Best % of limit for credit limit increases

js78

what is the best % which promotes the largest credit limit increases?

i have capital one 34% interest, vanquis, aqua and flybee.

20-30%?

if so do you just set up direct debit every month for the min payment then 6mths later how much should it go up?

Aqua £350 limit
Capital £200
Vanquis £250
Flybe £1000

How long do you recommend keeping these accounts open for credit scoring increase

hi cap1 will automatically increase on ur 4th statement.
if i was you, i would keep my debt to credit ratio no more than 70%

and run these accounts for at least 12 months and move to main stream.

hope this helps as thats how i boosted my credit file
