After deciding between property renting or purchase, a commercial lease is one of the more complicated contracts that a business can decide to sign. Navigating the commercial property market involves far more than simply finding a suitable layout and agreeing on a base rental figure.
Between legal obligations and hidden structural defects that you could accidentally sign up to pay for, making sure you have a contract designed with your best interests in mind becomes a lot harder than it seems.
We’ve put together this guide for commercial tenants to support understanding of how to rent a commercial property and why seeking support from an experienced solicitor can help your business through the entire leasing journey.
Renting vs buying commercial property
It’s very common for UK business owners to rent their company’s premises, with more than half of commercial property leased rather than owned outright. While leasing offers essential flexibility and preserves vital working capital, buying a commercial property provides long-term security, complete operational control, and potential asset growth.
Considering each route is recommended, as the right path depends heavily on your company’s growth stage, cash reserves, operational flexibility, and long-term strategic goals.
Upfront costs
Renting keeps initial outlays relatively low and typically requires a deposit along with initial legal and search fees. For small businesses, this means owners can retain funds for hiring, inventory, operational dilemmas, and any other service they may like to seek.
Buying requires a much larger capital commitment with a deposit usually consisting of 20% – 40% of the purchase price, alongside Stamp Duty Land Tax (SLDT), survey costs, and commercial mortgage arrangement fees.
Room for growth
Renting offers a moderate level of flexibility when it comes to business expansion. If a business outgrows a rented space or needs to downsize, relocating, exiting at the end of the term, or exiting via a break clause are all plausible options.
Buying, on the other hand, pins your business to a specific location. This means expansion would involve selling or buying additional property, or even dealing with complicated extension permissions.
Maintenance and repairs
When renting, maintenance obligations depend mostly on the type of lease. Under a Full Repairing and Insuring (FRI) lease, tenants are the ones responsible for proper upkeep and repair of both the interior and exterior of the building.
With property purchase, you bear all of the responsibility for structural maintenance including roof repairs, environmental compliance, and building degradation.
Control and financial value
Alterations to the property, including hanging signs, usually need formal consent from the landlord when renting a commercial space. Renters also risk lease expiry and rent increases at review periods.
With property purchase, owners have free rein to do with it what they like in terms of modifications. The business also gains valuable long-term asset that can go up in value or provide certain tax benefits.
Finding a suitable property and completing initial checks
There’s lots to consider when choosing the right commercial rental space for your business needs, with the wrong selection of property being causing factor of operational delays and unexpected expenses for your business.
During initial viewings, it’s important to keep an eye out for signs of structural issues like damp, cracking plaster, outdated wiring, or sagging roof spots. Pointing these problems out early will help your solicitor draft potential protection clauses into your lease later down the line.
Furthermore, considering planning permissions and Use Classes is an important step in the UK commercial renting process, as it ensures complete compliance with local authority regulations. For example, most standard high-street businesses are categorised into Class E, meaning it’s easier to get planning permission and alter workspaces.
Pubs and other hospitality locations, however, are placed under unique planning restrictions. Always verify with the local council that your intended business activities are legally permitted at that location before committing.
Agreeing heads of terms
A Heads of Terms document is a clear summary of the core agreements negotiated between a renter and a landlord. Despite the fact that the document is not legally binding, it acts as a solid, factual base for solicitors when they’re drafting up the legally lease. The document should always include:
- Agreed annual rent
- Rent payment dates
- Lease length
- Security deposit requirements
- Targeted start dates
- Any agreed rent-free periods
The Heads of Terms should also outline whether you are free to sublet unused space, whether a break clause applies, and who carries primary responsibility for repairs.
Even though it can feel like an unimportant step, it’s important to treat your Heads of Terms document with care. This is often the key to preventing misunderstandings and frustrating back-and-forth negotiations in the future.
Surveys, searches, and due diligence
Before signing a lease, one of the best things you can do is make sure proper searches and surveys are carried out to identify any structural defects, legal restrictions or financial liabilities attached to the property.
Surveys
Before signing a rent agreement, a building survey and a specialist survey (targeting boilers and electrical systems etc.) should be carried out with a photographic and written record of the exact state of the property upon entry.
This acts as a last chance for potential tenants to uncover hidden or subtle problems with the building before signing an official lease. Having a clear documentation of how the property is upon entry means landlords will be unable to force tenants to repair pre-existing damage when moving out.
