Overage clauses are vital in many property transactions, especially when a property holds potential for future development or significant value increase after the sale.
These clauses allow the seller to benefit from any future enhancement in the property’s value while giving buyers the flexibility to develop or improve the property. Essentially, an overage clause ensures that if the property’s value increases due to certain conditions, such as obtaining planning permission or completing a development, the seller receives a portion of the profit.
This type of clause is common in land transactions, where future use or development significantly affects value. Without an overage clause, sellers might miss out on potential profits linked to the property’s future development. Buyers, on the other hand, need to approach these clauses carefully to ensure they align with their investment strategies and future plans. Structuring and enforcing these clauses properly is key to avoiding disputes and maintaining transparency between both parties.
What is an overage clause?
An overage clause, also called a “clawback” or “uplift” clause, is a provision in a sale agreement that entitles the seller to additional payments if the property’s value rises after the sale due to specific events. These events often include obtaining planning permission, changing the property’s use, or completing developments that raise the property’s market value.
For example, a buyer might purchase land valued for agricultural use. If they later secure planning permission for residential development, the land’s value could significantly increase. In this case, the overage clause would entitle the seller to a portion of the profit from this increase in value.

Overage payments may be triggered by:
Planning permissions
If the buyer secures permission for a more profitable use, such as converting agricultural land into residential or commercial property, the seller may be entitled to a payment.
Property sale
If the buyer sells the property at a higher price after developing it, the seller could receive a percentage of the profit.
Development completion
Once a specific development project is finished and the property’s value rises, the overage clause could require the buyer to compensate the seller for the enhanced value.
These clauses are particularly common in land deals with development potential and sectors such as residential housing, retail, and mixed-use projects.
Managing overage clauses
Given the financial implications, it’s essential that both parties fully understand the terms of an overage clause. Properly drafting the clause ensures clarity on the conditions that trigger an overage payment and how the payments will be calculated. A well-structured clause will define the specific events or milestones, such as obtaining planning permission or completing a development, that will lead to a payout. This prevents confusion and potential disputes down the line.
In addition to drafting the agreement, monitoring and enforcing overage clauses are crucial steps. It is important to keep track of any developments or changes that may trigger an overage payment. Registration with the Land Registry can provide additional legal safeguards, ensuring the clause remains enforceable in future transactions.

Key considerations for buyers and sellers
For sellers, overage clauses offer a way to ensure they don’t miss out on future value increases after the sale. For buyers, however, it’s important to fully understand the financial obligations an overage clause imposes and plan accordingly. The agreement should clearly define the point at which payments become due and how those payments will be calculated.
Both parties should ensure that the overage clause reflects the specifics of the transaction, the property’s development potential, and market conditions. Legal clarity is essential, particularly concerning triggers for payments and the formula for calculating the uplift.
How our solicitors can help with overage clauses
Our solicitors can assist with drafting overage agreements that protect both buyers’ and sellers’ interests. These agreements often include specific conditions triggering post-sale payments, such as new planning permissions, changes in land use, or a higher resale value. With legal advice, developers can optimise profits on projects likely to appreciate due to market growth.
Drafting overage clauses
Our team of commercial property solicitors offers expert legal advice to developers, buyers, and sellers. Drafting a clear, legally sound overage clause is essential to avoid future disputes. Key elements of an overage agreement include its duration (typically 5–25 years), conditions triggering payment, payment calculation methods, and termination of the agreement. A well-structured clause reduces the likelihood of misunderstandings or legal complications down the line.
Securing overage clause payments
Securing overage payments is crucial to protecting your financial interests. Our solicitors can guide you through various methods, such as placing restrictions on future property dealings, retaining ransom strips, or selling the property as a leasehold to ensure ongoing overage obligations. Proper security can prevent disputes and legal complications, ensuring smooth transactions.
Overage clause disputes
Overage clause disputes may arise when terms are vague or unclear, leading to confusion between buyers and sellers. Poorly drafted clauses can cause sellers to lose expected payments, and unclear obligations may leave room for legal loopholes. Our solicitors assist in resolving disputes, helping clients assess their legal positions, negotiate solutions, and protect their financial interests. Clear agreements help avoid complications and protect against significant financial losses.

Frequently asked questions about overage clauses
What is contract overage?
A contract overage is an agreement where the buyer of land agrees to pay the seller an additional sum if a future event increases the land’s value. This extra payment is triggered by events like securing planning permission or other developments that enhance the property’s worth.
What is an example of overage?
An example of overage is when agricultural land is sold with a clause allowing the seller to receive additional payment if the land is later rezoned for residential or commercial use. This ensures the seller benefits from any future increase in the land’s value due to rezoning.
How long does an overage clause last?
The duration of an overage clause varies, typically lasting between 5 to 25 years, depending on the anticipated property development timeline. Short-term developments often involve clauses lasting 5–10 years, while longer-term projects may require a 25-year clause. Terms should be clearly stated, and it’s always advisable to seek legal advice before agreeing.
What is the method for calculating overage payments?
Overage payments are calculated based on the increase in property value, often determined as a percentage of the uplift. The percentage is agreed upon when drafting the overage clause, typically ranging from 25–50%. Open market valuations, with and without planning permission, are often used to ensure fair comparisons, excluding inflation factors.
How to get around an overage clause?
To remove an overage clause, a Deed of Release is required from the party benefiting from the clause. The details of the beneficiary and the original overage terms are typically found in the Overage Deed or Transfer Deed, outlining how the clause can be released.
