Experian taking ages to update electoral roll?

£££saver

I know this is old but I have the same (ish) issue.

Only difference is Equifax are showing it and Experian aren't, therefore I must obviously be on the roll if Equifax have it.

I ordered both £2 reports within the last week, and registered with the new council around early October 11, so it's been just over 3 months.

Did the above posters managed to sort their's out? And should Experian's databases be updated within a couple of months if Equifax already has, or do they do them annually or bi-annually?
