Sell land with planning permission in Isleworth
We buy land with planning permission across Greater London. In Isleworth, as everywhere, the offer depends on the land itself: its access, its planning prospects and what can sensibly be built.
Land with planning permission has consent from the local planning authority to build a specific development, either in outline (the principle) or in full (the detailed design). We buy consented sites directly, check the permission and its conditions, and make an offer you can accept without marketing the land.
- Free appraisal and written offer
- Figures explained, so you can check them
- Independent advice encouraged

Where Isleworth sits
From Isleworth, it's 1 mile to Hounslow and 2 miles to Heston. We buy land across that whole stretch of Greater London, not only within the town.
Land is scarce and mostly brownfield. The outer boroughs contain Metropolitan Green Belt and metropolitan open land, both closely protected.

Consented land sells on detail. We read every condition and obligation so our offer is based on the scheme as approved, not on guesswork.
How we arrive at a figure for land in Greater London
Type of permission
Full permission carries less risk than outline, which still needs reserved matters approval.
Time left on the permission
A permission close to expiry may need a quick start or a fresh application, and that affects price.
Pre-commencement conditions
Conditions that must be discharged before building starts can add surveys, cost and delay.
Section 106 and CIL
Affordable housing and financial contributions come straight off what a buyer can pay.
Four routes to a sale
Outright purchase
The usual route for consented land: agree a price, then exchange and complete.
Subject-to-planning sale
Useful if you want us to improve or renew the permission before completion.
Option agreements
Rarely needed once consent exists, but can suit phased sites.
Joint ventures
An option if you would like a share of the profit from building the homes.
How a sale works
Send us the address
A postcode, a plan or a what3words location is enough to start.
We do the homework
We read the title and planning record and check flood risk and access.
You get a written offer
With the main figures behind it, so your adviser can check it.
The legal work
Your solicitor and ours handle the contract through to completion.
Planning and legal points for land in Greater London
Planning framework
Planning decisions in England follow the National Planning Policy Framework, revised in August 2026, and the local plan, prepared by the council or, in a national park, the park authority. Plans are reviewed periodically, which is when new housing sites are usually allocated.
Agricultural buildings (Class Q)
In England, Class Q permitted development can allow some agricultural buildings to become homes through prior approval, within limits on size and number of homes.
Section 106 and CIL
Larger schemes often need a Section 106 agreement for affordable housing or contributions, and councils that have adopted the Community Infrastructure Levy charge it per square metre of new floorspace.
Common problems, and how we handle them
The conditions look onerous
Some conditions are routine and some are expensive. We price each one so you can see what is driving the offer.
The Section 106 makes the scheme unviable
If costs have moved since consent, a viability review or a variation may be possible. We will tell you if we think that is realistic.
Useful to send us
- Your title number, if you know it
- Details of any tenants or grazing agreements
- Photos of the land and its access
- How soon you'd ideally like to sell
What people ask us about land with planning permission
How long does planning permission last?
In England, full planning permission usually requires work to start within three years, and in Wales within five, unless the decision notice says otherwise. Outline permissions have separate time limits for reserved matters. The decision notice sets out the exact dates.
Do you pay more for full permission?
Usually, because there is less risk and less work before building can start. How much more depends on the conditions and obligations attached.
Can I sell a plot with prior approval for a barn conversion?
Yes. Prior approvals are time limited and have their own rules, so we check the approval and the building before making an offer.
Do you cover the villages around Isleworth?
Yes. Villages between Isleworth, Hounslow and Heston often have the kind of edge-of-settlement land we're looking for.
