Permitted Use
Residential, care, retail, industrial, logistics, office and mixed-use permissions create different revenue, cost and funding profiles. Restrictions on use or occupancy may materially affect demand and value.
The value created by consent
Why Can Planning Permission Increase Land Value?
Permission can move land from a speculative opportunity towards a defined development proposition, but the value uplift depends on the quality and deliverability of the approved scheme.
Before planning permission, a purchaser must price the risk that consent may be refused, delayed, reduced in scale or made subject to costly requirements. A lawful and implementable permission removes part of that uncertainty. It can also widen the buyer market because housebuilders, commercial developers, investors and funders can assess a defined scheme rather than an untested possibility.
The uplift is not simply the difference between agricultural value and a generic development-land rate. The buyer normally starts with the value of the completed homes, buildings or serviced plots, then allows for construction, infrastructure, professional fees, finance, planning obligations, risk and profit. The amount remaining informs what can be paid for the land. Our general UK land valuation guide explains the wider methods; this page focuses on the consented stage.
Two permissions for the same number of homes can therefore produce different land values. One may have a straightforward access, established utilities and modest abnormal costs. The other may require a new junction, extensive drainage works, ecological mitigation, ground remediation and substantial planning contributions. The headline number of dwellings is only one input.
The status of the permission also matters. A consent that remains open to legal challenge, depends on a section 106 agreement that has not been completed, or requires major pre-commencement conditions to be resolved will carry more risk than a permission capable of prompt implementation. Buyers may respond through a lower price, retentions, deferred payments or additional contractual conditions.
Planning permission should therefore be viewed as a value-defining document rather than a simple certificate that development is possible. The decision notice, approved drawings, obligations and supporting evidence need to be read together before a realistic opinion of value can be formed.
There is no reliable universal multiplier for land with planning permission. The correct question is what the approved development can generate after all realistic costs, obligations, risks and buyer requirements have been allowed for.
Read the consent, not only the decision headline
The Planning Details That Can Determine the Price
A buyer will test the permission at a much more detailed level than the description appearing on the council’s decision notice.
Approved Capacity
The number, size, tenure and mix of dwellings, or the amount and specification of commercial floorspace, directly influence gross development value. Capacity must be based on the permission rather than an optimistic gross-acre assumption.
Consent Type
Outline, full, hybrid and reserved-matters approvals provide different levels of certainty. The buyer will identify which matters remain open and what further applications or approvals are required before construction.
Planning Conditions
Pre-commencement, phasing, materials, drainage, ecology, highways and contamination conditions can affect programme and cost. A condition that appears routine may depend on substantial investigation or third-party approval.
Section 106 Obligations
Affordable housing, education, transport, open space, monitoring and other obligations can reduce residual land value. Trigger dates and indexation are as important as the headline contribution.
Community Infrastructure Levy
Where CIL applies, liability depends on the charging schedule, permitted floorspace, reliefs, exemptions and timing. The assumed amount should be verified rather than treated as a generic allowance.
Access and Infrastructure
The consent may depend on roads, junction works, utilities, drainage, retaining structures or land outside the title. Buyers will price whether those works and rights can actually be delivered.
Implementation Period
A permission with limited time remaining may require urgent condition discharge or a lawful material start. Programme pressure can reduce competition or cause buyers to insist on completion protections.
Different forms of permission
Is Full Planning Permission Always Worth More Than Outline Permission?
Greater detail can reduce uncertainty, but a more detailed consent is not automatically more valuable if the approved scheme is inflexible, expensive or poorly aligned with the purchaser’s product.
Outline Permission and Reserved Matters
Outline permission normally establishes the principle of development and may approve access while reserving appearance, landscaping, layout or scale. It can be attractive where a purchaser wants to adapt the detailed design to its house types, construction method and market strategy.
The outline parameters, illustrative masterplan, environmental limits and section 106 agreement still matter. A maximum figure stated in the description does not prove that every unit can be delivered at reserved-matters stage. The purchaser will test whether the approved access, drainage, green infrastructure and design parameters support the assumed capacity.
