Preface

Since the previous refund and rights-protection guide was published, a number of readers have reported the same outcome: after going through the formal complaints process, they received a firmly worded Final Response that —

• cites Clause 5.3, asserting that “once credit is applied to your account, we have no obligation to refund it”;
• cites Clause 3.5(k) and the Fair Usage Policy to conclude the account no longer qualifies for the service;
• explicitly refuses to reinstate the service, and explicitly refuses to refund anything.

Most readers’ first reaction after reading such a letter is: is it game over?

This article answers three questions:

1. Why is giffgaff so confident taking this hardline stance?
2. Does that hardline stance actually hold up legally?
3. Once we reach the Communications Ombudsman arbitration stage, what exactly is our legal basis?

Here is the conclusion up front: the disconnection is defensible, but withholding the money is not. giffgaff does have a reasonably strong contractual basis for “disconnection”, but this letter deliberately conflates “the right to disconnect” with “the right to withhold the balance”. The strongest legal weapon at the arbitration stage isn’t Clause 4.11, as many assume — it’s Ofcom General Condition C7.7(d).

The analysis below is based on public, verifiable primary sources as of 4 August 2026.

Part One: Untangling Two Deliberately Conflated Issues

The entire argumentative structure of the Final Response runs like this: because you breached the Fair Usage Policy, we disconnected you, and therefore we won’t refund your balance.

The first step of that reasoning holds up. The second does not. These are two legally distinct questions:

So the first principle of your arbitration strategy is: don’t fight a battle you can’t win (reinstatement); put everything into the battle you’re likely to win (recovering the balance).

Part Two: Where giffgaff’s Confidence Comes From

To rebut an opponent, you first have to understand them. giffgaff’s hardline stance isn’t pure bluster — it does hold a few real cards.

1. The surface-level threat of Clause 5.3

Once credit is applied to your Account, we have no obligation to refund it to you in the absence of any legal or regulatory entitlement.

Read in isolation, the first half sounds like “no refunds, period”. But note the proviso in bold: in the absence of any legal or regulatory entitlement.

This is not an unconditional forfeiture clause. As soon as you can point to any legal or regulatory entitlement to a refund, Clause 5.3 lets the money go by its own terms. The Final Response cites this clause while saying nothing whatsoever about the proviso — that’s its first crack.

2. The disconnection power under the Fair Usage Policy is real

Clauses 2.13 and 3.5(k), together with the FUP, allow giffgaff to impose extra charges, throttle speeds, suspend, or even disconnect a SIM once it deems usage to be in breach — and the FUP explicitly states that its list of breaches is non-exhaustive. This is not a fight you can win, and not one worth picking.

3. Its real policy basis: the help page’s “no refund for non-permitted usage”

The most specific documented basis for giffgaff refusing refunds doesn’t actually sit in the Terms — it sits on its official deactivation explainer page:

You can get a refund for your remaining credit by contacting an agent within 30 days of deactivation.

• After 30 days, unused credit expires and cannot be recovered, as per our terms and conditions.
• Refunds are not available if your account was deactivated due to non-permitted usage.

This explains why the Final Response is worded the way it is: the support team is executing this internal policy — no refund for accounts disconnected for a policy breach.

But note two things:

• This is wording on a help page, not a contract clause. The current Clause 4.11, which sets out refund eligibility, contains no “except where disconnected for a breach” carve-out;
• The same page also confirms something else: you can request a refund within 30 days of disconnection — meaning giffgaff itself accepts that “disconnection” and “refund” can coexist. The dispute is only over whether the unilateral “non-permitted usage” exclusion it has carved out is lawful.

This 30-day window also matters enormously for everyone affected: make sure you apply for your PAC and submit your refund request within 30 days of disconnection — don’t delay.

4. The sequencing defence

The strongest card giffgaff is legally likely to play is: the account was already terminated for your breach, and the PAC issued afterwards was merely to “preserve the number” rather than part of a normal switching process — meaning the switching-refund rules were never triggered.

This is exactly why, in your arbitration bundle, evidence of a completed port is far more valuable than evidence of merely having received a PAC. Requesting a PAC without completing the transfer hands your opponent its easiest possible defence.

