1/ The daddy of reuse websites is Freecycle, a free version of eBay where you can pass on unwanted items and giggle at the curious possessions of others. In the past year, I've managed to rid myself of a broken Hoover, a load of old flowerpots, some fairy lights and a dozen heavy patio slabs that were taking up a corner of the garden. Easy. I hardly had to move from the sofa. The best thing is the collector comes to you, so you can sit tight and wait for your unwanted gear to be carried out.
2/ As a personal favourite, I reckon the 'put it on the pavement' method also deserves a mention. It works like this. You leave unwanted belongings outside your house with a sign saying 'Please take me'. Obviously if no one does, you have to haul them inside and think again, but I'm always surprised what goes.
3/ Gumtree is a huge online noticeboard which started in Australia and now has sites in more than 40 cities across the UK and Ireland - find your nearest here. With a section devoted to free stuff, you can advertise your unwanted clutter.
4/ Another Freecycle wannabe, VSkips is free and works by offering each member a virtual skip to put their unwanted belongings into. Once uploaded other members can search skips in their area. Find your local group here.
5/ It still counts as free-giving, but with swap shops, you get something back. SwapZ is a good place to start with its 75, 000 members and 50,000 listings.
6/ Another thriving swap shops is iswap - particularly popular for consumer electronics, video games and mobile phones. There was even a Blackberry going when I looked this morning. Members place an advert for the item that they want to exchange and then wait for other members to suggest what they would swap for it.
7/ Here is another swap shop, which has been going since 2006. It operates a point system, where you swap for points rather than an actual item, then you use your points to get your mits on whatever item you'd like. Although it's free to sign up and swap, you can also buy extra points.
8/ For anyone who lives in North East London or Essex, it's worth trying Give or Take, which will advertise unwanted items and try to find them future uses. It grew out of the successful Forest Recycling Project.
9/ To donate furniture to people in need, visit the Furniture Reuse Network and contact your local branch here. If you've got stuff it wants, it'll collect from your door.
10/ A music, film and games exchange website, called Swap And Play, allows you to pass on stuff you're bored of, while getting fresh material from people in your area.
