The UK’s Most Complete Property Data Resource

Every property carries a hidden timeline of lives lived, dreams chased, and milestones achieved. What if the data could tell the human story behind the bricks? DOMUS is the UK’s most comprehensive property attributes database which covers over 32 million residential properties. It offers exhaustive property information, providing the ‘DNA’ of a dwelling with attributes and characteristics specific to each property. DOMUS collects over 350 attributes about each property; these are updated daily from over 4,500 different data sources, which are both structured and unstructured. Property attributes fall into four main categories – location, property, environment and demographic factors – and range from square footage to risk factors.

DOMUS is built by using base data from Ordnance Survey’s AddressBase Premium product. It covers attributes of every single UK residential property, including the EPC performance data, as well as some commercial entities, such as shops, leisure establishments and holiday lets. See list of example attributes below.

Use Cases

flower-bullet-icon Marketing

DOMUS can help target the right properties for your marketing campaigns. For instance, you can identify four-bedroom houses with conservatories to focus your efforts on specific audiences.

It also allows you to exclude properties from your campaigns. For example, you can avoid sending marketing materials about garden accessories to individuals living in one-bedroom flats with communal gardens.

flower-bullet-icon Risk Management

DOMUS data can be utilised across various risk areas, including finance, portfolio management, environmental concerns, search risks, building risks, and voids. This will facilitate faster and improved decision-making in risk assessment and management.

flower-bullet-icon Financial Modelling

DOMUS can be used for modelling, including models for profiling, propensity, transition management and void management. DOMUS attributes are available separately or aggregated, as a one-off or being refreshed regularly to build models. The underlying authoritative data supports enhanced modelling capability, accuracy and coverage.

Frequently Asked Questions

1. How accurate is the data?

We have 99.6% coverage of all residential listings, which is the highest tracking rate in the UK, and use over 4,500 data sources, processing more than 640 billion pieces of data per year, updated daily. We employ strict data verification processes and work with industry-leading suppliers to mitigate issues. Our data is factual and not modelled or sentiment-based, which contributes to its accuracy. However, because some of the data comes from public sources, we acknowledge that potential errors can occur in individual cases such as incorrect listings due to administrative errors.

2. How easy is it to integrate DOMUS into our current systems?

  • Data Transfers – You can receive DOMUS via a secure data transfer (SFTP), either as a one-off exercise or periodically.
  • Data as a Service (DaaS or API) – If you do not want to deal with the challenges of big data sets, DOMUS is also accessible through a range of APIs which allow you to retrieve details of a specific property at a point of need.
  • Software as a Service (SaaS) – TwentyCi has also created many software solutions which allow users to search for a specific property and pull back a specific set of attributes.
