I’ve seen too many small business owners sign a lease for a commercial space only to be blindsided months later by a bill for thousands of pounds in service charges they never expected. According to research on commercial property service charges, unexpectedly high bills are one of the most common pain points for tenants, especially in older buildings or where major works are planned. That figure matters because it means the rent you negotiated is only half the story — the other half is buried in the small print of your lease.
I cover commercial property leasing for a living, and the question I hear most often from tenants is simple: “What am I actually paying for, and can they charge me more next year?” The answer depends entirely on how your lease is written. If you’re looking at a multi-tenant office, a retail unit in a parade, or a space on an industrial estate, you will almost certainly face a service charge. Understanding surveyor fees when renting commercial space is one piece of the puzzle, but the service charge is where most of the financial surprises live. Here’s what you actually need to know.
What a commercial service charge actually covers
The real risk isn’t the charge itself — it’s the vague lease wording that gives the landlord wide discretion to include additional costs. A commercial service charge is a payment to the landlord or managing agent covering the cost of maintaining and managing shared parts of a property. That sounds straightforward until you realise the list of what counts as “shared” can stretch much further than you’d expect.
In multi-tenant offices, retail parades, shopping centres, industrial estates, and serviced buildings, service charges typically cover cleaning and maintenance of common areas, repairs to shared parts, landscaping, security, CCTV, concierge, lift servicing, waste management, building management fees, and insurance administration. Structural repairs can be very expensive and may be included too. Major works like roof replacement or external redecorations may also fall under the charge, and a sinking fund or reserve fund might exist to collect money each year for those future large repairs. What I’d tell any tenant is this: the difference between a manageable charge and a nightmare is how clearly the lease separates day-to-day maintenance from big capital expenditure. Tenant service charge rules in the UK vary enormously depending on how your lease is drafted, so don’t assume standard practice applies.
Why the cost can spiral without warning
Commercial service charges carry no statutory cap in the UK. That single fact changes everything. Unlike residential property, where the Landlord and Tenant Act 1985 gives tenants the right to challenge unreasonable charges, commercial leases have no legislative control over service charges. The primary industry guidance comes from the RICS professional standard on service charges in commercial property, but that standard only binds landlords who are RICS members.
Consider a small business renting 2,000 square feet in a 10,000-square-foot building with a total service charge budget of £60,000. Under floor-area apportionment, that tenant pays £12,000. Under equal division across three tenants, they also pay £12,000. But under weighted benefit, the same tenant could pay £5,000 while another tenant in the same building pays £13,000. The apportionment method baked into your lease determines your share, and a “fair proportion” clause can be genuinely difficult to challenge once it is in the lease. I’ve noticed that tenants rarely ask for the apportionment matrix before signing, and that’s where the trouble starts.
What I’d do in your position is ask for at least two to three years of historic service charge statements before signing anything. A consistent gap between estimated and actual costs is a reliable sign of poor budgeting. And if the lease includes a catch-all provision allowing the landlord to charge for additional services — which most do — that vague wording is one of the most common ways tenants end up paying for works they never expected and cannot challenge. Tenant service charge benchmarking can help you compare costs across similar properties, giving you leverage before you sign.
Where tenants get caught out
The mistakes I see repeat themselves across leases, sectors, and regions. Here are the patterns that cost tenants the most.
Signing without historic data
Without a full apportionment matrix before signing, tenants commit to costs they cannot yet quantify. The RICS Professional Standard requires its members to provide an apportionment matrix with a breakdown of total costs and weighting between occupiers, but if your landlord isn’t an RICS member, you have no right to that information unless the lease says so. Ask for at least two to three years of historic statements before signing. If the landlord refuses, that is itself a red flag.
Withholding disputed charges instead of paying under protest
Tenants who withhold disputed service charges risk forfeiting their lease. The legally prudent alternative is the pay under protest strategy: you pay the charge but formally state in writing that you dispute it and intend to challenge it. This keeps your lease intact while preserving your right to seek a refund or adjustment later. If you need legal guidance on this process, speaking with a tenant landlord lawyer can clarify your specific position before you take any step that could jeopardise your tenancy.
Ignoring the interaction with break clauses
A poorly negotiated service charge clause can interact badly with break clauses, creating conditions that are harder to satisfy and more expensive to exit. If your break clause requires all sums due under the lease to be paid, and the landlord claims outstanding service charges, you may find yourself unable to exercise the break without paying disputed amounts first. Check the wording of both clauses together before you sign.
