If you have a home based business your property may be classed either as domestic or dual use. 

This will be determined by the local assessor. If it is domestic, then you can continue paying for your water and waste water through your council tax. For information about apportionment notes, please see the SAA portal at www.saa.gov.uk

If your property is classed as having domestic and non-domestic parts, and does not have an apportionment note, then it will be dual use and treated as both. Any property parts that are domestic will be billed at the same time as council tax. 

The business will be liable for paying for any water, waste water or drainage services it receives. You will need to appoint a Licensed Provider (LP) for these services. 

If your property is classed as having domestic and non-domestic parts, and has an apportionment note, then it will be classed as part-residential. You will pay only through your Licensed Provider and will not pay for any water services at the same time as council tax.
