As a tenant, I was always supplied with a TV, Toaster, Kettle, Microwave, cutlery, delph, and pots and pans - Believe you me, I did leave in plenty of rentals in my time.
Only on one occasion was I supplied with duvet & linen and whilst it was appreciated, I really preferred my own and one of the first things I did when I moved into that rental was put my own items on the bed.
Mattress protectors are essential - seriously! But again change them every time you change tenants.
As a word of advice, you might want to itemise the television (if you choose to provide one) on your lease, along with a guide value, and place a clause that if it is damaged, it will then have to be replaced with one of equal value. Also, remember to make the TV licence either your responsibility or that of the tenant and make that very clear!