Paying for costs that should be excluded
Tenants should negotiate to exclude costs unrelated to their occupancy: lost income from unlet units, landlord investment costs, structural defects, works caused by landlord negligence, original construction costs, and energy efficiency improvements. Under the new RICS standard, landlord investment costs including asset management, rent collection, and costs relating to enhancing the landlord’s reversionary interest must not be recovered through the service charge. Void property costs, initial capital costs, future redevelopment costs, and negligence-related costs are also excluded. But if the lease doesn’t reflect these exclusions, the RICS standard cannot override it.

| Cost type | Can it be recovered? | Key change from 2025 |
|---|---|---|
| Landlord investment costs | No | Explicitly excluded under new standard |
| Void property costs | No | Rates, insurance, marketing of empty units excluded |
| Initial capital costs | No (unless agreed) | Original fit-out and new installations excluded |
| Negligence-related costs | No | Poor maintenance costs cannot be passed on |
| ESG expenditure | Only if genuine service | All other ESG initiatives funded by landlord |
What I’d flag as most important here is the management fee change. Under the new RICS standard, management fees may no longer be based on a percentage of the budgeted or actual service charge. They should now be fixed at the start of a service charge year. That single change removes the landlord’s incentive to inflate the budget, because a percentage-based fee rises when the budget rises. If your lease predates this standard, check whether the management fee structure still follows the old model.

Negotiate a service charge cap into your lease
A service charge cap limits what the landlord can charge in any given year. Caps are often the most helpful protection for small businesses, giving certainty and limiting exposure to sudden spikes. Even where a cap exists, it may rise year on year in line with RPI, which can run higher than actual inflation, so negotiate the index reference carefully. A fixed service charge — a set amount that does not change during a period or only changes in line with a defined method — offers even more predictability. If the landlord pushes back on a cap, ask for a “collar” instead, which sets a minimum and maximum amount payable regardless of costs.
Get the RICS standard written into your lease
Express incorporation of the RICS Professional Standard makes its requirements contractually binding, even if your landlord is not an RICS member. The updated standard, which came into force on 31 December 2025, introduces the most significant shift in service charge governance in nearly a decade. It tightens controls, raises transparency expectations, and reshapes service charge negotiations. Landlords must now issue service charge budgets to tenants at least one month before the start of the service charge year, and year-end accounts and reconciliations must be provided within four months of the end of the service charge year. Any delay must be accompanied by an explanation. Having these timelines in your lease gives you enforceable rights.
Review the apportionment method and exclusions
The most common approach to calculating a tenant’s share is floor-area apportionment, but equal division and weighted benefit are also used. Ask for the full apportionment matrix before signing. Then negotiate to exclude specific costs: lost income from unlet units, landlord investment costs, structural defects, works caused by landlord negligence, original construction costs, and energy efficiency improvements. Under the new RICS standard, void property costs including rates, insurance and services attributable to empty units, and the marketing of empty units must not be recovered through the service charge. Initial capital costs such as original fit-out, installation of new plant or equipment, or improvement works that go beyond repair or replacement must not be recovered unless expressly justified and agreed. Future redevelopment costs including feasibility studies and project planning are also excluded. Make sure your lease language matches these exclusions.
- 1Request historic statementsAsk for at least two to three years of service charge statements before signing. A consistent gap between estimated and actual costs signals poor budgeting.
- 2Check the apportionment matrixConfirm how your share is calculated — floor area, equal division, or weighted benefit. The same building can produce very different bills depending on the method.
- 3Negotiate exclusions and a capExclude costs unrelated to your occupancy and negotiate a service charge cap or fixed charge. Incorporate the RICS standard into the lease for binding protection.
- 4Audit year-end statementsRequest independent certification of year-end accounts and the right to inspect invoices. This gives an objective check on what the landlord actually spends.
Understand the new rules on ESG and commission
Under the updated RICS standard, landlords and managers should only include Environmental, Social, and Governance (ESG) expenditure where it constitutes a genuine service. All other ESG initiatives must be funded by the landlord. Any commission, rebates, or other payments received by the landlord or its manager should be declared in the service charge accounts, and landlords should retain commission only where this is reasonable to reflect work undertaken. Interest on service charge monies must be credited to the service charge, after bank charges and tax have been deducted. These provisions matter because they prevent the landlord from using the service charge as a profit centre — something the law already prohibits, but which the new standard makes harder to hide.
