A small number of 084x and 087x numbers still remain in use for a limited number of functions.
Correctly format the 084x or 087x number (with leading 0, and without +44? - to signify not widely accessible from abroad).
Remove any reference to "local rate", "lo-call", or "national rate" as this hasn't been true for 0845 or 0870 numbers since before 2004, and has never been true for other 084x or 087x numbers.
Add the required premium rate call charge declaration, as required by Ofcom and ASA since 1 July 2015, something similar to: "Calls incur a XX pence per minute service charge, plus your phone provider's per-minute access charge."
Correctly format the respective 01xxx or 01xxxx number (with leading +44, and with correct length area code and local number as shown below) in the 18 "mixed" areas.
