Overage Agreement Solicitors
If you are selling land or property with future development potential, or acquiring a site where value may increase later, an overage agreement can be one of the most important parts of the deal. Also known as a clawback or uplift arrangement, overage gives the seller the right to share in a future increase in value, most commonly where planning permission is granted after the sale.
With over 35 years of experience in commercial property matters, Farnworth Rose advises landowners, developers, investors and businesses across Lancashire and beyond on complex overage agreements.
Overage can be highly effective when it is properly structured. It can also create uncertainty, delay and costly disputes if the wording is unclear or the agreement does not properly protect the parties’ interests. Whether you are a landowner looking to secure future value, a developer negotiating workable terms, or an investor assessing risk, you need legal advice that is both technically strong and commercially sensible.
At Farnworth Rose, our Commercial Property Solicitors advise landowners, developers, investors and businesses on all aspects of overage agreements. We provide strategic advice on drafting, negotiating and enforcing overage provisions, always with your wider commercial goals in mind. We work carefully to identify future risks, define the right trigger events, and ensure the agreement is structured in a way that is practical and tailored to your transaction.

What Is an Overage Agreement?
An overage agreement is a contractual arrangement that allows a seller to receive an additional payment after a property or parcel of land has been sold, if a specified event happens in the future that increases its value. In many cases, that event is the grant of planning permission, although overage can also be linked to implementation of planning permission, disposal of the land, or other agreed development milestones.
In simple terms, overage is designed to deal with uncertainty. A seller may agree to sell land today at a price that reflects its current position, while recognising that the land could become significantly more valuable later. Rather than trying to predict that future value at the outset, the parties can agree that if the value increases because of a defined future event, the seller will receive an agreed share of that uplift.
When Is Overage Used?
Overage is commonly used in land transactions, development sales and strategic disposals where the future potential of a site has not yet been fully realised. It is particularly relevant where planning permission has not yet been secured, or where the buyer is taking on the cost, delay and risk of promoting or developing the land.
It is often used where the current value of land or property does not reflect what it could be worth in the future if a more valuable use becomes possible. In those circumstances, overage can help bridge the gap between the price a buyer is prepared to pay now and the value the seller may otherwise lose if the site is later enhanced.
A typical example is agricultural land on the edge of a village or town, where there is a possibility of future residential development. A landowner may be willing to sell at its current value, while wanting protection in case the buyer later obtains planning permission for housing and the land becomes significantly more valuable.
Overage is also frequently used in relation to brownfield land or former commercial premises with redevelopment potential. For example, a seller may dispose of an old industrial site, office building or storage yard, recognising that the buyer may later secure planning permission for residential, mixed-use or higher-value commercial development. In those circumstances, overage can ensure the seller shares in that future uplift.
Another common scenario is where land is sold to a developer or promoter at a stage when the planning position is still uncertain. The buyer may be taking on the cost, delay and risk of promoting the land through the planning system, while the seller wants to retain the benefit of some of the increased value if that process succeeds. Overage can help bridge that gap by allowing the deal to proceed now, while providing for an additional payment later if a defined trigger event occurs.
For sellers, overage can be an important safeguard against losing out on future value. For buyers, it can be a practical way of agreeing a deal where potential exists but has not yet been realised. Because the parties’ interests are different, overage provisions need to be drafted carefully so the arrangement is fair, workable and commercially realistic.
What Should an Overage Agreement Include?
The success of any overage arrangement depends on precise drafting. The agreement should clearly define the event that triggers payment, the period during which the right applies, and the method used to calculate the amount due.
The trigger event is critical. In some cases, overage is triggered on the grant of planning permission. In others, it is triggered only when that permission is implemented, when development begins, when units are sold, or when the land is disposed of at a profit. Choosing the wrong trigger can create serious problems. A trigger that is too early may produce unfair results or undermine viability. A trigger that is too late may weaken the seller’s protection or make enforcement more difficult.
The overage period also needs careful thought. If it is too short, the buyer may simply wait until the period expires. If it is too long, the agreement may restrict future dealings with the property or create difficulties with funding and onward sale. The appropriate term will depend on the nature of the site, its planning prospects and the parties’ commercial objectives.
The calculation mechanism must also be clearly defined. In many cases, overage is based on a percentage of the uplift in value, after taking account of the base value and certain agreed costs. However, the drafting must make it absolutely clear what is deductible, how value is assessed, and what assumptions are to be made. This is often where disputes arise, especially if professional fees, planning costs, infrastructure costs or other deductions are left open to interpretation.
How Is Overage Protected?
