5 unfortunate events your home insurance might not cover

You can always rely on home insurance to be there when things go wrong. Except when you can't.

From unruly dogs to stolen lawnmowers, there are times your home insurance policy might be less useful than you'd hope.

Many policies won't pay out for certain types of damage or loss, but if you haven't read the small print, you won't know until it's too late.

Luckily, we've gone through all the small print of 59 contents and 59 buildings policies, to save you the trouble.

Here, we look at five things you might not be able to claim for on your home insurance without switching to a more comprehensive policy.

1. Domestic pet damage

Torn up carpets and sofas will be familiar sights for many dog and cat owners. But home insurance doesn't always cover replacing them.

When we analysed 59 contents insurance policies, only one in seven (14%) covered pet damage as standard. Eight in 10 (78%) didn't cover it at all and one in 10 (8%) offered it as an optional extra.

2. Accidental damage

With everyone spending a lot more time at home at the moment, we could be more likely to accidentally break glasses, chairs or - God forbid - TV remotes. We may even have caused damage to parts of the house itself, like walls or flooring, by accident.

But home insurance cover for breaking parts of your house - or the things in it - is sometimes optional. Without it, you'll have to pay the full costs of repairing or replacing whatever you break.

When it comes to buildings insurance policies, only three in 10 (29%) included full accidental damage cover as standard, and the same number offered it at an extra cost. The majority of buildings insurance policies, though, provided some accidental damage cover as standard, with full cover available as an extra.

As for damage to contents in your home, just two in 10 covered it as standard, while four in 10 (42%) offered it as an extra and a quarter provided partial cover with more available at an additional cost.

3. Matching sets

Breaking or losing one piece of a matching set of crockery can be infuriating. Luckily, some insurers will find a matching replacement for the damaged individual item, or even replace the whole set. This way you won't end up with mismatched plates, for example.

But before you lodge a claim for that cracked china bowl, you'll need to check your policy. Because less than half (47%) of the 59 policies we analysed included matching sets cover.

4. Garden cover

Plants, toys and garden furniture are not cheap, so it's important to make sure your home insurance policy covers your backyard. Especially if you have a big ticket item like a trampoline or hot tub out there.

Thankfully, most home insurance policies do cover the items in your garden, but one in five of the policies we analysed either didn't, or only had garden cover as an optional extra. So there is still a chance your prized petunias could be at risk.

5. Theft from outbuildings

The combined cost of your shed's contents adds up quickly: lawnmowers, bikes, furniture.

The majority of home insurance policies we analysed do cover items stolen from your shed, but for one in 10 policies they were either not covered or only covered as an add-on.
