If you’re a business owner looking to lease commercial space in a UK suburb, the landscape is shifting faster than it has in years. Recent proposals in the English Devolution and Community Empowerment Bill could ban upwards-only rent reviews in new leases, while a new business rates revaluation takes effect in April 2026. These aren’t distant policy debates — they directly affect what you’ll pay and how much negotiating power you have. I’ve been following commercial property law for a while now, and the sheer volume of change coming in the next 18 months is something I haven’t seen in a long time. Here’s what you actually need to know.
If you’re looking for a practical starting point, I’d recommend getting a Tenant Landlord Lawyer to review your lease terms before you sign anything — especially with the proposed ban on upwards-only rent reviews potentially changing the game. For more on the basics, you might also want to read our guide on understanding private sector leases for your business needs.
What the proposed ban on upwards-only rent reviews means for you
An upwards-only rent review clause means your rent can only go up or stay the same — it can never decrease, even if the market drops. That’s been standard in UK commercial leases for decades, and it strongly favours landlords. The proposed ban in the English Devolution and Community Empowerment Bill would change that for new leases and renewals. If it passes, your rent could fall with the market, which is a significant shift in negotiating power.
What I’d do right now is pay close attention to the Bill’s progress through Parliament — it’s at committee stage in the House of Lords as of early 2026. If you’re negotiating a new lease, it’s worth asking whether the landlord would agree to a rent review clause that allows downward movement, even if the law hasn’t changed yet. Some landlords may be willing to negotiate now to avoid being forced into it later.

Why the 2026 business rates revaluation matters for suburban tenants
Business rates are a tax on the property you occupy, and they’re based on the property’s rateable value — essentially the annual rent the property could achieve on the open market. On 1 April 2026, a new revaluation takes effect in England, updating those values based on rental values as of 1 April 2024. That’s a big deal because it resets the baseline for what you’ll pay.
Here’s the practical impact: if your suburban retail or hospitality property has a rateable value below £500,000, you’ll benefit from a lower multiplier under the new structure. But if your property is valued at £500,000 or more, you’ll fall under a higher “high-value” multiplier. The government confirmed this in the November 2025 Budget, with the lower rates for qualifying properties funded by higher rates on larger premises.
Let’s say you run a small restaurant in a Surrey suburb with a rateable value of £150,000. Under the new structure, you’d pay a lower multiplier than a large department store in the same area. That’s a real saving. But if you’re leasing a larger suburban office with a rateable value of £600,000, you’d face the higher multiplier. Transitional relief will phase in larger increases, so you won’t feel the full impact immediately, but it’s worth factoring into your budget.
What I’d do is check your property’s rateable value now — you can find it on the Valuation Office Agency website. If it’s close to the £500,000 threshold, a small change in the revaluation could push you into a different bracket. Also, remember you can challenge the valuation through the Check, Challenge, Appeal process if you think it’s wrong.

Where people go wrong when leasing suburban commercial property
Ignoring the EPC requirements until it’s too late
Energy Performance Certificates are changing significantly. The government’s consultation on reforming the Energy Performance of Buildings framework closed in February 2025, and the changes are expected in the second half of 2026. Instead of a single score, EPCs will show multiple metrics: fabric efficiency, heating efficiency, smart-technology readiness, energy use, and carbon emissions. Validity periods may shorten from the current ten years, and landlords will need to maintain a valid EPC throughout the tenancy — not just at the start or renewal.
The mistake I see most often is tenants not checking the EPC rating before signing a lease. If the property has a low rating, you could face higher energy costs and, under future rules, potentially be unable to let the property at all. The government is also considering including listed and heritage buildings in EPC and Minimum Energy Efficiency Standards requirements, which would affect many suburban properties.
What I’d do is ask for the current EPC before you even view the property. If it’s below a C rating, factor in the cost of upgrades. A Wi-Fi water leak detector is a small investment that can help you monitor for issues that could affect energy performance, but the bigger picture is understanding what improvements the landlord is willing to make.
Overlooking the service charge code update
The updated RICS Professional Standard on service charges in commercial property took effect on 31 December 2025. It’s compulsory for all RICS-accredited professionals and sets industry benchmarks for how service charges should be calculated, presented, and disputed. While it doesn’t override your lease terms, it’s a vital reference point if you think you’re being overcharged.
The mistake here is assuming the service charge is fixed and non-negotiable. It’s not. The new code gives you more leverage to challenge unreasonable charges, especially if the landlord isn’t following the benchmarks. For a deeper dive, see our article on the recent court ruling on service charges for UK commercial rentals.
Not understanding the security of tenure changes
Security of tenure under Part 2 of the Landlord and Tenant Act 1954 gives you the right to renew your lease at the end of the term. The Law Commission is consulting on increasing the minimum term for protected tenancies from six months to two years. That means if you’re signing a short-term lease, you might lose the right to renew if the law changes.
The mistake is signing a lease shorter than two years without understanding the implications. If the minimum term increases, you could find yourself in a contractual tenancy without security of tenure. What I’d do is ask your solicitor to explain whether the lease is contracted out of the Act and what that means for your renewal rights. A Tenant Landlord Lawyer can help you navigate this.

