Below is our ultimate guide to the value of land with planning permission, which answers everything you will need to know. We also explain how Intelligent Land can help to unlock hidden millions in land value by combining proprietary AI with three decades of planning expertise.
Most landowners and developers suspect there’s more value in their site than the headline numbers suggest.
They’re usually right – to find out more, read about the Land Value Accelerator™ (LVA Method™).
Land value with planning permission in the UK
When people search online for land value with planning permission, they’re often after a simple multiple they can apply to an acre or a plot. The truth is more nuanced, and more profitable when handled correctly. Planning permission is not a binary badge; it’s a bundle of rights, obligations and risks that interact with the economics of development.
The land value with full planning permission with cleanly drafted, dischargeable conditions and a sensible Section 106 is worth materially more than outline consent with ambiguous access or unresolved highways triggers. Likewise, reserved matters approvals that bake in a restrictive layout can suppress value even when the headline permission looks strong.
Land value with planning permission usually follows the residual land value (RLV) approach: estimate the gross development value (GDV), deduct all costs (including abnormals, infrastructure, professional fees, finance, contingency, planning obligations and biodiversity commitments), and what remains is the land value (which we can help you to maximise further).
That sounds linear until you realise each assumption can move the outcome dramatically. A two‑point change in yield on a build‑to‑rent scheme, or a modest change in density on a suburban housing site, can swing seven figures. So, the practical task isn’t to “apply a number”, but to interrogate the permission, the technical pack and the market to find an optimal combination of mix, layout, phasing and obligations that increases the RLV without increasing risk.
Where Intelligent Land differs is the speed and depth of that interrogation. Our LVA Method™ runs thousands of scenarios in minutes, revealing combinations that conventional models rarely explore. Think of it as an “explore engine”: we don’t guess one or two answers on land value; we map the fat‑tailed upside and show you the shortest credible route to achieve it.
That’s why some clients can see a £1m+ uplift identified within 24 hours – because the increased value of the land with planning permission was there all along; it just needed to be reframed and tested, fast and precisely.

The value of land with planning permission
The value of land with planning permission rests on three pillars:
- the quality of the consent,
- the credibility of delivery,
- and the market you’re selling into.
Quality starts with the exact wording of the permission and its conditions
Are triggers staged or front‑loaded? Is access provisional or fixed? Do ecology or drainage requirements lock you into a costly solution, or can they be met more efficiently with a revised design and management plan? Small edits to obligations or phasing can release millions when they pull cash‑out earlier or reduce peak debt.
Credibility of delivery is about more than compliance
It’s a story you can substantiate: the surveys are current, statutory consultees have a clear path to discharge conditions, the utilities and highways strategies are costed and agreed in principle, the biodiversity solution is practical, and the design supports absorption rates the finance model assumes.
Buyers pay a premium for certainty because certainty cheapens capital
If two sites have similar GDV but one removes 80% of the “unknowns” in week one, it will command a higher price and building land value with planning permission, but faster.
Finally, the market context matters
Identical permissions behave differently in different places and cycles. A logistics unit near a strategic road network has a completely different value trajectory to a town‑centre resi‑over‑retail conversion.
The answer isn’t to rely on averages; it’s to model the specific demand and exit to your site, then use planning and design levers to align with that demand.
Our clients are frequently surprised by how much value sits in re‑sequencing infrastructure, re‑mixing tenure, or adjusting unit sizes to match local absorption.
These are planning‑led moves with financial consequences.

How to value land with planning permission
With or without our help, here’s a checklist to help you value your land with planning permission.
- Decision notice: list conditions, triggers, time limits.
- Red‑line & drawings: confirm what’s actually permitted.
- Technical pack: ground, utilities, highways, drainage, ecology, heritage.
- Obligations: Section 106/CIL timing and cashflow impacts.
- Delivery story: who will buy/occupy and when.
Start by auditing the permission as if you were a sceptical buyer. Read the decision notice slowly. Identify every condition, its trigger, and whether it is genuinely dischargeable with the information available. Note time limits, pre‑commencement hurdles, and any dependencies between conditions.
A permission that looks tidy on the surface can hide a pre‑commencement ecology or highways requirement that freezes value until expensively resolved. Next, check the associated documents: plans, sections, Design & Access Statement, Transport Assessment, Flood Risk and Drainage strategies, ecology reports, heritage statements.
You’re looking for alignment: does the permission allow a buildable, saleable solution without redesigning the site from scratch?
