Service Charge Accounting for Self-Managed Blocks: A Step-by-Step Guide

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:

Category	Typical Items	Notes
Insurance	Buildings insurance, D&O insurance	Get 3 quotes annually
Maintenance	Cleaning, gardening, communal lighting, minor repairs	Based on prior year + planned works
Major works provision	Reserve/sinking fund contribution	For future roof, windows, lift refurbishment
Professional fees	Accountant, solicitor (if needed)	Year-end accounts preparation
Utilities	Communal electricity, water (if applicable)	Based on prior year usage
Health & safety	Fire risk assessment, alarm servicing, emergency lighting, legionella checks	Legal requirements
Companies House	Confirmation statement filing fee	£50 online
Contingency	Unplanned repairs	Typically 5-10% of total budget

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.

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:

Unit	Lease Percentage	Annual Demand	Quarterly Demand
Flat 1 (ground, small)	12%	£1,440	£360
Flat 2 (ground, large)	18%	£2,160	£540
Flat 3 (first, small)	14%	£1,680	£420
Flat 4 (first, large)	20%	£2,400	£600
Flat 5 (second, small)	16%	£1,920	£480
Flat 6 (second, large)	20%	£2,400	£600
Total	100%	£12,000	£3,000

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 Sections 47–48 of the Landlord and Tenant Act 1987: every demand must include the name and address of the landlord (your RTM/RMC company). A demand without this information is not valid — the leaseholder is not obliged to pay until you correct it.

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: reminder at 14 days, formal letter at 30 days, then FTT or county court if necessary. Use our free Arrears Letter Generator for template chase letters.

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

At the end of each accounting year, you must produce service charge accounts and make them available to leaseholders. The accounts should follow the guidance in the RICS Service Charge Residential Management Code.

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.

Accounts must be made available to leaseholders within six months of the end of the accounting year, under RICS best practice guidance.

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 company name and address is legally invalid

When to use an accountant

For most small blocks (4-15 flats), directors can prepare the accounts themselves using a spreadsheet or 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.
