In short
- Nobody can tell you for certain whether land will get planning permission, and most land will not. A few free checks can still rule a lot in or out.
- Where the land sits in relation to the edge of a town or village matters more than almost anything else.
- Green Belt, flooding, wildlife, heritage and access can each be decisive on their own.
- If it still looks promising after these checks, a site appraisal is the sensible next step.
Most landowners ask the same question: could my land be developed? There is no simple yes or no, and anyone who promises one without looking properly is guessing. What you can do is work through the questions planners ask first. Most of the answers are free to find, and together they tell you whether it is worth going further.
National planning policy was rewritten when the government published a new National Planning Policy Framework on 17 August 2026, so some older advice online is now out of date. The checks below reflect the current position.
Nine checks
Where does the land sit in relation to a settlement?
Look at your council’s policies map, which is online as part of its Local Plan. It shows settlement boundaries, the lines drawn around towns and villages. Land inside a boundary usually has a much easier path than land outside it. The August 2026 Framework is stricter outside settlements: proposals are generally expected to fall within a list of exceptions. These include reusing existing buildings, redeveloping previously developed land, housing within about 800 metres (a ten-minute walk) of a well-connected railway station, and meeting an evidenced unmet need. Land next to a settlement edge but outside it is not ruled out, but it needs a clear case.
Is it in the Green Belt or another protected area?
Green Belt is the best known, and it carries extra tests. Our guide to Green Belt land in Essex explains them. Other designations matter too: National Landscapes (formerly Areas of Outstanding Natural Beauty), Sites of Special Scientific Interest, Special Areas of Conservation and ancient woodland. The government’s MAGIC map shows many of these for free.
Is it allocated, or has it been put forward, in the Local Plan?
Land allocated in a Local Plan for housing or other development has already passed the main policy test. Check the plan, and also the council’s land availability assessment, where landowners put sites forward. Sites that have already been assessed and rejected are worth knowing about before you start. If your land is not allocated, that does not end the discussion, but the route is harder and slower.
Has it been built on before?
Previously developed land, often called brownfield, is treated more favourably in national policy, including outside settlements and in the Green Belt. The definition is technical and has exceptions. Land occupied by agricultural or forestry buildings is generally excluded, so a yard full of farm sheds is not automatically brownfield.
Can a safe access be formed?
Almost every site needs a safe way in and out. In Essex the county council is usually the highways authority, and it looks at visibility, road width and speed, and whether the local roads can cope with extra traffic. Check that you own the land you would need to cross, or have rights over it. A strip of land owned by someone else between your site and the road, known as a ransom strip, can stop a scheme or give the strip’s owner a lot of leverage.
Is there a flood risk or a drainage problem?
Use the government’s flood map for planning to see which flood zone the land is in. Land in higher-risk zones faces tougher tests, and even land in the lowest-risk zone can have surface water problems that need careful drainage design. Flooding is a particular issue near the Essex coast and its estuaries.
What about wildlife, trees and biodiversity?
Hedgerows, ponds, old trees and woodland edges can mean protected species, and surveys that can only be done at certain times of year. Most development must also deliver a biodiversity net gain, generally at least 10%. There are exemptions, including one introduced in August 2026 for very small developments of 0.2 hectares or less, which has conditions. Near the Essex coast, residential development typically needs to contribute to the Essex Coast RAMS, and in the Epping Forest and Harlow areas the effect on Epping Forest has to be addressed.
Are there heritage issues nearby?
Listed buildings, conservation areas, scheduled monuments and archaeology can shape what is possible, even on land that is not itself designated, because the setting of nearby heritage assets counts. The National Heritage List for England is searchable for free. This comes up often in Essex villages.
Who owns it, and who else has rights over it?
Get the title from HM Land Registry for a small fee. Look for tenancies (agricultural tenancies can be difficult and expensive to end), covenants that restrict development, mortgages, rights of way, and any existing option or promotion agreement. If there are several owners, they will all need to agree. Take legal advice on these points.
What these checks can and cannot tell you
They can help you rule out land with obvious problems and spot land with a real chance. They cannot tell you whether the council will grant permission, how much could be built, or what the land is worth. Those need a proper assessment and, for value, a chartered surveyor or land agent.
What to do next
- If it looks promising, ask for a site appraisal. It pulls these checks together into a written view and a recommended route.
- If you want the council’s view, pre-application advice is the usual next step.
- If a developer or promoter has approached you, read land promotion and get independent legal advice before you sign anything, especially anything with exclusivity.
Common questions
Does being next to existing houses mean I can build?
No. Being next to housing helps the argument that a site is sustainable, but it does not override Green Belt, flood risk, poor access or a settlement boundary. Each site is decided on its own facts.
Is it worth putting my land forward for the Local Plan?
For larger sites outside settlements, promotion through the Local Plan is often the main route. It can take years and carries cost and risk, so it is worth taking advice first. See land promotion.
How much does a site appraisal cost?
It depends on the site and what is involved. We agree the scope and fee in writing before work starts, and the first conversation is free.
