Transferring a commercial lease, often called assigning a lease, can be a practical way to deal with premises that no longer fit your business. Perhaps you’re relocating, downsizing, selling, restructuring, or moving into larger space before the lease ends.
Assignment can reduce your exposure, but it doesn’t always give you a clean break. The lease terms, landlord consent requirements, registration position, repair obligations, rent deposits, and any authorised guarantee agreement can all affect timing, cost, and future liability.
This guide is for business owners, directors, finance leads, and managers looking to pass their lease to another business. You’ll understand when assignment may be commercially sensible, what the main stages involve, and where issues such as landlord consent, timing, costs, and ongoing liabilities can affect your plans.

When does assigning a lease make commercial sense?
A tenant will generally look to assign its lease when it no longer needs the property but there is still time left before the lease ends. For example, your business may have taken a five-year lease, but after two years you need to move. Unless the lease includes a break clause, the landlord agrees a surrender, or another structure such as sub-letting is available, you may have to continue paying rent and complying with the lease for the remaining three years.
By assigning the lease, you can transfer the lease to a new tenant and reduce your future exposure. It’s not always a complete release from all risk, but it can be a sensible way to stop an empty or unsuitable property becoming a drag on cash flow.
If there is less than a year remaining on the lease, it may be harder to find someone who wants to take the property for such a short period. In that situation, you may decide that staying put, negotiating with the landlord, or exploring another option makes more commercial sense.
Common reasons for assigning a lease include:
- You’ve agreed to sell your business and the transaction structure requires the lease to be assigned to the buyer.
- Your business isn’t trading as well as expected and you need smaller or less expensive premises.
- The property is no longer in the right location for your team, clients, suppliers, or customers.
- Your business has grown faster than expected and you need larger premises.
- You’re restructuring your group or changing how different parts of the business use property.
What should you check before marketing the lease?
Before you start speaking to potential assignees, review the lease so you understand the assignment restrictions, permitted use, repair obligations, service charge position, break rights, rent review provisions, landlord consent requirements, and whether the lease is registered.
You should also check whether there is a valid Energy Performance Certificate and whether any minimum energy efficiency issues could affect the transaction. This is easy to miss. But if a prospective assignee spots an EPC issue, a heavy repairing obligation, or an awkward break clause late in the process, it can slow everything down or give them a reason to renegotiate.
It’s also worth thinking about the property from the assignee’s point of view. Is the rent still competitive? Are there upcoming rent reviews? Are there dilapidations concerns? Is the permitted use broad enough for the market you’re targeting? A lease that looks manageable to you may look risky to an incoming tenant if the cost profile is unclear.
Key stages in assigning a commercial lease
Assigning a lease means transferring your lease to another person or business so that they become the new tenant. Once the assignment has taken place, the lease continues and the assignee takes over the tenant obligations from that point, subject to the lease terms and any ongoing liabilities you have agreed or remain responsible for.
The first stage is to find someone who wants to take over the lease. They are known as the assignee. Aside from being comfortable with the rent, the assignee will want to review the lease to check that it does not contain terms that are too restrictive, expensive, or unsuitable for their plans.
This process will feel similar to the checks your solicitor carried out when you first negotiated the lease. The difference is that the assignee is taking over the existing lease. They usually have little or no ability to change the lease terms, so they need to be comfortable with the lease as it stands.
If the lease contains terms that are unusual, expensive, or likely to affect the assignee’s intended use, you may have problems assigning it. It is worth knowing this before you start marketing the lease. For example, there’s little value in marketing a warehouse to manufacturing businesses if the lease prohibits industrial use.
Most assignees will also want to carry out due diligence in the same way they would if they were taking a new commercial lease. This may involve property searches, enquiries with the local authority, utility checks, environmental questions, and a review of the physical condition of the property. This takes time, so it is rarely realistic to expect a lease assignment to happen instantly.
Once an assignee is found and the parties are ready to proceed, the assignment is usually documented by a deed of assignment. If landlord consent is needed, there will usually also be a licence to assign. After completion, the parties may need to serve any notices required by the lease, deal with Stamp Duty Land Tax filings where relevant, and register the assignment at HM Land Registry where the registration rules require it.
You can only assign your lease freely if the lease allows you to do so. Most commercial leases contain restrictions on assignment, and in many cases you will need the landlord’s consent before the assignment can go ahead. This is where many of the practical issues arise, and we have written an article covering what you can do if a landlord unreasonably withholds consent in this scenario.
Is a licence to assign needed to transfer a commercial lease?
A licence to assign is the document that records the landlord’s consent to the assignment. It usually sits alongside the deed of assignment and confirms the conditions on which the landlord is prepared to let the lease transfer to the assignee.
Most landlords are mainly concerned with protecting the income and value of their property. They want to know that the incoming tenant can pay the rent, comply with the lease, and look after the property. They may also be concerned about the proposed use of the property, the assignee’s financial strength, and whether any guarantor or rent deposit is needed.
