Accidental damage accounts for roughly one in four home insurance claims in the UK, yet most standard policies don’t cover it unless you specifically add it. That means a spilled glass of wine on a new carpet, a child’s foot through a plasterboard wall, or a television knocked off its stand can leave you paying the full repair bill out of pocket. With the average home insurance claim now sitting at around £6,340, according to 2025 claims data, the question of whether to pay extra for accidental damage cover is really about how much financial risk you can absorb yourself.

Those figures tell a clear story. Accidents happen often, and when they do, the cost of putting things right has climbed sharply. But accidental damage cover is an optional add-on, not a given. Some insurers include a basic level — usually fixed glass and sanitaryware — as standard, while full cover costs extra. The difference between what you already have and what you’d pay to upgrade can be surprisingly small, or surprisingly large, depending on your provider and your home. Here’s what you actually need to know.
The Association of British Insurers defines accidental damage as sudden and unintentional physical damage caused by an outside, visible event. That definition matters because it draws a hard line between a genuine accident and something that develops over time. A paintbrush dropped on a carpet counts. A carpet that has worn thin after ten years does not. What I tend to notice is that people assume accidental damage cover is broader than it actually is — the exclusions often matter more than the inclusions.
What Accidental Damage Cover Actually Costs — and When It Pays Off
The price of adding accidental damage varies by insurer, property, and whether you cover buildings, contents, or both. Most providers split the cover into two separate add-ons, letting you choose one or the other. The table below shows typical costs and limits based on current market data.

| Cover Type | Typical Annual Cost | Single Item Limit | Standard Excess |
|---|---|---|---|
| Buildings accidental damage | £20 – £30 | £2,000 – £5,000 | £100 – £250 |
| Contents accidental damage | £15 – £20 | £1,000 – £2,000 | £100 – £250 |
| Combined (buildings + contents) | £35 – £75 | Varies by item | £100 – £250 |
Single-item limits matter more than most people realise. If your television costs £1,500 and your contents accidental damage limit is £1,000, you’re £500 short unless you specify the item separately. Higher-value items need to be listed on the schedule to be covered for their full replacement cost.
Repair costs have risen 126% since 2020, which makes any single accident more expensive than it used to be. Replacing a large-screen television can cost nearly £2,000. Drilling through a concealed water pipe during DIY can run into thousands. The financial case for the add-on hinges on whether your household is likely to need it within a reasonable timeframe.
One note on the numbers: different sources report slightly different claim proportions. UtterlyCovered puts accidental damage at 25.44% of all home insurance claims, while MoneyHelpDesk cites roughly 19%. The variation probably reflects different claim categorisation methods, but both confirm that accidental damage is the single most common reason people claim on home insurance in the UK.
Errors and Gaps That Cost Homeowners Money
Assuming accidental damage is already included
Most standard home insurance policies do not include full accidental damage cover. They typically cover a limited set of items — fixed glass in windows and doors, ceramic hobs, and sanitaryware — but not the rest of the structure or your belongings. If you haven’t explicitly added accidental damage to your policy, a spilled drink on a sofa or a cracked laptop screen is your cost to bear. The fix is straightforward: check your policy schedule or call your insurer to confirm what you have. If you only have basic cover, you can usually add full accidental damage at any point, though some insurers restrict this to renewal.
Ignoring single-item limits
Contents accidental damage policies almost always cap how much they’ll pay for any single item. Typical limits range from £1,000 to £2,000, which may not cover a high-end television, laptop, or musical instrument. If you own items worth more than the limit, they need to be listed individually on the policy schedule. What I’d do is take a quick inventory of anything worth over £1,000 and check whether your policy’s single-item limit would leave you underinsured. Naming them costs a bit more but avoids a nasty surprise at claim time.
Believing pet damage is covered
Pet damage — chewing, scratching, tearing, fouling — is a standard exclusion on virtually all accidental damage policies. A dog that chews through a sofa or a cat that scratches a leather chair will not be covered, even if you have full accidental damage on your contents. Some specialist insurers offer separate pet damage products, but the standard home insurance add-on does not include it. If your pet is likely to cause damage, factor that cost into your decision rather than assuming the policy will handle it.
Overlooking the excess when making small claims
Your policy excess applies to accidental damage claims just like any other claim. If your excess is £200 and the repair costs £180, you get nothing from the insurer and you’ve still reported a claim — which can push up your premium at renewal. The average accidental damage claim is large enough to exceed the excess in most cases, but small, frequent claims can leave you worse off. A good rule of thumb is to claim only when the damage clearly exceeds your excess plus the likely premium increase at renewal.
How to Decide Whether Accidental Damage Cover Is Right for Your Home
Assess your household’s actual accident risk
The strongest predictor of whether you’ll use accidental damage cover is your household composition. Families with young children typically claim once every two to three years for damage to carpets, walls, or electronics. Households with pets claim at similar frequency, though pet damage itself is excluded — it’s the other accidents that add up. Homes with adult occupants, no children, and no pets see far fewer claim events. What I’d do is look back at the last five years and count how many accidents cost more than your policy excess to fix. If the answer is two or more, the add-on probably pays for itself.
Check what your existing policy already covers
Before paying for an upgrade, find out what your current policy includes as standard. Many insurers include limited accidental damage for specified items — fixed glass, ceramic hobs, sanitaryware, and sometimes underground services. Some premium-tier policies from providers like Aviva, AXA, and LV= include full accidental damage as standard rather than as an add-on. Reading the policy wording or calling your insurer to clarify what “standard cover” actually means can save you paying for something you already have. For a deeper look at what standard policies often leave out, the article on hidden property insurance exclusions is worth a read.
Compare the add-on cost against the cost of self-insuring
Self-insuring means setting aside the money you would have spent on the add-on premium each year and using it to pay for accidents yourself. On a typical policy, that’s £50–£75 a year. Over five years, you’d have £250–£375 saved. If you have one accident in that period costing £400, you’re slightly behind. If you have none, you’re ahead. The breakeven point is roughly one claim every three to four years. For households with a low accident rate, self-insuring is often the cheaper option. For busy homes where accidents are a regular occurrence, the add-on provides better value.
Emerging trends in 2026: modular policies and rising repair costs
Insurance products are becoming more modular, with accidental damage increasingly treated as a separate, optional component rather than bundled into standard cover. Some insurers now offer tailored add-ons for specific risks — DIY accidents, pet damage, or cover for home office equipment. Repair cost inflation continues to push up the average claim value, which makes the add-on more valuable in absolute terms but also means insurers are raising premiums to match. The average combined home insurance premium in Q1 2026 was approximately £375, according to ABI data, and that figure is likely to rise further as construction costs climb. Reviewing your cover at each renewal is the only way to keep pace with what the market is doing.

The Real Question Is Your Household’s Accident Rate
Accidental damage cover is not a one-size-fits-all product. It works well for homes where accidents are a regular fact of life — young children, pets, frequent DIY, expensive electronics. For quieter households, the annual premium is usually better spent building your own emergency fund. The key is knowing what your current policy already covers, what the add-on actually includes, and how often you realistically expect to use it. Repair costs are rising, so the financial stakes of a single accident are higher than they were five years ago. But that doesn’t automatically make the add-on worth it for everyone.
