OP, just follow the reset procedure as posted.
And there's no specified format under the regs for a CC, all that's stated are the criteria....and SCC's CC misleads as regards their power to demand the surcharged penalty by issuing a CC. It's a convoluted issue in that whereas non-payment means the surcharged penalty is owing, this may not be demanded until the expiry of specified time periods, examples being:
Where an appeal has been registered, 28 days after an adjudicator has issued their direction; or
28 days beginning on the day a NOR is served...(which of course could then morph into an appeal)..etc..
@John U.K, oddly enough there's no requirement to include the regs or Act on any notices, but it seems to be universal practice.
