You will have to pay business and water rates on your premises (if you have any). The local rating authority, the estate agent and your local water company will be able to give you some guidance as to how much these will be.
When you start a new business and/or move into new business premises, your local authority will normally send you a business rates bill for the correct amount. Then every year you'll get a new bill for the forthcoming tax year, usually in February of March.
You may be eligible for a discount on your business rates under a business rates relief scheme. Relief schemes vary around the UK, so it's best to contact your local authority to find out if you are eligible and if so how to make an application. Your local authority will apply some reliefs automatically, but you will have to apply for others that you may be eligible for.
Business rates are normally paid in ten monthly instalments between April and January. However, some councils also give businesses the option to pay quarterly, half yearly and/or annually. Water rates are generally paid monthly, although some water companies give the option of paying them annually in advance.
Your water supply and effluent disposal charges in particular are likely to be high. Note that water supply and effluent charges vary considerably from one part of the UK to another. Check your water bills carefully. Errors can and do occur and it is your responsibility to identify them and claim a rebate. Do what you can to avoid wasting water.
Enter in the cash flow the amounts payable in the months you have decided to pay them.
