Six self-sufficiency dos and don'ts
1. Do little and often.
"If you've got an allotment or a large veg patch you need to be able to put in an hour or two a day ideally," says self-sufficiency enthusiast Andy Hamilton.
2. Do think about storage.
Avoid waste and stretch the season by freezing, pickling or turning your produce into jams, chutneys or booze.
3. Do explore bartering systems.
It's a good way to manage your excess produce and enables you to get things you might otherwise have to buy.
4. Don't spend a fortune on kit.
John Harrison recommends sticking to the basics. "A spade, fork, hoe and pocket knife is all you really need," he says.
5. Don't rush it.
Experts say it takes about three years of trial and error to find out what produce grows well on your plot.
6. Don't take it too seriously.
"Although you're growing your own food make sure it's fun," says Pat Gardiner, who runs go-self-sufficient.com.
This is more usually a feature of car insurance but it can also crop up in contents, mobile phone and pet insurance policies. An excess is the amount of money you have to pay before the insurance company starts paying out. The excess makes up the first part of a claim, so if your excess is £100 and your claim is for £500, you would pay the first £100 and the insurer the remaining £400. Many online insures let you set your own excess, but the lower the excess, the more expensive the premium will be.
