Do I need plumbing and drainage cover?

Picture this: a pipe bursts under your floorboards, or your drain backs up into the garden. You reach for your insurance policy, only to find it doesn't cover the repair. Standard buildings insurance rarely covers everything that can go wrong with your plumbing or drains, and that gap between what you assume is covered and what actually is can be an expensive surprise. Here's what plumbing and drainage cover actually includes, and how to decide if it's worth adding.

Plumbing and drainage cover explained
Standard buildings insurance may only cover some plumbing or drainage issues, which is why many homeowners add dedicated cover for sudden or accidental damage. Typical inclusions:
Seized taps
Sewer backup
A clogged water supply
Leaking or burst pipes
Blocked or leaking drains
Blocked or overflowing sinks and toilets
Depending on the policy, cover can extend to external drains like blocked sewer lines too.
Typical exclusions:
Non-urgent issues
Blocked guttering
Electric showers
General wear and tear
Plumbing problems caused by faulty installation or previous repairs
Shared or public drains that aren't your responsibility
Check the coverage limit on any policy you're considering, so an emergency repair doesn't exceed what you're actually covered for.
Emergency plumbing and drainage cover
Plumbing and drainage cover (sometimes bundled into wider home emergency cover) is specifically useful for major leaks or severe blockages that risk water damage to your home. Always check what your specific provider defines as an emergency before assuming you're covered.
Most insurers consider an emergency to be something that:
Causes permanent damage to your home
Leaves your home unsafe or exposed to intruders
Poses a risk to your household's health or wellbeing

FAQs
Building insurance generally covers sudden, unexpected water damage ("escape of water"), but not all situations, and rarely the cost of repairing the pipes themselves. Check your policy's specific terms to see if extra cover makes sense.
Usually the homeowner. If you rent, it's your landlord or property manager's responsibility. Your water company may be responsible if the cause is an external drain or sewer issue.
It depends on location: your water company typically handles blockages in the public sewer line, while blockages within your property up to that point are your responsibility.
It depends on how severe the blockage is. Our guides to drain unblocking, drain repair, and plumbing inspection costs give current pricing for rodding, jetting, and CCTV surveys.
Look first for the cause: slow drainage or bad smells are common signs. You can try a heavy plunger for minor blockages, a drain rod for anything further down, or a high-pressure jet wash for stuck debris. If none of these work, call a professional plumber or drain specialist; your insurer, if you have cover, can help arrange and pay for this.
