Service Charge Disputes in Commercial Leases: How Tenants Challenge Costs

Last updated: 5 May 2026

Quick answer

A commercial tenant can challenge service-charge costs on three principal grounds: (1) the cost is not within the scope of the service-charge clause as drafted; (2) the cost has been incurred unreasonably or to an unreasonable standard; (3) the cost has been administered improperly (for example, inadequate consultation, failure to provide certified accounts, or breaching the lease's apportionment rules). Unlike residential service charges (governed by the Landlord and Tenant Act 1985 and reviewable by the First-tier Tribunal), commercial service charges are governed almost entirely by the lease terms and general principles of contract. The RICS Service Charges in Commercial Property professional statement, 1st edition (effective 1 April 2019) sets the industry standard for RICS-managed buildings. Disputes are heard in the County Court hearing centre or, by agreement, in arbitration.

How a commercial service charge works

A commercial lease typically contains:

• A schedule of services the landlord agrees to provide
• A service-charge clause requiring the tenant to pay a percentage of those costs
• Provisions for budgeting, on-account payments, year-end reconciliation, and audit

The landlord raises a service charge by:

1. Setting an annual budget
2. Demanding on-account payments quarterly or half-yearly
3. Producing year-end accounts showing actual costs
4. Issuing a balancing demand or credit

The tenant pays the on-account amounts and the year-end balancing item according to the lease's apportionment formula.

The three grounds of challenge

Ground 1 — outside the scope of the clause

The first question is always: does the lease actually require the tenant to pay this cost?

A service-charge clause is read strictly. Costs that fall outside the clause's wording cannot be recovered, even if the landlord considers them reasonable.

Common scope challenges:

• Capital improvements vs repairs — leases distinguishing between maintenance and improvement may exclude the latter
• Specific exclusions — common exclusions for original construction defects, voids, marketing of vacant units
• Time-barred costs — costs from earlier years that were not raised in time under the lease's apportionment provisions
• Costs of disputes — landlord's legal costs of pursuing other tenants are sometimes excluded from service charge

The leading principle: contra proferentem — the clause is read against the landlord (the party that drafted it). Ambiguous wording goes the tenant's way.

Ground 2 — unreasonable in amount or quality

Even where a cost falls within the scope, the tenant can challenge the amount on the basis that:

• The cost is excessive compared with market rates
• The work was procured without competitive tendering
• The standard of work is higher than the lease requires
• The number of suppliers or labour hours is disproportionate

The implied reasonableness obligation comes from common law principles of co-operation between parties under a contract, and from the express words of many service-charge clauses (which often require costs to be "reasonably incurred" or "incurred in a proper and economic manner").

The leading case on the meaning of "reasonable" in service charges is Forcelux v Sweetman [2001] 2 EGLR 173 — the test is "whether a reasonable landlord, in the same position as the actual landlord, would have incurred the same expense in the same circumstances".

In practice, tenants often retain a building surveyor to benchmark costs against industry data (RICS Building Cost Information Service is the standard reference).

Ground 3 — improperly administered

Procedural challenges are often the most fruitful. They can defeat substantively reasonable claims through procedural failure.

Common administrative challenges:

• No certified accounts — most leases require year-end accounts certified by the landlord's accountant; absence is a breach
• No audit access — many leases give the tenant a right to inspect underlying invoices; refusal undermines the demand
• Misallocation between schedules — multi-let buildings often have separate "estate" and "building" schedules; misallocation can affect the apportionment
• Apportionment errors — the lease defines the percentage; using a different percentage breaches the lease
• Late demand — leases often have time limits for raising costs (usually 18-24 months from year end)

A disputed demand on procedural grounds may not eliminate the underlying liability but can delay it and force re-issue.

The RICS Code

The RICS Service Charges in Commercial Property Code is a mandatory professional statement for RICS surveyors managing service charges. Where a building is managed by a RICS member (most professionally-managed commercial property), the Code applies.

The Code requires:

• Annual budget — supplied to tenants before the start of the service charge year
• Quarterly statements — for tenants on quarterly on-account payments
• Annual reconciliation — within 4 months of year end
• Detailed itemised accounts — broken down by cost head
• Apportionment basis disclosure — clear methodology explained
• Fair and reasonable management fees — the Professional Statement requires management fees to reflect actual work done and to be fair and reasonable in the circumstances. Industry practice often expresses fees as a percentage of total service-charge costs; tenants can challenge fees that appear disproportionate to the management work actually undertaken.

A tenant arguing breach of the Code is on strong ground if the lease references the Code or if the Code's presumptive standards reflect industry practice in the relevant year.

