Why does (Un)Beloved Leader Paul Diviani have an 0845 telephone number – 0845 3285788

Is it cheaper or more expensive for us to call him than a Blackdown Hills 01404 number?

According to this Wikipedia article :

“0845 numbers offer the called-party the chance to collect a premium of up to 2 pence per minute. Only a very few fixed line telephone companies include 0845 numbers in bundled call allowances, in which case the onwards revenue share payment is subsidised by the Originating phone company.”

and here is the “Which” magazine campaign

… “The companies that use 0844, 0845, 0870 and 0871 phone numbers can theoretically share the revenue from each call with the phone service operator – Virgin Media or Orange, for example – so the longer you stay on the line, the more the companies earn. ”
