Are 0800 & 0808 Numbers Free to Call? (UK 2026)

If you are asking are 0800 numbers free, the short answer is yes. Since 1 July 2015, calls to 0800 and 0808 numbers have been completely free to dial from both UK landlines and UK mobiles. There is no catch, no small print and no per-minute charge passed to the person making the call. Before that date freephone numbers were free from landlines but most mobile networks quietly added a charge, which is why so many people still assume calling an 0800 number from a mobile costs money. It does not — not any more.

This guide explains what changed, how 0800 and 0808 differ, who actually pays for a freephone call, and how the freephone ranges compare with the other UK number prefixes you see advertised.

The short answer: 0800 and 0808 are free to call

Both 0800 and 0808 numbers are free to call from any UK landline or mobile. They sit in the "Freephone" category, the only group of UK numbers that are genuinely free to the caller in every situation.

The change came in July 2015 as part of Ofcom's "UK Calling" reforms, which were designed to make phone charges clearer. Before then, mobile networks were allowed to bill customers for calls to 0800 and 0808 numbers even though landline callers paid nothing. That inconsistency confused people and made businesses nervous about advertising a freephone number at all. The reform closed the gap: freephone became free for everyone.

So to be precise about the common searches:

• Are 0800 numbers free? Yes, from landlines and mobiles.
• Are 0808 numbers free? Yes, identical rules.
• Is 0800 free from mobile? Yes, since 1 July 2015.
• Are 0808 numbers free from mobile? Yes, same date, same rule.

0800 vs 0808: what's the difference?

For the caller, there is no practical difference at all. Both ranges are Freephone and both cost nothing to dial. The distinction is about who tends to use them.

• 0800 is the original and most widely recognised business freephone range. If a company wants customers to call its sales line or support desk without hesitation, it usually picks an 0800 number.
• 0808 is functionally the same Freephone range and is heavily used by helplines, charities and support services. Many of the best-known national helplines use 0808 numbers, partly because some of them are also free to call from payphones and are excluded from billing in ways that make them ideal for confidential support.

If you are choosing a number for your own business, do not overthink the 0800-versus-0808 question. Both signal the same thing to a caller: this call will not cost me anything. The recognition factor of 0800 is slightly higher for commercial use, but neither is wrong.

So who actually pays?

Freephone is free for the person dialling, but the call still costs money to carry. That cost lands on the business that owns the number.

When you run a freephone number, you pay a per-minute receiving charge for every call that comes in. The longer the call and the more calls you take, the more you pay. That is the entire bargain of freephone: you remove every barrier to the customer picking up the phone, and in exchange you absorb the cost of the call yourself.

For most businesses this is money well spent, because a freephone number visibly says "we want to hear from you" and tends to lift call volumes. But it does change the maths in one important way. If you are paying per minute to receive calls, the worst outcome is paying for a call that rings out, goes to a clumsy voicemail, or gets answered badly and the caller hangs up. You have taken on the cost without getting the customer.

That is the part that matters far more than the prefix on the number. Whether you advertise an 0800, an 0808 or an ordinary geographic line, the question that actually moves the needle is whether those calls get answered properly. A missed call on a freephone number is the most expensive kind of missed call, because you may even be paying to miss it.

This is where a virtual receptionist earns its place. An AI receptionist like Orval answers every call in your business name, 24/7, books appointments and captures leads, for a fixed price from £19.99 a month with no per-minute fees of its own. It does not change what your phone network charges to carry the call, but it does make sure that the call you are paying to receive turns into a booked job or a captured lead rather than a dropped one. If you are weighing up how to handle calls overall, our guide to the best small business phone system walks through the options.

UK number prefixes and what they cost the caller

Freephone is only one part of the picture. Here is how the main UK ranges compare from the caller's point of view.

A few things are worth drawing out from that table.

084 and 087 are not free

The 084x and 087x ranges are "Service numbers" and they cost the caller money. Under the same 2015 reforms, the price was split into two clearly labelled parts: an Access Charge set by the caller's own phone provider, and a Service Charge set by the business and shown wherever the number is advertised. So if you see "calls cost 7p per minute plus your phone company's access charge," that is the Service Charge being declared. These numbers are the opposite of freephone, and many customers hesitate before dialling them.

09 numbers are premium rate

The 09x range is premium rate and the most expensive category of all. It exists for things like competition lines and specialist services, not everyday business contact. If your goal is to make it easy for customers to reach you, this is the range to avoid.

03 numbers: the free-feeling middle ground

The 03 range (0300, 0330, 0345, 0370) is the one many businesses reach for when they want something that feels free without paying freephone receiving charges. By regulation, calls to 03 numbers must cost the caller exactly the same as a call to an 01 or 02 geographic number, and they must be included in any inclusive or bundled minutes the caller has. They are not literally free, but for the vast majority of people on a modern mobile or landline plan they cost nothing extra to dial. For a small business that wants a single national-looking number without a per-minute bill, an 03 number is often the pragmatic choice.

If you would rather stick with a local-looking number, our reference on UK area codes breaks down the geographic 01 and 02 ranges by region.

What this means for your business

Pulling it together:

• 0800 and 0808 are genuinely free to call from every UK landline and mobile, and have been since July 2015.
• The caller pays nothing; the business pays a per-minute charge to receive freephone calls.
• 084 and 087 cost the caller money (Access Charge plus Service Charge), and 09 is premium rate and dearest of all.
• 03 numbers are charged like ordinary geographic calls and come out of inclusive minutes, making them a popular, near-free alternative.

Choosing the right prefix is a sensible decision, but it is a small one next to a bigger truth. The number on your advert only does its job if a real, helpful answer is waiting on the other end. A freephone number with no one to pick up is just a more expensive way to miss the customer.

So pick the range that fits your brand and your budget, then make sure every call gets answered. That is the part your customers will actually remember.

Frequently Asked Questions

Are 0800 numbers free to call from a mobile?

Yes. Since 1 July 2015, calls to 0800 and 0808 numbers have been free from UK mobiles as well as landlines. Before that date they were free from landlines but most mobile networks added a charge.

Is there any difference between 0800 and 0808 numbers for the caller?

No. Both 0800 and 0808 are Freephone ranges and both are completely free to call. 0808 is widely used by helplines and charities, while 0800 is the general business freephone range, but the caller pays nothing either way.

If the caller doesn't pay, who pays for a freephone number?

The business that owns the number pays. Freephone numbers carry a per-minute receiving charge billed to the number's owner, which is the whole point — the caller dials for free and the business picks up the cost.

Are 03 numbers free as well?

No, but they are close. Calls to 03 numbers (0300, 0330, 0345, 0370) cost the same as an 01 or 02 geographic call and count towards any inclusive minutes on your plan, so for most callers they feel free without being technically free.
