Insights

Landowners are often presented with a range of transaction structures — from straightforward sales to more complex arrangements such as options or promotion agreements.

Each approach differs in a small number of fundamental ways:

•    Certainty of outcome
•    Timing of receipt
•    Exposure to planning risk
•    Participation in future uplift

Understanding these trade-offs is more important than the detailed legal mechanics.   

​

Outright Sale

​​​​

An outright sale is the simplest structure.
 

Key characteristics:

•    High certainty of outcome
•    Immediate or near-term receipt of funds
•    No exposure to planning risk
•    No participation in future uplift

Value is determined by the land’s current use or short-term potential.

 

Core trade-off:

•    Certainty and speed in exchange for giving up longer-term planning value.
​

Sale with Overage

​

An overage structure combines a current sale with the potential for additional future payments. These payments are typically triggered by defined events, such as:

•    The grant of planning permission
•    A higher-density or more valuable consent

 

Key characteristics:

•    Sale proceeds received upfront
•    Additional, uncertain future payments
•    No direct control over how or when value is realised

 

Core trade-off:

•    Retention of some upside, but without control over delivery or timing.

 

Overage provisions can be complex and outcomes are often less certain in practice than they appear at the outset.  Poorly drafted overages or those with high clawback percentages can inadvertently reduce land value and make future development less likely.  
 

​Option Agreements

 

An option gives a developer or promoter the right — but not the obligation — to purchase land in the future, typically following planning. Two broad forms are common:

 

Fixed price option

• A purchase price is agreed at the outset

• Most of the planning uplift is captured by the developer

 

Market-linked option

• The price is linked to market value following planning (often via a percentage or formula)

• The landowner shares in uplift.

• However, the planning strategy and timing are controlled by the counterparty

 

Core trade-off:

• Planning risk is transferred, but control and value optimisation sit primarily with the party holding the option.

 

​Promotion Agreements 

 

Under a promotion agreement:

•  A promoter funds and manages the planning process

• The land is sold on the open market following planning

• Sale proceeds are shared (after costs) via an agreed percentage

 

Key characteristics: 

• Planning risk is borne by the promoter

• Value is tested through an open market sale

• Both parties are aligned around maximising outcome

 

Core trade-off: 

• Lower certainty and longer timeframe, in exchange for seeking to maximise land value.

​​

A practical way to think about it

 

In simple terms, landowners are choosing between:

• Taking value today (sale) 

• Retaining some future upside without control (overage or options)

• Actively pursuing full planning value (promotion)

​

The appropriate route depends on:

• Time horizon

• Appetite for risk

• Financial position

• Confidence in the planning strategy

 

There is no universally “correct” structure — the optimal approach depends on how certainty, timing and long-term value are balanced.

 

A practical point 

 

Where multiple structures are being considered, the differences in outcome can be difficult to compare on a like-for-like basis.

​

We often help landowners assess how different approaches — sale, option or promotion — are likely to perform in practice, and how relatively small structural differences can have a material impact on net land value.