5. Evidence asymmetry

The balance at the time of disconnection, the source of the top-ups, usage history, and the exact time of disconnection are all held entirely by giffgaff. Users who haven’t taken screenshots and kept top-up receipts in advance can easily get dragged into a war of attrition over “you can’t prove the amount”.

6. Betting on attrition

(The following is inference.) These disputes are typically worth only tens of pounds. giffgaff most likely expects that the vast majority of affected users won’t complete a switch, won’t identify the relevant Ofcom rules, won’t survive the six-week complaints window, and certainly won’t formally file for arbitration. Yet once a case is accepted by the Ombudsman, giffgaff must pay a case fee of up to roughly £335 plus VAT — far more than most of these balances are worth. A firmly worded Final Response is, in itself, a low-cost deterrent.

Part Three: 🔥 The Core Legal Basis for Arbitration — Ofcom C7.7(d)

This is the single most important section of the article. The previous guide relied mainly on Clause 4.11, but 4.11 is only a contractual promise, and giffgaff can dodge it with “eligible does not mean entitled”. What actually turns the refund from a “request” into an “obligation” is UK communications regulation.

1. The rule, verbatim

Ofcom’s current General Conditions (in force from 8 April 2026) require the Losing Provider under Condition C7.7(d) to:

refund, upon request, any remaining credit to the Switching Customer using prepaid services, minus any fees provided for in their contract with the Switching Customer, in so long as such fees are proportionate to the actual costs incurred by the Losing Provider in offering the refund.

In plain terms:

For a switching customer using prepaid services, the losing provider must refund any remaining credit on request; it may only deduct fees that are expressly set out in the contract and proportionate to the actual cost of providing the refund.

Sources:

• Ofcom General Conditions of Entitlement
• Ofcom’s formal notification of amendments (containing the C7.7(d) text)

Ofcom also requires, under C7.12(g)(iii), that providers proactively disclose the prepaid balance, the right to a refund, the process for requesting it, and any applicable conditions during the switching process. Look back at that Final Response: it explains in detail how to request a PAC, but doesn’t say a single word about your legal right to a refund of your balance — that alone is a disclosure failure worth raising in arbitration.

Separately, thinkbroadband’s investigative report on this issue also cites Ofcom General Condition C7.22(c), which requires a provider to set out any remaining credit balance on the account when it issues a customer with a PAC. This is a disclosure duty distinct from C7.7(d) itself (which imposes the refund duty), but it further confirms the regulatory framework’s position: in a switching scenario, a prepaid balance has never been an asset a provider is entitled to keep quiet about, or simply seize.

2. A three-layer closed loop of evidence

Stack these three documents together, and giffgaff’s refusal-to-refund position runs into an internal contradiction it cannot escape:

And the proviso in Clause 5.3 — “in the absence of any legal or regulatory entitlement” — is precisely filled in by C7.7(d):

Once a switch has been completed, C7.7(d) is exactly the “regulatory entitlement” that Clause 5.3 itself carves out.

At this point, if giffgaff wants to keep refusing a refund, it has to explain to an arbitrator why an Ofcom General Condition, its own contractual clause, and its own official help page would all simultaneously not apply. It has no documented basis capable of answering that question — all it has is an internal policy line on one help page, and a help page cannot override a General Condition.

3. A necessary clarification: “eligible” does not mean automatic

To be precise, the wording of 4.11 is “you will only be eligible for a refund” — meaning you become eligible to apply for one, not that a refund is issued automatically. An opponent can nitpick that wording.

This is exactly where C7.7(d) earns its value: its wording is must refund, upon request. So the correct order of argument in your submission is: first establish the statutory duty under C7.7(d), then use 4.11 and the help page to show that giffgaff’s own commitments are consistent with it.

4. Corroboration from independent media and an official statement

The UK broadband/telecoms outlet thinkbroadband reported on this in August 2026, and put the issue directly to giffgaff, receiving the following written response:

We have identified a proportion of PAYG SIMs associated with extended or permanent use outside the UK. This is in breach of our T&Cs and a misuse of our service… the related SIMs have been disconnected.

