Service Charges in Commercial Leases: What Tenants Pay and How to Limit Exposure

Think cleaning, security, lighting in common areas, structural repairs, lift maintenance, and building insurance for shared parts.

The landlord incurs these costs and passes them on to tenants as a cost-recovery mechanism, not a revenue stream. Landlords are explicitly prohibited from profiting from service charge contributions and the amount they can recover is limited to the proper and actual cost incurred.

That distinction means a landlord cannot mark up services or use the service charge to subsidise other costs. But it does not mean the charge is capped, predictable, or easy to challenge once you have signed.

Your exposure depends heavily on the type of property you occupy.

Service charge obligations vary significantly across types of commercial property. A small industrial unit with a single occupier may carry minimal or no service charge. It would be a different story if you were to rent an office block, retail centre, or mixed-use development. Properties like those typically come with extensive shared facilities and costs to match.

The table below gives an illustrative sense of how exposure typically scales.

Unlike residential tenants, commercial tenants have no statutory protection on service charges.

In residential property, the Landlord and Tenant Act 1985 governs service charges and gives tenants the right to challenge unreasonable charges. Commercial tenants have no equivalent protection. Commercial property leases have no legislative control over service charges and terms can be freely negotiated.

The primary industry guidance comes from the Royal Institution of Chartered Surveyors (RICS) professional standard on service charges in commercial property, which sets out best practice requirements for RICS members on transparency, apportionment, and dispute resolution. However, the standard only binds landlords who are RICS members. Unless its provisions are written into your lease, you cannot assume they apply.

This risk compounds on a full repairing and insuring lease, where a poorly negotiated service charge clause adds to your existing maintenance obligations. Understanding the full picture before you agree heads of terms is where that protection starts.

How Are Service Charges Calculated and When Do You Pay?

Your share of the bill and when you pay it are both set by the lease, not decided after you move in.

The most common approach is floor-area apportionment, where your share is calculated as a percentage of the total lettable area of the building.

If you occupy 2,000 square feet of a 10,000-square-foot building, your floor-area share is 20% of the total service charge budget. But apportionment methods vary, and the difference between them can shift your contribution considerably.

For example, in a building with a total service charge budget of £60,000, tenants can pay significantly different amounts depending on the apportionment method. The table below gives an illustrative sense of how the same total budget plays out differently depending on the method applied.

The weighted benefit column reflects a scenario where Tenant C occupies an upper floor and makes heavier use of shared services such as lifts.

A "fair proportion" clause sounds reasonable but can be genuinely difficult to challenge once it is in the lease. Insist on a full apportionment matrix before you commit. The RICS Professional Standard requires this of its members, and it is a reasonable request regardless of whether your landlord holds RICS membership.

On payment, the landlord produces a budget based on estimated expenditure, tenants pay quarterly instalments on account, and at the end of the service charge year the landlord reconciles actual expenditure against the estimate, with tenants either making a balancing payment or receiving a credit.

Before signing your lease, always ask for at least two to three years of historic statements. A consistent gap between estimated and actual costs is a reliable sign of poor budgeting, and you will be the one absorbing those balancing charges.

What Should You Negotiate Before Signing?

A cap, express exclusions, independent certification, invoice inspection rights, and RICS incorporation are the core protections worth fighting for.

The lease itself is your only line of defence on commercial service charges.

Here is the core suite of protections worth pushing for:

• A service charge cap. This limits what a landlord can charge you in any given year. Tenants should note that even where a cap exists, it may rise year on year in line with RPI, which can run higher than actual inflation. Model its trajectory over your full lease term before accepting it. Ask your solicitor to benchmark the proposed cap against comparable properties of a similar type and location.
• Express exclusions. Negotiate to exclude costs unrelated to your occupancy: lost income from unlet units, landlord investment costs such as rent collection and letting fees, structural defects, works the landlord caused through negligence, original construction costs, and energy efficiency improvements.
• Independent certification of year-end accounts and the right to inspect invoices. This gives you an objective check on what the landlord actually spends, and proves especially important in complex multi-let developments where individual line items are harder to scrutinise.
• Express incorporation of the RICS Professional Standard. While not legally binding on all landlords, the standard establishes a benchmark that shapes lease negotiations, property management practice, and dispute resolution. An express clause incorporating it by reference makes its requirements contractually binding. Without it, you are relying on your landlord's goodwill and RICS membership status, neither of which is guaranteed.

These terms are negotiable before you sign, but once you do your leverage largely disappears.

This chart uses an illustrative 3% annual RPI increase on a starting cap of £20,000. Actual RPI rates vary, and on a 10-year lease even modest annual increases add up to a materially higher liability than the original cap suggests.

Most leases include a catch-all provision allowing the landlord to charge for additional services. Insist that any such clause links to a reasonableness standard so the landlord cannot introduce extensive or unnecessary works without justification. A vague catch-all clause is one of the most common ways tenants end up paying for works they never expected and cannot challenge.

A poorly negotiated service charge clause can also interact badly with break clauses, creating conditions that are harder to satisfy and more expensive to exit than the headline terms suggested.

How Do You Handle a Service Charge Dispute Without Losing Your Lease?

Pay under protest, keep a paper trail, and use your lease's dispute resolution procedure rather than withholding payment.

Tenants cannot simply refuse to pay service charges, even if they feel they are unfair. This could constitute a breach of the lease and could mean the landlord has the right to forfeit the lease. In some commercial leases, the landlord can exercise that right without prior notice. The dispute may be entirely legitimate, but non-payment puts your occupation at risk regardless.

Raise concerns promptly and in writing. Delays in challenging a charge can signal acceptance, which weakens any subsequent dispute. Query the specific line items, ask for supporting invoices, and keep a clear paper trail from the outset.

Expert determination and mediation are faster, cheaper, and less damaging than litigation.

If the dispute cannot be resolved straight away, one option for the tenant is to pay the service charge under protest. This keeps the door open for the tenant to pursue the dispute while avoiding the inference that, by paying the charge, they accept it as reasonable.

Make the payment while simultaneously writing to the landlord to state clearly that the charge is disputed and that liability is not accepted. The letter should state the amount paid, the date, and make clear that you are paying without admitting liability and that you reserve the right to recover the sum. Keep a copy of that letter.

Most well-drafted commercial leases include a dispute resolution procedure involving expert determination or mediation before any court proceedings. The RICS Professional Standard actively encourages this route. Check at heads of terms stage that your lease includes a clear alternative dispute resolution (ADR) procedure. If it does not, push for one before you sign.

Frequently Asked Questions

What happens to sinking fund contributions if the anticipated works are never carried out, or if a tenant vacates before the works take place?

If the lease is silent on this point, you may have no right to recover contributions you already made, even if the anticipated works never happen or fall outside your lease term. The lease should expressly address whether unused contributions come back to you at lease expiry, what happens to your payments if you vacate early, and who legally owns the accumulated money. Push for funds to be held in a separate designated account on trust for tenants, which offers some protection if the landlord becomes insolvent.

Can service charge terms be negotiated at lease renewal, or only at the start of a lease?

Yes, service charge terms can be negotiated at lease renewal, not only at the start of a lease. If the existing lease has generated disputes or balancing charge surprises, renewal is the moment to address them rather than carry them forward unchanged. Push for tighter exclusions, a cap if one did not exist before, and an express incorporation of the RICS Professional Standard. It is one of the few moments during a tenancy where you have genuine leverage.
