Commercial Property Rent Increases: What To Know Before Renewing A Lease

If you’re coming up to a lease renewal, a commercial property rent increase is often the first (and biggest) thing on your mind.

That makes sense. Rent is usually one of your highest fixed costs, and even a “modest” uplift can reshape your monthly cashflow, your hiring plans, and how confidently you can invest in the business.

The good news is you’re not powerless here. Many rent increases are negotiable, and the legal position depends heavily on your current lease terms and whether you have rights under the Landlord and Tenant Act 1954 (often called “security of tenure”).

Below, we’ll break down how commercial rent increases typically work in the UK, what to look for before you renew, and how to negotiate a deal that supports your business long-term.

Why Do Commercial Rent Increases Happen (And When Are They Usually Raised)?

A commercial property rent increase can pop up at a few different moments in the life of a lease. The tricky part is that each scenario follows different rules.

1) Rent Review During The Lease Term

Many commercial leases include a rent review clause (often every 3 or 5 years). If yours has one, the rent can change mid-lease even if you’re not renewing.

Typical rent review methods include:

• Open market rent (the rent is adjusted to reflect current market value).
• Index-linked increases (often linked to RPI or CPI).
• Fixed uplifts (e.g. a 3% increase every year).
• Turnover rent (common in retail/hospitality; rent is tied to revenue, sometimes with a base rent too).

Some leases include “upward-only” rent reviews, meaning the rent can go up but not down, even if market rents have fallen. This is a big deal for budgeting and negotiation.

If you want a deeper sense check on timing and patterns, this can help: commercial lease increases.

2) Rent Increase On Renewal (New Lease Terms)

At renewal time, the landlord may propose a higher rent as part of the new lease deal (even if there wasn’t a rent review mid-term). This is where many businesses feel the pressure, because the renewal often coincides with a deadline to decide whether you’ll stay, move, or renegotiate.

3) Rent Increase Through Side Costs (Not Just “Rent”)

Sometimes the headline rent looks stable, but your overall occupancy cost increases due to:

• service charge changes
• building insurance recharges
• business rates changes (not controlled by the landlord, but still part of your real costs)
• repair obligations and dilapidations exposure

So when you’re assessing a commercial property rent increase, it’s worth checking whether the increase is really about rent, or about the total cost of occupation.

What Should You Check In Your Current Lease Before You Even Talk Numbers?

Before you negotiate, you’ll want to understand what you’ve already agreed to in the existing lease. That’s because your current lease will usually influence:

• your rights to renew (or not)
• how “strong” your negotiating position is
• what costs you might face if you leave
• what terms the landlord is likely to push for again

Rent Review Clause (And Any “Upward-Only” Wording)

Check exactly how rent is reviewed and how it’s calculated. The drafting matters. For example, open market rent provisions usually include assumptions and disregards (such as ignoring tenant improvements), and those details can change the outcome significantly.

Break Clauses

If you have a break clause coming up (or you can negotiate one), that can be a powerful lever. Landlords often prefer certainty, so a tenant who can genuinely walk away may be able to negotiate a softer rent increase or better incentives.

Repairing Obligations And Dilapidations Risk

If your lease is “full repairing and insuring” (FRI), you may be on the hook for substantial repair obligations. This matters at renewal because:

• you may want to negotiate a cap or clarity around repairs in the new lease
• you might choose to move rather than renew if the property will be expensive to hand back in good condition

Alienation Clauses (Assignment/Subletting)

Even if rent increases, a lease can still be manageable if you have flexibility to assign or sublet later. If your lease is restrictive here, that’s a commercial risk worth addressing at renewal.

If you’re in retail, the fit-out, user clause and trading restrictions can be just as important as rent. This is where a Commercial Lease Review (Retail) can be particularly helpful, because retail leases often hide costs and constraints in the detail.

Security Deposit And Guarantees

Renewal is also when landlords may ask for a bigger rent deposit or different security (like a guarantor). If you’re negotiating a commercial property rent increase, you’ll want to factor security into the deal because it affects your cashflow.

It’s worth knowing what’s “normal” and what’s negotiable in your sector: rent deposits.

How Does The Law Work On Lease Renewal And Rent (Landlord And Tenant Act 1954)?

This is one of the biggest “hidden” factors in commercial lease renewals: do you have security of tenure?

In plain English, security of tenure usually means you may have a legal right to apply for a new lease when the contractual term ends, and the landlord can only refuse renewal on certain statutory grounds (for example, redevelopment plans or persistent tenant breach). The rent and other terms are then negotiated, and if they can’t be agreed, they can be determined through the statutory process.

Do You Have “Security Of Tenure”?

Many business leases in England and Wales are protected by the Landlord and Tenant Act 1954, but some are “contracted out” of the Act. If your lease was contracted out, you generally don’t have the same automatic statutory right to renew, and the renewal terms (including rent) will be driven more by commercial bargaining power.

This matters because where the Act applies, rent on renewal is generally assessed on a market basis using the statutory assumptions and disregards if you can’t agree. Where the Act does not apply, the landlord is not required to grant a renewal at all, and can set whatever terms it is willing to offer.

What Happens If You Can’t Agree The Rent?

Where the 1954 Act applies, the renewal process is often started by:

• a Section 25 notice from the landlord, or
• a Section 26 request from the tenant.

If you can’t agree the rent and key terms, the matter can ultimately be determined by the court (though many businesses settle well before that point).