Reserved matters, condition discharge and technical approvals require time and expenditure. The land value may therefore reflect the remaining risk and the buyer’s cost of converting the outline consent into a construction-ready scheme.
Full and Detailed Permission
Full permission can provide a defined layout, house mix, access, drainage strategy and landscaping scheme. This may increase confidence where the design has been carefully tested and is compatible with the intended buyer market.
Detail can also reduce flexibility. A purchaser may need a variation, non-material amendment or fresh application if the approved house types, density, road layout or materials do not suit its requirements. The cost and planning risk of those changes can affect its offer.
The practical comparison is therefore not outline versus full in isolation. It is the residual value, programme and risk of the particular permitted scheme after the next approvals, conditions and obligations have been identified.
How purchasers calculate their offer
The Residual Appraisal Behind Consented Land Value
Development land is commonly assessed by considering the value of the completed scheme and deducting the expenditure and return required to deliver it.
The starting point is normally the expected sales value or investment value of the completed development. For housing, this may involve analysing unit type, size, tenure, specification, release rate and local new-build evidence. For commercial property, rental value, yield, letting assumptions, incentives and purchaser demand may also be relevant.
The appraisal then allows for construction and external works. These are not confined to the buildings. Roads, drainage, utilities, landscaping, retaining structures, demolition, remediation, habitat works, site preparation and off-site improvements can represent a substantial part of total expenditure.
Professional fees, planning costs, warranties, surveys, sales and marketing costs, finance, contingencies and developer’s profit are also included. Section 106 obligations, affordable housing and CIL need to reflect the actual permission and legal documents rather than a broad national assumption.
The residual amount after those items have been deducted informs the land value. Timing matters because costs and receipts arise at different stages. A phased scheme may require a cash-flow appraisal so that finance and the delay before later receipts are properly reflected.
Residual appraisals are sensitive. A modest change in sales values, build costs, interest, programme or affordable housing can produce a much larger change in the amount left for land. A single spreadsheet result should therefore be tested against comparable transactions, current bids and alternative development scenarios.
The landowner should distinguish an independent opinion of market value from a particular buyer’s internal appraisal. One purchaser may have a lower build cost, a stronger sales outlet, existing infrastructure or strategic reasons for acquiring the site. Competitive marketing can reveal value that is not apparent from a single confidential offer.
A headline offer is only meaningful when the landowner understands the permitted scheme, assumptions, deductions, payment timing and conditions attached to it. The highest stated figure may not produce the highest certain net receipt.

The deductions beneath the headline value
Development Costs That Can Reduce the Land Receipt
The approved development may generate substantial revenue, but the purchaser must fund every stage required to turn the permission into completed and saleable property.
Building and External Works
Construction, roads, drainage, landscaping, demolition, site compounds and abnormal preliminaries are assessed against the approved layout, specification, ground conditions and programme.
Affordable Housing
The percentage, tenure, transfer values, design and timing of affordable housing affect revenue and cash flow. Review mechanisms or late-stage provisions can create further uncertainty.
Planning Contributions
Education, highways, public transport, open space, healthcare and other section 106 obligations may be payable at different triggers and can be indexed between agreement and payment.
Highways and Access
Junction improvements, visibility works, road widening, signals, active-travel links and section 278 works can be material costs, particularly where third-party land or utility diversions are involved.
Flooding and Drainage
Attenuation, pumping, outfalls, watercourse works, easements and adoption requirements can reduce net developable area and increase both capital and long-term management costs.
Ecology and Biodiversity
Habitat retention, protected-species mitigation, Biodiversity Net Gain and long-term habitat management can require land, specialist work and financial provision.
Utilities and Capacity
Electricity reinforcement, substations, water, foul drainage, gas, telecommunications and diversions should be checked against actual provider information rather than assumed availability.
Ground and Site Abnormals
Contamination, unstable ground, mining, archaeology, retaining structures, difficult levels and major earthworks can materially alter the purchaser’s appraisal.
Conditions can change certainty and programme
Why the Decision Notice Must Be Read With the Approved Documents
A permission can appear straightforward until the conditions, legal agreement, parameter plans and technical reports are examined together.
