End the 5 week wait for first payment.
Have the choice to be paid weekly, fortnightly or monthly available to everyone, without having to plead and prove a special need.
Raise the level of UC payment so that all over 18s receive the same basic rate.
Allow claims and communications in person, by post and online by everyone without having to plead and prove special need.
I would have benefitted greatly from most of these changes being in place and it would make the claiming and communications process a lot more manageable and less stressful for me. Raising the payments for younger people would go some way to relieve poverty - food and rent doesn't cost less for under 25s. Being paid weekly or fortnightly would make it easier for me to budget and manage bills more confidently.
