If you rent commercial space in the UK, the service charge is often the part of the lease that causes the most confusion and, frankly, the most friction. I’ve seen tenants sign leases assuming the service charge is a fixed, predictable cost, only to be hit with unexpected bills for things like empty unit rates or major building improvements. The reality is that service charges have long been a grey area, but that is changing. A new professional standard from the Royal Institution of Chartered Surveyors (RICS) came into force on 31 December 2025, and it represents the most significant shift in how these charges are managed in nearly a decade. This isn’t just a minor update; it changes the rules on timing, transparency, and what costs can actually be passed on to you. Here’s what you actually need to know.
If you are negotiating a new lease or reviewing an existing one, this new standard gives you real leverage. It sets a benchmark for what is considered reasonable, even though it doesn’t override your lease terms. My advice is to use this as a checklist when you review your service charge provisions. For example, you can now expect budgets a month in advance and final accounts within four months of the year-end. If your landlord is RICS-regulated, they must comply. If they aren’t, the standard still serves as a powerful reference point in negotiations. For a broader look at what to consider when choosing a property, you might find our guide on finding the perfect commercial space to rent in the UK helpful. And if you’re dealing with a complex lease and need clarity on what you’re being charged for, speaking with a tenant landlord lawyer can be a smart first step.
What the New RICS Service Charge Standard Actually Means for You
The core idea behind the updated standard is simple: make service charges fairer and more transparent. It’s not a law, but it is compulsory for all RICS-accredited professionals. What I find most useful about it is that it gives tenants a clear, industry-backed position to argue from. The lease is still king, but the standard is now the recognised indicator of what is reasonable. So, if your lease is vague, the standard fills the gap.
One of the biggest changes is around timing. Previously, it wasn’t uncommon for year-end reconciliations to arrive months late, leaving tenants in the dark about their actual costs. Now, landlords must provide budgets at least one month before the service charge year begins, and final accounts within four months of the year ending. Any delay must come with an explanation. This gives you much greater certainty when planning your business finances. It also means you can challenge a reconciliation that arrives late without a good reason.

Why the New Rules on Non-Recoverable Costs Matter Most
The most practical change for tenants is the clear list of costs that should not be recovered through the service charge. This is where I’ve seen the biggest disputes arise. Landlords used to try to pass on costs that were really their own responsibility. The new standard explicitly bans the recovery of landlord investment costs, including asset management and rent collection. It also bans void property costs — that means you shouldn’t be paying for the rates, insurance, or services on empty units in your building. This alone can save a tenant thousands of pounds a year.
Consider this scenario: you are in a multi-let office building, and two units have been empty for six months. Under the old, less clear rules, the landlord might have apportioned those empty unit costs across the remaining tenants. Under the new standard, that is explicitly not allowed. The landlord must bear those costs themselves. The same applies to initial capital costs, like the original fit-out of the building or installing new plant equipment. If it’s an improvement that goes beyond repair or replacement, it shouldn’t be on your bill unless it’s been expressly justified and agreed in the lease. This is a significant shift that directly protects your bottom line. If you’re looking at a property with high vacancy rates, this is a critical point to raise during negotiations.

Where Tenants Commonly Get Tripped Up on Service Charges
Even with better rules, mistakes happen. The most common one I see is tenants not checking the apportionment matrix. The new standard requires landlords to provide a breakdown of total costs and how they are weighted between occupiers. If you don’t ask for this, you might be paying a disproportionate share. Another frequent error is accepting a management fee based on a percentage of the total service charge. The standard now says fees must be fixed at the start of the year. If your lease still has a percentage-based fee, you have grounds to challenge it.
Ignoring the Apportionment Matrix
Many tenants simply accept the service charge figure without understanding how it’s split. The new standard mandates an apportionment matrix that shows the weighting between occupiers. If you are in a smaller unit but paying a higher proportion than a larger neighbour, you need to know. Ask for this matrix during heads of terms. It’s a simple request that can prevent years of overpayment.
Accepting Percentage-Based Management Fees
Management fees calculated as a percentage of the total service charge create a perverse incentive for the landlord to increase costs. The new standard bans this practice. Fees must now be fixed at the start of the service charge year. If your lease still has a percentage clause, you should negotiate to change it to a fixed fee. This gives you cost certainty and removes the conflict of interest.
Overlooking Commission and Rebates
Landlords often receive commission on buildings insurance or rebates from contractors. Under the new standard, these must be declared in the service charge accounts. The landlord should only retain commission where it is reasonable to reflect work undertaken. If you suspect your landlord is pocketing undisclosed commissions, you can request to see the accounts. This is a powerful tool for ensuring you aren’t being overcharged.
Failing to Challenge Late Reconciliations
If your landlord fails to provide the year-end reconciliation within four months, they must provide an explanation. If they don’t, you have a legitimate basis to question the entire charge. I’ve seen tenants simply pay a late reconciliation without question, assuming it’s correct. Don’t. Use the standard’s timeline as a shield. A late account is a red flag that the process may not be well-managed.

Knowing the rules is one thing; using them is another. Here is a step-by-step approach to protecting your business from unfair service charges. The key is to be proactive, not reactive. Start during lease negotiations, not after you’ve signed.
Request the Apportionment Matrix During Heads of Terms
Before you sign anything, ask the landlord for the apportionment matrix. This document shows how total costs are split between tenants. It should be provided with the budget. If the landlord hesitates, that’s a red flag. You need to see this to ensure you are being charged a fair share. If the matrix seems off, you can negotiate a different weighting or a cap on your total service charge liability. This is your best chance to set a fair baseline.
Scrutinise the Budget for Banned Costs
Once you have the budget, go through it line by line. Look for any costs that fall into the banned categories: landlord investment costs, void costs, initial capital costs, or negligence-related costs. If you see something like “asset management fee” or “marketing of empty units,” flag it immediately. The standard is clear that these should not be recovered. If the landlord insists, you have a strong argument based on industry best practice. For a more detailed look at the legal side of these negotiations, our article on commercial property for startups in the UK covers some of the brutal truths about lease terms.
Confirm the Management Fee Is Fixed
Check the lease or the budget to see how the management fee is calculated. If it’s a percentage of the total service charge, you need to negotiate a change to a fixed fee. The new standard says fees should be fixed at the start of the year. A fixed fee gives you certainty and removes the landlord’s incentive to inflate costs. If the landlord refuses, ask for a clear justification in writing. This is a non-negotiable point under best practice.
Use Alternative Dispute Resolution for Disputes
If a dispute arises over the service charge, the standard encourages using Alternative Dispute Resolution (ADR) before going to court. ADR is often faster and cheaper. It includes mediation or arbitration. If you have a disagreement about a specific cost, suggest ADR in writing. This shows you are acting reasonably and can help resolve the issue without the expense of litigation. If you need professional guidance on the legal merits of your case, consulting a business lawyer can clarify your options.
Plan for the Ban on Upward-Only Rent Reviews
While not directly about service charges, the proposed ban on upward-only rent reviews in new and renewal commercial leases is a major development. The government’s English Devolution and Community Empowerment Bill, published in July 2025, includes this proposal. If enacted, it would mean your rent could go down as well as up at review. This is a significant shift in bargaining power. When negotiating a new lease, be aware that this change may be law by late 2026 or 2027. It could affect how you structure your rent review clauses. For now, it’s something to watch closely, as it will fundamentally change the economics of commercial leasing.
