NOT GOOD PRACTICE 
Each time you apply for a credit card or loan (or insurance with monthly payments)
A mark is left on your credit file
A ‘hard credit search’ is done
This is visible for up to 12 months – though the impact reduces every 3 months or so.
Numerous ‘hard searches’ affect your credit report – it makes lenders think you’re desperate for money.
It is a good idea to space out credit applications ideally by at least six months.
