General Data Protection Regulation (GDPR)

Simunix provides data to their customers from a number of licenced and permissioned sources. These are:

  • Companies House
  • The Edited Electoral roll
  • Royal Mail
  • Ordnance Survey
  • Land Registry
  • Consumer Data

Additionally, Simunix can check all the records produced from these sources against the TPS and CTPS registers, which are updated daily.


(Please note: The following information is based on our understanding of the GDPR legislation and should not be interpreted as legal advice).

It is important that your business understands its responsibilities under the GDPR when conducting a marketing campaign using any of the above data sources.

Under the GDPR, direct marketing can be categorised as a legitimate interest, however, the campaign must be conducted in such a way that will not override the rights of the data subject.

Your business will need to run a balancing test to determine whether the rights of the data subject will not be overridden by your direct marketing campaign. Any measures that are implemented as a result of your balancing test will need to be documented internally so that they can be produced upon request. For example:

  • If you are marketing through sales calls, are the telephone and mobile numbers TPS and CTPS checked?
  • Do you apply an internal suppression against the customers that you have already marketed to?
  • Do you have clear rules in place regarding data retention and deletion?


Any complaints from data subjects regarding their inclusion should be directed back to the supplier:

  • Their Local Authority
  • Their telecoms provider

Entries in Companies House and the Land Registry are in the public domain.

If required, Simunix can help you trace the data source to ensure the complaint is channelled to the correct supplier.
