What does home insurance actually cover?

Home insurance is something most people arrange because they have to, either as a condition of their mortgage or simply as a sensible precaution, without always knowing exactly what they are paying for. The details tend to get skim read at the point of purchase and forgotten shortly after. That is understandable, but it can lead to surprises at the worst possible moment. This guide explains what home insurance is designed to do, what to look for when reviewing a policy, and the questions worth asking before you assume you are covered.

The two main types of home insurance

Home insurance is not a single product. It is generally made up of two distinct types of cover, which can be bought separately or together as a combined policy.

Buildings insurance is designed to cover the structure of your home, which typically means the walls, roof, floors, windows, and fitted fixtures. If your home is damaged by an insured event, buildings insurance is the cover intended to pay for repairs or, in serious cases, rebuilding. If you have a mortgage, your lender will usually require you to have buildings insurance in place as a condition of the loan, though it is always worth confirming the specific requirements with your lender directly.

Contents insurance is designed to cover the belongings inside your home, such as furniture, clothing, electronics, and personal possessions. If items are stolen, damaged, or destroyed by an insured event, a contents policy may pay to replace or repair them. Unlike buildings insurance, contents cover is not usually a mortgage requirement, though what it covers and to what value varies considerably between policies.

Many insurers offer combined buildings and contents policies. Whether a combined policy or two separate ones makes more sense will depend on your circumstances and what is available at the time.

What to look for in a buildings policy

Buildings insurance policies are generally structured around a list of events they will and will not cover, sometimes referred to as insured perils. These vary between insurers and products, so it is important to read the policy documents carefully rather than assuming a standard set of events applies.

Events that policies may cover can include fire and smoke damage, flooding, escape of water from burst pipes, storm damage, subsidence, and impact from vehicles or falling objects. However, the precise wording of what is and is not included differs from one policy to the next, and some events may be covered only under certain conditions or with specific add-ons.

One of the most important figures to get right in a buildings policy is the sum insured, which should reflect the rebuild cost of your property rather than its market value. These two figures can differ considerably. The rebuild cost is what it would cost to demolish and reconstruct the property from the ground up using current labour and materials, without the value of the land. Most insurers provide guidance on calculating this figure, and independent tools are available to help. If the sum insured does not reflect the true rebuild cost, you may find that any payout in the event of a claim is affected.

What to look for in a contents policy

Contents policies also vary in their scope and the limits they apply, so it is worth reviewing the detail rather than relying on the headline cover level. Some policies replace items on a new-for-old basis, meaning they pay for a like-for-like replacement regardless of the age of the original item. Others use an indemnity basis, which takes depreciation and wear into account. The difference can be significant if you need to make a claim, so it is worth checking which basis your policy uses.

High-value items such as jewellery, watches, bicycles, or specialist equipment are often subject to individual item limits within a standard policy. If the value of any single item exceeds that limit, it may need to be listed separately on the policy and may attract an additional premium. Checking these limits carefully before you buy, rather than at the point of a claim, is sensible.

Accidental damage cover and personal possessions cover outside the home are not always included as standard. Whether your policy includes these, and under what conditions, is worth confirming directly with your insurer.

Questions worth asking about exclusions

Every policy will have exclusions, and these are often where the important differences between products lie. Rather than assuming a policy covers everything that is not explicitly mentioned, it is worth asking specific questions when you arrange or renew cover.

Some areas that are worth clarifying with your insurer include whether gradual deterioration or wear and tear is excluded, how the policy treats unoccupied properties and for how long, whether pest damage falls within or outside the scope of cover, and how accidental damage is defined and whether it requires an additional premium.

It is also worth asking how the policy handles situations where the sum insured turns out to be lower than the actual cost of a claim. Some policies apply what is known as the average clause in these circumstances, which can result in a proportionally reduced payout. Understanding how your policy handles this before you need to make a claim is considerably more useful than finding out afterwards.

Liability cover

Many home insurance policies include some form of personal liability cover, which may provide protection if someone is injured on your property or if you accidentally cause damage to a neighbouring property. The level of liability cover included varies between policies, and the conditions under which it applies can differ, so it is worth checking what your policy provides and whether it is adequate for your circumstances.

Frequently asked questions

Is home insurance a legal requirement? Home insurance is not required by law in the UK. However, if you have a mortgage, your lender will generally require buildings insurance as a condition of the loan. The specific requirements will be set out in your mortgage terms, so it is worth checking these directly with your lender rather than assuming a standard position applies.

How do I know if my buildings insurance covers flooding? Flood cover is not automatically included in every buildings policy, and cover can vary depending on the flood risk profile of your property. It is worth confirming with your insurer exactly what your policy includes in relation to flood damage, and checking the flood risk status of your property independently if you have any concerns. Your insurer or a broker can help clarify what is and is not covered under your specific policy.

What is the difference between rebuild cost and market value? Market value is what your home would sell for on the open market, including the land. Rebuild cost is what it would cost to reconstruct the building itself, without the land. For most properties these figures differ, sometimes considerably, and buildings insurance should generally be based on the rebuild cost. Using an inaccurate figure could affect any payout in the event of a claim, so it is worth taking care with this calculation.

Does home insurance cover boiler breakdown? Boiler breakdown and central heating failure are not typically covered under standard home insurance policies, though policy terms vary. Some insurers offer home emergency cover as a separate product or optional add-on. If this is something you want cover for, it is worth asking your insurer specifically whether it is included or available as an addition to your policy.

What should I do if I am unsure whether something is covered? The most reliable approach is to contact your insurer directly and ask before you assume cover exists. Policy documents can be detailed and the language is not always straightforward, so asking a specific question about a specific situation tends to give a clearer answer than trying to interpret the wording yourself. A broker can also help you understand the scope of your cover and identify any gaps.

Can I rely on the summary documents alone when reviewing a policy? Policy summaries give a useful overview but do not contain the full terms and conditions. The full policy wording sets out exactly what is and is not covered, including any conditions, limitations, and exclusions that apply. Reading the full documents before you commit, or asking an adviser to walk you through the key points, is generally a more reliable approach than relying on a summary alone.

Final note

Home insurance is one of those areas where the detail genuinely matters, and where policies can differ more than people often expect. Understanding what your cover is designed to do, checking the specific terms that apply to your policy, and asking questions when something is unclear will put you in a much better position than finding out what is and is not covered at the point of a claim. If you are unsure whether your current cover is appropriate for your circumstances, speaking to a qualified adviser is a sensible step.
