📌 Key Takeaways
- CISAS (Communications and Internet Services Adjudication Scheme) is an independent, free, Ofcom-approved Alternative Dispute Resolution (ADR) scheme operated by CEDR (Centre for Effective Dispute Resolution). It handles disputes between consumers and telecoms / broadband / mobile / landline / VoIP providers that could not be resolved internally. Its legal basis is Communications Act 2003 s.52 + Ofcom General Condition C4 (complaints handling and dispute resolution) + Alternative Dispute Resolution for Consumer Disputes (Competent Authorities and Information) Regulations 2015.
- You must first make an internal complaint: complain to your provider first. From 8 April 2026, Ofcom reduced the waiting period before you can apply for ADR from 8 weeks to 6 weeks (this applies only to complaints first raised on or after 8 April 2026; complaints raised before that date still use the 8-week period). Or apply immediately upon receiving a deadlock letter from your provider — no need to wait.
- 12-month longstop deadline: you must submit your CISAS application within 12 months of the date the provider issues the deadlock notice (extendable by mutual agreement). Miss this deadline and you may lose eligibility.
- Compensation cap of £10,000 (including VAT) — covering cash compensation, refunds, account credits and fee waivers combined. The “inconvenience and distress” element is typically no more than £100–£200. CISAS is completely free to consumers (as required by the Communications Act 2003).
- Decisions are “one-way binding”: a decision binds the provider only after the consumer accepts it; the provider must then comply within 20 working days. The consumer may reject the decision and pursue the matter through the courts or another forum instead. The provider cannot reject or appeal.
- Three Ofcom-approved ADR schemes: currently approved schemes include Communications Ombudsman (formerly Ombudsman Services: Communications), CEDR (operating CISAS) and Consumer Dispute Resolution Ltd. Which scheme you should use depends on which scheme your provider has joined — check first, and apply to the right one.
- Jurisdiction: telecoms regulation is a UK-wide reserved matter — CISAS covers England, Scotland, Wales and Northern Ireland, unlike the Legal Ombudsman which is limited to England and Wales only.
Many UK Chinese residents have encountered telecoms disputes: broadband installed for two months but still not working, unexplained overcharging, a contract quoted at £25 that jumped to £45, switching blocked, astronomical early termination charges (ETCs), continued debt chasing after cancellation, or hundreds of pounds docked for overseas roaming. Customer service keeps passing you around, emails go unanswered — so how do you formally hold them to account and obtain compensation?
The answer is ADR (Alternative Dispute Resolution). UK law requires every consumer-facing telecoms and broadband provider to join an Ofcom-approved ADR scheme, allowing consumers, after exhausting the internal complaints process, to refer their dispute to an independent, free, enforceable adjudication body. CISAS is one of the two principal schemes.
This guide sets out: the legal basis for CISAS, how it differs from other ADR schemes, eligibility requirements, the 6-week rule and deadlock letter, the 12-month time limit, the application process, types and limits of remedies, the binding effect of decisions, what is excluded from scope, scenarios common in the Chinese community, and the relationship between CISAS, Ofcom and the Small Claims Track. All cited legislation links to legislation.gov.uk / Ofcom / CEDR.
Primary legal and regulatory basis:
- Communications Act 2003 s.52 (Ofcom’s statutory power to set General Conditions — including complaints handling and dispute resolution)
- Ofcom General Conditions of Entitlement — Condition C4 (complaints handling and dispute resolution; requires providers to join an approved ADR scheme)
- Alternative Dispute Resolution for Consumer Disputes (Competent Authorities and Information) Regulations 2015 (certification framework for ADR schemes)
- Consumer Rights Act 2015 s.49 (services must be provided with “reasonable care and skill” — the substantive legal basis for CISAS determinations on service quality)
- Consumer Rights Act 2015 Part 1 Chapter 4 (consumer remedies for service contracts)
- CISAS Scheme Rules (CEDR current version, including April 2026 rule update) — cedr.com/consumer/cisas
- Ofcom — Alternative Dispute Resolution scheme guidance — ofcom.org.uk ADR
1. What Is ADR? The Legal Basis for CISAS
UK protection for telecoms consumers rests on Ofcom regulation + mandatory ADR:
Under Communications Act 2003 s.52, Ofcom has the power to set General Conditions of Entitlement, of which Condition C4 requires every provider serving Domestic and Small Business Customers to:
- Maintain a transparent, effective internal complaints handling procedure;
- Join an Ofcom-approved independent ADR scheme; and
- Issue an ADR referral letter/notification to the customer when the internal complaint reaches deadlock or the statutory waiting period has elapsed, informing them of their right to escalate.
