Business Insurance | Would Your Claim Be Paid in Full?

Business insurance

When was the last time you checked your business insurance ?

Close to three in four UK SMEs carry some underinsurance. Where a sum insured has fallen behind what it would cost to rebuild or replace, the insurer can cut a claim by the same proportion. Cover is worth going through at every renewal, and every two years at the very least.

What a shortfall takes off a claim

The sum insured shown on your schedule for buildings, stock, contents or plant.

Rebuild or replacement cost at today's prices, not what you paid or the market value.

A loss does not have to be total for a shortfall to bite. Partial claims are scaled down the same way.

This shows how an average clause works. Whether one applies to you, and how it is worded, depends on your own policy. A claim is also capped at the sum insured.

Two ways a payout gets cut

The first is underinsurance. Many commercial property and contents policies carry an average clause, which applies where the sum insured is below the value at risk. It scales the settlement down to the proportion you had insured, on partial losses as well as total ones.

The second is what you told the insurer. The Insurance Act 2015 sets a duty of fair presentation. Where something material was not disclosed and the insurer would have charged a higher premium, it can pay a proportion of the claim instead of the whole of it. On a premium of 2,000 pounds against the 2,500 pounds the insurer would have charged, that proportion is 80%, and a 50,000 pound claim is settled at 40,000 pounds.

Aviva reports that 68% of brokers have seen a rise in claims being declined or settled for less than the amount claimed. Our guide to reviewing your business insurance every year sets out what to look at before renewal.

What you find yourself

£15,000

Worked example using an average clause. A building insured for 120,000 pounds against a rebuild cost of 180,000 pounds is insured for 67% of its value, so a 45,000 pound claim is settled at 30,000 pounds. The rest comes out of your own money, which is one of the reasons a small business keeps a cash reserve.

What the check covers

The business you insured at the last renewal is not always the business you are running now. Our guide sets out what to go through before a renewal.

Sums insured

Buildings, stock, contents and plant against what they would cost to rebuild or replace at today's prices.

What the insurer was told

New work, new premises, new equipment and anything else that counts as a material circumstance under the 2015 Act.

Cover you do not hold

Employers liability, business interruption and cyber are the three most often missing or set too low.

Legal duties

Employers liability must be at least 5 million pounds with an authorised insurer. GOV.UK sets a fine of 2,500 pounds for every day you are not insured.

Frequently asked questions

What does underinsurance do to a claim?

Where a policy carries an average clause and the sum insured is below the true value, the insurer can reduce what it pays by the same proportion. A property insured for two thirds of its rebuild cost can have a claim settled at two thirds, whatever the size of the loss.

What is an average clause?

It is a condition in many commercial property and contents policies that applies where the sum insured is lower than the value at risk. It scales the settlement down to the proportion of the true value you had insured. Whether one applies to you depends on your own policy wording.

How much employers liability cover do I need by law?

GOV.UK states that employers liability insurance must cover at least 5 million pounds and must be held with an authorised insurer. You can be fined 2,500 pounds for every day you are not insured, and 1,000 pounds if you do not display or produce the certificate when asked.

What do I have to tell the insurer?

The Insurance Act 2015 sets a duty of fair presentation. You must disclose every material circumstance you know or ought to know after a reasonable search. If you do not and the insurer would have charged a higher premium, it can settle a claim proportionately rather than in full.

How often should I check my cover?

At every renewal, and every two years at the very least. Check again whenever something changes. Taking on staff, moving premises, buying plant, adding a vehicle, starting to hold customer data or taking on work of a different kind can all change what you need and what you must disclose.

Does the check cost anything?

No. The check is free and there is no obligation to change anything. It is carried out by a broker, not by IQ Money.

Who carries out the check?

A broker regulated by the Financial Conduct Authority. IQ Money publishes this page and does not advise on insurance, arrange cover or carry out the check.
