Service charges on UK apartments now average £4,120 a year in London, according to Rightmove data analysed by PropertyData. In some postcodes, that figure climbs past £19,000. These costs have been rising faster than inflation, and 2024 recorded the biggest annual jump since tracking began in 2016. For anyone buying a leasehold flat, the monthly service charge can end up costing more than the mortgage payment itself.

More than half of leaseholders now pay more in service charges than they do in council tax. The gap between flat and house prices has also widened sharply — in 2015 the average flat cost £161,000 against a house at £218,000. A decade later, the average flat sits at £191,000 while the average house has jumped to £321,000, according to Zoopla data. High service charges are a major reason buyers are walking away from flats. Here’s what you actually need to know.
What You Need to Know About Service Charges Before You Buy
A service charge is the annual fee you pay to your landlord or managing agent for the upkeep of the building’s communal areas. It typically covers buildings insurance, cleaning, gardening, repairs, fire risk assessments, and the managing agent’s own fees. Some blocks add gyms, concierges, and parking — and the bill rises accordingly.
What I tend to notice is that most buyers focus on the purchase price and the mortgage rate, then discover the service charge only after the offer is accepted. By then, the lease is signed and the monthly obligation is locked in. The figure that matters most is the charge as a percentage of the property price — anything above 2% is worth weighing carefully against resale value.
Where Your Money Goes: Regional Service Charge Breakdown
Service charges vary wildly by location, and the gap between London and the rest of the country is only part of the story. Within London, a postcode can make a £15,000 difference per year.

| Location | Average Annual Service Charge | Monthly Equivalent |
|---|---|---|
| W1S (Mayfair) | £19,859 | £1,655 |
| WC2R (Strand) | £17,369 | £1,447 |
| SW1E (Victoria) | £16,604 | £1,384 |
| London average | £4,120 | £343 |
| Reading | £2,926 | £244 |
| Wolverhampton | £2,924 | £244 |
| Manchester | £2,528 | £211 |
| Bournemouth | £2,515 | £210 |
These figures are averages, meaning some individual flats pay far more. A two-bed apartment in Clerkenwell was recently listed with a £28,151 annual service charge — 3.6% of its £775,000 asking price. At the extreme end, a Knightsbridge three-bed apartment worth £7 million carried a £150,000 annual charge.
The full cost picture goes beyond the headline figure. Service charges pay for buildings insurance, which has risen sharply under the Building Safety Act. They also fund sinking funds for major works, and those can land as one-off bills worth tens of thousands. A waterfront apartment in London recently saw a £150,000 service charge on a 2,520 sq ft unit — a figure that would wipe out most buyers’ savings.
Three Costly Service Charge Mistakes That Catch Buyers Out
Buying Without Checking the Service Charge History
Most buyers ask about the current year’s service charge but never look at the trend. Charges have been rising ahead of inflation for years, and 2024 saw the biggest annual increase since Hamptons began tracking them in 2016. If the charge has jumped 10% or more in each of the last three years, the trajectory matters more than the current figure. Request the last five years of service charge statements from the seller or managing agent. If they refuse, that’s a red flag. What I’d do is ask for the budget for the coming year too — it shows whether the managing agent is planning further increases.
Ignoring the Section 20 Major Works Process
Under Section 20 of the Landlord and Tenant Act 1985, landlords must consult leaseholders before carrying out major works that would cost any tenant more than £250. If they don’t consult properly, the amount you have to pay can be capped at £250 per flat. The problem is that many leaseholders receive little or no notice and have no time to find the money. The government’s current consultation on strengthening leaseholder protections specifically targets this process, aiming to make it fit for purpose. If you’re buying, check whether any major works are planned and whether the seller has received a Section 20 notice. Ask for the sinking fund balance — a well-funded sinking fund should cover planned works without a sudden demand.
Accepting Charges Without Questioning Them
Service charges are the single biggest subject of enquiry among leaseholders seeking advice from the Leasehold Advisory Service. Yet many flat owners simply pay the bill without checking what it covers. The Housing Ombudsman has found severe maladministration in cases where landlords withheld refunds for charges that weren’t actually due. In one case, a landlord refused to refund overpaid charges unless the leaseholder agreed to a lease variation that would make the charge permanent. You have the right to request a detailed breakdown of every line item. If the managing agent’s fees seem high, or if the cleaning and gardening costs are more than the market rate, you can challenge them through the First-tier Tribunal (Property Chamber). Getting a property lawyer to review the service charge clause in your lease before you exchange contracts is a sensible step — it costs a fraction of what you’d pay if you discover a problem later.
How to Check, Challenge, and Plan for Service Charges
Reading the Lease and Understanding Your Liability
The lease sets out exactly what you’re required to pay and how the charge is calculated. Some leases specify a fixed service charge, meaning the amount is set annually and cannot be changed. Others are variable, meaning the landlord can adjust the charge based on actual costs. Look for the clause that describes the “service charge percentage” — this is your share of the total building costs. If the building has 20 flats and you pay 5%, you’re paying a proportionate share. Some leases use a fixed percentage, others use a formula based on floor area. The key figure is the cap — some leases include a maximum annual increase, which protects you from sudden spikes. If you’re unsure about the wording, a tenant and landlord lawyer can explain what the clauses mean in plain English.
Using the Transparency Reforms to Your Advantage
The Leasehold and Freehold Reform Act 2024 introduces standardised service charge statements and makes it easier for leaseholders to challenge unreasonable costs. Landlords must now provide a breakdown of building insurance policies and cannot automatically charge their legal costs to leaseholders when they lose a dispute. This removes what was a significant barrier to challenging poor practice — leaseholders used to risk paying the landlord’s legal bill even if they won. The government consultation running from 4 July 2025 to 26 September 2025 seeks views on mandatory qualifications for managing agents and a reformed Section 20 process. If you’re a leaseholder, submitting your experience to the consultation is a practical way to push for change.
Planning for the Future: Commonhold and Reform
The government’s Commonhold White Paper, published on 3 March 2024, outlines steps to make commonhold the default tenure — meaning you’d own the building jointly with other residents rather than leasing it from a landlord. A draft Leasehold and Commonhold Reform Bill is expected later in 2025. Under commonhold, there is no landlord, no service charge set by a third party, and no ground rent. Residents manage the building themselves and set the budget collectively. While commonhold is still years away from becoming the norm, the direction of travel is clear. If you’re buying an apartment now, look for a building with a well-run residents’ association, a transparent managing agent, and a sinking fund that covers at least the next five years of planned works. Those are the blocks that will hold their value best when the market shifts.

What the Coming Reforms Mean for Your Service Charge Bills
The Leasehold and Freehold Reform Act 2024 has already started to shift the balance of power. Leaseholders can now scrutinise building insurance costs and challenge unreasonable legal fees without risking a huge bill for the landlord’s costs. The next step — mandatory qualifications for managing agents and a streamlined Section 20 process — could make a real difference to the £4,120-a-year London average. The Housing Ombudsman’s case studies show that severe maladministration cases often involve landlords who refused to refund overpaid charges or failed to provide basic breakdowns. The reforms are designed to close those gaps. If you’re a leaseholder, the consultation running until September 2025 is your chance to shape the secondary legislation. For anyone buying an apartment, the simple rule is this: the service charge is not a detail — it’s the deal.
