Where to donate surplus bedding

My charity shop sells clean bedding sheets pillowcases blankets etc (but not duvets themselves) towels are sold 50p for pets
Worth a ring round

The Salvation Army charity shop here always welcomes bedding, towels too.

My local Cat and Dog shelter will take sheets, blankets and towels, but not duvets - I expect they’re difficult to launder.

Put on Freecycle or Olio.

local refugee centre.
foodbank.
homeless centre.

I volunteer with Barnardo’s and we take clean, good quality sheets, pillow cases and duvet covers.

I have just put a bag of duvet covers and sheets in the Firemans Fund bin outside the Fire Station.

Dogs Trust are always happy for less than perfect duvets, towels etc.

We have a charity 'Changing Lives' which furnishes flats for homeless people, abused women etc. They ere always glad of bedlinen

Dunelm and Tesco both take bedding where I live.

Animal charities are always welcoming to donations of bedding.

We have two local charities, one for families in need and one for victims of domestic abuse who’ve been rehoused, both get any spare things from us.
Facebook is a good start, there are quite often free/giveaway sites on there.

Some charity shops do sell them, phone your local ones. The quality is really irrelevant it is still second-hand bedding.

You could try your local Facebook “ In need” pages or freecycle.
