Around a third of householder planning applications in England are refused or withdrawn each year. That figure alone should make anyone thinking about buying land stop and ask what exactly they’re getting before they commit. Land without the right permission can turn a promising development into an expensive piece of ground you can’t build on. The permission status attached to a plot determines what you can do, how long you have to do it, and what the land is actually worth.

Different plots come with different consent levels, and the price tag usually reflects that. A site with outline permission sells for more than raw agricultural land, but it also comes with conditions, deadlines, and obligations that can catch out an unprepared buyer. Local planning authorities assess each application against their Local Development Plan, and what passes in one area can get rejected in the next. Here’s what you actually need to know.
The basic meaning of planning permission and why it matters when buying land
Planning permission is formal approval from your local planning authority that allows you to carry out specific development or change the use of land or buildings. It is governed primarily by the Town and Country Planning Act 1990 and the rules that sit under it. The system exists to regulate development in the public interest, balancing what you want to do with what the wider area can handle.
What I tend to notice is that buyers focus on the land itself — the size, the location, the price — and treat the permission almost as an afterthought. But the permission is what turns a field into a building plot. Without it, you own something you can’t use. With the wrong type of permission, you could end up with a consent that expires before you’re ready to build, or one that comes with conditions that cost more to satisfy than the land did.
Application fees, timelines, and the real cost of getting permission
The fee you pay when you submit an application is only the start. You also need professional drawings, a site location plan at 1:1250 scale, floor plans and elevations, and sometimes specialist reports — a heritage statement, an ecological survey, or a flood risk assessment. These costs add up long before the council gives you an answer.

| Application Type | Fee (England, 2026) | Decision Window | What It Covers |
|---|---|---|---|
| Full Householder | £258–£335 | 8 weeks | Extensions, alterations, and changes to an existing home |
| Full New Dwelling | £578 | 13 weeks | Detailed plans for a new house or building |
| Outline Permission | Varies by scale | Up to 13 weeks | Principle of development — layout, scale, and access only |
| Lawful Development Certificate | Lower than full apps | 8 weeks | Written confirmation that existing or proposed works are lawful |
One thing that catches people out is the discrepancy in fee figures between sources. The official householder application fee was £258 according to recent guidance, but some authorities list it closer to £335 as of April 2026. Fees were revised in late 2023 and are likely to be reviewed again, so the exact amount depends on when you apply and which council handles it.
Timing matters just as much. Councils have eight weeks to determine householder applications and 13 weeks for more complex cases. If your application is refused, you have the right to appeal, but that adds months. Meanwhile, if you’re buying land with an existing outline permission, the clock is already ticking — you typically have three years to submit reserved matters from the date of approval.
Costly mistakes buyers make with planning permission
Buying land with outline permission and assuming you can build anything
Outline permission says the principle of development is acceptable, but it leaves the details open. Access, appearance, landscaping, layout, and scale all need to be approved later as reserved matters. Buyers sometimes pay a premium for outline consent and discover later that their specific design doesn’t meet the conditions. That can mean going back to submit a new full application, which costs time and money.
Not checking whether Permitted Development rights actually apply to the plot
Permitted Development rights let you carry out certain works without a full application, but they are not universal. In Conservation Areas, Areas of Outstanding Natural Beauty, National Parks, and on Sites of Special Scientific Interest, those rights are often restricted or removed entirely. A property where an Article 4 Direction has been placed can lose PD rights on specific issues like front extensions or roof alterations. What I’d do before buying any land is check whether the plot sits in a designated area — it determines what you can do without a full application.
Overlooking Section 106 agreements and Community Infrastructure Levy obligations
Many planning permissions come with legal agreements attached. A Section 106 agreement might require affordable housing provision, infrastructure contributions, or habitat improvements. The Community Infrastructure Levy (CIL) is a separate charge on new development to fund local infrastructure. These liabilities transfer with the land. A buyer who doesn’t investigate them can end up owing tens of thousands of pounds before they even break ground.
The types of planning permission and what each one means for your land purchase
Outline permission — testing the water before committing to detailed designs
Outline planning permission establishes whether the principle of development is acceptable before you invest in detailed architectural plans. You submit basic information about the proposed use, the approximate scale and layout, and access arrangements. Once outline permission is granted, you have three years to submit reserved matters — the detailed design of access, appearance, landscaping, layout, and scale. After reserved matters are approved, you have two more years to start development. This route works well when you want to check viability before spending heavily on designs, but the timeline pressure is real.
Full planning permission — the most certain route but the most paperwork
Full planning permission requires detailed plans from the start: floor plans, elevations, materials specifications, and landscaping. The council assesses everything in one go. If approved, you have three years from the date of approval to begin development. This is the safest route for buyers who know exactly what they want to build and want certainty before they purchase. The trade-off is that you pay for professional drawings and surveys upfront, and if the application is refused, you’ve spent that money with nothing to show for it.
Lawful Development Certificate — your insurance policy for existing rights
A Lawful Development Certificate does not grant new permission. It confirms that proposed or existing development is lawful under the current rules. It is useful for proving that Permitted Development rights apply to a particular project, or for establishing that historic uses of the land are legal. Sellers who already have a certificate can pass it to the buyer as proof that the development history is clean. Without one, a future buyer or lender might question whether everything on the land is above board.
Permitted Development rights and when they don’t apply
Permitted Development rights are set out in the Town and Country Planning (General Permitted Development) (England) Order 2015 (and equivalent rules in Scotland, Wales, and Northern Ireland). They allow certain works without a full application — small extensions up to size limits, outbuildings under 4 metres high, some changes of use between commercial Use Classes, and agricultural buildings under 465 square metres. But these rights disappear in sensitive areas. If the plot is in a Conservation Area, AONB, National Park, or SSSI, or if the local authority has placed an Article 4 Direction, you likely need full permission for things that would otherwise be allowed.
For buyers who want to check their position on a specific plot before purchasing, consulting with a real estate solicitor can clarify what permissions are in place and what conditions apply. It is a straightforward way to avoid buying a problem you didn’t know existed.
The application process itself follows a clear sequence. Most applications in England and Wales are submitted through the Planning Portal. You submit a completed form, a site location plan at 1:1250 scale, existing and proposed floor plans, and elevation drawings. For larger or sensitive projects, you also need a design and access statement, heritage statement, or ecological survey. Your application is publicised locally — neighbours are notified, and consultees such as highways and conservation officers provide input. The council then decides within eight weeks for householder applications or 13 weeks for more complex cases.

Planning permission is only as good as the conditions attached to it
The most overlooked part of any planning consent is the small print. Conditions can require you to complete a highway access before you start building, submit a drainage strategy, or install noise mitigation measures. A Section 106 agreement might demand affordable housing contributions or habitat creation. These are not optional extras — they are legally binding obligations that you inherit with the land. Buyers who focus only on the headline “permission granted” and skip the conditions often find their budget stretched before the first brick is laid.
