What is non-negligent liability cover?

Non-negligent liability cover is the part of a home insurance policy that can respond when damage happens without anyone being at fault. It sits alongside the liability cover that is typically included in standard home insurance, and it matters most in the everyday disputes that follow a storm, a leak or a falling branch: a fence blown down, a neighbour's wall cracked, a garden wall damaged by a vehicle nobody can trace.

The phrase describes a gap rather than a single product. Standard home insurance is usually made up of two main parts: cover for the building itself and cover for the contents within¹. Liability cover for injury or damage to other people or their property is typically included as standard, but it usually requires negligence, meaning someone failed to take reasonable care. Where nobody was negligent, a claim can fall between the two. Accidental damage cover, usually sold as an add-on, is the part of a policy most likely to respond to a sudden one-off event, but it excludes gradual deterioration, deliberate acts and defective workmanship².

What follows sets out what standard cover includes, the sudden-event rule that decides most claims, how an insurer settles, when a mortgage lender requires buildings insurance, and what cover costs.

What standard home insurance covers: buildings and contents

Home insurance, sometimes called household insurance, is usually made up of two main parts: cover for the building itself and cover for the contents within¹. Buildings cover deals with the structure, fixtures and fittings. Contents cover deals with the things you would take with you if you moved.

Several things that people assume are included are often sold separately. Personal possessions cover, comprehensive accidental damage cover and home emergency cover may not be included as standard⁶. Legal expenses cover is not the same as liability cover, which is typically included in standard home insurance⁶.

Where accidental damage is included, the scope varies. Hiscox includes accidental damage for buildings and contents as standard⁵. NFU Mutual includes some accidental damage cover as standard for glass and sanitary ware under buildings cover⁷. Nationwide's Essentials policy does not cover students' belongings or matching sets, meaning undamaged items in a suite or set if one part is damaged⁸.

The practical point is that two policies with the same headline price can differ sharply in what they will pay for. Checking whether accidental damage, personal possessions and home emergency cover are included, and at what limits, is part of comparing cover rather than price.

Sudden events only: wear and tear, groundwater and unoccupied homes

The dividing line in most disputes is whether the damage was sudden or gradual. Standard home insurance will not usually cover damage caused by wear and tear⁹. Damage caused by wear and tear or that happens slowly over time is not covered, including damp, condensation or rust¹⁰.

Accidental damage cover follows the same logic. Generally, accidental damage cover does not include damage caused by wear and tear, the gradual deterioration of something over time, wilful or deliberate acts, or defective workmanship². One insurer's list of exclusions covers accidents that happen while the property is unoccupied, deliberate destruction or vandalism, general wear and tear, cosmetic damage such as scratches and dents, poor design or workmanship, damage from construction, alteration or repair, and mechanical or electrical faults or breakdowns¹¹.

Other exclusions are specific to the peril. Groundwater flooding is often excluded⁹. Damage caused by pets, water entering the home, the home moving, settling or shrinking, and a paid maintenance worker or builder is excluded from one insurer's accidental damage cover¹². Contents accidental damage cover commonly excludes damage to contents while away from the home or garden unless contents away from home cover has been bought, damage when the home is empty, damage to money, damage to clocks from over-winding, and damage to items normally kept in the garden¹³.

How an insurer settles a claim: repair, replace or pay cash

When a claim is accepted, the insurer has three main routes: repairing the damage, replacing something lost or damaged, or paying cash to cover the cost of repair or replacement¹⁶. Policy wording often reserves the choice to the insurer. One example term reads:

That choice matters to the payout. If the customer insists on cash when the insurer is willing to repair or replace, the insurer will only pay the amount it would cost them, and because insurers get discounts from suppliers and contractors, that is usually less than market rates¹⁶. Where a cash settlement is offered for a gadget or phone, it is generally the cost of replacing the item with one of the same age and condition before the insured event, from a reputable source¹⁷.

If a claim is handled badly, the ombudsman can require remedies. Where a complaint is about a claim, it may ask the insurer to make necessary repairs, replace the item, offer a cash settlement, or compensate for distress or inconvenience¹⁷. Where liability was accepted unfairly, the ombudsman can tell the insurer to change the way the claim was recorded so the customer's current premium can be recalculated, refund extra money paid, and may award compensation for distress or inconvenience¹⁷.

When your mortgage lender requires buildings insurance

Home insurance is not a legal requirement². It becomes effectively compulsory through the mortgage. Most mortgage lenders will require you to hold buildings insurance². If you own your home, you will need buildings insurance, and it is usually a condition of your mortgage⁶. Mortgage lenders generally require it from the date of exchange³.

