Saving up an emergency fund is known as self-insurance and everyone should do it. You should pay some money by standing order each month into a high- interest account that is completely separate from your other affairs and that requires no more than a week's notice to access.
Standard Life (0345 555657) pays 5.35 per cent gross on pounds 1 upwards and allows you to run several linked accounts. You can get a higher overall rate of interest but keep your savings separate from the emergency funds. If you have access to the internet, an Egg account (www.egg.com) offers the same deal (including linked acounts) and pays top interest rates of 6 per cent.
If you do decide you want to buy insurance then consider no-frills policies which allow you to keep costs down by paying a high excess - that is, the first part of a claim which policyholders must pay themselves. In return you will get a reduction in premium.
Some types of insurance, on the other hand, are of such dubious value that it may be worth trying to do without. Extended warranties are a good example. Insuring a pounds 1,500 personal computer for five years will cost you around pounds 500 in a single payment. Saving that much in a self-insurance account would give you a decent lump sum towards a new computer after five years.
Most of the cover your extended warranty is buying during the first year is just duplicating what is already provided by your free manufacturer's warranty.
Other less-than-value-for-money insurance is that offered by accident, sickness and unemployment cover to protect a mortgage, although standards will be raised by new rules due to be introduced in the summer. Pet insurance can also be a waste of money, especially for very old or unusual pets.
The bulk of insurance needs tend to fall within three main categories : home, car and family. Here are some low-cost ways of dealing with them:
Household policies. For home contents insurance, in particular, there has never been a better time to buy. Premiums on average cost around two thirds of what they did five years ago. Those feeling the pinch can consider no-frills contents policies that can be as little as pounds 50 a year in rural parts of England. These provide peace of mind by covering the major risks such fire, theft and water damage but exclude cover for accidental damage or loss of personal possessions outside the home.
Most motor insurance also remains good value but it may be worth seeing a broker to discuss what type of cover to buy. Cover for third party-liability is compulsory and in practice most people buy policies that also protect their own vehicle against fire and theft. It can sometimes be worth cutting back on comprehensive cover - which also covers your own vehicle against accidental and malicious damage and can include extras such as windscreen cover and towing charges.
Robin Belsom, at Colin Ryan Insurance Brokers in Ipswich, says: "If someone is under 21 and their car is worth pounds 1,500 because it's eight years old, I would question the value of comprehensive cover because it will probably cost twice as much as third party, fire and theft and involve a compulsory excess of pounds 300 or pounds 400.
"For older drivers, on the other hand, the difference in cost between third party, fire and theft and comprehensive cover is often as little as 20 per cent. Indeed we've had cases when they've cost the same."
Covering the family can throw up the biggest headaches because life cover, critical illness cover and permanent health insurance tend to involve high payouts that no one can realistically hope to pay from savings. Premiums, particularly for the two health-related covers, can be significant and some families on tight budgets may have little choice other than to go for the bare minimum - a life policy that pays out on death.
Don't ever get bogged down by paying for insurance you cannot afford. Penny O'Nions, principal at The Onion Group, an IFA in Amersham, says it is important to keep a sense of perspective.
"All insurance is a gamble and you must weigh up the odds of actually ever having to claim," she says. All too often, there is a great onus on having protection in place and, while this is important, it shouldn't be to the detriment of other requirements, such as food, clothing and holidays."
