If you live in a leasehold flat, you’ve probably had that moment: the annual service charge demand lands, the figure is higher than last year, and your first thought is, “But nothing has changed in the building.”
In reality, service charges can rise even when everything looks the same day to day. That’s because service charges don’t just cover visible jobs. They also cover behind-the-scenes costs like building insurance, utilities in communal areas, compliance and safety checks, and planned maintenance that protects the building long term.
In this guide, we’ll explain the most common reasons service charges increase, what you should look for in your breakdown, and how to read year-end accounts so you can understand where your money is going.
What is a service charge (and what does it pay for)?
A service charge is the amount leaseholders contribute towards the cost of managing, maintaining and repairing a building and its shared areas. What’s included depends on the terms of the lease, but commonly covers:
- Building insurance
- Cleaning and maintenance of communal areas
- Grounds maintenance
- Lighting, heating or power in shared areas
- Lift servicing and repairs (if applicable)
- Fire safety and other statutory compliance checks
- Managing agent fees and administration
- Repairs and planned maintenance
- Reserve or sinking fund contributions (where applicable)
Why service charges go up when nothing seems to change
Even when there are no obvious major works, costs can rise due to external factors and routine requirements. Here are the most common causes.
1) Building insurance premiums increase
For many blocks, building insurance is one of the largest single items in the service charge. Premiums can rise because of:
- Wider insurance market changes
- Increased rebuild costs (materials and labour inflation)
- Higher claims costs across the sector
- Fire safety and risk considerations
- Previous claims history (even if not recent)
Even if your building hasn’t changed, the insurer’s pricing and risk model might have.
What to look for: “Insurance premium”, “terrorism cover” (sometimes listed separately), insurance broker/admin fees, and the policy period being covered.
2) Communal utilities cost more (even with the same usage)
Shared electricity and utilities can climb due to:
- Energy price changes
- Contract renewal at higher rates
- Standing charges
- Increased servicing costs for communal plant (where relevant)
You might not notice any difference in day-to-day lighting or heating, but the unit price paid by the building may have increased.
What to look for: “Electricity for common parts”, “communal heating”, “water (common parts)”, “metering”, “standing charges”.
3) Compliance and safety costs are higher than they used to be
Property management has become more compliance-heavy over time. Depending on your building, service charge budgets may include costs for:
- Fire risk assessments and reviews
- Emergency lighting tests
- Smoke ventilation servicing
- Fire alarm system servicing (if installed)
- Lift inspections and servicing
- Asbestos management (where relevant)
- Electrical testing for communal areas
- Water hygiene checks (for shared systems)
Even if nothing looks different, ongoing legal and safety responsibilities still need funding, and the cost of specialist contractors often increases.
What to look for: “Compliance”, “statutory inspections”, “fire safety”, “FRA”, “EICR”, “water risk assessment”, “lift LOLER”.
4) Contractor costs rise (labour, materials and call-out rates)
Cleaning, gardening, reactive repairs and general maintenance are affected by:
- Wage increases and staffing shortages
- Fuel costs
- Materials inflation
- Increased overheads for contractors
- Higher call-out rates, especially for emergency jobs
Even small changes (for example, a higher cleaning contract rate) can add up across the year.
What to look for: “Cleaning contract”, “grounds maintenance”, “repairs and maintenance”, “handyman”, “reactive repairs”, “call-outs”.
5) Planned maintenance cycles aren’t always visible
Some buildings have maintenance cycles that happen every few years, such as:
- Internal communal redecoration
- External decoration
- Gutter cleaning and roof inspections
- Door entry system upkeep
- Minor roof repairs and patching
- Periodic servicing of plant and equipment
If your building enters a “maintenance year”, costs can increase even if the works aren’t dramatic.
What to look for: “Planned maintenance”, “cyclical works”, “decorations”, “schedule of works”.
6) Reserve (sinking) fund contributions change
Some buildings collect money into a reserve fund (also called a sinking fund) to help pay for bigger works over time. Contributions can increase when:
- Future major works are forecast
- Previous contributions were too low
- Costs of future works are rising
- The reserve balance needs strengthening
This can feel frustrating if nothing is happening right now, but it can reduce “shock bills” later when major works are unavoidable.
What to look for: “Reserve fund contribution”, “sinking fund”, “capital expenditure provision”.
7) Service charge budgets are estimates, and year-end balancing affects next year
Many service charges are set as an estimate at the start of the financial year. At year end, accounts are prepared showing actual spend. Depending on the structure for your building, you might see:
- An under-spend, which may be credited back or carried forward
- An over-spend, which may be collected as a balancing charge or factored into future budgets
So even if you feel like “nothing changed”, last year may have ended with higher-than-expected costs in one or more categories.
How to read your year-end service charge accounts (a simple checklist)
Year-end accounts can look intimidating, but you can often make sense of them by checking a few key areas.
1) Start with the summary page
Look for:
- The accounting period covered
- Total expenditure vs total budget
- The surplus/deficit position
- Notes on any exceptional items
2) Compare budget vs actual line by line
Focus on the biggest variances first:
- Insurance
- Utilities
- Repairs and maintenance
- Compliance
- Management fees
- Reserve fund
If one line has jumped significantly, that usually explains most of the increase.
3) Check reserve fund movement (if applicable)
You may see:
- Opening balance
- Contributions collected
- Amount spent from the fund
- Closing balance
If the reserve is being used for planned items, ask what’s planned next.
4) Look for notes about one-off costs
Examples might include:
- Emergency repairs
- Storm damage
- Unplanned plant failure
- Specialist surveys
- Legal/accountancy costs (where relevant)
One-off items can cause a temporary spike.
5) Understand how costs are apportioned
Your share may be based on:
- Floor area
- A percentage stated in the lease
- An equal split between flats (less common)
If your share seems different from what you expected, check the apportionment method set out in your lease.
What should you do if you’re concerned about an increase?
If you’re unhappy or confused, the best next step is usually to ask for clarification in a structured way.
Useful questions include:
- Which line items increased the most and why?
- Were there any one-off costs this year?
- Is the building insurance currently being reviewed or tendered?
- Are any works planned that will affect next year’s budget?
- Is a reserve fund in place, and what is it intended to cover?
- Can you share the year-end accounts and supporting breakdown (if not already provided)?
Keeping questions specific makes it easier to get clear answers.
Key takeaway
Service charges can go up even when the building looks unchanged because many costs are driven by market pricing (insurance and utilities), ongoing legal and safety responsibilities, contractor cost inflation, and long-term maintenance planning.
Understanding your budget, year-end accounts, and (where applicable) reserve fund helps you see the reasons behind the numbers and plan ahead.
If you’ve had a service charge increase and want help understanding the breakdown, speak to your managing agent. They should be able to talk you through the key drivers and the documents behind the figures.
