Not sure what site area charging means? We’ll explain it all right here.

Site area is the chargeable area of your business premises. It’s made up of the total area of your site, whether the surface is permeable or not. It excludes any permanently grassed, cultivated or landscaped areas where no surface water or ground water drains directly or indirectly to a public sewer.

What is surface water and highways drainage?

On your water bill you’ll see a charge called ‘surface water drainage’. Surface water is rainfall which falls onto your premises and flows directly or indirectly into the public sewer. This charge is for taking away the rainwater that falls onto your business premises. How much you pay for surface water drainage depends on your chargeable area.

How are the charges set?

If you have a connection to a public sewer then these charges apply to you. Once your chargeable area has been worked out, your premises will be placed in a site area charging band, which will determine how much you’ll pay. You can find out more about how we calculate your charging band here.
