Around one in three new UK retail leases now includes some form of turnover rent, according to recent market analysis. That means your rent is no longer a fixed annual figure — it rises and falls with your actual sales. For a business owner, that changes everything about how you plan your finances, negotiate your lease, and protect your margins. Here’s what you actually need to know.
I’ve spent years watching business owners sign commercial leases without fully understanding how turnover rent works. It comes up again and again — especially from people running shops, cafes, and gyms who think they’re getting a bargain on the base rent, only to discover later that the turnover top-up eats into their profits far more than they expected. The key is knowing what you’re agreeing to before you sign.
If you’re looking at a commercial property with a turnover rent clause, you need to understand the mechanics, the traps, and the negotiation points. I’ve pulled together the essentials from the research so you can walk into that negotiation with your eyes open.

What turnover rent actually means for your business
Turnover rent — sometimes called percentage rent — is a way of calculating your rent based on your business’s actual trading performance at the property, rather than a fixed annual amount. Most commonly, you’ll pay a base rent (set below the usual market rate) plus an additional percentage of your gross revenue earned at the premises. That percentage typically falls between 5% and 12.5% in UK retail, according to analysis from Sprintlaw.
Here’s a simple example. Say your lease sets a base rent of £40,000 per year and a turnover percentage of 7%. If your annual sales at the property reach £800,000, the turnover element would be £56,000 (7% of £800,000). You’d already be paying the £40,000 base rent through the year, so you’d owe an additional £16,000 at the end of the period. That’s the basic mechanism — but the details matter enormously.
What I’d do before signing any turnover lease is map out three scenarios: your best-case sales, your worst-case sales, and your most likely sales. Then calculate what the total rent would be in each. If the worst-case scenario still leaves you with a viable business, you’re probably in safe territory. If not, you need to negotiate harder on the base rent or the percentage.
Why turnover rent matters more than you think
Turnover rent is most common in sectors where income fluctuates — retail, hospitality, leisure, and food outlets. Shopping centres use it to align rent with footfall. A seafront restaurant in Brighton might see summer sales triple what they are in January, making a fixed rent painful in the quiet months. Turnover rent smooths that out, at least in theory.
But here’s where it gets complicated. The legal experts at So Legal point out that disputes often arise over what counts as turnover. If you run a restaurant that also does delivery through Deliveroo, does that revenue count? What about online sales from a website you run from the premises? The lease definition matters more than almost anything else.
Consider a gym that signs a turnover lease with a 10% rate and a £110,000 base rent. If membership revenue hits £1.3 million, the turnover element is £130,000 — higher than the base rent, so the total rent becomes £130,000. But if the lease includes a five-year cap of £135,000, and revenue jumps to £1.6 million after the cap expires, the rent jumps to £160,000. That’s a £30,000 increase in a single year, which could completely change your profit projections.
What I tend to notice is that landlords push for broad turnover definitions that include everything — online sales, click-and-collect, even third-party delivery revenue. If your business model includes significant off-premises sales, you need to make sure only on-premises revenue counts. Otherwise, you’re paying rent on sales that happen miles away from the property.
Where people go wrong with turnover rent
The most common mistakes I see aren’t about the concept itself — they’re about the details buried in the lease. Here are the four that cause the most trouble.
Accepting a vague definition of turnover
The lease will set out what counts as turnover, often in dense legal language. If it says “gross sales” without specifying what’s excluded, you could end up paying rent on VAT, refunds, staff discounts, and returns. The Sprintlaw analysis warns that overly broad definitions are one of the biggest traps. Make sure the lease explicitly excludes VAT, returns, refunds, and any sales that don’t happen at the premises. If you run a business with significant delivery or online sales, this is non-negotiable.

| What’s usually included | What’s often excluded (if negotiated) | What causes disputes |
|---|---|---|
| In-person sales at the premises | VAT | Online sales from a website run at the premises |
| Click-and-collect orders | Returns and refunds | Third-party delivery revenue (e.g. Deliveroo) |
| Concession sales within your space | Staff discounts | Sales made outside opening hours |
Ignoring the reporting and audit clauses
Most turnover leases require you to provide detailed monthly or quarterly turnover reports. Some give the landlord the right to audit your accounts — at your cost — if they suspect underreporting. That means you need to keep meticulous records and be prepared for the administrative burden. If you’re a small business without dedicated accounting support, this can become a significant hidden cost. The lease should spell out exactly what records you must keep, how often you report, and who pays for an audit if one is triggered.
Forgetting to negotiate a cap
Without a cap, your rent has no upper limit. If your business takes off, the landlord shares in that success — but the share can be steep. A cap protects you from paying far more than you would under a fixed lease. In the So Legal example, a five-year cap of £135,000 kept the rent manageable while the business grew. After the cap expired, the rent jumped to £160,000. If you’re planning for long-term growth, negotiate a cap that lasts beyond the initial period, or at least includes a mechanism to review it.
Overlooking what happens with concessions and sublets
If you allow another business to trade inside your premises — a coffee shop inside a bookstore, for example — does their turnover count as yours? The lease needs to be clear. Some landlords will try to include concession revenue in your turnover calculation, which means you’re paying rent on someone else’s sales. If you plan to sublet or host concessions, make sure the lease excludes that revenue from your turnover calculation.
What I’d do in this situation is get a tenant landlord lawyer to review the lease before signing. The cost of legal review is small compared to the cost of a dispute over turnover definitions down the line.

If you decide a turnover rent lease is right for your business, here’s how to approach the negotiation and ongoing management.
Define turnover precisely in the lease
This is the single most important step. Work with a solicitor to draft a clear definition of what counts as turnover. Exclude VAT, returns, refunds, staff discounts, and any sales that don’t happen at the physical premises. If you run a restaurant, make sure delivery platform revenue is excluded unless you’re genuinely preparing and serving those orders from the property. If you run a retail shop with an online store, specify that only in-person sales count. The more precise the definition, the fewer disputes you’ll have.
For a practical tool to help you track your sales data accurately, a POS system for small business can automate your reporting and make it easier to provide the turnover figures your landlord requires.
Negotiate a cap and a floor
A cap protects you from runaway rent. A floor protects the landlord from very low rent. Both are negotiable. If the landlord insists on a floor, make sure the base rent is genuinely affordable in your worst months. If you’re in a seasonal business, model what your rent would look like in the quietest quarter and make sure you can survive it. For the cap, aim for a figure that gives you room to grow without penalising your success. A five-year cap is common, but you can negotiate for a longer period or a cap that increases gradually.
Set up a reliable reporting system from day one
You’ll need to provide turnover reports at agreed intervals — monthly, quarterly, or annually. Set up your accounting system to generate these reports automatically. Keep all sales records for at least the duration of the lease plus a few years after it ends, as the lease may require it. If the landlord has audit rights, make sure you understand the process and who pays. Some leases require you to cover the cost of an audit if the landlord suspects underreporting, even if the suspicion turns out to be unfounded.
Plan for the end of any rent cap
If your lease includes a cap that expires after a set number of years, plan for what happens next. Your rent could jump significantly. Build that into your financial projections and start negotiating a renewal or extension well before the cap expires. If your business has grown during the capped period, you’ll have more leverage to negotiate a new cap or a lower percentage.