| Party | Role | Legal / rules basis |
| Ofcom | Telecoms regulator — sets General Conditions, approves ADR schemes, handles systemic breaches (but does not handle individual compensation claims) | Communications Act 2003 s.51–52 |
| ADR scheme (CISAS etc.) | Independently adjudicates individual consumer disputes and can award compensation | GC C4 + ADR Regulations 2015 |
| CEDR | Independent dispute resolution body that operates CISAS (CEDR Services Ltd, London) | CISAS Scheme Rules |
| Adjudicator | Independent, typically legally qualified decision-maker — issues a reasoned written decision | CISAS Scheme Rules |
📌 Ofcom will not recover compensation for you: many people assume that “complaining to Ofcom” will get their money back. Ofcom looks only at systemic, industry-wide issues (such as a provider’s widespread non-compliance) and does not resolve individual compensation claims. To recover money, obtain a refund, or get a contract cancelled — use ADR (CISAS).
2. CISAS, Communications Ombudsman or CDR? — Check Which Scheme Your Provider Uses
There are several Ofcom-approved telecoms ADR schemes in the UK. A provider belongs to only one, and you must apply to the correct one:
| ADR Scheme | Operated by | Notes |
| CISAS | CEDR (Centre for Effective Dispute Resolution) | The subject of this guide. Uses an “adjudication” model |
| Communications Ombudsman | Ombudsman Services (formerly Ombudsman Services: Communications) | Uses an “ombudsman” model; broadly similar in effect |
| Consumer Dispute Resolution Ltd (CDR) | CDRL | A more recently approved scheme |
How to check which scheme your provider uses:
- Check your provider’s contract terms, bills or “Complaints” page on their website — under GC C4 they must state the name of their ADR scheme;
- Or check Ofcom’s ADR information page (ofcom.org.uk ADR);
- Or ask customer services directly: “Which ADR scheme are you a member of?“
⚠️ Applying to the wrong scheme means rejection: CISAS can only adjudicate disputes with providers that are members of CISAS. If your provider belongs to the Communications Ombudsman, CISAS will refuse the application. Check first, then apply.
3. Who Is Eligible to Apply
CISAS accepts disputes from the following customers of CISAS member providers:
| Eligibility category | Description |
| Residential / domestic customer | An individual or household using telecoms or broadband services — the vast majority of UK Chinese users fall into this category |
| Small business customer | As defined by Ofcom’s General Conditions, broadly businesses with no more than 10 employees — small restaurants, takeaways, small trading companies, etc. |
| Not-for-profit organisation | Qualifying small associations, charities, etc. |
📌 Nationality and residence do not affect eligibility: as with the Legal Ombudsman, your eligibility is not affected by whether you are a UK citizen or have settled status. You simply need to be a UK customer of a CISAS member provider. Language is no barrier — a family member, friend or Circle Vision Foundation can help you complete the form.
