Recycle old mobiles

This is the easiest form of decluttering, as there's a whole industry set up to help. If you have an old mobile phone lying around the house, several companies will happily take the relegated beast off your hands. Not only could this bag you as much as £160 but, by not throwing it out with the rubbish, you'll also be doing your bit for the environment.

How much? It depends on the phone and demand, but some of the higher-end handsets will easily net more than £100. It only takes five minutes to check out what yours are worth.
