Beyond the Annual Figure: A Flat Buyer's Service Charge Evidence Review for 2026

Service charges are often presented as a clean annual figure in a sales pack. In a flat purchase, that figure is only a headline. The substance lies in the accounts behind it, the money set aside for future works and the lease that governs what can be charged. For buyers approaching exchange in 2026, a structured review is less about suspicion than about evidence. At Trident House, we suggest treating the service charge as three prongs of one question: what has been spent, what has been saved and what has been promised.
First prong: the accounts and the current budget
Ask the managing agent for the last three years of certified service charge accounts, the current year budget and the latest reconciliation. Read the notes as well as the totals. Look for the difference between budgeted and actual expenditure, any deficit carried forward, the treatment of major works and the apportionment between flats. A charge that looks modest may simply reflect deferred maintenance; a charge that looks high may include services a buyer does not need or historic debt being recovered.
Useful questions include: what was actually spent against budget in each of the last three years? Is there a balancing charge or credit pending? How are costs apportioned between units? Are any flats in arrears, and how does that affect cash flow? Are there current or anticipated disputes? What major works are planned in the next three years, and has consultation under Section 20 of the Landlord and Tenant Act 1985 begun?
The management pack is a summary, not a substitute for the underlying documents. If the agent cannot explain a movement in the accounts, ask for the invoice or ledger entry. A buyer should not have to accept an annual figure without knowing what sits behind it.
Second prong: the reserve fund and planned maintenance
A reserve fund separates day-to-day running costs from future capital works. Ask for the reserve balance, the date it was last assessed, any reserve study or planned maintenance schedule and the assumptions behind it. Buildings with lifts, flat roofs, balconies, rendered facades, communal heating or fire safety systems can require substantial reserves. A healthy-looking balance may be inadequate if a roof replacement or facade remediation is due within a few years.
Ask whether the reserve is held in a separate designated account, whether it is audited and whether the lease permits the landlord to collect for future works. Find out whether special levies have been raised in recent years and whether any are expected. Check the buildings insurance premium and claims history as part of the same conversation; insurance and reserve planning are closely linked.
A low reserve does not automatically make a flat unsaleable, but it changes the risk and the negotiation. The buyer is not only purchasing the flat; they are buying into a shared financial arrangement that may require further contributions.
Third prong: the lease and the legal framework
The lease defines what can be charged and how. Your solicitor should review the service charge clause, any cap or fixed charge, the estimate and balancing mechanism, the reserve provisions and the insurance obligations. They should also check whether separate estate charges apply, whether the lease includes onerous covenants and whether consent is needed for letting, alterations or home working.
Ask specifically: is the service charge variable or fixed? Is there a cap? Who insures the building, and what is the rebuilding obligation? Are there separate charges for an estate or shared facilities? What is the ground rent, and does it contain review provisions? How long is the lease, and is a deed of variation needed? Has the freeholder or management company changed recently? Is there a right to manage company, and are the accounts transparent?
A solicitor should also explain the buyer's ability to challenge unreasonable service charges at the First-tier Tribunal and the practical consequences of doing so. Legal rights are valuable, but they are not a substitute for evidence before exchange.
Bringing the three prongs together
The accounts, the reserve and the lease should tell a consistent story. If they do not, ask why. A low annual charge with no reserve and vague major works is not necessarily good value. A high charge with a well-funded reserve and a clear maintenance plan may be more predictable. Red flags include missing accounts, repeated special levies, no reserve study, unexplained major works, short lease terms and clauses that allow wide discretion without accountability.
Not every issue is a deal-breaker. Some can be priced, negotiated or resolved through a retention held by the solicitor. The important step is to instruct a solicitor early enough to review the pack properly and to put questions in writing to the managing agent. The service charge is a forward liability, not a monthly extra. Trident House's view is simple: buy the evidence, not just the annual figure.