4. Prerequisites: Internal Complaint First + the 6-Week Rule / Deadlock Letter
CISAS is a last resort — you cannot bypass the provider and apply directly. You need to satisfy one of two trigger conditions:
1. The statutory waiting period has elapsed (6 weeks from April 2026)
| Date complaint was raised | Waiting period before ADR application |
| Complaints raised on or after 8 April 2026 | 6 weeks (Ofcom rule change effective 8 April 2026) |
| Complaints raised before 8 April 2026 | 8 weeks (previous rule) |
📌 Major change on 8 April 2026: Ofcom reduced the waiting period before a consumer can escalate to ADR from 8 weeks to 6 weeks, giving consumers who are being stalled faster access to independent adjudication. This change applies only to complaints first expressed to the provider on or after 8 April 2026.
2. You receive a deadlock letter — you can apply immediately
If the provider has made clear before the waiting period ends that it cannot or will not resolve the complaint further, it will (or should, on your request) issue a deadlock letter. The conditions for deadlock are:
- The provider has notified you of its findings / proposed resolution of the complaint;
- You have told the provider that the proposed resolution does not satisfy you; and
- The provider does not intend to take any further steps.
On receipt of a deadlock letter, you do not need to wait 6 weeks — you can apply to CISAS immediately.
⚠️ Always complain in writing and keep records: make internal complaints by email or in writing wherever possible (not just by phone) and retain records of the date of complaint, its content and the provider’s response. The waiting period runs from the date you first expressed dissatisfaction — that date is crucial.
5. The 12-Month Longstop Deadline — Do Not Miss It
| Time limit | Rule |
| Longstop for applying to CISAS | Application must be submitted within 12 months of the date the provider issues the deadlock notice |
| Extension | Can be extended only by mutual agreement of both parties |
📌 Practical advice: once 6 weeks have passed (or you have received a deadlock letter), apply promptly — do not wait until you are close to the 12-month limit. The fresher and more complete your evidence (bills, contract, chat logs, customer service call records), the stronger your case.
6. Application Process and Evidence Required
| Step | Details |
| 1. Internal complaint | Complain to your provider in writing; retain evidence; wait 6 weeks or obtain a deadlock letter |
| 2. Online application | Submit via the CISAS online portal (or by email to [email protected] / phone for assistance) |
| 3. Set out your claim | State clearly: what happened, and what remedy you are seeking (refund / cancellation / specific compensation amount) |
| 4. Provider’s response | CISAS notifies the provider; the provider submits a “defence” with supporting evidence |
| 5. Adjudication | An independent adjudicator reviews both parties’ written submissions and issues a reasoned written decision |
| 6. Accept or reject | You decide within the specified period (typically around 30 working days) whether to accept or reject the decision |
Recommended evidence checklist:
- Service contract / package confirmation (contract price, package content, minimum contract term)
- All bills (with overcharged or incorrectly charged items highlighted)
- Internal complaint emails and the provider’s responses, plus any deadlock letter
- Dates and summaries of customer service calls (call recordings or reference numbers are ideal)
- Proof of loss (for example, the cost difference of switching to another network, lost earnings, additional expenses)
- Your specific remedy (amount, cancellation, removal of debt collection record, etc.)
📌 CISAS is a “paper-based adjudication”: there is usually no attendance required, no hearing — the entire process is written and online, which is particularly convenient for Chinese speakers who are less confident in spoken English. Setting out the facts and evidence clearly, with a timeline, is the key.
7. Compensation and Remedies — Cap of £10,000
| Type of remedy | Description |
| Compensation | Monetary compensation for actual loss and inconvenience |
| Refund | Return of amounts overcharged, incorrectly charged, or charged for services not provided |
| Account credit | A credit applied to your account |
| Fee waiver | Cancellation of a charge — typically used to set aside an unjustified early termination charge |
| Written apology | A formal written apology from the provider |
| Corrective action | For example: restoring service, correcting billing, removing an erroneous credit record or debt collection entry |
Key figures:
- Total cap of £10,000 (including VAT) — the combined total of all the above cannot exceed this amount;
- “Inconvenience and distress” element — adjudicators typically award no more than £100–£200;
- CISAS is completely free to consumers (as required by the Communications Act 2003).
