Do childminders need to have a landline?

I know that childminders need to have access to a phone in order to make emergency calls. Do we have to have a landline or can the phone be a mobile?
I no longer use my landline but am wondering if I need to keep it for childminding?

We used to have to have one many years ago when we used the National Standards - it disappeared from the EYFS ... so it's up to you.

You need to think about what would do in an emergency if your mobile phone didn't work :D

The thing about modern day landline phones is that if they plug into a plug socket they will not work in a power cut. Even a wire free, cordless one, will only work if the base unit is working.

Old fashioned phones with dials used to work when there was a powercut.
