Can My Land Be Built on? How to Find Out for Free, Step by Step

Whether land can be developed comes down to three kinds of question. The first is policy: what the council's local plan and the national rules say about building in that spot. The second is physical: whether the land floods, carries a protected habitat, sits beside a listed building or has no safe way in. The third is practical: whether homes there would be worth building once roads, drainage, affordable housing and the rest are paid for. A landowner can answer most of the first two from a kitchen table. The third needs professional work, and it is where a home check stops.

The table sets out the checks in order, with the free tool for each and the limit of what it can tell you. Keep to the order: there is little point studying the planning history of a field that sits wholly in a flood zone.

The local planning authority decides, and for housing in most of England that is your district or borough council, or a unitary council where there is only one tier. Where there are two tiers, the county council is still involved: it is the highway authority and deals with minerals and waste, but the decision on homes rests with the district.

Start by confirming the right council, because parish, district and county boundaries do not always follow the lines people expect, and a field on the edge of a town can sit in a different district from the town itself. The government's search the register of planning decisions service takes a postcode and points you to the council, and notes that plans for all new developments that need planning permission are made public by the council. If your field has no postcode, use the postcode of the nearest house on the same road.

1. Find the council. Enter the nearest postcode in the GOV.UK service and follow the link to the council's own website.
2. Find its planning policy pages. Councils usually call them planning policy, local plan or development plan. This is where the plan, its policies map and its evidence documents live.
3. Find its planning application search. This is a separate part of the site, usually under planning applications or public access, and it is where the history of your land and its neighbours is held.
4. Note the neighbouring council. Near a district boundary, homes and roads planned just across the line change the picture around your field.

A local plan is the council's document setting out where homes and other development should go, and the policies map is the drawing that goes with it. Every line, wash of colour and hatched area refers to a numbered policy in the written plan, and the key says which one. Find your field, then work through the key looking for each of these.

• Green Belt. Usually a wash of colour across the countryside around a large town or city. If it covers your land, the next section applies.
• Designations. Conservation areas, Local Green Space, and landscape and wildlife designations, each tied to a policy of its own.
• Land kept for other uses. Employment land, open space or the line of a future road, which the plan protects from being built over for homes.
• A neighbourhood plan area. Where a parish has made a neighbourhood plan, it forms part of the development plan and may have its own map.
• An allocation or a settlement line. Both matter a great deal, and each has a guide of its own.

Whether your field is inside, on the edge of or away from a town or village decides which national policy applies, S4 inside or S5 outside, and our guide to settlement boundaries shows how to read that line and what each side of it means. If the map shows an allocation on your land, or you want to know whether the council has assessed it as a possible housing site, the guide to checking the local plan and the SHLAA explains each status and how to find your entry.

A national map now pulls many of these layers together. The government's Planning Data platform, built by the Ministry of Housing, Communities and Local Government, publishes datasets for Green Belt, conservation areas, listed buildings, tree preservation zones, Article 4 direction areas, flood risk zones, ancient woodland and scheduled monuments, and shows them on a single map. It makes a quick first look, with two limits. The map itself warns that the data may be incomplete and not yet cover all of England, and the Green Belt dataset describes itself as a snapshot in time, built from councils' annual returns, which does not show boundary changes made since. Where the two differ, rely on the council's own policies map.

Two cautions. No colour on your land is not a green light: an unmarked field in open countryside is usually land where the plan does not expect homes. And the map shows the adopted plan, which may be several years old with a new one under way; the council's planning policy pages usually say how far a new plan has got.

If the policies map shows your land in the Green Belt, a different and stricter set of policies applies. The national framework is explicit that policy S5 does not apply to development proposals in the Green Belt or on land designated as Local Green Space. Homes there have to fit one of the routes the Green Belt chapter of the framework allows.

