0330 numbers are part of the UK’s non-geographic 03 range, typically used by businesses of all sizes. Unlike premium-rate 08 or 09 numbers, 03 numbers are never more expensive than calling a normal landline and are included in any inclusive minutes offered by your provider.
TalkTalk Call Costs to 0330 Numbers (2025)
TalkTalk follows Ofcom’s ‘03 Number’ legislation, meaning that 0330 numbers cost the same as any UK landline call. The table below summarises the current 2025 TalkTalk rates:
| Type of Call | Cost per Minute (2025) | Included in Bundles? | Notes |
| Landline to 0330 | 12.5 p per minute (inc. VAT) | Yes, if your plan includes calls to 01/02 numbers | Billed per second after the first minute |
| Mobile to 0330 (TalkTalk Mobile) | 25 p per minute (inc. VAT) | Yes, if your mobile plan includes UK landlines | Deducted from inclusive minutes |
| Out-of-bundle calls | Charged at the above rates | No | May vary by individual tariff |
Top Tip: If your TalkTalk plan includes ‘Unlimited UK Landline Calls’ or ‘UK Minutes’, then 0330 numbers will count towards that allowance. That means you’ll only pay extra once your allowance is used up.
Ofcom Rules on 03 Numbers (2025)
Ofcom regulations continue to ensure that:
- Calls to 03 numbers must cost no more than 01 or 02 calls.
- Calls must be included in any inclusive call bundles that include UK landline calls.
- Businesses and service providers cannot charge extra for receiving calls on 03 numbers.
- From January 2025, telecom providers must state all potential call charges in pounds & pence upfront, removing inflation-linked price rise clauses.
Such regulations make 03 numbers one of the most transparent and fair options for UK businesses to use when offering customer contact lines.
Example Costs:
How calling an 0330 number might look on a TalkTalk plan:
- During inclusive hours: £0.00 (included)
- Out of hours (landline): £0.125 per minute
- From TalkTalk mobile, no allowance left: £0.25 per minute
- 1-hour call from landline (no bundle): £7.50
Why Businesses use 0330 numbers
0330 numbers are a trusted choice for UK organisations because they:
- They are nationwide and not tied to a specific area.
- Give customers reassurance that calls cost the same as local rates.
- Can be routed flexibly to suit call centres, remote staff or IVR systems.
- Improve professional image compared to mobile or geographic lines.
To wrap things up:
In 2025, TalkTalk continues to charge standard UK landline rates for calls to 0330 numbers, following Ofcom’s consumer protection rules. Most TalkTalk customers won’t pay anything extra if their package includes UK landline minutes.
