After further consideration, I have reworked my previous reply and for convenience posted it in its new form.
Ofcom’s proposal for number reclassification has some reasonable points but unfortunately still retains the potentially confusing numbering system that will in time be exploited to the detriment of the consumer. I would avoid the confusion between calls that cost the same and are treated in all respects like the present 01 and 02 numbers and calls that cost more or are treated differently.
I would have 3 classes of number.
Normal numbers. Numbers that are charged at the normal rates as 01 or 02 and are treated in all respects like normal numbers (that is 0p/min on option 3 and 1866 etc )
Mobile numbers. 07 ("peronal numbers" moved out)
Premium/Special numbers. Numbers that exceed the cost of normal numbers or are not treated in all respects like normal numbers. I would confine those numbers to the “09" class only. The 11 digit 09 class can be subdivided into 090, 091, 092, 093, 094, 095, 096, 097, 098 and 099 each with 99,999,900 different numbers (allowing for 100 unusable combinations).
In summary I would propose:
01 geographic numbers (costing between 3p to 0p/min and included in “free” packages).
02 geographic numbers (costing between 3p to 0p/min and included in “free” packages).
03 non geographic numbers (costing between 3p to 0p/min and included in “free” packages).
04 reserved  if used, would cost between 3p to 0p/min and included in “free” packages.
05 reserved  if used, would cost between 3p to 0p/min and included in “free” packages.
06 reserved  if used, would cost between 3p to 0p/min and included in “free” packages.
07 for mobile phones only (“personal numbers” moved to 097)
08 freephone only (084x and 087x migrate to "09" or "03", depending on price structure required)
09 any landline number which cost more than the normal rate and/or is excluded from a consumers call options at 0p/min. This 11 digit “09" class can be split into 090, 091, 092, 093, 094, 095, 096, 097, 098 and 099 subclasses, each subclass having 99,999,900 different numbers (allowing for, say, 100 unusable combinations).
For example: 090 all calls at less than the normal rate, but not included in “free” call packages  eg internet dial up and lower cost revenue sharing. 091 charges above the normal call rate (say up to 10p/min) 092 charges above the normal call rate (say 20p/min) 093 charges above the normal call rate (say 30p/min) 094 charges above the normal call rate (say 40p/min) 095 charges above the normal call rate (say 50p/min to 150p/min) 096 charges above the normal call rate (reserved) 097 for so called “personal numbers” (now on 070). 098 fixed charge per call. 099 for adult lines.
