Land Appraisal
Understand the real value of your land
At Bellco, we offer free, no obligation land appraisals to help landowners, homeowners and agents understand what their land is truly worth.
We look at every site as a developer and lender would, carefully, transparently and with data to back every decision.
Many people are told their land is worth more than it really is. But with rising build costs, tougher planning rules and higher professional fees, the reality can be very different.
Our goal is to educate you on how land is valued, what factors affect it and how we calculate realistic figures that you can trust.
With our local knowledge, we understand the true cost of building across Sussex and Kent. Our figures are based on real construction data, not guesswork, giving you the clarity you need before making big decisions.
How Land Is Really Valued
Land valuation isn’t guesswork – it’s a formula.
At its simplest, we start with the total Gross Development Value (GDV), what the completed homes will sell for, and work backwards, deducting all the real world costs involved in delivering the scheme.
View a typical high level calculation below:
- Gross Development Value (GDV)
- 20-25%
Developer Profit
- 7-10%
Planning and Professional Fees
- £2,300/m²
Build Cost + 10% Contingency
- 12%
of Build Cost for Finance Interest
- Indicative Land Value
This gives a rough guide to what a developer could afford to pay. We then stress test every figure, reducing GDV by 5% and increasing build costs by 10%, to see how sensitive the deal is to market changes.
Example Calculation
A £2,000,000 GDV scheme for 600m² of new homes might look like this:
£2,000,000 GDV
- £500,000 Developer Profit (25%)
- £120,000 Planning and Professional Fees (6%)
- £1,260,000 Build, Contingency and Finance
= 120,000 Land Value (before adjustments)
Once we apply a 5% GDV drop and 10% build cost rise, the margin disappears completely, showing why so many valuations fall short of expectations.
| Then | Now |
|---|---|
| Profit 33% | Profit 25% |
| Build 33% | Build 65-75% |
| Land 33% | Land 5-10% |
Why Most Land Values Disappoint
We often see valuations that simply don’t add up. Years ago, land was valued on a simple thirds model, one third profit, one third build cost and one third land value. But that equation no longer fits today’s market.
Why the change?
- Consultant and planning fees can run into hundreds of thousands
- Every new scheme must now account for Biodiversity Net Gain (BNG), CIL contributions or Section 106 payments
- Affordable housing requirements reduce sales revenue
- Material shortages, inflation and supply chain delays have pushed costs up by more than 40% in five years
- Lenders still require a 20–25% developer profit to fund the project, meaning the only area left to adjust is land value
Our job is to show you how these factors affect your site and how we can still find a viable route forward through good design, planning and strategy.

Some Popular Myths ...
The Myth ...
“My land must be worth at least a third of the end value.”
The Reality ...
Did you know? – Planning and professional fees alone can exceed £100,000 on a small housing scheme. Understanding these costs early prevents disappointment later.
The Myth ...
“Developers over-inflate build costs to pay less for the land.”
The Reality ...
Did you know? – Even after planning permission, it can take six to twelve months before construction starts due to detailed design, warranty approval and funding checks. Patience and preparation are key.
The Myth ...
“I’ll get a better deal if I wait for the market to improve.”
The Reality ...
Did you know? – A 5% fall in GDV or a 10% rise in build costs can cut land value by more than half.That’s why realistic appraisals are essential before committing to any deal.
The Bellco Difference
- Every site we assess is tailored to the local area.
- Countryside villages don’t suit 80 homes a hectare, and sometimes two smaller semis will sell faster and make more sense than one large detached house.
- We design and appraise with the end market in mind, ensuring sustainable, saleable developments.
