Where can i direct my customers to mail there "returned purchases" to instead of...

...me giving my home address? I'm an online retailer and i do not have an office, i operate from home. From time to time my customers return back their items to me in which i have to give my home address. Are there any companies in the uk/ london which solve this problem by allowing me to direct my customers to return their purchased items via that address. Also the company must also be able to forward the returned stock to my address or be close enough for me to pick it up. I'm located in london. Thanks :S
