A new benchmark for property valuations

Most AVMs give you yesterday's news. Ours tells you what's happening now. We own UK's largest and most comprehensive homemover dataset, which sets the TwentyCi Automated Valuation Model (AVM) as a new benchmark in property valuation accuracy and confidence.

The Problem with Standard AVMs

Every AVM depends on data quality. Rubbish data in, rubbish valuation out. Most providers use the same stale, public records that lag months behind reality. Result? Valuations that miss the mark when markets move fast, and most likely, a broken trust.

What Makes TwentyCi AVM Different

We don’t just crunch historical sales data. We track what people are doing right now – the buying signals, the selling preparations, the market movement before it shows up in official records. Combining factual data with distinctive, predictive behavioural trends distinguishes our offering from others in the market.

How Our AVM Works

Our model combines different sets of information: past performance, what is happening now and what might happen in the future in the market.

Layer 1:

The Factual Foundation
(The “what”)

  • HM Land Registry: Price paid data for over 28 million addresses.
  • Energy Performance Certificates (EPCs): Detailed property attributes, including floor area, construction type, and energy efficiency.
  • Ordnance Survey: Precise location and geographical context.
  • Royal Mail PAF: Verified address information.

Layer 2:

The Behavioural Insights
(The “who” and “when”)

This is the unique TwentyCi differentiator. We overlay our factual data with the UK’s largest source of homemover data, drawn from over 25 billion data points. This includes observed, real-time signals of moving intent, such as:

  • Listing a property for sale or rent.
  • Engaging with conveyancers and removal companies.
  • Actively searching for property.

This isn’t guesswork – it’s observable market activity on a super-granular level happening before transactions complete.

Layer 3:

Advanced Machine Learning
(The “how)

Our algorithms process this data continuously, spotting patterns and adjusting to market shifts in real-time. The TwentyCi AVM doesn’t just look at historical comparables; it understands the real-time competitive landscape, demand pressures, and property-specific attributes to deliver a more nuanced and reliable valuation.
