
- List any term or charge you dispute.
- Ask the provider to identify the contractual basis.
- Make a formal complaint if the evidence does not match its position.
- Use telecom ADR after deadlock or six weeks where eligible.
Common traps
Things that often confuse the issue
- Do not assume the “package price” includes handset finance unless the documents say so.
- A discount ending at an agreed date is different from an unagreed price increase.
- Old inflation-linked terms can still affect some pre-January-2025 contracts; check when you agreed the contract.
Evidence worth keeping
When the provider cannot produce the agreement it relies upon.
Useful wording.
“Please provide the contract summary, order confirmation and the version of the terms/tariff that you say governed this agreement at the point of sale. Identify the clause relied upon for [charge/change/termination]. A current generic tariff page does not establish what I agreed on [date].”
If the dispute is unresolved, frame the complaint around the specific contractual proposition the provider has failed to evidence and escalate through ADR where eligible.
Contract changes have their own rules.
Where a provider changes contractual conditions, determine whether the change was already specifically agreed, is exclusively beneficial, purely administrative with no negative effect, directly imposed by law, or is a change that gives a penalty-free exit right. For new contracts from 17 January 2025, built-in price rises must be stated upfront in pounds and pence rather than as an inflation-linked or percentage formula.
Device finance may be a separate legal agreement.
A mobile service plan and a handset/device credit agreement can have different parties, payment terms, cancellation consequences and regulatory regimes. Cancelling the airtime service does not necessarily cancel the finance. Conversely, a dispute about a regulated credit agreement should not be answered solely by referring to telecom service terms.
Keep agreement numbers and payment schedules separate in your chronology.
Build the contract from the documents the provider was required to give you.
Modern telecom contracts are not just a line in an account screen. Preserve the pre-contract information, contract summary, order confirmation, terms, tariff, minimum-term date and any separate device-finance agreement. Those documents help answer what the service was, what it cost, how long you committed for and what changes were permitted.
If the provider says “this is in your terms”, ask it to identify the version and clause that formed part of your agreement rather than linking only to today’s generic website terms.
Point-of-sale evidence
The contract is more than the terms page the provider links to later
For regulated telecom services, Ofcom's contract rules require important information to be given before the customer is bound, including a contract summary and contract information. Preserve those documents, the order confirmation, screenshots of the checkout, the sales call or transcript if available, and any document presented for electronic signature.
If the provider later relies on a term that was not in the material supplied at the point of sale, ask when and how that term was brought to your attention. A link produced months later does not by itself prove what was presented before the agreement was made.
If the provider cannot produce the transaction-specific record
Separate the existence of standard terms from proof of the individual transaction. A generic current tariff page may show what the provider usually sells; it does not necessarily prove which version you saw, which options were selected, what price was agreed, or what document was signed.
Ask for the order audit trail, contract summary, contract information, confirmation email, electronic-signature metadata, relevant call recording and version of the terms in force at the time. Where the provider says an agreement was never formed but its systems generated an order confirmation, accepted an upfront payment or recorded a signature event, those records need to be reconciled rather than ignored.
Mobile purchases may involve more than one agreement
A handset purchase can involve an airtime/service contract and a separate device-finance or credit agreement. Do not assume that because both appeared in one checkout they have identical legal status, cancellation rules, complaint routes or regulators. Read the heading of each document and identify the legal entity providing each element.
If the device element is regulated credit, the Financial Conduct Authority/FOS framework may become relevant to that part of the dispute, while the communications service can remain within Ofcom/telecom ADR territory. Jurisdiction turns on the actual agreement and complaint, not the branding on the website.
Promises made before the contract can matter
Consumer Rights Act 2015 section 50 can make certain information said or written by a trader about the service binding where the consumer takes it into account when deciding to enter the contract or making a later decision about it. That does not mean every casual statement becomes a contractual guarantee, but it is a strong reason to preserve specific sales representations.
Examples include a quoted monthly price, eligibility statement, included feature, installation date or assurance that a particular service will work. Record the precise representation and how it affected the transaction.
The one-page contract summary is a starting point, not the whole contract
For residential and qualifying small-business customers, Ofcom requires key pre-contract information and a contract summary before consent. Keep both the short summary and the detailed contract information. The summary helps identify headline price, term, speed and termination information; the detailed terms answer more complex disputes.
What an adviser said can matter even if it is not printed in the standard terms
Under section 50 of the Consumer Rights Act 2015, information said or written about the trader or service can become binding where the consumer took it into account when entering the service contract or making a later decision, subject to the statutory qualifications. Preserve the sales recording, chat or contemporaneous note where a specific representation influenced the purchase.