A landlord will usually want comfort that the assignee can:
- Pay the rent in full and on time.
- Keep the property in the condition required by the lease.
- Use the property lawfully and in a way that fits the lease and wider property.
- Avoid causing problems for the landlord’s other tenants, neighbouring occupiers, or future letting strategy.
That is why most leases give the landlord some control over assignment. The licence to assign is the formal record of that control being exercised.
Do you need the landlord’s consent to assign a commercial lease?
Whether you need the landlord’s consent depends on the terms of the lease. Most commercial leases contain some restriction on assignment. Some prohibit assignment entirely. Some allow assignment only with the landlord’s consent. Some allow assignment subject to specific conditions.
If the lease does not restrict assignment at all, you may not need a licence to assign. That is unusual in modern commercial leases.
Although assignment clauses can look intimidating, many leases say the landlord’s consent is needed before the lease can be assigned. Where the statutory consent regime applies, the landlord must usually not unreasonably withhold consent. Once a proper written application is made, the landlord must also deal with it within a reasonable time, unless it is reasonable to refuse consent.
You should ask for the landlord’s consent as early as possible and provide a proper pack of information with your request. That might include details of the assignee, its proposed use of the property, financial information, references, company accounts, details of any proposed guarantor, and confirmation of how any arrears, repairs, or other lease breaches will be dealt with.
The lease may also set out conditions that must be satisfied before consent is given. Common examples include payment of the landlord’s legal costs, completion of an authorised guarantee agreement, provision of a rent deposit, or confirmation that there are no rent arrears.
If the proposed assignee is not financially strong enough to satisfy the landlord, consent may still be possible if extra security is offered, such as a guarantor or rent deposit. What the landlord can insist on will depend on the lease wording and the circumstances.
You should also be aware that a landlord may ask you, as the outgoing tenant, to enter into an authorised guarantee agreement. This means you guarantee the assignee’s performance of the tenant obligations under the lease, usually only while that assignee remains the tenant. So assignment does not always mean you can walk away with no future risk.
In practical terms, you will need to show that the assignee is likely to pay the rent and comply with the lease. If the landlord has reasonable concerns about that, it may be able to refuse consent or require suitable security, depending on the lease and the circumstances.
If your lease expressly prohibits assignment and does not give the landlord power to consent, the starting point is that you cannot assign it. The landlord may still decide to agree, but it would not usually be under the same statutory duty to act reasonably or quickly. This is one of those moments where the exact wording of the lease really matters.
Actual assignments, virtual assignments, and share sales
Most commercial lease transfers happen by actual assignment. This is where the tenant assigns its interest in the lease to the assignee, the assignee becomes the tenant, and the lease continues.
In some cases, a tenant may explore a virtual assignment. This is where the tenant remains liable under the lease but enters into an arrangement with a third party to transfer the economic benefit and burden of the lease without formally assigning it. These structures are sometimes considered where the lease contains very restrictive assignment clauses.
They need careful advice. A virtual assignment can still breach lease restrictions on assignment, underletting, sharing occupation, parting with possession, or holding the lease on trust. It may also leave you exposed if the third party fails to perform. In plain English: it may look like a workaround, but it can create a new set of problems if it is not handled properly.
If the tenant is a company and the shares in that company are sold, the lease itself does not transfer. The tenant remains the same company. However, some leases contain change of control provisions that restrict changes in shareholding or group ownership. This is especially common where the landlord has relied on the covenant strength of the original tenant or its group.
Registering a commercial lease assignment
If the lease is already registered, most assignments must be completed by registration at HM Land Registry. If the lease is unregistered but has more than seven years left to run at the date of assignment, the assignment will usually trigger compulsory first registration.
The assignee usually deals with registration because they are the party who needs the leasehold title put into their name. Until registration is completed where it is required, the assignment may not be fully effective at law. That can create practical problems.
For example, depending on the lease wording and registration position, the assignee may face issues serving a valid break notice, charging the lease to a lender, or assigning the lease again. These are not technicalities you want to discover at the last minute.
Where compulsory first registration applies, the normal registration period is two months from the date of the deed, although HM Land Registry can extend that period in appropriate cases. If registration is missed or delayed, it can create legal and practical problems for the assignee, including issues with future dealings, finance, and break notices.
In addition to Land Registry requirements, most leases require notice of assignment to be served on the landlord after completion. The lease may require a copy of the assignment document to be provided and a fee to be paid for noting the transaction. Sometimes the lease sets out the fee. Sometimes it only gives a minimum fee or refers to a reasonable fee, so it is sensible to confirm the amount before completion.
The effect of an assignment on a lease
Once a lease has been assigned, the assignee steps into the tenant’s position and becomes responsible for the tenant obligations from that point. The outgoing tenant may still remain responsible for existing breaches, unpaid sums, or future liabilities under an authorised guarantee agreement.
