First and foremost, if your old fridge is in working order, you could give it to a friend, neighbour or family member. There are also a number of websites dedicated to reusing working appliances such as Freecycle. Some second hand dealers may be interested in your appliance if it's in good condition. You could also sell it yourself by placing an advert in the local paper, on a local website such as Gumtree or open up to a wider audience using eBay. There can be complications with these methods including difficulties arranging transportation for bulky items. It is also worth noting that the majority of fridges still contain substances that could be harmful if handled incorrectly.