— giffgaff spokesperson

This confirms two things. First, this is a company-level, batch policy action, not the discretion of an individual support agent — arbitration materials can cite this to argue that the Final Response reflects a corporate position, not an isolated misjudgement. Second, giffgaff’s statement to the press says nothing at all about the balance issue — it uses the same “talk only about disconnection, say nothing about refunds” script both in public and in its Final Response letters to affected users.

Even more notable: the same outlet, working from the same primary sources (Clauses 4.11/5.3, Ofcom’s General Conditions, the official refund help page), reached an independent conclusion that is entirely consistent with this article’s:

The disconnections, in short, look defensible. What happens to the money afterwards, is another story.

That sentence is, in effect, the English original of this article’s headline conclusion — “disconnection is justified, withholding the money is not” — arrived at independently by a third-party outlet with no connection to this author, which serves as useful corroboration that this argument is not a lone voice.

Part Four: Dissecting the Legal Gaps in the Final Response, Clause by Clause

Gap One: Clause 5.3 is quoted out of context

As covered above, 5.3 comes with a built-in proviso. Citing it to avoid a refund is the equivalent of citing a clause that says “no refund unless the law requires one” as proof that “no refund is required even when the law does require one.” The logic doesn’t hold.

Gap Two: the Fair Usage Policy’s list of remedies never includes “confiscating the balance”

Section 5 of the FUP lists the available remedies as: additional charges, investigation, throttling, suspension, disconnection, downgrading a plan, and blocking further plan purchases. Not one of these is “confiscating purchased prepaid credit”.

giffgaff is entitled to disconnect your SIM, but nothing in the Terms authorises turning that disconnection into a revenue event. Disconnection is an act of contract management; withholding the entire balance is an act of disposing of property — the former is authorised, the latter is not.

Gap Three: Clause 3.5(k) is merely a compliance obligation, and creates no power of forfeiture

3.5(k) requires the member to comply with the Terms and the FUP — it is an obligation clause. Breaching it can trigger the remedies set out in the FUP (disconnection, etc.), but nothing in that clause, from beginning to end, grants giffgaff any power to impose a financial penalty.

Gap Four: “primary UK residency” has no clear footing in the current mobile Terms

The Final Response states that “our terms regarding primary UK residency and usage are strictly enforced.” But the current mobile services Terms contain no clear, general “UK residency requirement”; the detailed periodic-travel rules sit in the “Roaming in the EU and selected destinations” section, while giffgaff’s own roaming page simultaneously and openly sells PAYG Rest of World roaming (usable until it runs out).

This isn’t recommended as your main line of attack in arbitration (the FUP’s non-exhaustive list gives giffgaff room to argue broadly), but it does illustrate that the strength of language in the Final Response outstrips the clarity of the underlying Terms.

Gap Five: the help page’s “non-permitted usage” exclusion doesn’t hold up on its own terms

Even if giffgaff relies on the help page’s exclusion as a last line of defence, it still has to clear four hurdles:

1. Regulation takes precedence: a help page cannot override a statutory duty imposed by an Ofcom General Condition;
2. Contractual text: when relied on as part of a consumer contract, it directly conflicts with the unqualified wording of 4.11, and under Section 69 of the Consumer Rights Act 2015, any ambiguity must be interpreted in the way most favourable to the consumer;
3. Fairness scrutiny: a rule that says “a breach means forfeiting the entire purchased balance” sits squarely in the crosshairs of unfair-term scrutiny — see the next section;
4. Doubtful timing: according to thinkbroadband’s investigation, the current version of this help page appears to have been updated recently, during this very wave of disconnections, and the reporter also noted they “couldn’t locate an archive copy of this page” — no historical archived version could be found. If this exclusion was only added after the mass disconnections began, its credibility as a “longstanding policy” collapses considerably. It’s worth submitting the results of a Wayback Machine (or similar archive tool) search as arbitration evidence — whether or not an archived copy turns up.

