Mid-contract broadband and mobile price rises: what you can do
Providers can raise prices partway through a deal, but new Ofcom rules mean any increase must now be spelled out in pounds and pence before you sign.
Few things sting quite like a broadband or mobile bill creeping up while you are still tied into a contract you thought was fixed. Mid-contract price rises are common across UK providers, and for years many were pegged to inflation in a way that left customers unable to predict what they would actually pay. The rules have tightened, so here is how it works now and what your options are.
How mid-contract rises work
Many broadband, mobile and pay-TV contracts contain a clause allowing the provider to increase prices during the term. In the past these rises were often linked to an inflation measure such as CPI or RPI, plus an additional few percentage points, which made the final figure impossible to know when you signed up.
Ofcom, the communications regulator, has moved to stop this. Providers must now set out any in-contract price rise as a clear pounds-and-pence amount at the point of sale, so you can see the exact increase before you commit rather than a formula tied to a future inflation figure. This does not ban rises, but it does make them transparent and comparable between deals.
When you can leave without penalty
If your provider changes the terms of your contract in a way that is to your detriment, you generally have the right to exit without paying an early termination charge. The key is notice. Providers are required to tell you about certain changes in advance and give you a window to leave.
Crucially, a price rise that was clearly disclosed and agreed when you signed up may not trigger this right, because it was part of the deal from the start. That is exactly why the new pounds-and-pence disclosure matters: a rise you knowingly accepted is different from a change imposed on you. If you are unsure whether a specific increase gives you the right to leave, Citizens Advice publishes guidance on contract changes and cancellation rights.
Practical steps to cut the bill
Whether or not you can walk away, there are levers worth pulling. Diarise your contract end date, because the biggest savings almost always come from switching or renegotiating once you are out of the minimum term and no longer tied in. When a rise lands, call the retentions team and ask directly what they can do; providers frequently offer a discount to keep you rather than lose you to a competitor. If you are on a low income or receiving certain benefits, ask about social tariffs, cheaper broadband and mobile packages that several providers offer and that Ofcom actively encourages people to check.
The practical takeaway: read the price-rise line before you sign, note your exit date, and treat any increase as a prompt to haggle or switch. Transparency is now on your side, but only if you use it.
