Is my service charge too high? How to tell

"Is my service charge too high?" is the single most common question leaseholders ask, and it has no simple numerical answer. Buildings differ enormously: a lift, a concierge, a communal boiler, landscaped grounds or a recent cladding remediation project all legitimately push costs up. So the honest answer is that there is no universal "right" number — but that does not leave you helpless. You can benchmark against the market, spot the patterns that usually signal a problem, and then apply the one legal test that actually decides what you owe: reasonableness.

What "normal" looks like — and why the average is only a starting point

The estate agency Hamptons put the average annual service charge for a flat in England and Wales at roughly £2,300 in 2024. That figure is useful as a sanity check, but treat it with care. It is an average across everything from a two-flat Victorian conversion with almost no shared services to a glass-and-steel new-build with 24-hour staffing — and the spread around it is vast. A low charge is not automatically a bargain (it can mean a building is being under-maintained, storing up a big bill later), and a high charge is not automatically a rip-off.

What is well established is the direction of travel. Sector analysis has repeatedly found service charges rising far faster than general inflation, driven by insurance premiums, energy costs, building-safety works and management fees. That is precisely why year-on-year comparisons matter more than the headline total.

The red flags worth investigating

Rather than staring at the grand total, look at the shape of your service charge. The following patterns are the ones that most often turn out to hide a challengeable cost.

• A large year-on-year jump. A charge that leaps 20%, 40% or more in a single year, with no obvious explanation, is the clearest signal to dig deeper. Ask what specifically changed, and demand the invoices behind the increase.
• Vague line items. Catch-all headings like "management", "sundries", "administration", "miscellaneous" or "professional fees" with no breakdown are a classic red flag. You are entitled to know what sits inside them.
• High management fees. Managing-agent fees that look large relative to the services actually delivered — or that are charged as a percentage of total spend, giving the agent an incentive to spend more — deserve scrutiny.
• Buildings insurance with commissions. Insurance is often the biggest single line. Premiums can be inflated by undisclosed commissions paid to the freeholder or managing agent. Ask for the policy, the premium and details of any commission.
• Major works with no consultation. Big one-off repair or improvement projects — a new roof, lift replacement, external decoration — that appear without a formal Section 20 consultation may be capped by law. See major works.
• A large balancing charge. A hefty year-end balancing charge — the "top-up" demanded because actual spend exceeded the on-account estimate — can mean the budget was set unrealistically low, or that costs ran away without warning.

The test that actually decides it: Section 19 reasonableness

Here is the point that changes everything. Whatever the number, a service charge is only legally payable to the extent that it is reasonable. Under Section 19 of the Landlord and Tenant Act 1985, relevant costs are taken into account only to the extent they are reasonably incurred, and where they relate to works or services, only if those works or services are of a reasonable standard. If a cost fails either limb, it is limited accordingly.

Two things follow. First, "too high" in the legal sense does not mean "higher than average" — it means higher than was reasonable for the work actually done. Second, you challenge specific costs, not the total on its own. A £5,000 charge made up entirely of well-evidenced, competitively-priced, necessary work is reasonable; a £1,500 charge padded with an inflated insurance commission and an unexplained "sundries" line may not be.

What "reasonable" means in practice

Reasonableness is judged item by item. In practice the tribunal — and you, when you investigate — will look at whether the work was actually necessary, whether the price paid was in line with the going rate (were competitive quotes obtained?), whether the standard of work was acceptable, and whether the correct process was followed (for example Section 20 consultation on qualifying works). "Reasonably incurred" does not mean the cheapest possible option — a landlord can choose a good contractor over a bad cheap one — but it does mean the cost has to be justifiable.

How to compare: benchmark like with like

Benchmarking is how you turn a gut feeling into evidence. Work through three comparisons:

1. Against your own previous years. Line up the last three or four years of accounts side by side. Which items rose, and by how much? Steady inflationary creep is expected; a single line doubling is not.
2. Against similar local buildings. Compare with blocks of similar age, size and facilities near you. A building with a lift and concierge is not comparable to a three-flat conversion — match the features. Our free Service Charges Map lets you see what leaseholders in comparable buildings are actually paying.
3. Against the market rate for each service. For the big lines — insurance, cleaning, management, gardening — you can get independent quotes to see whether the price paid is in the normal range.

What to do next

If your benchmarking throws up red flags, the next step is information, not confrontation. You have statutory rights to see what sits behind the demand. Under Section 21 of the Landlord and Tenant Act 1985 you can request a written summary of the costs, and under Section 22 you can inspect the invoices, receipts and contracts that support it, free of charge. Put the request in writing and keep a copy.

Once you can see the invoices, you can decide which items to question — and, if the landlord or managing agent will not resolve it, apply to the First-tier Tribunal under Section 27A for a binding decision. Our full walkthrough is here: how to challenge your service charges.
