How 0800 numbers work for your business...

An 0800 number is a non-geographical number that is pointed to an existing landline or mobile number. 

To have an 0800 number you don't need an extra line, wiring or any special equipment - you just need to provide an existing number for the 0800 number to be pointed at. This can be either a UK mobile or landline. 

You may also point an 0800 number to an overseas line - costs vary depending on the country.

What's really beneficial to you as a company is that an 0800 number allows customers to call you for free from any UK landline. This in turn shows that you care about providing a convenient service for your clients.

It is not free to call 0800 numbers from mobiles at present. However, it is frequently reported in the media that Ofcom are in the process of trying to change this in the near future. See: The Guardian article. 

You are charged for calls that are made to your 0800 number, but this isn’t as costly as you would imagine.  

What’s also convenient about an 0800 number is it can be pointed to different numbers during your day. When you are in the office you can have it pointed to your business landline and when out of hours to your mobile or even a voicemail to email. This rerouting service should always be free of charge, so be wary of companies that try and charge you for this service.

If for any reason the phone lines in your office go down you can quickly point your 0800 number to another working landline or mobile to avoid missing business.

Also, if you move premises in the future you just take the 0800 number with you by pointing it to your new landline. No need to change your advertising, stationary, email signatures etc.
