When buying a business with an existing lease, you are not only buying the trade, stock, goodwill, or equipment. You are also taking on the legal rights and duties linked to the premises. If the lease has poor terms, high rent, repair problems, or landlord restrictions, it can affect the value of the business and your ability to run it properly.
For many business owners, the lease is one of the most important parts of the deal. This is especially true if the business depends on its location, such as a shop, restaurant, salon, office, takeaway, or warehouse.

Why the Lease Matters When Buying a Business
A business may look profitable on paper, but the lease can change the whole picture.
Before you agree to buy, you need to know:
- How long the lease has left
- How much rent is payable
- What extra charges apply
- Whether the lease can be transferred to you
- What the landlord must approve
- What repairs you may become responsible for
- Whether you can use the premises for your planned business
- Whether the lease allows you to sell the business later
Most commercial leases restrict assignment, which means the lease cannot usually be transferred to a buyer without the landlord’s written consent.
Check Whether the Lease Can Be Assigned
When buying a business with an existing lease, one of the first checks is whether the current tenant can transfer the lease to you.
This process is called assignment.
An assignment means the seller transfers their lease to the buyer. Once completed, the buyer usually becomes responsible for the lease from that point onward.
You should check:
- Whether assignment is allowed
- Whether landlord consent is needed
- What information the landlord can request
- Whether the landlord can impose conditions
- Whether the seller must enter into an Authorised Guarantee Agreement
- Whether you need to provide a rent deposit or personal guarantee
The landlord may ask for financial evidence from the buyer before giving consent. They may also set reasonable conditions before approving the lease transfer.
Check the Remaining Lease Term
The length of the lease matters.
A lease with only a short term left may reduce the value of the business. You may not have enough time to recover your investment, especially if you plan to spend money on refurbishment, equipment, staff, or marketing.
You should ask:
- How many years are left on the lease?
- Can the lease be renewed?
- Is there security of tenure under the Landlord and Tenant Act 1954?
- Has the lease been contracted out of renewal rights?
- Is the landlord likely to agree to a new lease?
- Could the landlord ask for a higher rent on renewal?
If the lease is too short, you may want to negotiate a new lease before completing the business purchase.
Check the Rent and Rent Review Terms
Do not only check the current rent. You also need to check how the rent may change.
Look for:
- Current rent
- Rent review dates
- How rent reviews are calculated
- Whether rent can only go up
- Market rent review clauses
- Fixed rent increases
- Turnover rent clauses
- VAT on rent
A rent review can make a business less profitable if the rent increases after you buy it.
You should understand the lease terms before you agree to the purchase price.
Check Service Charges and Other Costs
The rent is not always the full cost of the premises.
The lease may also require payment of:
- Service charges
- Insurance rent
- Maintenance costs
- Repairs
- Utilities
- Business rates
- Management fees
- Legal fees linked to the assignment
Service charges can be a problem if they are unclear or open-ended. You should ask for recent service charge accounts and details of any planned works.
Check Repair Responsibilities
Repair clauses can create serious risk for buyers.
Some commercial leases make the tenant responsible for keeping the premises in repair. This can include putting the property into a better condition than it was in when the lease started, depending on the wording.
Before buying the business, check:
- Who repairs the structure?
- Who repairs the roof?
- Who repairs the shopfront?
- Who repairs internal areas?
- Are there existing defects?
- Is there a schedule of conditions?
- Has the landlord raised any repair issues?
- Could there be dilapidations at the end of the lease?
If you take over the lease, you may take on existing repair responsibilities.
This can lead to unexpected costs.
Check the Permitted Use
The lease should state what the premises can be used for.
This is called the permitted use.
You must check whether the permitted use matches your plans. For example, a lease may allow use as a retail shop but not as a takeaway, restaurant, clinic, or office.
You should check:
- The permitted use in the lease
- Planning permission
- Licensing requirements
- Any landlord restrictions
- Any limits on opening hours
- Any restrictions on noise, cooking, signage, or alterations
If your planned use is not allowed, you may need landlord consent, planning advice, or a licence before you trade.
Check Whether Alterations Are Allowed
If you plan to change the premises, you must check the alterations clause.
You may need landlord consent before making changes such as:
- Installing signage
- Changing the layout
- Adding partitions
- Installing extraction systems
- Changing flooring
- Adding equipment
- Refitting a shop, salon, or restaurant
Some leases ban structural alterations. Others allow changes only with written consent.
