Is it worth claiming on home insurance for water damage?
It depends on the size of the damage weighed against your excess and the likely effect on your premium and no-claims discount. Small damage close to your excess amount is often not worth claiming, but larger escape-of-water claims usually are. Get a rough repair cost first, then compare.
Do a quick sum before you pick up the phone. Get a rough idea of the repair cost, then compare it against your excess, the fixed amount you pay towards any claim. If the damage costs £600 to fix and your excess is £500, you recover around £100, which may not be worth the downsides.
Those downsides are the effect on future premiums and, on some policies, your no-claims discount, the reduction insurers give for claim-free years. A claim can push up what you pay at renewal and stays on your record, since insurers share claims data. A small claim can cost you more over a few years than it returns.
Larger damage changes the sum. A serious escape of water, say a burst pipe or a failed washing machine that soaks floors, ceilings and kitchen units, runs into thousands or tens of thousands of pounds. That is what home insurance is for, and paying it yourself to protect your premium costs you more than it saves.
We won't tell you not to claim. It's your decision and your policy. Weigh the real repair cost against the excess and the likely renewal impact instead of guessing. If you're unsure of the cost, get an assessment before you decide, because water damage is often worse behind walls and under floors than it first looks.
This is general information, not financial or policy-specific advice. Check your own policy wording for your excess and whether a claim affects any no-claims discount, and remember that a late report can itself cause problems.
A worked example
Numbers make the decision clearer than principles do. Take a failed washing machine hose that soaks a kitchen floor and the hallway beyond it.
Suppose the repair comes to £2,400 for flooring, skirting and redecoration, and the escape of water excess is £450. Claiming recovers £1,950. If the claim adds, say, £70 a year to the premium and the claim stays on record for five years, the lifetime cost is around £350. Claiming is clearly worth it.
Now change the repair to £700. You recover £250, against roughly £350 of future premium cost, and you have spent weeks on the process. That one is not worth claiming, and the sum tips well before the repair cost reaches the excess.
The rough rule that falls out of this: below about twice your excess, think hard. Above three or four times, the claim usually pays for itself.
Get a real figure before you decide
The weakness in every calculation above is the repair estimate, and water damage is the peril most likely to be worse than it looks.
Water tracks along joists and under floor coverings, wicks up plasterboard, and soaks insulation inside a wall cavity where nothing shows at the surface. A stain on a ceiling can mean one wet joist or a saturated floor void in the room above. Damage that appears to be a few hundred pounds of redecoration turns into a strip-out often enough that deciding not to claim on a first impression is a real risk.
Get a builder or a damage restoration firm to look properly before you decide, and ask them what they would expect to find once the floor comes up. If the honest answer is that nobody knows without opening it, that uncertainty is itself a reason to put the claim in.
When to claim regardless of the arithmetic
Some situations override the sum entirely.
- Another property is involved, in either direction, because liability may be argued later and you want it on record now.
- The property is or may become uninhabitable, since accommodation costs dwarf most repair bills.
- The water reached electrics, or has been sitting long enough that structural timbers may be affected.
- The source is hidden and detection costs are likely, which is what trace and access cover exists for.
- The water was contaminated, from drainage or sewage, where the requirement is sanitising rather than drying.
- You cannot fund the repair yourself, which is the reason the policy exists.
If you decide not to claim
Choosing to pay for the repair yourself is a reasonable decision, but it needs finishing properly rather than quietly dropping.
Have the cause fixed and get it in writing, and make sure the property is dried before anything is made good. A repair laid over a damp substrate produces a second, larger problem, and one you have already decided not to claim for.
Keep the paperwork: the plumber's report, the invoices and photographs of the damage and the repair. If a related problem emerges later and you do claim, that file is what shows the earlier incident was dealt with properly rather than left. It also protects you against the argument that new damage is the unrepaired consequence of an old leak.
Answer renewal questions accurately. Insurers often ask about damage or incidents rather than only about claims, and an unclaimed escape of water may still need declaring depending on how the question is put.
