Cash Flow Forecasting UK —
See Pressure Before It Arrives
Forward-looking cash flow forecasting for UK businesses, using agreed assumptions, receipts, payments and scenarios to help management plan liquidity, funding and working-capital decisions.
Forecast Liquidity with Transparent Assumptions
A cash flow forecast estimates when cash is expected to enter and leave the business. It can help identify periods where the business may need to accelerate collections, defer spending, arrange funding or revisit assumptions.
A 13-week model is often useful for short-term liquidity management because it focuses attention on the timing of receipts and payments. A longer 12-month view can support budgeting, growth planning and financing discussions.
The model is only as useful as its assumptions. Britvex therefore separates opening cash, committed items, expected receipts, payroll, tax, supplier payments, financing and scenario assumptions so management can see what drives the forecast.
Forecasts are not guarantees. Actual results will differ as trading conditions, customer payment behavior, tax liabilities, financing and management decisions change.

Cash Flow Forecasting — Common Questions
What is a 13-week cash flow forecast?
It is a short-term rolling model of expected cash receipts and payments over approximately three months. It is commonly used for liquidity management and working-capital planning.
Can you prepare a 12-month forecast as well?
Yes. A longer forecast can be prepared where the business needs budgeting, growth, financing or scenario planning over a wider period.
Is a cash flow forecast guaranteed to be accurate?
No. It is based on assumptions and information available at the time. Actual trading, payment timing and other events will cause results to differ.
Can the forecast support a bank application?
It can form part of the financial information requested by a lender, but the bank may require a particular format, supporting evidence or additional information.
How often should the forecast be updated?
That depends on how quickly the business changes. Businesses with tighter liquidity or rapid growth may benefit from more frequent rolling updates.
