What's new February 2025

Article 4 restrictions

One of our most-requested features. Launching today, Plot Map now includes nationwide data on Article 4 restrictions.

A yes/no warning label as well as visual outlines on the map is shown for any Article 4 restriction affecting listed buildings, conservation areas or other land (such as HMO restrictions).

New Plot Map search


Site Plans in A3/A2

We've seen much more interest in our Site Plans download service than we expected, and by popular demand we have now added A3 and A2 paper sizes to the existing A4 size.

New Plot Map search


Visual Flood Risk

We've revamped our flood risk data, bringing it up-to-date with the latest 'Flooding from rivers and sea' dataset and now showing it visually on Plot Map with levels of risk, rather than a binary yes/no warning.

New Plot Map search


New conversion sourcing strategies

Our on-market sourcing algorithms now include two new strategies, for converting properties by adding an extra bedroom.

This uses our unique floorplan scanning to identify properties that have an excess of square footage for the current number of bedrooms.

Where does the raw data come from?

Property listings seen on rightmove.co.uk, zoopla.co.uk and onthemarket.com.

How often is the data updated?

The data is updated in near real-time.

What time period does the data cover?

This is a real-time market snapshot - the data covers currently listed properties. Once properties are removed from the portal, they are soon removed from this tab.

How is the raw data processed?

Duplicates from multiple sources are matched and reconciled as far as possible. Listings with obvious errors, where price or number or bedrooms appear out of range, are discarded.

What are the statistics used?

Averages shown are the interquartile mean, a type of average that is insensitive to outliers while being its own distinct parameter. The 80% range means that 80% of the listed properties fall inside this range.

How do you know the square footage of properties?

We use proprietary technology to read the square footage of properties from agent floorplans. Although we cannot determine the square footage for all properties, we can usually get sufficient coverage. Agents are sometimes known to inflate square footage, and this should be borne in mind as a weakness of this data.

Where does the raw data come from?

Property "price paid" data provided by the Land Registry.

How often is the data updated?

Once per month when released by the Land Registry, typically towards the end of each calendar month covering up to the end of the previous calendar month.

What time period does the data cover?

You can customise the time period using the filter at the top of the view. The default time period is up to 9 months back from today's date. The latest data covers the period up to 2024-12-30, although some sales that took place before this date may still be added in the coming months.

Where does the raw data come from?

Property "price paid" data provided by the Land Registry, and Energy Performance Certificate (EPC) data provided by Department for Levelling Up, Housing & Communities.

How do you know the square footage of properties?

We match the Land Registry data to EPC data provided by the Department for Levelling Up, Housing & Communities. Due to the fact that not all properties sold have had an EPC and vagaries of addressing in the UK, we are not able to determine the square footage of all properties, but we can usually get sufficient coverage.

The private paid data is updated once per month when released by the Land Registry, typically towards the end of each calendar month covering up to the end of the previous calendar month. The energy performance certificate database is updated monthly.

What is the yield calculation used?

The calculation used is (average_weekly_asking_rent * 52 / average_asking_price), expressed as a percentage. It is a top-line gross yield, meaning no expenses are considered.
