Service Charge Accounting for Self-Managed Blocks

Service charge accounting is the core financial obligation for every RTM and RMC director. You need to budget for the year ahead, collect contributions from leaseholders, track expenditure, and produce year-end accounts that follow the standard format. Most volunteer directors do this with a spreadsheet and a lot of guesswork.

This guide walks through the full annual cycle — from setting the budget to producing compliant year-end accounts.

The annual service charge cycle

Step 1: Set the annual budget

Before the start of each accounting year, directors must set a budget covering all anticipated costs. Common budget categories for a residential block:

How to set the budget: Review the previous year's actual expenditure. Adjust for known changes (insurance premium increase, planned maintenance, inflation). Add a contingency. The budget should be realistic — overestimating creates unnecessarily high demands; underestimating creates a deficit that needs covering later. For a full step-by-step walkthrough of the budget planning process — including how to set the reserve fund contribution, calculate individual demands, and avoid common planning mistakes — see our service charge budget planning guide.

Step 2: Calculate individual demands

Each leaseholder's contribution is determined by their lease percentage — the share of total costs they are responsible for, as specified in their lease.

Example for a 6-flat block with a £12,000 annual budget:

Check your leases carefully — percentages are sometimes based on floor area, sometimes on rateable value, and sometimes on equal shares. They must add up to 100%.

Step 3: Issue service charge demands

Demands must comply with section 47 of the Landlord and Tenant Act 1987: every demand must include the name and address of the landlord (your RMC, if it owns the freehold; for an RTM company, the position is more nuanced and worth checking). Until it does, the service charge is not yet due — giving the details by notice puts it right.

Demand frequency options:

• Annual: One demand at the start of the year. Simple but creates cash flow issues — you need the full year's costs upfront.
• Half-yearly: Two demands. Better cash flow.
• Quarterly: Four demands. Best for cash flow and most common for self-managed blocks. Also reduces the risk of the 18-month rule catching you out.

Step 4: Track payments and chase arrears

Record every payment against each unit. Reconcile bank statements monthly — or at minimum quarterly — to ensure payments match demands.

For unpaid demands, follow the arrears recovery process: write early, write more than once, and escalate only on a route your lease gives you and after the applicable pre-action requirements are met.

Our free Arrears Letter Generator drafts the letters themselves — a template at one of three stages, stating what is outstanding and when it fell due, and asserting no deadline, charge or legal consequence.

Step 5: Track expenditure

Record every expense against the budget category it falls under. Keep all invoices and receipts. You'll need this detail for year-end accounts and to answer any leaseholder queries about how their money was spent.

Tips:

• Use a separate bank account for the block — never mix block funds with personal accounts
• Maintain a simple cashbook or spreadsheet with columns for: date, payee, description, category, amount
• Photograph or scan receipts as they arrive — paper fades and gets lost

Step 6: Produce year-end service charge accounts

What your block must produce at the end of each accounting year, and make available to leaseholders, is set by your lease — it is not fixed by a general statutory rule. The RICS Service Charge Residential Management Code recommends a shape for it, and most leases either require that shape or are satisfied by it. Treat the Code as best practice and a likely lease requirement rather than as law in itself, and read your own lease for what it actually obliges you to produce.

Standard format for service charge accounts:

Income section:

• Service charge demands raised
• Actual payments received
• Arrears brought forward / carried forward

Expenditure section (by category):

• Insurance
• Maintenance and repairs
• Cleaning and gardening
• Utilities
• Professional fees
• Health and safety
• Other costs

Summary:

• Total income vs total expenditure
• Surplus or deficit for the year
• Reserve (sinking) fund balance brought forward, contributions, expenditure, balance carried forward

Important: Accounts should be prepared on an accruals basis — meaning costs are recorded in the period they relate to, not when they were paid. If you paid an insurance premium in March for April-March cover, the cost belongs in the new accounting year.

When your accounts must reach leaseholders is set by your lease; RICS best practice guidance recommends producing them promptly after the year end. ⚠️ The six-month figure people quote is a different duty and it works differently: under section 21 of the Landlord and Tenant Act 1985 a leaseholder can request a written summary of the relevant costs, and you must then supply it within one month of the request or six months of the end of the period, whichever is later. That clock starts on a request, not automatically at your year end. For example accounts in the recommended format — including a worked example for a six-flat block — see our service charge accounts format guide.

Common mistakes in service charge accounting

1. Mixing block and personal funds — opens you to accusations of mismanagement and makes reconciliation impossible
2. Not reconciling bank statements — you discover errors at year-end instead of when they happen
3. Forgetting the reserve fund — the reserve fund balance must be shown separately in the accounts, not lumped with general expenditure
4. Using cash basis instead of accruals — this misallocates costs between years and doesn't match the standard format
5. Missing the 18-month deadline — costs incurred more than 18 months ago without a demand are irrecoverable
6. Not issuing compliant demands — a demand missing the landlord's name and address is not payable until corrected
7. Treating ground rent as service charge income — ground rent is due to the freeholder under the lease, not a cost of managing the block, and it carries its own demand requirements. Running it through the service charge account overstates both income and expenditure. See why ground rent is not a service charge

When to use an accountant

For most small blocks (4-15 flats), directors can prepare the accounts themselves using a spreadsheet or service charge software. An accountant is worth the cost when:

• The block has complex finances (multiple reserve funds, ongoing major works)
• You need certified or audited accounts (rare for RMCs below the audit threshold)
• There's a dispute with leaseholders about the accounts — an independent accountant adds credibility
• You simply don't have the time or confidence to do it yourself

Typical accountant fees for a small block's year-end accounts: £500-1,500. For a simple review of accounts you've prepared: £200-400.
