- A typical landlord's bank statement
- Rent through a letting agent: gross it up
- Tenancy deposits: never income
- Repairs, improvements and the mortgage
- Keeping properties separate
- A landlord's monthly checklist
Good bookkeeping for landlords UK owners can rely on comes down to three habits: record rent at the full amount even when an agent pays you less, keep tenancy deposits out of your income, and split repairs, improvements and mortgage payments properly. Get those right and your property records will reconcile to the bank every month, whether you have one flat or ten.
A typical landlord's bank statement
Sunita owns three flats in Nottingham. Two are managed by a letting agent; the third she lets herself. Her bank statement for October 2026 shows:
- One payment from the agent: £1,668.00
- One standing order from her own tenant: £875.00
- Three mortgage direct debits
- A plumber's invoice she paid directly
- A £1,200.00 deposit from a new tenant
At a glance, that looks like rental income of about £3,700. It isn't. The agent payment is a net figure, the deposit isn't income at all, and the mortgage payments are partly loan repayment. Let's take each in turn.
Rent through a letting agent: gross it up
Letting agents collect rent, take their fee and any costs they've paid for you, then send the rest. The statement they send you each month is your source document. Don't record the bank receipt as rent.
Sunita's agent statement for October 2026:
| Line | Flat 1 (£) | Flat 2 (£) | Total (£) |
|---|---|---|---|
| Rent collected | 1,050.00 | 1,050.00 | 2,100.00 |
| Management fee (12%) | (126.00) | (126.00) | (252.00) |
| Plumber, leaking tap | (180.00) | 0.00 | (180.00) |
| Paid to landlord | 744.00 | 924.00 | 1,668.00 |
Check: £2,100.00 − £252.00 − £180.00 = £1,668.00. That's the amount in the bank.
So the books get:
- Rent income: £2,100.00 (split by flat if you track properties separately)
- Agent fees: £252.00
- Repairs: £180.00
- And the £1,668.00 bank receipt matched against all three
If Sunita had recorded £1,668.00 as rent, her income would be understated and her costs would be missing £432.00. Across a year that distorts the picture of which flat actually earns its keep.
A neat way to handle agents is an "agent clearing" account. Rent goes in at gross, fees and costs come out, the payment to you comes out, and the account should sit at zero after each statement. If the agent holds a float for repairs, the clearing account will show that float, which is correct.
Tenancy deposits: never income
A tenancy deposit belongs to the tenant until the end of the tenancy. In England and Wales, deposits for assured shorthold tenancies must be protected in a government-approved scheme within 30 days of receiving them. Scotland and Northern Ireland have their own schemes and rules, so check which apply to you.
How it hits your books depends on the type of scheme:
Custodial scheme. The scheme holds the money. If the deposit passes through your bank on its way to the scheme, record it in and out against a "deposits held" account. Net effect: nothing on your P&L, nothing left on your balance sheet.
Insured scheme. You (or your agent) keep the money and pay the scheme to insure it. The deposit sits in your bank, so it must sit on your balance sheet as a liability: money you owe the tenant.
Sunita's new tenant on the self-managed flat paid £1,200.00 into an insured scheme arrangement, so:
- Bank: +£1,200.00
- Tenant deposits held (liability): £1,200.00
When the tenancy ends, say she and the tenant agree a £150.00 deduction for cleaning:
| £ | |
|---|---|
| Deposit held | 1,200.00 |
| Returned to tenant | (1,050.00) |
| Kept for cleaning | (150.00) |
| Deposit liability remaining | 0.00 |
The £150.00 she keeps goes to income (or offsets the cleaning cost, if you'd rather show it that way). The £1,050.00 refund clears the liability. At no point did the £1,200.00 count as rent.
Some landlords keep insured-scheme deposits in a separate bank account. It's not a requirement in every case, but it makes it very hard to spend money that isn't yours.
Repairs, improvements and the mortgage
Repair or improvement?
A repair puts something back as it was: fixing a leak, replacing a broken pane, repainting. An improvement makes it better or adds something new: an extension, a loft conversion. In the books, repairs are expenses and improvements are usually added to the property's cost on the balance sheet.
The grey areas (a new kitchen replacing a tired one, say) are exactly where your accountant earns their fee. Record the bill with a clear description and let them classify the tricky ones.
Mortgage payments
A repayment mortgage payment is two things: interest (a cost) and capital (repaying the loan). Say a monthly payment is £640.00, of which £410.00 is interest and £230.00 is capital. Record:
- Mortgage interest: £410.00
- Mortgage loan (liability) reduced by: £230.00
Your lender's annual statement shows the split. If you only have the monthly figure, record it to the loan account and flag it so the interest can be split out at year end. What you shouldn't do is call the whole £640.00 an expense.
Keeping properties separate
Even with one bank account, you'll want to know how each property is doing. Simple options:
- A category per property for rent (for example "Rent: Flat 1")
- A property reference in every expense description
- A separate bank account per property, if you own several and the volume justifies it
Joint owners should agree early how income and costs are split, and record it consistently, because it needs to be clear at year end.
A landlord's monthly checklist
- [ ] Agent statements saved and recorded at gross
- [ ] Agent clearing account back to zero (or to the known float)
- [ ] Self-managed rent received and matched to each tenant
- [ ] Missing or late rent chased
- [ ] Deposits recorded as liabilities, with scheme details noted
- [ ] Repairs and improvements described clearly
- [ ] Mortgage payments split into interest and capital, or flagged for the accountant
- [ ] Bank account reconciled to the statement
How HelloBooks helps
Connect your bank through Open Banking (most UK banks and cards) or import a CSV statement. Rent, agent payments and bills land in a review list where you confirm or change categories, and the reconcile screen suggests a match for each line with a confidence score and its reasoning, so you only handle the exceptions. You get a P&L, balance sheet and cash flow, so deposits held and the mortgage balance show up where they belong.
The Free plan covers one live bank feed and up to 200 transactions per year, which many single-property landlords fit comfortably within. If you have several accounts or a busier portfolio, Pro (£14.99 a month) gives unlimited bank connections and recurring invoices. You can also invite your accountant into the same books.

FAQs
Should I record rent when it's due or when it arrives?
Day to day, many landlords record it when it arrives. If you want a clear view of arrears, raise the rent as an invoice when due so unpaid rent shows in your debtors.
My agent statement covers a different period to the calendar month. Is that a problem?
No. Record each statement on its date and match it to the bank receipt. The clearing account keeps everything tidy across period boundaries.
Does a deposit held by my agent go in my books?
If the agent holds it and protects it, it usually doesn't touch your bank, so it may not appear in your books at all. Note it in your records so you know it exists.
Are letting agent fees an expense?
Yes, they're a cost of letting the property. Record them from the agent statement, not by guessing from the bank figure.
What's the most common landlord bookkeeping mistake?
Recording the agent's net payment as rent. It understates income and hides costs, and it makes every property look the same when they rarely are.
Gross up the rent, park the deposit, split the mortgage, and your property books will tell you the truth.