Pre-commencement conditions may prevent lawful development from starting until details have been submitted and approved. These can cover drainage, contamination, archaeology, ecology, construction management, highways, levels and materials. The time and evidence needed to discharge them should be reflected in the sale programme.
Some conditions restrict occupation rather than commencement. A scheme may be buildable but unable to complete or occupy more than a stated number of units until a road, school contribution, drainage connection or other infrastructure item has been delivered. This can affect phasing, finance and sales receipts.
A Grampian-style condition may depend on works outside the site or action by a third party. The buyer will want evidence that the necessary land, agreement, licence and funding can be secured. A consent that relies on an uncertain off-site solution may be valued more cautiously.
The section 106 agreement should be checked for definitions, triggers, indexation, review mechanisms, mortgagee protections, nomination arrangements and obligations affecting successors. The decision notice alone will not reveal the full commercial burden.
Approved plans and reports may contain commitments that are not repeated word for word in the conditions. Landscape buffers, ecological areas, drainage basins, access parameters and retained buildings can limit the land available for saleable development. The realistic capacity should come from the entire consent package.
Capacity must be deliverable
Gross Site Area, Net Developable Area and Approved Density
Per-acre comparisons can mislead where large parts of the title are required for infrastructure, landscape, drainage, habitat or open space.
Establish the Land That Generates Value
The gross title area may include woodland, watercourses, steep slopes, access corridors, retained homes, utilities, ecological buffers and land outside the permission boundary. These areas can support the scheme but do not necessarily carry the same value as a serviced residential or commercial parcel.
The permission should be measured against the approved plans and a reliable survey. A topographical survey can identify levels, features and boundaries that influence earthworks, drainage, roads and developable platforms.
Check Capacity Against the Consent
An outline description may refer to “up to” a maximum number of dwellings. That figure is a ceiling, not a guarantee. Reserved matters and condition discharge may reduce capacity once detailed roads, drainage, landscaping and house types are designed.
A full permission can provide a firmer schedule, but the purchaser may still test whether every plot is practical, marketable and capable of being built within the approved levels and infrastructure strategy. Apparent planning capacity and commercial delivery capacity are not always identical.
Land value should therefore be linked to a realistic permitted development scenario. Any alternative or enhanced scheme should be identified as a separate planning assumption rather than blended into the value of the current consent.
Compare the whole bid
Why Different Buyers May Offer Different Prices for the Same Permission
A planning permission provides a common starting point, but purchasers have different costs, products, funding, risk tolerances and strategic objectives.
A national housebuilder may value the site according to its standard house types, regional sales outlet and return targets. A local developer may identify a niche product or deliver a smaller scheme efficiently. A registered provider, investor or neighbouring owner may value particular aspects differently. Competition can therefore produce a range of credible bids.
The structure of each bid matters. One offer may be unconditional but lower. Another may be subject to ground investigation, condition discharge, a satisfactory variation, finance approval or board approval. A higher figure with broad withdrawal rights may provide less certainty than a slightly lower offer with limited conditions.
Payment timing can change the true commercial result. Deferred consideration, staged completion, retentions and payments linked to reserved matters or unit sales expose the seller to future performance and counterparty risk. The contract needs clear dates, interest provisions, security and remedies.
Deductions should be identified before exclusivity. A purchaser may quote a gross land value while reserving the right to deduct planning costs, abnormal works, section 106 changes or other expenditure later. The seller should understand whether the stated price is fixed, formula-based or subject to reappraisal.
A structured marketing process allows offers to be compared on a consistent basis. The Selling Land for Development Guide explains preparation, buyer information, bid comparison and heads of terms in more detail.
Choosing the sale point
Should the Land Be Sold Immediately After Permission?
The best sale point depends on how much uncertainty remains, what further value may be created and whether the landowner is willing to fund or manage the next stage.
Selling after outline permission can transfer reserved-matters, condition and construction risk to the purchaser. This may suit a landowner who wants a prompt receipt and does not wish to fund additional professional work. The offer will usually reflect the approvals and investigations still required.
Progressing reserved matters or discharging key conditions may increase certainty and widen the market, particularly where access, drainage, contamination or capacity is unresolved. The potential uplift should be compared with the cost, delay and risk of undertaking that work.
