Sell Land Without Planning in Isleworth
Selling a site in Isleworth before planning comes down to who carries the risk and the cost of the application. Land to Homes looks at local planning policy, access and constraints, then sets out which deal fits: a direct purchase, subject to survey, title and contract, a conditional contract, or a longer-term option or promotion.

What we offer in Isleworth
Overage protects the upside
If you sell now, an overage clause can entitle you to a further payment if a more valuable permission is granted later. We explain how triggers, duration and security are usually set out.
Local plan timing
Councils review their development plans periodically and invite landowners to put sites forward. We check where your council is in that cycle, because it can matter more than any single application.
Constraints checked first
Flood risk, access, heritage, ecology, protected trees and landscape designations can each decide whether planning is realistic. We look at all of these before discussing any deal or price mechanism with you.
Conditional contracts
Contracts are signed now, but the sale only completes if a satisfactory planning permission is granted by a longstop date. The price is usually fixed, or set by an agreed formula, when the contract is signed.
Planning and land rules in Isleworth
Selling development land in Isleworth usually starts with heads of terms, a short written summary of price, conditions and fees, before solicitors draft the contract. In England the sale becomes binding on exchange of contracts and finishes on completion, with the title then registered at HM Land Registry. The buyer normally pays Stamp Duty Land Tax. On option and promotion agreements with Land to Homes, your reasonable legal fees are covered, with the amount agreed in the heads of terms.
In England, the starting point is the Local Plan and the National Planning Policy Framework. Councils assess land put forward in a housing and economic land availability assessment. Smaller housing-led sites can apply for Permission in Principle to test whether the location is acceptable, and some Green Belt land may now be assessed as grey belt.

Your questions answered for Isleworth
What if my land has been refused planning before?
A previous refusal is useful evidence, not necessarily the end of the story. Policy changes, new local plans and a different scheme can lead to a different outcome. We read the refusal reasons and any appeal decision before giving a view on whether a fresh approach is realistic and worth the cost.
Should I apply for planning permission myself before selling?
You can, but an application costs money in surveys, reports and fees, and a refusal can make the land harder to sell. A scheme designed by someone who does not intend to build may also not suit housebuilders. Many landowners prefer a partner who carries the cost and risk of planning instead.
What is a subject to planning contract?
It is a contract where both sides commit now, but the sale only completes if a satisfactory planning permission is granted. It sets a longstop date, defines what counts as satisfactory and usually says who controls the application. If permission is not granted by the longstop date, either side can normally withdraw without penalty.
What is hope value?
Hope value is the extra amount a buyer will pay above a site's existing use value because there is a realistic prospect of planning permission. The stronger the prospect, and the sooner permission could realistically come, the higher the hope value tends to be. It is lower than the value with permission, because the buyer carries the planning risk.
