Breadth

The Experian pH Megafile has 30% more businesses documented than are captured by any one single data source.   We continually test potential new sources of data to validate their merit for inclusion.


Depth

We can provide you with a broader range of attributes available on any individual business, drawing on the strengths of the individual data sources, including a better fill-in rate, even on standard attributes such as employment size.


Coherence

Higher data quality is achieved by selecting the best supplier for each individual piece of information.  In addition to our main data sources, more than 10 other critical satellite sources are used for data enhancement purposes.  As well as keeping the files constantly up-to-date, storing historical values enables time-series trends to be analysed in many cases back to 1990.
