How is my chargable area measured
Technical details you need to know
When calculating your chargeable area, we measure the total site area of your premises (whether or not the surface area is permeable) and then exclude any permanently grassed, cultivated or landscaped areas. Examples of excluded areas are playing fields, farmland, racecourses, sports grounds, golf courses, parklands or areas of land on which no building is allowed by law.
Example of how we calculate your site area measurement
- Total site area of the premises: 1351m2
- Exclude any permanently grassed, cultivated or landscaped areas: 470m2
- Chargeable area: 881m2
- This equates to Band 4 please see our bands and charges for 2011-2012
Your chargeable area determines how much you pay for your surface water drainage and highway drainage services. Our charges for these services are structured into 15 charging bands (with charging band 1 being the smallest size and the lowest charge).
We use our own digital mapping systems and those of Ordnance Survey to calculate your chargeable area, and the charging band that has been allocated to your premises will be shown on your latest wastewater bill.
If you believe that you are being charged on the wrong band, you can contact us on 0845 746 2255.
There are a number of ways that you may be able to reduce site area charges.
