Update on the previous comment - I did further research which pointed to these numbers being used by Verian Market Research. Sure enough, I got another call a couple of days later and it was them, following up on a survey I had taken part in. I've therefore updated the call type to "Survey"

Call received Friday evening 19:16. Did not answer as it was an unknown number, but given I had been called by 020 4557 5791 (1 different) earlier in the day, and that has been rated as negative, I suspect this the same.
