How to leave a business phone contract without paying a fee

First, get your paperwork straight

Before choosing a route, establish three facts: when your minimum term ends (your provider’s end-of-contract notification must tell you — if you never received one, that itself is a breach of the rules), what notice period applies, and exactly which terms you signed — the contract, any order form, and the provider’s published terms as they stood at signup. Providers update their published terms over time; the version that binds you is the one you agreed to, so save dated copies of everything.

The mid-contract change exit, done properly

If your provider raises prices or changes terms mid-contract in a way that wasn’t clearly set out when you signed, Ofcom’s rules give any business the right to leave without early termination charges. The provider must give you at least a month’s notice of the change and tell you about your right to exit. When the notice arrives:

• Check whether the change was provided for in the contract you signed — in pounds and pence, for price rises on contracts taken from 17 January 2025.
• Reply in writing within the exit window stated in the notice, saying you are exercising your right to terminate without penalty because of the change.
• Keep the provider’s notice and your reply — they are the whole case.

The end-of-term exit, without getting re-locked

Past your minimum term, every business can leave on one month’s notice paying only for service used. Two traps to avoid: don’t miss the end-of-contract notification (diarise your term end independently of it), and — if your business has 10 or fewer people — know that a provider cannot roll you into a fresh minimum term without your express consent. If that’s happened to you, challenge the renewal in writing and ask them to evidence your consent.

The service-failure route: evidence first

A contract can be ended for a sufficiently serious breach, and phone service that persistently fails may qualify — but this is the route where businesses most need their own solicitor, because getting it wrong can put you in breach instead. What makes it work is the record:

• Dated fault logs — every dropped call, outage and degraded period, with times and impact.
• Every support ticket and its outcome, kept with reference numbers.
• Complaints in writing, and the provider’s responses — showing the failures were raised and not fixed.
• A clear line from the failures to business harm: missed calls, lost orders, staff time.

Do things in this order

Whichever route fits, the sequence protects you:

• Gather the evidence and confirm your route before telling your provider anything.
• Port your phone numbers first — you have the legal right to take them, free, at any business size. Order the new service, port the numbers while the old service is live, and only then terminate. Numbers generally stay portable for at least a month after termination, but treat that as a safety net, not the plan.
• Give notice in writing, state the ground you’re relying on, and keep proof of sending.
• If a final bill arrives with an early termination charge you don’t owe, dispute it in writing rather than paying quietly — and if you’re a business of 10 or fewer, the ombudsman route can rule on it free.
