AVM confidence bands explained

A property valuation without a confidence band is a half-answer. It may look precise and arrive instantly, but a single number can hide the thing buyers, lenders and insurers most need to know: how much uncertainty sits behind it.

Planning permission as a property risk signal

Planning history is one of the most underused property risk signals in the UK. Most property teams know it matters for conveyancing, development and local market research. Fewer use it properly in valuation, rebuild cost, pricing or underwriting. That is a missed opportunity.

Beyond the Postcode: Unlocking Hyperlocal Property Insights for Smarter Insurance Decisions

The UK insurance market is fiercely competitive. To thrive, insurers need every advantage they can get. And in the realm of property risk, that advantage comes from precision. It comes from understanding the unique characteristics of individual properties, not just broad postcode averages.

The Transparency Imperative: Why "Black Box" Property Data is a Risk You Can't Afford

For too long, the property data industry has operated like a black box. Insurers and lenders rely on these providers for critical decisions - underwriting, pricing, claims - yet they often have little visibility into how those decisions are made.

The Climate Crisis is Here: Is Your Property Data Ready?

The climate is changing, and the insurance industry is on the front lines.  Extreme weather events - floods, storms, wildfires, heatwaves - are becoming more frequent and more severe.  Relying on historical data and postcode-level risk assessments is no longer a viable strategy.

The Future of Property Underwriting: From Reactive to Proactive (and Predictive)

Traditionally, underwriting has been a reactive process. Insurers assess risk based on historical data and static property characteristics, set a premium, and hope for the best. But what if you could predict risk before it happens? What if you could proactively prevent claims, rather than simply reacting to them?

Stop Guessing, Start Knowing: The End of "Fuzzy" Address Matching

In the world of property insurance and lending, an address is more than just a location; it's the foundation of risk assessment, underwriting, and portfolio management. But what happens when that foundation is shaky? What happens when your address matching is, well, "fuzzy"?

The Data-Driven Advantage: How to Uncover Hidden Opportunities in Your Existing Portfolio

In the quest for growth, insurers often focus on acquiring new customers. But what about the goldmine already sitting in your existing portfolio? Your back book holds a wealth of untapped potential - if you have the right tools to unlock it.

See The Future: How Chimnie Helps Predict Property Outcomes

Insurance and lending are all about predicting the future. What's the risk of a flood? Will a property increase in value? Will a borrower be able to repay their loan? Traditional methods often rely on historical data and broad averages.

The Future of Fraud Detection: It's Not Just About Spotting Crooks, It's About Protecting Honest Customers

Fraud is a major problem for the insurance industry, costing billions each year. But traditional fraud detection methods - relying on broad rules and manual reviews - are often inefficient and inaccurate.

The "Always-On" Underwriter: How Continuous Data Transforms Risk Management

The property insurance world is often seen as static. You assess a risk, write a policy, and hope for the best until renewal. But what if underwriting could be a dynamic, ongoing process?

Rebuild Costs: Why Market Value Isn't Enough (and What To Do About It)

In the insurance industry, we often talk about market value. But when it comes to protecting a property, market value is only half the story. The real cost - the cost to rebuild after a total loss - is often significantly higher.

It's Not About Technology for Technology's Sake. It's About Solving Real Problems.

Climate Adaptation: Is Your Geospatial Data Keeping Up?

Climate risks are intensifying, and the insurance industry is feeling the heat. Weather-related property claims are surging, driven by increasing flood, subsidence, and even air pollution events.

Why Rebuild Cost Needs to Behave Like a Model, Not a Calculator

The insurance industry often talks about rebuild cost as if it’s a single, knowable fact - like a postcode or a floor area. But rebuild cost isn’t that kind of feature. It’s closer to a weather forecast: you can estimate it, you can explain what drives it, you can quantify confidence, and you can improve it with better inputs - but making decisions as if it’s one precise figure can often be a mistake.