Part Five: The Second Line of Defence — Consumer Rights Act 2015

If giffgaff insists that “a breach entitles us to forfeit the entire balance,” UK consumer protection law becomes the next front:

• CRA 2015, Section 62: a term (including a consumer notice) that is contrary to the requirement of good faith and causes a significant imbalance in the parties’ rights and obligations to the detriment of the consumer is not binding on the consumer;
• Section 68: written terms must be transparent and expressed in plain, intelligible language;
• Section 69: where a term is capable of more than one meaning, the interpretation most favourable to the consumer prevails;
• Schedule 2, paragraphs 6–8 (the “grey list”): terms requiring a consumer to pay a disproportionately high sum in compensation for breach, or allowing a trader to retain sums paid for services not yet supplied when the trader itself terminates, are both listed as potentially unfair.

The CMA’s official guidance, CMA37 (July 2026 edition), is even more direct:

• Paragraph 6.63: sanctions for breach must not exceed what is necessary to achieve their purpose;
• Paragraph 6.74: even where a consumer is seriously in breach, a trader withholding prepayments should correspond to the loss directly caused by that breach — not an automatic full forfeiture regardless of whether the balance is £5 or £300.

There’s one question an arbitrator can’t avoid asking: what relationship does the balance you’ve withheld actually bear to the loss you claim to have suffered from this user’s roaming? giffgaff’s Final Response offers no answer at all — its roaming costs have already been settled through wholesale billing, and that is an entirely separate account from the unspent prepaid balance sitting in the customer’s account.

A note on positioning: this set of arguments is your second line of defence. Your primary argument is always C7.7(d), because a statutory obligation is the cleanest and hardest thing to rebut.

Part Six: ⚠️ Can This Final Response Go Straight to Arbitration?

It’s strong evidence of “an unambiguous refusal to refund”, but it may not, on its own, be a fully compliant ADR Letter.

Compare this against Ofcom’s C4 complaints rules: once a provider has communicated the outcome of its investigation, the consumer has made clear they are dissatisfied, and the provider does not intend to take any further step capable of producing a different outcome, it must immediately issue an ADR Letter, which must include referral information for the relevant ADR body.

But this Final Response, while explaining the decision and its reasoning in detail, makes no mention of the Communications Ombudsman, does not tell you that you have a right to escalate to arbitration, and provides no contact details for doing so.

So there are two scenarios:

• If your first formal complaint is already six weeks old: don’t wait for a supplementary letter — go straight to raising a dispute with the Communications Ombudsman;
• If it isn’t six weeks old yet: the safest course is to reply in writing immediately, rejecting the outcome and demanding a compliant ADR Letter (template in Part Eight), to avoid your submission being bounced back for failing the acceptance threshold.

Part Seven: Assessing the Odds

The Communications Ombudsman does not publish win rates for cases like this, and individual decisions do not bind future cases. The following is a conditional assessment based on the structure of the relevant rules — it is not a prediction of probability:

Overall assessment: completing a switch, being able to evidence the source of the balance, explicitly abandoning any claim for reinstatement, and leading with C7.7(d) as your primary argument together put a refund claim in the medium-high to high odds range (confidence: medium-high).

The biggest uncertainty is how far C7.7(d) applies in the “disconnected first, switched afterwards” scenario — no published decision on this specific point has been found. That’s exactly why speed matters: completing your PAC request and refund request within the 30-day window after disconnection minimises the room giffgaff has to run a defence.

Part Eight: The Playbook for the Arbitration Stage

1. The claim, in one sentence

Wrongful retention of purchased unused prepaid credit following a completed switch.

Don’t frame it as “giffgaff disconnected me unlawfully” — frame it as “giffgaff wrongly withheld my purchased balance after a completed switch.” The narrower the claim, the higher the odds.

