Double-entry bookkeeping requires every transaction to be recorded as both a debit and a credit . Understanding how to construct these entries is essential for anyone managing UK business accounts. This article provides practical, worked examples covering the transactions that UK businesses encounter most frequently.

For the underlying principles, see our guide to double-entry bookkeeping .

Quick reference: debit and credit rules

Before working through examples, the core rules are worth restating:

Account typeDebit increasesCredit increases
AssetsYes
LiabilitiesYes
EquityYes
Revenue / IncomeYes
ExpensesYes

Every journal entry must have total debits equal to total credits.

Sales transactions

Cash sale (no VAT)

A sole trader sells goods for £500 and receives immediate payment.

AccountDebitCredit
Bank£500
Sales revenue£500

The bank (asset) increases. Revenue increases.

Credit sale with VAT

A limited company invoices a customer £2,000 plus 20% VAT (£400), totalling £2,400.

AccountDebitCredit
Trade debtors£2,400
Sales revenue£2,000
VAT output (liability)£400

Trade debtors (asset) increase by the full invoice amount. Revenue is recorded net of VAT. The VAT owed to HMRC is a liability.

Customer pays the invoice

When the customer pays the £2,400:

AccountDebitCredit
Bank£2,400
Trade debtors£2,400

Cash increases; the debtor balance is cleared. No revenue is recorded here – it was already recognised when the invoice was raised.

Purchase transactions

Cash purchase (no VAT)

A business buys office supplies for £120 cash.

AccountDebitCredit
Office supplies expense£120
Bank£120

The expense increases. Cash decreases.

Credit purchase with VAT

The business receives a supplier invoice for £800 plus 20% VAT (£160), totalling £960.

AccountDebitCredit
Purchases / cost of sales£800
VAT input (asset)£160
Trade creditors£960

The expense is recorded net of VAT. The reclaimable VAT is an asset. Trade creditors (liability) increase.

Paying the supplier

When the business pays the £960:

AccountDebitCredit
Trade creditors£960
Bank£960

The creditor liability is cleared. Cash decreases.

VAT settlement

Paying VAT to HMRC

At the end of the VAT quarter, the business owes HMRC £3,200 (output VAT of £5,000 less input VAT of £1,800).

AccountDebitCredit
VAT output (liability)£5,000
VAT input (asset)£1,800
VAT control / HMRC payable£3,200

When the payment is made:

AccountDebitCredit
VAT control / HMRC payable£3,200
Bank£3,200

Payroll

Recording monthly salaries

The company’s gross payroll is £10,000. Deductions are PAYE income tax £1,500, employee National Insurance £800 and employee pension contributions £400. The net pay is £7,300.

AccountDebitCredit
Salary expense£10,000
PAYE liability£1,500
Employee NIC liability£800
Pension liability (employee)£400
Net pay liability / Bank£7,300

Employer’s National Insurance and pension

The employer’s NIC is £1,100 and employer pension contributions are £300.

AccountDebitCredit
Employer NIC expense£1,100
Employer pension expense£300
Employer NIC liability£1,100
Pension liability (employer)£300

Paying HMRC

When PAYE, employee NIC and employer NIC are paid to HMRC:

AccountDebitCredit
PAYE liability£1,500
Employee NIC liability£800
Employer NIC liability£1,100
Bank£3,400

Fixed assets

Purchasing a fixed asset

The business buys a delivery van for £24,000 plus VAT (£4,800).

AccountDebitCredit
Motor vehicles (fixed asset)£24,000
VAT input (asset)£4,800
Bank£28,800

Depreciation

The van is depreciated over four years using the straight-line method. Annual depreciation is £6,000.

AccountDebitCredit
Depreciation expense£6,000
Accumulated depreciation – motor vehicles£6,000

The expense reduces profit. Accumulated depreciation is a contra asset that reduces the carrying value of the van on the balance sheet.

Year-end adjustments

Accruing an expense

The business owes £900 for electricity consumed in the year but not yet invoiced at the year end.

AccountDebitCredit
Electricity expense£900
Accruals (liability)£900

Writing off a bad debt

A customer owing £1,200 has gone into liquidation and will not pay.

AccountDebitCredit
Bad debt expense£1,200
Trade debtors£1,200

If the original sale included VAT and the debt is over six months old, the business can reclaim the VAT from HMRC through a bad debt relief claim.

Tips for recording journal entries

  • Always check that debits equal credits before posting
  • Include a clear narrative describing the transaction
  • Reference the source document (invoice number, receipt, contract)
  • Post entries to the correct accounting period
  • Use the correct VAT treatment for each transaction
  • Review entries as part of the regular bank reconciliation process