The exception that matters most to landowners is grey belt, a category of Green Belt land defined in the framework's glossary by whether it has been developed before and how much it does for three of the Green Belt's purposes. Whether a field qualifies depends on how it sits in the landscape, what lies on its edges and how the council has scored it in any Green Belt review, and housing on grey belt has its own need test and the Golden Rules on affordable housing and infrastructure. All of that is set out, with a self-check of its own, in our guide to grey belt land.

Flood risk is often the first hard barrier, and it is the easiest to check. The Environment Agency's flood map for planning is the official tool. Its own front page says it lets you find out if you need a flood risk assessment as part of a planning application, download a printable flood map for planning, and order detailed flood risk data. Search by the nearest postcode or place name, move the map to your field and read which flood zone covers it.

Look at the whole field rather than the corner by the gate. Many fields are partly in a flood zone along a brook or ditch and dry everywhere else. That is a very different position from a field wholly in the highest risk zone. Rain running off the land, and water lying in hollows after a storm, matter as well, both to the council and to whoever designs the drainage, and our flood risk guide explains how those risks are judged.

• Which flood zone covers most of the field, and which covers the rest?
• Is the access route to the road in a higher zone than the field itself?
• Does water lie in a low corner or along a hedge after heavy rain?
• Has the field flooded in your own memory, even if the map does not show it?

The map tells you the zone, which is a measure of probability. It does not tell you how many homes a layout could fit on the dry part, what drainage the site would need, or whether the council would accept homes there after its sequential test. What each zone means, the tests that follow and how a partly flooded field can still work are explained in our guide to flood risk and development land.

For wildlife and landscape, the main tool is Defra's MAGIC map, which stands for Multi-Agency Geographic Information for the Countryside. It describes itself as providing authoritative geographic information about the natural environment from across government, drawing on organisations including Natural England, the Environment Agency, Historic England and the Forestry Commission. Natural England's guidance tells owners they can use the MAGIC map system to check if land is within a SSSI, a Site of Special Scientific Interest: zoom in to your location, choose the identify tool and click the site to see its name. Natural England's designated sites service then gives the boundary, the reasons for designation and the condition of each site.

For heritage, Historic England's Search the List covers the National Heritage List for England: listed buildings, scheduled monuments, protected wrecks, registered parks and gardens, and battlefields, with a map search to find them near your land. Conservation areas are designated by the council and appear on its policies map or its conservation pages. Tree preservation orders are made by the council too.

One service brings several of these together for a single property. HM Land Registry's search for local land charges is free to search, with £15 payable only if you want an official search certificate. Local land charges include planning conditions, tree preservation orders, conservation areas and listed buildings. Not every council has moved its register onto the service yet, and where yours has not, the council holds it.

National Landscapes are the areas formerly called Areas of Outstanding Natural Beauty; Lincolnshire County Council's announcement records the new name taking effect from 22 November 2023. Older maps and plans still use the old name, so look for both.

These maps show what has been designated, not what an ecologist would find on a walk round the field, such as newts in a pond or bats in a hedgerow tree. Seasonal surveys find those, and they change layouts far more often than they stop schemes.

1. Search your own land first. Use the map view if the council's search has one, since old applications are often filed under a farm name or a neighbouring address rather than a postcode.
2. Widen the search to a mile or so around. Look for applications for homes on fields like yours at the edge of the same village or the next one.
3. Open the decision notice and the officer's report. The decision notice gives the reasons for refusal in numbered points. The officer's report, sometimes called the delegated report or committee report, explains how the council weighed the case.
4. Check for an appeal. If a refused scheme went to appeal, the inspector's decision is the most useful document of all, because it is an independent view of the same policies.
5. Note the dates. A refusal under the old national framework, or under a local plan that has since been replaced, may have been decided on rules that no longer apply.

Read the reasons, not just the outcome. A refusal because of highway safety on a narrow lane says something quite different from a refusal because the land is outside the settlement boundary and the council had enough housing land. The first may be curable with a better access; the second may change if the council's housing position changes. Look too at what the council asked for on schemes it approved nearby: the affordable housing share, the drainage, the hedgerows it wanted kept.

