Service charges on commercial property can easily add thousands of pounds a year to your overheads, yet many tenants only realise what they’ve signed up for when the first reconciliation bill lands. That gap between expectation and reality is where cash flow gets squeezed and disputes begin. I’ve watched this pattern play out across dozens of lease negotiations, and the single biggest factor that determines whether a tenant ends up paying fairly or overpaying is what they did — or didn’t do — before signing.
Service charges aren’t rent, but they behave like a second rent that can change year to year. They cover the cost of running shared areas — cleaning corridors, maintaining lifts, lighting car parks, and insuring the building. The problem is that most leases define these charges in broad terms, leaving plenty of room for interpretation when the bill arrives. If you’re looking at a commercial space right now, the first thing I’d do is ask for a detailed breakdown of the service charge budget before you agree to anything. Here’s what you actually need to know.
How service charges are calculated and what they cover
The most important thing to understand is that there’s no single way service charges are worked out. Your lease will specify one of three methods. A fixed percentage means you pay a set share, often based on the square footage your business occupies. A pro-rata basis splits costs among all tenants according to the space they lease. A fair and reasonable apportionment means the landlord works out who benefits from each service and divides costs accordingly — so only upper-floor tenants might pay for lift maintenance, for example. Most leases will specify when and how service charges are reviewed and paid, usually quarterly or annually.
What can you actually be charged for? The list is long but standard: cleaning and maintaining shared spaces like corridors, lifts, and receptions; building security, CCTV, and entry systems; heating, lighting, and utilities for common areas; repairs and upkeep of the main structure, roof, or external walls; gardening and grounds maintenance; management fees for running the building; and insurance if it covers the whole property. The catch is that some landlords try to add new services — like enhanced security or upgrades — that weren’t agreed in the original lease. Make sure every service is clearly listed upfront. If you’re unsure about any of this, speaking with a tenant landlord lawyer before you sign can save you a lot of headache later.
Why getting service charges wrong hurts your business
Unexpected service charge increases can hit your cash flow hard. If you’ve budgeted for a fixed amount and the reconciliation bill arrives showing you owe an extra £2,000, that’s money you weren’t planning to spend. Over time, these costs can seriously affect your profitability. The impact on financial planning is one of the most common reasons tenants end up in disputes with their landlords.
Consider this scenario: you run a small retail business in a shared building with five other tenants. The landlord decides to upgrade the lift system and replace the roof. If your lease doesn’t cap service charges, you could be on the hook for a significant portion of those costs — even if you’re on the ground floor and never use the lift. That’s not unusual, and it’s exactly the kind of situation where knowing your rights matters.
What I tend to notice is that tenants who negotiate a service charge cap or an annual review clause before signing rarely regret it. Those who skip that step often end up in a dispute within the first two years. The difference is usually a few lines in the lease that take ten minutes to discuss.
If you’re in a rural area, the dynamics can be different — fewer tenants mean a larger share of costs for you. I’d recommend reading our advice on rural commercial leases if that applies to your situation.
Where tenants get caught out
The most common mistakes I see aren’t about the big things — they’re about the details that seem minor at the time. Here are the ones that cause the most trouble.
Signing without a service charge cap
If your lease has no cap, charges can jump dramatically from one year to the next. A cap — usually a fixed percentage increase or a limit tied to inflation — gives you predictability. Without one, you’re exposed to whatever the landlord decides to spend. Negotiate for a cap or at least for annual reviews so you’re not caught off guard. If the landlord refuses, that’s a red flag worth noting.
Not checking who chooses the contractors
If the landlord picks expensive contractors, your costs go up. Some leases give tenants the right to review supplier costs or at least be notified of major changes. Ask for this before you sign. A simple clause saying the landlord must use “competitive tenders” for work over a certain value can save thousands.
Ignoring the sinking fund
Some leases require you to pay into a sinking fund for future major repairs like roof replacements or lift overhauls. Make sure you understand how the fund is managed, what happens to your contributions if you leave, and whether you’ll get a refund. Without clarity, you could be paying for repairs that benefit the next tenant, not you.
