A demised property is the part of a commercial property that a tenant is given the legal right to occupy under a lease. In simple terms, it is the space you are renting from the landlord for your business.
This may sound straightforward, but in commercial leases, the detail matters. The demised property is not always limited to the room, unit, shop, or office you use day to day. It can include other parts of the building or land, depending on how the lease is written.
For business owners, this is an important point to understand before signing a lease. The way the demised property is defined can affect your repair duties, service charge costs, rights of access, ability to make changes, and what you must hand back to the landlord when the lease ends.

What Does Demised Property Mean?
In a commercial lease, the demised property is the area that the landlord grants to the tenant for the length of the lease.
For example, if you rent a shop, the demised property may include the shop floor, back room, toilet, shopfront, windows, doors, and internal fittings. If you rent an office, it may include the office suite itself, but not the shared entrance, lift, stairs, corridors, or toilets.
The lease should describe the property in writing. It may also include a lease plan showing the area included. This plan is important because it helps confirm the exact space you are taking on.
A tenant should not rely only on the property address or what they saw during a viewing. The legal position comes from the lease itself.
Why the Definition of Demised Property Matters
The definition of demised property matters because it helps decide what you are responsible for.
If something forms part of the demised property, the lease may make you responsible for repairing, maintaining, decorating, or replacing it. This could include parts of the property that you did not expect to be responsible for.
For example, a tenant may assume the landlord will deal with windows, doors, pipework, flooring, or external areas. But if the lease includes those items within the demised property, the responsibility may fall on the tenant.
This can lead to disputes. It can also lead to unexpected costs, especially at the end of the lease when the landlord checks the condition of the property.
What Can Be Included in a Demised Property?
Every commercial lease is different. Some leases define the demised property narrowly. Others give the tenant responsibility for a wider area.
A demised property may include the internal space only. It may also include:
- Internal walls
- Floors and ceilings
- Doors and windows
- Shopfronts
- Toilets and staff areas
- Basements or storage rooms
- Service pipes, cables, or meters
- Loading bays
- Yards
- Parking spaces
- External areas linked to the premises
This is why the wording needs to be checked with care.
A small detail in the lease can make a big difference. For example, if the lease includes a yard or loading area, the tenant may need to maintain it. If the lease includes a shopfront, the tenant may need to repair or replace it if it becomes damaged.
Demised Property and Shared Areas
Many commercial buildings include shared areas. These are spaces used by more than one tenant.
Common examples include entrances, corridors, lifts, staircases, shared toilets, car parks, bin stores, and service yards.
These areas may sit outside the demised property. The landlord may keep control of them, while giving tenants the right to use them.
However, this does not always mean the tenant pays nothing towards them. The lease may require the tenant to contribute through a service charge. This service charge may cover cleaning, lighting, repairs, security, management, maintenance, or other costs linked to shared areas.
Before signing a lease, you should understand which areas are included in your demised property, which areas are shared, and what costs you may need to pay.
Repair Responsibilities and Demised Property
Repair duties are one of the main reasons the demised property clause matters.
Commercial leases often place repair obligations on tenants. If your lease says you must keep the demised property in good repair, you need to know exactly what that includes.
This could mean you are responsible for the internal condition of the unit. It could also mean you are responsible for doors, windows, shopfronts, fixtures, fittings, flooring, or other parts of the property.
In some leases, the tenant may even take on responsibility for structural or external parts. This can create a much larger financial risk.
For example, if a roof, wall, external surface, or service pipe forms part of the demised property, the tenant may face repair costs they did not expect.
This is one reason why business owners should get a commercial lease reviewed before signing.
What If the Property Is Already in Poor Condition?
A common issue arises when a tenant takes on a property that already has damage or defects.
The property may have worn flooring, cracked walls, damp, damaged windows, poor decoration, or old fixtures. If the lease says the tenant must keep the property in repair, the tenant may become responsible for putting those issues right, even if they existed before the lease started.
A schedule of condition can help protect the tenant.
A schedule of condition records the state of the property at the start of the lease. It usually includes photographs and written descriptions. If the lease is drafted correctly, the tenant’s repair duty can be limited by reference to that schedule.
This means the tenant may only need to return the property in the same condition as shown in the schedule, rather than improving it.
Without this protection, the tenant may face a higher repair burden.
Can You Make Changes to a Demised Property?
Many tenants need to alter a commercial property so it works for their business.
A shop may need display fittings. A salon may need treatment rooms. A restaurant may need kitchen works. An office may need partitions, flooring, cabling, or new lighting.
However, tenants cannot usually make changes freely. Most commercial leases include rules about alterations.
Some changes may need the landlord’s written consent. Structural changes may be restricted or refused. The lease may also require the tenant to remove alterations at the end of the lease and return the property to its previous layout.
If you make changes without consent, you may breach the lease. This can cause problems during the lease and when you leave.
Before carrying out works, you should check what the lease allows.
What Happens at the End of the Lease?
At the end of the lease, the tenant usually has to return the demised property in the condition required by the lease.
This can include repairing damage, redecorating, removing signage, taking out alterations, clearing the premises, and handing the property back in the agreed condition.
If the landlord believes the tenant has not met their obligations, they may bring a dilapidations claim. This is a claim for the cost of putting the property into the condition required by the lease.
Dilapidations claims can be expensive. They can also come as a shock to tenants who did not fully understand their responsibilities when they signed the lease.
The best time to deal with this risk is before the lease is signed, not when the lease is ending.
Why You Should Check the Lease Before Signing
A commercial lease is a serious legal commitment. It can affect your business for years.
Before signing, you should understand:
- What is included in the demised property
- What areas are excluded
- What shared areas you can use
- What repair duties you are taking on
- What service charges you may need to pay
- What changes you can make
- What condition you must return the property in
- Whether a schedule of condition is needed
This gives you a clearer view of your legal and financial responsibilities.
It can also help you negotiate better terms before you commit.
