     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

government-backed "rent a room" program, you won't have to pay any tax on the first  ?4500 you make

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

     Make money during special events

     Don't want a full-time lodger? Then rent on a short-term 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 25-year agreement with the supplier, which could prevent you from changing the roof.
