RegEx: Uk Landline, Mobile Numbers

I struggled with finding the right solution: -

I need a regex expression that matches all UK phone numbers and mobile phones.

So far this one seems to cover most UK numbers:

^0\d{2,4}[ -]{1}[\d]{3}[\d -]{1}[\d -]{1}[\d]{1,4}$

However, mobile numbers do not work with this regular expression or phone numbers recorded in one solid block, such as 01234567890.

Can someone help me create the required regex expression?

Will it be a regex?

Its main purpose is to determine the correct starting digit for an unincorporated number, followed by the correct number of digits. It does not display if the local subscriber number is 5, 6, 7 or 8 digits. He does not apply a ban on the initial "1" or "0" in the subscriber number, about which I can not find any information on whether these old rules are respected. UK phone rules do not apply to properly formatted international phone numbers from outside the UK.
