Most people give up on broadband complaints somewhere around the third phone call. That is a rational response to a frustrating process, and it is also exactly why the process stays frustrating.
There is a defined escalation path with a free, independent adjudicator at the end whose decisions bind your provider. It works. Most people never reach it because they do not know it exists or do not know how to trigger it.
First: money you may be owed automatically
Before complaining about anything, check whether compensation should already be arriving.
Under the industry’s automatic compensation scheme, participating providers pay set daily or per-incident amounts for three failures, without you having to ask:
- Total loss of service not fixed within two full working days
- A missed engineer appointment, or one cancelled at short notice
- A delayed start to a new service
It should appear as a credit on your bill, not as a payment you claim. Most large providers participate; not all do.
If one of those things happened and no credit appeared, that alone is a valid complaint, and a well-founded one.
The escalation path
Step 1 — Complain formally, in writing.
Not a phone call. Email or the provider’s online complaint form. Writing creates a record and, critically, starts a clock.
Include, briefly:
- What went wrong, with dates
- What you have already done about it
- What you want — a repair, a refund, compensation, release from contract
- The phrase “I would like to raise this as a formal complaint”
That last phrase matters more than it should. It moves the case out of general support and into the complaints process, which is separately tracked and reported.
Step 2 — Ask for a deadlock letter, or wait.
You can escalate to independent adjudication when either:
- the provider issues a final response (sometimes called a deadlock letter), or
- eight weeks pass without resolution
Ofcom has been reducing this waiting period, so it is worth checking the current threshold rather than assuming — but either way, a stated deadline exists and you are not obliged to wait indefinitely.
Asking directly — “please treat this as deadlocked and issue a final response so I can refer it to ADR” — often produces a resolution on its own, because a referral costs the provider a case fee regardless of who wins.
Step 3 — Go to ADR. It is free.
Every UK provider must belong to one of two approved alternative dispute resolution schemes:
- CISAS
- The Communications Ombudsman
Your provider’s website will say which. It costs you nothing, it is independent, and the decision binds the provider — if the adjudicator says pay, they pay. You are not bound by it; you can reject the outcome and pursue other routes.
What makes a complaint succeed
Dates. A log of what happened when, even a rough one, is worth more than accurate recollection. Note the date and time of every call and the name of who you spoke to.
Specificity. “The internet keeps dropping” is weak. “The connection dropped for at least 15 minutes on 14 separate occasions between 3 and 20 August, logged in the router’s event page” is strong.
Evidence of the actual problem. Speed tests run over a cable, not Wi-Fi, at different times of day. This is important: providers are responsible for the line, not your Wi-Fi, and a complaint backed by Wi-Fi speed tests is easy to dismiss and frequently should be.
A stated remedy. Say what you want. Adjudicators respond to a clear ask.
Proportion. Asking for a refund of everything you have ever paid weakens an otherwise good case.
The specific grounds that tend to work
Persistent speeds below the guaranteed minimum. Providers give a minimum guaranteed speed at sale, and under the industry codes of practice, if they cannot fix a line that stays below it, you can usually exit penalty-free. Cabled evidence is essential.
Repeated total loss of service. Automatic compensation covers the outages; a pattern of them supports release from contract.
A price rise you were not told about. New consumer contracts must state any in-contract increase in pounds and pence upfront. An increase you were not told about is a contract change to your detriment, which carries a right to exit.
Being sold something that was not available. Charged for a service that was never delivered, or sold a speed the line cannot carry.
Billing after cancellation. Common, and usually resolved quickly once formally complained about.
What is not going to work
Wi-Fi coverage in your house. Your provider is responsible for delivering service to the property, not to the far bedroom through three stone walls. Test with a cable first.
Speeds below the advertised headline. Advertised speeds are averages achieved by a proportion of customers at peak time, not a promise to you. The number that binds is the minimum guaranteed speed you were given.
Wanting out of a contract because it got cheaper for new customers. Irritating, not a breach.
Congestion at 8pm on a contended service, if it still meets the guaranteed minimum.
If it is about a company that has gone bust
Different route entirely. ADR schemes cannot adjudicate against a company in liquidation.
Your protections there are the Direct Debit Guarantee for payments taken, Section 75 for credit card purchases over £100, and chargeback for debit cards. Our guide on what happens when a provider fails covers the sequence.
The realistic summary
Most complaints are resolved at step one if you put it in writing and use the word “formal”. Most of the rest resolve when you mention ADR, because the referral fee makes settling cheaper than fighting.
The adjudicator exists for the small number that get that far — and knowing it exists is most of the leverage.
