If you call a UK starting 01 or 02 from your mobile, the cost depends very much on your mobile plan i.e. whether you have inclusive landline minutes, are on a Pay As You Go tariff or have used up your allowance.
Below is a summary of what to expect in 2025.
Mobile-to-Landline: What affects the cost?
When you dial an 01 or 02 number from a mobile, 2 main factors determine what you’ll pay:
1 Does your monthly plan include minutes to UK landlines? If so (and you haven’t exceeded your allowance) the call is often included at no extra charge.
2. Are you outside your allowance or using PAYG without bundles? In that case, providers switch to per-minute charges, which typically range from around 3p up to 55p per minute, depending on operator & tariff.
As networks adjust pricing regularly, the only guaranteed way to know your specific cost is to check your personal plan or price guide.
Typical Mobile Call Costs to 01 Numbers
| Situation / Plan | Connection Fee | Per-Minute Rate | Notes |
| Inclusive-minutes mobile plan | n/a | FREE | Provided the call remains within allowance. |
| PAYG or out of bundle | none / standard | 3p–55p | Varies significantly between mobile networks. |
| Limited-call plan (allowance exceeded) | varies | provider’s out-of-bundle rate | Same rate used for all standard UK landlines. |
| Calling via home-phone landline | may apply | 10p–16p | Included for comparison only (not mobile rates). |
Why mobile-to-landline prices differ…
UK mobile operators treat 01 numbers as standard rate calls, but the price you pay still depends on your contract. Inclusive-minute bundles usually mean landline calls are free, but out-of-bundle charges can be much higher. The wide spread in pricing,from a few pence to well over 50p per minute, reflects how differently each provider handles fallback charges once user allowances are used up.
In Summary
In 2025, calling an 01 number from a mobile can cost anywhere from nothing (when covered by bundled minutes) to expensive (when charged out of allowance). As pricing varies so widely between networks and plans, neither callers nor businesses should assume a fixed rate. If you’re calling from a mobile, it’s wise to check your remaining allowance or provider’s cost guide.
