Over the past few years, I’ve watched the commercial property landscape shift in ways that catch even experienced business owners off guard. The rules around leases are changing faster than many people realise, and the old assumptions about what a lease means no longer hold. If you’re running a business in the UK and you rent your premises, the decisions you make about your lease right now could lock you into terms that look very different in a year or two.
That’s not speculation. The legislative calendar for 2026 is packed with changes that directly affect how leases are written, how rent is reviewed, and what happens when a lease ends. The government’s English Devolution and Community Empowerment Bill, published in July 2025, includes a proposed ban on upwards-only rent reviews in new commercial leases. The Law Commission has provisionally concluded that the minimum term for protected business tenancies should increase from six months to two years. And the updated RICS Professional Standard on service charges in commercial property took effect on 31 December 2025. These aren’t distant possibilities — they’re happening now. Here’s what you actually need to know.
What a private sector lease actually means in 2026
The most important thing to understand is that a lease is no longer just a document that says how much rent you pay and for how long. It’s now a contract that sits inside a rapidly changing legal framework. The way rent is calculated is being rethought. The protections you have when your lease ends are being rewritten. And the information your landlord must hold about the property is becoming public.
What I tend to notice is that most business owners focus on the headline rent figure and the lease length, then sign and move on. That approach worked when the rules were stable. It doesn’t work now. The service charge code, for example, is compulsory for all RICS-accredited professionals from 31 December 2025. That means your surveyor or managing agent must follow it. If they don’t, you have grounds to challenge them. But you need to know the code exists and what it requires.
Why these changes matter for your business
Let me give you a concrete scenario. Imagine you run a small retail business and your current lease has an upwards-only rent review clause. Under the proposed ban, when you renew that lease, the clause becomes unenforceable. That sounds like good news — and it is — but it also means your landlord may try to compensate by setting a higher starting rent or shorter lease term. The Bill continues to progress through Parliament and could become law in late 2026 or 2027. You need to know where your lease sits in that timeline.
Then there’s the service charge. The updated RICS code doesn’t override your lease terms, but it sets industry benchmarks. If your landlord charges you for lift maintenance or cleaning without providing a proper breakdown, the code gives you a reference point to push back. I’ve seen tenants pay thousands in unexplained service charges simply because they didn’t know they could ask for a detailed account. The code changes that.
And the PRS database, while aimed at residential landlords, signals a broader shift toward transparency. If your commercial landlord also owns residential properties, the database will require them to register safety and property data from late 2026. That same data discipline is likely to influence how they manage commercial properties too. My first move would be to check whether your landlord is already preparing for this — if they’re not, it tells you something about their approach to compliance.
Where people go wrong with private sector leases
The most common mistake I see is treating the lease as a fixed document that can’t be negotiated. That’s never been true, but it’s especially false now. Here are the specific errors that cost businesses money.
Ignoring the service charge breakdown
Many tenants accept the service charge figure on the lease without asking for a breakdown. The updated RICS code, effective from 31 December 2025, requires RICS professionals to follow specific standards when preparing service charge accounts. If your managing agent is RICS-accredited, you can request a detailed breakdown and challenge anything that doesn’t match the code. Understanding what you’re paying for is the first step to controlling it.
Assuming security of tenure is automatic
Under the Landlord and Tenant Act 1954, most business tenants have the right to renew their lease when it ends. But that protection can be contracted out — and many leases do exactly that. The Law Commission has provisionally concluded that the current model for contracting out is the right one, but it also proposes increasing the minimum term for protected tenancies from six months to two years. If you’re on a short-term lease under two years and the change goes through, you lose statutory protection entirely. Check your lease now, not when it’s about to expire.
Overlooking the rent review clause
Upwards-only rent reviews are common in commercial leases. The proposed ban would make them unenforceable in new and renewal leases, but existing leases are not affected. If you’re negotiating a renewal, the landlord may try to include an upwards-only clause before the ban takes effect. Don’t let them. Use the proposed legislation as leverage to negotiate a review that allows rent to go down as well as up.
| Reform | Current position | Proposed change |
|---|---|---|
| Upwards-only rent reviews | Common in commercial leases | Banned in new and renewal leases |
| Minimum lease term (protected) | 6 months | 2 years (provisional) |
| Service charge standards | Voluntary guidance | Compulsory for RICS professionals |
| PRS database | No central register | Mandatory registration from late 2026 |
Not preparing for the PRS database
Even if you’re a commercial tenant, the PRS database rollout from late 2026 affects you indirectly. Your landlord will need to register property details, safety certificates, and occupancy information. If they can’t produce those documents, it becomes a database accuracy issue visible to councils. That could delay renewals or trigger inspections. Ask your landlord now whether they have gas safety, electrical safety, and EPC documents ready. If they don’t, you know where the gaps are.

How to approach your next lease negotiation
Whether you’re signing a new lease or renewing an existing one, the same principles apply. You need to know what’s changing, what’s negotiable, and where the risks are. Here’s how to do it.
Review your rent review clause before you sign
If the lease contains an upwards-only rent review clause, ask for it to be removed or replaced with a review that allows rent to go down. The proposed ban gives you a strong argument: why lock into a clause that will soon be unenforceable? If the landlord refuses, consider whether the property is worth the long-term cost. A clear understanding of notice periods and review mechanisms will help you plan your exit if needed.
Demand a detailed service charge schedule
Under the updated RICS code, you’re entitled to a breakdown of what you’re paying for. Ask for it in writing before you sign. If the landlord can’t provide one, that’s a red flag. If they can, check whether the charges match the code’s benchmarks. Common items like lift maintenance, cleaning, and building insurance should be itemised separately. If you’re in a multi-let building, ask how the costs are apportioned. A reserve fund for major works should also be clearly documented.
Check your security of tenure status
Look at the lease to see whether it contracts out of the Landlord and Tenant Act 1954. If it does, you have no automatic right to renew. That matters more now because the Law Commission proposes increasing the minimum term for protected tenancies to two years. If you’re on a short-term lease that’s contracted out, you could find yourself with no protection and a shorter renewal window. If you’re unsure, ask a tenant landlord lawyer to review the document before you sign.
Prepare for the PRS database requirements
Even though the database is aimed at residential landlords, the same data discipline applies to commercial properties. Start gathering your property documents now: gas safety certificates, electrical installation condition reports, and the EPC. If your landlord can’t produce these, it’s a problem. If they can, store them in a consistent format. A fireproof document safe is a practical way to keep physical copies secure, but digital backups are just as important. The goal is to have everything ready before the database goes live.
Watch for the Assets of Community Value changes
The English Devolution and Community Empowerment Bill also proposes widening the definition of Assets of Community Value to include properties that contribute to economic wellbeing. If your business occupies a pub, local store, or allotment, community groups could gain a ‘preferred buyer’ status — meaning they can block a sale for up to 18 months if they offer market value. That affects your ability to sell or assign the lease. If you’re in one of these categories, factor this into your exit strategy.

The next twelve months will reshape how commercial leases work in the UK. The ban on upwards-only rent reviews, the increase in minimum lease terms, and the compulsory service charge standards all point in one direction: more transparency and more protection for tenants, but also more complexity. The businesses that come out ahead will be the ones that understand these changes before they sign their next lease.