Practical steps for a tenant disputing a service charge

Step 1 — request the supporting documents

Most leases give tenants a right of inspection. Use it. Request:

• Itemised year-end accounts
• Underlying invoices for major cost lines
• The annual budget and any revisions
• The apportionment calculation

The landlord must usually respond within 14-28 days depending on the lease. A refusal is itself a procedural ground.

Step 2 — pay under protest, or withhold

Withholding payment is risky — a non-payment leaves the tenant in arrears, exposes the lease to forfeiture (subject to relief from forfeiture) and to interest under the lease.

The safer route is to pay on-account amounts, then dispute the year-end reconciliation or claim repayment on a credit basis. Some leases include "pay-now, dispute-later" provisions that require payment first; these are enforceable.

For a substantive challenge, pay under written protest, reserving rights, while the dispute is resolved.

Step 3 — write a substantive challenge letter

A good service-charge challenge letter:

• Identifies each disputed item by line
• States which of the three grounds applies
• References the specific lease clause and the alleged breach
• Quantifies the disputed amount
• Proposes a way forward (audit, mediation, expert determination)

Step 4 — escalate proportionately

Most service-charge disputes resolve through correspondence, with adjustments at year-end reconciliation. Where they do not, options are:

• Mediation — a quick, informal route, particularly where the relationship is ongoing
• Expert determination — both sides agree to an independent surveyor's view
• Arbitration — where the lease provides for it
• County Court / High Court litigation — where amounts justify the cost

The county court hearing centre is the usual forum. Higher-value disputes (£500,000+) may go to the High Court Property, Trusts and Probate List.

Special features of multi-let buildings

In multi-let buildings, additional complications arise:

• Service-charge schedules — different parts of the building may have different schedules (e.g. "estate" schedule for shared services, "building" schedule for building-specific services)
• Anchor-tenant carve-outs — anchor tenants in shopping centres often have heavily-modified service-charge clauses
• Capping arrangements — some tenants have negotiated caps on annual increases
• Voids contributions — where a unit is vacant, who pays the void's share?

A tenant in a multi-let building should check:

• Which schedule applies to them
• Whether other tenants have caps or carve-outs that shift cost onto them
• Whether voids are landlord-funded or socialised across paying tenants

Bundle preparation for a service-charge trial

A service-charge trial bundle commonly contains:

• Section A: Pleadings (Particulars of Claim, Defence, replies)
• Section B: Lease and side letters
• Section C: Service-charge demands and supporting accounts (year-by-year)
• Section D: Witness statements
• Section E: Surveyor's report (if scope of clause or reasonableness is in issue)
• Section F: Building cost benchmark data
• Section G: Inter-party correspondence
• Section H: Authorities

BundleCreator's Commercial Property template structures the bundle in the order trial counsel expect, with each year's service-charge demands and accounts grouped chronologically. Pagination, hyperlinked index, OCR, and bookmarks are produced automatically. A bundle that takes 8-15 hours to assemble manually is usually finished in around 30 minutes.

Frequently asked questions

Can I withhold all service charge during a dispute?

Risky — and often impermissible under the lease. Most commercial leases have express words requiring payment without set-off. Even where set-off is available, withholding triggers interest and possible forfeiture proceedings. Pay under protest and dispute through correspondence and accounting adjustments.

What is the time limit for challenging an old service-charge year?

Two answers. Under the lease, often 18-24 months from year-end (the lease's own provisions). Under general contract law, six years from the date of demand under section 5 of the Limitation Act 1980.

Is the landlord's management fee always recoverable?

Only if the lease allows it. Most modern leases include management fees in the recoverable cost; older leases sometimes do not. The RICS Code's 10% presumptive cap on management fees is often exceeded — and the excess is sometimes vulnerable to challenge.

What about "improvements" charged as repairs?

A classic dispute. The general rule: maintenance and repair are recoverable; improvements (works that put the building in a better condition than originally required) are not, unless the lease expressly allows.

The line is fact-sensitive. Replacing a single boiler is typically maintenance. Re-cladding a tower is typically improvement. Mid-cases require detailed expert evidence.

Can I sue for repayment of past overcharges?

Yes, where:

• The overcharge was paid within six years (Limitation Act 1980, section 5)
• The lease's account-finalisation provisions have not closed the year (some leases include "binding" provisions requiring objection within a window)
• You can prove the overcharge

Repayment claims for past years are common in tenant exits and lease renewals — a tenant about to sign a new lease has leverage to negotiate past corrections.

What if the landlord refuses to provide audit access?

Most leases give a right of inspection. Refusing inspection is a breach. The tenant can apply to the County Court for a specific performance order, though most disputes resolve once the threat of court action is made and the landlord realises the tenant is serious.
