Calling 0345 from BT – a closer look
Okay, the cost of calling a 0345 number from BT depends on your plan and if you’re within your inclusive minutes. However, as 0345s are part of the ‘03’ non-geographic number range, calls must be charged at the same rate as standard UK landlines i.e. 01/02 numbers.
So, if your BT package includes calls to landlines (as many do), 0345 calls should be covered. If you’re outside your allowance or on a pay-as-you-go/limited minutes tariff, then standard per-minute charges typically apply.
Typical Call Costs with BT
| Call scenario / BT plan | Approximate cost per minute for calling an 0345 number* |
| BT landline or mobile (within your inclusive minutes / plan) | Free (included with standard landline allowance) |
| BT landline (outside plan allowance / pay-as-you-go) | Approx. 29.6 p/min |
| BT mobile (outside plan allowance / pay-as-you-go) | Approx. 51.8 p/min |
Please note: These are typical costs. Actual charges may vary – check your BT tariff/latest ‘Call Packages & Charges’ guide for exact rates.
What this means for callers:
- If your BT plan includes ‘UK landline calls’, then 0345s are counted exactly like 01/02 regional numbers. So, calling them will likely be free or covered by your plan.
- If you’re on a pay-as-you-go or limited-minutes landline plan, charges will be around 29.6p per minute.
- If calling from a BT mobile outside your minute allowance, it means the cost may be approx. 51.8 p per minute.
As 0345 is in the 03 range, it’s subject to the same rules & rates as regular landlines under UK regulation.
Why 0345 Numbers Remain a Good Option:
Callers are charged no more than they would be for a standard UK landline call. In addition, many BT plans already include landline calls, meaning 0345 calls are often free for users. That makes 0345 a fair, predictable and transparent number choice for businesses – avoiding the confusion and high cost associated with some older non-geographic prefixes.
Handy Hint: Double Check with BT:
- If your plan includes free calls to UK landlines i.e.01/02 (if so, 0345 should be included too.)
- What is your out-of-plan per-minute charge is for landline and mobile calls?
- Are there any connection or setup fees for calls made outside your allowance?
In Conclusion
In 2025, calling an 0345 number on BT is generally straightforward and affordable: if you’re on a standard landline or mobile plan with inclusive UK landline minutes, it will likely be free. If not, expect charges of around £0.30 to £0.52 per minute, depending on whether you’re on a landline or mobile. Remember, the exact cost depends on your individual tariff, so it’s best to check your BT bill or plan details before calling.