Some rights in the lease may also be personal to the original tenant. Break rights are a common example. If a break clause is personal to the original tenant, the assignee may not be able to use it after assignment. This can materially affect the value and flexibility of the lease, so it should be checked before the transaction proceeds.
Any existing guarantee, authorised guarantee agreement, or rent deposit arrangement should also be checked carefully. Some liabilities may fall away on assignment, but others may continue until the assignee assigns again or until the lease ends. Rent deposit repayment will depend on the rent deposit deed and the lease documents.
Assignment v sub-letting
Whether it is better to assign a lease or sub-let it depends on your commercial objective. Are you looking for the cleanest exit available? A temporary income stream? Flexibility to return to the premises? Or a way to dispose of only part of the space?
Assigning the lease means you no longer have your own occupational interest in the property. The assignee becomes the tenant. However, if you enter into an authorised guarantee agreement, you may still remain on the hook if the assignee fails to comply with the lease.
A landlord will not always insist on an authorised guarantee agreement. Even where one is required, it will usually only support the obligations of the immediate assignee. If that assignee later assigns the lease, your authorised guarantee agreement may fall away, depending on the documents and the statutory rules.
Most tenants see assignment as the better option where they no longer need the property and do not expect to need it again.
Sub-letting is different. You remain the tenant under your lease and grant a sub-lease to a sub-tenant. That can give you flexibility, but it also means you remain liable to the landlord for rent and all tenant obligations under the main lease. If the sub-tenant fails to pay, damages the property, or does something that breaches the lease, that can become your problem.
Sub-letting may be worth considering if:
- You want to create an income stream.
- You may want to use the property again later.
- You only want to dispose of part of the property.
- The landlord is unlikely to allow assignment of part.
- The market for a full assignment is weak, but there is demand for short-term occupation.

How much does it cost to assign a commercial lease?
Assigning a commercial lease can involve several costs for the outgoing tenant and the assignee. These costs should be discussed early so everyone knows who is paying for what.
- Legal fees: both the outgoing tenant and the assignee will usually have their own legal costs. Legal fees vary depending on the complexity of the lease, whether landlord consent is needed, how quickly the parties engage, and whether there are issues such as arrears, repair obligations, SDLT, or registration. It’s sensible to get a clear quote at the outset and confirm who is paying the landlord’s legal and surveyor’s costs.
- Landlord’s costs: the landlord will usually expect its legal costs to be paid in connection with the licence to assign. The landlord may also incur surveyor’s costs if it needs advice on repairs, alterations, reinstatement, or the assignee’s proposed use.
- Lease compliance costs: the landlord may require rent arrears, service charge arrears, breaches, or repair issues to be resolved before giving consent. If dilapidations are already a concern, they can become a negotiation point.
- Surveyor’s fees: you may need a surveyor if there are issues around the property’s condition, reinstatement works, market rent, or the commercial terms of the assignment.
- Premium or reverse premium: depending on market conditions, an assignee may pay a premium to take the lease, or they may ask you to pay them a reverse premium if the rent is above market level or the lease contains unattractive obligations.
- EPC and energy efficiency checks: if there is no valid EPC, you may need one before marketing the lease. EPCs usually last 10 years, but you should also check whether the property meets the current non-domestic minimum energy efficiency rules and whether any exemption has been registered.
- Assignee costs: the incoming tenant may need to budget for any premium, rent deposit, advance rent, Land Registry fees, SDLT, search fees, surveyor’s fees, and its own legal costs. For property in England, SDLT may be relevant if the assignee pays a premium or other consideration for the assignment. A return may still be needed even where no SDLT is payable, so this should be checked before completion.
The key point is simple: assignment is not just a signature exercise. Costs can appear from several directions, and they can affect whether the deal is still commercially worthwhile.
How long does the lease assignment process typically take?
The timeline for assigning a commercial lease can range from a few weeks to several months. It depends on the lease, the assignee’s due diligence, how quickly landlord consent is obtained, whether there are repair or arrears issues, and how responsive the parties and their solicitors are.
If the landlord is slow to respond, asks for more information, or requires works to be completed before consent is given, the process will take longer. The same is true if the assignee raises detailed enquiries or wants to renegotiate commercial points.
To avoid avoidable delays, start early. Review the lease, gather the information the landlord is likely to request, check the EPC and registration position, and make sure you understand any conditions that need to be satisfied before completion.
Need advice on assigning a commercial lease?
Assigning a lease can be a practical way to move on from premises that no longer work for your business. But it comes with legal and commercial consequences for everyone involved: the outgoing tenant, the assignee, and the landlord.
Taking advice early helps you understand the consent requirements, likely costs, registration issues, timescales, and any continuing liability after completion. It also helps you avoid agreeing something commercially attractive that the lease does not actually allow.
