Don’t ignore the “surface water drainage” fee. This is a charge for rainwater runoff from your property, and it’s based on your home’s size and location. If you live in a flood-prone postcode, like a flat near a river, you pay more. I live on a hill with good drainage, so my surface water charge is a pittance. Meanwhile, my cousin in a low-lying postcode near Cambridge pays nearly £200 a year extra. Thanks, geography.
Adopted Rates
Also, check if your property has a water meter. Some postcodes default to unmetered rates (a flat fee), while others force metered billing. If you’re a single person, a meter can slash your bill—but if you’re a family of five, the unmetered rate might be cheaper. My single friend in a Birmingham postcode saved £150 a year just by requesting a meter install. Pro tip: ask your supplier, they’re legally obliged to offer one.
When It Gets Ironic (And Annoying)
Here’s the irony: you can’t choose your water company, but you can choose to moan about it. Ofwat allows you to compare rates across postcodes, but switching? Nope. So, if you’re stuck in a high-rate area, your only escape is moving house—or installing rainwater butts and low-flow toilets. My mate Dave got lucky with his move, but I’m now eyeing a house two postcodes over where the rates are 15% lower. Obsessive? Maybe. But it’s free money.
If you’re renting, your landlord might be paying the water bill—but check your tenancy agreement. In some postcodes, the landlord includes water in the rent, and you never see the actual rate. Ask them for a copy of the bill—it’s your right. I once discovered my landlord was charging me £20 extra per month because he “estimated” the rate. After I checked my postcode’s actual standing charge, I got a refund. Win.
