Should I get accidental damage home insurance is a question most UK households consider at renewal. The honest answer depends on the people, the pets and the possessions in the home. Accidental damage cover steps in when an everyday mistake causes damage that the standard policy does not pay for, from spilt paint to a fork through the laundry to a smashed television. Premiums typically rise 20 to 30 per cent when the add-on is included, which sets the bar for how often a household would need to claim before the add-on pays for itself. Understanding what the cover does and does not include is the starting point.
Should I get accidental damage home insurance?
Accidental damage home insurance is an add-on extension to a standard buildings and contents policy. The Association of British Insurers defines accidental damage as sudden and unintentional physical damage caused by an outside, visible event. The classic examples are a paintbrush dropped on a carpet, a glass of red wine across a sofa, a child putting a foot through a plasterboard wall, or a vacuum cleaner cable through a door. None of these is a covered event under the standard insured perils, which is why insurers package accidental damage as a separately rated extension.
Households where small accidents are common see the highest claim frequency on the add-on. Families with young children, pet owners and households with valuable electronics or musical instruments are the typical buyer profile. The add-on is also popular with first-time buyers who have invested in fitted carpets, polished wood floors and new appliances and want the broadest cover available against everyday damage.
The decision is largely a financial one. If the typical accidental damage claim would cost less than the additional premium each year, the policyholder is better off self-insuring. For households where a single significant claim every few years is realistic, the cover pays for itself over time. Comparing the additional premium against the cost of replacing one big-ticket item from cash gives a quick decision.
What accidental damage cover home insurance includes
Full accidental damage cover splits into two parts. Buildings accidental damage covers sudden damage to the structure of the home, including walls, ceilings, floors, fitted kitchens, sanitaryware and conservatories. A foot through a ceiling from the loft, a hammer through a wall during DIY, or a saucepan dropped on a bathroom basin would all fall within buildings accidental damage. Insurers settle these claims as part of the buildings element subject to the policy excess.
Contents accidental damage covers sudden damage to belongings inside the home. The most commonly claimed items are televisions, gaming consoles, sofas, dining tables and carpets. The cover pays for repair or replacement on a like-for-like basis up to the contents sum insured, with the standard single article limit applying unless the item is specified on the schedule. Some insurers offer accidental damage to a defined list of items rather than full cover, so reading the policy summary matters.
Most policies include a baseline level of buildings accidental damage even without the add-on. The baseline usually covers fixed glass in windows and doors, fixed sanitaryware and underground services. This is why some insurers describe the add-on as full accidental damage and the standard wording as limited accidental damage. Knowing what is already included narrows the question to whether the additional cover on contents and the rest of the structure is worth the premium.
What accidental damage cover does not include
Wear and tear is excluded even with accidental damage cover in place. A sofa worn through over many years is not an accident. A carpet that has thinned with use is not a covered claim. Insurers maintain this exclusion across every wording because accidents are by definition sudden and unintentional. Damage that has developed gradually is treated as maintenance and falls outside the scope of cover.
Mechanical and electrical breakdown is also excluded. A television that simply stops working is a manufacturing or component failure rather than an accident. Some policies offer separate domestic appliance cover or extended warranty products that respond to breakdown, but the home insurance accidental damage add-on does not. The distinction can be confusing for households expecting a single answer to all damage to electronics.
Pet damage exclusions appear in most contents accidental damage wordings. Scratches caused by cats, chewing by dogs, and similar damage caused by domestic animals are usually excluded. Some specialist pet damage products plug the gap. Reading the exclusions list on the policy wording is the safest way to understand what the cover does and does not extend to before relying on it.
Accidental damage cover cost and the breakeven calculation
Adding full accidental damage to a standard combined home insurance policy usually increases the premium by 20 to 30 per cent. For a baseline policy at £250 a year, the add-on costs roughly £50 to £75 annually. The breakeven point against a single claim depends on the household excess and the value of the damaged item. A typical household excess of £150 plus a £75 premium uplift means the policyholder is paying £225 in the first year to be £225 out of pocket on the first claim.
This is why the add-on tends to pay off over multiple years rather than within a single year. Households that make a claim every three to four years usually break even or come out ahead. Households that go a decade without a claim tend to overpay. Past claims experience is a useful indicator of likely future use, although life events such as having children or moving to a new home can change the risk profile suddenly.
Pricing comparisons across UK insurers vary widely. Some insurers price accidental damage as a single combined add-on, while others split it between buildings and contents and price each separately. A small premium difference between two insurers can disappear once the add-on is included. Comparing on a like-for-like basis with the same accidental damage assumption is the only way to make a fair comparison.
Whether accidental damage cover home insurance is worth it
Whether accidental damage cover is worth it depends on the household. Families with young children typically claim at least once every two to three years for damage to carpets, walls or electronics. Households with pets often claim for similar damage caused by chewing or scratching. Larger families and busier homes have more potential claim events. For these households the add-on usually pays for itself across a renewal cycle.
Households with adult occupants, no pets and modest contents see far fewer claim events. The add-on usually does not pay for itself in such a profile, and the policyholder is paying for cover that is unlikely to be used. Where a one-off significant claim does occur, the cost of self-paying for the repair may still be lower than the cumulative cost of the add-on over many years.
The Financial Conduct Authority requires insurers to make the cover terms clear at sale and to allow cancellation within the 14 day cooling off period under Insurance Conduct of Business rules. Policyholders who realise the cover is not needed can cancel and receive a pro-rata refund subject to any minimum premium. Renewals are the natural point to review whether the add-on still makes sense, and most insurers allow the add-on to be removed at renewal without restarting the main policy.

Frequently asked questions
What is accidental damage home insurance?
Accidental damage home insurance is an add-on that covers sudden, unintentional damage to the home or contents that is not part of the standard insured perils. Examples include spilt drinks on carpets, a foot through plasterboard, or a television knocked off a stand. Cover is split between buildings accidental damage and contents accidental damage on most policies.
Should I get accidental damage cover on my home insurance?
The cover is generally worth the cost for households with young children, pets or valuable electronics who claim once every two to three years on average. For homes with adult occupants, no pets and modest contents, the additional premium rarely pays for itself. Comparing the annual uplift against the likely claim frequency is the practical test.
How much does accidental damage cover cost on home insurance?
Full accidental damage typically adds 20 to 30 per cent to the underlying home insurance premium. On a baseline policy of £250 a year, the add-on costs around £50 to £75 annually. Some insurers split the cover between buildings and contents and price each separately, which allows policyholders to take only the part they need.
What is not covered by accidental damage insurance?
Wear and tear, gradual deterioration, mechanical and electrical breakdown, and most pet damage are excluded even with the add-on in place. Some policies exclude damage caused by children below a defined age, or damage from DIY projects without proper precautions. The exclusions list on the policy wording is the definitive source for what is excluded.
Does home insurance cover dropped phones?
Standard contents insurance does not cover phones dropped at home unless the policy includes accidental damage on contents. With the add-on in place, a cracked screen from a household drop is a covered event subject to the policy excess and single article limit. Phones lost or damaged away from home need personal possessions cover as well.
Is accidental damage cover the same as no fault cover?
No. Accidental damage covers sudden, unintentional damage caused by the policyholder or household. No fault cover, more common in motor insurance, refers to damage caused by a third party. Home insurance accidental damage responds whether or not the policyholder is at fault, provided the event was sudden and unintentional and falls within the policy wording.