Do not assume you can change the premises after completion.
Check Personal Guarantees and Rent Deposits
The landlord may ask you for extra security before consenting to the assignment.
This may include:
- A personal guarantee
- A rent deposit
- A guarantor
- Bank references
- Business accounts
- Proof of funds
A personal guarantee can put your personal finances at risk if the business cannot meet the lease obligations.
You should understand the risk before signing.
Check Whether the Seller Remains Liable
In some cases, the seller may remain liable after the lease is assigned.
This often happens through an Authorised Guarantee Agreement, known as an AGA.
An AGA means the outgoing tenant guarantees that the incoming tenant will comply with the lease. If the buyer fails to pay rent or breaches the lease, the landlord may have rights against the seller.
This matters for the seller, but it can also affect the buyer because it may become part of the negotiation.
Check Existing Lease Breaches
Before buying a business with an existing lease, you should find out whether the seller has breached the lease.
Examples include:
- Rent arrears
- Unauthorised alterations
- Failure to repair
- Unauthorised use
- Missing insurance payments
- Unapproved signage
- Subletting without consent
- Breach of trading rules
A landlord may refuse or delay consent if there are existing lease breaches. Landlords may also ask for breaches to be fixed before the assignment completes.
Check Landlord Consent Early
Landlord consent can delay a business purchase.
The seller should usually apply for consent to assign the lease. The landlord may then ask for information about you as the buyer.
This may include:
- Business plan
- Financial records
- References
- Identity documents
- Experience in the sector
- Details of your intended use
- Details of your company structure
The Landlord and Tenant Act 1988 can place duties on landlords when consent is required, including a duty not to unreasonably withhold consent where the lease contains a qualified covenant.
Even so, the process can still take time.
Check What Documents Are Needed
A business sale involving an existing lease may need several legal documents.
These may include:
- Business sale agreement
- Lease review report
- Licence to assign
- Deed of assignment
- Authorised Guarantee Agreement
- Rent deposit deed
- Stock transfer documents
- Employee transfer documents
- Completion statement
- Landlord consent documents
LegalVision notes that common documents in a lease transfer include a Licence to Assign, Deed of Assignment, and possibly an Authorised Guarantee Agreement.
Check Employees, Stock and Equipment
The lease is only one part of the purchase.
You should also check what else is included in the deal.
This may include:
- Staff
- Stock
- Fixtures and fittings
- Equipment
- Customer lists
- Supplier contracts
- Website and domain names
- Social media accounts
- Licences
- Vehicles
- Intellectual property
If staff transfer with the business, employment law issues may apply.
You should get legal advice before agreeing to the deal structure.
Check Whether You Are Buying Assets or Shares
There is a difference between buying the assets of a business and buying the company that owns the business.
An asset purchase usually means you buy selected business assets, such as stock, equipment, goodwill, and the lease.
A share purchase means you buy the company itself.
The lease position can be different depending on the deal structure. In a share sale, the tenant under the lease may remain the same company, but the lease may still contain change of control restrictions.
You should check this before agreeing terms.
Common Mistakes Buyers Make
When buying a business with an existing lease, buyers often make these mistakes:
- They agree the price before checking the lease
- They assume the landlord will approve the transfer
- They do not check repair duties
- They ignore rent review clauses
- They miss service charge risks
- They do not check permitted use
- They sign a personal guarantee without advice
- They complete without checking lease breaches
- They fail to plan for delays
- They do not check whether the lease can be renewed
These mistakes can lead to extra costs, delay, or a failed purchase.
What Your Solicitor Should Check
Your solicitor should review the lease and related documents before you commit.
They should check:
- Lease term
- Rent and rent review clauses
- Service charge terms
- Repair obligations
- Assignment rules
- Landlord consent requirements
- Personal guarantee risks
- Permitted use
- Alteration rules
- Insurance terms
- Break clauses
- Renewal rights
- Existing breaches
- Completion documents

Final Thoughts
Buying a business with an existing lease can be a good opportunity, but the lease must be checked before you complete.
The lease affects your rent, legal duties, repair costs, trading rights, future sale options, and long-term business risk.
Before you buy, check the lease, ask the right questions, and get legal advice. A bad lease can turn a good business into a costly problem.
