The council, which is the second largest in Wales, wants to bring in additional resources to assist the head of communications and marketing Mark Sharman, who heads a five-strong press team.
The chosen agency will cover a wide range of subjects, from core council business to tourism and inward investment.
Sharman said: ‘We have a massive agenda, from community services to lifelong learning, so there are a lot of messages that need to be dealt with and we are also engaged with our partners, the police and health boards, so the agenda is wide and growing. We are looking for a strategic partner and want someone who understands what we want to do.’
It is not yet known how much the contract will be worth but the agency that steps in will be the first external support to be brought in by the authority.
The provider is expected to review existing media relations, tied in with a continual media management review, as well as provide advice and support in advertising, database management and promotions, and will work alongside the council’s existing design arm.
Sharman said: ‘Inward investment is a major issue and we want to reach out to a wider audience. The task is to take our mindset outside the local media and look at a wider field. We want to maximise tourist opportunities so additional resources are important.’
Suppliers that want to be considered for the tender should apply by 24 March for a copy of the pre-qualification questionnaire.
Rhondda Cynon Taf has been nominated as best council for the Local Government Association Awards, which take place in March. It is the only authority in Wales to be nominated and is one of five shortlisted for the award.
