Definition

The profit and loss (P&L) statement summarises the revenues, costs and expenses incurred during a specific accounting period, resulting in a net profit or net loss. Under FRS 102, the equivalent is the "statement of comprehensive income". Under the Companies Act 2006, UK companies must file a profit and loss account as part of their statutory accounts (subject to small company exemptions).

Why this matters for Accounting Principles & Procedures

  • Level 1 knowledge: you must be able to identify the main line items of a P&L and explain what each represents.
  • Assessors commonly show a simplified P&L and ask candidates to interpret margins, identify trends or explain the significance of a line item.
  • A surveying firm's own P&L is the primary tool for measuring whether the business is achieving its financial objectives, including fee income targets and overhead ratios.
  • The P&L links directly to the balance sheet (through retained profit) and the cash flow statement, making it impossible to understand a company's financial position without reading all three together.

Key principles

Structure of a P&L

Revenue (turnover) is income from principal activities, recognised on an accruals basis. Deducting cost of sales gives gross profit. Deducting administrative and operating expenses (overheads, salaries, depreciation) gives operating profit (EBIT). After finance income and costs, the result is profit before tax (PBT). Deducting Corporation Tax gives profit after tax, which flows to retained earnings on the balance sheet.

Revenue recognition for a surveying firm

Under FRS 102 Section 23, revenue from services is recognised by reference to the stage of completion at the reporting date (where the outcome can be estimated reliably). For a long-running instruction, fee income is recognised progressively as work is performed. Firms must ensure work in progress is properly accrued to avoid understating income.

Gross and operating profit margins

The gross profit margin (gross profit ÷ revenue) measures how efficiently a business converts sales after direct costs. The operating profit margin (operating profit ÷ revenue) shows the additional impact of overheads. Comparing the two reveals whether a profitability problem lies in the direct cost structure or the overhead base.

EBITDA and its uses

EBITDA (earnings before interest, tax, depreciation and amortisation) is a proxy for operating cash generation widely used in valuations and covenant calculations, derived by adding back depreciation and amortisation to operating profit. It is not a statutory measure and is not defined by accounting standards.

Relevant RICS guidance and legislation

  • FRS 102: The Financial Reporting Standard applicable in the UK and Republic of Ireland — Section 5 (statement of comprehensive income) and Section 23 (revenue) govern the preparation of the P&L.
  • Companies Act 2006 — requires companies to prepare a profit and loss account as part of annual accounts; sets out statutory formats.
  • IFRS 15: Revenue from Contracts with Customers — applies to listed companies and sets out the five-step revenue recognition model.
  • HMRC Corporation Tax guidance — taxable profit is calculated from accounting profit with specific adjustments; understanding the P&L is a prerequisite for understanding the tax computation.
  • RICS Rules of Conduct (effective 2 February 2022) — Rule 5 (competent service) requires members to understand the financial context of the businesses they advise or work within.

Ethics and Rules of Conduct angle

Rule 3 of the RICS Rules of Conduct requires members to act with integrity. Any surveyor involved in preparing or signing off accounts must ensure those accounts are not manipulated to misrepresent performance. Premature revenue recognition, inflated work-in-progress valuations or failure to accrue known liabilities can all constitute financial misrepresentation. If a candidate is asked to adjust figures incorrectly, they should raise the concern through appropriate channels and, if necessary, via RICS whistleblowing procedures.

APC-style Q&As

Q (Level 1)What is the difference between gross profit and net profit?

Gross profit is revenue minus cost of sales (direct costs). Net profit (profit after tax) is what remains after also deducting operating expenses, finance costs and the Corporation Tax charge. Gross profit measures the efficiency of the core business activity; net profit measures the overall financial return to shareholders.

Q (Level 1)What does the accruals basis mean in the context of a P&L?

The accruals basis means that income is recognised when earned and expenses when incurred, regardless of when cash changes hands. For a surveying firm, fee income is recognised as work is completed and costs are matched to the period they relate to, even if invoices are paid before or after the period end.

Q (Level 2)A surveying firm has a gross profit margin of 45% but an operating profit margin of 8%. What does this tell you?

The firm is generating a reasonable gross return, but a large proportion is consumed by overheads. The gap of 37 percentage points suggests overhead costs are high relative to revenue. The firm should analyse its cost structure to identify whether overheads can be reduced or whether revenue must increase to support them.

Q (Level 2)How does a long-term instruction affect revenue recognition in a surveying firm's P&L?

Under FRS 102 Section 23, revenue from services is recognised by reference to stage of completion at the reporting date. A proportion of the agreed fee is recognised in each accounting period as work is performed, with the balance shown as work in progress until billed. Failing to accrue work in progress would understate revenue and profit, potentially misleading management and investors.

Q (Level 3)A property investment company's P&L shows a large profit almost entirely driven by an investment property revaluation gain. How would you advise a client who asks whether this means the business is performing well?

(example) I would advise the client not to rely on the headline figure. Under FRS 102 Section 16, investment property revaluation gains pass through profit or loss, inflating reported profit without generating any cash. The gain is unrealised and does not help the business meet its obligations. I would direct the client to examine rental income, occupancy rates, interest cover and the cash flow statement before drawing conclusions about financial health.