Move to the technical pack. Ground conditions, utilities capacity and diversions, highways and access works, drainage outfalls, contamination and remediation, noise and air quality, ecology mitigation and biodiversity plans – each of these can add six or seven figures. Many sites carry avoidable cost because assumptions are legacy guesses. Updating surveys and re‑testing a network or an outfall can cut abnormals, remove contingencies, or unlock a simpler solution.
In parallel, review your Section 106 obligations and any Community Infrastructure Levy position.
Sometimes phasing or partial occupation triggers can be reshaped to reduce the early cash burden without diminishing outcomes for the authority.
With the permission and technical baseline understood, build your residual model. Anchor it to realistic GDV supported by local evidence, adjust for product and absorption, and then work through costs with a forensic lens. Be explicit about prelims, overheads, profit, fees, finance and contingencies.
Stress‑test the model: what happens if you add ten homes by refining layout, or change the tenure mix to bring in an institutional purchaser, or alter phasing so infrastructure draws are spread? This is where AI is powerful.
The LVA Method™ runs scores of credible variants automatically and identifies which combination of density, mix, layout, phasing and obligations yields the highest land value without increasing risk. It also highlights which conditions or consents most constrain value, so you can prioritise variations and negotiations. The outcome is not a theoretical number; it’s a route map to a higher price that a buyer, funder or committee can believe in.
How much value does planning permission add to land in the UK?
There isn’t a single percentage that fits all sites, but there are patterns worth understanding.
Four forces that shape uplift:
- Permission type & quality: full vs outline, dischargeable conditions.
- Obligations profile: S106/CIL phasing, front‑loaded triggers.
- Abnormal/infrastructure costs: utilities, ground, drainage, highways.
- Market timing & product fit: demand for the permitted use and exit route. Planning permission typically converts “hope” into “deliverable”, and that shift reduces risk premia throughout the stack. Developers sharpen their pencils because sales, leasing and funding assumptions move from hypothetical to bankable. That reduction in perceived uncertainty is itself valuable. In markets with strong demand for the permitted use, you can see dramatic uplifts between existing‑use value and consented land value. In softer markets or with restrictive consents, the uplift can be modest.
What influences the size of the uplift?
First, the type and quality of the planning permission permission. Full planning with well‑sequenced, dischargeable conditions tends to outperform outline consents dependent on complex reserved matters.
Second, the obligations attached to the scheme. A Section 106 that front‑loads infrastructure or requires early delivery of items that don’t directly support sales can suppress land value.
Third, abnormal and infrastructure costs. If utilities diversions, ground conditions or drainage are poorly understood, buyers will price them pessimistically. Fourth, the market timing for your specific product. A suburban family housing scheme is driven by different absorption dynamics to a city‑centre build‑to‑rent block or an industrial estate on the edge of a motorway junction.
Crucially, not all planning permissions add the same value even on comparable sites. Tiny operational details – moving a site access to avoid a costly junction, re‑arranging plots to increase net developable area, adjusting unit sizes to match Help to Buy’s historical thresholds (or their financing equivalents), altering tenure mix to attract an institutional forward‑fund – can swing outcomes materially. It’s common to find an apparently “tight” appraisal that becomes viable when a handful of these levers are pulled in concert.
Our experience with LVA is that the big wins are usually counter‑intuitive: value is often hiding in conditions, obligations and phasing rather than in the obvious headline numbers. The job is to expose and sequence those wins fast enough that the market recognises and pays for them.

How to value land without planning permission
Without permission you’re valuing probability and pathway as much as product. It is still possible to value land without planning permission when you build a probability‑weighted plan in five moves:
- Policy fit: local plan, supply position, recent appeals.
- Scenarios: refusal/EUV, limited consent, optimal consent.
- Weights: credible probabilities tied to evidence.
- Next steps: targeted surveys, pre‑app, consultee strategy.
Deal structure:
Begin with policy fit: how does the site align with the local plan, neighbourhood plan, and any strategic allocations? Are there recent appeal decisions nearby that indicate the planning direction of travel? Is there housing land supply pressure or an evidenced need for employment or logistics space? These factors shape the likelihood of success and, therefore, the price you should pay today.
Construct a probability‑weighted residual. Model at least three planning outcomes – for instance, refusal (existing‑use value), a limited permission, and an optimal permission – and assign credible probabilities to each. Weight the RLVs accordingly to arrive at a current value. This approach forces discipline. If the only way your bid stacks up is with a low‑probability, high‑density outcome, you’re speculating. But if multiple plausible outcomes produce acceptable returns, you have a robust position.
