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 40 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.

Why Choose Farnworth Rose for Overage Advice?

When you instruct Farnworth Rose on an overage matter, you are choosing a team that understands both the legal detail and the commercial realities behind the deal. Overage clauses often look straightforward at first glance, but the real value lies in the drafting. A poorly drafted provision can leave a seller without meaningful protection, or leave a buyer tied into terms that are unclear, unworkable or damaging to future development plans.

We are committed to delivering value that protects your position both now and in the future. Our Commercial Property Solicitors take the time to understand what you are looking to achieve with an overage agreement. This may include securing a fair return on future uplift or limiting your exposure to additional payments. We also focus on protecting development viability and ensuring the land remains marketable and financeable.

Our approach is defined by the standards we set across every overage matter we handle:

  • An experienced and respected commercial team that understands both legal complexity and commercial reality

  • Transparent pricing with detailed, upfront costs and no hidden surprises

  • Direct access to a responsive solicitor who is committed to delivering a high standard of service

  • Strategic, outcome-focused support designed to protect your position at every stage

We do not believe in one-size-fits-all drafting. Every overage agreement must reflect the specific circumstances of the deal and the objectives of the parties involved.

Our specialist solicitors are available to discuss your matter in a way that suits you, whether that means meeting in person or speaking remotely. Wherever you are based, we provide the same high level of service, ensuring you have the clarity, confidence and support needed to move forward.

Why Legal Advice Matters During an Overage Agreement?

Overage agreements are often used where there is uncertainty about the future value of land or property, particularly where that value may increase significantly if a defined event takes place later. In many cases, that trigger 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.

Because overage is designed to deal with future possibilities rather than present certainty, the drafting needs to be handled with great care. A seller may agree to sell land at a price that reflects its current position, while wanting protection if the land becomes much more valuable later. Legal advice is essential to ensure the agreement clearly defines the trigger event, the payment mechanism and the protections needed so that the arrangement works properly in practice and does not give rise to avoidable disputes.

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.

+ What Is An Overage Agreement?

An overage agreement is a contractual arrangement that allows a seller to benefit from any increase in value after a sale caused by a defined future event. In many cases, that trigger 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 where land or property has future development potential that is not yet reflected in its current value, such as where planning permission has not yet been secured or redevelopment may become possible later. It helps bridge the gap between the price a buyer is prepared to pay now and the future value a seller may otherwise lose if the site becomes significantly more valuable after the sale.

+ What Should An Overage Agreement Include?

An overage agreement should clearly set out what event will trigger payment, how long the overage period will last, and how the payment will be calculated. It should also define matters such as permitted deductions, valuation assumptions and any security arrangements carefully, as unclear drafting can lead to disputes or make the agreement difficult to enforce.

+ How Is Overage Protected?

Overage is usually protected by legal mechanisms such as a restriction on the title at HM Land Registry, often supported by a deed of covenant from any future owner. In some cases, additional security such as a legal charge may also be used, depending on the structure of the transaction and the level of protection required.