The expiry date requires active management. A material start may preserve the permission, but the legal and technical requirements for lawful implementation must be confirmed. A token operation undertaken without satisfying relevant conditions may not achieve the intended result.

Contract structure after consent
Sale and Agreement Routes for Land With Planning Permission
A consented site may be sold unconditionally, conditionally or through a formula-based arrangement depending on the remaining planning, technical and commercial issues.
A Defined Sale Price
An unconditional sale can provide certainty where the purchaser has completed due diligence and accepts the existing permission. The contract should define the property, included documents, completion date, title position and any retained rights or obligations.
A conditional contract may be used where completion depends on a variation, reserved matters, ground investigation, access agreement or another specified outcome. The condition and acceptable result need objective drafting.
Competitive marketing remains important even where permission exists. A private approach from the applicant, promoter or neighbouring developer should be assessed against the wider market unless there is a clear reason not to do so.
Formula, Deferred or Further-Uplift Terms
Deferred payments can bridge a purchaser’s cash-flow requirements, but they expose the seller to credit and enforcement risk. Security, interest, release mechanics and the effect of onward disposals should be resolved in the heads of terms.
Where the purchaser expects to improve the permission, the parties may consider an overage or additional payment linked to increased capacity, a more valuable use or future sales. The base consent, deductions, trigger and valuation date must be unambiguous.
An option or promotion agreement is more commonly considered before value has been fully created, although it may remain relevant where a fresh or substantially improved consent is required. Independent legal and valuation advice should be obtained before any agreement is signed.
Our initial assessment
How Value My Land Reviews a Consented Development Site
The review brings the permission, site characteristics and likely buyer market together before a landowner commits to a sale strategy.
Confirm the Permission
We identify the planning reference, consent type, approved description, time limits, decision notice, plans and status of any section 106 agreement or reserved matters.
Review Capacity and Constraints
We consider the permitted quantum, access, drainage, landscape, ecology, ground, utilities, phasing and land required to support the scheme.
Identify Commercial Deductions
We note the apparent obligations, infrastructure and abnormal issues likely to influence a purchaser’s residual appraisal and due diligence.
Consider the Market Route
We consider whether immediate marketing, further approvals, a conditional sale or another structured route may better match the landowner’s objectives.
Keep assumptions realistic
Common Reasons Consented Land Is Overvalued
Overvaluation usually arises when the planning headline is separated from the approved scheme, delivery costs or terms on which a buyer can actually complete.
Using a generic price per gross acre is a common error. It ignores the permitted use, net developable area, density, local sales values and infrastructure burden. Comparable evidence needs adjustment for differences between sites and transactions.
Treating the maximum outline capacity as guaranteed can also overstate value. Detailed design, drainage, access, habitat, open space and house-type requirements may reduce the number or mix of saleable units.
Ignoring affordable housing, section 106, CIL and indexation produces an appraisal that a purchaser cannot rely upon. These obligations should be taken from the current documents and tested against the proposed completion and development dates.
Assuming every condition is inexpensive can conceal programme risk. Intrusive investigation, off-site highway approval, drainage consent or protected-species work may delay implementation and alter cost. Material conditions should be investigated rather than grouped under a nominal allowance.
Planning permission can create substantial value, but the landowner should value the consent that exists, identify any additional-consent assumptions and compare the probable net proceeds under realistic sale terms.
August 2026 National Policy
How the August 2026 NPPF Should Be Used When Valuing Land With Permission
Once permission exists, the central valuation question is what the approved scheme can actually deliver. National policy remains relevant to viability, conditions and obligations, but the decision notice, approved plans and legal agreement define the consent being purchased.
Value the Permission Actually Granted
Check the approved use, unit numbers, floorspace, tenure, access, phasing and reserved matters. A headline description of the application may differ from the scheme secured by the decision and accompanying documents.
Read Conditions and Obligations Together
Pre-commencement requirements, section 106 contributions, affordable housing, highway works, CIL and infrastructure triggers affect cost and programme. They should be reflected in the appraisal rather than deducted informally after a headline land figure is discussed.
