Land Option Agreement UK: Planning Permission Guide

What this document is

An option agreement is a binding contract between a landowner and a prospective buyer. The landowner agrees not to sell the land to anyone else for an agreed period, and the buyer pays an option fee for that exclusivity. During the option period, the buyer typically pursues planning permission at their own cost.

If permission is granted within the window, the buyer can 'exercise' the option and require the seller to complete the sale on the terms already written into the contract. If permission is refused, or the buyer decides not to proceed, the option usually lapses and the buyer walks away, generally without recovering the option fee.

This structure is common on sites with development potential, agricultural land near settlements, and plots where value depends heavily on whether consent will be granted. It shifts the planning risk onto the buyer while giving the seller a guaranteed floor if things go ahead.

Option agreements are distinct from conditional contracts and from promotion agreements, and the mechanics matter, which is why careful drafting and independent input are usually worth the investment.

How to use this document

1. Agree the commercial heads of terms first. Before lawyers get involved, the parties normally sketch out the purchase price or pricing formula, the length of the option period, the option fee, any extension rights, and what planning consent would trigger the right to buy. Getting these points clear in writing early saves substantial cost and argument later.
2. Instruct solicitors and carry out due diligence. The buyer's solicitor will investigate title, check for restrictive covenants, rights of way, overage arrangements, mortgages and any third-party interests that could frustrate development. The seller's solicitor will look at the buyer's proposals and negotiate protections for the landowner, including what happens if planning drags on.
3. Negotiate the detailed terms of the option. Key points include how the price is calculated on exercise, whether there is a market value mechanism or discount to reflect planning risk, what planning outcome counts as 'satisfactory', time limits, restrictions on the buyer's planning strategy, and the seller's obligations to cooperate without actively hindering the application.
4. Sign the option agreement and protect it at the Land Registry. Once exchanged, the buyer will normally register a notice against the title so the option binds any future buyer of the land. The option fee is paid, and the buyer can start preparing and submitting the planning application.
5. Exercise the option or let it lapse. If planning permission on acceptable terms is secured within the option period, the buyer serves an exercise notice and the parties move to completion under the pre-agreed terms. If not, the option typically falls away, the notice is removed from the title, and the land is free to be sold or optioned elsewhere.
