It sounds like a huge amount. But that’s what can happen if you have a leak inside your loo, trickling down the back of the bowl.
It’s an easy leak to miss – but one in eight homes has a leaky loo, so they’re really common.
With leaky loos losing up to 400 litres of tap-quality water a day – the same as filling five bath tubs – not many people realise how much they can add to your bill. Luckily, the answer’s simple. All you need to do is give your loos a quick check once a month. And if you do find a sneaky leak, they’re usually easy to fix.
Only 5% of customers think a leaky loo can waste at least 250 litres every day**
1st of the month – check your loosIf you’ve got more than one loo, it’s not unusual to have more than one leak – and dual flush toilets are the worst culprits. A leak can start out of the blue and be hard to spot, which is why a monthly check is such a good idea.
But if you do find a leaky loo at home, don’t worry. The good news is, research shows people in Cambridgeshire often fix their own. Or it’s usually a quick job for a plumber. Can we check our loos every month, to stop wasting money and help protect local chalk streams? Yes We Cam!

Doing our bit for local chalk streams
By checking your loos once a month and fixing any leaks, you’ll be helping protect Cambridgeshire’s chalk streams – a habitat as unique as the Amazonian rainforest or Great Barrier Reef.
All of the water we pipe into your home is high-quality drinking water – including the water in your loos. It’s supplied by aquifers, the same groundwater sources that supply our chalk streams.
But climate change and modern water usage are combining to make Greater Cambridge seriously water stressed†. So anything that helps waste less water is great news all round.