Searches
Environmental and drainage searches can confirm critical operational risks like historical pollution or direct connection to public water mains and sewers.
This is important to note as current UK environmental law can hold occupiers of properties liable for cleaning up historical pollution. Equally, confirming potential drainage connections will save waste management money later down the line.
Due diligence
Title and ownership checks may be one of the most significant checks you can make prior to a business. By checking the Land Registry, your solicitor can confirm whether or not your landlord legitimately owns the property and the legal right to lease it to you.
If a landlord has a mortgage on the property, they would need consent to grant a lease, therefore allowing the lender to evict you if the landlord defaults. Having this information will massively help you decide whether a property is right for you.
Costs beyond rent
While rent will be your main ongoing expense, running a commercial property involves additional numbers that you should factor into your business budget.
Rent deposit
A typical landlord expectation for a deposit is an amount equivalent to three to six month’s rent. This is held separately to the interest-bearing bank account and is returned at the end of the tenancy, provided the renter has met all lease obligations.
If lease obligations have not been met, a portion of the deposit is kept by the landlord to cover costs required to reinstate the building to its prior standard.
Business rates
This is a local government tax that’s based on the estimated open-market value of your property. This is set by the Valuation Office Agency (VOA) and can be checked online.
Note that if your property is your only business location and has a rateable value of £12,000 or less, you pay no business rates at all.
Service charges
In multi-let buildings (such as shopping centres or shared office blocks) tenants pay an additional ongoing fee to cover shared operational expenses. This pays for structural repairs, communal lighting, security, shared area cleaning, and lift maintenance. Always request a three-year record of past charges and request your solicitor to negotiate a service charge cap in case of unexpected price spikes.
Additionally, if your landlord takes up the option to tax the building they’re leasing (as this is not automatic) 20% VAT (Value Added Tax) will be added to a tenant’s monthly rent. While this can be reclaimed, the impact on your business cash flow must be accounted for.
Insurance and utilities
Landlords will normally arrange an overarching building insurance policy, known as insurance rent, and bill the cost back to the tenant. Aside from this, tenants still need their own contents and public liability insurance.
Utilities like gas, water, electricity, and broadband are almost always paid by the tenant.
Common mistakes made by commercial tenants
Comprehending a commercial lease, especially when facing one for the first time, can be difficult at the best of times. Even small oversights or quickly skimming over sections that don’t seem important can quickly lead to financial and legal issues.
Here are a few common mistakes that commercial tenants make and how to avoid them.
Skipping legal reviews
Signing a legal review or agreeing to legally binding terms within a draft lease can lead to harsh terms against the tenant, un-capped liabilities, or even unexpected legal obligations that could have been negotiated away.
To avoid this, tenants should involve an experienced solicitor in the entire commercial lease process. This removes the risk of any nasty surprises months later when it’s too late to change anything.
Ignoring full repair obligations
Accepting a Full Repairing and Insuring (FRI) lease (a lease where the tenant carries the complete financial and practical burden of making repairs on the property) risks the chance of being made to pay for repairs, despite the problem being there before your tenancy started.
By attaching a Schedule of Condition, you can limit liability and avoid forking out funds for repairs that weren’t your fault. It’s important to remember that there will always be certain tenant responsibilities enforced by law that tenants cannot negotiate away.

Missing break clause deadlines
Break clauses offer a reasonable exit route from a lease when tenants need it most, however, they come with strict legalities and failing to strictly meet every condition of the clause can completely invalidate the whole clause.
Having a solicitor negotiate this term for you is the recommended route, as it’s professional and safe way to make sure your break clause is exactly how it should be, with no hidden or complicated terms that are easy to miss.
How a solicitor can negotiate terms to protect the tenant
A commercial landlord’s lease is generally drafted to favour their personal interests. A commercial property solicitor is able to protect tenants from agreeing to terms that trap them in unfair obligations or limit their flexibility operationally. Solicitors can:
- Limit repair liabilities with a Schedule of Condition, ensuring you can return property in the exact condition you received it.
- Protect renewal rights by advising tenants whether you should sit inside or outside of the Landlord and Tenant Act 1954. Keeping it inside means ensuring your business has a legal right to renew the lease at market rates.
- Review local authority, title, and environmental searches in order to uncover any lacking proper planning permissions or title covenants that could halt a tenant’s daily operations.
- Ensure lease flexibility like break clauses and broad assignment meaning you can exit a lease early with no hassle or even transfer it to another business if you’re looking to scale back.
