     Exploit your parking space

     An unused parking space or garage can make money. If you live near a city center or an airport, you

could make anything up to￡200 or￡300 a week. Put an advertisement (广告) for free on Letpark or

Atmyhousepark.

     Rent (出租)a room

     Spare room? Not only will a lodger (房客)earn you an income, but also, thanks to the

governmentbacked "rent a room" program, you won't have to pay any tax on the first ￡4,500 you make

per year. Try advertising your room on Roomspare or Roommateeasy.

     Make money during special events

     Don't want a fulltime lodger? Then rent on a shortterm basis. If you live in the capital, renting a room

out during the Olympics or other big events could bring in money. Grashpadder can advertise your space.

     Live on set

     Renting your home out as a "film set" could earn you hundreds of pounds a day, depending on the film

production company and how long your home is needed. A quick search on the Internet will bring up

dozens of online companies that allow you to register your home for free-but you will be charged if your

home gets picked.

     Use your roof

     You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment

(around ￡14,000)and let you use the energy produced for nothing. In return, they get paid for unused

energy fed back into the National Grid. However, you have to sign a 25year agreement with the supplier, which could prevent you from changing the roof.
