[uknof] OFCOM requirements on timeliness to get a MAC from ADSL or FTTC provider?

[Paul Mansfield]

A friend wants to change provider from M247/webtap to Fido, and has been
quoted it'll take five days to be given the code!

That doesn't seem reasonable to me.

Do OFCOM have a timeliness requirement on ISP's handing over porting codes?