Review your lease terms before the rent review ban takes effect
If the ban on upwards-only rent reviews becomes law, it will apply to new leases and renewals — not existing ones. That means if you’re currently in a lease with an upwards-only clause, it will remain in place until you renew or sign a new lease. The Bill is at committee stage in the House of Lords, and while it could become law in late 2026 or 2027, it’s not certain when it will come into force.
What I’d do is review your lease now. If you’re approaching a renewal, consider whether you can negotiate a rent review clause that allows downward movement. Even if the landlord resists, having the conversation puts you ahead of the curve. For more on this, read our guide on navigating landlord service charges in the UK.
Check your property’s EPC and plan for upgrades
The new EPC regime will require landlords to maintain a valid certificate throughout the tenancy, not just at the start. That means if your lease runs for five years, the landlord will need to ensure the EPC doesn’t expire mid-term. With validity periods potentially shortening, this could become a recurring cost.
If you’re a tenant, you can use this as a negotiating point. Ask the landlord to confirm the EPC rating and whether any upgrades are planned. If the property has a low rating, you might negotiate a rent reduction or a contribution to energy efficiency improvements. A carbon monoxide alarm is a small step toward better energy management, but the real work is understanding the building’s fabric efficiency and heating system.
Understand the new business rates structure before signing
The April 2026 revaluation will update rateable values based on rental values from April 2024. If your property’s rental value has changed significantly since then — for example, if suburban rents have risen or fallen — your rates could change accordingly. The new multiplier structure means lower rates for qualifying retail, hospitality, and leisure properties under £500,000, but higher rates for larger premises.
What I’d do is ask the landlord or agent for the current rateable value and an estimate of what it might be after the revaluation. You can also check the Valuation Office Agency’s website for the current figure. If you think the valuation is wrong, you can challenge it through the Check, Challenge, Appeal process.

- 1Check your property’s current rateable valueVisit the Valuation Office Agency website and search by postcode. Note the figure and compare it to the £500,000 threshold.
- 2Review your lease’s rent review clauseLook for the words “upwards only” or “upward only” in the rent review section. If it’s there, consider negotiating a change at renewal.
- 3Ask for the current EPCRequest the certificate from the landlord. Check the rating and the expiry date. If it’s below C, discuss upgrades before signing.
- 4Consult a solicitor on security of tenureAsk whether the lease is contracted out of the Landlord and Tenant Act 1954 and what that means for your renewal rights.
Plan for the Business Property Relief changes if you own the property
From 6 April 2026, Business Property Relief and Agricultural Property Relief will be combined into a single £1 million allowance at 100%. Any qualifying value above that threshold will receive only 50% relief, creating an effective 20% inheritance tax charge on the excess. Shares in unlisted companies, including AIM-listed shares, will also receive only 50% relief.
If you own the commercial property you lease, this change could affect your estate planning. The £1 million allowance is generous, but if your property is worth more than that, the excess will be taxed at 20% on inheritance. What I’d do is speak to a financial advisor about restructuring your ownership or considering life insurance to cover the potential tax liability.
