Comparing Life Insurance Policies: What to Check

Two life insurance quotes can look almost identical. Same amount of cover, same term, only a pound or two between the monthly premiums. So why wouldn’t you just choose the cheaper one?

Sometimes you can. But before deciding, it’s worth looking at what you’re buying. The price on its own won’t tell you whether the cover suits your mortgage, your children or the way your family would manage financially if you died.

Here’s how to compare life insurance policies in the UK without getting lost in the small print.

First, decide what the policy needs to pay for

It helps to start with the bills rather than the insurers. Are you trying to clear a mortgage, leave your partner enough money to pay the household costs, or provide an income while the children are growing up?

Take a couple with a repayment mortgage and two primary-school-age children. Clearing the mortgage would take a lot of pressure off the surviving partner, but it wouldn’t pay for food, heating, childcare or time away from work. They may want one amount of cover for the mortgage and another for the family.

Someone without dependants might come to a very different conclusion. Life insurance isn’t something everybody needs in the same amount, and existing work benefits or policies matter too.

For a starting point, see how much life insurance do I need?.

Compare the right type of cover

Decreasing cover often costs less than equivalent level cover because the insurer’s potential payout reduces. But a repayment mortgage and a decreasing life policy don’t necessarily shrink at exactly the same rate. Check the assumed interest rate and whether you’d still have enough cover if your mortgage arrangements change.

Our level versus decreasing life insurance comparison looks at that choice in more detail.

Make sure you’re comparing like with like

If one quote is for £250,000 of level cover over 25 years and the other is for £250,000 of decreasing cover, they aren’t equivalent policies. You could pay less for the second one and receive a much smaller payout later in the term.

Before comparing prices, put these details side by side:

• Amount insured: is the payout fixed, increasing or decreasing?
• Policy term: will it still be in force when your family needs it?
• Premium basis: is the premium guaranteed for the term or can it be reviewed?
• Who is insured: one person, or a joint policy that may end after the first claim?
• Additional benefits: what is included and what costs extra?
• Underwriting: is the premium confirmed, or could it change after the insurer assesses the application?

It’s a fairly ordinary checklist. That’s the point. You want to spot a meaningful difference before you sign, not when somebody needs to claim.

Read the bits most people skip

Terminal illness benefit

Many term life policies offer an early payment in certain terminal illness circumstances. The definition, evidence required and restrictions — especially near the end of the policy — vary. An early payment can reduce or use up the life cover rather than being a completely separate payout.

Premium reviews and increases

A guaranteed premium offers more certainty, provided you don’t change the policy. Reviewable premiums can be adjusted according to the terms. An increasing-cover policy might also raise what you pay over time. Ask for a clear explanation of when and why payments could change.

Keeping or changing cover later

Changing jobs, moving house or having another child can change the amount of cover you need. Some insurers offer useful options for changing cover after certain life events, but the limits differ. Don’t assume you can add extra cover without fresh underwriting.

When cover starts

Getting an online estimate isn’t the same as having life insurance in force. Cover generally starts only when the insurer accepts the application on its terms and the policy’s commencement requirements are met. Check the confirmation carefully, especially if you need cover before a house purchase completes.

Would two single policies be better than one joint policy?

This is worth asking before assuming a joint policy is the obvious choice for a couple.

A typical joint first-death policy pays once and then ends. Two single-life policies may cost more or less depending on the circumstances, but can provide a separate insured benefit for each person. That can matter if one partner dies and the other still has dependants to support.

Neither arrangement is automatically better. Compare the cost, the benefit each person needs and what happens after a claim.

Health questions can change the answer

Two insurers can assess the same application differently, particularly where there is a medical history, higher BMI, nicotine use or a hazardous occupation. The lowest initial figure isn’t necessarily the one you’ll be offered once underwriting is complete.

Be accurate about your medical history and answer the questions asked. If an insurer needs a GP report or further evidence, that doesn’t itself mean an application will be declined. It means they need information to assess it.

If you’ve previously struggled to get cover, our life insurance and medical conditions guide covers the main issues.

What about life insurance with critical illness cover?

Life insurance is designed to pay on a valid death claim, or earlier if a covered terminal illness provision applies. Critical illness insurance is different: it can pay if you meet the policy’s definition of a specified serious illness.

Adding critical illness cover can change both the premium and what happens after a claim. Check whether the benefits are separate or whether one payout ends the combined cover. More listed conditions don’t necessarily mean a better policy; the actual definitions are important.

How to compare life insurance quotes without wasting time

I’d keep the process fairly simple:

1. Write down who needs the money and what it would have to cover.
2. Work out the amount of cover and how long it’s needed.
3. Decide which policy type matches that need.
4. Compare quotations using the same amount, duration and relevant features.
5. Check the policy wording and any terms the insurer applies after underwriting.

A comparison website can be a useful first look at prices. An insurer can explain its own products. A broker can help you consider options from the insurers on its panel and, where advice is provided, the reasons for a recommendation. Those are different services, so check what kind of help you’re actually getting.

Before you apply

There’s no need to know the answers to every insurance question before getting in touch. If you’re unsure whether you need one policy or two, or whether level or decreasing cover makes sense, explain what you’re trying to protect.
