White goods etc. for new council flat. (Kettering NN16)

Hi everyone, I currently live in shared temporary accomodation after being made homeless by my ex back in February.
I have been offered a flat which will be available to view & move into on/after June 20th.
I need a lot of stuff and I am especially struggling with getting big things like white goods (cooker, washing machine, & fridge-freezer).

Any help would be gratefully received.
