Thanks for the comments! I appreciate everyone is in difficult times and a 15% reduction is not the worst outcome, but it is bad for my own personal situation. Thanks again
Can you not find some savings in your day-to-day spending to mitigate the loss?
Again, I don't know anything about you but consider:
Cancelling any memberships or subscriptions that are not essential and that you do not use
Downgrade your phone, TV, broadband, streaming services
Drink less booze!
Heating bills should be coming down with this warm weather but instead of cranking it up on cold nights - warm socks and a blanket go a long way.
Buy the essential foods ranges and buy the individual items of fruit and veg not the prepacked multiples. To be clear - take one of those little bags and fill it with a selection rather than paying for somebody else to have done already.
Go through all your direct debits and standing orders and work out what you can do with and what you can do without.
Forecast known upcoming bills and start putting a few quid a week aside now. Don't rely on expensive borrowing to pay it because you haven't saved.
Negotiate the commitments you do have. If you don't ask, you don't get. Be bold, be brave and see what else you can shave off.
There are loads of ideas and ways to save money. As above, you could also make it up by getting another part time job or role.
I am sure you can do this... good luck!
