Household and property insights built from non-PII data sources

Open the door to over 30 million households and access key property and household insights with The UK Household File

Introducing The UK Household File

The UK Household File (UKHF) is the most comprehensive, completely non personal and compliant view of over 30 million UK residential households and their properties.

Built using address only property data and highly accurate non-personal modelled household variables (derived from Open Source data), the UKHF gives you valuable consumer insight into property, lifestyle and behaviours to help you make better informed marketing decisions, whilst ensuring your business remains completely compliant with GDPR.

Powerful Analytical Data

The UK Household File is perfect for analysis and here’s why:

Detailed dataset

In addition to the detailed property information contained in the The UK Household File, we have developed a powerful dataset covering critical information such as:

Household composition

Occupation of householder

Analysis and modelling tools

Data is modelled at individual household level to create maximum granularity and differentiation.

It is then averaged across a number of properties of the same type in the same area to reduce statistical errors and create a robust outcome. The result is a profile for each property outlining the most likely values for each core variable for that property.

Data at this level of detail covering these core attributes provide modellers, marketers and analysts with powerful data which can:

Replace non-compliant legacy profiling tools

Enhance targeting using variables that make a real difference

Provide depth for models and insight

Over 50 key property data insights for every address

Data points for UK residential households / properties

Over 21 key variables for every UK address
