All public bodies are already required under guidelines for the engagement of consultants to ensure that:
- a firm business case is properly established prior to the engagement process;
- consultancy services are acquired in the most economical manner in accordance with national and EU rules on procurement, specifically that consultants are appointed in an open, competitive and non-discriminatory manner that delivers best value for money;
- consultancies are managed effectively once engaged; and
- the output and impact of consultancies are adequately assessed.
The policy, therefore, on expenditure on consultancy services is quite firm: it must result in value for money for the public.