2. Eight arguments, in this order

1. I am not disputing the decision to disconnect the service, and I am not asking for it to be reinstated;
2. I completed a switch to [new provider] via PAC on [date];
3. At the time of disconnection, the account held £[amount] of purchased and unused prepaid credit (evidence attached);
4. Ofcom C7.7(d) requires the losing provider to refund that balance on request, deducting only contractual fees proportionate to the actual cost of the refund;
5. C7.7(d) is precisely the regulatory entitlement preserved by the proviso in Clause 5.3;
6. Clause 4.11 and the official refund help page independently confirm the same refund position;
7. The FUP authorises disconnection, but no clause authorises forfeiting purchased credit;
8. If giffgaff claims the balance offsets a loss, ask it to state the contractual basis, how that loss was calculated, and why forfeiting the entire balance is proportionate.

3. Evidence checklist

• The disconnection notice email and the complete Final Response;
• The formal complaint and every piece of correspondence (with dates and case references);
• Screenshots of the balance before disconnection, top-up receipts, bank/card statements;
• A breakdown separating purchased credit from any gifted/referral bonus credit;
• Evidence the PAC was issued, and confirmation from the new provider that the port completed;
• Screenshots of Clauses 4.11 and 5.3, and of the official refund help page;
• A clear record of your refund request and giffgaff’s refusal.

If you can no longer log into the account, ask the Ombudsman in your submission to require giffgaff to disclose the closing balance, the source of those funds, top-up records, usage records, and complaint records — its Terms of Reference allow the Ombudsman to require a provider to disclose material.

4. Remedies to request

Ask only for enforceable, non-punitive items:

1. Refund of the verified purchased, unused credit;
2. Written confirmation of the balance and its composition at the time of disconnection;
3. A written explanation or apology for the complaint-handling failures;
4. Where the evidence supports it, a modest Time and Trouble Award (typically in the £50–100 range — see What to expect).

5. English-language template for replying to a Final Response (use if under six weeks)

Subject: Rejection of Final Response and request for a compliant ADR Letter

I do not accept the outcome in your Final Response. The complaint remains unresolved.

I am not challenging the disconnection and I am not requesting reinstatement. The unresolved issue is giffgaff’s refusal to refund £[amount] of purchased and unused prepaid credit following the transfer of my number to [provider] on [date].

Ofcom General Condition C7.7(d) requires the losing provider, upon request, to refund remaining credit to a switching customer using prepaid services, subject only to contractual fees proportionate to the actual cost of offering the refund. This is the regulatory entitlement expressly preserved by clause 5.3 of giffgaff’s Terms. Clause 4.11 and giffgaff’s current refund help page also confirm the right to request return of unused credit when moving a number to another network.

Please identify any contractual refund fee on which giffgaff relies, the actual cost said to justify that fee, and the contractual or regulatory provision said to permit forfeiture of the entire purchased balance following a Fair Usage Policy disconnection.

As I have rejected the proposed outcome and giffgaff states that it will not take further steps capable of producing a different outcome, please immediately issue a compliant ADR Letter under Ofcom General Condition C4, including the Communications Ombudsman referral information.

Closing thoughts

Back to the three questions we opened with.

Why is giffgaff so confident taking this hardline stance? Because it does have a genuine basis on the disconnection question, because it has a help page stating that non-permitted usage disqualifies you from a refund, and because it’s betting you won’t check the Ofcom rules — and won’t have the stamina to see the process through.

Does that hardline stance actually hold up? No. Clause 5.3 is quoted out of context; the FUP grants no power to confiscate a balance; its own Clause 4.11 and its own refund help page both contradict it; and Ofcom C7.7(d) turns “must refund a switching customer’s prepaid balance on request” into a statutory duty.

What is the legal basis for arbitration? In one line: complete the switch, then invoke Ofcom C7.7(d) to demand the return of the purchased, unused balance.

A final three-step action list:

1. Within 30 days: apply for a PAC, screenshot your balance, submit your refund request, and complete the switch as soon as possible;
2. After receiving a Final Response: reject the outcome in writing and demand a compliant ADR Letter (or confirm the six weeks have already elapsed);
3. File for arbitration: frame the claim around the balance only, and lead with C7.7(d) as your sole primary argument.

giffgaff is strong on disconnection and weak on withholding your money. Choose the right battlefield, and this letter stops being the end of the road — it becomes giffgaff’s own written evidence of a refusal to refund.
