What must be disclosed before you sign, the five foreseeable reasons a bill rises, the five deliberate ways to bring one down, and what to do when nobody will fix it.
Written July 2026 · no prices published · nothing for sale
Since January 2025 any mid-contract increase has to be stated in actual money before you sign, rather than tied to a formula nobody can calculate in a shop.
| Reason | What was behind it |
|---|---|
| Mid-term increase | Disclosed in cash terms at the point of sale |
| Discount ending | Its length was stated when you bought |
| Past your allowance | Only possible where no spend cap was set; roaming is the usual source |
| Term ended | Not really a rise — a fall that never happened |
| Add-on renewed | One-off purchases sometimes repeat automatically |
| Move | Effect |
|---|---|
| SIM-only when the term ends | Strips out the handset payment — usually the largest single saving |
| Cut the allowance | Where three months of usage shows the tier is oversized |
| One-off add-on instead of upgrading | Covers a heavy month without repricing the year |
| Settle device credit early | On a split contract, leaves only airtime |
| Leave | Exit cost itemised before you commit |
Telephone calls leave nothing behind. A written complaint creates a record and a reference number, and a reference is what somebody reviews later.
At eight weeks unresolved — or immediately on a final response — the case goes free to the Communications Ombudsman. Its decision binds the network and does not bind you.
Ring us and we will go through it with you. Nothing is offered for sale at any point.
We hold no arrangement with any network, take no commission and sell nothing at all. If your question is not answered here, telephone and ask.