Next, consider route and risk. What is the pre‑application strategy? Which surveys will move the conversation forward fastest: transport scoping, ecology baseline, drainage capacity checks, utilities capacity letters, heritage screening? How will you structure engagement with statutory consultees and local stakeholders, so the scheme’s benefits are legible? Investors and promoters pay more for land when the next steps are clear, achievable and sequenced. Option and promotion agreements can be designed to reflect this: long‑stop dates, overage mechanisms, and incentive structures should align everyone to a timely, value‑maximising permission.
Finally, decide how to de‑risk early. Sometimes the best move is to secure a smaller, strategic first phase that unlocks access or services, proving deliverability and establishing value for later phases. Sometimes the right call is an application that deliberately leaves room to adjust mix and density once market evidence arrives. AI helps here.
The LVA Method™ tests many permutations quickly and shows which pathway delivers the highest expected value after weighting for probability, cost and time. That’s a very different conversation with sellers, funders and committees because it reframes you from “hoping for permission” to “engineering a permission the market wants and will fund”.
How much does planning permission add to land value?
The short answer is: enough to change lives when it’s optimised, and frustratingly little when it isn’t.
Levers that typically move value fastest:
- Access & layout tweaks that add plots or remove costly junctions.
- Tenure/mix adjustments that enable forward‑funding and earlier cash‑in.
- BNG/conditions re‑sequencing that lowers early cash burden. The longer answer requires recognising how sensitive land value is to a small set of inputs. Consider a modest suburban housing site. If you refine the layout to add ten saleable plots without increasing infrastructure, the extra GDV may dwarf the marginal build cost, driving a disproportionate increase in residual land value. If you shift tenure to enable an early forward‑funding deal, you may reduce finance costs and bring cashflows forward, which compounds value. Conversely, if a condition forces an expensive off‑site highway scheme prior to first occupation, it can swallow the margin that otherwise accrues to the land. Read more about BNG for developers.
Market context amplifies or dampens these effects. In a rising market with strong buyer demand, absorption rates and sales values support earlier cash‑out and higher GDV; that uplifts land value given a fixed return requirement. In a flat or falling market, sensitivity to build cost inflation and yield movement becomes the dominant story, and a permission that lacks flexibility will underperform. That’s why one site with “permission” sells poorly while another with permission sells at a premium: the better‑performing site has quietly engineered its conditions, layout and obligations to align with the market it’s selling into.
This is where our contrarian stance helps. Rather than fixate on averages – “permission adds X%” – we show clients how to change the question: which specific, implementable moves on this site will change the cashflows most for the least effort and risk?
The LVA Method™ runs through thousands of combinations and flags the ones that consistently dominate: a different access alignment that reduces highways cost; a biodiversity solution that is cheaper to deliver and easier to maintain; a re‑mix of house types or unit sizes that improves sales velocity; a phased infrastructure sequence that lowers peak debt. Each move nudges residual land value upward. Together, they reprice the land.
Valuing without permission starts with existing‑use value (EUV) and alternative‑use value (AUV). EUV is the worth of the site in its current lawful use today. AUV looks at the best alternative use achievable without a formal permission change (or with a straightforward prior approval), adjusting for costs. Everything above that is “hope value”: the premium a buyer will pay because they believe a higher‑value permission is achievable within a reasonable timeframe and risk.
The hope value isn’t fantasy when it’s grounded in a credible story. If local policy points towards growth, if land supply is constrained, if there are strong comparables and supportive appeal decisions, buyers will pay more today because the probability‑weighted future is better than the present.
Conversely, if policy is hostile, infrastructure is distant, or environmental constraints are severe, hope value collapses to zero. The challenge is to quantify this, not hand‑wave it. That’s why we advocate building a probability‑weighted appraisal with explicit assumptions about timing, costs and outcomes.
You must also price constraints honestly. Access onto the strategic road network, utilities diversions, drainage rights, flood mitigation, contamination, heritage and landscape impacts – each can be a value anchor. Yet many sites write them off too early.
Adjusting the red line to capture a better access, securing options over service corridors, or sequencing a first phase that proves viability can shift probability and uplift current value.
The psychology matters too.
A buyer who believes you’ve done the hard thinking, locked down key uncertainties, and built a clean pathway will offer more because they face fewer unknowns. That perceived certainty is real value.
