1. Rent your garage or driveway
If you have a garage or driveway you’re not using, you could rent it out for others to park in.
You can let your garage through a property-letting agent, particularly in major cities which can be even more lucrative if you live near a train station.
You could just rent out your driveway by advertising in your local paper or newsagent.
Websites such as parklet.co.uk or JustPark allow you to advertise your available space.
You could also use the online notice board at www.gumtree.com - but remember that you’ll have to work out contracts and payments yourself.
But it's worth remembering that if you change the location where you usually park your own car (in order to rent a garage or driveway), you should notify your insurer as this may affect your premium.
2. Recommend a friend
There are plenty of deals to take advantage of by simply recommending a friend. In many cases, for each one of your referrals, you’ll receive a gift, and your friend will get the same.
For example, Sky customers can invite friends to join Sky TV. Both yourself and the friend will be rewarded with up to £75 in vouchers for each friend who joins.
