The copper switch-off and your 020 line
BT and Openreach are retiring the old copper phone network (PSTN), moving UK landlines to digital, with the switch-off due to complete by January 2027. If your City of London business still has a traditional landline or ISDN, you will need to move — and it is a good moment to put a receptionist on the number at the same time. You keep your 020 number either way.
What the switch-off means for your business →Holidays: England has eight bank holidays a year, including Easter Monday and the late-May and August bank holidays. Set your own closures and it tells callers you’re shut rather than booking them in.

Do I have to change my 020 phone number?
