How Three handles calls to 0345 numbers
If you’re trying to work out how much it costs to phone a 0345 number from your Three mobile, this guide breaks it down for you.
Numbers beginning with 0345 sit within the wider 03 range, so they must legally be charged at the same rate as UK standard landline numbers (01/02). This rule is set by Ofcom and applies across all mobile and landline networks.
Three’s pricing depends on the type of plan you’re on as follows:
- Contracts with unlimited or inclusive minutes.
These plans normally treat 0345 calls as standard landline calls, so they typically come out of your inclusive minutes at no extra cost. - Contracts with a set number of minutes.
If you’ve used up your allowance, calling a 0345 number will switch to Three’s out-of-plan rates. These can be around 55p per minute. - Pay-As-You-Go (PAYG).
PAYG users without add-ons or bundles usually pay a flat per-minute charge. Past figures suggest around 35p per minute for Three PAYG customers.
As Three doesn’t always list 0345 rates directly in their price guides, it’s always worth using their number checker or plan details to confirm.
At-a-Glance Price Table (Three Mobile)
| Three Plan Types | Monthly Cost | Price to Call 0345 Numbers | Key Notes |
| Contract with inclusive landline minutes | Varies | Included (same as 01/02 calls) | Most mid-to-high tier plans include these. |
| Contract with limited minutes | Varies | 55p per minute | Charged once you exceed your allowance. |
| Pay-As-You-Go (no add-ons) | £0 base | 35p per minute | Standard PAYG rate, subject to change. |
Please note: Three may amend pricing, so you should check your exact tariff.
Are you a business advertising a 0345 number?
Here are some handy hints to remember:
- Highlight that 0345 numbers cost the same as calling landlines.
- Remind callers that most mobile customers (including those on Three) will have these calls included in their monthly allowances.
- Provide clear, compliant pricing wording such as:
‘Calls to our 0345 number are charged at the same rate as calls to standard UK landlines and may be included in your mobile or landline call plan.’
Such reassurance helps callers avoid confusion, particularly PAYG users who may face per-minute charges.
Final Summary
Three customers with inclusive minutes will usually pay nothing extra to call 0345 numbers. PAYG users or those outside their allowance may pay 35p – 55p per minute, depending on the plan type. Ofcom regulations mean 0345 numbers must be charged the same as 01/02 calls – a key point for both callers and businesses.
