You can request to increase your limit to a higher amount at any time. However, the increase will only be implemented 24 hours after the request is made and you will need to confirm the new limit on the ‘Deposit limits’ page before depositing again.

For example, if you increased your limit from £10 a week to £20 a week, you'd need to confirm the change 24 hours after the initial request to change. Once confirmed, your new limit would begin on the upcoming Sunday night at 00:00 GMT / 01:00 BST. 

Navigate via > Safer Gambling > Spending controls > click 'Set Deposit limits' and scroll to the bottom of the page to accept or decline the new limit.
