What is an Option Agreement?
An option agreement:
- gives the option holder the right (not obligation) to purchase the land
- allows the option holder to exercise the option by serving notice within an agreed option period
- may be exercisable at any time within the period or only once a specific event occurs (commonly, obtaining planning permission)
- either fixes the purchase price at the outset or uses a valuation mechanism (often market value at the time of exercise) to determine price
- is legally binding on both parties for the duration of the option period
While the option holder controls whether or not to exercise the option, the landowner is bound to sell if the option is validly exercised.
Clear drafting is essential to avoid risks, long-term sterilisation of land, disputes over notice requirements, price calculation issues and planning-related uncertainty. Thorough planning and strategic drafting are crucial for both buyers and sellers to mitigate risks.
Why Option Agreements Matter
Option agreements give developers time to:
- Explore viability
- Carry out surveys
- Apply for planning permission
- Secure funding
- Undertake due diligence
For landowners, they provide:
- A potential immediate financial return (option fee)
- Access to planning uplift without bearing application risks
- Potential overage opportunities
But they must be drafted carefully. Poorly structured option agreements can reduce value, create long-term restrictions or fail to protect your commercial position.

Pros and Cons of Option Agreements
Advantages of Option Agreements for Landowners
- Option fee retained whether or not the option is exercised (although it will often be deductible from the price if the developer proceeds with the purchase)
- Developer bears planning risk and cost
- Potential increase in land value once planning permission is obtained
- Ability to negotiate:
- minimum land values
- overage arrangements
- planning obligations
- Access to experienced developers who can drive planning success
Disadvantages of Option Agreements for Landowners
- Land is sterilised during the option period (cannot be sold to anyone else)
- Restrictions on dealing with the land (e.g., leasing, refinancing)
- No guarantee the developer will exercise the option
- Potential long periods of uncertainty if planning is delayed
- Risk of no sale after many years
Professional advice is essential to ensure the option fee, option period and conditions deliver fair value and protect the landowner’s position.

Our Option Agreement Experience
- Acting for neighbouring rural landowners in connection with the grant of long-term option agreements over parts of their land for an innovative gas storage scheme. The option agreements provided for calculation of the sale price by reference to the Retail Prices Index and included provisions for crop loss compensation.
- Acting for a developer in connection with an option to purchase two separate parts of the seller’s title at different prices. The option agreement provided for extensions to the option period to tie in with the timeframes for the developer’s planning application and any appeal or call-in.
- Acting for both landowners and developers in connection with the variation of existing option agreements, for example to extend the option period to allow for planning consent to be determined.

Option Agreements FAQs
What is an option agreement over land?
An option agreement is a legally binding contract giving a developer or other third party the right (but not the obligation) to purchase land or property within a specified period and on agreed terms. If the option is exercised, the landowner is contractually required to sell on those terms.
How long does an option agreement usually last?
Option periods vary depending on the nature of the project. For planning-led developments, they often run for several years to allow time for planning applications, appeals and due diligence. The length is fully negotiable and should reflect the complexity of the development.
Is a landowner obliged to sell if the option is exercised?
Yes. Once the developer serves a valid option notice in accordance with the agreement, the landowner must complete the sale on the agreed terms. This is why it is vital that the agreement is drafted carefully and the sale terms are acceptable from the outset.
Does a developer have to buy the land after entering an option agreement?
No. The developer has a choice. They can decide whether to exercise the option or allow it to expire. This flexibility benefits developers who need time to explore planning and viability without committing to an immediate purchase.
What is an option fee?
An option fee is a payment made by the developer to the landowner in exchange for the right to enter into the option agreement. It is typically non-refundable and is retained by the landowner regardless of whether the option is exercised. In many circumstances, the option fee will be deductible from the ultimate sale price, if the developer proceeds with the purchase of the land.
How is the purchase price decided in an option agreement?
The price can be:
- fixed at the outset
- indexed (e.g., linked to RPI)
- based on market value at the date the option is exercised
- calculated using a valuation mechanism or formula
The appropriate method depends on the nature of the deal and planning risks involved.
Can option agreements be conditional on planning permission?
Yes, this is extremely common. Many option agreements allow the developer to exercise the option only once they have secured planning permission—often for a specific scheme. Agreements may also allow extensions to the option period to accommodate appeals or call-ins.
What happens if planning permission is refused?
If planning is refused or granted subject to onerous conditions, the developer may choose not to exercise the option. They may also have rights to extend the option period or pursue appeals, depending on the terms agreed.
Can a landowner sell the land during the option period?
Usually not, unless the buyer agrees to be bound by the option agreement. Option agreements typically restrict the landowner from selling, charging or dealing with the land while the option remains in force, as the developer needs certainty that the land will be available if the option is exercised.
Can an option agreement be terminated early?
Option agreements are usually not cancellable by the landowner. The agreement will normally run its full term unless both parties agree to bring it to an end or vary its terms.
What is the difference between an option agreement and a conditional contract?
- An option agreement gives the developer the right to buy but does not oblige them to complete, offering flexibility; contrast this with a conditional contract, which requires both parties to proceed with the sale once specified conditions (e.g., planning consent) are satisfied.
- A conditional contract requires both parties to proceed with the sale once specified conditions (e.g., planning consent) are satisfied.
Each structure suits different commercial objectives.
What is an overage agreement, and why might it be used alongside an option?
An overage agreement entitles the landowner to receive additional payments if the land increases in value after the sale, often triggered by planning permission or future development. Many landowners use overage to ensure they benefit from planning uplifts secured by developers.
What happens if the developer serves an invalid option notice?
Serving an option notice incorrectly can invalidate the developer’s right to buy. This can have significant financial consequences. Our property litigation team regularly advises on disputes relating to notice wording, service requirements, deadlines and procedural defects.
Is professional legal advice necessary for option agreements?
Absolutely. Option agreements are complex documents with long-term commercial consequences. Poor drafting can lead to disputes, land being tied up for years without a sale, or missed opportunities for value uplift. Specialist legal advice is essential for both landowners and developers.