Our LVA Method™ packages this into a single, clear output. We test multiple planning routes, mix and density variants, and infrastructure sequences to show the range of credible outcomes. We then identify the fastest, most achievable path to a higher valuation. For landowners, this is often the difference between accepting a speculative offer and negotiating from a position of strength. For promoters and developers, it’s the difference between a marginal deal and a bankable one.

What is the value of 1 acre of land with planning permission?
Per‑acre numbers are tempting, but they mislead when lifted out of context.
What actually drives per‑acre figures:
- Net developable area vs gross site area.
- Product/permission: density, mix, and absorption.
- Cost anchors: access, utilities, drainage, off‑site works.
- Cashflow shape: phasing and triggers that affect finance. One acre of net developable suburban land with permission for family housing does not equal one acre of gross, irregular, constraint‑heavy land on the edge of town. Value adheres to net developable area, not the headline site size, and it tracks the permitted product, infrastructure, obligations and market. Still, you can make sense of “an acre with permission” by reading it through a residual lens and then expressing the outcome per acre once you’ve normalised for what that acre actually delivers.
The practical approach is to start with the permission and the plan. How many saleable plots or square metres does the acre carry once you account for roads, drainage, open space and ecology? What’s the density and mix, and how does it relate to local demand? Then work through costs, paying attention to items that scale poorly with small sites: access works, utilities connections, drainage outfalls and attenuation, and any off‑site obligations. Two sites with similar GDV per acre can end up miles apart because one shoulders an early highways trigger while the other defers it to a later phase. Finance magnifies the difference: bringing cash‑in earlier through forward‑funding or tenure adjustments can change the residual by a surprising amount.
To make this concrete, imagine two one‑acre scenarios. Site A is a suburban infill with permission for houses, uncomplicated ground, existing connections, and light‑touch obligations. Site B is similar on paper but requires a junction upgrade before first occupation and carries a biodiversity requirement that demands off‑site units. In our modelling, Site A’s residual per acre often exceeds Site B’s by a multiple, not a margin. It’s not because the market pays more for A as an abstract acre; it’s because the permission, obligations and delivery strategy create a simpler, cheaper, faster path to sales. The lesson is clear: if you want a strong per‑acre number, optimise the permission and the delivery story, not just the brochure.
Theoretical case study: hidden millions found
We cannot share real case studies online, instead you can contact us to find out more, so here’s a theoretical example where land value is increased with planning permission.
A regional housebuilder brought us a site with an outline consent and a reputation for being “tight”. The appraisal showed little room for land value once infrastructure and obligations were costed. We ran the LVA Method™ and found three compounding moves.
- First, we shifted the access alignment to avoid a costly junction configuration, reducing highways spend and shortening the programme.
- Second, we re‑balanced the unit mix to increase absorption without diluting GDV, supported by local evidence.
- Third, we repackaged the biodiversity strategy with a management plan that delivered better outcomes on‑site and reduced off‑site costs.
Together, these changes transformed the residual. Within 24 hours we had a scenario pack with an uplift north of seven figures, and a pathway to secure the necessary variations. The site went from marginal to investable not through wishful thinking but through precise, practical alterations that a buyer and the authority could support.
The Land Value Accelerator™ (LVA Method™)
Our method is straightforward and rigorous. We begin by reviewing your planning permissions – status, conditions, triggers, time limits and reserved matters – so we know exactly what the consent allows and what constrains it.
We then undertake targeted research across the technical, legal, BNG, ESG and planning domains to build a reliable baseline.
Finally, we run AI‑driven scenario testing at scale. Instead of exploring one or two options, we generate thousands of credible combinations of layout, density, mix, obligations and phasing, and rank them by residual land value, risk and deliverability.
The output is a clear recommendation backed by evidence and a plan to secure it.
Clients choose Intelligent Land because we move quickly and we don’t stop at advice. We put the black‑box insights to work with white‑glove delivery – coordinating the specialists, shaping the applications, and helping you negotiate the variations and obligations that release value.
In many cases we identify £1m+ of uplift within 24 hours because speed is a form of value in itself: it changes decisions, funding and momentum.
Ready to unlock hidden millions?
Most sites hide value in plain sight: a condition that can be re‑sequenced, a layout that yields a few more saleable plots, a biodiversity plan that costs less and does more, a tenure tweak that improves cash‑in, a phasing strategy that lowers peak debt. Intelligent Land exists to find and deliver those wins quickly. If you want certainty, speed and a higher number on completion, let’s talk.
