Your home insurance price explained

How we calculate the premium you pay

How insurance works

To work out the price of your insurance, we weigh up several factors. Some factors are specific to you, including the chances of you making a claim. Other factors are to do with the world around you and what’s happening in the insurance market. 

Every customer pays into a central pot, and if you make a claim we pay it out of that pot. If lots of people claim at once, the pot has to go further, which means prices go up. But whatever happens, we constantly review the way we calculate the cost of home insurance so we can make sure we offer you the most accurate price.

On this page, we’ve explained these factors and how they affect your price.

Your home insurance renewal

Before your current policy comes to an end, we’ll send you a renewal invitation. It will show two prices – last year’s price and a price for continuing cover for another year.

As you’re already a customer with us, your price to renew your cover will be the same as or lower than the equivalent price for a new customer. Your price might be quite different this year because of recent changes in regulation which affect all insurance providers.

If the specific cover you have with us isn’t available to new customers any more, we’ll compare your renewal price against the new customer price of the policy which most closely matches yours.

How you affect your price

Where you live

Public data on your property’s local area is used to rate your address and set your personal price. Factors include the average claims cost and future claims we expect in your neighbourhood. If claims in your area go up it may cost more to insure your home.

Any past claims

To work out your price, we factor in your claims’ history, which includes any accidents, claims, or losses in the last 5 years. The fewer the past claims you have, the lower you can expect your premium to be.

Your home’s build

How your property is built is likely to affect your price. Based on greater risk of fire-damage, wooden features, such as timber frames, may raise your premium. Any non-standard building materials that may cost more to source or repair will have the same effect.

How events affect your price

Severe weather

Long cold or wet spells can burst pipes and damage homes. Plus, we regularly review the chances of flooding driving up future claims. The Government works with insurers, including Aviva, to make sure residents in flood areas can get their homes insured. This has driven the Flood Re initiative.

Rising repair costs

From TVs to tablets, state-of-the-art kitchens to lighting, the items in your home get ever dearer. Naturally, it’s also getting dearer to fix them, which increases the cost of providing insurance and the price you pay.

Changing claims market

If the variety of claims we receive changes, so to do our prices. We estimate how much we’re likely to pay in future claims, and factor this cost into your premium. Escape of water claims make up a large part, costing an average £2,900 in 2016.

Number of claims

Rises in claims can drive up prices. In 2016 we paid out £2.7 billion to over 775,000 UK customers. That's on 96% of claims across motor, home, travel, protection and health. As of 1 December 2019, and shown on our website, claims ratings and reviews by customers buying or claiming on our home insurance averaged 4.5 out of 5.

Insurance Premium Tax increase

Each price includes Insurance Premium Tax (IPT). In 2016 the Government announced a rise in IPT from 9.5% to 10%, so all prices went up accordingly. A further IPT increase to 12% was implemented in June 2017.

Other costs

You can access our products in different ways. Your premium includes costs for current services, such as contact centres and online support, and for investing in future products and services.
