Anybody annoyed by being the subject of an SPD or sole occupant or single person discount review might usefully ask the council for a print off of their ICT-based records.
These really complete the picture of the nonsense stated originally by Experian, together with the London Borough of Hillingdon.
Depending upon the ICT system in use, there is a column headed 'allowances'. This heading explains why so many clowns insist on saying that the SPD is 'in payment'. Some clot sees the word 'allowances' on a computer screen and assumes that people are being paid an 'allowance'.
Under this heading the words 'disregard discount' may appear. This explains why so many people think that there is such a thing as a 'disregard discount'. You won't get the code 'disregard discount' and the code 'single' on the same account at the same time.
This explains why the ICT geeks responsible for the original NFI cock up must have been full of glee when somebody put the idea to them that you could 'check' whether a person was entitled to a 'single person discount' by looking at the electoral register.
If the Information Officer at your council is a complete idiot she will tell you that your records do not contain any codes, that they provide details of discounts that you are claiming and that these records are self explanatory.
And I could name at least one council where the Information Officer appears to be a complete idiot.
But that is for another day.