Overlooking the reconciliation process
The year-end reconciliation is where most disputes start. The landlord estimates costs at the start of the year, you pay in instalments, and then actual costs are tallied. If the estimate was too high, you should get a refund. If it was too low, you pay the difference. The problem is that some landlords don’t provide proper breakdowns or supporting documents. You have the right to ask for an annual statement and evidence of costs. If you don’t get it, that’s a warning sign. A property lawyer can help you challenge unreasonable demands.

Managing service charges isn’t complicated once you know what to look for. Here’s a practical guide to getting it right from the start.
Review the lease before you sign
Your lease is the single most important document. It sets out what the landlord can charge and what they can’t. Never assume something is included or capped — always check the contract. Look for the service charge clause and note the calculation method, the review frequency, and whether there’s a cap. If the lease refers to the RICS code of practice, that’s a good sign — it sets standards for fair and transparent service charges. While not a law, it’s treated as the industry gold standard. If the lease doesn’t mention it, ask why.
Ask for a detailed budget and annual accounts
Before you agree to anything, ask for a detailed breakdown of what’s included in the service charge. The landlord should provide a budget at the start of the year showing estimated costs. At year end, you’re entitled to an annual statement and evidence of costs incurred. If the landlord refuses, that’s a red flag. Under the new rules from the Leasehold and Freehold Reform Act 2024, landlords must issue service charge demands in a prescribed format that clearly sets out the total amount, the period it covers, payment deadlines, and a summary of your rights. If a demand doesn’t follow the format, it may be unenforceable.
Negotiate for transparency and a cap
You can negotiate for more transparency or even a service charge cap if you’re worried about future increases. A cap limits how much the charge can rise each year, usually to a fixed percentage or in line with inflation. You can also ask for the right to review supplier costs or to be notified of major changes. If the landlord chooses expensive contractors, your costs can soar. A clause requiring competitive tenders for work over a certain value gives you some control. If you’re negotiating a lease for a distribution centre, our tips for distribution centre leases cover additional considerations.
Understand the reconciliation process and your rights
The reconciliation process works like this: the landlord estimates the year’s total service costs and sends all tenants a budget. Throughout the year, you pay your share in monthly or quarterly instalments. At year end, actual costs are tallied. If the estimate was too high, you get a refund or credit. If costs were higher, you pay the difference. You have the right to challenge unreasonable charges. The law requires that only reasonable and foreseeable expenses can be passed on to tenants — not costs for major improvements or unexpected upgrades unless specifically allowed in the lease. If you think you’re being overcharged, you can dispute the charges through court or independent mediation. A small claims lawyer can guide you through the process if it comes to that.
- 1Get the budget in writingAsk for the landlord’s estimated service charge budget for the coming year. Review it line by line and question anything that seems high or vague.
- 2Check the reconciliation statementAt year end, compare actual costs against the budget. If the landlord can’t provide receipts or invoices, you have grounds to challenge the charges.
- 3Know the 18-month deadlineIf the landlord demands payment for costs older than 18 months, check whether they served the required notice. If not, the demand is invalid.
- 4Dispute in writingIf you believe you’re being overcharged, write to the landlord explaining why. Keep copies of everything. If they don’t respond, consider mediation or legal advice.
What’s changing under the new rules
The Leasehold and Freehold Reform Act 2024 and the updated RICS Service Charge Code 2025 mark the biggest overhaul of service charge regulation in decades. For commercial tenants, the key changes include mandatory standardised service charge demands, annual reporting requirements for buildings with four or more dwellings, and enhanced rights to access supporting documents like contracts, invoices, and insurance policies. Landlords must also disclose any commission they receive on building insurance — if they don’t, they cannot recover the premium through the service charge. Tribunal and court costs can no longer be passed on to tenants unless a tribunal specifically orders otherwise. These changes give you more leverage than ever before.