Test Whether the Consent Is Implementable
Confirm the permission period, reserved-matters deadlines, land control, access rights, discharge requirements and any condition that depends on third-party agreement. A permission that cannot be lawfully or practically implemented carries a different value.
Appraise the Approved Net Development
Use realistic sales values, build costs, finance, professional fees, abnormal works and developer return for the permitted scheme. DM5 means the purchase price itself should not be used as a reason to assume reduced policy compliance.
Planning permission can materially reduce risk, but it does not guarantee a standard price per acre. The value is the residual supported by the consented scheme after its conditions, obligations, delivery risks and market assumptions have been properly modelled.

Read guideFrequently Asked Questions About Land Value With Planning Permission
Does outline planning permission increase land value?
Outline permission can increase value because it establishes the principle of development and reduces an important part of planning risk. The amount of uplift depends on the approved use, maximum capacity, access, parameter plans, section 106 obligations and the matters still reserved. A purchaser will also allow for the cost and risk of reserved matters, condition discharge and any technical approvals. Outline permission should therefore be valued as the particular consent granted, not as a guaranteed final number of homes.
Is full planning permission always worth more than outline permission?
No. Full permission may provide greater design and delivery certainty, but it can also approve a scheme that is expensive, inflexible or unsuitable for the strongest buyer market. Outline permission may allow a purchaser to use its own house types and detailed layout, although it carries additional approval risk. The relevant comparison is the residual value and programme of each actual scheme after obligations, costs and necessary changes have been considered.
How do developers calculate what they can pay for consented land?
A developer normally assesses the expected value of the completed development and deducts construction, infrastructure, professional fees, finance, planning obligations, marketing, contingency and the required return for risk. The residual amount helps inform the land offer. Purchasers will also compare recent transactions and competing opportunities. Small changes in sales values, build costs or programme can have a disproportionate effect on the residual result, so a single appraisal should not be treated as an automatic market price.
Do section 106 obligations reduce land value?
They can. Affordable housing, education, transport, open space and other obligations are costs or revenue restrictions associated with the permission. Their effect depends on the amount, trigger, indexation, tenure and delivery mechanism. Government viability guidance expects policy costs to be reflected in land pricing. A landowner should obtain the completed agreement and understand its commercial effect before comparing bids or assuming a value.
Does CIL apply to every consented development?
No. CIL depends on whether the authority has an adopted charging schedule, the development type and floorspace, and whether any exemption or relief applies and is properly claimed. Liability and payment timing can be affected by commencement and phasing. The purchaser should verify the position with the planning documents and charging authority. A generic allowance may be inaccurate and could distort the land appraisal.
Can planning conditions reduce the price offered?
Yes. Conditions can require surveys, approvals, works or third-party arrangements before development starts or occupation occurs. A buyer may reduce its price or make the sale conditional if a material condition creates cost, delay or uncertainty. Routine conditions are less likely to affect value substantially, but drainage, access, contamination, ecology, archaeology and off-site infrastructure conditions should be reviewed carefully before marketing.
Is land valued per acre after planning permission?
Per-acre evidence may be used as a broad market comparison, but it should not replace a site-specific assessment. Gross acreage can include roads, drainage, open space, habitats and other supporting land. The permitted unit mix, local sales values, obligations and abnormal costs vary between sites. A reliable comparison adjusts for those differences and is normally cross-checked against the residual value of the approved scheme.
Should I discharge conditions before selling?
It depends on which conditions remain and whether resolving them is likely to create more value than it costs. Discharging a key access, drainage or contamination condition may widen the buyer market and reduce price deductions. Spending money on routine details that a purchaser would prefer to control may add little. The decision should compare likely uplift, programme, professional costs and the risk that the approval sought is delayed or changes the scheme.
What documents will a buyer need?
A buyer will commonly request the decision notice, approved plans, section 106 agreement, CIL information, application reports, surveys, title documents, utility information and correspondence concerning conditions. Reserved-matters and condition-discharge submissions should also be included. A coherent data room allows purchasers to price the same information and reduces the scope for late renegotiation. The precise requirements will depend on the site and transaction.