Rent on renewal is typically based on market rent (with various assumptions/disregards set out in the Act). This is a technical area, but the practical takeaway is:

• evidence matters (comparables, condition, incentives, fit-out contributions, and local demand)
• timing matters (missed deadlines can hurt your position)
• the rent figure is often part of a wider package (lease length, break rights, rent-free periods, and repair obligations)

Interim Rent Can Apply

Another point businesses sometimes miss: even while renewal terms are being negotiated, an interim rent can be payable in some cases. So if your lease is continuing after expiry during the renewal process, don’t assume the rent will stay exactly the same until the new lease is signed.

Because renewal strategy depends on your lease wording and your business goals, getting a Commercial Lease Review early can save you from negotiating blind.

How Can You Negotiate A Commercial Property Rent Increase Without Getting Cornered?

Negotiating a commercial property rent increase is rarely just about “pushing the rent down”. The strongest outcomes usually come from treating the lease as a package of risks and trade-offs.

Here are practical ways to approach the negotiation.

1) Get Clear On Your “Walk Away” Position

Before you counteroffer, work out:

• What rent can your business genuinely afford?
• What would relocation cost (fit-out, downtime, moving costs, marketing the new location)?
• How quickly could you realistically move?
• Is there a nearby alternative property that meets your needs?

If you can’t credibly move, you can still negotiate, but you’ll want to focus more on other terms (rent-free period, break clause, cap on service charge, repair limits).

2) Ask What The Increase Is Based On

Landlords often justify increases by pointing to “market rent”. That may be true, but “market” depends on evidence and assumptions.

You can ask for:

• comparable properties they’re relying on (size, condition, incentives)
• details of any rent-free periods given to new tenants (this affects the real market deal)
• whether the proposed rent assumes a certain lease length or repair obligation

3) Negotiate The Shape Of The Deal (Not Just The Number)

If the landlord won’t move much on rent, you can sometimes negotiate:

• Rent-free period at the start of the renewed term
• Stepped rent (lower in year 1, gradually increasing)
• Shorter term with a break clause (flexibility if trading changes)
• Tenant fit-out contribution (especially if the premises need works)
• Cap on service charge or clearer service charge rules
• Limitations on repairing obligations (for example, schedule of condition)

For many small businesses, the “best” deal is the one that keeps occupancy costs predictable and reduces nasty surprises later.

4) Watch Out For Heads Of Terms That Quietly Lock You In

Heads of terms are often described as “non-binding”, but they can still create momentum and shape what’s treated as agreed. The key is to make sure the commercial points you care about are properly reflected before the lawyers start drafting the renewal documents.

5) Use Your Business Value As Leverage

Landlords often prefer a stable tenant who pays on time and looks after the premises. If you’ve been reliable, you can lean into that value:

• offer a longer commitment in return for a smaller increase
• offer stronger reporting (where turnover rent applies) in return for a better structure
• agree to certain works if the landlord provides a rent-free period

It’s a negotiation - your aim is a lease that supports your business, not just a rent figure that sounds “reasonable”.

What Else Increases The Cost Of Your Premises (Even If The Rent Looks OK)?

A commercial property rent increase can be obvious (a higher monthly rent), but many businesses get caught by increases elsewhere in the lease.

Service Charge

If you’re in a building with shared areas (common in offices and retail), service charge can fluctuate significantly. A renewal is a good time to negotiate:

• a cap on service charge (or at least limits on certain spend categories)
• clearer budgeting and reconciliation obligations
• exclusions (e.g. major capital works, landlord improvement projects)

Insurance Rent

Many leases require you to reimburse the landlord’s building insurance premium. Premiums can rise year to year, and some leases allow the landlord to recover additional insurance-related costs too.

Repair And Compliance Obligations

Renewal documents sometimes expand what you’re responsible for, even if the rent increase seems modest. Examples include:

• tighter obligations to redecorate at the end of the term
• expanded obligations around plant and equipment maintenance
• changes to statutory compliance obligations (fire safety, accessibility, signage rules, etc.)

Rent Deposit Increases Or New Guarantees

Landlords sometimes use renewal to “reset” risk and ask for:

• a larger rent deposit
• a personal guarantee
• a guarantor company (if you’re part of a group)

That’s why it’s important to evaluate the renewal as a full package: rent + security + repairing obligations + service charge + flexibility.

Is A Licence To Occupy An Option Instead Of Renewing?

If you’re uncertain about committing to a longer lease (for example, you’re trialling a new location or your business model is changing), you might consider a shorter, more flexible arrangement.

In some cases, a licence to occupy can be an option, although it offers different rights and protections compared to a lease. Whether it’s suitable depends on your bargaining position and what you need operationally.

Key Takeaways

• A commercial property rent increase can happen through rent review clauses during the term, or through new terms agreed at renewal - and the legal rules can differ significantly.
• Before negotiating, check your current lease carefully for rent review mechanics (including any upward-only wording), break clauses, repairing obligations, and rules on assignment/subletting.
• Your renewal rights may depend on whether your lease is protected by the Landlord and Tenant Act 1954 or contracted out, which can materially affect your negotiating leverage and the renewal process.
• When negotiating, focus on the full deal: rent, rent-free periods, stepped rent, lease length, break rights, service charge caps, repair limitations, and deposit/guarantee requirements.
• Don’t assess rent in isolation - service charge, insurance recharges, compliance obligations and dilapidations risk can increase your real cost of occupation even if the headline rent looks manageable.
• Getting advice early (before heads of terms are locked in) can help you avoid signing up to hidden risks that are hard to unwind later.
