// freephone decision

When should a small business use an 0800 number?

Use 0800 when the value of more calls is likely to beat the extra freephone call cost. It is strongest when the number appears in places where a caller has not decided yet.

What is an 0800 number?

An 0800 number is a UK freephone number. It is free for people calling from UK mobiles and landlines, while your business covers the received call cost and forwarding.

What about 0808?

0800 and 0808 are both UK freephone ranges. Customers usually treat both as free to call, so choose the number pattern you prefer or port the number you already advertise.

Where does 0800 work best?

Use it on adverts, quote pages, customer support routes, packaging and offline material where removing caller cost can improve response.

How fast can it go live?

A new 0800 number can be chosen and routed in minutes. Porting an existing 0800 number usually takes longer, but keeps the number your customers know.

Use 0800 when removing caller cost matters more than the extra freephone call charge. Use 0333 or a local number when you want a lower-cost business line.

Frequently asked questions

What is an 0800 number?

An 0800 number is a UK freephone number. It is free for people to call from UK mobiles and landlines, while the business that owns the number pays the received call cost and any forwarding.

Who pays for 0800 calls?

Calls to 0800 numbers are free for the person calling from UK landlines and mobiles. As the business, you pay for the calls you receive and forward from your LineHQ calling credit.

How much do 0800 calls cost my business on LineHQ?

LineHQ packages start at £4.99 a month with no setup fee and no contract. On Pay As You Go, 0800/freephone calls are billed from 8p/min inbound, 10p/min when forwarded to a UK landline or 12p/min when forwarded to a standard UK mobile.

What is the difference between 0800 and 0808?

0800 and 0808 are both UK freephone ranges. For callers, the important point is the same: the call is free from UK mobiles and landlines. The choice usually comes down to available number patterns or keeping an existing number.

How quickly can I set up an 0800 number?

A new 0800 number can be searched, chosen and routed in minutes. Add calling credit, choose where calls should ring, set any opening-hours rules, and the line can start receiving calls without a physical install.

Can I get an 0800 number and keep my mobile?

Yes. Your 0800 number sits in front of your existing phones and can forward calls to your mobile, office line or team without a physical line install.

Are 0800 numbers good for small businesses?

They are useful when you want customers to call without hesitation: sales lines, quote requests, adverts, customer support and complaint routes. If most callers already know you, or you mainly need a low-cost business line, a local number or 0333 number may be more efficient.

When should I choose an 0800 number?

Choose 0800 when the call is valuable enough that you want to remove caller cost completely, such as new enquiries, consumer sales, printed adverts, support lines and quote requests. Choose 0333 or local when caller cost is less of a barrier and you want lower received-call costs.

Are 0800 numbers free to call from mobiles?

Yes. Since 2015, calls to 0800 numbers have been free for the person calling from UK mobiles as well as landlines. That removes any hesitation about the cost of ringing you, which is why freephone numbers tend to lift response rates on adverts, packaging and websites.

Can I port my existing 0800 number to LineHQ?

Yes. Most existing 0800 freephone numbers can be ported across to LineHQ for free, so you keep the number your customers already know. It carries on working throughout the transfer and switches to LineHQ forwarding on completion, typically within a couple of weeks.

Can I record and screen calls to my 0800 number?

Yes. An 0800 line gets the same call handling as every LineHQ number: optional recording with a spoken consent prompt, voicemail-to-email, a virtual receptionist, and a spam-call blocklist so nuisance callers cannot quietly run up your freephone minutes. It all forwards to whichever phone you choose.
