Who Pays for 0800 Calls? The Business Does
UK callers pay £0. The business that owns the 0800 (or 0808) number pays the inbound Freephone charge. Connecting a call across networks always costs money; Ofcom’s 2015 rules put that cost on the receiving company, not the customer. Full caller-side rules: are 0800 numbers free?
Key Takeaways
- The business pays. The company that owns the 0800 number absorbs the entire cost of the inbound call.
- The caller pays nothing. Thanks to Ofcom regulations introduced in 2015, callers on UK mobiles and landlines are not charged a single penny. Full detail: are 0800 numbers free?
- It is called "toll-free" or "Freephone" routing. Instead of the caller's network billing the caller, the receiving network bills the business owner a small per-minute fee.
- Mobile calls usually cost the business more. Telecom providers typically charge businesses a slightly higher inbound rate when the call originates from a mobile phone versus a landline.
When you dial a UK 0800 number, the billing is effectively reversed. Your phone network carries the call for free, and the telecom provider hosting the 0800 number bills the business a per-minute rate to receive it.
How the Financial Flow of an 0800 Call Works
To understand exactly who pays what, it helps to look at the journey of an 0800 call from the moment a customer dials the number to the moment the business answers.
Step 1: The Originating Network (The Caller)
Let's say a customer dials an 0800 number from their O2 mobile. Under Ofcom rules, O2 is legally prohibited from charging the customer for this call. It does not use their inclusive minutes, and it will not appear as a charge on their monthly bill.
Step 2: The Access Charge
O2 still has to route that call across their infrastructure. To compensate O2, the telecom network that hosts the 0800 number (for example, UKTollFree.com) pays an "origination fee" or "access charge" directly to O2.
Step 3: The Termination Rate (The Business)
To cover the cost of paying O2, plus the cost of providing the call routing software and infrastructure, the telecom provider bills the business owner an inbound per-minute rate.
How Much Does It Cost a Business to Receive an 0800 Call?
The cost to the business depends entirely on their telecom provider and the pricing plan they have chosen. Most modern providers charge businesses an inbound rate between 2p and 5p per minute.
However, there is an important distinction in how these inbound rates are calculated. The cost to the business often changes depending on where the call originated:
| Call Origin (Caller's Device) | Cost to Caller | Cost to Business (Example) |
|---|---|---|
| UK Landline (BT, Sky) | Free (£0.00) | Usually the lowest rate (e.g. 2p/min) |
| UK Mobile (O2, EE) | Free (£0.00) | Usually a higher rate (e.g. 4p/min) |
| UK Payphone | Free (£0.00) | Often carries a fixed surcharge |
Because mobile networks demand higher origination fees to carry the call, most 0800 providers pass that cost onto the business by charging a higher per-minute rate for calls coming from mobiles.

If an 0800 Freephone number costs the business money every time the phone rings, why do thousands of UK companies use them instead of standard local numbers? The answer comes down to consumer psychology and conversion rates.
1. Increased Call Volume and Sales
When consumers know a call is 100% free, the psychological barrier to picking up the phone is lower. Many businesses switch from a geographic number (like an 020 London number) to Freephone specifically to make enquiry calls easier. For a business, paying a few pence per minute for a short sales call is often a cheap price to pay to acquire a new customer.
2. National Presence and Trust
0800 numbers carry a strong reputation in the UK. They are associated with established, highly-trusted organisations like the NHS, major banks, insurers, and national charities. By using an 0800 number as a small business, you immediately elevate your brand's perceived size and reliability.
3. International Companies Operating in the UK
For US companies or Australian businesses expanding into the UK market, an 0800 number is the perfect tool. The business doesn't need to open a physical office in London; they can simply route their 0800 calls internationally to their existing overseas call centre. The UK customer dials a free local number, completely unaware the call is being answered abroad. See toll-free vs Freephone for how US teams usually find UK Freephone.
If overseas clients need to call you into the UK, remember Freephone is not free from abroad — publish a UK local or mobile in +44 format as well (Aancall can supply these). Formats and dialling steps:

How Do Bundled Minute Plans Work?
To make billing simpler, many modern VoIP and SIP providers (like UKTollFree.com) offer monthly subscription packages that include a set number of inbound minutes.
For example, a business might pay £14.99 per month for their 0800 number, and that package includes 100 inbound minutes. If the business receives exactly 100 minutes of calls that month, they pay nothing extra. If they receive 150 minutes, they are only billed the per-minute overage rate for the final 50 minutes. This allows companies to easily forecast their telecom expenses.
