Unmeasured bills explained
If you do not have a water meter, you will be charged a fixed cost each year based on your property. Here, we break down the bill so you know what you're being charged for, and what you need to do.
Your 2025 Bill
Here's all you need to know
If you don't have a water meter, you'll receive your annual bill from us sometime in February or March.

The amount we charge is different for all properties. We bill from 1st April to 31st March, or from your move in date to 31st March if you have recently moved in. A fixed rate for the year is based on:
- Property size
- Number of rooms
- Local amenities
- Property location
- General condition
We do not bill for the amount of water you use, or the number of people at your property. If you would prefer to be billed for the amount of water you use, you can use our calculator to estimate your usage and charges then apply for a meter online.

or

Download What happens when I get my bill?
We will send your unmeasured bill once a year between February and March for charges from 1st April to the following 31st March (like your council tax bill).
Your bill has to be paid in 14 days of receipt unless you have a Direct Debit or payment plan in place. If you pay your bill by 1st April, you will get a 1.5% discount off your charge.
Direct Debit is the easiest way to pay as you can spread the cost over a year, and we'll take the payments automatically. For more information, take a look at our Direct Debit page.
If you have a payment plan in place but fail to keep to the arrangement, the full outstanding balance will be payable.
If you're moving house
If you move out of an unmeasured property before 31st March and your bill was paid in full, any over payment will be refunded or transferred to your new address, so you will not lose out.
