Whether you’re on a contract SIM or a pay-as-you-go plan with Vodafone, the cost to dial a 0300 number in 2025 is clearer and more regulated than ever – but there are still important details to check.
Below is what you need to know now:
1. What the law says in 2025
- Numbers beginning with 03 (including 0300) are classified as non-geographic numbers that must be charged at the same rate as standard UK landline calls (i.e. numbers starting 01 or 02).
- Calls to 03 numbers must count toward your inclusive minutes if your plan includes them—just like 01/02 calls. Revenue sharing (where part of the caller’s cost is shared with the called party) is not allowed for 03 numbers.
- From 1 February 2025, Ofcom took over full regulation of premium-rate and non-geographic number services (replacing the Phone-paid Services Authority).
- Under the “UK Calling” reforms (implemented earlier), organisations using non-geographic numbers (08, 09, 118) must clearly display “calls cost x p/min + your phone company’s access charge.” That requirement still applies to service numbers (08/09).
- However, because 03 numbers are tied to geographic rate, there is no extra service charge beyond what you’d pay to call 01/02 under your plan.
- So in 2025, calls to an 0300 number should behave just like standard landline calls – no hidden premium.
2. What Vodafone customers can expect to pay (2025)
- Vodafone’s published charges for calls from its Home Phone/fixed-line service show that calls to 01, 02, and 03 numbers carry a call connection charge of 19p and then a per-minute rate of 11.5p (daytime, evening, weekend) for those numbers. Vodafone
- That means if you make a call from Vodafone’s Home Phone, a 5-minute call to an 0300 number might cost:
- Connection: 19 p
- Per-minute: 5 × 11.5 p = 57.5 p
- Total: 76.5 p
- On mobile plans, 03 numbers are typically included in inclusive minutes. Outside those, your mobile operator’s standard charge for calling 01/02 would apply. For Vodafone in particular, this is the same as any other landline call when out of bundle. (Exact rates depend on your specific tariff.)
3. Why this matters for your business or service line
- Because 03 numbers are regulated to mirror geographic call costs, they present a more friendly and transparent alternative to 08/09/118 numbers, which carry extra service charges and require access-charge disclosures.
- Organisations using non-geographic service numbers (08/09) still must display the cost clearly (“calls cost x p/min + your phone company’s access charge”). That means callers are more informed than ever.
- If your operations rely heavily on customer calls (helplines, support desks, etc.), using 03 numbers can improve trust and reduce caller resistance (since people know they’re not paying extra).