The history shows how the council has decided before, not how it would decide your land today, because national policy, the plan and the housing figures all move. Refusals upheld at appeal, for reasons that apply equally to your land, are the clearest warning a home check can give.

Start with the boundary. Your title plan from HM Land Registry shows where your land ends. The question is whether it reaches a road that the public can use and that the council maintains, or whether there is a verge, a ditch or a strip owned by someone else in between.

The council that acts as highway authority, the county council in a two-tier area, keeps that record. Section 36 of the Highways Act 1980 requires it to keep a list of the streets within their area which are highways maintainable at the public expense, and that list may be inspected by any person free of charge at all reasonable hours. Many highway authorities also publish an online map of adopted roads, and will answer a question about where the highway boundary runs, sometimes for a fee.

• A field gate onto an adopted road is the best starting point, though a farm gateway is rarely wide enough or placed well enough for an estate road as it stands.
• A private track or lane may give you a right to pass for farming, which is not the same as a right to serve new homes.
• A strip between your land and the road owned by someone else can control whether development happens at all, and that is the subject of our guide to access and ransom strips.
• Footpaths and bridleways crossing the land are public rights of way. They can usually be kept within a layout, but they do not provide vehicle access.

What the records do not tell you is whether a safe junction can be designed. That depends on the speed of traffic, how far a driver can see in each direction from the new junction and the width of the road. Those are matters for a highways engineer and, in the end, the highway authority.

Policy S5 of the National Planning Policy Framework lists the kinds of development that should be approved outside settlements. One is housing on land well related to an existing settlement and served by infrastructure, where there is evidenced unmet need for homes. The framework says how that need is shown. Where the council scores below 75% in the most recent Housing Delivery Test, which compares the homes actually built with the homes needed, need is treated as evidenced. Where the council cannot show a five-year supply of deliverable housing sites, that shortfall is evidence of unmet need to be weighed, not an automatic finding.

The framework's other routes outside settlements do not depend on the housing figures. They include limited infilling, exception sites for affordable homes, the reuse or replacement of certain buildings and the redevelopment of previously developed land. A farmyard, a redundant barn or an old commercial yard may have a route that a bare field does not.

You can find the latest Housing Delivery Test result for every council we cover on our area pages, together with the council's five-year supply statement where it publishes one. The results change each year and a supply statement is usually updated annually, so a council can move from one row of the table to another. Our guide to the August 2026 NPPF explains the wider changes. Whatever the figures, we welcome land in every council: where a council is meeting its targets, the local plan is the usual route, and a well placed field is still worth looking at.

• I know which council decides, and I have found its planning policy pages and its planning application search.
• I have found my land on the policies map and noted every line, colour and policy number that touches it.
• I know whether my land is inside a settlement, straddles its edge, sits next to it or is away from it.
• I know whether my land is in the Green Belt.
• I have checked the flood map for planning across the whole field and the route to the road.
• I have checked MAGIC, Search the List and the local land charges search for designations on or near my land.
• I have searched the planning history on my land and within a mile or so, and read the reasons for the decisions that matter.
• I have looked for my land in the council's latest land availability assessment.
• I know whether my land meets an adopted road directly, or crosses a track or someone else's strip.
• I know the council's latest Housing Delivery Test result and whether it can show a five-year supply.

A home check stops where professional judgement begins. Whether a scheme would work financially once affordable housing, roads, drainage and contributions are paid for, whether the highway authority would accept a junction, and how the council views a particular edge of a particular village: none of these is on a free map.

That is the work a free desktop review of your land covers. It is a desktop exercise using publicly available information, and we do not contact the council, your neighbours or anyone else about your land without your agreement. We come back with a plain answer on whether the land has a realistic chance of planning permission, roughly how many homes it might take and what the main hurdles would be. If we go ahead, we pay for and run all of the planning work at our own cost and risk.