The timing catches first-time buyers out. Buildings insurance needs to be in place on the new home from the day contracts are exchanged, and most mortgage providers make this a condition of lending³. Lenders will require you to have arranged your home insurance and have it in place in time for contracts to be exchanged³. Unlike car insurance, it is not a legal requirement unless you have a mortgage lender, in which case it is usually an obligation of your mortgage contract¹⁸.

One related product is worth separating out. Mortgage indemnity insurance protects the lender, not you¹⁸. It is not the same as buildings insurance and does not cover your belongings or your liability to others.

What home insurance costs: an average of £383 a year

The average cost of a combined home insurance policy is £383 a year, according to Association of British Insurers figures for April to June 2026². That average hides wide regional and property-type variation.

The gap between Wales at £258 and Northern Ireland at £519 is £261, and both figures come from the same table². Pricing reflects where you live, when your home was built, previous claims, and the value of your contents¹⁹. One insurer charges a £14.99 arrangement fee, included in the agreed price for home insurance²⁰.

Underinsurance is the quiet risk behind a low premium. If the sum insured is below the true rebuild cost, a claim can be reduced. Reviewing buildings and contents cover at least once a year, perhaps at renewal, is the standard check⁵.

Why do long-standing customers pay more than new customers?

Rules protecting renewing customers from being charged more than if they were new do not stop your insurer offering you a cheaper price if you haggle². In other words, the protection sets a ceiling, not a floor, and the price you are offered at renewal is not necessarily the price the insurer will accept.

The ombudsman has published a case study of a customer who noticed after six years that her premium had increased considerably from when she first bought the policy, and decided to shop around²¹. That pattern is common enough to be worth planning for: the renewal quote is a starting point, and asking the insurer to requote, or checking the market, is a normal part of the process.

Are fences, gates and garden furniture covered?

Cover for the things outside the walls varies more than almost anything else in a home policy. Some policies include cover for garden furniture, trees, hedges, lawns and fences, while others do not⁶. Storm damage is covered, but fences, gates and outbuildings are often excluded³. Many policies do not cover damage to other parts of the property, such as patios, paths and terraces, unless the main residence is also affected²².

This is where non-negligent liability questions most often arise. A fence blown down in a storm, a gate damaged by a delivery van that did not stop, or a garden wall cracked by a neighbour's tree are all cases where fault may be unclear or absent. The answer usually turns on whether the policy includes the item at all, and whether the cause was a sudden event rather than gradual deterioration.

Will my insurer pay for somewhere to stay if my home cannot be lived in?

Policies generally include cover for temporary accommodation if your home has been made uninhabitable⁶. Home emergency cover may also provide alternative accommodation while the problem is being fixed if your home is unsafe or uninhabitable¹⁴. The two are not the same: home emergency cover responds to the emergency itself, while buildings or contents cover responds to the damage.

If you are evacuated as a precaution and your property has not been damaged, temporary accommodation is typically arranged through the local authority⁶. That distinction matters after a flood or a gas leak, when the property is intact but temporarily unsafe.

Travel insurance is a separate matter. While home insurance may cover certain possessions away from home, it will not cover medical care and cancellations²³.

Can I claim for damage if I did not have insurance in place?

If you do not have insurance, you will not be able to make a claim for damage to your property⁶. That is the straightforward answer, and it is why lenders insist on buildings cover.

There is a separate route where a product caused the damage. You can make a claim for negligence against either the manufacturer or the company you bought the item from, and you may have to prove they were negligent²⁴. For claims under £275, there is a small claims route²⁴.

The same principle runs through insurance disputes about fault. Most motor insurance policies have an exclusion saying people should take reasonable care to protect their vehicle from loss or damage, but if there is no evidence the customer recognised the risk, the ombudsman might say they have not been reckless and it is unfair to apply the exclusion²⁵. Fault, in other words, is assessed on what the person knew and could reasonably have done, not on the outcome alone.

How often should I review my home insurance cover?

It is usually a good idea to review your buildings and contents insurance cover at least once a year, perhaps when you renew⁵. Rebuild costs move with construction prices, contents accumulate, and home improvements change what needs insuring.

Underinsurance is the risk that review addresses. If the sum insured falls below the cost of rebuilding, a claim can be scaled back. Checking the rebuild figure and the contents total against current values is the practical step, and it is worth doing before renewal rather than after a loss.

Where to get help

If a claim is rejected or handled badly, the first step is the insurer's own complaints process. If that does not resolve it, the Financial Ombudsman Service can look at the complaint and, where it is upheld, require repairs, replacement, a cash settlement, or compensation for distress or inconvenience¹⁷. MoneyHelper offers free, impartial guidance on insurance and money questions, and debt advice charities can help where a loss has left bills unpaid.

Protection has limits. The Financial Services Compensation Scheme covers non-compulsory general insurance, including home insurance, at 90% of the claim⁴. That protects you if the insurer fails, not if the claim is declined. For disputes about what a policy covers, the ombudsman is the route.
