Calling 0300 numbers in the UK can sometimes be confusing, so let’s clear things up for 2025. These numbers are part of the 03 number range, which Ofcom regulates. By law, calls to 03 numbers must never cost more than calls to standard UK landlines (those beginning with 01 or 02).
That means the cost of a call to a 0300 number will depend on whether you’re calling from a landline or a mobile and whether the call is included in your tariff.
How Much Does it Cost to Call 0300 Numbers?
- From a landline: Up to 16p per minute (in line with 01/02 call charges).
- From a mobile: Typically between 3p and 65p per minute, depending on your provider and tariff.
- Included minutes: Many mobile and landline packages now include 03 numbers within bundled minutes so that the call could cost you nothing extra.
So while 0300 numbers are not “free” by default, their cost is capped and fair compared to premium numbers.
Sky Talk and 0300 Numbers
If you’re using Sky Talk, 0300 calls are treated just like any other 01/02 landline call.
- With Sky Talk Anytime Extra and similar inclusive packages, calls to 0300 numbers are free (included in your monthly fee) during the inclusive periods.
- Outside of inclusive times, or if you don’t have an inclusive package, you’ll pay the standard per-minute rate plus a 25p connection charge for each timed call.
This means that in many cases your call could be included and cost nothing extra — but if it isn’t, you’ll see the small connection fee and per-minute charge on your bill.