One of the most important legal issues with overage is ensuring that the seller’s right is properly secured. An obligation to make a future payment does not automatically bind successors in title in the way many clients assume, so overage arrangements must be carefully structured to remain effective if the land is sold on.
One common form of protection is a restriction on the title at HM Land Registry. This can be used to prevent a future disposition of the property unless certain conditions are met, such as the new owner entering into a deed of covenant to observe the overage obligations. This is often an effective and commercially workable solution, particularly where the land may change hands during the overage period.
In some cases, stronger security may be considered, such as a legal charge. This can offer significant protection, but it may also create practical issues, particularly if the buyer requires development finance and a lender insists on priority security. The appropriate protection will depend on the overall structure of the transaction and the bargaining position of the parties.
Our role is to make sure the security provisions are not treated as an afterthought. A well-drafted overage clause can still fail to deliver the protection intended if the enforcement mechanism is weak or impractical.
How We Help with Overage Agreements
Whether you are selling land or acquiring it for development, overage can play a critical role in shaping the overall value and success of your transaction. The key is ensuring that the agreement reflects your commercial objectives while remaining clear, workable and legally robust.
We also look beyond the headline percentage. In many cases, the real value lies in the detail, including how uplift is calculated, what deductions are allowed, what information you are entitled to receive and how the agreement operates if the land is sold on or developed in phases. Our aim is to provide you with a practical agreement that reflects the true value of the opportunity you are giving up while reducing the risk of disputes later.
If you are buying land subject to overage, it is essential to understand exactly what obligations you are taking on. Poorly drafted or overly restrictive clauses can affect development viability, delay funding and create long-term risk that was not properly factored into the deal.
We work closely with buyers and developers to negotiate terms that are fair, clear and commercially workable. This may involve refining trigger events, limiting the overage period, clarifying how payments are calculated or ensuring the agreement aligns with funding arrangements and development timelines.
Overage should never be considered in isolation. It must fit within the wider transaction, your development strategy and your long-term commercial objectives. Our role is to ensure that it does.
Frequently Asked Questions for Overage
+ What Problems Commonly Arise with Overage?
Common problems include unclear trigger events, disputes over how uplift is calculated, and arguments about what costs or deductions can properly be taken into account. Issues also arise where the overage agreement does not deal clearly with repeat planning permissions, onward sales, connected-party transactions, or how the seller’s rights will be protected if the land changes hands.
+ Do Overage Agreements Have Tax Implications?
Yes, overage agreements can have important tax implications, including potential SDLT consequences for buyers and capital gains tax issues for sellers. Because the tax treatment will depend on how the deal is structured, it is important to take legal and tax advice early so the agreement works as intended.
+ Should I Buy Property With An Overage Clause?
You can buy property with an overage clause, but you only should if you fully understand how it works and how it may affect the value, development potential and future saleability of the property. Before proceeding, it is important to take legal advice on the trigger events, payment terms, duration and any restrictions so you can assess the risk and negotiate workable terms.
+ Can An Overage Be Removed?
An overage can sometimes be removed, but this usually requires agreement between the parties and may involve a negotiated payment or formal release. Whether it can be removed easily will depend on how the overage was drafted, how it is protected on title, and whether the beneficiary is willing to vary or discharge it.
+ What Can Trigger An Overage Payment?
An overage payment is usually triggered by a specific event set out in the agreement, most commonly the grant of planning permission, implementation of that permission, or a future sale of the land at an increased value. The exact trigger must be clearly defined, as vague drafting can lead to disputes or unexpected liabilities later.
+ How Is Overage Calculated?
Overage is usually calculated as a percentage of the increase in value that arises when a specified trigger event occurs, such as the grant of planning permission. The agreement should clearly state how that uplift is measured, what deductions are allowed, and how the payment is to be assessed, as this is one of the most common areas for dispute.
+ How Long Does An Overage Agreement Last?
The length of an overage agreement depends on what the parties negotiate, but it will usually run for a fixed period set out in the contract, often several years. The term needs to be long enough to protect the seller’s position, while still being commercially workable for the buyer and not creating unnecessary difficulties for future sale or funding.
+ What Happens If The Land Is Sold On During The Overage Period?
If the land is sold on during the overage period, the agreement should ensure that the overage obligations continue to bind the property and any future owner where appropriate. This is usually dealt with through title restrictions and deed of covenant arrangements, helping to protect the seller’s right to receive payment if a trigger event occurs later.
+ Can Overage Affect Development Finance Or A Future Sale?
Yes, overage can affect both development finance and a future sale, particularly if the terms are unclear or the security arrangements are too restrictive. Lenders and future buyers will want to understand how the overage works, when payments may become due, and whether it could interfere with the value, marketability or development of the land.