📌 Is £10,000 enough? For the vast majority of residential and small-business telecoms disputes (billing, termination charges, service disruption losses), this is more than sufficient. If your losses far exceed £10,000 (rare — for example, significant commercial losses), the CISAS cap may be inadequate and you should consider the Small Claims Track or the County Court (see section 11).
8. The Binding Effect of a Decision — “One-Way” Binding
A CISAS decision has a different legal effect from a court judgment. It is one-way:
| Scenario | Legal effect |
| Consumer accepts the decision | Decision binds the provider; provider must comply within 20 working days (payment / refund / cancellation / correction etc.) |
| Consumer rejects the decision | Decision is not binding on either party; consumer may take the matter to the courts or another forum |
| Provider’s position | Provider cannot reject or appeal — if the consumer accepts, the provider must comply |
📌 Think carefully before accepting: once you accept a decision, it is treated as a final settlement of that dispute with the provider — which generally means you waive any further claim on the same matter. If the award is far below your actual loss and you are confident a court would award more, consider rejecting it and pursuing the Small Claims Track instead (though you will then bear the burden of proof and the time cost).
9. What CISAS Does Not Cover — Applying to the Wrong Scheme Means Rejection
CISAS has clear exclusions. The following matters are outside CISAS jurisdiction and should be directed to the appropriate body:
| Matter not covered | Where to go instead |
| Data protection / privacy breach | ICO (Information Commissioner’s Office) — ico.org.uk |
| Personal injury | Court / personal injury solicitor |
| Property damage (e.g. installation works damaging your home) | Court / insurance |
| Discrimination (under the Equality Act 2010) | Court |
| Employment disputes | ACAS / Employment Tribunal |
| Disputes about telegraph poles / in-home wiring / network content | Follow the relevant alternative process depending on the issue |
| Pure commercial decisions (e.g. the provider’s pricing policy itself) | Not a service quality complaint |
| Fraud / criminal conduct | Action Fraud / police |
📌 Parallel proceedings are possible: for example, a provider cutting off your service causing loss (CISAS) + disclosing your personal data (ICO) — you can pursue both simultaneously; they do not affect one another.
10. Common Scenarios in the Chinese Community
| Scenario | Remedies CISAS can award (examples) |
| Broadband not working / frequent disconnections | Refund for the period without service + inconvenience compensation + cancellation without early termination charge if appropriate |
| Billing errors / price increase without notice | Refund of overcharged amounts + corrected bills + account credit |
| Early termination charge imposed unjustifiably | If the charge was not properly disclosed or is otherwise unjustified, an adjudicator can order a waiver |
| Switching / number porting failure | Compensation for losses caused by the failed switch + correction |
| Continued debt chasing / credit record impact after cancellation | Removal of erroneous debt entry + correction of credit record + compensation |
| Unexpectedly large overseas roaming bill | Where the provider failed to warn you or to apply a spending cap as required, an adjudicator can order a refund |
| Contract auto-renewed / price increased at end of term | Refund of unjustified charges + cancellation |
📌 Language is not a barrier: telecoms contracts and bills are often full of jargon, and many Chinese residents suffer financially because they cannot understand them. Circle Vision Foundation can help you understand your contract, calculate the amount you have been overcharged, and set out your claim in English.
11. CISAS vs Ofcom vs Small Claims Court
| Route | What it handles | Cost | Can you get compensation? |
| CISAS (ADR) | Individual disputes between consumer and provider | Free | Yes, up to £10,000 |
| Ofcom | Systemic / industry-wide breaches | Free | Does not handle individual compensation |
| Small Claims Track | Contract / tort money claims | Court fee payable | Yes (potentially higher amounts, but you must prove your case yourself and it may take longer) |
📌 Recommended order: first internal complaint → wait 6 weeks / obtain deadlock letter → CISAS (free, written, enforceable). CISAS is usually the most cost-effective route. Only consider the Small Claims Track when your losses far exceed £10,000, or when you have rejected a CISAS decision.
