The merged Heart brought the addition of an additional sub-station, Heart Crawley & Surrey operates operationally separately. Sales are dealt with by a separate team (based in Crawley) – they may be based in Brighton in the near future though. In addition, to this Heart Crawley & Surrey also has a different website. On air though, both stations broadcast/simulcast the same core coverage with the exception of adverts (and select news features). Mercury FM and Heart have now completed the switchover and for the time being are operating out of both addresses.
