Your Client Runs a Seasonal Business: How Might a Mortgage Lender Assess Their Income?

The Client Situation

Seasonality may be obvious or hidden. It affects:

• hotels, holiday lets and visitor attractions;
• restaurants, pubs and wedding venues;
• agriculture, horticulture and food production;
• retailers dependent on Christmas or summer sales;
• events, exhibitions and entertainment;
• construction trades affected by weather or project cycles;
• education, childcare and term-time services;
• accountancy or professional firms with annual deadlines;
• e-commerce businesses with campaign peaks;
• property developers with completion-led revenue;
• recruitment and consulting firms with bonus cycles; and
• businesses that buy stock months before selling it.

The mortgage request can arrive during a predictable cash trough, just after a strong peak, or when the latest accounting year has an unusual number of peak weeks. Each timing can distort a snapshot.

Map the Full Trading Cycle

A 12- or 24-month monthly profile usually explains more than a single year-to-date total. Mark the operational triggers: opening dates, harvest, school terms, customer renewals, deposits, final invoices and tax deadlines.

Annual Profit and Monthly Cash Answer Different Questions

A profitable annual business can fail if it cannot fund the low season. A cash-rich peak month can be misleading if VAT, Corporation Tax, suppliers and winter payroll remain unpaid. Mortgage affordability and company resilience need both lenses.

What a Mortgage Lender May Examine

Depending on the client’s structure and lender policy, underwriting may consider:

• two or three years of full annual accounts or tax returns;
• annual profit trend and latest completed year;
• salary, dividends, drawings or retained profit;
• current management accounts with monthly breakdown;
• same-period prior-year comparisons;
• rolling 12-month sales and profit;
• company and personal bank statements;
• cash reserves at both peak and trough;
• stock, debtors and creditors;
• tax liabilities and payment history;
• overdraft, invoice finance and other seasonal facilities;
• contracts, bookings, deposits and cancellations;
• weather, commodity, tourism or customer concentration; and
• the proposed mortgage payment throughout the low season.

Some residential lenders use only completed historic income. Specialist policies may review current evidence, but a forecast does not automatically replace signed results. Willow should establish the method before the accountant produces bespoke schedules.

Compare Like With Like

Adjust for calendar effects such as Easter, school holidays, weather, events, an extra trading week or accounting periods longer or shorter than twelve months. State these adjustments; do not silently reshape the history.

Build a Forecast That Respects the Season

Business.gov.uk recommends cash-flow forecasts that show money moving in and out, identify extra funds or shortages and reflect the timing of customer payment rather than invoice date. For a seasonal mortgage case, use:

• monthly rather than flat annual profiles;
• actual completed months locked into the forecast;
• historic same-month conversion rates;
• contracted bookings separated from pipeline;
• real payroll, rent and supplier timing;
• VAT, tax and loan dates;
• stock and capital expenditure before the peak;
• base, downside and severe-but-plausible cases;
• lowest cash balance and facility headroom; and
• the proposed personal or company mortgage cost.

Do not improve the year-end profit by assuming the company delays creditors beyond normal terms without explaining the risk. A forecast should reveal the funding requirement, not hide it.

Worked Example: Profitable Year, February Cash Trough

A coastal hospitality company produced profits of £190,000, £215,000 and £205,000 over three completed years. Seventy per cent of revenue arrives from May to September. At the end of February, current management accounts show a £65,000 loss and the bank balance is £40,000, compared with £310,000 immediately after the prior summer.

The accountant’s monthly comparison shows February is normally loss-making. Bookings, deposits and margins are in line with the prior year, and a cash-flow model reaches a £25,000 low point in April before recovering. However, £80,000 of Corporation Tax is due in March and the company has a £100,000 overdraft facility.

The accountant provides annual accounts, like-for-like managements, bookings, tax schedule and sensitised cash flow. Willow identifies lenders using completed sustainable director income while ensuring the proposed mortgage remains affordable personally. If a specialist lender reviews current trade, it receives the full seasonal profile—not an annualised summer month.

The business is not judged solely by February’s loss, but the cash trough, tax and facility headroom remain real risks that cannot be removed by pointing to annual profit.

Normal Seasonality or Emerging Decline?

Test whether:

• the peak is starting later or ending earlier;
• bookings are down at the same lead time;
• prices rose but volumes fell;
• gross margin weakened;
• cancellations or bad debts increased;
• stock is growing faster than sales;
• the low-season overdraft is deeper each year;
• tax or suppliers are being deferred;
• one customer or event now dominates;
• weather or regulation changed the market;
• owner drawings exceeded annual profit; or
• the current year requires optimistic recovery to match history.

Seasonality explains timing. It should not be used to explain away a deteriorating trend. If the same-period comparison is weaker, say so and model the consequence.

What Happens to the Owner’s Income?

The owner may take equal monthly salary and dividends even though company cash is volatile, or draw heavily after the peak and little in winter. The accountant should show:

• annual salary, dividends or drawings;
• timing of each payment;
• distributable reserves where relevant;
• cash remaining after extraction;
• personal tax and payments on account;
• personal savings used during low months;
• company-funded benefits or pensions; and
• whether the mortgage payment fits the lowest-income period.

A lender may smooth verified annual income for affordability, but the client still needs a practical personal cash plan when their extraction is seasonal.

Where the Professional Boundaries Sit

The accountant prepares compliant annual accounts, management information, tax schedules and cash-flow forecasts and explains the recurring cycle and current variance. The directors remain responsible for assumptions and business decisions.

Willow identifies lenders whose income and evidence methods fit the genuine position, recommends suitable finance and coordinates underwriting. The lender chooses the usable income and stress approach.

Willow does not certify forecasts or decide accounting cut-off. The accountant should not promise that a normal seasonal trough will be ignored or that peak receipts will be annualised.

Common Mistakes to Avoid

• Annualising the peak month: it is not representative.
• Annualising the trough: it can understate the year.
• Comparing unequal months: use like-for-like periods.
• Showing profit without cash flow: the low point matters.
• Using peak bank cash: deduct tax and known liabilities.
• Treating bookings as completed sales: cancellation and delivery remain.
• Ignoring stock timing: cash leaves before revenue arrives.
• Flat-lining a forecast: seasonality must remain visible.
• Calling decline seasonal: test same-period trends.
• Forgetting facility renewals: overdraft availability may change.
• Using owner drawings alone: reconcile to sustainable annual performance.
• Applying without policy confirmation: current evidence treatment varies.

When to Involve Willow

Refer the client when:

• the mortgage application falls in the low season;
• year-to-date management accounts show a normal loss;
• a peak month makes current income look unusually high;
• company cash is materially lower before the season;
• tax falls during the cash trough;
• the owner’s drawings are highly uneven;
• the latest accounting period contains an unusual number of peak weeks;
• stock or deposits distort cash;
• the client needs a high-value mortgage before year-end;
• current same-period trading is stronger than last year;
• the accountant can provide monthly comparatives; or
• another lender misunderstood the seasonal pattern.
